Innovation

SPECIFICATIONS

For over 65 years, the name Titus has been synonymous with innovation in commercial air distribution. Many of the solutions we have developed over the years are still tried and true core products in our industry today. Intelligent Innovations speaks to our ability to solve problems and look at air distribution in new ways. Our true passion, however, lies in our ability to find clever and creative ways to enhance occupant comfort. Clever. Creative. Comfort. Several examples can be found within the pages of this catalog, and one of the stand-out products is the EOS; the industries first solar-powered, energyharvesting auto-changeover diffuser. Not only does the EOS provide THE solution for perimeter heating and cooling challenges, but it decreases the time it takes for an occupied zone to reach the setpoint, over the traditional split compromise diffuser, to improve occupant comfort. Additionally, the technology at work in the EOS provides us with a scalable energy

CORPORATE VALUES

harvesting platform to use as a jumping off point to address thermal comfort in revolutionary ways. Another cleaver and creative example innovation from Titus is the Plexicon. Displacement ventilation, while a great solution for cooling a space, usually requires a separate or supplementary system for heating; which affects the design, installation and overall cost of a project. The Plexicon addresses this challenge by incorporating displacement cooling and mixedairflow heating into a single diffuser assembly with auto-changeover action. Providing both cooling and heating from the same diffuser eliminates the need for a secondary heating system, reduces overall project costs, and delivers a high level of thermal comfort to the building occupants. At Titus, we are continually working on developing new ways to advance the science of air distribution.

Green Building design and energy conservation concepts are not new, yet in recent years the focus throughout the world has been to build structures with these principles in mind. We have seen the positive impact that designing and creating green buildings with these concepts have on our community and more importantly the world in which we live. As such, 100% of our focus for the past couple years and going forward has been on developing and delivering Green Solutions, and not just any Green Solution, but relevant Green Solutions. This is exactly the purpose of the Titus Energy Solutions website. The Energy Solutions micro-site is a first of its kind for any HVAC manufacturer in the industry. Our tagline, The Leader in Air Management is not just words. Titus is fully committed to provide the latest innovations to the HVAC market and this new website is just another piece to an ever-growing puzzle. By being singularly focused on Green products and Green Building CORPORATE VALUES

concepts, this website provides a portal into the latest developments in training, design, energy conservation, and news that directly affect us. We made every effort to incorporate all the tools needed to find the perfect Green Solution. Within the site you will find relevant product information, marketing collateral, LEED tools and other energy conservation related resources. We offer a wide array of Green products that can be used in a variety of applications. Whether you have a ceiling application or an underfloor installation, Titus has the Green Solution for you! Many of our products are GreenSpec Listed and we have a knowledgeable and experienced staff of industry professionals ready to provide assistance when needed. The marketing collateral we have made available on the Energy Solutions site is directly related to our Green products as well. The Energy Solutions

Brochure and the Retrofit Energy Solutions Guide are two brochures created to focus on Green products. The Energy Solutions Brochure is a 4-page guide that not only shows the types of products we offer, but highlights what LEED Credits they assist in achieving. The Retrofit Energy Solutions Guide provides a more thorough look into how an older building can be retrofitted and the energy savings available if new system or components were to be installed.

ENGINEERING GUIDELINES

Engineering Guidelines - Terminals

The selection and performance data contained in this catalog are the result of extensive studies conducted in the Titus engineering laboratories under professional engineering guidance, with adherence to sound engineering applications. They are intended to be aids to heating and air conditioning engineers and designers with skill and knowledge in the art of air distribution. The data have been obtained in accordance with the principles outlined within the American Society of Heating, Refrigerating and

Air Conditioning Engineers (ASHRAE) Standard 70, Standard 113, Standard 130 and AHRI 880. Although Titus has no control over the system, design and application of these products, a function which rightfully belongs to the designer, this data accurately represents the product performance based on the results of laboratory tests. Furthermore, the recommended methods of applying this information have been shown by field experience to result in optimum space air distribution.

Terminals, Controls and Accessories

Engineering Guidelines - Terminals

SINGLE DUCT This basic terminal consists of casing, a damper, a damper actuator and associated controls. In response to control signals from a thermostat or other source, the terminal varies the airflow through a single duct handling hot or cold air. In some applications the same terminal is used for both heating and cooling; a dual

DUAL DUCT, NON-MIXING Essentially the same as two single duct terminals side-by-side, this terminal modulates the flow of hot and cold air in two separate streams supplied by a dual duct central air handling unit. Because there is no provision for mixing the two airstreams, this terminal should not be used for simultaneous heating and cooling,

DUAL DUCT, MIXING

SINGLE DUCT, WITH HEATING COIL This is the single duct terminal described above, with a heating coil added. The coil may be of either the hot water or the electric type. The hot water coil is usually modulated by a proportioning valve controlled by the same thermostat that controls the terminal. Control for the electric coil is either 100% on-off or in steps of capacity, energized by contactors in response to the room thermostat. The single duct terminal with heating coil

FAN POWERED, PARALLEL TYPE (VARIABLE VOLUME) In this terminal a fan is added to recirculate plenum air, for heating only. The heating cycle occurs generally when the primary air is off or at minimum flow. Heat is picked up as the recirculated air is drawn from the ceiling space and the fan motor. Additional heat can be provided by a hot water or electric coil on the

which would result in stratification in the discharge duct. (When stratification occurs, the several outlets served by the terminal may deliver air at noticeably different temperatures.) The non-mixing, dual duct terminal is best used in an exterior zone, in which zeroto-low airflow can be tolerated as the temperature requirement shifts from cooling to heating. hot airflow changes first, and a change in cold airflow follows to maintain a constant total (mixed) volume. When equipped with DDC controls by Titus, both hot and cold inlets have velocity sensors, with the summation of flows computed by the microprocessor. No discharge velocity sensor is used. This dual duct terminal is often used in an exterior zone of a building or to ensure ventilation rates. is most often used in an exterior zone with moderate heating requirements. Since the terminal normally handles its minimum cfm in the heating mode, a dual minimum cfm or â&#x20AC;&#x153;flip-flopâ&#x20AC;? control can be added for increased heating airflow. Separate minimum cfm setpoints are standard with most DDC controls (available optionally on most other control types) and should be considered in design. A higher minimum cfm in heating mode will improve overhead air distribution performance. terminal. Because the fan handles only the heating airflow, which is usually less than that for cooling, the fan can be sized smaller than in the series flow type terminal (see below). During the cooling cycle, the fan is off and cool primary air is supplied from the central system. A backdraft damper prevents reverse flow through the fan. The flow of the primary air is regulated by variable air volume controls. Used in exterior zones.

TERMINAL CONTROLS AND ACCESSORIES

Here the terminal is designed specifically for mixing hot (or tempered ventilation) and cold air in any proportion. When equipped with pneumatic controls, there is a velocity sensor in the hot air inlet, but none in the cold air inlet. A velocity sensor at the discharge measures the total flow of air and sends the signal to the cold air controller. In the mixing cycle, the

function thermostat, together with the necessary change-over circuitry, makes this possible. Controls can be pneumatic, electric, analog electronic or direct digital electronic. Accessories such as round outlets, multiple outlets and sound attenuators may be added. The single duct terminal is most often used in an interior zone of the building, for cooling only.

FAN POWERED, SERIES TYPE (CONSTANT VOLUME) The fan runs continuously, fed by a mixture of primary and plenum air. The more primary air is forced in, the less plenum air is drawn in. The result is variable volume from the central system, constant volume (and sound) to the room. Because the central system need only deliver air as far

LOW TEMPERATURE FAN TERMINALS The fan terminal, with its inherent mixing, is well suited to handle the very cold air delivered by systems designed for air much colder than with conventional 55°F supply systems. In order to use standard diffusers, the primary air must be raised to

FAN POWERED, LOW PROFILE This series or parallel type terminal has a vertical dimension of only 10.5” for all sizes, to minimize the depth of ceiling space required. Notice in the diagram at the right that the recirculating fan is laid flat on its side, shaft vertical. In localities where building heights are limited, the low profile terminal saves enough space to allow extra floors to be included

With this type of control the terminal maintains the flow rate required to handle the heating or cooling load, regardless of system pressure fluctuations. It is the best choice where the system pressure will vary extensively and where precise control is essential. Key components in pressure independent control are the velocity sensor, which furnishes a continuous reading of the air velocity through the terminal, and the velocity controller, which processes this information along with signals from the thermostat. In the chart (Figure 55), vertical lines AB and EF represent minimum and maximum cfm settings which are adjustable at the controller. Line CD represents any cfm setting maintained by the controller in response to the thermostat. The damper will open and close as needed to hold the cfm constant up and down this vertical line for the full range of pressure drops shown. Notice that the vertical cfm lines are cut off by the diagonal line AE, which represents the pressure drop from inlet to outlet with the damper wide open. This is the minimum DP shown in our data.

ROOM THERMOSTAT OR SENSOR The thermostat contains not only a temperature sensing element, but also a means of changing the setpoint. The room sensor used with the direct digital control system is simply an electronic temperature sensor; setpoint changes are handled along with other signal processing in the digital controller.

PRESSURE DEPENDENT A terminal with this type of control is designed for those applications where neither pressure independence nor cfm limit regulation is required. An example is a variable volume makeup air supply in which the downstream duct pressure is held constant by other controls. The terminal consists essentially of a casing, a damper and a damper actuator. There is no controller and no velocity sensor; the damper moves in direct response to the thermostat or other signal input. The line AB (Figure 56) shows the typical performance characteristic. It represents a given damper setting, with the flow rate varying as the square root of the static pressure drop through the terminal. This, of course, is typical of any damper or fixed orifice. Lines CD and EF represent random additional settings as the damper opens to the full open position line GH. Line GH is the minimum pressure loss of the assembly.

PNEUMATIC SYSTEMS

Pneumatic

In a pneumatic control system, the various components are powered by compressed air, usually at 15-25 psi, from a central system. The thermostat receives air at full pressure directly from the main air supply. In response to room temperature, the air pressure is modulated to the controller, which regulates the damper actuator. The sensor and controller compensate for changes in duct pressure so that operation is pressure independent.

ELECTRIC SYSTEMS - FIGURE 58A Electric controls operate at low voltage, usually 24 VAC, supplied by a transformer which is often built into the control box of the terminal. The room thermostat has single-pole-double-throw contacts so that (in the cooling mode) a rise in temperature drives the damper actuator in the opening direction; a fall in temperature reverses the actuator. Since the electric system has no velocity sensor and no controller, there is no compensation for duct pressure fluctuations. Operation of the terminal is pressure dependent, the thermostat and room response time are typically much less than the actuator response time, and excessive room temperature variations are a likely result.

ANALOG ELECTRONIC SYSTEMS - FIGURE 58B Like the electric controls, analog electronic controls operate at low voltage, usually 24 VAC, supplied by a transformer which is often built into the control box of the terminal. These controls, however, also include a velocity sensor of either the thermistor type, or pneumatic velocity sensor with electronic transducer, together with an electronic velocity controller that is pressure independent. The electronic thermostat can control both cooling and heating operations. Because of the pressure independent operation and integrated thermostat, excellent room temperature control can be achieved.

The controller not only performs the reset and pressure independent volume control functions, but it also can be adjusted and programmed either locally or remotely for multiple control strategies, including scheduling. In addition, it can link to other controllers and interface with security, lighting, and other equipment. Control can be centralized in one computer.

Control Operation in Terminals

DAMPER OPERATION Linearity (Figure 61) is the ideal characteristic for most damper applications. How nearly linear the operation is depends upon the percentage of the overall system pressure drop contributed by the wide open damper. Pressure independent control operations eliminate the effect of nonlinear dampers, but simulate the effect of a true linear damper to the system. For a linear damper characteristic, the damper is sized to contribute about 10% of the overall system resistance. Also (Figure 62), actuator torque must be sufficient to close the damper under all design conditions. In Titus terminals, the torque is always more than adequate.

DIRECT ACTING/REVERSE ACTING PNEUMATIC THERMOSTAT ACTION

DIRECT RESET/REVERSE RESET PNEUMATIC VELOCITY CONTROLLER ACTION In the direct reset pneumatic velocity controller (Figure 65), an increase in thermostat output pressure causes a corresponding increase in controller cfm setting. The damper will open and close to maintain this cfm when duct pressures change. In the reverse reset controller (Figure 66) the same action results from a decrease in controller cfm setting.

In the direct acting pneumatic thermostat (Figure 63), a room temperature increase causes a corresponding increase in thermostat output. In the reverse acting thermostat (Figure 64), the sequence is the opposite. Because of these characteristics, direct acting thermostats are often used for cooling, reverse acting for heating.

Control Operation in Terminals (continued)

PNEUMATIC THERMOSTATCONTROLLER COMBINATIONS For systems supplying cold air when a direct acting pneumatic thermostat signals a direct acting controller (Figure 67), an increase in room temperature produces an increase in cfm setting. A reverse acting thermostat with a reverse reset controller produces the same result. A direct acting thermostat with a reverse reset controller or a reverse acting thermostat with a direct reset controller (Figure 68) will produce a decrease in cfm as the room temperature increases. With warm supply air, the logic is reversed.

ACTUATOR TERMINOLOGY

TERMINAL CONTROLS AND ACCESSORIES

B10 B10

Pneumatic actuators have an internal spring which is overcome by control air pressure. When air pressure is less than the spring tension, the actuator will retract. Depending on how it is connected to a damper, the damper may open or close on increase in control signal. Electronic actuators, however, are typically “fail stopped” unless they have a return spring which is activated by a loss of control signal. These are several times the cost of “fail stopped” actuators. When normally open or normally closed actuators are specified in an electronic control project, the requirement is most often in error.

NORMALLY OPEN

PNEUMATIC CONTROL/ ACTUATOR COMBINATIONS

This describes a pneumatic operator which is configured so that on loss of air pressure the damper in the unit will open fully. These applications are typically ones where all like units are desired to be open for control purposes such as smoke removal or to prevent excessive pressure on system start-up.

NORMALLY CLOSED When air pressure is removed, the actuator will cause the damper in the unit to go fully closed. This is typically specified when an area is to be isolated.

Controllers and actuators work in concert to control space temperatures. With pneumatic controls the most common combinations are Direct Acting Normally Open (DANO) and Reverse Acting Normally Closed (RANC). With most pneumatic controls special controllers are used for direct and reverse acting and any combinations other than DANO or RANC require extra components and increase air consumption. (With the Titus II controller, no extra components are required as the unit is switchable.)

Engineering Guidelines - Terminals

Velocity Controller Operation

Total Throttling Range of Thermostat

DEFINITIONS OF TERMS The controller setpoint is the cfm setting that the control system is calling for at any given moment. At that setpoint the damper opening may vary widely to compensate for any duct pressure changes reported by the inlet sensor, and thus hold the cfm constant.

% Max. Flow

(DDES)

With pneumatic systems, the setpoint, 11 psi in the example (Figure 69), can be reset by the action of the thermostat anywhere between the maximum and minimum cfm settings of the controller. The corresponding thermostat output pressures are called the start and stop points. The range of possible setpoints between the start and stop points is called the reset span, 8 to 13 psi in the example shown here. The thermostat may also control an auxiliary piece of equipment, such as a proportioning valve on a hot water coil, shown here modulating over a range of 3 to 8 psi, in sequence with the reset span of the controller. The overall range over which the thermostat controls these devices is its proportional band or total throttling range, 3 to 13 psi in this example.

This is the change in output signal caused by a change in room temperature. This rating (Figure 70) is usually 1째F = 2.5 psi for pneumatic systems. Electronic systems have a wide variance in output responses.

HYSTERESIS This is the failure of an object to return to its original position after a force has moved or deflected it. For example, in some velocity controllers (Figure 71) the cfm setting increases along the lower curved line and decreases along the upper curved line. At the setpoint, the cfm may be either A or B.

Velocity Controller Operation (continued)

PNEUMATIC FEEDBACK Signals from the thermostat determine the cfm setpoint of the controller. The duct velocity acting on the velocity sensor forms a feedback (closed) loop (Figure 72) that allows the controller to monitor the airflow resulting from its settings and make corrections continuously. This is a form of closed loop control and is used on both pneumatic and electronic pressure independent systems.

FAN TERMINAL FLOW CONTROL Engineers designing air systems try to match the airflow capacity of fan powered terminals to the needs of the space. Exact matches are rare, however. The design may not allow an exact match, a product other than the one which is the subject of the design might be selected, or system balancing might require a different airflow to meet field conditions. The two commonly used methods of trimming fan airflow are: •  Mechanical Trimming •  Voltage Adjustment

SERIES FAN SHIFT With Series fan terminals, the fan output is intended to remain constant over a range of primary inlet damper flow rates. With proper design, this is normally so. With improper design, or with additional inlet attenuators added to a terminal, the fan may see a different external pressure when in full induction mode than when in full cooling. This results in a variation in the quantity of air delivered to the space, or “Fan Shift.” The consequences of fan shift depend on individual zone characteristics and building design. If diffusers are selected such that they may add background masking sound at design flow, variations in flow may be an annoyance to the occupants. If a designed ventilation rate is assumed, this may vary if fan shift happens. (Titus terminals are designed to minimize fan shift.)

Figure 73. Forward Curved Fan Performance Curve

MECHANICAL TRIMMING Mechanical trimming involves the use of a mechanical device, such as a damper, to adjust the fan airflow to meet the design requirements. Typically, these are used in conjunction with a multi-tap motor to provide a greater operating range and keep the energy consumption and sound levels as low as possible. Mechanical trimming offers a lower first cost versus a voltage adjustment, but at increased operating costs and increased sound. Multi-tap motors are not always effective in changing flow. In operation, the mechanical device will raise the static pressure the fan operates against by either restricting the free area downstream of the fan or restricting the free flow of air drawn into the fan. A forward curved fan riding the fan curve will reduce airflow accordingly (Figure 73).

Although the rpm of the fan will increase, less work will be performed. This will result in a reduction of the amp draw of the fan motor. Since voltage remains constant, the overall power consumption of the fan is reduced. The power reduction from mechanical trimming is less, however, than the power reduction from voltage adjustment. When mechanical trimming is used, the sound levels of the fan terminal will increase. When the dampering occurs downstream of the fan, the velocity of the discharge air must rise, thereby increasing the discharge sound power levels. Additional sound contributions are made by the fan. The increased rpm of the fan results in greater tip speed. This occurs with either dampering method, raising the level of both the radiated and discharge sound.

Fan Terminal Flow Control (continued)

Engineering Guidelines - Terminals

Voltage adjustment of fan powered terminals typically involves the use of a silicon controlled rectifier (SCR). An SCR uses a triac to phase proportion (chop) the electrical sine wave.

FAN SPEED CONTROL The rpm of the motor is reduced by the SCR, lowering the tip speed of the fan. Since the free area downstream of the fan is not reduced, the velocity either meets design conditions or is lowered if the airflow is reduced below design for balancing purposes. There is no increase in sound from air disturbances.

