Whereâ&#x20AC;&#x2122;s the Meat? Temperature Optimization Achieves a Quick Payback A gourmet meat producer was constantly sanitizing his food preparation equipment due to inconsistent temperature in his prep space. Production stopped every four hours which caused expensive downtime. His contractor dropped the Head Pressure from 110F to 70F SCT, removed the refrigerant from the receiver and added an Emerson Electronic EX Valve to every evaporator. The results were astounding. Production downtime was eliminated which yielded an additional 25% in capacity with only 5% increase in energy. The overall optimization program provided the end user with a utility incentive of $9875 from his local utility provider. Find out more at optimize.climate@emerson.com or call 519.756.6157.

EX valves Enhancing energy efficiencies 42 REFRIGERATION

One often ignored method to achieve performance and energy efficiencies is through lowering the condensing (or head) pressure in refrigeration systems. EX valves allow operators to do this. Andrew Patenaude

76 cover story

Although his No. 27 is synonymous with the Toronto Maple Leafs, Sittler is just as well known for the number 10. This NHL Hall of Famer has the distinction of holding one of the most prestigious NHL records to this day. Andrew Snook

How to

oversizing (Sometimes)

A battery of choices 102 COMMERCIAL PLUMBING

There are several choices when it comes to power sources for electronic plumbing fittings. All have advantages and disadvantages, depending on the application. Jason Boyd

70 HYDRONICS

Oversizing components increases costs, so it is best to size things correctly, per the design, however there are times when some parts can be a little larger than the system calls for. Eric Riml

M B s P E C I AL I STS 192 MARKETING Another round of great marketing questions Doug MacMillan Last issue I started a list of some of the most common or most intriguing questions that I’ve been asked about marketing over the past little while. It was a fun exercise, so let’s continue the dialogue.

196 ASK ROGER Seeking a smooth transition Roger Grochmal Most people spend more time planning a vacation than they do the important elements in their lives and companies, including their exit strategy.

200 REFRIGERATION Variable frequency drives in compressors Phil Boudreau The mechanical world is seeking ever-higher efficiencies, and the refrigeration sector is not immune to this. One of the more recent options to hit the market are compressors equipped with variable frequency drives.

206 hydronics Let my BTUs flow! Bob “Hot Rod” Rohr If I were to choose one concept (and related products) that has changed the way we pipe boilers, the hydraulic separator would be the standout choice.

208 HIGH PERFORMANCE HVAC Sealing the deal Gord Cooke Forced air HVAC systems simply cannot be efficient with leaky duct systems, but there are options available that can ensure that nary a single cfm of air is wasted en route to its job to provide occupant comfort.

212 PLUMBING To wet vent or circuit vent Fred Bretzke Let’s look at the rules in place for wet venting and circuit venting, as well as the pros and cons of both options.

Sweaters just address a symptom, not the problem As I was driving into the office to put this edition together, I caught a news mention of National Sweater Day, an effort promoted by the World Wildlife Fund every February asking Canadians to put on a sweater and turn their thermostats down by two degrees in an effort to conserve energy. While the goal of energy conservation is to be lauded, as someone who is involved in the industries that provide thermal comfort to these sweater-bound Canucks, I cannot help but feel that the effort is overlooking the obvious. If we want to be comfortable and save energy, then why don’t we just make the mechanical systems work better, and more efficiently? A trip to a trade show, like the recent AHR Expo in New York or the upcoming CMPX Show in Toronto, is a perfect opportunity to look into some of the options available to us to provide both comfort and efficiency.

Visit us at CMPX 2014 The CMPX Show hits the Metro Toronto Convention Centre from March 19 to 21, and we’d like to see you there. Visit our booth, N22, just to the right at the top of the escalator, and be sure to get a head start on the show with our Show Guide, starting on page 124.

For example, a zoned system, whether in a home or office, is an ideal way to minimize cmpxshow.com energy use. As is upgrading an older furnace with a new 95-plus AFUE unit, or building a system around a geothermal heat pump, or targeting high SEER ratings with the air conditioners that are recommended to customers.

A secondary benefit of recommending higher SEER cooling equipment is that it also helps avoid the media pushing Canadians to hang out in boxers and T-shirts in the dog days of summer – think twice before visualizing this. We have tools available to us. Even something as simple as sealing ducts with foil tape and ensuring that filters are sized appropriately and changed regularly can impact our use and conservation of energy. We just need to make consumers more aware of what can be done. If you are not able to get to a show, either the upcoming one in Toronto or any of the regional events that are coming later this year, I encourage you to check out our Products in Profile pages, starting on page 137 of this edition. PIP is our biennial “trade show in print”. It is a fantastic showcase of the latest in technology that’s available here in Canada.

Hug a plumber World Plumbing Day took place on March 11, 2014. The international event, initiated by the World Plumbing Council, celebrates the vital role of plumbing in the health and safety of societies around the world. So, to all our plumbing-related readers around the country, here’s a big thank you from all of us at Mechanical Business!

Nik Ljiljanic, commercial sales leader for Trane Toronto recently welcomed corporate and commercial guests to Trane’s EarthWise seminar and 100th anniversary celebration at The Thompson Hotel in Toronto. In addition to being an opportunity to mark the company’s centenary, the event was a platform for Trane systems experts to discuss new technologies and opportunities to target energy efficiency with HVAC solutions. Among the discussions were such topics as energy trends, thermal storage systems, emerging refrigerants, and system and operational costs.

AHR Expo attracts a crowd in NYC A fierce winter storm made getting to New York City a bit of a challenge, but even Mother Nature couldn’t hold the 2014 edition of the AHR Expo down. Even with flight schedules to juggle, the aisles were packed all three days with more than 50,000 industry personnel from all over the world. A showcase for the latest products and technologies for the HVAC/R market in North America, this year’s event featured numerous digital technology offerings, and saw considerable focus on controls and equipment designed to enable remote monitoring of systems. The 2015 AHR Expo will take place from Jan. 26 to 28 in Chicago.

EUB increases margin The New Brunswick Energy and Utilities Board awarded an increase of 5.2 cents per litre to the margin of home heating oil on Feb. 6. William Gould, president of COHA New Brunswick, commented that he sees the decision as a positive step in the right direction, but added that much more work is needed to be done to continue to keep the oil heat industry viable.

The Province of Ontario recently made it law for carbon monoxide monitors to be installed in Ontario residences with a fuel-burning appliance, heating system, fireplace or attached garage. climatecare.ca

The City of Vancouver was recently awarded a World Green Building Council (WGBC) Government Leadership Award for Best Green Building Policy. The city was recognized for its Greenest City 2020 Action Plan, which was held up as an example of excellence in sustainable city policies. The action plan’s two major targets are to require all new buildings built from 2020 onward to be carbon neutral, and to reduce energy use and greenhouse gas emissions in existing buildings by 20 per cent over 2007 levels by 2020. The announcement was made during the UN Climate Change Convention in Warsaw, Poland. worldgbc.org

BCUC reaches decision on regulatory framework The British Columbia Utilities Commission (BCUC) has released its decision on the creation of Order G-231-13, a new regulatory framework for Thermal Environmental Systems (TES). One of the key points within the framework is to make any system less than $15 million in size, but larger than a value yet to be determined, exempt from economic regulation and specific sections of the Utilities Commission Act. The Coalition for Open Competition is urging the Government of B.C. to approve the exemptions on the grounds that it would reduce red tape and unnecessary regulations that hinder economic development. For more information, contact HRAI’s Martin Luymes at 1-800-267-2231 ext. 235, or email mluymes@hrai.ca.

Balloon-type ball backwater valve chosen for pilot project The Standards Council of Canada (SCC) recently announced the selection of the balloon-type ball backwater valve as the focus of a joint Canada-U.S. pilot project that focuses on standards development for new or emerging product areas where neither standards nor regulations currently exist. The valves are used in drainage pipes where reversal of flow causes the valve to close-off and prevent sewage from potentially causing flood damage. scc.ca

Profile Tim Meadows: Having fun while giving back

It’s not unusual to see Victaulic’s Tim Meadows and his wife Theresa cutting a rug at industry events throughout the year, but for Tim, his involvement at the association level is not just about getting out and being social. He sees it as a way to give back to the industry and encourage others to do the same. His efforts were formally recognized this past fall when the Mechanical Contractors Association of Canada presented Tim with the Doug Crawford Memorial Award, which recognizes an associate member who has made a substantial contribution to MCAC through regular

voluntary participation and leadership, with a history of commitment to ensuring the success of its members. Daryl Sharkey, MCAC’s director of member services, explains that Tim, who is now the past-chairman of the Associates Council, “has put the needs of the association first and has been an excellent example for all future board members.” Nice job Tim, and we look forward to catching you on the dance floor again soon.

Q A Q A

How did you get started in the industry?

Tell us about Victaulic.

I like to describe Victaulic as a dynamic organization focused on growth and innovative piping solutions. We were founded in 1925 and are the world leader in grooved and plain-end mechanical pipe joining systems.

Getting smart with

therm N

stats

ew technology in thermostats has made dramatic leaps forward over the past 10 years. We’ve gone from “It has a setpoint” to “It has programmable setpoints for various times of the day, and even a vacation mode” to “Let me adjust my home thermostat from my office while I’m booking my family’s next vacation on my iPhone.” Like smartphones, the technology-enhanced thermostats are called smart thermostats. And like smartphones, the original function of a thermostat has been overshadowed by “wow” features. No one gets excited anymore about the fact that they can simply talk on their phone. Similarly there is rarely a mention about how well smart thermostats control temperature. It’s all about appearance, remote access and added features. It wasn’t that long ago that a thermostat was something no one wanted to see. Interior decorators hated them. They were even called “wall acne.” The thermostat brand Nest has helped to change all that by making temperature control undeniably “cool” for consumers with Wi-Fi connectivity and an aesthetic that people buy for its looks alone. We in the industry may scoff at such an approach, but it has been immensely successful. Navigant Research Company’s senior research analyst Neil Strother explains that of 11 thermostat brands his company rated in terms of strategy and execution in the smart thermostat market, Honeywell led in brand recognition, but Nest and ecobee – both relatively new players in the market space – landed in the top five, which is a testament to the readiness of consumers to embrace technological bells and whistles with their HVAC controls.

HONEYWELL

Indeed, while some may think that Nest stepped on Honeywell’s turf, perhaps it’s the other way around. Not long after the Nest thermostat was unveiled, Honeywell introduced its Prestige thermostat. While still a traditional rectangular shape, it can be customized into a myriad of bright colour combinations and promises a more user-friendly intuitive method of programming that most homeowners should be able to manage. Of course it is Wi-Fi-capable, as are Honeywell’s more basic programmable thermostats.

M e c h a n i c a l

B u s i n e s s

Nest has turned the world of thermostats upside-down with the appearance of the “Nest Learning Thermostat” in 2011. It was developed by a couple of former Apple executives who wanted iPhone or iPad Wi-Fi connectivity for their temperature control. They wanted to vary setpoints (what we in the HVAC biz call programming) without the tedium of standing at a wall punching buttons. In fact they didn’t want to program it at all, but rather to have it “learn” by itself. The thermostat senses the comings and goings around it, and programs itself over the next few days. And finally, it had to be aestheticallypleasing. All this adds up to what consumers call “cool.”

