1.1 PRINCIPLE OF OPERATION The operation of a desiccant dehumidification system is driven by two counter current air streams flowing through the desiccant wheel. In the occupied mode, outdoor air (less than 25% of total air flow) and return air are drawn through the filter, the process fan, evaporator coil (where it is cooled and some moisture is removed by condensation on the coil), and the desiccant wheel (where additional moisture is adsorbed). The dehumidified air is provided to the conditioned space. Outdoor air passes through a filter, the condenser coil, the desiccant wheel (where moisture is desorbed), and then through the regeneration fan before being exhausted to the exterior of the building. The emergency return air damper can be used to modulate building pressure by opening to exhaust building air through the regeneration side of the unit to regeneration fan and exhaust. When in the unoccupied mode, the unit closes the outdoor air damper for the air intake. Return air is drawn into the dehumidification section of the unit, dehumidified and returned to the conditioned space. In the High Carbon Monoxide/Dioxide mode the unit dampers switch and the process section takes in 100% fresh, outdoor air and passes it through the evaporator coils and the desiccant wheel and delivers it to the space. The second refrigeration circuit will run when outdoor enthalpy is above 28 BTU per pound of air. The regeneration air inlet dampers will switch to using return air (with the capability of adding some outdoor air if condensing temperatures rise) and will exhaust the return air out of the building. The unit also has hot water heating coils for winter operation. 1.2 DESIGN The galvanized metal frame of the 4000 DES/DX and all of the components used in the design are of solid construction and selected to withstand rugged use in a wide variety of applications. The interior of the 4000 DES/DX is laid out to minimize pressure drop through the system and to reduce the overall unit size. The blowers have a backward inclined design for high pressure, high flow output. The blower motors are provided with variable frequency drives. Maximum fan speed settings can be adjusted to optimize unit for system in which it is installed. The desiccant wheel can be removed from the side of the unit after removing the drive belt and the bolts holding the shaft collar.

The desiccant wheel has a 50/50 split between process and regeneration in order to allow for low temperature operation. The drive system is a belt drive and gear motor. The desiccant wheel has a flexible brush seal system on the periphery and silicon bulb on the face to minimize cross leakage. The regeneration fan has a 7.5 HP, 3 phase, 460 Volt motor and is rated up to 6500 cfm. The process fan has a 7.5 HP, 3 phase 460 Volt motor and is rated for 5000 cfm. The process frequency drive is set to run from 20 to 70 hertz for normal dehumidification but can be adjusted up or down as necessary to obtain the required 5000 cfm at the static pressure required. A control loop in the Automated Logic controller will try to maintain the flow at 5000 cfm by varying fan motor frequency. During dehumidification operation the regeneration blower motor frequency is controlled in the range of 30 Hz to 70 Hz to maintain the regeneration temperature at a set point of 115 °F. The unit is approximately 102.5” wide by 82” high by 222”long. It is mounted on a 10 gage galvanized steel box frame and has lifting lugs on all four corners for both sections. The unit is designed to be lifted as one complete unit and set on a curb. Return air (2), supply air, and outdoor air (2) and regeneration exhaust air are routed through ducts attached to the top and/or sides of the unit as required.
2.0 INSTALLATION The NovelAire 4000 DES/DX Desiccant Dehumidifier is designed to be a standalone unit on the roof or in an equipment room. The 4000 DES/DX outdoor intakes and exhausts are located as shown in figures 1 and 2. Consideration should be taken concerning the location of the outdoor intake for the building to prevent the fresh air intake from being too close to any exhaust ducts that already may be present on the roof or ground. Consult the unit drawings for actual duct location and sizing. IMPORTANT – The 4000 DES/DX is designed to supply air at up to 2.0” H2O. If the system pressure drop in the ducts is higher than this, air flow will be impeded and unit performance will be affected. Regeneration and exhaust fans are sized for 1.5” system static pressure. It is recommended that the 4000 DES/DX be installed so that the control panel and power connections are easily accessible. The unit is designed to allow access to the wheel from the side panels on the process side of the unit. Insure that unit has adequate clearance when choosing an installation site. The unit is designed to be connected to 460 volt 3 phase power with a ground wire. The unit uses 24 VAC control power internally. A separate grounding wire

should also be used. Observe all local electrical codes when connecting unit. Power is connected to the main switch. The unit comes with connection points for the BACNet controller which is capable of communication with Building Automation Systems using the BACNet MS/TP network protocol. Figure 3: BacNet SE6166 Network Connections and 24 VAC Connections Controls are connected to the Automated Logic communication point as follows:

The unit comes with a drain line for the coil. The drain line should be installed with a “P” trap to maintain at least 4” of water in the trap. This will prevent any air leakage through the drain line and allow proper condensate drainage. Drain Line Connections Drain line
Make sure that drain line has proper “P” traps installed to prevent air from being blown out the unit. Trap should have a seal leg of at least 4” H2O. Failure to do so will result in water being retained in the drain pans and leaking inside the unit. Note: The unit is shipped with the R-410A refrigerant. It takes approximately 14 pounds 2 ounces (6.05 kg) of refrigerant to recharge the dual compressor circuit and 12 pounds 6 ounces to charge the single compressor circuit. Use instructions in Appendix A. Refrigerant connections and high/low pressure switch are located in the regeneration air intake section by the compressors.