A Note on Nameplate Ratings The amp draw can increase above the nameplate rating of the motor! The motor’s nameplate specifies the amp draw for one set of design conditions. Since the voltage to the motor is reduced, the nameplate rating is no longer applicable. If proper care is taken in the design, specification and selection of the motor by the terminal manufacturer, the increased amp draw will pose absolutely no problem in operation or longevity. Thousands of fan powered terminals shipped with SCRs over the years serve as confirmation. Titus accounts for the increased amp draw in the specification and selection of motors used for fan powered terminals. As a result, Titus specifies unit fusing adequate to handle the maximum amp draw possible under all operating conditions. This differs from the motor nameplate; it is essential that electric circuit fuses/overcurrent protection are sized according to the nameplate of the terminal, not the motor nameplate.

TERMINAL CONTROLS AND ACCESSORIES

As voltage to the motor is reduced, the motor tries to compensate and the motor’s amp draw rises slightly. The amperes will continue to increase until 50% of the current sine wave is phase proportioned. After this point, the amp draw will decrease. The increased amp draw is small relative to the reduction in voltage. As a result, comparing power consumption of the mechanical trimming method with the voltage adjustment method is analogous to comparing the power consumption of inlet guide vanes on central air handlers with speed inverters (Figures 75 and 76).

Watts

In effect, the SCR switches power off 120 times a second on a 60 Hertz cycle. This reduces the voltage to the motor, slowing its speed. In operation, the SCR responds to the current but controls voltage. Thus, while an SCR’s triac may be energized at zero current, the current sine wave generally lags the voltage sine wave with an induction motor. This results in the idealized voltage sine wave (Figure 74). As the SCR is used to further reduce fan speed, the true RMS value of the voltage is reduced.

The fan curves in a catalog represent the operating range of the fan powered terminal. Fan operation is dependent on the static pressure on the fan, so fan curves show airflow vs. static pressure. As the static pressure increases, airflow decreases. A typical fan curve will show maximum and minimum airflow for a fan powered terminal.

The SCR minimum is designed to protect the motor from operating below its recommended rpm. Most standard fan powered terminal motors must operate above a manufacturerâ&#x20AC;&#x2122;s specified rpm to effectively selflubricate.

However, the relationship between rpm and SCR voltage is dependent of static pressure. At minimum voltage on the SCR, the motor rpm will be different at different static pressures. Because of this, there is a possibility that at minimum SCR voltage, the rpm will be below the motor minimum recommended operating rpm. When this happens, the cataloged fan curve will use minimum rpm to set the minimum fan curve, not minimum SCR voltage. To ensure proper motor operation, always operate a fan powered terminal with the cataloged fan curve. A Note on Meter Usage Many Digital Multi-Meters (DMMs) will provide erroneous readings when attempting to measure current or voltage near an SCR. These meters are designed for normal, smooth sine waves. The SCR, by changing the shape of the sine wave, throws off the readings from these meters. To measure the current voltage, a true RMS DMM designed for these conditions must be used.

ECM MOTOR TECHNOLOGY The ECM motor is an ultra-high efficiency, brushless DC motor with a unique microprocessor based motor controller. Motor efficiencies of 70% or better across the entire operating range of the motor saves considerable electrical energy when compared to conventional induction motors. The motor controller, when tuned to the fan powered terminal, provides a large turn down ratio and constant volume airflow regardless of changes in downstream static pressure operating against the fan. With the introduction of the ECM motor, factory setting of the fan cfm is now possible. Separate controls are required to enable field adjustment of fan speed. The fan speed control allows adjustments to be made three ways.

ENERGY SAVINGS POTENTIAL The ECM motor, as applied to the Titus TQS fan powered terminal, offers significant energy savings over time to the owner when compared to conventional induction motors. Titus has evaluated an actual field trial and confirmed through bench testing an example of the potential energy savings when using the ECM motor. The following charts show the watt reduction associated with the ½ hp and 1 hp ECM motor when compared to standard TQS units of equivalent application range. TQS Size 6 - 1hp ECM Motor 1200 1000 800

Due to the way a standard split capacitor motor draws power, they have slightly fewer harmonic frequencies as compared to the ECM motor. The ECM motor, unlike the standard split capacitor motor, draws peak power only when needed, resulting in less electrical noise generation. As of 2011, the most stringent of limitations for harmonics is published in the CAN/CSA - CEI/IEC 61000-4-3-07 (R2011). These values set the ceiling for allowable harmonic levels. The critical maximum or peak amp values for a given harmonic level occur in the third harmonic closely followed by that of the fifth harmonic. Published data for a 1hp ECM without filtering capability violates these CEI limits. Titus has developed technology to decrease the harmonic frequencies while continuing to deliver peak power as it is requested. The Titus ECM motor meets the criteria, as well as specified national and international harmonic limitations.

Power for a given motor is drawn through the line in the form of a pure sine wave. This sine wave contains a fundamental frequency, in the US typically 60 Hz. When there exists other pure sine waves, each with individual frequencies, other than the fundamental frequency, they are called harmonics.These waves cause distortion or “noise” in the power line. Therefore, harmonic distortion is a collection of pure sine waves, including the 60 Hz fundamental frequency, which when summed together point by point in time creates distortion in the incoming line.

When evaluating this reduction in watts for energy usage the following table shows, at various usage rates, the annual savings per motor. Annual savings assume a run time of 3000 hours per year (250 days at 12 hours/day). Table 9. Annual Savings per Motor Usage Rate $0.05 $0.06 $0.07 $0.08 $0.10 $0.12 $0.14

Also, reduction in demand charges must also be considered. Typically, demand charges are calculated during a 15-minute peak window. Some utilities will qualify the peak demand to only the summer months and use this peak as the monthly charge throughout the remainder of the year while other utilities will calculate demand charges using that months peak kW requirement. The savings associated with reduced demand charges are substantial, as demand charges are usually several dollars per kW. As an example, a typical multi-story office application may require 200 fan terminals. Each fan terminal equipped with an ECM motor may have approximately 0.4 kW reduction in power. This translates to an 80 kW reduction in demand and with a demand rate of $10.00 per kW equates to a potential $800 per month reduction in the demand charges. While this model is simplistic, it is indicative of the payback potential of the motor. Utilities will vary not only in price but also in calculation methods with contract kW’s versus actual kW usage so actual savings must be calculated according to local market conditions. Coupling the usage and demand savings associated with the ECM motors can provide a substantial savings throughout the life of the building.

DIRECT DIGITAL CONTROL APPLYING COMPUTERS TO CONTROL With many years of experience, design engineers have established the basic principles of temperature control for heating, ventilating, and air conditioning (HVAC) systems. These control strategies have been applied utilizing conventional pneumatic, electric or analog electronic devices. Recent advances in micro-technology have made it possible to apply the power and precision of computers to HVAC control. Microprocessors, which cost less than ever before and offer superior computing power, are now suitable for application to individual air handlers, packaged heating/ cooling units, VAV terminals or the entire HVAC system.

DIRECT DIGITAL CONTROL Microprocessor-based controllers inherently perform direct digital control (DDC) and typically replace the conventional pneumatic or analog electronic controls. Digital controllers measure signals from sensors (input), process these signals in software (through the microprocessor), and initiate a corrective action to a controlled device (outputs) (Figure 80). A more technical definition is provided in the ASHRAE Applications Handbook.

ADVANTAGES OF DDC DDC systems offer several potential advantages over conventional counterparts. • DDC systems provide improved comfort and greater energy efficiency through precise and accurate control. Pneumatic and Analog systems utilizing proportional (P) control have the inherent characteristic of offset (Figure 81). Microprocessor based controls can eliminate offset by adding the integral (I) or reset action. Furthermore, addition of the derivative (D) action can result in a faster response and greater stability (Figure 82), but requires significant tuning. • DDC systems require less maintenance than conventional systems. Since there are no moving A direct digital controller receives electronic signals from the sensors, converts the electronic signals to numbers and performs mathematical operations on these numbers inside the computer. The output from the computer takes the form of a number, and can be converted to a voltage or pneumatic signal to operate the actuator.

parts, periodic preventive maintenance (PM) tasks such as calibration, lubrication, cleaning and adjustments are seldom required. • Control strategies can be modified quickly and easily without the need to rewire, repipe or install additional components.

• Since microprocessor controllers are software based, multiple control sequences can be preprogrammed in memory thus allowing a single controller to be fully interchangeable between different equipment. For example, an application specific VAV controller may be used to control single duct, dual duct or fan powered terminals by simply choosing the appropriate operating sequence from a software library maintained on board every controller (Figure 83). • While functioning completely independent, digital controllers perform all essential functions necessary to control different pieces of HVAC equipment without interconnecting to other computers. In this way each piece of HVAC equipment has its own digital controller in the same way conventional systems would provide individual control panels.

DDC DISTRIBUTED PROCESSING Using a concept commonly referred to as distributed processing, DDC controllers can function as standalone devices. In this way if one controller fails, others throughout the system can continue to function unaffected. The controllers are connected over a system communication bus or local area network (LAN) for system wide sharing of information. This information is used to perform sophisticated building control strategies not possible with conventional noncommunicating systems. The network also allows system access locally through a personal computer or remotely via modem over telephone lines (Figure 84).

CERTIFIED AIR TERMINALS

B18 B18

To provide engineers with sound power data which can be compared on an even basis, leading air terminal manufacturers joined together under the Air-Conditioning, Heating and Refrigeration Institute (AHRI) to develop an industry standard for rating air terminals and certifying performance data. The result was AHRI Standard 880, Air Terminals, and the 880 Certification Program. Standard 880 specifies the procedure, using a reverberant chamber, for developing sound power data. The certification program ensures manufacturers’ equipment performance meets their claims. Compliance with 880 is assured through third party testing. If a manufacturer fails to match claimed performance, the manufacturer must immediately rerate the terminal or lose the ability to use the AHRI Standard 880 seal. Another standard, AHRI Standard 885, was developed at the same time to assist the engineer in using certified product data. Terminal selection involves a series of trade-offs. The designer needs to try to balance all of the constraining factors and select the terminal which meets overall needs best. Engineers who specify AHRI Certified air terminals are assured that the manufacturer’s performance meets the manufacturer’s claims. This is protection for the engineer, the building owner and the building occupant.

SIZING SINGLE DUCT TERMINALS The starting point for sizing single duct terminals is to identify the type and model of controller. This is necessary because some controllers are more accurate at lower velocities than others.

Figure 84. System Access via Network Once the type of control is identified, the minimum and maximum primary airflows should be considered against the published cfm range. The trade-offs start here. Some engineers will select terminals near the bottom of the cfm range to reduce sound levels since large inlets reduce face velocity. Others select terminals near the top of the cfm range to hold down equipment costs. Still other engineers believe that one should remain comfortably in the middle to avoid potential control problems resulting from low velocities and sound problems occurring at high velocities. All Titus products operate extremely well within the published cfm ranges. Therefore, low velocity control concerns can be eliminated. This leaves sound and first cost as the key issues. If the terminal is relatively small to begin with and will be located over a kitchen or hallway, sound will probably not be of concern and the designer may choose to slightly undersize the terminal. If, on the other hand, the terminal is located over office space, the designer may slightly oversize the terminal. The selection of an appropriate water coil should also be considered at this time. In some cases, a terminal may need to be increased in size in order to obtain the desired heat output from the coil. With single duct units, the water coil air pressure drop should be subtracted from the duct pressure when determining sound generation. The sound produced by the damper is proportional to the pressure drop across the damper and discharge water coils may reduce that pressure drop. Other significant downstream pressure drops should be considered, and their pressure drop subtracted as well.

Sizing Terminals from Capacity Tables (continued)

Engineering Guidelines - Terminals

Parallel flow (variable volume) fan powered terminals are selected based on their capacity to handle the primary airflow. The same rules which apply to the selection of single duct terminals can be used, except that water coils are not in the primary airstream path, and will not affect sound levels. The pressure drop of the water coils, however, which are on the fan inlet in Titus parallel fan units, must be added to the expected discharge pressure at the fan flow rate when entering the fan curve tables. The fan is selected based on the minimum airflow requirements for the space or the heating load required. In most cases the fan can be downsized from the cooling flow requirement considerably, reducing both first cost and operating cost. The fan is selected from the fan curves. The downstream static pressure of the secondary air may not be the same as the primary air, however. If the secondary airflow requirements are less than the primary air requirements, the static pressure will be reduced. The following equation can be used to determine the static pressure at reduced airflows. (Do not forget to add water coil pressure drops to the fan requirement). Ps2 = Ps1 (V1 / V2)2 Where: Ps1 = Primary Air Static Pressure Ps2 = Secondary (Fan) Air Static Pressure V1 = Primary Air Velocity V2 = Secondary (Fan) Air Velocity To select a Titus parallel fan powered terminal, refer to the published fan curves and primary air pressure drop curves, together with the application and sound power data.

Since the primary and secondary airflows come from two different sources-and often at two different specified flow rates-the volume vs. pressure relationship in each of these airflows must be checked to ensure adequate flow rates under actual job conditions.

In the parallel flow type of unit, when the primary air is ON, the fan is typically OFF, and vice versa. As shown in the Figure 86, the primary air and the fan discharge air follow parallel paths into a common plenum.

SIZING SERIES FAN POWERED TERMINALS

Example: Select a Model DTQS for a maximum of 1200 cfm

Compared to single duct terminals, series flow (constant volume) fan powered terminals add the additional factor of fan cfm requirements. The designer must consider both the primary airflow and the fan. Series terminals are selected based on the capacity of their fans. The secondary (or fan) cfm should be equal to or slightly more than the primary air to ensure primary air does not short circuit through the induced air port into the plenum, thereby wasting energy. Before selecting the fan, the static pressure downstream of the terminal must be determined. This is the resistance of the ducts and diffuser(s) at design airflow rates.

Primary Air: From the table on page R11, a size 4 will handle 1200 cfm of primary air with a minimum static pressure drop of .18” through the primary air section. Since 0.50” static pressure is available at the inlet, the selection will work.

Once the downstream static pressure is known, the designer can select the fan based on the fan curves (these are shown throughout the catalog with the performance data for each fan powered terminal). The designer should find the intersection of the static pressure line on the horizontal axis and the fan cfm on the vertical axis. Selecting toward the upper end of the range will ensure that first costs are kept low and the fan motor efficiency is high. Selecting below the indicated minimum flow will result in shortened motor life as the bearings in the motor are centrifugally lubricated. If a water coil is needed, the designer must use the curves provided for a one or two row coil. These curves account for the additional static pressure generated by the coil. The static pressure added for an electric coil is negligible and may be disregarded. Neither has an appreciable effect on sound levels.

Inlet size must also be selected. Fan powered terminals come with varying inlet sizes. In general, inlets should be selected toward the bottom of the range. This reduces the face velocity of the inlet and minimizes the sound generated by the primary air valve.

B20

To select a Titus series fan powered terminal unit, refer to the published fan curves and primary air pressure drop curves together with the application and sound power data. An abbreviated table is shown at the right for use with the example discussed here. In the series flow type of unit, the fan runs continuously in the standard version. With the optional night shutdown and night setback controls, the fan can be cycled ON and OFF when the primary air is OFF. As shown in the diagrams below, the primary air is drawn into the fan inlet along with secondary (recirculated) air from the room. The maximum primary airflow must always be equal to, or less than, the total airflow through the fan. When the primary air section reduces its airflow in response to a reduced demand for cooling, the fan makes up the difference by drawing more recirculated air from the room. As a result, the flow rate to the room is constant. The primary air section discharges into the unit casing near the fan inlet, where the static pressure is slightly below atmospheric. For this reason, the available inlet pressure need only be enough to overcome the internal pressure drop through the primary air damper itself.

TYPICAL PROBLEMS

Engineering Guidelines - Terminals

The direct result of oversizing is low air velocity. With the velocity too low, the damper must operate in a pincheddown condition most of the time, making control difficult. The inlet velocity can also be too low for effective operation of the sensor and controller. Too low a velocity through an electric heater will cause the safety airflow switch to shut down the heater. Oversizing fan terminals results in low fan motor rpm and the potential for under-lubrication of the motor bearings, resulting in shortened motor life and additional sound from larger motors (Figure 89).

There may be noticeable temperature differences between rooms, since the thermostat is located in just one room as at the right.

The discharge temperature for terminal units should be selected so the maximum temperature difference between the room and the diffuser discharge is no greater than 15BF. This can be found in the ASHRAE Handbook of Fundamentals. According to ASHRAE 62.1, ceiling diffusers which have ceiling returns and are used for heating, should be mounted as shown to allow the supply air jet of 150 fpm to come down the exposed wall to within 4.5 ft. of the floor level. This reduces the short circuiting of warm air at the ceiling level and can be used to achieve an Ez air change effectiveness value of 1.0 as determined in ASHRAE Standard 129 for all air distribution configurations except unidirectional flow (Figure 95).

EXCESSIVE AIR LEAKAGE Leakage from the branch duct upstream and downstream from the terminal, as well as from the terminal itself, can be serious. In some installations it is found to be as much as 10% or more of the total airflow. Most of this leakage can be avoided by careful fabrication and installation and the use of top quality terminals (Figure 96).

In fan powered terminals, electrically or electronically controlled terminals, and all terminals with electric heating coils, the order to the factory should be carefully checked against the electrical characteristics of the power source at the point of connection.

Many terminals are light enough to need no support other than the duct work itself. However, the larger sizes, units with electric coils and fan powered models, are heavy enough to require additional support. A practical method is to use hanger straps screwed to the sides of the terminal. The bottom should be left clear where there are access panels (Figure 97).

WRONG TYPE OF INSULATION Installations in hospitals, clean rooms, and laboratories often require a special insulation liner to prevent air erosion or microbial growth. In the past, Mylar and Tedlar were often specified in these installations. Neither, however, meet current safety codes in many cities. Foil faced insulations, such as foil-faced Eco-Shield and Steri-Loc, provide the required covering, meet all safety codes and actually provide some sound attenuation. Titus Fibre-Free insulation provides both sound attenuation and resistance to erosion and mold growth (Figure 98).

The diameter of the inlet duct must be equal to the listed size of the terminal. For example, a duct that measures 8” in diameter must be fitted to a size 8 terminal. The inlet collar of the terminal is made ⅛” smaller than nominal size in order to fit inside the duct (Figure 100). Note: A duct should never be inserted inside the inlet collar of the terminal. For optimum control accuracy, a straight section of unrestricted duct at least 1½ diameters long should be installed at the inlet (Figure 101). Where this condition does not exist, field adjustment of the airflow setting on the velocity controller may be required.

If a round outlet adapter is furnished, it should be fastened and sealed by the same method used for the inlet. Close coupling the terminal inlet to the side of the main supply duct is not recommended. Where this condition is unavoidable, a flow straightening device (Figure 103) should be installed between the main supply duct and the inlet to the terminal. Even with the flow straightening device, the terminal may still require some field adjustment of the factory airflow settings at the velocity controller. Air leakage adds significantly to the operating cost of an HVAC system. Important savings are realized by carefully fitting and sealing all duct joints and specifying tightly constructed Titus terminals. The Titus box has very low damper and casing loss leakage. These values can be found on page Q26.

The example in (Figure 104) shows how many dollars can be lost in the leakage from just one terminal together with its connected duct work. Multiply that amount by the hundreds or thousands of terminals that may be in one building, and the seriousness of the loss is apparent. This is a conservative example, in that the leakage is only 5%; a much higher percentage is found in many installations. Also, the compressor, pumps, and fans may not run as efficiently as indicated here, and the cost of electric power in many parts of the country is greater than $0.06 per kilowatt hour.