We might think that more traditional thermostat manufacturers would be upset with the new players in the market, but that may be an oversimplification of the story. While not embracing their new competitors with open arms, a Honeywell rep that I spoke with acknowledged that companies like Nest have had some positive effect on the market. “They pioneered where the industry needed to go.”

Before Nest, the modern thermostat was generally a white box of rectangular plastic. Even Honeywell had expanded beyond its sacred “round.” Low and behold, Nest came out with a round thermostat with a stainless steel rim and an intenselycoloured middle that changes; red is for heating, blue for cooling, and continues on page 30

black for no call for either. A bright green leaf appears to announce an energy-saving mode. Nest is truly different, says industry veteran distributor Jaylan Phillips. “I get lots of stats to try out at home because I’m in the business. But this is the first that my friends have even noticed. More than that, they say it’s cool.” Perhaps even more mould-breaking is the way Nest goes to market. Traditionally a thermostat was just an HVAC accessory, to be sold along with the installation of new equipment, or to replace a failed thermostat, or as an energy-saving upgrade – all of which was handled by the HVAC contractor. In contrast Nest went full-bore after consumers who love new technology. Consumers learned about it in popular publications such as Wired, GQ, the NY Times, and National Geographic. Where does a consumer get one? Online, of course, or from an electronics retail store such as Best Buy. And Nest encourages the end user to handle the installation, or to use one of their installation contractors – a list that is not exclusive to HVAC contractors, but rather also includes audio-visual and energy management firms as well. This might be a development that mechanical firms might want to plan a strategy around.

ecobee The ecobee (Yes, lower case is correct) thermostat targets a market even more technically-oriented than Nest’s. According to CEO Stuart Lombard, its target audience is internet and smartphone users who want to save energy. The ecobee thermostat gathers data about energy usage, including how fast a home or building warms up. Reports to the user include comparisons of energy usage in similar buildings and locations, how to increase energy efficiency, and even a weather forecast. Data is available online, and on the thermostat screen itself. Even though the target audience is extremely technologically savvy, ecobee’s is proud of being completely loyal to the traditional HVAC industry. It sells only through HVAC contractors. continues on page 32

A drier footprint Water conservation will continue being a driving force in the market, reports American Standard’s Simone Abele. “Overall awareness for water consumption will increase as water costs increase and shortages increase,” she says. “The challenge is to come up with products with no impact on performance but reduce water consumption.” Moen’s Gary Scott agrees, saying that consumers are looking for products that save water and last a long time. “It’s a popular trend,” he says. “Being greener, leaving less of an impact on the planet, and saving energy is top of mind.”

Generation ageless American Standard’s Simone Abele says although Canada’s aging population doesn’t have a direct influence on contemporary design trends, they do influence aspects like making products easier to use.

Donna Church, marketing and communications manager for Kolher Canada, says companies need to innovate in categories such as comfort height toilets and walk-in baths in order to meet the needs of this particular demographic. “Boomers are demanding products that help them age in place and this is especially important in the bathroom where slips and falls can happen,” says Church. Garry Scott, Moen Canada’s vice-president of wholesale marketing and branding, agrees that boomers are looking to safety as being a concern in the bathroom. He says this is increasing demand for the installation of such items as grab bars and slide bars; however, the aging population is also looking for them to be stylish and not have an institutional look to them.

Boomers, conservation and the digital age

athryn Holman, showroom supervisor for Desco’s Water Closet in Kitchener, Ont., says out of every 10 houses she works on, approximately two of them have traditional designs; the rest are modern contemporary. From aging in place to changing technologies to an increased demand to reduce water consumption, there are numerous factors influencing contemporary design choices in today’s bathrooms.

“Companies are making a lot of high-end products for barrier-free, so it doesn’t look like a bathroom out of a hospital,” says The Water Closet’s Kathryn Holman. “You can still do it pretty elegant, even if its wheelchair accessible.” Redesigns and renovations for improving continues on page 38

Sinks and Faucets Modern looking faucets and fixtures are dominating today’s bathrooms. American Standard’s Simone Abele, vice-president of marketing for American Standard Brands, says monoblock designs for faucets are increasing in popularity. “It’s all about the cleaner look that’s less traditional,” she explains.

Delta

“Everything has become higher – toilets, pedestals. Everything used to be 31 to 32 inches, now it’s 34- or 36-inch heights because it’s more comfortable,” he says.

Chrome continues to be the most popular finish for faucets in the bathroom, with a little selected gold within the higher end of market,” says Abele. “Ninety per cent of all fixtures we sell are chrome,” adds Kitchen & Bath Classics Christine Gurr. Masco’s Krystin Lee adds that polished nickel is also a popular choice in the Canadian marketplace.

Tubs and showers According to The Water Closet’s Kathryn Holman, free standing bathtubs have shown a significant increase in popularity in the past 12 months.

Another trend taking place in contemporary bathrooms is increased demand for a more luxurious shower experience, says Moen’s Garry Scott. He said contractors can offer vertical spas and body sprays as a relatively inexpensive upgrade to consumers.

Hansgrohe

“We’re probably selling twice or three times as many as last year,” she says.

Generation Ageless CONT’D living conditions are more important to baby boomers right now than renovating for the purpose of selling their homes, explains Scott. “Generation ageless is redefining what it’s like to be old,” he says. “People want to live in their current home as long as possible, and are willing to remodel and redesign their home if they are planning on living there for a longer period of time.” “We’re seeing a lot more major bathroom renos as they fix their homes,” adds Masco’s Krystin Lee. Carolyn Cheetham, executive vice-president and architectural technologist for the National Kitchen and Bath Association (NKBA), says there are a variety of other add-ons available in the marketplace that can help older Canadians have comfortable experiences within the bathroom, including heated floors and magnified shaving mirrors.

Wall-hung and high When it comes to toilets, increased heights and wall-hung units are on the rise. Christine Gurr, showroom manager for Kitchen & Bath Classics in Lethbridge, Alta., says wall-hung toilets offer a clean, modern look. “I rarely even sell a regular height toilet anymore,” adds The Water Closet’s Kathryn Holman.

A digital future A trend that is continuing in the Canadian market is the demand for the integration of technology in the bathroom. Christine Gurr, showroom manager for Kitchen & Bath Classics in Lethbridge, Alta., says this is particularly true in large urban centres.

M e c h a n i c a l

“Design isn’t the only thing that makes a bathroom contemporary, Canadians are looking for dual-purpose products in all aspects of life and that applies to products in the bathroom as well,” says Kohler Canada’s Donna Church. “Consumers want and look for the most innovative products to

achieve those goals.” “Hands-free everything,” adds American Standard’s Simone Abele. “Integrated toilets, hands-free faucets, multi-function products like music in the shower. We see technology becoming a huge part of the bathroom.”

High-performance HVAC Refrigeration

BB y yGo A nr dd rCeoPoat ke enaude

Enhancing Energy Efficiencies maximum RPMs, even when idling or driving slow — common sense tells us this is unnecessary.

Unfortunately, many operators are simply unaware that low condensing operation is a viable, energyefficient and cost-effective alternative to the fixed head pressure method.

Electronic expansion valves enable low condensing refrigeration

n the past decade, modern refrigeration and air conditioning systems have progressed to offer the very latest mechanical and electronic component technologies. System operators and technicians now have a variety of performance-enhancing and energy-efficiency options to precisely match system capacity with demand, and to better tailor operating parameters to the ambient temperatures. One often ignored method to achieve performance and energy efficiencies is through lowering the condensing (or head) pressure in refrigeration systems. The majority of refrigeration system operators elect to run systems with fixed head pressures, which forces compressors to run at maximum output regardless of the ambient temperature or demand. For decades, operators have been taught that maintaining fixed head pressures above 105°F was standard operating procedure. It’s akin to forcing a car engine to run at

Benefits of

low condensing With the ample opportunities to take advantage of lower condensing conditions, operators may find it increasingly difficult to justify the business case for maintaining high head pressures year-round. When it’s 35°F in December, it stands to reason that you wouldn’t want to operate your system as if it was 85°F in July. Operating at fixed head pressures places consistent mechanical stress on the system, and the many potential energy and performance benefits are left unrealized. These include: • Lower energy consumption/costs; • Increased compressor capacity at lower condensing pressures;

• Maintenance cost reductions; • Preventing compressor failure from flooding; and • Utility incentives to upgrade systems.

M e c h a n i c a l

B u s i n e s s

Ben Kungl, owner of Oxford Energy Solutions in Ontario, has been working exclusively with EX valve systems for more than eight years. “In the past we needed to maintain high head pressures to make the mechanical valves work properly. With the technology and the accuracy of today’s electronic valves, we now have expansion devices that allow us to float the head pressure and take advantage of the lower ambient temperatures,” Kungl said.

Reintroducing low Due to today’s emphasis on energy-efficiency initiatives, the refrigeration industry is re-thinking its stance on low condensing operation. Manufacturers have developed electronic expansion valves that are capable of operating within a wide range of condensing pressures. Unlike the TX valves used in fixed head pressure applications, EX valves are capable of digesting the flash gas that’s produced in low condensing systems as the head pressure floats with falling ambient temperatures. EX valves can even be retrofitted into existing systems with fixed, variable speed or digital compressors. EX valves provide a capacity modulation range from 10 to 100 per cent, modulating in a linear, stepped fashion. As the ambient temperature starts to drop, the head pressure floats down and the compressor capacity increases, EX valves can easily handle the transition in capacity ranges. If the liquid refrigerant quality changes and causes flash gas to form, the EX valve will modulate, digest the flash gas and control superheat.

• Improved sustainability by reducing refrigerant system charge;

Today, technological advances in electronic expansion (EX) valves are enabling existing systems to operate with floating head pressures. EX valves allow operators to lower the condensing points to drastically reduced minimum levels that are more closely aligned with the fluctuations in ambient temperatures throughout the day and across the seasons.

0 4 . 1 4

Operators will find that the opportunity for energy savings increases as the ambient temperatures drop and head pressures fall. Depending on the compressor type and make, a typical system can achieve 15 to 20 per cent energy efficiency ratio (EER) improvements on the compressor for every 10°F decrease in head pressures.

What are low condensing and floating head pressures?

Low condensing refrigeration refers to the practice of lowering the condensing temperature to a minimum set point well below typical fixed condensing pressures. The condensing temperature is commonly referred to as either the head pressure or the condensing pressure in a refrigeration or AC system. Traditional refrigeration systems maintain a fixed head pressure above 105°F degrees, typically relying on mechanical head pressure control valves or fan cycling to maintain fixed pressure. The term floating head pressure is synonymous with low condensing and describes the practice of varying (or floating) the condensing pressure in unison with fluctuations in ambient temperatures. The head pressure typically remains at 10 to 20°F above the ambient temperature, and is controlled by pressure regulators or through cycling (or varying) the speed of condenser fan motors. This method requires the designation of a minimum saturated condensing temperature (SCT) to establish the lowest point at which the system is able to operate effectively. As the ambient temperature rises in a floating head system, the condensing pressure will float up with it. But, when the ambient temperatures fall the head pressures will also track with the decrease in temperatures — and that’s where energy savings can be realized. continues on page 44

Percentage of Time Temperatures Fall Below 60°F

As the condensing temperature drops, the compressor wattage decreases and capacity (BTUH) increases. Because of the increased capacity, compressor runtime hours are significantly reduced, and compressor lifecycle reliability is much improved.