3.0 OPERATION AND CONTROL The control panel for the 4000 DES/DX is located on the side of the unit adjacent to the supply air outlet and hot water coils. The power is brought into the unit through a conduit connection on side of the control box. A pilot hole has been provided and will be enlarged to accommodate the conduit size used. A separate conduit should be used for control wiring to TB5 control power connections, including the emergency stop (provided by others). Once the 4000 DES/DX is connected to the proper power source, drain line, ducting, and control wiring, it is ready to run. The 4000 DES/DX is controlled by signals from the BACNET network and/or a remote keypad connected to the unit. The unit measures the outdoor temperature and humidity, calculates the inlet enthalpy and determines which operating mode is appropriate. It also receives an occupied/unoccupied signal that determines the source of the air stream to be dehumidified. Main Power Variable Frequency Drives Pressure Trasmitters Circuit Breakers Transformers Control Terminal Block Automate Logic Controlers Fuses

The operating sequence is detailed in the attached appendix. In summary, the unit will operate in one of the following modes: 1. Dehumidification mode, occupied 2. Dehumidification mode, unoccupied 3. High CO/CO2 Ventilation (occupied or unoccupied) If outdoor enthalpy is above 28 BTU/pound, the second refrigeration circuit will operate. 4. Unit has hot water coils for heating when necessary.
3.1 CONTROL The 4000 DES/DX is controlled by an Automated Logic control system consisting of two SE6166 modules. The control logic printout is included in the appendix. The 4000 DES/DX has a high and low pressure switches which will stop the unit from running if the either the pressure is low for more than three minutes or the high pressure trip point of 500 psig is reached. The switch will have to be manually reset before the unit will restart. Setting high pressure trip higher than 500 PSIG may result in compressor damage. The unit uses 24 VAC control power for all the run relays for the frequency drives and the compressor contactor. This power will be disabled anytime a door is opened in compartments containing rotating equipment for safety reasons as well as for high or low refrigerant or high water in drain pans. 3.2 OPERATION 3.2.1 First Time Start Up of the 4000 DES/DX 1. Be sure that there are no obstructions to the free flow of air into or out of the unit. 2. Insure that drain line is connected to the unit. 3. Insure that main unit is charged with R-410A refrigerant according to Appendix A. Unit is shipped with charge unless otherwise noted. 4. Insure that unit has been properly wired to 460 volt, three phase power. If the phase is wired incorrectly, the rotation relay will keep the compressor from running in the wrong direction and keep the desiccant wheel from coming on. If power is corrected correctly, the green light on the relay will come on when the compressor circuit breaker is on. To correct, simply switch two wires at the disconnect switch to change direction of rotation. The
13
5. 6. 7. 8.
variable frequency drives will rotate fans in correct direction no matter which order the main power lead are connected. Insure that the BACNET is connected correctly and addresses are correct. Turn on all circuit breakers for the unit. Control lights should be lit on the SE6166 controllers. Connect the SE 6166 to the control network. (See specific instructions provided with SE 6166) for settings and connection points. The unit is now ready for routine operation and can be started using the BACNET system.
3.2.2 Normal Sequence of Operation of the 4000 DES/DX GENERAL: The unit is a 100% return air unit designed to precondition and dehumidify the return air being introduced into the air stream to a conditioned space. The unit is capable of mixing up to 25% outdoor air with the return, which is controlled by a damper. The unit is intended to operate year around to provide humidity control on the mixed air. The unit is controlled by an Automated Logic controller system. Refer to attached sequence of operation in Appendix for further information on the normal sequence of operation.

4000 DES/DX Unit Description The unit consists of a main refrigeration loop with tandem compressors, condenser, TXV valves and evaporator coils and a desiccant wheel which is regenerated with the condenser heat from refrigeration circuit. There is second refrigeration loop that runs when the unit is in High CO/CO2 mode and taking in 100% outside air. The condensing temperature and compressor amps are monitored and airflow through the condenser is controlled by a variable frequency drive directly coupled to the condenser fan impeller. The condensing air leaving temperature is controlled in the range of 110 ยบF to 125 ยบF by the temperature controller as required for regeneration of the desiccant wheel. During startup, the compressor amps should be monitored and not allowed to exceed preset maximum amps. Should amperage exceed maximum amps, the regeneration fan should be increased to maximum flow until condenser leaving air temperature is below set point and compressor amps are below maximum amps. In occupied mode, 25 % fresh outdoor air mixed with 75% return air passes through filters, the process fan, and the evaporator coil. It then passes through the desiccant wheel and the hot water coil before being discharged to the conditioned space. If discharge temperature goes below 55 ยบF, the hot water heater can be used to raise the discharge temperature. When a high CO/CO2 condition occurs, the unit will be commanded by the BAS to run in high CO/CO2 mode. Dampers will change to pass 100% outdoor air through the process side of the unit and discharge return air through the regeneration side of the unit. If outdoor enthalpy is above 28 BTU/pound dry air (actual level may vary by installation), the second refrigeration circuit will operate to reduce the supply air enthalpy and moisture content entering the building. Moisture is removed by the evaporator coil when its refrigeration circuit is in operation and then by the desiccant wheel. The following is the sequence in which the refrigeration circuits will run during calls for operation during either occupied or unoccupied modes. The unoccupied mode is an optional mode that can provide either dehumidification or heating. Enable, Occupied Command 1. Unit will energize and 2. Return air damper open 100% and outside air damper open to provide 25% outdoor air. 3.