PRESSURE MEASUREMENT

Engineering Guidelines - Terminals

1. Static pressure may be thought of as the pressure in a tire or storage tank. It is exerted in all directions equally. 2. Velocity pressure, as its name implies, is entirely a function of air velocity and its direction. It is the pressure you feel against your hand if you hold it outside the window of a moving car. 3. Total pressure is the sum of static pressure and velocity pressure. It and static pressure are the pressures actually sampled by velocity sensors in terminals and by commonly used measuring devices, as described next.

PT Pitot Tube

Connecting Tubing

The interaction of static, velocity, and total pressures is illustrated by (Figure 105). The Pitot tube, which is used to measure velocities and pressures, is really a tube within a tube. The inner, or impact, tube senses both the velocity pressure and static pressure combined (total pressure). The outer tube, which communicates with the airstream through small holes in its wall, avoids the impact of the air movement and senses only static pressure.

Once the velocity pressure is known, the velocity can be calculated easily:

Pv =

V 4005

B PS PV Difference in Liquid Level

PT PT minus PS = PV

or V = 4005√Pv

where V = Air Velocity and Pv = Velocity Pressure Knowing both the velocity and the cross-sectional area of the duct, the flow rate is then:

cfm = Area x Velocity

Electric Coils

REHEAT COILS: Several types of terminal devices are available with reheat coils, both hot water and electric. When determining the heat requirement for a terminal, the engineer will often start with the known zone heating demand, typically expressed in BTUH, or more conveniently, MBH (thousands of Btu’s). The room load requirements for heating are then used to determine the Room Entering Air temperature (EATr) by the equation:

By solving for the EATr, the coil Btuh requirements can then be determined. The room entering air temperature (EATr) now becomes the required LAT of the VAV box (ignoring any duct heat losses). The coil can now be sized according to:

Where;

LAT = Coil leaving air temperature EATc = Coil entering air temperature (primary or mixed air) Q = Flowrate (cfm)

EATr = Temperature (°F) entering the room Tr = Room setpoint temperature or average temperature Q = Flowrate ( cfm) (typically 30 - 50% of the cooling cfm)

Now that the coil requirements are known, published catalog data may be used to select the proper hot water or electric coil.

Btuh (room) = 1.085 * (EATr - Tr) * Q

Btuh (coil) = 1.085 * (LAT - EATc) * Q

Acoustical Applications and Factors

ACOUSTICAL APPLICATIONS AND FACTORS

B28 B28

Air terminals are the most noise sensitive of all HVAC products since they are almost always mounted in or directly over occupied spaces. They usually determine the residual background noise level from 125 Hz to 2,000 Hz. The term “Air Terminals” has historically been used to describe a number of devices which control airflows into occupied spaces at the zone (or individual temperature control area) level. There are two types: those that control the amount of airflow to a temperature zone (Air Control Units, ACUs, or more commonly “Boxes”), and those that distribute or collect the flow of air (Grilles & Diffusers, GRDs). On some occasions, the two functions are combined. As these two elements are the final components in many built-up air delivery systems and those closest to the building occupants, both are critical components in the acoustical design of a space. There is also a critical interplay between acoustics and the primary function of these devices; providing a proper quantity of well mixed air to the building occupants. Before discussing types of devices, we must have an understanding of some issues regarding sound levels in occupied spaces. The sound level in an occupied space can be measured directly with a sound level meter, or estimated from published sound power after accounting for room volume and other acoustical factors. Sound level meters measure the sound pressure level at the microphone location. Estimation techniques calculate sound pressure level at a specified point in an occupied space. Measured sound pressure levels in frequency bands can then be plotted and analyzed, and compared with established criteria for room sound levels.

for Air Terminal devices are usually reported as the sound power level in each of several octave bands with center frequencies as shown in Table 11. Sound Power Levels are given in decibels (dB) referenced to a base power in watts, typically 10-12 watts. Sound power levels can also be reported for full or 1/3 octave bands, but usually as full octave bands, unless pure tones (narrow bands significantly louder than adjacent adjacent bands) are present.

NOISE CRITERIA (NC) Sound Pressure Levels (Lp) are measured directly by sound level meters at one or more points in a room. They reference a pressure rather than a power. A product’s estimated Sound Pressure Level (Lp) performance curve is obtained by subtracting space (or other appropriate) sound attenuation effects from the unit sound power (Lw). Currently, most Air Outlet and Inlets (GRDs) sound performance is reported by subtracting a 10 dB attenuation from all octave band sound power levels, and determining the NC rating. This room effect approximates a 3,000 cu. ft. room, 10 ft. from the source for VAV boxes, which peak in lower frequencies, and a 2,500 cu. ft. room 7 ft. from a diffuser, which typically peaks @ 1000 Hz. (This is defined in the AHRI Standard 885 space effect calculation described later in this section). NC curves were developed to represent lines of equal hearing perception in all bands and at varying sound levels. Most air terminal products are currently specified and reported as single number NC ratings.

Sound power cannot be measured directly, (except using special Acoustic Intensity techniques), and is a measure of the acoustical energy created by a source. It is normally determined in special facilities and reported for devices under stated conditions. Sound Power Level (Lw) values

The 10 dB room effect which has been traditionally used for diffuser sound ratings, which typically peak in the 5th band, can be considered to be equivalent to a room about 2,500 cu. ft. in size, with the observer located about 7 ft. from the source. With VAV terminals, which peak in lower bands, the “10 dB” room size is larger, or the distance is greater.

NC ratings have been common in specifications for a number of years, with an NC-35 being the most common requirement. While NC is a great improvement over previous single number ratings, including Sones, Bels, and dBA requirements, it gives little indication of the “quality” of the sound. A more comprehensive method, RC, has been proposed; while a good analysis tool, RC is a very poor design tool.

ACOUSTICAL APPLICATIONS AND FACTORS

The use of a 10 dB “room effect” as used in this example, while in common practice and accepted for Table 12.

ROOM CRITERIA (RC)

Engineering Guidelines - Terminals

Room Criteria (RC) is based on ASHRAE sponsored studies of preference and requirements for speech privacy, along with ratings for “Acoustical Quality.” RC ratings contain both a numerical value and a letter “Quality” rating. The RC numerical rating is simply the arithmetic average of the sound pressure level in the 500, 1,000 and 2,000 Hz octave bands, which is the speech interference level (SIL). These are the frequencies that affect speech communication privacy and impairment. Studies show that an RC between 35 and 45 will usually provide speech privacy in open-plan offices, while a value below 35 does not. Above RC-45, the sound is likely to interfere with speech communication.

Don’t destroy acoustic privacy

Not too loud

Avoid hearing damage Don’t interfere with speech

Not to annoying

No rumble, No hiss No identifiable machinery sounds, No time modulation

In addition to the numerical SIL portion of the RC method, there is a “Quality” portion of the RC rating which involves an analysis of potential low and high frequency annoyance. The goals of acoustical quality are described in Table 13. Recommended NC and RC goals for various space applications, given in the current ASHRAE Handbook, are shown in the table to the right.

These letters are determined by analyzing the low and high frequency spectra compared to a line drawn with a -5 dB slope per band through the numerical RC point @ 1,000 Hz. This establishes the SIL (Speech Interference Level) line. Lines of -5 dB slope create the RC chart, shown in (Figure 128).

If the sound spectrum being analyzed exceeds a line drawn parallel to the SIL line plus 3 dB in the higher frequencies (> 2,000 Hz), the “hiss roof,” then it is declared to be “Hissy” and gets an “H” designation.

ACOUSTICAL APPLICATIONS AND FACTORS

When room sound levels are analyzed using RC curves, air diffusers tend to give the same ratings as they do in an NC analysis. Boxes, on the other hand, which are typically predominant in lower frequency sound and often characterized as “Roar” (250-500 Hz), often yield RC values lower than NC, but with an “R” classification.

AIR TERMINAL SOUND ISSUES

Octave Band Center Frequency, Hz

Figure 130. Rumble and Induced Vibration (RV) Spectrum

Sound is an important design criterion in the application of air terminals. In the context of the total building environment, comfort cannot be achieved with excessive sound or noise levels. By definition, sound is a change in pressure for a medium, such as air. This change in pressure involves a radiation of energy. Energy is used in the generation of sound and this energy is radiated from a source. All sound has a source and travels down a path to a receiver. Air terminals are one source of sound in a mechanical system. The path for sound emanating from the air terminal is through the plenum or down the duct into the conditioned space where it reaches the occupant or receiver.

Sound Power L w C = Casing Radiated and Induction Inlet D = Discharge Sound O = Outlet Generated Sound

B32 B32

If the plotted spectra exceed a +5 dB Rumble roof in the lower frequencies, it gets an “R” (Rumble) Rating. Finally, if the sound spectrum enters the “A” or “B” zones in the very low frequencies shown on the RC graphs, it warrants a “V” for possible wall or furniture vibration induced by acoustical energy in low frequencies. The B region may be characterized as “Be Careful” where one may have complaints, but the “A” region is “Awful”, and complaints should be expected. This is an example of an RV spectrum.

Mechanical system designers should not be concerned so much with sound, but rather with noise. Noise can be thought of as unwanted or excessive sound. Good design practice dictates that a designer establish the acceptable noise for the occupied space and then determine the selection criteria for the mechanical system components. In any application, both radiated and discharge sound should be considered. Radiated sound “breaks out” from the terminal casing or induction port and travels through the plenum and ceiling to enter the occupied space. Discharge sound travels out the discharge of the terminal through the duct work and outlet to enter the occupied space.

ENVIRONMENTAL ADJUSTMENT FACTOR In order to use the AHRI 885 Standard, sound power must be corrected for differences between reverberant room and free field calibrations when AHRI Standard 880 sound power is the base. This Environmental Adjustment Factor is listed in AHRI Standard 885.

Octave Band

Env Factor

To determine the maximum allowable radiated sound power levels for a project, the attenuation from the ceiling/space effect must be added to the desired room sound pressure for each octave band.

CEILING/SPACE EFFECT AHRI Standard 885 combines the effect of the absorption of the ceiling tile, plenum absorption and room absorption into the Ceiling/Space Effect. Experience has shown that the Sound Transmission Class (STC) rating for ceiling tiles, which is based on a two room pair test, is not well correlated with observed data for a noise source located above a ceiling. The AHRI Standard 885 Ceiling/Space Effect table D14 Table 16 is derived from a number of manufacturers’ observations and is only found in the AHRI Standard. This table assumes that the plenum space is at least 3 ft. deep, is over 30 ft. wide or lined with insulation and that there are no penetrations directly under the unit. From the AHRI Standard, the following attenuation values, or transfer functions, should be used for the Ceiling/Space Effect: Once the Ceiling/Space Effect has been determined, they are added to the sound pressure level to determine the maximum acceptable sound power levels. This must be done for each octave band. LW RAD =

B ACOUSTICAL APPLICATIONS AND FACTORS

According to AHRI Standard 885, an Environmental Adjustment Factor must be applied to manufacturers’ data if the sound power data has been taken under a free field RSS (reference sound source). According to AHRI, this is “necessary because at low frequencies, all real occupied spaces behave acoustically more like reverberant rooms than open spaces (free field).” In other words, manufacturers’ sound power data which is based on ILG/ RSS with a free field calibration must be adjusted to match actual operating conditions found in the field. This applies to Titus and other participants in the AHRI Standard 880 Certification program. For data rated per AHRI Standard 880, the environmental adjustment factor must be subtracted from the manufacturers’ sound power level data in order to use the adjustments provided in AHRI Standard 885.

AHRI Standard 885, Procedure for Estimating Occupied Space Sound Levels in the Application of Air Terminal and Air Outlets, provides the most current application factors for converting rated sound power to a predicted room sound pressure level. This standard is the basis by which most air terminal manufacturers convert sound power, as measured in reverberant rooms per ASHRAE Standard 130 and rated in accordance with AHRI Standard 880, to a predicted room sound pressure level. The standard provides a number of equations and tables available elsewhere, but puts them all in one document, and includes some unique tables as well. It also includes examples and diagrams to make the process easier to use. The most important of those are included here.

DISCHARGE SOUND POWER LEVELS

ACOUSTICAL APPLICATIONS AND FACTORS

B34

Engineering Guidelines - Terminals

Discharge sound (sometimes called airborne sound) is the sound that travels down the duct and discharges into the room along with the conditioned air. The procedure for determining the maximum acceptable discharge sound power levels requires the addition of the space effect, end reflection, duct insertion, flow division (or branch power division) and elbow and tees to the maximum acceptable room sound pressure levels. If more than one outlet supplies air to a room, separate evaluations should occur for each discharge path. This is done for each octave band. Space Effect. The discharge sound space effect is determined in the same manner as the radiated sound space effect. The sound source in this case might be the outlet (i.e., grille or diffuser) supplying air to the space, or may be sound from an upstream noise source (damper or fan) which passes through the outlets, or a sum of both Table 12. End Reflection. When the area across the airstream expands suddenly as the duct work terminates or ends at the outlet to the occupied space, a significant amount of low frequency sound is reflected back into the duct work. This is called end reflection. The amount of end reflection varies based on the inlet size and type of duct. Table 17. End Reflection dB(Table D13, AHRI Standard 885) Eq. Dia. or Duct Width 6”

Duct Insertion Loss. The addition of lined duct work results in significant attenuation of higher frequency sound. The amount of attenuation varies with duct size and lining thickness. AHRI Standard 885 contains several tables helpful in determining the appropriate attenuation values. Each section of duct work inserted downstream of the terminal must be evaluated. For example, one might have separate duct insertion attenuation values for straight lined discharge duct, branch duct (if lined) and flex duct from the branch to the outlet. The AHRI Standard, as well as the ASHRAE Handbook, provide tables of insertion loss per foot of duct based on inside duct dimensions.

Once all of the attenuation factors have been determined, they are added to the sound pressure level to determine the maximum acceptable sound power levels. This must be done for each octave band, and again the Environmental Adjustment factor must be added.

Attenuation

Elbows and Tees. A certain amount of attenuation of higher frequency sound is gained when an airstream enters an elbow or tee duct connection. If the elbow is round and unlined, the attenuation is considered by AHRI Standard 885 to be negligible. Attenuation of rectangular tees is determined by treating the tee as two elbows placed side by side.

Once the Radiated and Discharge sound pressure paths and effects are known, the resulting room sound level can be evaluated. Other factors may play a part in determining the final room sound levels. All these factors must be included to achieve an accurate prediction or analysis. The results may be very complex. In the example here, many paths are shown. In practice, only a couple are significant, but changes in designs may make a one time insignificant path become predominant. For example, should duct lining be eliminated and no flex duct employed, discharge sound may be much more important than radiated, the usual acoustical problem. Poor duct design may cause duct breakout to be the highest sound heard in the space.

All the sound paths must be combined to predict the room sound level. When combining path elements, the math is done using log addition, not algebraically. Logarithmic (log) addition requires taking the antilog of the dB in each band, adding them together, then taking the log of the answer. While this sounds complicated, (Figure 133) here shows an easier way of estimating the result. More importantly, most people cannot differentiate between two sources which differ by less than 3 dB. If the background sound is an NC-35, and the device in question is predicted at an NC-35, it is likely that the space will be at an NC-38 (although this is dependent on which octave bands are critical), but most people cannot hear the difference. In a similar manner, sound from VAV boxes and diffusers combine to create the room sound pressure level. Since they peak in different bands, however, they often complement each other. In many cases, a Series Fan Terminal will be predicted to have an NC-30 in a space, but when combined with an NC-40 diffuser, will result in a room sound pressure level of NC40, which is optimum for providing speech privacy in open plan spaces.

Maximum Sound Power Levels

A proper specification for acoustical performance in a space will limit the maximum sound generation for a product. This should be based on the desired resultant sound in the space and accepted and clearly stated sound path attenuations/ reductions. AHRI Standard 885 provides a consistent method for accomplishing this task.

Example:

A designer wants to achieve RC 40N for an open office to achieve an acceptable level of speech privacy. The office has a 9 ft. ceiling and a volume of 3,000 ft.3. The terminal will be located over the occupied space with 5 ft. of lined duct on the discharge.The lined discharge duct is 14” x 14” outside with one inch of insulation (12” x 12” internal cross section). This duct branches into an unlined trunk duct with two runs of lined flex duct taking off to the outlet. The flex duct is 6 ft. long and 8” in diameter. The terminal will supply 600 cfm with each diffuser taking 300 cfm. The ceiling is made of ⅝ inch mineral fiber tile with a 35 lb. ¼ ft.3 density. The diffuser is selected to provide an NC 40(N) at design flow.

DESIRED ROOM SOUND PRESSURE LEVELS From AHRI Standard 885 the appropriate sound pressure levels for an RC 40 can be determined. Since a Neutral Spectrum is desired, the Rumble Roof and Hiss Roof can be added to the spectra and still result in a neutral designation. The resultant maximum room sound pressure spectra are: Table 24. Maximum LP for (RC 40N), dB 2

• Whenever possible, terminals should be located over areas less sensitive to noise. This includes corridors, copy rooms, storage rooms, etc. Quiet air terminals facilitate the location of terminals over unoccupied space as with these units larger zones are possible resulting in fewer terminals. This also reduces first cost and improves energy efficiency. • The use of lined duct work or manufacturers’ attenuators downstream of air terminals can help attenuate higher frequency discharge sound. Flexible duct (used with moderation) is also an excellent attenuation element. • Sound will be reduced when appropriate fan speed controllers are used to reduce fan rpm rather than using mechanical devices to restrict airflow. This form of motor control is often more energy efficient. • The air terminal and the return air grille location should be separated as far as possible. Radiated sound can travel directly from the terminal through the return air grille without the benefit of ceiling attenuation. • Designing systems to operate at low supply air static pressure will reduce the generated sound level. This will also provide more energy efficient operation and allow the central fan to be downsized. • Sharp edges and transitions in the duct design should be minimized to reduce turbulent airflow and its resulting sound contribution.

Octave Band Center Frequency, Hz Figure 136. Fan Powered Terminal or Induction Terminal - Summary Calculation, Sound Sources and Paths It can be seen that discharge sound is not likely to be a problem, especially in the mid-frequencies. If duct lining is eliminated, however, the maximum allowable power is reduced by the duct insertion loss data on the previous page. If flex duct is disallowed, the maximum sound power allowed is further decreased by flex insertion loss. This can result in the following requirement for the unit: 2

No Lining/Flex

In many cases, this is a borderline acceptable case for many unit sizes and flow rates, especially in smaller rooms with RC 35N requirements. Flexible duct can be included as a solution to discharge noise in these cases.

DIFFUSER SPECIFICATIONS Diffusers are commonly specified and reported in NC, rather than RC. In most cases, there is no difference between NC and RC for diffusers as they usually peak in the 500-2,000 Hz region, and the resultant numerical specification is the same for both NC and RC. Diffuser NC ratings commonly subtract 10 dB from measured sound power levels in all bands to account for room attenuation. As described earlier, this will be a valid assumption for a number of combinations of room volume and distance to the source. While an ideal specification will be based on octave band sound levels, these are seldom available for diffusers, and so the NC rating must be used. For a close approximation of diffuser sound power when only NC is known, one can assume that the sound power for the diffuser in the 5th octave band (1,000 Hz) is equal to the reported NC plus 10 dB, the 4th band (500 Hz) is 3 greater than this, and the 6th band (2000 Hz) is 5 less. This will be suitable for most applications.