By lowering the minimum SCT, operators have significant opportunities for savings in North America. In Canada, the ambient temperature is 60°F or below for 90 per cent of the year. In the central U.S., the temperature is below 60°F for 60 per cent of the calendar year. Even in the southern tip of Florida, the ambient temperature is below 60°F for 20 per cent of the year.

When temperatures are below 60°F, refrigeration systems can capitalize on low condensing operation. There are potential significant savings opportunities in North America.

Comparing fixed head pressure operation (dotted red line) with floating head pressures (dotted blue line), the area shaded green shows the potential energy saving opportunity in a 24 hour period.

“Now that you don’t need to maintain a high head pressure, you can float the head down to take advantage of the low ambient conditions in the fall, winter and spring — and even summer nights,” he says. “You’ll achieve a smaller compression ratio, greater capacity and less kilowatt input per BTU output. The reality is, this is the way refrigeration should be done.”

Case

Immediate benefits in cold Study storage warehouse

‘

Problem For years, a Canadian food processor had been operating a 100-ton, -20°F freezer, running year-round on R-404A at a fixed 110°F SCT. When warm product was introduced into the cold storage warehouse, operators experienced a slow pull down of temperatures. And, they had grown accustomed to losing one compressor per year, on average.

’

Solution Ben Kungl of Oxford Energy Solutions recommended a system that allowed his customer to lower the condensing point and float the head pressures. By adding EX valves to each evaporator and a variable frequency drive to condenser fan motors, he was able to drop the minimum condensing temperatures from 110°F to 70°F. Immediately, the warehouse achieved faster pull-down rates. After one year of use, his customer achieved a 50 per cent reduction in energy costs. In the six years since the retrofit, the contractor has not had to replace a single compressor. On one occasion, every evaporator fan motor in the facility stopped due to an outage on the 208-volt power source. Since the compressor and EX valves were on a different voltage, they were unaffected by the power loss and kept running. Instead of flooding back to the compressors due to no air flow and no

evaporator heat load, the EX valves throttled closed to control their superheat set point. As the valves continued to close, the suction pressure gradually dropped until the condensing units shut off on their lowpressure safety modes. Kungl said this feature alone is a huge cost saver. “It’s inevitable that operators or employees accidentally shut the power off, leave the doors open to the freezer, or an evaporator fan motor is lost,” he said. Normally, this would result in serious problems, such as a frozen evaporator or compressor loss. “That doesn’t happen with EX valves, because they’re able to monitor superheat very accurately. As soon as it begins to flood back, the valve simply closes because it knows there’s no heat in the evaporator. It will save the compressor by shutting it off on safety mode,” said Kungl. By lowering the condensing temperatures and allowing the system to float its head pressures, the contractor also significantly reduced the amount of refrigerant used in the system — a fraction of refrigerant is needed in the condenser during low temperature operation.

Overcoming early limitations

Reducing refrigeration energy costs The state of California recently implemented a low condensing requirement in its Title 24 energy-reduction regulation, requiring floating head pressure systems to have a minimum set point of at least 70°F. If this is any indication of what the future will be for the larger North American region, the practice of low condensing refrigeration may soon be gaining wider adoption. Lowering the minimum set point is the most obvious opportunity for legacy equipment to save energy, improve sustainability and reduce maintenance costs. Floating the head pressure allows the compressors to operate in a relaxed state when temperatures are low, while providing more capacity and consuming significantly less energy. Finally, the type of compressor used in the system does not matter, because EX valves are designed to control superheat of the evaporator based on a minimum set point. “And at the end of the day, it’s a cheaper installation and much more efficient system. We’ve never had a system failure with an electronic expansion valve in eight years,” says Ben Kungl.

Traditionally, refrigeration and AC system operators have artificially kept head pressures high all year long to accommodate the limitations of mechanical thermal expansion (TX) valves. The TX valve, which controls the refrigerant flow into the evaporator, is the main driver for maintaining these artificially high pressures and liquid quality all year. Decades ago, when balanced ported mechanical TX valves were used in the first attempts at lowering the condensing pressure, they were unable to maintain capacity and digest flash gas (bubbles) that formed in the liquid as the pressure floated lower. The flash gas ultimately choked the TX valve, and like drinking through a straw with a hole in it, the TX valve couldn’t produce the necessary volume. As a result, system aids such as mechanical heat exchangers, liquid pressure amplification pumps and sub-cooling loops were introduced into these low condensing systems to control flash gas. However, the industry soon decided these measures were excessive and opted to bring the head pressures back up to a fixed point. To this day, the majority of system operators in North America keep their head pressures near 105°F, which is considered acceptable because it works within the limitations of mechanical TX valves. What many operators do not realize, however, is that technology now exists that will enable them to float their system pressures down to a 70°F (or lower) condensing temperature, thereby achieving significant energy savings.

A i>Right, up front

The Regina Provincial Correctional Centre is a medium- and highsecurity facility in Regina, Saskatchewan. The 10,603 m² building has 112 staff and houses up to 427 inmates.

Radiant Wall Casting Call

Cast-in-place concrete is used for a wide variety of applications due to its long-term durability. Standard uses include structural support in the form of beams and columns, and in floors, walls and roofs, so it is not surprising to see it being used by some designers of hydronic systems. One of these innovative hydronics applications is the cast-in-place radiant wall systems for both heating and cooling that Regina-based MacPherson Engineering has been involved with.

The biggest challenge of using a cast-in-place system instead of a more traditional radiant panel system for heating and cooling is the coordination of the project, says MacPherson Engineering’s Heric Holmes. “With a panel system, because you put the panels in afterwards, you have less issues with coordinating things like anchoring, but it is a challenge because it takes a lot more effort up front to make sure the panels are built correctly before they’re installed.”

i>An economical choice

“The biggest advantage of using that system is the mobility,” said Heric Holmes, senior engineer at MacPherson. His company designed a caston-site radiant heating and cooling wall system for the Regina Provincial Correctional Centre (RPCC); where three wings of the century-old prison were replaced with a 216-cell facility.

Cast-on-site was chosen for the Regina Provincial Correctional Centre because it was a cheaper alternative than casting the walls in place, or bringing them in as pre-cast. This was due to the availability of a pre-cast plant and the ability to design most of the walls in a uniform manner, allowing for a lot of duplication. Since the walls were being built away from the core of the building in a heated storage shed, they did not interfere with the construction of the building, and were not affected by poor weather conditions.

i>Building the panels

The panels used were built by attaching PEX piping to rebar mats with six-inch spacing. The design was a four-pipe system with separate heating and cooling supply and return lines. The mats were then transported to steel forms, where any necessary embedding would take place and the concrete would be poured. After the panels were cured, they were

M e c h a n i c a l

B u s i n e s s

“Because the walls were cast-on-site, we could easily assemble the building and we didn’t have to worry about trying to tie anything to the floors,” said Holmes. “It was all embedded in the walls. As the building went up, we just built the structural walls around it and put the walls into place. It really sped up construction time and still allowed us to use radiant systems.” Another advantage of the cast-in-place system is better control of moisture. “For cooling, for example, you’re not as susceptible to condensation because you’re not having exposed metal to the air,” said Holmes. “Concrete has the ability to retain moisture. In order for moisture to appear on the surface, concrete has to be saturated. With steel there is no ability to retain moisture, so there is little forgiveness for problems with moisture control.” Cast-in-place radiant systems also allow for any embedding that might be necessary. In the example of the correction centre, the design called for anchoring metal beds to the walls, which they were able to embed into the panel systems by installing welding plates during the casting phase, and continues on page 56

tagged and moved to a storage area to be installed as needed. The panels would then be lifted into place via crane or forklift, and welded into position. “It was like a big jigsaw puzzle,” said Holmes. “Piece 1-A goes into spot 1-A type of deal.”

i>Protecting the system

Since the system is designed to provide both heating and cooling, the design team incorporated a deadband to avoid cycling the system directly from heating to cooling, and viceversa. Additionally, a 35 per cent glycol solution was used to protect against the harsh Regina winters. “In this case, our air handling systems are glycol-based and because they’re on an exterior wall, if there was ever a problem with the system we didn’t want to end up freezing the panels up,” explained Holmes.

i>Warm up and be flexible

Holmes recommends that contractors who are performing installs in the winter should look for a warm place to work on the piping. “In our case we did it in an indoor building, just to get the heat up so you wouldn’t be doing it while it’s really cold outside,” he said. “That allows the flexibility to build the panels and bend the piping in the middle of winter. In some environments that’s not a critical issue, but in Regina it definitely is… since it affects the malleability of the piping that you purchase.”

then welding the beds to these, before the panels were installed onto the building. “Items that need to be anchored to the walls, like the metal beds, need a place for mounting,” explained Holmes. “In order to not hit the piping while anchoring things like beds, plates are installed so that these items can be welded without damaging the walls. Direct anchoring could be achieved by x-raying the walls to find the loops, however, this is expensive.” According to Holmes, this works well when it is used for a building where construction is relatively uniform, has large surfaces of available wall space, and a stable occupancy load, such as gyms or classrooms. “Something with a lot of turnover like an office building, it doesn’t really suit that.”

Finding acceptable IAQ with

ASHRAE 62.2-2013 A cceptable indoor air quality (IAQ) is dependent on many factors, including indoor pollution sources, construction materials, furnishings, lifestyle of occupants and outdoor air quality. Acceptable IAQ is also impacted by the occupants’ tolerance to indoor pollutants. ASHRAE 62.2-2013 should be used as a starting point for the design of a ventilation system. As ASHRAE 62.2-2013 becomes more prevalent in local and national residential building requirements, it is helpful for everyone involved to become familiar with the basic ventilation requirements of this standard. ASHRAE 62.2-2013 calls for two mechanical ventilation methods: “wholebuilding ventilation” and “local exhaust.” Both methods need to be used to help achieve acceptable indoor air quality. And keep in mind that ventilation equipment is to be rated in accordance with HVI procedures. Remotemounted fans are not required to be tested or rated for sound.

THE STANDARD ASHRAE Standard 62.22013 is a ventilation standard that defines minimum requirements for ventilation systems. The goal of this standard is to achieve acceptable indoor air quality (IAQ) for typical residences. This standard is applicable to single-family

Whole-Building Ventilation ASHRAE 62.2-2013 has provisions for three basic mechanical ventilation strategies that can be used for Intermittent or continuous whole-building ventilation:

1. Exhaust ventilation 2. Supply ventilation 3. Balanced supply and exhaust ventilation

houses and multi-family structures of no more than three storeys. The standard does not apply to transient housing such as hotels or dormitories.