SEQUENCE OF OPERATION –4000 DES/DX Version 4 3/9/2011 GENERAL: The unit is a return air unit designed to condition and dehumidify the return air being introduced into a warehouse or storage building. The unit is intended to operate year around to provide humidity control of the return air. The unit has the capability to also process up to 20% outdoor air to provide additional ventilation. The unit is configured with an emergency ventilation mode that will provide 100% outdoor air and use the return air for condenser fan operation when a high carbon monoxide (CO) level occurs in the storage space. The unit can also operate in an unoccupied dehumidification mode which will not introduce outdoor air for ventilation. The unit will be controlled by an Automated Logic controller system connected to BACNet network.

4000 DES/DX Unit Description The unit consists of two refrigeration loops with compressors, condensers, TXV valves and evaporator coils and a desiccant wheel which is regenerated with the condenser heat from the larger refrigeration circuit. The condensing temperature and compressor amps are monitored and airflow through the condenser is controlled by a variable frequency drive directly coupled to the condenser fan impeller. The condensing air leaving temperature is controlled in the range of 115 ºF to 125 ºF by the temperature controller as required for regeneration of the desiccant wheel. During startup, the compressor amps are monitored and not allowed to exceed a maximum amp level to protect the compressor. Should amperage exceed the maximum amps, the regeneration fan will increase to maximum flow until condenser leaving air temperature is below setpoint and compressor amps are below the setpoint amp level. In occupied mode, up to 20 % fresh outdoor air is mixed with return air after passing through filters. The damper position of the outdoor air will control the amount of outdoor air provided and will have to be setup during startup balancing. The mixed air then passes through the process fan and the emergency and main evaporator coils. It then passes through the desiccant wheel and the hot water coil before being discharged to the conditioned space. Outdoor air is supplied to the regeneration side of the unit to remove heat from the condenser. A control loop is provided that will allow the return air damper to control building static pressure. The static pressure signal is provided through BMS system, as it is impossible to control building static by sensors inside the unit due to filter, wheel and coil pressure drop effects. If building static is measurement is not available, then an additional pressure sensor will have to mounted remotely for each unit. The unoccupied mode is the same as the occupied mode except that the outdoor air damper is closed and the return air damper connected to the regeneration stream is closed. The Emergency Carbon Monoxide mode closes the return air damper on the process side and opens the outdoor air damper 100%. The outdoor air damper on the regeneration side of the unit closes and the emergency return air damper opens 100% to provide ventilation of the space. The emergency cooling circuit will energize to provide additional cooling. If evaporator coil leaving temperature going to the desiccant wheel drops below 40 °F, the emergency refrigeration circuit will cut off to prevent coil freeze up and will not come back on until Emergency Carbon Monoxide mode is reset. If necessary, the regeneration outdoor air damper may modulate open to control compressor amps for the emergency circuit. The following page contains a summary of the sequence for each mode of operation.
Enable, Occupied Command 1. Unit will energize and 2. Process Return Air Damper opens and Process Outdoor Air Damper opens to preset position (set during startup balancing). 3. Regeneration Outdoor Air Damper and Exhaust Damper open. Regeneration Return Air Damper may modulate to provide relief air from space. Maintain close to neutral space pressure by utilizing pressure controller. (Pressure input from BAS?) 4. Unit will energize process fan. 5. Unit will energize regeneration exhaust fan. 6. Desiccant wheel will start up. 7. Compressor(s) will start up. 8. Temperature controller will start controlling condenser air leaving temperature by controlling regeneration fan speed. 9. Post heating will function as necessary to control leaving air temperature. 10. When required, regeneration return air damper will modulate to control building pressure based on signal for building static pressure sensor signal (provided by others) from BMS. If building static is measurement is not available, then an additional pressure sensor will have to mounted remotely for each dehumidification unit. Enable, Unoccupied Command 1. Unit will energize and 2. Process Return Air Damper opens and Process Outdoor Air Damper closes. 3. Regeneration Outdoor Air Damper and Exhaust Damper open. Regeneration Return Air Damper goes to 100% closed position 4. Unit will energize process fan. 5. Unit will energize regeneration exhaust fan. 6. Desiccant wheel will start up. 7.