Diffusers, moreover, have typically been tested in the same facilities as VAV terminals, with the same reference sound source, and therefore the AHRI Standard 885 Environmental Effect must be included as well. The following is a proposed procedure for determining the Diffuser NC requirement based on an RC analysis: Steps: 1. Determine the desired RC level for the space. This is the sound pressure level requirement in the 5th band. 2. Determine the room effect in the 5th (1,000 Hz) band, based on room volume and distance to the diffuser from the observer. Add this to the RC number. 3. Subtract 10 dB from the result in Step 2. This is the required diffuser NC.

B ACOUSTICAL APPLICATIONS AND FACTORS

Octave Band

The room sound pressure level requirements should be based on the resultant desired acoustical environment. As the only attenuation element for diffusers is the room effect, this should be the primary attenuation path.

Diffuser Specifications (continued)

Example: The open office from the previous example is

used here. The room is large and speech privacy is desired, requiring an RC 40N specification. Steps: 1. From AHRI Standard 885 (or ASHRAE) the appropriate sound pressure levels for an RC 40 can be determined. In the 5th band the RC is = to the sound pressure level requirement, 40 dB. 2. The room absorption is determined from the space effect equation. With a 10 ft. ceiling and the terminal located a few feet away from the receiver, the distance variable will equal 10 ft. The volume of the room is 3,000 ft.3. The frequency varies with the octave band. The space effect in the 5th band will be obtained from Table 12, page B29, and is = 11 dB. 40 + 11 = 51 dB.

As the estimated room sound pressure level exceeds the rumble roof in the 2nd band, this unit must be classified RC 29 (R). If an RC 35 (N) diffuser is also supplied, however, the sound from it must be added to the terminals to get the room total sound level. Using the procedure described under “Diffuser Specification”, we can estimate the sound power level of an NC-35 diffuser:

Octave Band

Terminal Spl

Log Sum

Diffuser Pwl

DETERMINING COMPLIANCE TO A SPECIFICATION When determining if a unit will meet a specification, it may be necessary to conduct a total room sound evaluation with multiple sound sources and multiple paths. These are added using logarithmic addition to determine total sound level. Once all path elements are identified, the noncritical paths can be determined using (Figure 133), page B36. Paths which are 10 dB or more below the loudest, in any given band, can usually be ignored. VAV terminals, if evaluated by themselves, often result in an “R” classification because of the high mid-frequency absorption provided by lined and flexible duct. The diffuser, however, can overcome this apparent “Rumble” spectra by filling in the resultant sound with its high frequency sound generation. This results in an “N” rating, as required. Using the estimated sound power procedure from the Diffuser Specification section above, the diffuser’s contribution can be added (using log addition) to the VAV boxes sound pressure level, and a resultant sound pressure level classification developed. Example: A project engineer desires a space sound pressure level of RC 35(N) for a private office. He has selected a Titus TQS Fan Terminal, size 5-12, at 1500 cfm, with a design inlet pressure of 1 in. static pressure. From the sound tables for the product, the sound power levels for this unit and the reduction factors as in the previous example are shown above: Octave Band

Unit Pwl

C/S (Table 16)

Env Effect (Table 15)

Estimated Room Spl

The RC = (41 + 36 + 29)/3 = 35. The rumble roof for this spectra is therefore: Octave Band

Rumble Roof

Therefore the sound pressure level in the space is an RC 35 (N). This works because diffusers and VAV terminals seldom peak in the same frequencies, with diffusers being critical in the speech bands (500-2,000 Hz) and boxes producing the most sound in the 125-250 Hz region. When these two sounds combine in the space, they often complement each other, producing a full spectrum of sound and resulting in an “N” rating.

Engineering Guidelines - Terminals

Breakout - Sound which passes through the walls of a duct or device and is passed directly to an observer.

in each frequency band, and is a function of room volume and distance from the source.

Casing Radiated Sound - A type of Breakout Sound which passes

Terminals (Boxes) - Devices which vary the flow through a duct with

through the walls of a device. In some cases, it includes induction port radiated sound as well.

dBA - A single number rating of a broadband spectrum. Typically used

to rate outdoor noise levels. Not practical for use in rating indoor sound levels as it bears little relevance to occupants’ needs.

Discharge Sound - Airborne sound which is transmitted through ductwork from a noise source to an observer.

End Reflection - The reduction in sound, typically in low frequencies only, resulting from a rapid change in the shape or size of a duct or a duct termination.

Environmental Adjustment Factor (Environmental Effect) - A

correction required to accurately use data obtained in accordance with AHRI Standard 880, it corrects for a calibration difference between the Free Field calibration of the Reference Sound Source and the reverberant field in which it is used.

Incoherent Sound - Sound which is broadband and contains no repeating fluctuations.

Induction Port Radiated Sound - That sound which passes out

from the induction port of a VAV device. In practice it is impossible to differentiate from Casing Radiated sound, and is reported as a combined value under Casing Radiated sound levels.

Insertion Loss - The reduction in sound resulting from inserting an attenuation device, such as a section of lined duct. The difference before and after the insertion of such a device is the insertion loss.

Multiple Outlet Effect - When an airstream is split, the sound

traveling in the duct is also reduced, typically in proportion to the percent of airflow in each duct. The amount of reduction must be calculated logarithmically, not arithmetically, however.

Pure Tone - A sound spectrum which is very concentrated in a narrow band.

Radiated Sound - Sound which travels from the source to the observer in a direct path, outside ductwork.

Room Effect - Typically a 10 dB reduction in all bands, this is the

assumed value for attenuation of a room. In practice, it is reasonable for diffusers which peak in the mid-frequencies, but not necessarily for VAV terminals, which peak in lower frequencies.

GLOSSARY

Sound Power - The energy released as acoustic energy by a device. It is measured indirectly by one of several methods. It is reported as dB (the log base 10 of the value) referenced to a base power level, typically 10-12 watts. It is reported by frequency, typically in octave bands, although sometimes in 1/3 octave bands.

Sound Pressure - The directly measurable fluctuation in pressure,

heard as sound. The sound pressure is reported in dB (the log base 10 of the value), referenced to a pressure 0.0001 microbars. It is reported by frequency, typically in octave bands, although sometimes in 1/3 octave bands.

B44

Space Effect - The calculated attenuation of a space which is different

a moveable damper. They typically have a control device to vary the flow in response to a control signal. In some cases, the term terminals can also mean boxes and GRDs. In those cases, “Boxes” are referred to as Air Control Devices (ACDs). The terminology is inconsistent throughout the industry.

Overview

DESIGN FEATURES PERSONALIZED VAV SYSTEMS

Titus brings both accuracy and flexibility to the variable air volume (VAV) market with T3SQ VAV diffusers. The T3SQ combines the functions of a VAV terminal and a high performance diffuser in one. The T3SQ modulates the air volume delivered to a zone to accurately control cooling and heating conditions. The unique variable geometry design results in maximum air distribution effectiveness at any air flow, for superior comfort conditions. T3SQ adds application flexibility by being able to operate stand-alone with thermal or analog controls. In addition to a superior performance VAV unit, the T3SQ is solidly constructed with 18-gauge steel. Available in many frame styles, the T3SQ can be installed in almost any ceiling as easily as a standard diffuser. The architecturally pleasing design coordinates with any office environment. For applications that require system simplicity, proven technology and superior comfort, specify the Titus T3SQ series of VAV diffusers.

•• Variable geometry diffuser design maintains jet velocity at all flow rates, varying air flow pattern for optimal performance. •• Separate cooling and heating setpoints on thermal T3SQ. •• Supply air temperature provides automatic cooling/ heating changeover on configurations -4 and -2. •• T3SQ-2, digital, can control up to 14 drones. •• Optional electric inlet heater for applications requiring supplemental heat (T3SQ-2 only). •• Provides accurate, personal environmental temperature control to improve productivity in the office environment. •• Superior air distribution performance provides greater entrainment, higher Air Diffusion Performance Index (ADPI) and better ventilation effectiveness for Indoor Air Quality (IAQ). •• Lower cost per zone of control than typical VAV terminal with separate diffusers. •• Renovate existing offices or add zones in problem areas to solve individual comfort problems.

Thermal VAV Diffuser

Supply air temperature sensor provides autochangeover from heating to cooling operation.

DESIGN FEATURES

Easy to turn minimum airflow adjustment ring.

Single piece backpan with multiple border types available to complement various ceiling designs.

Thermal actuator assembly lifts and lowers the control disc producing uniform air pattern in all positions.

Installation and relocation are made easy. •• Constant volume systems can easily become multi-zoned VAV systems, for “big building comfort” on a small building budget. •• Easy and inexpensive to relocate zones, ideal for use where office space may be reconfigured periodically. •• Easy to install and operate. •• Unique center induction on thermal T3SQ-4 ensures accurate readings even at low flows.

Easy to turn heating and cooling setpoint adjustment rings (heating setpoint adjuster only available on heating / cooling units).

Venturi tube and center induction design provide fast and accurate response to changes in zone temperature. A tight horizontal air pattern is achieved by the intelligent curvature design of the backpan.

Face plaque’s curved edge reduces diffuser sound and creates a smooth appearance.

VAV Diffusers

Application Guidelines The Titus T3SQ system is ideal for use with a constant volume system. The T3SQ gives all the advantages of a VAV system at low pressure conditions and reduced installation cost. The T3SQ is a low pressure, pressure dependent, variable air volume (VAV) system. The T3SQ is designed to operate around 0.15â&#x20AC;?- 0.20â&#x20AC;? inlet pressure. This system provides zoned comfort, which is not always possible with a typical constant volume system. 1. It is recommended that a static pressure controller such as the Titus ZECV/ZQCV be installed into a constant volume system when more than 30 percent of the system airflow is put under the control of T3SQ

diffusers. This minimizes the possibility of delivering excess air when a portion of the Zcoms are operating at part load conditions. 2. When an entire constant volume system uses T3SQ zone control, a ZECV/ZQCV box should be implemented. The Titus ZECV/ZQCV pressure control terminal should be sized for 80 percent of the total supply flow, less the airflow of the smallest zone. 3. Care must be taken when sizing and installing a ZECV/ ZQCV. The unit should be installed as far downstream from the fan as is practical to maximize supply and return air mixing. This reduces the risk of the unit cycling on high or low.

Digital VAV Diffuser

MASTER / DRONE T3SQ-2 diffusers are all shipped as drone units. Determination of master units is made through plug and play cable connections to the thermostat. The units connected to the thermostat are the master units. All units daisy chained from the master are drones. Drone diffusers must be connected to a master diffuser in order to operate. One power module is required for every 15 diffusers with or without optional electric reheat. Power module requires 120, 208, 240, 277 VAC line voltage input. The 4-pin mini-fit cables provide 24VAC power and communication between diffusers. This cable should be used between the power module and the first diffuser and also to connect a master unit to a drone unit. Blue RJ-45 8-pin cables provide 24VAC power and control signal between diffusers. RJ-45 cables should be used Master/Drone Wiring

between diffuser and master controller/thermostat and between master and drone units. The Master Communications Module is a central data collection and distribution point for up to 60 VAV field diffusers. The device features four diffuser channel inputs, which can accommodate up to 15 diffusers each. This allows the users to interface with 60 diffusers per communication module through a building management system. The interface software also has a server application which allows all communication modules on site to be accessed through the building management system from the i.p. address of each module. Master communication modules are available in the following communication protocols: • Standard Master Communication module (Stand-Alone) • Master Communications module with Lonworks gateway • Master Communications module with BACnet gateway RJ12 4-pin mini fit cable drone unit

P.S.

One master unit can control up to 14 drone units.

T3SQ-4

Configurations: T3SQ-4

•• The T3SQ-4 is a thermal variable volume diffuser. The diffuser maintains space temperature by varying the volume of air delivered to the space. The amount of air delivered will depend on the Supply Air Temperature (SAT) (-4 only), the room temperature setpoint, and the room temperature. •• Available in heating/cooling (-4) configuration. •• As the volume of air is decreased by the control disc, the velocity of air is increased, thereby maintaining the longest throw and best entrainment. Insuring superior air distribution at all damper positions. •• The curvature of the backpan works with the formed edges of the face panel to deliver a tight horizontal air pattern, without excessive noise or pressure drop over the full range of operation.

•• The T3SQ-4 uses a center induction plug to accurately measure the room temperature. This eliminates the need for a wall mounted thermostat or sensor and provides the most accurate way of measuring the room air temperature. •• Adjustment of the room temperature setpoint is achieved by rotating the blue (cooling) only adjustment ring. •• Adjustment of the green tab offset creates a temperature deadband for heating and cooling setpoints. •• Adjustment of minimum airflow is achieved by rotating the grey minimum airflow adjustment ring. •• Standard finish is #26 White. •• The face panel and backpan are constructed from 18-gauge steel. The formed outer edge also assures a straight and level surface.

VAV Diffusers

PERFORMANCE DATA

The performance of the T3SQ diffuser is related to supply static pressure and size. If the supply static pressure is held at a constant value and the VAV diffuser damper is throttled to a closed position, the airflow pattern is changed from a square pattern to a star pattern. The isovel in the adjacent illustration demonstrates this pattern change. With the

reduction of cfm, throw does not decrease as in standard diffusers. As the damper closes the discharge velocity is slightly increased, minimizing throw reduction. With a fixed inlet pressure, the sound values have very small changes of intensity as the damper is modulated.

Each diffuser shall be electronically controlled by a 24VAC actuator to infinitely vary the supply of cold air into the space by means of regulating a variable aperture damper, known as a control disc, vertically within the diffuser. Supply air from the variable geometry diffusers will discharge horizontally in a 360° pattern and will maintain constant air movement in the space throughout the range of volume variation from 100% down to 25%. The room sensing element shall be located in the master controller/thermostat unit. Each diffuser shall be adjustable to sense room temperature within the space between 65°F and 80°F. In large zones, up to 14 drone units connected to a master unit can be used. Each diffuser shall have an electronic wiring interface having RJ-12 sockets for easy interfacing with master controller/thermostat and 4-pin connection for adjacent parallel master and drone diffusers. Each diffuser shall have a changeover sensor to determine supply air temperature and change the diffuser from heating to cooling operation. The Master Communications Module is a central data collection and distribution point for up to 60 VAV diffusers. The device features four diffuser channel inputs, which can accommodate up to 15 diffusers each. Communication on these channels is by means of a Lin bus interface to four field Power Supply units connected by dedicated communication cables. This centralized data is monitored on a PC running the MLM software Application via an Ethernet TCP/IP interface. The MLM software Application is designed as a commissioning

SUGGESTED SPECIFICATIONS

In addition to the collection and distribution between field diffusers and the MLM Application, the unit also features an on-board web server. This web server can be accessed by a standard browser tool and is used to setup IP addresses, Device identification data as well as communications parameters. In general the web server is used on initial installation to bind to the IP network and to uniquely identify the product, normally by physical location. A serial USB port provides limited diagnostic capability. In general it is used in production to set MAC, IP and port addresses. It can be used to verify and set port and IP addresses. A LON compatible gateway is achieved by adding a plugin hardware module to the MCU. This hardware module contains a subset of the ANSI/CEA-709.1-B (EN14908.1) protocol stack and interface via a TP/FT-10 (Free topology) transceiver network to the device bus. The functional block implementation is indicated in LHA DOC BQ0254-A. Up to 20 of these functional blocks can be selected for a client interface to 20 master control zones. Again the user has the option to use the MLM Application for diffuser setup and diagnostics and the Lon client for general control supervision.

Single Duct Design Features

LEADING THE INDUSTRY: THE TITUS ESV SINGLE DUCT VAV TERMINAL Single duct terminals are the fundamental building blocks for a variable air volume (VAV) system. Their primary function is to regulate airflow to a zone, in response to zone temperature requirements. The Titus ESV is unique as it incorporates many design features that increase performance, decrease installation and service cost and offers increased value, over and above this basic function. All VAV terminals are not equal! By specifying the Titus ESV, you are assured of accurate, AHRI Certified performance ratings. All units are tested, and data shown, in accordance with AHRI Standards. A wide selection of unit configurations, accessories and control types provide considerable scope for problem solving and cost-effective innovation. The ESV’s compact size and easy access for service saves time and expense in installation. The ESV fits easily

in cramped mechanical spaces, either in new building construction or retrofit. Building owners will benefit from the energy efficient low leakage design, reducing utility expenses. Control accuracy, especially at minimum flow rates, is easier to achieve with a Titus multi-point inlet velocity sensor. Control accuracy is critical in maintaining good air quality reducing energy waste. The ESV’s standard insulation is a dual density liner. The skin resists abrasion and erosion from air movement. The body maximizes thermal and acoustical performance. The Titus single blade damper design helps reduce noise levels too, for a quieter work environment.

DESIGN FEATURES

MORE REASONS TO SPECIFY AND SELECT THE TITUS ESV:

Titus innovation carries through the widest array of standard single duct terminal configurations. ETL listed electric coils, manufactured by Titus, are installed, wired and functionally tested as an integral unit before shipment for quicker, trouble-free job-site installation. Multiple outlets with standard locking balancing dampers and integral attenuators are also available.

reinforced surfaces that can be wiped down.

Titus continues to offer the most innovative and popular lining alternatives for special applications including FibreFree; the industry benchmark Steri-Loc; and the premium double wall liner, UltraLoc and EcoShield which is the only natural fiber insulation on the market.

EcoShield is a sustainable liner comprised of recycled denim making it environmentally friendly and contains no harmful irritants or chemicals.

Fibre-Free eliminates the requirement for foil linings and solid inner liners since there is no fiberglass in the airstream. Additionally, Fibre-Free minimizes mold growth since it holds no moisture, is acoustically preferable to foil or solid metal linings and maintains acceptable thermal protection. All of these benefits are available at a competitive price and significantly less than solid metal liners.

With a detailed understanding developed through years of selling and supporting the powerful TD1 digital controller, and now the Titus BACnet OEM controls, Titus has industry leading experience in the application of Direct Digital Control (DDC) to terminals. This same expertise is made available when your project requires quality engineering, coordination and manufacturing for factory mounting when controls are supplied by others.

Steri–Loc provides a smooth, nonporous skin to guard against mold and bacteria growth. Erosion is eliminated, as there is no glass fiber exposure to the airstream. It has

Steri–Loc adds the feature of a very high density, rigid insulation and special “Z-Strip” construction for an extremely rigid terminal. Sound levels are generally superior to dual wall construction, while offering virtually identical levels of protection.

*Factory cfm settings (except zero) will not be made below this range because control accuracy is reduced. On pressure dependent units, minimum cfm is always zero and there is no maximum. Note: On controls mounted by Titus but supplied by others (FMA or Factory Mounting Authorization), these values are guidelines only. Controls mounted on an FMA basis are calibrated in the field.