When selecting the whole-building ventilation strategy that is best for an application, consideration should be made for local code requirements, geographic location, special needs of occupants, and specific indoor and outdoor air quality issues. ASHRAE 62.2-2013 assumes that all buildings are tight and, as such, does not allow for the default assumption of two cfm per 100 sq. ft. that the previous editions did. Rather, it requires the use of a blower door to estimate the annual leakage. continues on page 62

TECH TIP The airflow of all installed ventilation equipment that is used to achieve the whole-building ventilation rate must be measured with an appropriate airflow measuring device.

High-perforance VENTILATION HVAC continued from page 60 For continuously operating ventilation systems, ASHRAE 62.22013 provides simple formulas and tables that can be used to determine the minimum whole-building ventilation rates. This minimum ventilation rate is based on the square footage of the dwelling and the number of bedrooms. The number of bedrooms is used to determine typical occupancy levels of the dwelling. This whole-building ventilation rate can be considered the required mechanical ventilation rate. Alternatively, the whole-building ventilation rate may be reduced by up to two-thirds to account for the effective annual average infiltration rate (Qinf). ASHRAE 62.2-2013 provides equations and weather data and describes various methods of testing to determine the Qinf for a specific dwelling.

Call us to learn how vänEE systems can improve your life!

A local mechanical exhaust system is required to be installed in each kitchen and in each bathroom. This local system can be designed for either continuous or on-demand controlled operation. The airflow of all installed ventilation equipment that is used to achieve local exhaust rates should be measured with an appropriate airflow measuring device. Alternatively, the airflow rating of ventilation equipment at 0.25” w.c. may be used if the prescriptive duct sizing of ASHRAE 62.2-2013 is followed. The airflow rate of local exhaust systems can also be applied to the required whole-building ventilation rate requirements, as long as they operate automatically. For on-demand operating exhaust systems, the minimum airflow rate is 50 cfm for bathrooms and 100 cfm for kitchens. For continuously operating exhaust systems, the minimum airflow rate for bathrooms is 20 cfm. The minimum airflow rate for kitchens is to result in five air changes per hour (based on kitchen volume).

For intermittently operating whole-building ventilation systems that run at least once every three hours, the time average ventilation rate cannot be less than the continuous ventilation rate.

For multi-family buildings: 1. Reductions to the mechanical ventilation rate due to effective annual average infiltration rate (Qinf) are not permitted. 2. Common areas are to be ventilated at a rate of 0.06 cfm per sq. ft. 3. Non-residential areas of mixed use buildings are to use ASHRAE 62.1.

Working with existing buildings For existing, occupied, buildings that do not meet the provisions of ASHRAE 62.2, an alternative method of compliance is available.

1. Local exhaust • If existing exhaust ventilation equipment in bathrooms and kitchens does not meet the minimum airflow requirements, the whole-building ventilation rate can be increased to offset the insufficient local exhaust airflow. • Existing exhaust ventilation equipment in bathrooms and kitchens does not need to be tested to AMCA standards or rated to HVI procedures. • If exhaust ventilation equipment is replaced in bathrooms and kitchens, this equipment needs to meet all requirements of ASHRAE 62.2-2013.

4. Common parking garages that adjoin occupied spaces are required to have exhaust ventilation at a rate of 0.4 cfm per sq. ft. 5. Specific steps need to be taken to minimize the air that is transferred between dwelling units. 6. The following requirements are in place to prevent air transfer through the ventilation system: • Exhaust fans in separate dwellings shall not share a common exhaust duct. • Exhaust inlets from more than one dwelling can use a single exhaust fan if the fan is located downstream of all of the inlets and the fan is run continuously, or if each inlet has a backdraft damper. • Supply outlets to more than one dwelling can use a single supply fan if the fan is located upstream of all of the supply outlets and the fan is run continuously, or if each outlet has a backdraft damper.

2. Whole-building ventilation • The required ventilation rate for existing buildings may need to be increased to offset insufficient local exhaust. • For existing buildings, if the calculated required airflow rate is less than or equal to zero cfm, no whole-building ventilation fan is required.

Booster pump retrofit targets energy savings

hen municipalities do energy audits looking for ways to reduce costs associated with building operations, most tend to target lighting and HVAC loads, since those are generally numbers one and two on most lists of energy spending in commercial buildings, but the plumbing systems can be a good target as well, in some cases. The city offices in Oshawa, Ont., are a prime example of what can be done with a little modern technology to improve system performance – and reduce energy costs – beyond the light ballasts and boilers. The administrative offices at the city are in a nine-storey commercial building serving almost 300 personnel. The plumbing system serves a pair of washrooms on each floor – three on some floors – and kitchenettes on each floor as well. The original domestic water delivery system used a constant-speed 120 USgpm booster pump that produced 140 psi of pressure, regardless of the demand for water in the building. The system was also using pressure reducing valves to throttle flow, but that wasted much of the pressure the system was producing. To think of it like a car, the system had the gas pedal to the floor and was using the brakes to control the speed. In addition, if the pump discharge hit 100°F or higher, due to low flow or excess pressure, a solenoid valve would open to release the water to drain. “Our previous system had two constant-speed pumps, which alternated operation daily. Each pump was 10 hp, 120 USgpm,” explains Charlie Drake, the city’s manager of operations and maintenance. “These pumps cycled often during off-peak times, and excess pressure was relieved to drain.”

Downstream benefits In addition to energy savings from better matching pump speed and system pressure to actual demand, the combination of lower speeds, the ability to shut down when no flow is needed, and the use of an automatic process that increases operating speed gradually as the system reaches a fill setpoint, helps to reduce wear and tear on the overall system, which reduces maintenance needs and extends the service life of components.

Matching the pressure to the demand The City of Oshawa, Ont., worked with consulting engineering firm Crossey Engineering to investigate options to replace its constant-speed domestic water supply booster system. The firm put in an Armstrong Design Envelope IVS booster system, a variable-speed unit that monitors pressure so that it can adjust the pump speed as needed to maintain system pressure, rather than the fully on or fully off operation of the former system. The new booster pump system no longer has need for pressure reducing valves and is designed to operate at 85 psi. Looking at the performance data, the building manager reports that the variable frequency drive has allowed the pump speed to be reduced to between 50 and 70 per cent during peak hours, and to less than 50 per cent most of the time. When no flow is required, the pump switches to a sleep mode rather than wasting water through a valve. “We’ve dropped our system pressure from 140 psi to 85 psi with no complaints,” says Charlie Drake. “And our pumps run at less than 50 per cent speed, so our electrical savings will be noticeable.”

How to

get awaywith

oversizing (Sometimes) A

lmost everyone has parts in the truck, or in the shop that might be too big for a particular job, but what happens when you are caught in a pinch, say when the right replacement item is out of stock, or you are in a mechanical room at 3 a.m. on a Sunday night with nary a wholesaler in sight. Are there parts of a hydronic system that can be safely oversized, and what problems occur when other components have been oversized?

I would argue that regardless of whether a component can be oversized, doing so will just increase the cost of the job, and the cost and complexity of maintenance and replacement. In general, size things correctly, per the design. However, in a pinch, the following guidelines may apply.

What not to oversize Boiler Keep in mind that boilers, even when “correctly sized” for the heat loss at design conditions, are oversized for most of their running time. We size for a worst-case temperature, which by definition of “outdoor design,” occurs only three per cent of the time. So if you oversize a boiler, you’re creating a situation where the boiler will always cycle excessively. Cycling a boiler heavily wears a lot of components (ignitors, ignition modules, pumps, circuit boards, fans, etc.), and wastes fuel, since combustion appliances aren’t at their most efficient upon ignition.

Indirect DHW tank While oversizing a hot water tank may seem like something that covers the homeowner in case of high load, consider this: the larger the tank, the slower the recovery. If you excessively oversize a storage tank, not only are the standby losses higher, but the recovery takes a big hit too. Having slow recovery means that once the tank is empty the homeowner gets cold or lukewarm water until the tank is given a chance to recover.

Pumps Pumps are among the worst things to oversize because they mess with the main design requirement: flow rate. Large changes to flow rate can often mean that emitters don’t work as expected, and trying to serve different loads simultaneously might just not work at all, since one part of the system could steal all the flow. Furthermore, oversized pumps also increase velocity, which can cause excessive wear on pipes and other components (think erosion – it’s very similar). continues on page 72

What not to oversize

www.hi-velocity.com

Small Duct High Velocity Heating, Cooling and Indoor Air Quality Systems

Piping I have yet to see anyone oversize the piping enough to make a difference, and it generally doesn’t occur because of the cost of pipe and the inconvenience of working with and stocking large fittings. That being said, it is possible to size pipe so large that there isn’t sufficient water velocity for smooth flow, which actually impedes heat transfer. I thought I’d mention it as a point of interest.

Small Diameter Flexible Duct Fits in Confined Areas with No Major Remodelling

Differential pressure bypass The main problem with oversizing pressure bypasses is that the flow rating range of the bypass won’t match the application, meaning that in certain conditions, the bypass just won’t work at all. Either the bypass won’t let any flow through if it’s oversized (the flow isn’t enough to push against the spring), or will let as much flow through as it can (if it’s undersized), but that won’t be enough for proper system operation.

Mixing valves I’ve seen these oversized rather frequently, and it never seems to go well. Oversized mixing valves cause behaviour that is probably the most difficult to diagnose, because they will appear to work, and “cycle” frequently.

Zoning-Ready HE-Z Series Fan Coil

Oversized mixing valves tend to “hunt”, meaning they are constantly moving, opening and closing, trying to deliver the right amount of heat, but the heat delivery swings too rapidly for the mixing control to settle on one position. The practical result can be that the valve ends up being off more than on, and it doesn’t actually provide the heat that’s required, but the sensors or controls are fooled into thinking that a big rush of heat (even too much heat) was just sent to the load.

Many Attractive Vent Plate Finishes Available

Ideal for Residential, Commercial, Multi-Family, New Construction and Retrofit Applications

In the most extreme examples I’ve seen, the oversized mixing valves fail early because they get such a small range of motion that they eventually seize, which also destroys the coupling and/or the actuator as the motor tries to move the valve. Alternately, the actuator on them fails early because of the constant adjustment.

Oversizing emitters is a tricky thing to talk about because of the recent trend that advocates larger emitters to decrease operating temperatures and increase delta-T across the emitter. That is, if you size a panel radiator for a design operating temperature of 140°F instead of 180°F, you are “oversizing” the radiator, as compared to what used to be considered standard practice. These new trends aren’t “bad”, but require design adjustments. You continues on page 74

can’t just oversize an emitter without also adjusting other components to suit. When increasing the size of an emitter, and with all other things being the same, the following will change: • Minimum required flow; • Flow velocity; • Delta-T across the emitter; • Return water temperature; and • Pressure drop across the emitter. This article won’t cover what you have to change when increasing the size of emitters. Just remember that you’ll likely have to change other components (like pumps) to suit the new situation.