• Water temperature drop = 2.04 x MBH/gpm. • Connection size is ½-in OD male solder for 1-row coil sizes 04-08. All other coils have ⅞-in OD male solder. • Coils are not intended for steam applications and are labeled for a maximum water temperature of 200°F. • Coils are tested for leakage at test pressure of 500 psi. • Water volumes less than those shown may result in laminar flow and reduced heating capacity. If possible reduce the number of coil rows to increase water velocity into turbulent range.

Single/Dual Duct Terminals

ELECTRIC COILS Recommended Coil Selection Data The table at the right describes the maximum recommended kW capacities and number of stages available for Titus single duct terminals. To make a coil selection: 1. Check the desired kW is available in desired unit size and number of stages. (Required to prevent excessive watt density and current draw, while taking into account unit size limitations.) 2. Check the desired minimum airflow limit is within recommended operating range. (Ensures velocity pressure will be sufficient to close airflow sensing switch.) 3. Multiply desired minimum airflow limit by a factor of 0.0142 and check the result is equal to or greater than desired kW. (Limits temperature rise across the coil to 45°F.) kW ≤ cfm x 0.0142

Titus electric heating coils are specifically designed for use with VAV terminal units. They include an extended plenum section and diffuser plate to minimize stratification. The heating elements are designed to minimize hot spots and nuisance tripping of the thermal cutouts. These requirements established to prevent excessive temperature rise caused by low airflow and/or oversized coils. Minimum airflow limits must be within recommended ranges to ensure proper operation and long service life. For optimum diffuser performance and maximum thermal comfort, coil discharge temperatures should not be more than 15°F above desired room temperatures. For proper coil operation it is recommended that coil discharge temperatures do not to exceed 100°F.

AHRI Directory Of Certified Performance Titus is a charter member company and current participant in the AHRI Directory of Certified Performance. This voluntary certification program was developed by participating manufacturers in conjunction with the former Air-Conditioning and Refrigeration Institute (ARI) in the 1990’s. It is currently administrated by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). The purpose of this program is to provide for the independent verification of manufacturers’ published performance data. Only participating products are authorized to bear the AHRI VAV Certification Mark. Certified data may be viewed and downloaded at www.ahrinet.org . In order to participate in this program, member companies pay annual dues based on sales volume, submit published performance data for all applicable model types, and agree to provide a number of randomly selected product samples for annual rounds of independent testing at the manufacturers’ expense. All verification testing is conducted in accordance with ASHRAE Standard 130 ‘Methods of Testing Air Terminal Units’. These tests are conducted to verify that a manufacturer’s published certified ratings are within the test tolerances outlined in AHRI Standard 880 ‘Performance Rating of Air Terminals’. Any failure to demonstrate the certified performance is punished by additional testing requirements, mandatory performance re-rating, monetary penalties and possible expulsion from the Certified Directory. Product samples provided for certification testing are standard production units with standard ½ in dual density fiberglass lining (unless otherwise specified) and no optional appurtenances such as add-on attenuators or heating/cooling coils. The certified ratings are measured at the standard operating points under the following test conditions:

Single/Dual Duct Terminals

Dual Duct Design Features The concern for IAQ has led to renewed interest in the benefits of dual duct systems. Dual duct systems are an ideal vehicle for alternative ventilation strategies and humidity control. Additionally, total filtration of all air delivered to the zone is possible. Titus dual duct terminals provide high performance and value, making them the preferred selection for these applications. Titus dual duct terminals vary the airflow individually between hot and cold inlets for highly accurate temperature control. As the ratio of hot and cold air is critical in most applications, pressure independent controls are used with a separate velocity control loop to each inlet.

Titus dual duct terminals are available in three styles. In those instances where no blending of airstreams is required, the EDV without the integral attenuator assembly can be an effective choice. When blending of hot and cold supply air is needed for accurate temperature control with minimum flow requirements, the EDV or EDC with integral attenuator should be used. The attenuator reduces discharge sound levels and provides some mixing benefit. An optional mixing baffle is available for use with the attenuator to provide maximum blending of hot and cold airstreams. Less than 1째F temperature variation is provided at the discharge with a 10째F inlet temperature differential!

Additional ductwork is not required downstream to achieve proper mixing, allowing for immediate take-off to diffusers. This is also beneficial for installations with space limitations.

Like the EDV/EDC, the MDV/MDC terminals use separate pressure independent velocity control loops for each inlet, rather than a single velocity controller for discharge volume control only. This provides superior temperature control during blending, as each inlet can compensate for duct pressure changes without affecting the other.

The tightly sealed casing typically allows less than 1 percent leakage of conditioned air to the space at 1.5 inches wg. differential static pressure, making this one of the most energy efficient dual duct terminals. The dampers are the improved Titus low leakage design.

The unique internal mixing baffle design provides for exceptional mixing characteristics. Less than 1째F temperature variation is provided at the discharge with a

All Titus dual duct terminals are also available with EcoShield, Fibre-Free and Steri-Loc lining options. Specify the MDV/MDC and you will be providing the best performing dual duct terminal available.

DESIGN FEATURES

AHRI Directory of Certified Performance Titus is a charter member company and current participant in the AHRI Directory of Certified Performance. This voluntary certification program was developed by participating manufacturers in conjunction with the former Air-Conditioning and Refrigeration Institute (ARI) in the 1990’s. It is currently administrated by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). The purpose of this program is to provide for the independent verification of manufacturers’ published performance data. Only participating products are authorized to bear the AHRI VAV Certification Mark. Certified data may be viewed and downloaded at www.ahrinet.org . In order to participate in this program, member companies pay annual dues based on sales volume, submit published performance data for all applicable model types, and agree to provide a number of randomly selected product samples for annual rounds of independent testing at the manufacturers’ expense. All verification testing is conducted in accordance with ASHRAE Standard 130 ‘Methods of Testing Air Terminal Units’. These tests are conducted to verify that a manufacturer’s published certified ratings are within the test tolerances outlined in AHRI Standard 880 ‘Performance Rating of Air Terminals’. Any failure to demonstrate the certified performance is punished by additional testing requirements, mandatory performance re-rating, monetary penalties and possible expulsion from the Certified Directory. Product samples provided for certification testing are standard production units with standard ½ in dual density fiberglass lining (unless otherwise specified) and no optional appurtenances such as add-on attenuators or heating/cooling coils. The certified ratings are measured at the standard operating points under the following test conditions:

Fan Powered Terminals

APPLICATION GUIDELINES

GENERAL

Fan powered variable air volume (VAV) terminals are a popular choice for heating and cooling perimeter zones. In addition to the inherent VAV economies, fan powered terminals make use of the “free” heat that collects in the ceiling plenum after being emitted by lighting, people, and other equipment. Reasonable first cost, capacity for improved air motion, and low operating costs are additional reasons for the popularity of fan powered VAV terminals. The table, “Summary of Fan Powered Terminal Characteristics” highlights both parallel and series fan terminals.

SUMMARY OF FAN POWERED TERMINAL CHARACTERISTICS FUNCTION

Fan operation and discharge sound are continuous during both heating and cooling.

While both types of fan powered terminals provide VAV energy savings at the central fan, they differ from each other in their inlet static pressure requirements.

Parallel Flow, Fan Powered Terminal Unit Discharge Backdraft Damper Fan/Motor

APPLICATION GUIDELINES

The basic difference in configuration of these terminals is shown in the figures, “Parallel Flow, Fan Powered Terminal” and “Series Flow, Fan Powered Terminal.” In a parallel flow terminal, the fan is outside the primary airstream and runs intermittently, that is, when the primary air is off. In a series flow terminal, the fan is in the primary airstream and runs constantly when the zone is occupied.

SERIES FAN POWERED TERMINALS Constant Volume Fan Powered VAV System

APPLICATION

Either parallel or series flow fan powered terminals can be installed in the ceiling plenum. Each type takes its return air from the ceiling plenum or else has its induction port connected to a duct from the occupied space. Each contains a VAV damper to modulate primary air, plus a fan-and-motor assembly.

CHARACTERISTICS OF PARALLEL AND SERIES FLOW FAN POWERED TERMINALS Select from two basic types of fan powered terminals: • Parallel Flow (Variable Volume) • Series Flow (Constant Volume)

Induced Air Inlet

Primary Air Valve

Fan Powered Terminals

Parallel flow terminals, like non-fan terminals, require enough inlet static pressure to force the air through the primary air damper, casing, downstream ductwork, and diffusers. Typically, the resistance is 0.2 inch wg. for the damper and 0.3 inch wg. for ductwork and diffusers, or a total of 0.5 inch wg. In series flow terminals the fan boosts the air through the discharge duct and diffusers, so the inlet static pressure must only overcome losses through the primary air damper. As a result, the central fan and duct system can be designed for less inlet static pressure, typically 0.1 to 0.2 inch wg.

PARALLEL FLOW TERMINALS

The figure, “Parallel Flow Operation” illustrates the operating sequence of the parallel flow terminal.

APPLICATION GUIDELINES

During full cooling, the controls open the primary air damper for full airflow while the fan is off. As the cooling load decreases, less primary air is delivered to the zone. During this phase the primary air section acts like a nonfan terminal. As cooling demand decreases still further, the fan starts. This boosts air delivery to the zone by inducing warm

As the zone temperature drops further, the thermostat automatically energizes supplemental electric or hot water heating coils (optional equipment on the terminal). The discharge air temperature increases as heat is added. A call for cooling reverses the sequence.

SERIES FLOW TERMINALS

Designers choose series flow terminals for their characteristics of constant air delivery and temperature blending. Nevertheless, these terminals maintain the VAV energy savings at the central fan. Series flow or constant volume terminals are often selected for their acoustical qualities. The sound level is nearly constant as the fan runs continuously (with parallel flow terminals, on-off fan operation can cause noticeable changes in sound levels in the occupied space). Low temperature and ice storage applications capitalize on the temperature blending characteristic of series flow terminals. Models with low temperature liner mix cold supply air with warm plenum air to deliver the required air temperature to the zone. The low supply air temperature permits

Series Flow, Fan Powered Terminal Unit Discharge

Series flow terminals are also selected where it is desirable to maintain a constant cfm, regardless of load. Such areas include lobbies, hallways, restrooms, atriums, and conference rooms. The figure, “Series Flow Operation” shows the operating sequence of the series flow terminal. The terminal fan starts whenever the zone is occupied. It delivers design cfm at all times.Pressure independent controls modulate the primary air damper to maintain the volume called for by the thermostat, regardless of changes in inlet static pressure. As the cooling load decreases, the controls throttle the primary air. The terminal fan makes up the difference by taking more return air from the plenum. This causes the air temperature to vary with the load. At low cooling loads, the primary air damper may close or go to a minimum ventilation setting. As the zone temperature decreases, the zone thermostat energizes stages of optional supplemental heat. The sequence reverses when the load is increased. CAUTION: The series flow fan must be adjusted to handle the maximum primary air volume. If the primary air exceeds the fan cfm, it will spill into the return air plenum and waste energy. The SCR fan speed control provides this adjustment. The minimum voltage stop should be set at 50 percent of rated rpm. Parallel Flow Operation

The primary air damper may be set to some minimum position or else fully closed. The delivered air temperature approaches that of the plenum, taking advantage of heat captured in the plenum from lights, occupants, and equipment.

ACOUSTICS

Series flow terminals may produce a slightly higher overall sound level in the occupied space than do parallel flow terminals. Both the primary air damper and the terminal fan act as sound sources; each generates both discharge (airborne) and radiated sound. Usually, it is the radiated sound that predominates in a room. Radiated fan sound differs between types of terminals because of different air volume requirements. Series flow terminal fans must be sized to deliver design cooling volume, while parallel flow terminal fans can be downsized to deliver a smaller volume, generally 50 to 65 percent of design cooling cfm. As a result, parallel flow terminals normally can have smaller fans with lower sound levels.

SYSTEM CONSIDERATIONS

Series terminal fans should be interlocked to be energized ahead of the central fan to prevent backflow of primary air into the ceiling plenum and to prevent backward rotation of the terminal fan. The interlock can be electrical, by means of an auxiliary contact in the central fan starter for line voltage or a 24 VAC loop for analog electronic controls; pneumatic, using a PE switch; or direct digital, with coordinated start

Series flow terminal fans run during all occupied, and some unoccupied periods, ranging from 3,000 to 4,000 hours annually. Parallel flow terminal fans run during periods of heating and low-load cooling with operating times ranging from 500 to 2,000 hours annually, depending upon the climate and other factors. Series flow terminal fans are selected to deliver design cooling cfm, while parallel flow fans are selected to deliver design heating cfm. Typically, this ranges from 50 to 65 percent of cooling design cfm. For example, a series flow terminal might be selected for 1,000 cfm. A parallel flow terminal fan selected for the same duct system might be selected for 60 percent of this airflow or 600 cfm. Note that the lower airflow requirements will also result in reduced downstream static pressure, falling in this case from 0.55 inch down to 0.20 inch wg. With fewer hours of operation and lower airflow requirements, a parallel flow terminal consumes less energy than a series flow terminal. Series flow fan powered terminals, however, reduce the pressure a central air handler must operate under. With parallel flow fan terminals, the central fan must overcome the terminal damper, downstream duct work, and the diffuser. With series flow fan terminals, the central fan only needs to overcome the terminal damper. The terminal fan addresses the downstream duct work and diffuser. A comparison between the two types of fan powered VAV systems, the energy savings at the central fan must be credited to the series flow fan terminal. The table, Fan Powered Terminal Operating Costs is a comparison of a series flow and parallel flow system.

APPLICATION GUIDELINES

Room noise arising from parallel flow terminals may change with airflow. The intermittent fan operation causes a change in radiated sound as the fan motor starts and stops. This change may be more discernible than a constant sound, even if the constant sound is at a higher level.

An energy consumption analysis should include terminals as well as the central equipment. The energy used by the terminal fan is a function of the operating hours and fan loading. These will vary by terminal type — parallel flow (variable volume) or series flow (constant volume).

This comparison is typical of the “standard” terminals on the market. By using quieter, more efficient series flow terminals such as the Titus DTFS, the system could be designed with larger zones and the same NC. This would lower first costs and narrow (or possibly eliminate) the cost differential between the two systems.

APPLICATION GUIDELINES

ECM MOTOR TECHNOLOGY-THE ULTIMATE IN ENERGY SAVINGS! A substantial energy savings can be realized when using an ECM motor in a series flow fan terminal compared to using conventional induction motors. The ECM motor is an ultrahigh efficiency, brushless DC motor with a unique microprocessor based motor controller. Motor efficiencies of 70 percent or better across the entire operating range of the motor saves considerable electrical energy when compared to conventional induction motors. The motor controller, tuned to a Titus fan powered terminal, provides a large turn down ratio and constant volume airflow regardless of changes in downstream static pressure operating against the fan.

Features and related benefits of the ECM motor in a Titus fan powered terminal are: • 70 percent motor efficiency across the entire operating range of the motor yields substantial electrical savings/payback in less than two years!

• Increased application flexibility due to larger operating range • Unique fan speed control provides simple manual or remote adjustment through the unit direct digital controls (DDC). • Factory preset fan airflows minimize fan terminal balancing efforts.

• Microprocessor based internal motor control maintains constant airflow regardless of changes in downstream static pressure. • Motor operates efficiently down to 300 rpm providing a wide operating range covering most applications.

• Ball bearing design and low heat rise characteristics substantially increase motor life. See the section, Engineering Guidelines and the topic ‘ECM Motors - Fan Powered Terminals’ for additional information. See specific models for ECM performance data.

• Simplify design layout with fewer models to choose from due to increased fan range. Pneumatic, Pressure Independent

• All coil performance in accordance with AHRI 410-2001. • Heating capacities are in MBH. • Data based on 180°F entering water and 65°F entering air. • For temperature differentials other than 115°, multiply MBH by correction factors below. • Head loss is in feet of water. • Always supply water to lowest connection pipe to prevent air entrapment. • Air temperature rise = 927 x MBH/cfm. • Water temperature drop = 2.04 x MBH/gpm. • Connection size is 5/8-in OD male solder. • Coils are not intended for steam applications and are labeled for a maximum water temperature of 200°F. • Coils are tested for leakage at test pressure of 500 psi. • Water volumes less than those shown may result in laminar flow and reduced heating capacity. If possible reduce the number of coil rows to increase water velocity into turbulent range.

PTFS-F, ATFS-F, DTFS-F / WATER COIL HEATING CAPACITY (MBH) • All coil performance in accordance with AHRI 410-2001. • Heating capacities are in MBH. • Data based on 180°F entering water and 65°F entering air. • For temperature differentials other than 115°, multiply MBH by correction factors below. • Head loss is in feet of water. • Always supply water to lowest connection pipe to prevent air entrapment. • Air temperature rise = 927 x MBH/cfm. • Water temperature drop = 2.04 x MBH/gpm. • Connection size is 5/8-in OD male solder. • Coils are not intended for steam applications and are labeled for a maximum water temperature of 200°F. • Coils are tested for leakage at test pressure of 500 psi. • Water volumes less than those shown may result in laminar flow and reduced heating capacity. If possible reduce the number of coil rows to increase water velocity into turbulent range.

Titus is a charter member company and current participant in the AHRI Directory of Certified Performance. This voluntary certification program was developed by participating manufacturers in conjunction with the former Air-Conditioning and Refrigeration Institute (ARI) in the 1990’s. It is currently administrated by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). The purpose of this program is to provide for the independent verification of manufacturers’ published performance data. Only participating products are authorized to bear the AHRI VAV Certification Mark. Certified data may be viewed and downloaded at www.ahrinet.org. In order to participate in this program, member companies pay annual dues based on sales volume, submit published performance data for all applicable model types, and agree to provide a number of randomly selected product samples for annual rounds of independent testing at the manufacturers’ expense. All verification testing is conducted in accordance with ASHRAE Standard 130 ‘Methods of Testing Air Terminal Units’. These tests are conducted to verify that a manufacturer’s published certified ratings are within the test tolerances outlined in AHRI Standard 880 ‘Performance Rating of Air Terminals’. Any failure to demonstrate the certified performance is punished by additional testing requirements, mandatory performance re-rating, monetary penalties and

possible expulsion from the Certified Directory. Product samples provided for certification testing are standard production units with standard ½ in dual density fiberglass lining (unless otherwise specified) and no optional appurtenances such as add-on attenuators or heating/cooling coils. The certified ratings are measured at the standard operating points under the following test conditions:

PTFS, ATFS, DTFS, PTFS-F, ATFS-F, DTFS-F • Rated airflow (cfm) – Based on lesser of an inlet velocity of 2000 fpm or the maximum fan flow with 0.25 in wg of downstream pressure. • Rated fan power (watts) – Based on fan operating at the rated airflow with 0.25 in wg of downstream pressure. • Rated Min ∆Ps (in wg) – Min ∆Ps is the difference between atmospheric pressure and the inlet static pressure at rated airflow with the primary damper full open and the unit fan set to match the primary flow. • Rated ∆Ps (in wg) – A static pressure of 1.5 in wg applied to the inlet duct. • Rated sound power by octave band (dB, re 10-12 watts) – Radiated and discharge sound performance conducted in a reverberation room that meets both the broadband and pure tone qualifications of AHRI Standard 220.

A NOTE ON RADIATED SOUND LEVELS FOR TQS WITH ULTRALOCTM LINER The radiated sound paths for a fan-powered unit start at the fan motor/blower assembly and the primary damper. This sound energy must either exit through the induction port or pass through the casing before reaching the plenum, ceiling tile, occupied space, and eventually the listener. AHRI 885 was developed to provide a standardized way to accurately predict sound levels in a space resulting from noise generated in the ceiling plenum above. It is important to understand that AHRI 885 was formulated to deal with noise from a point source. Terminal units with ‘soft’ liners behave very much like a point source, in that noise is emitted from all external casing surfaces in a roughly equal manner. This is not true for a dual wall unit, where the radiated sound is much more directional. With standard fiberglass and other ‘soft’ liners, sound is emitted from the casing in all directions with slightly more on the side that includes the induction port. Dual wall construction results in a casing with such a high transmission loss that virtually all radiated sounds exit through the induction port. This in effect concentrates and directs the sound energy across the ceiling rather than

Fan Powered Terminals through it, resulting in lower than expected NC levels in the occupied space. Furthermore, the TQS with UltraLoc was carefully engineered to attenuate the second and third octave band frequencies for overall reduced sound levels. Radiated sound power tests were run for all TQS with UltraLoc units in accordance with AHRI 880. The resulting sound power figures make it appear that these units are louder than TQS units with ‘soft’ liners, but mock-up testing has shown lower NC levels. This is due to the fact that all sound generated, regardless of directionality, is measured in a reverberant field. In a mock-up situation, the sound from the induction port is directed into plenum where it is easily attenuated. Although it is difficult to estimate the resulting NC reduction for all unit sizes, it can be as high as 6 NC. AHRI Standard 885 calculations are based upon a ‘point source’ of sound energy. This type of idealized sound source would emit sound energy equally in all directions. While this is very true for single and dual duct terminals and somewhat true for fan-powered units (with other liners), it isn’t true for dual wall fan-powered units. The TQS with UltraLoc liner will have lower actual sound in application than the AHRI 885 NC data shows.

TQS WITH INDOOR AIR QUALITY (IAQ) INLET FEATURES

Building owners are becoming more aware of the health concerns related to poor IAQ. Indoor air is a combination of outside air and indoor air distributed throughout a building. Indoor air pollution is caused by an accumulation of contaminants that primarily come from inside the building. ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality, specifies the minimum ventilation rates and indoor air quality that will be acceptable to human occupants. The standard is intended to minimize the potential for adverse health effects. Standard 62 defines the outdoor air quality acceptable for ventilation, outdoor air treatment when necessary, ventilation rates for residential, commercial, institutional, vehicular, and industrial spaces, the criteria for reduction of outdoor air quantities when recirculated air is treated by contaminant-removal equipment, and the criteria for variable ventilation when the air volume in the space can be used as a reservoir to dilute contaminants.

In January 2000, the Environmental Protection Agency (EPA) released a report on the Energy Costs and IAQ Performance of Ventilation Systems and Controls. The study discusses the benefits (thermal and economic) of the various systems in the three climates, most of these issues will not be discussed in this catalog. The study found that core zones consistently received less outdoor air than the perimeter zones. The core of a building is typically the zone with the largest occupancy levels and therefore would require more outdoor air than the perimeters. Outside air control is typically handled by the central air handling unit. Due to varying conditions in individual zones, the outside air supplied by the air handler may not meet the minimum requirement for the zone. By supplying outside air directly to the zone using the TQS with IAQ inlet, the minimum ventilation requirement for the zone can be maintained.

Titus Offers the Inlet for the TQS. The demand for fresh air inlets on series fan powered terminals has been growing to address the growing IAQ concerns. Titus introduces the IAQ inlet option on the TQS premiere fan powered terminal.

• All coil performance in accordance with AHRI 410-2001. • Heating capacities are in MBH. • Data based on 180°F entering water and 65°F entering air. • For temperature differentials other than 115°, multiply MBH by correction factors below. • Head loss is in feet of water. • Always supply water to lowest connection pipe to prevent air entrapment. • Air temperature rise = 927 x MBH/cfm. • Water temperature drop = 2.04 x MBH/gpm. • Connection size is ½-in OD male solder. • Coils are not intended for steam applications and are labeled for a maximum water temperature of 200°F. • Coils are tested for leakage at test pressure of 500 psi. • Water volumes less than those shown may result in laminar flow and reduced heating capacity. If possible reduce the number of coil rows to increase water velocity into turbulent range.

• All coil performance in accordance with AHRI 410-2001. • Heating capacities are in MBH. • Data based on 180°F entering water and 75°F entering air. • For temperature differentials other than 105°, multiply MBH by correction factors below. • Head loss is in feet of water. • Always supply water to lowest connection pipe to prevent air entrapment. • Air temperature rise = 927 x MBH/cfm. • Water temperature drop = 2.04 x MBH/gpm. • Connection size is 5/8-in OD male solder. • Coils are not intended for steam applications and are labeled for a maximum water temperature of 200°F. • Coils are tested for leakage at test pressure of 500 psi. • Water volumes less than those shown may result in laminar flow and reduced heating capacity. If possible reduce the number of coil rows to increase water velocity into turbulent range.

A DDC system provides many benefits, including lower energy costs, finer temperature control, flexibility, lower maintenance costs and graphical displays of the system. DDC controls have the ability to measure very small increments of airflow and airflow changes, allowing the system to automatically adjust room temperatures. Facility managers and building engineers can easily set and adjust HVAC conditions throughout a building from a central location using a building management system (BMS). There are several protocols for DDC controls. Some DDC controls are proprietary, meaning that they can only communicate with other components supplied by the same manufacturer. Some controls have an open protocol. Typically controls with an open protocol can communicate with components from other manufactures using a gateway, or translator software. Two interoperable control standards, BACnet and LonMark, are increasing in popularity. BACnet is Building Automation Control Network. It is a Communication protocol with agreed upon set of rules for creating interoperable building networks. These rules describe mechanisms for devices (HVAC-R, lighting, fire/smoke, etc.) to share information in a common manner. BACnet is supported by BACnet International which encourages the successful use of BACnet in building automation through testing and has established (BTL) BACnet Testing Laboratory which independently verifies that a product conforms to a listed profile. The standard was developed by ASHRAE, starting in 1987, with the first standard being published in 1995. Standing ASHRAE committee (135) maintains and develop the standard. BACnet is considered an “Open Standard” which allows facility professionals to futureproof their installations allowing multiple product providers. By design, the standard adapts to emerging initiatives. Lonworks is a networking platrom for control-networking systems. It’s interoperable system brings products and solutions together and integrates many system components into one complete solution. Devices in a LonWorks network communicate through a control network specific protocol originally created by Echelon. The protocol was ratified as an official standard by a number of national and international

standards setting bodies. LonMark International (LMI) is an international organization which promotes mulitvendor control systems utilizing the Lonworks standards. The organization inception was in 1994 and it also establishes the interoperable guidelines, provides tools, resources, and support to it’s member and their market There is not one clear solution for interoperability. It is important to note that selecting all BACnet or all LonMark components supplied by different manufacturers does not guaranty easy interoperability. It is important to consider the projects’ specific requirements and make an educated decision about the DDC controller that is best suited for the building and owner’s needs. Titus offers several options for DDC controls to suit the variety of communication protocols on the market to be installed on Titus terminal units.

Direct Acting

There are still more benefits: The Titus II controller is the ideal choice for new construction, retrofit applications, or replacement. Consider these features: •• Accurate control over a duct velocity range of 0 to 3000 fpm. •• Operates at low system pressures. As effective at 0.03 inch Ps as at 6.0 inch Ps. •• Pressure independent. •• Reset span remains constant regardless of maximum and minimum cfm adjustments. The factory set 5 psi span is adjustable from 3 to10 psi to match any thermostat. •• Reset start point is adjustable from 3 to 13 psi to work with accessories such as reheat coils (factory setting is 8 psi). •• Thermostat switch changes the action from direct acting to reverse acting without additional calibration. No additional relays required— great for quick retrofit installation!

•• Damper switch changes the operation of the control from normally open to normally closed without re-calibration. No additional relays required. •• All adjustments are made with a hex shanked knob stored in the face of the Titus II controller. •• Operates on a control air pressure of 15 to 25 psi. •• Control air consumption is no more than 1.2 scfh. The Titus I controller is also available for applications less demanding than those where the Titus ll controller is required, the economical Titus I can be furnished.

In operation, the Titus amplifying velocity sensor in the inlet feeds signals to the Titus II controller, which acts as a pneumatic computer. As indicated by the block diagram, the controller monitors the input data â&#x20AC;&#x201D; room temperature, system total pressure, static pressure, and velocity pressure. It processes the input data and energizes the pneumatic damper actuator to obtain the required airflow. The results of the damper movement are sent as pressure signals through the feedback loop to the input for evaluation and correction.

Because of the extreme sensitivity of the controls, minor variations in the room temperature and duct pressure are immediately sensed and acted upon. Hunting and over controlling are minimized and operation is stable over the entire operating range.

Titus II Block Diagram Feedback

PRESSURE DEPENDENT (SINGLE DUCT TERMINALS) In pressure dependent terminals, the sensor and controller are omitted and the pneumatic actuator is controlled directly by the thermostat. This version of the Titus pneumatic terminal unit is used where neither pressure independence nor regulated maximum flow is required. An example is a variable volume air supply in which the duct pressure is held constant by other controls.

All velocity controllers are not equal! The Titus II has offered unequaled pneumatic velocity reset control for more than 20 years. While there are some claims of equality, no control better suits the needs of today’s new construction, retrofit, or replacement market for pneumatic controls than the Titus II. The table to the right compares the Titus II with two other controls on the market today. The Titus II is clearly superior!

The reset span can be adjusted from 3 to10 psi (5 psi is standard). It is then held constant, even if the cfm settings are changed. The reset start point is also adjustable to match various thermostat throttling ranges such as 3 to 8, 5 to 10, or 8 to 13, and to coordinate with accessories such as heating coils.

CONTACTOR CIRCUITRY

De-Energizing Type

There are two types of contactor circuitry used in electric coils: de-energizing contactors break only one ungrounded line on single phase circuits and two ungrounded lines of three phase circuits (Note: Breaking the L1 on 277 volt electric coil can be considered as disconnecting.) Disconnecting contactors break all ungrounded lines or conductors. The electric coils are wired for deenergizing contactor circuitry as standard.

ELEMENT WIRING CONFIGURATIONS There are three basic wiring configurations used with electric coils. The coil can be wired for single phase, three phase delta, or three phase wye. When using single phase coils versus three phase coils, the amp draw will be almost double and will require heavier gauge conductors.

Therefore, it would normally be more economical to use three phase electric coils. If the electric coil and fan motor combination exceeds 48 amps, you are required to subdivide the heating elements. Each subdivided circuit will be required to have some type of over current protection such as fuses. Note: A 480 volt three wire wye connection, 277 volts is not available for the fan motor. You must have four wire wye.

The zone reheat in an HVAC system needs to address concerns about comfort, indoor air quality, energy and acoustics. Several ASHRAE Standards are used to cover all of these areas of design. The ASHRAE Fundamentals Handbook states that discharging air at a temperature more than 15°F above the room (90°F in a 75°F room) will likely result in significant unwanted air temperature stratification. ASHRAE Standard 62 (Indoor Air Quality) has been modified to require increased outside air when heating from the ceiling (Table 6.2, Addenda N. Using the ASHRAE 129 test procedure for Air Change Effectiveness, mixing effectiveness values as low as 20% (or lower) have been observed, when the supply to room differential exceeds 15BF. In most cases, it only requires 85BF air to handle a typical winter design perimeter load at 1 cfm/Sq.Ft. air supply rate (the airflow rate recommended for both good ventilation mixing and comfort). Standard staged electric heat energizes each stage of heat as the zone temperature calls for more heat. In a threestage heater, the increase happens in 33% heater output increments. If an additional 33% heater output provides too much heating, then the heater will de-energize that stage. The result is over- and under-heating of the zone. A proportional SCR or SSR heater eliminates the over- and under-heating of the zone by providing only as much heater output needed to satisfy the zone.

silent, rapid responding solid-state relays. The solid-state relays are controlled by the Lynergy Comfort Controller. The Lynergy Comfort Controller is available in 208V and 240V single phase and 277V, 208V, and 480V three phase line voltages. The Lynergy Comfort Controller accepts one of seven input signal types to provide superior control and flexibility: PWM, 2 stage heat, 0-10V/0-20mA, 2-10V/420mA, Incremental thermostat, binary, and 3-point floating. If the optional discharge temperature sensor is used, the heater is set to modulate heat to a set discharge temperature. The sensor can be mounted up to 20 feet from the unit discharge. User defined maximum temperature and controller defined temperature desired are maintained independent of heater kW or incoming air temperature. The maximum discharge temperature produced by the heater is set by rotary dial on the Lynergy control board. When the unit receives a signal to start heating, the board will take an initial temperature reading and modulate heat from that point to the maximum temperature. For example, if a thermostat requires only a 10% increase in heating of air that was initially 60°F, and has a maximum temperature setting of 90°F, the Lynergy controller will modulate the heater’s output temperature to 63°F (the additional 3 degrees coming from (90°-60°) x 10%). This option allows an increase of heater energy into occupancy by increasing discharge airflow while keeping an optimal discharge temperature.

Standard staged electric heat typically uses magnetic contactors to energize the stages of heat. Due to acoustic requirements in many building designs, engineers often specify mercury contactors for silent operation. Mercury contactors significantly increase the cost of the heater.

An SCR controller is a time proportioned controller that modulates the heater to supply the exact amount of heat required to satisfy the zone requirements. SCR electric heat works by modulating the time the electric heater is powered on, not the kW of the heater.

There are also growing environmental concerns about the use of mercury in buildings. Many building components contain mercury and, in the component’s application, pose little risk to the environment, but the potential for a spill is always present. For this reason, some local codes require registration of mercury devices, and careful controlled disposal. Because of this, many engineers are limiting the use of mercury contactors.

An SCR heater sends a pulsed ON/OFF signal to energize and de-energize the electric coil to provide an average heat output that matches the heat requirement of the zone. The SCR is silent and can be pulsed continuously. The Titus SCR controlled heater has a patented proportional electronic airflow sensor. This sensor allows the heater to operate at extremely low airflow. The unique electronic flow sensor allows the heater to respond exactly to the quantity of air flowing through the unit and safely de-energize in case of a total loss of airflow. The electronic airflow sensor allows you to size the box for the exact space requirements instead of oversizing for minimum required heater cfm, which can reduce the initial terminal unit cost.

LYNERGY

During the time a standard staged electric heater is overheating the zone, it is using more energy than needed to satisfy the zone. For example, if the zone requires 50% of the heater capacity, a three-stage heater would have to output 66% of its capacity until the thermostat responds to the temperature in the over-heated zone and de-energizes the second stage of heat.

The Lynergy Comfort Control SSR electric heater is an electronic, time proportional electric heater, which utilizes

OPTIONAL STANDARD SCR CONTROLLED ELECTRIC HEAT

As an alternative to the standard staged electric heater, Titus offers SCR controlled electric heat, also known as time proportioned electric heat. SCR controlled electric heat provide superior comfort and energy savings.Two and three stage electric heaters cycle the stages on and off to meet the comfort requirements of the space. When the zone requires 50 percent heat output, a three stage heater will cycle the second stage of heat on and off. When the second stage is on, the heat output is 66.6 percent, 16.6 percent more than required to satisfy the zone.

The solid-state relays, used in SSR heaters, address the acoustic concern of using magnetic contactors and the environmental concern of mercury contactors.

VAV Retrofit Terminals

Overview - External Round Duct Series Titus External Round Retrofit Terminals can upgrade those old existing HVAC systems to current standards of energy efficiency and comfort! External round retrofit terminals are designed to easily convert the old system powered or constant volume systems to more energy efficient variable volume systems. They may also be used in newly designed systems as air measuring devices and exhaust control valves. With Titus external round retrofit terminals, you never have to worry about a lengthy conversion process. Compact and light weight, these units install quickly in cramped spaces, supported only by the existing ductwork. The simple Multiple rolled beads on the casing ensure roundness, while providing the benefit of leak free connections to round ducts.

cylindrical casing matches standard round duct at both inlet and outlet. ECV Series and PECX units can be inserted in branch ducts where no control units have been before. They may also be used to replace older units or added to the inlets of existing units that are entirely or partly deactivated. The ECV Series terminals are available from Titus with pneumatic, electric, analog electronic or direct digital controls (DDCs). Flexibility in application makes selecting Titus external round terminals the simple solution for any retrofit project.

Field convertible linkage (pneumatic controls) allows NO/NC changever without actuator removal.

Both ends are sized to allow easy insertion into standard hard or flexible round ducts.

Stainless steel casing is available for use in areas where hazardous envrionments exist.

AeroCross™ multi-point, center averaging sensor amplifies flow signal and ensures control accuracy, regardless of inlet duct configuration.

Unit now provides pressure independent variable air volume, cooling (or heating) only, regardless of whether existing thermostat is direct acting or reverse acting, or whether damper is normally open or normally closed.

EXISTING PNEUMATIC DUAL DUCT: CONVERTING TO DUAL DUCT VAV; TWO EXISTING DAMPER ACTUATORS (Option 1)

Existing constant volume regulators are retained and used. Cooling inlet is left as is. PECX is installed on heating inlet. Existing room thermostat is connected to both existing cooling damper actuator and to the Titus controller on the PECX, which controls existing heating damper actuator. This conversion provides variable air volume without wasteful simultaneous heating and cooling. Heating control is pressure independent; cooling is pressure dependent. Maximum cooling cfm is limited by existing constant volume regulators. Maximum heating cfm (less than cooling) is limited by adjustment of PECX. A mixing minimum airflow can be obtained with a start point adjustment using the Titus II Controller.

APPLICATIONS

(Option 2)

For pressure independent control of both heating and cooling, constant volume regulators are deactivated or removed. PECXs are installed on both heating and cooling inlets. Existing room thermostat is connected to Titus controllers on both PECXs, which control both existing damper actuators. A mixing minimum airflow can be obtained with a start point adjustment using the Titus II Controller.

Overview - QCV Slide-In Series

FEATURES AND BENEFITS Titus Slide-In Retrofit Terminals convert those old constant volume systems to modern and energy efficient variable air volume. Slide-in retrofit terminals are designed to transform inefficient constant volume systems to present day variable volume systems with very low installation costs. The resulting performance of a system incorporating Titus QCV series terminals approaches that of a VAV system using ESV

Available in many different sizes, the QCV series units will mount in almost any square size duct.

Field convertible linkage (pneumatic controls) allows NO/NC changeover without actuator removal. The casing can be configured to mount on either the right side or left side of the existing duct.

Elastomer seals on the edges of the damper blades allow low leakage during full shut off.

SLIDE-IN SERIES

Take a look at many of the unique features of a Titus QCV series retrofit terminal!

Damper position indicator is formed into the end of the shaft for easy monitoring of damper position.

AeroCrossTM multi-point, center averaging sensor amplifies flow signal for best control of low flow rates. Center averaging feature provides signal accuracy, regardlessof inlet duct configuration.