M e c h a n i c a l

The beautiful thing about expansion tanks is that they can be oversized pretty much infinitely. Your restrictions are only cost, and boiler room real estate – the second probably being the most relevant to most contractors. In short, the air cushion or bladder in the tank is built to absorb up to a certain amount of movement, and if you don’t use all that movement space, there really isn’t any problem.

Air and dirt separators These are usually sized “as small as possible” because of cost, but if you happen to oversize them slightly, they actually just work better. The lower the velocity of flow inside the separator, the easier the air or dirt drops out of the flow and can be filtered out. The only issue then becomes the bushings or fittings you have to use to accommodate the larger separator.

Zone valves Large zone valves are expensive, so these are hardly ever oversized. Yet, they can be oversized quite readily if needed, and the only impact is a reduced pressure drop across the valve, meaning that the pump will provide slightly more flow. Taken to an extreme, or in a large application, the resulting increase in flow could increase fluid velocities above recommended levels, but generally the change in flow is minimal on a pervalve basis. Most of the time, zone valves can be safely oversized in a pinch.

COVER STORY

By Andrew Snook

lthough Darryl Sittler wore No. 27 throughout his tenure with the Toronto Maple Leafs, the former captain is more synonymous with the number 10 in some hockey circles. The former Maple Leafs captain has the distinction of holding one of the most prestigious NHL records to this day for his 10-point night more than 38 years ago, when he tallied six goals and four assists against the Boston Bruins in an 11-4 rout.

When asked if he thought his 10-point night against the Boston Bruins would have stood the test of time against all the stars that have come and gone over the past 38 years, he says the possibility of sharing his record was definitely there. “Especially when Wayne Gretzky was getting in excess of 200 points and Mario Lemieux was playing,” he says. “They were both such great players, and great offensive players. They both got eight points, but nobody has got nine or 10. I think it’s obviously going to be a difficult record to beat. Nowadays, even though there are so many great players in the game, I think that if you look at the scores, very seldom do you see six, seven goals by one particular team anymore.” Although his 10-point night was one of Sittler’s biggest career-defining moments, it isn’t his most memorable. For him, that was winning the Canada Cup in 1976, scoring the overtime goal against the Czechoslovakian team. “I was playing on Team Canada with one of the greatest teams Canada ever put together,” he says. “Bobby Orr was on that team, Bobby Hull, Guy Lafleur. I think 19 guys from that team went on to be inducted to the Hockey Hall of Fame.”

Banner Raised

He says being inducted into the Hockey Hall of Fame in 1989, and later, having his No. 27 raised to the ceiling of the Air Canada Centre in Toronto were also defining moments in his career. “It was very moving because I had lost my wife to cancer a couple years before that, and I asked the Leafs if they would put her name on the banner, which they did. It was a very emotional night for me, my children and all the fans watching at the game and at home. Wendy was a major part of my career and my life, obviously, and it was nice that her name was on the banner when it went up.”

Assisting others

The Winter Classic

One of the ways Darryl helps out the community where he played most of his career is by sitting as a board member for the MLSE Team Up Foundation, alongside fellow former Maple Leafs captain Wendel Clark. “The whole purpose is to create opportunities for the youth around the Greater Toronto Area,” Darryl explains. “Part of the charity refurbishes rinks, basketball courts and soccer fields. The other part is about raising money to send kids to camps and give them an opportunity to participate in sports.” Sittler has participated in the foundation’s work since its inception. “My role over the years has been more of an ambassador,” he says. Although he isn’t as involved in the hockey side of the Leafs organization as he used to be, Sittler still loves to slap on his skates whenever he gets the opportunity. Since losing his wife to colon cancer 12 years ago, Darryl has also been active with Screen Colons Canada, a charity that raises awareness about the prevalence and preventability of colon cancer while promoting the screening of all Canadians who are eligible through age or risk. He raises funds for the organization through the Darryl Sittler Smart Ass Golf Tournament, which was held the past few years in June at Glen Abbey Golf Club in Oakville. His is also a celebrity ambassador for Colon Cancer Canada.

The Toronto Maple Leafs had the honour of participating in this year’s NHL Winter Classic on Jan. 1, defeating the Detroit Red Wings 3-2 in a shootout at a packed outdoor rink in Ann Arbor, Mich. It was the first time the Leafs have been involved in one of the NHL’s outdoor games, and the first one for Sittler. Although Toronto’s team ended up losing both of the NHL Alumni Showdown games to the Red Wings, it didn’t prevent Darryl from enjoying the festivities. “It was a wonderful experience all three days,” he says. “Lanny McDonald, Tiger [Dave Williams] and I took our grandsons down, and they hung out with us, which was great.” The NHL has made a statement of sorts, showing that the climate can be overcome, in many instances, with a bit of mechanical magic, putting on outdoor games in Michigan, New York, and even sunny California this year. Weather still has an influence on the game, however, says Sittler. “The ice can be a little chippy and brittle,” he explains. “But for the most part it was pretty good during our game.” Elements like wind and snow can also play key factors in outdoor games. Fortunately, the weather cooperated for Sittler’s game. “It was a pretty nice day, actually. The sun came out at times,” he says. “The other nice thing was that the benches had heaters on them so they were pretty comfortable. We had six lines, so it wasn’t like you got a lot of ice time, but you got to shoot around with everybody, which was good.”

Hockey’s handyman Although Darryl was able to build an illustrious hockey career over his 15 years in the NHL, it wasn’t his only focus growing up. While playing junior hockey, Sittler was enrolled at Fanshawe College, where he took a construction technology course, following a similar path to his father who worked as a crane operator. Whether it was helping someone take down a wall in a house, build a deck or interlock a stone path, Darryl has always been happy to work with his hands and pick up the tools. “I’ve always been a handyman, doing my own things,” he says. “I don’t do as much today as I did before, but I’ve always enjoyed it. I can do the odd plumbing job – fix clogged pipes, or solder some joints.”

Whatâ&#x20AC;&#x2122;s a backwater valve? Many people interchange the terms backwater and backflow when it comes to the devices used to protect a building or water supply, but they are in fact different types of protection.

ven prior to the flooding experienced in several parts of the country last summer, a number of Canadian municipalities had put in place, or were discussing, bylaws mandating the use of backflow and backwater valves to protect against sewage backups and to protect public drinking water. Some municipal building codes require a backwater valve if a homeâ&#x20AC;&#x2122;s plumbing fixtures are below the top of the first upstream manhole on the street, and even where bylaws donâ&#x20AC;&#x2122;t require the valves, many cities are advising for the use of the devices to protect a home from basement flooding due to water from floor drains. One of the dangers, even with small localized floods, is that there is a risk of sewage from sanitary sewer lines backing up into houses through drainpipes. This sewage water can cause damage to the structure and personal property, as well as have a negative impact on health of the inhabitants. A backwater valve can help combat this risk.

A backwater valve is designed to prevent the contents of drains and sewers outside the home from backwashing into the home, which can happen when flooding reverses the pressure and flow in a municipal sewer system. A backflow device is designed to protect the potable water supply from cross connection contamination. This may occur, for example, when a hand shower is left lying in a bathtub filled with water. Without a check valve, air gap or backflow device, the greywater from the tub could flow into the potable supply line if a reversal of the normal pressure difference in the plumbing system were to occur. A properly operating backwater valve allows flow to only go in one direction, out, preventing wastewater from entering a building during regular sewer system maintenance or accidental sewer system backups.

Adapting to pipe types

An ounce of prevention If sewage backs up into a home, the cost to repair damages and clean up the mess may be considerably higher than the cost to install a valve.

In some installations, it may be necessary to adapt the plastic backwater valve to work with clay or cast iron pipe. Neoprene rubber adapters are available to make these transitions. These clamp to the outside diameter of the pipe and the backwater valve with stainless steel clamps and sleeves. Different plumbing codes may require different models of adapters, so check the local municipal code to ensure that a proper adapter is used for the application.

Proper installation is critical The first step when installing a backwater valve is to consult with the local codes and ordinances. Knowing the requirements can avoid the possibility of having to tear out and reinstall the unit.

Give us your feedback and you could WIN an iPad Air

The next step is to consult the installation manual for the valve that you are installing. Valves will take up a certain amount of space in the drain line, and the outlet will be lower than the inlet, all of which will need to be accounted for.

Visit our booth for details.

Booth 2241

One of the more popular backwater valves on the market is designed to take up 12” of run in the drain line. The outlet is 3/4” lower than the inlet so in 12”, the level of the pipe at the outlet side needs to be 3/4” lower. Depending upon the amount of slope in the line, and knowing that a minimum of two per cent (2%, or 1/4” per foot) is required for proper operation, it may be necessary to replace several feet of pipe upstream from the valve to average out this loss of 3/4” of fall.

recycle - reuse - save greywater recycling system

In order to achieve a minimum slope of two per cent through the valve in a retrofit installation, it will likely be necessary to expose four or five feet of pipe. And since many sewers are flat or backgraded, it may be necessary to adjust the grade on the piping leading up to the valve to achieve the required slope through the backwater valve.

M e c h a n i c a l

Another option available to the industry that is getting traction, and may be better suited for retrofit applications where slope is a concern, is a normally-open design automatic backwater valve that uses a ball to activate the valve. This can be easily retrofitted with less piping to be exposed. Some valves are extendable and are designed for deep burial, so they can be installed outside of the foundation, rather than inside the premises.

When installing: • In retrofit installations, always run and test all fixtures to ensure each one runs through the backwater valve, and nothing remains unprotected. • Check that the sewer is unrestricted, and that there are no roots or other blockages downstream of valve. • Ensure that weeping tiles tie in downstream of the valve. • No branch take-offs may be made closer than two feet upstream of some backwater valves. This helps to ensure a laminar flow of effluent over the gate of the valve. Check the manufacturer’s specifications. • Follow installation procedures carefully, taking special care when retrofitting a valve into existing systems. • Be sure that no glue or solvent comes into contact with the valve’s gate or sealing surface. • Be cautious when back-filling or adding concrete near the valve, so as not to deform the valve body. • Consider the grade when installing any valve, and do not install the valves if the proper grade cannot be achieved. • Be aware that improper installation may result in valve failure.

Don’t forget the maintenance • Some valves have a clear top for easy inspection and maintenance. • As with any mechanical device, periodic inspections and cleaning will be required. Proper maintenance and cleaning will help ensure that the valve is ready should a flood occur. • Regardless of the type, it is important to inspect the backwater valves thoroughly and check to ensure that the gate moves freely without resistance. If it does not, repair or replace the device. • Look for debris build-up on the body, gate and beneath the gate. If debris is found, simply flush the area clean. • O-rings should be inspected and replaced, if necessary. On models fitted with closed cell polyethylene floats, check the condition of floats and replace them as necessary. • And don’t forget to reinstall the cleanout plug once the inspection and cleaning has been done.

Managing

ammonia leaks R

efrigeration technicians are sometimes required to respond to a variety of jobsite leaks, which can range from minor industrial issues, such as packing gland leaks, to less frequent, but more dangerous leaks where additional emergency service crews can be required. Since the phase out of R-22 in 2010, many large industrial facilities, such as bakeries, have been looking at going back to ammonia-based systems for their needs, says Tony Panetta, training and service support specialist for Cimco Refrigeration. This means technicians should make sure they have a solid game plan ready, now more than ever, to make sure they are prepared to deal with a potential ammonia leak. “I think in times to come, with the phase out of CFCs, and HCFCs coming soon, I think there’s going to be a lot of attention given to ammonia, a lot more attention.”