Shown here with the TITUS I pneumatic velocity controller, the QCV is also available with analog electronic and direct digital electronic controls.

Damper is constructed of 16-gauge galvanized steel to prevent vibrationunder high pressure conditions.

series single duct terminals. With the simple installation method, conversion costs are minimized. The installer simply cuts a rectangular hole in the side of the duct, cuts away the insulation (if present), slides the unit into the duct, and screws the mounting plate to the side of the duct.

PQCV

Formed flanges provide added duct stiffness at the insertion point.

APPLICATIONS

On a rise in room temperature, the PQCV reduces the hot airflow. At the minimum airflow setting, the damper in the existing unit, which in this example has an 8 to 13 psi actuator, begins to modulate and mixing occurs. A further temperature rise increases the cold airflow to the maximum. Since the total air volume is reduced, the fan may need to be slowed down.

N. Open N. Closed

TITUS PQCV with ECT-3LD Control Kit

DUAL DUCT SYSTEM

The mechanical constant volume regulator is removed from each existing terminal, while a QCV is installed in the discharge duct. A direct acting thermostat controls both the PQCV and the modulating splitter damper in the existing terminal.

cfm Increase

The multi-zone dampers provide a mixed airflow temperature of air at minimum airflow. The PQCV valves provide VAV and pressure independent flow. Very little work is required to convert a multi-zone pressure dependent set of zones to an energy saving series of VAV zones. Each zone now has fixed maximum and minimum airflow without system hunting.

MULTI-ZONE SYSTEM

Hot or cold air from the central multizone air handler is distributed through the original zone ducts. The QCV retrofit terminals convert the system to variable air volume operation.

low

Each QCV terminal is signaled by a direct acting thermostat. In the pneumatic example shown in the diagram, the pressure independent minimum airflow is set at a thermostat output pressure of 8 psi or less, while the maximum is set at 13 psi or greater. The existing reheat coil in each zone is actuated on a fall in room temperature as the thermostat output decreases from 8 to 3 psi.

VAV Retrofit Terminals

FEATURES AND BENEFITS Titus Internal Retrofit Terminals convert those old mechanically regulated terminals to energy efficient VAV terminals!

ECT valves, the inefficient constant volume system is transformed into an energy saving, comfort providing variable volume system.

Existing constant volume systems retrofitted to variable air volume conserve energy by reducing reheat requirements, reducing refrigeration loads and reducing fan horsepower by taking advantage of building load diversity. Titus provides an easy, effective means to retrofit existing mechanical constant volume terminals without replacing the existing terminal or interrupting ductwork.

Mechanically regulated terminals were produced by many different manufacturers over the years, including Titus. Today, a different model of ECT series retrofit variable air volume valve is used to replace the old mechanical regulators for each different manufacturer of terminals. Best of all, this is done with very little effort since each retrofit valve is designed to be installed while the supply air system is still running and without removing the existing terminals.

Titus internally mounted, or ECT series, terminals are the most unique line of retrofit devices in the HVAC industry. Specifically designed to quickly replace mechanical regulators in existing terminals, each ECT series valve is unique. By replacing the mechanical regulators with

Each ECT series valve is designed for maximum efficiency in operation and installation. Letâ&#x20AC;&#x2122;s look at some of the features found in Titus ECT series internal retrofit terminals.

AeroCrossTM multi-point, centeraveraging sensor amplifies flow signal for best control of low flow rates. Center-averaging feature provides signal accuracy, regardless of inlet duct configuration.

All ECT series terminals are designed to be installed through existing access panels so no extensive sheet metal rework is required. Heavy gauge galvanized steel construction ensures quiet and durable operation. ECT-AN

SPECIAL PURPOSE & INTERNAL

Retrofit valve damper is normally open for ease of installation with supply air system operating. DelrinÂŽ damper bearings are unaffected by temperature and humidity, and prevent binding. ECT-KR

ECT-L series control packages, in conjunction with ECT series valves, can operate virtually any kind of control sequence.

Multiple ECT series valves can be operated from one ECT-L series control package.

All control components found in an ECT-L series control package are protected by a heavy gauge metal enclosure.

In the preceding diagram, the addition of a reversing relay and a high pressure selector allows pressure independent VAV control of heating, as well as cooling, in the dual duct unit. In this example the reversing relay bias is set at 10.5 psi. The Titus ECT-3LD is set for minimum cooling cfm at 13 psi thermostat output pressure. From 13 to 8 psi the original dual duct unit damper modulates from cooling to heating, so that there is mixing at the minimum cfm. From 8 to 3 psi the Titus control modulates from minimum to maximum heating cfm. The Titus II start point is adjusted to 13 psi.

Here both the reversing relay bias and the ECT-4LD start point are set at 8 psi. The ECT-4LD is also set for a minimum cfm of zero. The original dual duct unit damper snaps from 100 percent cooling to 100 percent heating at 8 psi. Below 8 psi this damper remains in full heating position, while the Titus control modulates from minimum to maximum heating cfm.

ECT-AN

Available Model: ECT-AN • HV-C series only Constant Volume* Options E, D, O or R • Dual Duct or Single Duct Applications

ECT-AN is a variable air volume, retrofit control valve. Designed for retrofitting Anemostat mechanically controlled terminals, it directly replaces the mechanical constant volume regulators. This change out is easily done through the access panel in the bottom of the existing Anemostat terminal. The Titus ECT-AN valve fits the same space as the original volume regulator. The mounting holes in the ECT-AN inlet panel are prepunched to fit the existing bolts. While most Anemostat terminals will require no additional modifications, exceptions may be encountered because of minor variations in original manufacture. Simple relocation of the mounting holes, the valves or the sound/mixing baffle may be necessary to overcome space limitations.

SELECTION GUIDE The table shows the number of original mechanical regulators in each Anemostat terminal size. It also

shows the corresponding sizes of Titus ECT-AN valves needed to replace these regulators. Each cfm range is the total for the entire terminal. The ECTAN cfm range represents the typical limit settings for the reset span of a pneumatic velocity controller. The minimum should be equal to or greater than 50 percent of the maximum airflow setting. The ECT-AN retrofit valve can be adjusted for a minimum cfm setting of zero (full shutoff). The ECT-AN retrofit is also available with electric actuators for use with electronic or DDC retrofit controls. Before the retrofit valves and controls are ordered, Titus recommends spot checking the existing terminals to determine the condition of the inlet dampers and actuators. The interiors should also be checked for space limitations and mounting conflicts.

ECT-BC

www.titus-hvac.com | www.titus-energysolutions.com

Special Purpose & Internal Series (continued)

ECT-BC is a variable air volume, retrofit control valve. Designed for retrofitting Barber-Colman mechanically controlled terminals, it directly replaces the mechanical constant volume regulators. This change out is easily done by removing the existing mechanical regulator from the side mounting channels and installing the new Titus ECT-BC valve in the same channels. The resulting performance approaches that of the current Titus Model ESV for single duct operation and EDV for dual duct operation. The hand of the ECT-BC retrofit valve can be changed by inverting it before sliding it in place. If using pneumatic velocity controllers as illustrated, simply snap the controller back into its bracket to maintain a dials-down orientation.

SELECTION GUIDE The table shows the retrofit valve size for each size of Barber-Colman terminal, together with the selection range for maximum airflow (retrofitted).

ECT-BU

Available Model: ECT-BU • H-Series, Designs 14 and 16

ECT-BU is a variable air volume, retrofit control valve. Designed for retrofitting Buensod design 14 and 16 mechanically controlled terminals. It directly replaces the mechanical constant volume regulators. This change out is easily done through the access panel in the bottom of the existing Buensod terminal.

Each cfm range is the total for the entire terminal. The ECTBU cfm range represents the typical limit settings for the reset span of a pneumatic velocity controller. The minimum should be equal to or greater than 50 percent of the maximum airflow setting.

The old regulator flange is used as a pattern for drilling the mounting holes in the ECT-BU inlet panel. While most design 14 and 16 terminals will require no additional modifications, exceptions may be encountered because of minor variations in original manufacture. Simple relocations of the valves or of the sound baffle may be necessary to overcome space limitations.

SELECTION GUIDE The table shows the number of original mechanical regulators in each Buensod terminal size. It also shows the corresponding sizes of Titus ECT-BU valves needed to replace these regulators.

The ECT-BU retrofit valve can be adjusted for a minimum cfm setting of zero (full shut-off) with leakage less than 10 cfm at 3 inches pressure differential. The ECT-BU is also available with electric actuators for use with electronic or DDC retrofit controls. Before the retrofit valves and controls are ordered, we recommend spot checking the existing terminals to determine the condition of the inlet dampers and actuators. The interiors should also be checked for space limitations and mounting conflicts.

Overview

BYPASS TERMINALS FEATURES AND BENEFITS PRESSURE CONTROL TERMINALS Whether yours is a new system or retrofit of an existing system, the ZECV and ZQCV bypass terminals are excellent choices for pressure control. Both the ZECV and ZQCV can be can be applied in either bypass or branch pressure control situations, with quick installation and setup. They are ideal for use in systems when constant volume supply fans are used with variable volume control. Bypass pressure control is essential to prevent excess air delivery to uncontrolled zones in systems that are partially variable volume (when some zones have volume control and others do not). Discharge pressure control can be used to

increase the effectiveness of dampers or diffusers used to control air delivery to zones, as well as to decrease sound levels in zones. The standard electronic control package includes a pressure transducer with remote static pressure tap (for field installation), an electronic actuator and adjustable control module, installed in a NEMA1 enclosure. The control module can be located remotely for easier access. Control voltage is 24 VAC; optional transformers are available mounted and wired in primary voltages from 24 to 480 VAC to match building power.

Bypass Terminals (continued)

HOW TO APPLY THE ZECV / ZQCV PRESSURE CONTROL TERMINALS Bypass terminals should be used whenever VAV control devices handle more than 30 percent of the total airflow on a constant volume system. Dependent upon application, a bypass terminal can minimize the possibility of delivering excess air to uncontrolled zones, or can significantly improve the performance of controlled zones by increasing modulation capability and decreasing sound levels. In Bypass Pressure Control applications, the ZECV or ZQCV relieves system pressure by opening to a return duct or ceiling plenum. The field installed static pressure tap (provided by Titus) is installed in the supply ductwork to sense system static pressure. When used for Bypass Pressure Control, the terminal should be sized to handle 80 percent of the total supply flow, less the airflow of the smallest controlled zone. A schematic of a bypass pressure control application appears below. Care must be taken when installing the bypass damper. It should be installed as far downstream from the fan intake as is practical to maximize supply and return air mixing. This reduces the risk of unit cycling on high or low temperature limits. When using rooftop units with outside air economizer cycles, special attention must be given to building pressurization. Maintaining a slight positive building pressure is preferred;

Bypass Pressure Control Application

however, in light cooling situations when an economizer opens fully to supply outside air, the possibility of building over-pressurization exists. When this occurs, more air is entering the building than can be exhausted. This can result in reduced airflow to the zones, as well as entry doors that whistle or stand open. An effective method of addressing this situation is an additional exhaust fan sequenced to energize whenever the outside air damper opens beyond minimum position. This will ensure the building receives the advantages of outside air supply while maintaining excellent comfort conditions. Discharge Pressure Control applications often involve the addition of a number of VAV devices on a constant volume system where it is necessary to reduce pressure to the inlets. The ZECV/ZQCV relieves individual branch pressure by closing to increase pressure drop to the VAV devices. The static pressure tap would be installed downstream of the bypass terminal to sense individual branch static pressure. A schematic of a discharge pressure control application appears below.

When used for Discharge Pressure Control, the terminal should be sized to handle the maximum calculated flow requirement of that branch.

BYPASS / PRESSURE TERMINAL RECTANGULAR DUCT Available Model: ZQCV ZQCV

• Limits static pressure in duct systems feeding VAV devices. • Standard analog electronic controls. • Easy, low cost installation into rectangular duct. The installer simply cuts a rectangular hole in the side of the duct, cuts away the insulation (where present), slides the unit into the duct and screws the mounting plate to the side of the duct. Reinforcing angles are screwed to the top and bottom edges (see the illustration below). • In bypass pressure control application the static pressure tap must be installed downstream of the terminal. Pressure is relieved by opening the damper to the return duct or plenum. • In discharge pressure control applications, the static pressure tap must be installed downstream of the terminal. Pressure is relieved by closing the damper to increase the pressure drop to the VAV devices.

• Damper is constructed of 16-gauge galvanized steel. • Maximum static pressure setpoint is adjusted at control module inside control enclosure. • Tight close-off damper. Leakage is less than 2 percent of nominal cfm at 6-inch sp wg. • Gaskets under the mounting plate and at the end of the orifice plate seal the unit to the sides of the duct (see the illustration below). • The hand of the terminal can be changed by flipping unit upside down. It is not position sensitive.

APPLICATION GUIDE

General This document provides application and design highlights for underfloor air distribution (UFAD) systems. Additional information may be found at the Titus website. www.titus-hvac.com

Introduction The interest in underfloor air distribution (UFAD) has increased significantly in the U.S. market over the last fifteen years. There is currently several million square feet of access floor air distribution systems being designed across the country. In 1997 Titus introduced the TAF-R diffuser and the TAF-G grommet, which were installed in the Owens Corning World Headquarters. Since then, Titus, ASHRAE, and the engineering community have continued to learn about UFAD systems. In the time that Titus has participated in UFAD designs in the US, we have continued to introduce new products to meet the needs of this unique application.

APPLICATION GUIDE

Overview

ASHRAE Applications Handbook (2011) describes Underfloor Air Distribution Systems (UFAD) as Partially Mixed Air Distribution. Where traditional ceiling or high sidewall supply outlets condition the space by creating a thermal mixing zone from the floor (ankle level) to near the ceiling, Underfloor systems create a mixed zone from the floor to the top of the occupied zone (6’ above the floor), and let the upper zone be fully stratified. The height of the mixed zone is controlled by the height of the air jet to a velocity of 50 fpm. The ideal throw height of the jet is to 4’ – 5’ above the floor. Contaminates above the mixed zone will rise through the stratified zone and be carried out of the room through the return. Where a fully mixed system uses the area within one foot of the interior walls as a mixing zone, a floor outlet uses the area around the outlet where mixed air velocities are greater than 50 fpm. Floor outlets used in the interior area (more than 12’-15’ from a perimeter wall) are typically round producing a swirl air pattern. The mixing zone, typically known as the “clear” zone is defined by the manufacturer. It is recommended that occupants not be permanently stationed in the clear zone. UFAD systems utilize the space under an access

UnderFloor Air Distribution floor as an air plenum. Properly designed UFAD systems take advantage of thermal stratification. ASHRAE recommends that, for comfort, the temperature in the occupied zone be between 73B and 77BF, relative humidity be between less than 60%, and the maximum velocity in occupied zone be 50 fpm in cooling or 30 fpm in heating. The key to successful access floor systems is the ability of the access floor diffuser to rapidly mix room air into the supply air at low velocities. Because supply air is introduced directly into the occupied zone, it is important that the supply air reach the ASHRAE recommended temperature and velocity, mixing of the supply air into the space should happen rapidly. The typical application for a UFAD system is the open plan office. Floor space is at a premium in a cubicle so a smaller clear area around the diffuser will allow more usable space in the cubicle. The UFAD diffuser manufacturer defines the required clear area that their diffuser needs to achieve the ASHRAE recommended temperature and velocity. Originally UFAD systems were for computer rooms. The design intent was to cool computer equipment and not to provide comfort. The computer room design concept typically provides too cold of a space for comfort. There has been a growth of UFAD systems used in offices and headquarters in U.S. It is estimated that 10% of U.S. construction will utilize access floors within few years. While the early interest in UFAD systems was primarily due to companies’ need to easily rearrange office layouts, information and communications based offices, the economics of ownership, and green building programs such as LEED have largely influenced the growth of UFAD in recent years.

DESIGN BASICS PLENUM DESIGN The raised floor office can be supplied with conditioned air from below the floor in two ways – pressurized plenum or neutral plenum.

PRESSURIZED PLENUMS The pressurized plenum (the area between the slab and the raised floor) is essentially a large duct maintained at a constant pressure differential to the room above; typically between 0.05 and 0.10 in. pressure (w.g.). This pressure is maintained through the supply of conditioned air from a number of supply duct terminations. The spacing and location of these ducts are dependent on the air supply requirement and the plenum depth, with shallow plenums and / or high air quantities requiring more air supply duct outlets under the floor. UFAD diffusers are specially designed grilles with a user adjustable damper to regulate flow.

NEUTRAL PLENUMS With the neutral plenum design, the same layout as the pressurized plenum may be used, but the pressure difference between the plenum and the room is kept as close as possible to zero. Floor diffusers either contain integral fans, are ducted from a central source, or both. In many cases, these closely resemble conventional ceiling supply systems.

This design is rarely used, but may be effective in tenant buildings where the utilities will be paid by the tenant.

PLENUM DETAILS Plenum heights typically range from 14” to 18”, occasionally going as low as 12” or as high as 24”. The plenum height is usually determined by the height requirements of other equipment that will be located under the floor. The number of inlets required to supply the plenum with sufficient air to run the diffusers is dependent upon the plenum size and the number of diffusers, which in turn is determined by the load of the space. As a general rule, the longest distance from the supply air outlet in the plenum and the farthest diffuser should not exceed 35 feet. Distances longer then this are subject to thermal losses created by thermal conductivity of the return air from the floor below through the slab making the discharge temperature of the diffuser be too high. Duct runs in the plenum space known as air highways can be used to transport conditioned air from the main duct to the zone. If zone control is desired from the underfloor plenum, the plenum can be partitioned into separate zones. The zones in the underfloor plenum should correspond to building zones having similar load requirements. However, it is not necessary to partition the underfloor plenum into zones and doing so can make future office layout changes more difficult. If an office layout must be changed, the partitioned

APPLICATION GUIDE

The advantages of pressurized plenums include low first cost and easily changed layouts. This is the most commonly used plenum design.

Advantages include the possibility of multiple small zones (as with multiple tenants) and insensitivity to construction details. Disadvantages include higher first costs due to ducting and/or fan connections under the floor, lower flexibility as the grilles are individually ducted, and potentially higher noise levels.

plenum will need to be changed to match the new layout. Because of the special heating and cooling requirements of the perimeter of the building, it may be necessary to create a perimeter zone in the underfloor plenum to run a separate perimeter system. Typically only the perimeter is zoned from the core. The perimeter will be discussed in more detail next.

PLENUM LEAKAGE Sealing the underfloor plenum is critical to optimizing the operation of a UFAD system. Air leaking through the floor tiles into the occupied zone is of minimal concern because it is leaking into the occupied space. Air leaking into the space between the walls, however, is wasted energy. All knockouts and holes in the drywall below the raised floor must be sealed during construction.

More important is eliminating the leakage that occurs from the plenum through apertures into the vertical walls. Care should be taken to inspect and seal all openings into the walls where electrical, plumbing, or other items may pass from the plenum into the wall. Air leakage through these passages will result in loss of conditioned air that will never pass through the occupied zone. Inspecting these areas during the construction process when they are accessible can eliminate costly repairs during commissioning.

Open plan interior spaces are typically conditioned by placing a round swirl outlet at or near the entrance open to the cubicle or individuals work area. This will allow the cool jet to condition the adjacent space. Individually adjustable outlet dampers allow the occupant to control the comfort in their work zone. Larger common areas can be controlled with a single thermostat operating motorized dampers on multiple outlets.

While leakage through the floor tile seams into the occupied space is less critical it should not be ignored. Floor leakage can be minimized by applying a gasket between the floor tile and the support stringer. Securing the tile to the structure with bolts will help create a tight seal. Additional floor sealing can be achieved by lapping the floor carpet tile over the tile seams.

The perimeter is typically the most difficult area of an underfloor system to design. The perimeter is often handling much larger loads and requires the most equipment. In the past, the best way to handle the perimeter was to use fan powered terminals with reheat ducted to linear bar grilles. There are a couple challenges with this design concept. The throw of a linear bar grille ducted to the discharge of a fan powered terminal is very long, possibly as long as 15-20 feet. Designing long throws at the perimeter contradicts the

The TAF-L perimeter system provides this ideal air pattern. The TAF-L system consists of a modular cooling plenum, the TAF-L-V, and heating plenum, the TAF-L-W, designed to be integrated with the CT-TAF-L multi-deflection linear bar diffuser.

Additional challenges on the perimeter may be caused by the radiation effect of the sun shining through the glass and warming the first four to six feet of the plenum and slab beneath the floor. Thermal conduction through the outer wall into the plenum may affect the conditioned plenum air in the perimeter area as well. Applying a spray on thermal coating or other insulation material to the wall and floor of the plenum perimeter can prevent infiltration and minimize these thermal losses. Materials that harbor mold or bacteria growth should be avoided. Although the concept of UFAD systems is to be modular, the function of handling perimeter loads is not modular. Those loads come with the building envelope, which is always a line of some sort. The TAF-L Perimeter System was designed to address all of these considerations.

PERIMETER COOLING The perimeter cooling system should combine induction, buoyancy and displacement ventilation models, handles high thermal loads such as 225 CFM per 4â&#x20AC;&#x2122; length at 0.07â&#x20AC;? wg, engage the occupied zone, but not the stratified ceiling layer. This avoids occupant complaints from air rolling back, dumping into interior space and saves energy by not mixing the warm ceiling air into the occupied zone. Field Installation

PERIMETER HEATING Perimeter heating cannot be accomplished with the same system as the interior load cooling system. Ideally, since ASHRAE 90.1 states that you should not simultaneously cool and heat, the perimeter heating system should be completely independent of the cooling system. Separate ducting of hot or reheated air, hydronic systems, or perimeter fan powered systems are often used to condition the skin load on the building. The TAF-L-W, self contained fin tube perimeter heating plenum utilizes room air to heat the perimeter instead of supply air. The TAF-L-W heating plenum also uses the CT-TAF-L to create a continuous linear look from the occupied space. The TAF-L-W works by allowing the denser cold air, which create convection currents, to flow down a window or exterior wall into the TAF-L-W plenum while also inducing warmer room air into the plenum. A finned tube heater in the plenum reheats this mixed air and room air, returning the heated air to the window or exterior wall through natural convection.

The TAF-L system provides a continuous look around the perimeter. The TAF-L-V cooling plenum used with the CTTAF-L has an engineered throw pattern that never breaks through the stratification layer created by the UFAD diffusers in the core. The dual aperture plate design allows the TAF-L-V / CT-TAF-L assembly to maintain this engineered throw pattern while modulating the airflow volume.

concept of stratification in a UFAD system. Not only does the long throw from the grille mix the air above the stratified layer into the occupied zone, wasting energy, but it also may roll up the glass and across the ceiling, where it drop into the occupied zone causing discomfort for the occupants.

S The TAF-L-E uses the same concept shown above to heat the perimeter with a fin tube electric powered SCR heater. The TAF-L-E is an ETL listed self-contained 4 ft. long sheet metal plenum which attaches to the CT-TAF-L.

APPLICATION GUIDE

The TAF-L perimeter system is modular and allows the designer to use the right number of cooling or heating units required to match the space load requirements. Typically the TAF-L-V, cooling plenums, and TAF-L-(W)(E), heating plenums are alternated as needed throughout the perimeter.

S12

The TAF-L system allows you to remove the fan powered terminals, and their associated energy and maintenance costs, from the UFAD system. However, in the event where the system cannot achieve consistent plenum pressure, a fan powered terminal may be necessary. The PFC was designed to be used as a booster unit for perimeter applications. The PFC fan powered terminal unit is designed to be installed between the pedestals in an underfloor system and installed in a floor 12” to 18” in height. The PFC is usually ducted to linear bar diffusers, such as the CT, or diffuser and plenum units, such as the TAF-D. The airflow of the diffusers is directed at the glass like a typical ceiling system.

When fan powered terminals are used with an under floor system, they are typically equipped with ultra-high efficiency ECM motors. ECM motors consume less energy and can be controlled by the unit DDC controller to adjust the fan speed to the required space load conditions. Modulating the fan speed to vary the amount of air supplied to the zone is the most common control sequence used for the PFC. The PFC controller will determine the speed of the fan based on zone temperature. For example, the fan would run 100% when the zone is 75BF and modulated down to 30% as the zone approaches 70BF.

CONFERENCE ROOMS & OTHER AREAS OF VARYING LOAD Much like the perimeter, conference rooms must be handled separately to adjust for the varying load conditions. The LHK fan powered terminal was designed for this application. Like the PFC, the LHK fits within the modular pedestal systems of the raised floor and is available in various heights to fit under 12” through 18” raised floors. With the exception of its unique dimensions, the LHK is like any other series fan powered terminal. The LHK has a supply inlet with a damper modulated by a controller and actuator. The LHK has an induced air inlet which pulls air from the underfloor plenum or from

APPLICATION GUIDE

UnderFloor Air Distribution www.titus-hvac.com | www.titus-energysolutions.com

the room depending on how the LHK is applied. The LHK supply inlet would be open to the plenum with the induced air inlet ducted to the room as the return. The discharge would then be flex ducted to TAF-R’s in the room. Again to eliminate the fan powered terminal, the TAF-L system can be used to provide comfort conditioning to varying load areas. The CT-TAF-L can be installed in the floor along the wall to provide a clean look. TAFL-V units can be attached to the CT-TAF-L as required to handle the maximum space load. The space thermostat will operate the unit dampers in response to space load conditions. Unused sections of the CTTAF-L should be blanked off beneath the floor. Large space common areas such as break-rooms can be controlled using multiple TAF-R units with electric actuators operated by a common room thermostat.

temperature at the diffuser and you gain the cost benefits of the warmer supply air temperature.

HUMIDITY ISSUES A potential problem with the higher supply temperatures used in underfloor supply systems is the higher potential moisture content of the warmer supply air used in these systems.

The supply system must reduce relative humidity to less than 60% to meet IAQ concerns, and this requires dew points less than 65BF. This implies either reheat or blending of air to achieve a 65BF supply, 55BF dew point condition. System designs utilizing condenser water reheat; runaround coils, face & bypass, and other strategies can be employed to solve these potential design problems. Other possible solutions include the use of a separate system to dry outside air or the use of desiccant dehumidification.

RETURN AIR

If the system must use 55BF supply air for humidity reasons, some of the return air can be re-circulated from the ceiling to the underfloor plenum to raise the temperature of the air to 63BF to 68BF. Another option is to take the return air back to the air handling unit where it can be filtered and dehumidified before re-entering the underfloor plenum. With this option, you can more accurately control the air

Climate and building operation are important considerations when designing a UFAD system. In humid climates, it may be necessary to operate the HVAC system 24 hours a day to maintain acceptable humidity levels in the building.

VENTILATION EFFECTIVENESS ASHRAE Standard 62.1 defines the volume of ventilation air required for a given building space. Table 6-2 shows the adjustment factors to be applied relative to the type of system being employed. For UFAD cooling the factor is 1.0 which is the same as fully mixed overhead cooling and lower than the 1.2 factor applied to Displacement Ventilation applications. ASHRAE research project RP-1373 was funded to compare ventilation effectiveness between UFAD and Displacement Ventilation outlets for several common space applications. The results of the research

APPLICATION GUIDE

Due to the upward air flow, returns should be located at the ceiling or on a high side wall at least 8’ above the floor. This allows the heat from ceiling lights to be returned before it is able to mix with the conditioned air in the occupied zone. There will also be a small amount of “free cooling” due to the natural buoyancy of hot air.

indicated that when the vertical jet from an UFAD outlet reached a terminal velocity of 50 fpm lower than 5 ft. above the floor, the ventilation effectiveness is equal to DV. When the jet projects to a height higher than 5 ft., the ventilation effectiveness is equal to fully mixed cooling. The results of this data will be published in a future Addenda to Standard 62.1. this change may impact the volume of ventilation air required to satisfy LEED requirements when using UFAD.

SIZING JOBS The optimum design point for the TAF-R is 80 100 CFM when a 10BF room / supply differential is used. At this point, the noise is negligible and the pressure required is less than 0.10”. Throw will be less than 5 ft., preserving the desired ceiling stratification layer. Our testing shows that there is 100% mixing in the occupied zone under these conditions. 1.0 W/sq.ft. (computers and printers) +1.2 W/sq.ft. (occupants) =2.2 W/sq.ft. (room load) The stratification in this installation results in a supply - exhaust DT similar to the typical 18BF to 20BF DT common in most conventional systems. For example, with 64BF supply air in a 74BF room, the room exhaust, at the ceiling, will probably be about 82BF, for an 18BF DT. This means that one diffuser can handle:

APPLICATION GUIDE

18BF DT x 100 CFM x 1.08 = 1944 BTUH or 1944 BTUH ÷ 3.41 = 570 watts of internal load. Lights are typically 0.75 W/sq.ft, but with ceiling stratification are probably not a part of the room load (but are seen by the air handler). If computers and printers supply about 1W/sq.ft. load and occupants add about 1.2 W/sq.ft, this translates to: This corresponds to one TAF-R every: 570 Watts of internal heat ÷ 2.2 W/sq.ft. room load = 260 sq.ft. floor space sensed interior zone load.

S14

As a general rule, one TAF-R should be provided for each occupant.

UnderFloor Air Distribution SYSTEM ECONOMICS The main economic considerations for a UFAD system are reduced first costs & installation costs, higher HVAC equipment efficiency, lower horsepower fans, better heat and pollutant removal, quick to install and easy to rearrange office layouts, and lower life-cycle building costs.

FIRST COSTS & INSTALLATION COSTS UFAD systems can be designed with plenum returns using the same floor to floor height as conventional systems by shifting the occupied zone up into where the ceiling plenum would normally be. The cost of the raised floor, typically $5-7 per sq.ft., is offset by the fact that less ductwork is required. The installation costs are usually lower because the HVAC and data / power work is done at floor level. In a conventional system, ductwork must go to every diffuser. UFAD systems use a pressurized plenum to supply each diffuser, so less ductwork is required. In a UFAD system, the only ducting in the underfloor plenum is the ductwork required to supply the diffusers that are more than 50-65 feet away from the dampers or the separation for the perimeter. A 1996 study in Building Design & Construction magazine showed a $2.13/sq.ft. first cost savings using UFAD systems.

HIGHER HVAC EQUIPMENT EFFICIENCY In an UFAD system, supply air enters directly into the occupied zone at the floor level. In a conventional system, the supply air temperature is usually 55BF because it must mix with the warm air at the ceiling before it enters the occupied zone. UFAD systems typically use 63-68BF supply air temperatures. This warmer supply air can reduce energy consumption of the HVAC equipment. Some DX equipment cannot supply air at this high temperature, so this must be considered when selecting the HVAC equipment.

LOWER HORSEPOWER FANS UFAD systems move a larger volume of air with overall lower pressure drops. The diffusers used in UFAD systems operate with less than 0.1” wg, so lower horsepower fan can be used, reducing energy costs.

To maximize flexibility of furniture location during initial installation and re-location during churn, it is recommended that the TAFR diffuser be located at an off center location in the floor tile. This will allow the tile to be installed in the floor stringer with four choices of diffuser location but merely turning the tile. Typical churn in an office is 33%, meaning that everyone moves every three years. Diffusers are rearranged by moving entire floor panel to a new location. This reduces the time and labor costs of relocation and renovation in an office.

LOWER LIFE CYCLE COSTS Several factors of the UFAD system contribute to potential life cycle savings. The building should have an energy savings from the use of lower horsepower fans. The owner should see reduced costs for office layout changes.

Conventional System

By ventilating the underfloor plenum with cool air at night, the structure can be cooled to the point where the load during the early part of the day is significantly lowered. A number of strategies can be employed to take advantage of the potential for stored “cool”, resulting in lowered energy use and off-peak energy use. However, there is a potential for overcooling the occupied space during the night requiring addition morning warm up, costing energy.

There are also costs savings associated with increased thermal comfort for occupants. Because the diffusers are occupant adjustable, the facility staff should see fewer complaints about thermal comfort. Increased employee satisfaction potentially results in increased productivity. Labor costs are typically 10 times the cost of property. A 1% productivity improvement is the equivalent of 22 hours, or almost three days, of gained productivity. For a company with 115 employees earning $35,000 a year, 30 employees earning $60,000 a year, and 5 employees earning $80,000 a year, a 1% improvement would worth be almost $70,000. This is a substantial payback for a building owner.

APPLICATION GUIDE

One way to achieve energy optimization credit is with an underfloor system. An underfloor system may have higher HVAC equipment efficiency as access floor air systems use warmer supply air (63B to 68BF) than conventional systems that use 55BF supply air. Raising the discharge temperature of many system types reduces energy consumption. Underfloor systems can move a larger volume of air with overall lower pressure drops. The underfloor plenum needs less than 0.1” wg of water pressure or less for proper diffuser performance. This results in less fan horsepower needed for underfloor systems resulting in lower energy usage.

UFAD AND LEED

The energy savings of an underfloor system should be considered as part of the system to receive an Optimize Energy Performance credit.

The United States Green Building Council (USGBC) developed the Leadership in Energy & Environmental Design (LEED™) Green Building Rating System™. The LEED council is a voluntary, consensus-based national standard board for developing high-performance, sustainable buildings. USGBC members represent all segments of the building industry and update the program continuously.

ECM motors are another option that should be considered for the Optimize Energy Performance credit. The ECM motor has efficiencies of up to 70% across its entire operating range (300-1200 rpm) and 80% over 400 rpm. The ECM motor is available in the Titus LHK and PFC UFAD fan-powered terminals. See the ECM Application Guide, AG-ECM, for more information.

Credits are based on percentage of reduction and range from 10.5% reduction (1 Point) to 42% reduction (10 Points) for new buildings. The requirement for optimizing energy performance credit is to reduce the design energy cost compared to the energy cost budget for systems regulated by ASHRAE™/IESNA Standard 90.12010. Per LEED, regulated energy systems include HVAC, service hot water and interior lighting. All LEED projects registering after June 26, 2007 are required to achieve at least two (2) Optimize Energy Performance points

If the project is a renovation, Credit 1.1, 1.2, or 1.3, Building Reuse, may be applicable. Credit 1.1 is for maintaining at least 75%, based on surface area, of existing building structure and envelope. Credit 1.2 is for maintaining an additional 20%. Credit 1.3 is for maintaining 50% of existing interior non-structural elements such as interior walls, doors, floor coverings and ceiling systems. Each credit qualifies for one point, meeting the criteria for all three credits nets a maximum of three points for the Material & Resources section. Utilizing access floors systems can update a building for meet current technology needs without demolishing the current building structure. In situations where the architect wants to leave an ornamental ceiling open, access floor air distribution may be the perfect solution.

The credit states that, “Individual adjustments may involve individual thermostat controls, local diffusers at floor,…” as potential strategies to achieve this credit. VAV diffusers, such as the Titus T3SQ would also qualify for this credit as well as access floor diffusers such as the TAF-R.

THERMAL COMFORT Credit 7.0, Thermal Comfort - Design requires that the building comply with ASHRAE Standard 55-2004, for thermal comfort standards. ASHRAE Standard 55-2010, Thermal Environmental Conditions for Human Occupancy specifies the combinations of indoor space environment and personal factors that will produce thermal environmental conditions acceptable to 80% or more of the occupants within a space. The environmental factors addressed in the standard are temperature, thermal radiation, humidity, and air speed; the personal factors are those of activity and clothing.

50% of the building occupants to enable adjustments to suit individual task needs and preferences.

It has been shown that individual comfort is maintained when the following conditions are maintained in a space: • • • • • •

Air temperature maintained between 73-77BF. Relative humidity maintained between < 60%. Maximum air motion in the occupied zone. 50 fpm in cooling . 30 fpm in heating. Ankle to neck level, 5.4BF maximum temperature gradient. Figure 4. Neck Region Comfort Chart

Air Diffusion Performance Index (ADPI) is the best way of assuring that a space will meet the ASHRAE Standard 55 requirement for 5.4BF maximum temperature gradient. ADPI is a single-number means of relating temperatures and velocities in an occupied zone to occupants’ thermal comfort. To calculate the ADPI of a space, you need to measure the temperature and velocities at points throughout the occupied space. The occupied space is defined by ASHRAE as being the area from the floor to the six foot height, one foot from the walls (or in the case of UFAD diffusers, outside of the clear zone of the diffuser). The effective draft temperature is then calculated for each point.

The effective draft temperature (Θ) is equal to the room temperature (tx) minus the local temperature (tc) minus 0.07 times the local velocity (Vx) minus 30. Θ = (tx-tc) – 0.07(Vx-30) The ADPI value is the percentage of the points where Θ is between -3 and +2 F inclusive, with a room velocity of 70 fpm or less. ASHRAE guidelines state that the ADPI of greater than or equal to 80 is considered acceptable. There is currently no method to calculate the ADPI for a UFAD system outside of conducting field measurements per ANSI/ASHRAE Standard 113-2009, Appendix B, Method of Testing for Room Air Diffusion.

APPLICATION GUIDE

The ASHRAE comfort standard states that no minimum air movement is necessary to maintain thermal comfort, provided the temperature is acceptable. To maximize energy conservation, we should attempt to maintain proper temperatures at the lowest possible air speed. The ASHRAE comfort charts, Figures 3 and 4 show the relationship between local air velocity and temperature difference in the ankle and neck regions.

Product samples provided for certification testing are standard production units with standard ½ in dual density fiberglass lining (unless otherwise specified) and no optional appurtenances such as add-on attenuators or heating/cooling coils. The certified ratings are measured at the standard operating points under the following test conditions: • Rated airflow (cfm) – Based on lesser of an inlet velocity of 2000 fpm or the maximum fan flow with 0.25 in wg of downstream pressure. • Rated fan power (watts) – Based on fan operating at the rated airflow with 0.25 in wg of downstream pressure. • Rated Min ∆Ps (in wg) – Min ∆Ps is the difference between atmospheric pressure and the inlet static pressure at rated airflow with the primary damper full open and the unit fan set to match the primary flow. • Rated ∆Ps (in wg) – A static pressure of 1.5 in wg applied to the inlet duct. • Rated sound power by octave band (dB, re 10-12 watts) – Radiated and discharge sound performance conducted in a reverberation room that meets both the broadband and pure tone qualifications of AHRI Standard 220.