Look for a plan “Preparedness is important,” says Panetta. “I think a large plant, like a brewery or a meat packing plant, will need to look at something like that, so they gather some sort of preparedness for the employees and maybe for the response team as well.”

Assessment process The first step when a leak is reported is to clarify the notification coming in, and quantify the leak, if possible. Doing a physical assessment is recommended as well, says Panetta. He says technicians should rely on the information the people on site are relaying, but at the end of the day the assessment is going to be the technician’s, as well as those that are working with him. This group could include the plant operating engineer, the plant maintenance people, and possibly other emergency responders. “Sometimes perceived major leaks are called in by the fire department,” says Panetta. When a technician arrives at the scene of a potential ammonia leak they should first perform a situational assessment.

“That’s what we teach in haz-mat,” says Panetta. He says that most calls are for minor leaks. “Just like with halocarbons, you know packing glands are going to leak and maybe an open drive mechanical shaft seal might leak a little bit,” he says. “I think that’s where the majority of the ammonia releases would be.” When major leaks do take place, unless the technician is trained at a high level, they should back off and work with other emergency responders, he adds. For quantifying the concentration, rely on detection equipment whenever possible. “There are gas detection devices in the machinery rooms,” says Panetta. “When we can rely on those, it makes assessment easy.”

UV-C for energy efficiency Coil Cleaning Equipment manufacturers usually recommend coil cleaning twice a year and no less than annually to prevent mould growth and capacity loss. With staffs and budgets shrinking, however, time and money for in-house or contracted coil cleaning is becoming scarce. In fact, some building operators report they have not cleaned their coils in three or four years. If coil cleaning is not performed regularly, contaminant buildup deep inside internal surfaces can become so difficult to remove that expensive coil replacement becomes the only option. Performance losses from contaminant buildup have led many building operators to retrofit their air-conditioning systems with UV-C light systems. ASHRAE’s HVAC Application handbook recommends that UV-C irradiance levels should strike coil surfaces with 50 to 100 microwatts per square centimetre (W/cm²). A more understandable and convenient way to provide the recommended amount of UV is to use lamp watts, which is printed directly onto all major suppliers’ lamps. ASHRAE’s recommendation of 100 W/cm² works out to be slightly under 7.5 lamp watts per square foot of coil surface area, which equates to less than 0.015 watts per cfm.

M e c h a n i c a l

The president of UV Resources, Forrest Fencl is an ASHRAE Fellow, formerly an ASHRAE Distinguished Lecturer, and a member of the International Ultraviolet Association and the Illuminating Engineering Society. He can be reached at forrest.fencl@uvresources.com.

here are two distinctly different methods of applying ultraviolet-C energy (UV-C) in HVAC equipment. The first is surface irradiation of cooling coils, drain pans, and other interior surfaces of air handlers and plenums to maintain their efficiency and cleanliness. The other is airstream disinfection, which kills airborne microorganisms in supply air on the fly.

The most common of these is surface irradiation, which represents well over 95 per cent of the installs in North American HVAC equipment today. The benefits of UV-C surface irradiation systems include maintaining indoor air quality and comfort levels commensurate with the owner’s performance requirements of the HVAC system, and doing so with minimal wasted energy. For new construction, UV-C systems maintain as-built conditions from the very beginning. For retrofit applications, UV-C systems remove organic growth on coil surfaces on the outer and inner layers, and similarly, clean drain pans and other interior surfaces. As air conditioning equipment ages, its ability to maintain adequate space temperatures and humidity levels declines. Most often, the culprit is reduced coil heattransfer effectiveness, or the ability of the air handling unit’s cooling coils to remove heat from the air. Evidence shows this drop in performance can occur within five years of startup, due to the buildup of contaminants on

B u s i n e s s

0 4 . 1 4

coil surfaces. This accumulation of organic material causes higher leaving-air wet-bulb temperatures, meaning an AHU is removing less total heat (sensible and latent) from the air and, as a result, the space temperature and humidity is elevated.

Design considerations For surface disinfection systems, the goals of a successful UV-C system are: • Achieve ASHRAE-recommended minimum levels of surface irradiation (dose); • Require the fewest number of same-size lamps (lowest first cost); • Easily inspected and serviced (lowest operating cost); and • Properly controlled for safety (a basic requirement for any system). Additionally, coil pressure drop levels are higher and, especially with constant-volume fans, airflow levels are reduced. continues on page 92

A SIMPLE AND FLEXIBLE SOLUTION FOR VENTING MULTIPLE POLYPRO LINERS

NEW Approvals

High-performance HVAC HVAC continued from page 90 Of course, there are energy and other cost penalties associated with coil fouling, such as chilled water systems consuming more energy to compensate for lost capacity. These result from lower water temperatures and/or additional water volume as may be needed to achieve reasonable off-coil temperatures, along with the servicing of occupant complaint calls. When airflow and coil temperature differentials decrease there is a corresponding decline in HVAC system capacities. Even small changes can have a dramatic effect on cooling capacity. Therefore, both must remain at as-built conditions for a system to perform as designed.

Need to run multiple flexible liners in a single chimney or B Vent space? Do your installations have an endless variety of flue sizes and conduit sizes? M&G DuraVent’s new solution for venting multiple PolyPro flue (flex or rigid) provides a simple and flexible solution. For support, M&G DuraVent simplifies the installation by using a new reline hanger support. The reline upper plates finish the install and provide a water tight seal. A great combination when you need to vent multiple appliances within the same space. All PolyPro terminations and components are listed.

Sizing

for proper dosage UV-C lamps are sized for delivering a particular amount of light (irradiation) on a surface – i.e., a dosage. Dose is the amount of energy absorbed by a microbe, which, mathematically speaking is the product of time and intensity. Ideally, intensity is what comes out of the lamp, however in practice, such factors as air temperature and surface reflectivity work to decrease and increase dosage, thus requiring the application of de-rating factors in sizing calculations. After taking into account all of these factors, the dosage goal is to yield an irradiation dosage of 7.5 lamp watts per square foot of coil surface area. This ASHRAE recommended wattage level applies to all areas of a coil’s surface, including the far corners. If a greater dosage is achieved, this is actually desirable because it provides additional airborne kill. This is a situation where “too much” does not adversely impact system components. Achieving a UV dose that is 100 W/cm² at the farthest corners of a coil will result in higher UV-C irradiation levels in the centre of the coil. Since a larger percentage of the air goes through the centre of the coil, the airborne kill ratios are higher there than in the corners.

Incorporating UV-C

Lamps and lamp life

into the system

Most lamp manufacturers list a UV-C lamp’s “useful life” as 9,000 hours, which is conveniently close to the 8,760 hours that are in a year.

UV-C lamps are typically installed horizontally 12” away from the coil’s surface, however 15 years of experience has verified that distances ranging from three-inches to 30” will work. UV-C systems are most often installed downstream of the cooling coil in the direction of airflow. This is favoured because the air there approaches saturation, meaning that within this plenum, there could be raw water, damp insulation, and other conditions that are known to lead to the growth of mould and some forms of bacteria. Also, coil drain pans are often extended in this location to catch raw water carryover from the cooling coil.

At 9,000 hours, lamp output begins to fall to 85 per cent or less of the original output. Because the blue hue produced by the lamp is not indicative of the invisible UV-C energy output, lamp manufacturers are generally not willing to guarantee useful UV-C output for longer than 9,000 hours.

UV lamps are available in lengths ranging from 24” to 60” (60-145W), and lamps are typically overlapped in the plenum to reduce the number of sizes used on a site. Doing this, the designer can often use a single lamp length, which will minimize both first cost and replacement costs. As for power and control, a connection to 120/240/277Vac power fed through a toggle switch outside of the plenum and door interlock cut-off switches are the basic installation criteria. Check the manufacturer’s IOM details for how to secure the lamps in place for easy lamp installation and replacement. UV-C systems should be designed with door interlocks such that when air handlers are opened the UV-C lights will automatically switch off. Warning labels should be placed on air-handler doors. Additional controls can include lamp and ballast monitors, alarms, and radiometers. These types of controls are more typical for infectious disease applications where the1highest output must be Mechanical Business 7" 4 7-8" February 5, 2013_HR.pdf 2/12/2014 4:30 PM maintained on a continuous basis.

Also, running lamps longer will usually produce lamp outages one at a time, causing service personnel to have to inspect them more frequently to know what to replace. This is inefficient and expensive. Replacing lamps only as they burn out also requires added inventory. Most hospital and building management groups report that they prefer to set up an annual preventative maintenance schedule for lamp replacement.

Hydronic Case Study

B y B ar r y C am p b ell

Windsor goes radiant KeepING it Clean “The team looked at 10 different designs and narrowed it down to six or seven methods of doing in-floor heat,” said Frank Frabotta, partner at Baymar Supply in Windsor. “If the manifold had not been polypropylene, it would have had black pipe installed above the floor.” While the hybrid system was able to meet the hangar’s heating needs, contractor Lou Panontin said there were concerns about air infiltration from the motor-driven 40-foot tall panel doors and the spaces between the panels.

for hangar

Hybrid design delivers significant space savings and simplifies PEX circuit layout and installation.

perated by the City of Windsor since 2007, Ontario’s Windsor Airport serves a mixture of scheduled airline flights and general aviation, and is a popular point of entry into Canada for private and business aircraft. In 2011, the City of Windsor identified the need for a new service hangar at the facility in order to increase air traffic revenue, create more jobs and diversify the local economy. The project’s design team had to address several building fundamentals based on the nature and location of the project. The 92,000-plus sq. ft. hangar is 79 feet tall at its highest point and can accommodate a Boeing 737, so it was essential to design an HVAC system that could provide consistent, comfortable heating for service technicians in frigid winter temperatures, as well as one that wouldn’t interfere with the movement of aircraft in and out of the facility.

“We wanted to make certain that when bringing a plane in we could combat that infiltration – you can see daylight through some of these cracks,” he explained. “Just about the entire facility is heated with radiant heat, but we decided to install four indirect gas-fired heaters – one in each corner.” Thus, four Engineered Air 80% efficient 600,000 BTUH indirect gas-fired heaters were deployed.

M e c h a n i c a l

Serving as project administrator for the city’s engineering development department at the time of the hangar’s construction, Tom Graziano worked with the hangar’s tenant, Premier Aviation Windsor, to deliver on some very particular design needs. The tenant had specifically requested an in-floor heating system that could maintain

Core”

consistent indoor temperatures, especially with the opening and closing of the large hangar doors in the winter. According to Graziano, while the city had not set specific energy efficiency parameters for the project, they did want to specify an HVAC system that could deliver on their tenant’s request, as well as perform optimally and costeffectively. Based on this criteria, Graziano investigated the cost of an in-floor radiant

heating system, since it would maintain the indoor temperature by heating the building’s core mass (in this case, a concrete floor) rather than blowing hightemperature air intermittently via a forced air heating system. Although the installation cost of an in-floor radiant system was higher than a forced air system, the energy savings and comfort benefits ultimately prevailed. Several competing in-floor heating designs were presented for the project, and eventually a hybrid HVAC design incorporating Aquatherm Blue Pipe polypropylenerandom (PP-R) and Rehau RauPEX crosslinked polyethylene (PEXa) pipe with oxygen barrier was selected. “Radiant heating provided an ideal solution for this particular project, as it eliminated the need for potentially intrusive ductwork and overhead heaters in the building,” said Stephan Meindl, sales rep for Torontobased manufacturers’ representative firm Mech Tech Marketing Inc. “In addition,

the system’s ability to provide even, consistent temperatures would be of benefit in regard to quick, efficient heat recovery when the hangar doors were opened and closed.” “The performance spec said that radiant heating was an add-on,” said Lou Panontin, P.E., president of Southern Mechanical Contractors Ltd., the project’s mechanical contracting firm. “I had initially offered indirect gas-fired heaters as an option. Due to concerns about infiltration, and savings over going with eight indirect gas-fired heaters on the ceiling and blowing the air down, radiant was a good option.” Panontin added that the ability to heatfuse the Aquatherm manifolds and place them within the concrete slab eliminated the need for tube heaters on the ceiling of the facility and the pipe to feed them. Additionally, the cost and safety concerns

M e c h a n i c a l

which would have been involved with using a scissor lift to install the tube heaters were no longer an issue. Including the snowmelt portion of the job, the pipe systems would be encased in the roughly 92,825 sq. ft. of concrete slab at depths of 16” to 24”. A total of 2,000 linear feet of PP-R pipe in sizes ranging from 3/4” up to 2-1/2”, along with 77,000 linear feet of 3/4” PEXa tubing with oxygen barrier, was used for the system. The hybrid HVAC system design incorporated reverse-return distribution headers and fusion saddles connecting the radiant heating system to a series of boilers, pumps, balancing valves, and expansion and glycol fill tanks. Due to their small footprint, Panontin chose to use two Aerco 1,500,000 BTUH high-efficiency condensing boilers to serve the radiant system. continues on page 98

[ Keeping it warm

outside too Keeping the entries to the bay doors clear of snow was an essential concern, so the designers extended the radiant system to include a snowmelt system that stretches roughly six to eight feet outside of each hangar door. The system used roughly 3,500 lineal feet of 3/4” PEXa pipe with oxygen barrier, along with a seven-loop manifold for each hangar door.

Heat-fused in Freezing Temperatures Following a half-day training session provided by Baymar, the installation began in October. Challenges with fusing the Aquatherm fittings to the pipe in the cold weather were solved by performing the heat connections inside a heated 40-foot construction trailer. Three to four lengths of 13-foot pipe were fused together and then removed from the trailer via a rear sliding window. Another challenge faced onsite was keeping machinery and workers off of the laid out sections of piping during installation. To resolve this, the installation was divided into three sections. This meant capping the headers, pressurizing the completed section, pouring the concrete then removing the caps and continuing to the next section. The cement contractor poured the concrete and left a 20-foot wide, unpoured space the length of the building where the two distribution headers would be installed. Three-quarter-inch through 2-1/2” dimension pipe was used for the reverse return headers (supply, return and the indirect return) which ran down one side of the hangar. A foreman and three Southern Mechanical installers completed the pipe and tubing installation in roughly eight weeks. “We tested it to 125 psi and we had no leaks,” Panontin said. “But after testing it at 125, we left it at 50 psi in case someone punctured the tubes. They did end up puncturing two circuits and we took those two out. So to have two leaks out of 149 circuits, which is less than one per cent, that’s not bad.”

Photos don’t lie The hangar’s massive 16” to 24” deep floor, which stores immense amounts of heat, proved to be extremely efficient. And from an owner’s standpoint, the installation went smoothly. “It’s a big space and a thick floor, so there’s a bit more involved with supporting the floor,” said Graziano. “Considering the magnitude of the job, it went at least as quick as I expected it to, if not quicker.” After serving as the sole source of heating during construction, the system went live in November 2011. Graziano reported that while the 2011-12 winter was rather mild, the system provided comfort and functioned as expected, and that during the 201213 winter, Premier Aviation Windsor reported that the hangar was even too warm at times. Additionally, Graziano said that while the supplemental Engineered Air units did turn on when the hangar doors opened, they have not yet been needed for general heating purposes. Thermographic images revealed that the floor is within an 8°F spread from one end to the other. According to Gordon Marentette, Baymar’s estimator/project manager, “There is very little variance – a one degree variance from one end to the other. The thermal images are so detailed that the headers and every pipe loop is visible, showing the continuity of the even heat.”

A battery of choices

The lithium ion battery is the fastest growing battery technology today.

lectronics are part of everyday life and are prevalent features in commercial restrooms where electronic fittings have become the norm. Electronic plumbing fittings offer sanitary, touch-free operation, while conserving water and energy, but there are several choices when it comes to power sources, including hardwiring, batteries and power-harvesting options, such as solar or turbine products. All have advantages and disadvantages, depending on the application. When sensing technology was first introduced, battery-powered fittings were often only used in building retrofits where it would be difficult to hardwire the fittings Today, battery-powered systems are used as often as hardwiring as they avoid the upfront cost of adding electrical wiring. Further driving acceptance is ever-increasing battery life, which extends the service interval and lowers the total lifetime cost of the product.

Battery Types All batteries have a set energy density, or capacity, from which power is drawn. High or low current needs, intermittent or steady drain, and temperature are all factors that impact battery longevity. In the case of plumbing fittings, restrooms typically have low current, intermittent drain conditions, and the temperature depends on the location. The most common type of primary battery is alkaline. The alkaline battery has a high energy density; long shelf life; and very good leakage resistance. Its lower internal resistance allows it to operate at high discharge rates over a wide temperature range. Alkaline batteries have a high rated capacity and deliver their full capacity if the power is used slowly. Under normal room temperature conditions, the battery will self-discharge at a rate of less than two per cent per year. However, if alkaline batteries are stored or used in higher temperatures they will lose capacity more quickly. For example, at 85°F, they lose about five per cent per year; at 100°F, they lose 25 per cent per year. Interestingly, if used under cooler 1102

M e c h a n i c a l

B u s i n e s s

climates, the capacity change is insignificant and really does not affect how long the battery will last. Since most plumbing fittings are installed in cooler places, alkaline batteries can be a good choice. One disadvantage of alkaline batteries is the possibility of leaking when they are discharged below 0.8 V. To minimize that problem, some sensors warn users of a “low battery” with an indicator light, and may even shut off after a number of activations. Lithium primary batteries are another good source of power for electronic plumbing fittings because they also provide excellent performance at lowto medium-current applications. The major advantages of lithium primary batteries over alkaline batteries are their good storage life and discharge performance. Operating temperatures have little effect on operating characteristics because the cell is very efficient. They also provide excellent performance at low temperatures. These batteries can be stored several years longer than alkaline batteries and they tend to have a smaller form factor, which permits more compact product designs. At a self-discharge rate of approximately 0.15 to 0.5 per cent per year, many lithium batteries have a 10- to 15-year shelf life and can last longer than alkaline batteries of the same capacity.

Reaping All the Benefits Strategically located in Montreal’s Ville Saint-Laurent, Les Jardins Montpellier is a nine-story residential complex with all the benefits of the dynamic atmosphere of the city yet with surrounding tranquility. The building features 72 units, including a ninth floor penthouse, and a lower level parking garage, swimming pool and gymnasium. Each of the luxury units features a washer and dryer area, state-of-the-art kitchen and elegant bathroom, all of which obtain water via the latest water distribution system from IPEX—AquaRise®. A solid alternative to metal, AquaRise delivers hot and cold potable water in commercial, industrial and high-rise buildings. This CPVC distribution system comes with reduced material costs and saves valuable time and money on job sites. Its proven strength, highly-engineered construction and robust fittings provide long-term performance, pressure rating and corrosion resistance for years of consistent flow and maintenance-free performance.

AquaRise is deployed for the riser distribution system throughout Les Jardins Montpellier. On each floor, it branches off to the apartment units where it transitions over to traditional PEX pipe. Because each unit includes its own hot water heater, AquaRise is used for cold potable water distribution only. The system was designed by Desjardins Expert Conseil (www.genieconseil.com), the mechanical and electrical engineer for the project who has been installing IPEX products for many years.

“AquaRise is very practical and easy to work with. We choose it over the higher price and trouble involved in installing and manipulating copper,” says Jean Desjardins, P.Eng.. “Time is money, and it takes more man power to carry and install heavy copper. We also use this product because it is approved for use with noncombustible buildings.” AquaRise transition fittings use a simple solvent cement system that make it faster and easier to assemble than soldering traditional copper systems. Desjardins also finds the assembly process to be safer and more reliable. “I prefer the process involved in assembling AquaRise over welding copper because we don’t have to deal with fire or safety issues on the jobsite,” he says. “And unlike copper, when we put the solvent material around the joints, we’re sure it’s going to be sealed. AquaRise is a great alternative—it’s about time someone introduced this type of product.” Like all IPEX integrated solutions, AquaRise pipe, valves and fittings are designed to function as a system, yet flexible enough to work universally with other products. Meeting the requirements of CSA B137.6, AquaRise passes the punishing burst pressure tests conforming to ASTM F442. And since it’s built and backed by IPEX, AquaRise also comes with superior technical support and jobsite trouble-shooting.◆

An additional battery technology used in some products is lithium thionyl chloride, equipped with a capacitor that collects small electrical charges every time the faucet is activated. This allows the cell to maintain its power storage. This hermetically sealed battery has a self-discharge rate of less than one per cent per year, so they should have a long lifespan, but they cost more when it comes time to replace the battery, which is a consideration for any facility manager.

Power

harvesting options

When batteries are used in electronic fittings that employ power harvesting, often solar or turbine technology, it’s an either/or situation. That is, the fitting’s first option is to activate via the harvesting technology. The battery power is only used as a backup for when the harvested power does not have enough juice to power up. This helps extend the life duration of the battery. Although both solar and turbine power harvesting technologies use batteries as a backup, they do not use the backup feature in the same manner. A key difference between solarand turbine-powered products is that the turbine-powered plumbing fitting must be used in order to generate any supplemental power. A fitting using solar technology only needs the battery to power the solenoid when a storage capacitor is drained. And only in rare cases will there not be enough ambient light to provide the energy the battery needs to power the fitting. A hydro-power turbine fitting relies on the battery for power when there is insufficient use to generate electrical energy or when there is not enough energy stored in the capacitors. This is not a problem in a busy restroom, but can be a concern in a facility that sees limited use.

Matching to the application Battery shelf life and service life are not the same. Maximizing service life entails recognizing and tapping into the strengths and weaknesses of each battery option. In essence, determining which type of battery to use depends on the application.

● AC/R Testing ● Building Performance ● Combustion Analysis ● Energy Auditing

High-traffic areas, for example, will consume many more batteries than a low-traffic restroom, unless they make use of a power harvesting method. Realistically, in the case of a high-traffic area, the benefits of using a battery with a longer shelf life may not pay off. Using it only gives a few hours more operating life and carries a higher replacement cost.

A low-traffic restroom, on the other hand, can take advantage of a battery with a longer shelf life, and combined with power harvesting techniques, it guarantees long service life.

Dealing with low charge Battery-powered plumbing products often include warning lights that indicate when batteries will soon need to be changed. Some battery-powered flush valves also have mechanical overrides that enable manual flushing when the batteries need to be replaced. If batteries are not practical, then hardwired fittings may be a better choice.

Popular this season Driftwood style log sets, ceramic spa stones and river pebbles.

nce used simply to provide warmth in a home, the fireplace has evolved from utility to become a fashion statement, and many of the latest gas fireplaces to hit the market offer the ability to merge both form and function, dressing up a room while providing supplemental or zoned heat. In addition to changes in styles, modern fireplace manufacturers are opening the doors to design options that would not have even been considered possible just a few years ago, from units that can be installed on exterior walls to provide an indoor and outdoor effect from a single

Unobstructed views

Contemporary fireplace design has moved to clean, linear lines with less metal and more glass, reports David Coulson, since consumers want to be able to see the full flame without obstruction. “Since fireplaces are considered a main focal point of a living space, it creates greater demand for a larger viewing area for the glass and the fire, with less exposed steel and trim,” explains Rachel Romaniuk.

designs that incorporate fireplaces in many creative new ways,” says David Coulson of Napoleon Fireplaces. In addition to outdoor units, designers are outfitting other non-traditional areas with the focal pieces, including fireplaces for bathrooms and kitchens. “There’s a lot more access to trendy magazines and home renovation television shows that showcase sleek fireplace looks,” adds Rachel Romaniuk, marketing coordinator with Regency Fireplace Products. “Today customers have access to affordable custom looks.”

“The clean face look is the latest trend for both fireplaces and inserts,” agrees Jeff Clare. The term clean face refers to a unit that does not have traditional louvers. “Often what the customer asks for is a combination of traditional log set and contemporary clean face style,” he adds. “A totally modern look would include porcelain combustion panels replacing the standard brick, contemporary logs such as driftwood and glass rocks.”

Looks, plus performance

Unlike in the United States, in Canada fireplaces do not have an efficiency performance requirement, says Jeff Clare of Redmond Hearth, but efficiencies are noted on a model’s rating plate, and many in the industry believe that it is just a matter of time before a performance requirement is introduced in this marketplace as well. What is used in Canada is the EnerGuide Fireplace Efficiency (FE) rating. This measure is based on the CSA-P.4 test method, and tests using this standard for measuring annual fireplace efficiency have shown that some units operate in the 30 per cent range, while others can range up to 70 per cent. The standard assesses all gas fireplaces, whether they are decorative units or are used for space heating. Expressed as a percentage, the higher the rating, the more efficient the unit is, and every make and model has an EnerGuide rating, not just the most efficient ones.

Modern, contemporary looks charge ahead

The style of the modern home has changed, and with it so too has the style of the appliances, which includes fireplaces and gas inserts. “While there will always be a demand for classic ceramic log set units, there are more homes being renovated and built with modern and minimalist design,” says Rachel Romaniuk of Regency Fireplace Products. “We see an increasing demand in contemporary fireplaces to compliment this style.” She says that options and accessories such as sleek faceplates, reflective panels, accent lights and glass crystal colours attract consumers because they help accentuate the flames.

Making use of the heat While purely decorative fireplaces and inserts will not generate a lot of heat, many of the fireplace models available in the market can be used to provide supplemental heat to a home, and with thermostats, flame controls and remote options, many should be considered to be part of the building’s heating system. Redmond Hearth’s Jeff Clare advises that the BTUH input and efficiency of the fireplace or insert should be calculated and added to the home’s heating requirement calculation, much the same way that the boiler or furnace inputs and efficiencies would be added in a heat loss calculation. “Zone heating is an excellent benefit of new fireplaces, since they deliver both convective and radiant heat technology to the usable living space,” says Regency’s Rachel Romaniuk. “The heat output is controllable with a programmable thermostat and remote options.” “Some manufacturers even offer supplementary heat kits that allow you to run a vent to another room for supplemental heating,” adds Clare.

“While the traditional hearth will be a mainstay for many homes, modern fireplaces with crisp lines and glass frames will continue to rise in popularity,” says David Coulson of Napoleon Fireplaces. “People have been shifting from traditional mantels and the louvered look to flush clean face styling,” adds Romaniuk.

Taking it

outside

David Coulson of Napoleon Fireplaces is expecting 2014 to be a big year for the outdoor fireplace market, as the trend to create and customize backyard living spaces continues. A quick look at any of the outdoor decks, pools and patios featured on television design shows will confirm that fire elements are becoming common additions in the backyardscape. And the fire element is not being limited to open flames. “Interior designers are using fireplaces in every room, outdoors, and now they are available for exterior walls in see-through units,” reports Redmond Hearth’s Jeff Clare. This provides an indoor/outdoor fireplace effect from a single unit.

Almost primary/secondary piping

Jeff House is an experienced industry professional and hydronics trainer. He handles the sales territory from the Niagara region to the Greater Toronto Area for Jess-Don Dunford, a manufacturers’ rep in Ontario. He can be reached at jhouse@jessdondunford.com.

You are called into a new home hydronic installation to try and solve some issues. The boiler is a modulating mid-efficient 175,000 BTUH input unit with a built-in buffer tank and a plate heat exchanger for DHW. It works with a built-in circulator designed to run as a primary loop while the heating zones are installed as secondary piping with their own circulators. There are five equally spaced pipes across the top of the loop, 8” apart, and a single return on the bottom of the primary loop. The main air handler is 100,000 BTUH; the master bed/en suite is 15,000 BTUH; and the basement in-floor zone is 20,400 BTUH. The pumps and thermostats are connected to a threezone pump relay. The boiler maintains a set point temperature in the buffer tank, and a three-way diverting valve allows for almost instant DHW priority. 1) With a total flow rate of 16 gpm, the primary loop should be: A) 1-1/4” B) 1-1/2” C) 1” D) Whatever the fitting size is on the boiler.

4) The master bed/bath has intermittent comfort levels. What is wrong with the piping arrangements?

2) The air handler is sized at 100,000 BTUH and has 3/4” fittings on it. What size should the supply and return lines be? A) 3/4” as installed. B) 3/4” if the delta T is 20°F. C) 1” if the delta T is 20°F. D) 3/4” if the delta T is about 33°F. E) C & D

3) The boiler works off an internal aquastat set for 20°F differential. With the primary/secondary piping installed as shown, what is a likely scenario? A) The owner has no complaints about being cold, so the piping must be correct. B) It’s not a true primary/secondary arrangement as the supply and return Ts are not close enough, and they are not in pairs. C) The spacing between Ts should be closer. D) Since the secondary zones are pumped and they have check valves, chances are this is fine.

A) It is fine. I have seen it this way before. B) The circulator is trying to push the water, rather than pull it, through the mixing valve. C) The primary loop is interrupted on a domestic call, so there is no hot water available for minimal periods unless there is a large domestic draw. D) You always pull the water through a mixing valve. You need to change the piping!

HYDRONICS By Ca r ol F e y

THE GREAT BOILER DEBATE

here’s nothing like modern boilers for industry controversy. People toss around the phrases and sound like experts: condensing versus non-condensing; cast iron versus copper, aluminum, or stainless steel; high mass versus low mass; cast iron versus low mass, traditional non-condensing cast iron versus modulating condensing, high efficiency versus standard efficiency.

Making condensation

People in the hydronics business can be passionate defending their beliefs. And they’re probably right based on their experience, but what they “know” may no longer be true. Or it may be based on isolated experiences. What’s true for some boilers in a category may not be true for all. That’s especially likely if the categories are not clear. The rational part of the conversation is mostly about getting the most for you and your end users’ money, and knowledge about how these systems work can help guide a contractor to the most cost effective choice. Let’s face it, condensing boilers can offer higher efficiency, but they cost more than cast iron. But is the decision-making process really that simple? Let’s have a look and see…

Condensing means that flue gases are cooled inside the boiler instead of going up the chimney. When any gas is cooled (condensed) it gives off heat and becomes a liquid. Here’s the efficiency part: The heat that results when gas becomes a liquid is transferred to the boiler water instead of heading out the flue. But this condensation and resulting additional heat does not happen without something to cool those gases while they’re still inside the boiler. It almost seems humorous — how are you going to have cooling inside a (hot) boiler? The coolant inside a boiler is the return water. Low temperature return water is required to condense the flue gases inside the heat exchanger.

What’s special about a condensing boiler? A condensing boiler can be more efficient than a conventional boiler. In a correctly designed system, it can be 90 to 98 per cent efficient. The catch is that the efficiency does not happen in all applications. To reach those high efficiency levels, the boiler must condense flue gases inside the heat exchanger, and that takes a special circumstance — coolness. But here’s the catch, and the reason that many allegedly condensing boilers do not condense (or operate at high efficiency). Condensation inside the boiler begins when flue gases drop below about 55°C. For top efficiency, the return water temperature needs to be about 17°C or less — not 71! Flue gases tend to be about 4°C warmer than the return water. This is going to require very cool return water. continues on page 116 114

Hydronics What’s special cont’d

It all comes down to the system

Here is where old industry standards go head-to-head with the new technical requirements and create a problem. From decades-old heating practices we have inherited supply water temperature requirements of something around 71°C for cast iron radiators, 82°C for copper fin tube, and 88°C for fan coils. We also have an industry standard that says that we should aim for an 11°C temperature drop (∆T) from the supply water to the return.

The words and phrases that the hydronics industry banters around don’t always mean what we think. The benefits of high mass aren’t limited to cast iron boilers. High mass can also apply to the amount of water, so condensing boilers can be high mass.

So if we use 82°C supply water, and we have an 11°C ∆T, that gives us 71°C return water. Remember, full condensing efficiency happens at 17°C, not 71°C. The flue gases leaving the heat exchanger will be about 75. The flue gases will not condense inside the boiler, and the expected efficiency will not occur.

So should you consider a non-condensing cast iron boiler when replacing that old boiler? Possibly, if you can’t get that return water cool below 49°C.

For a condensing boiler to be high efficiency there must be very-low temp return water. That means either the supply temp must be low to start with (outdoor reset can help with that), or there must be enough load(s) to reduce the water temperature low enough.

On the other hand, just because a boiler is called condensing, that doesn’t mean that it’s high efficiency, or at least not all the time. It has to have low return water temperatures in order to condense. And that depends entirely upon the system.

Then again, are you stuck with current return water temps? Absolutely not. There’s outdoor reset, doing a load calculation, adding more emitters. The bottom line is there’s a lot more to boiler efficiency and cost than just the boiler itself. Start thinking.

Getting lower return water temperatures Clearly the only way to get expected efficiencies from a condensing boiler is to deliver lower return water temperatures than are used for conventional boilers. Here are some ways to have lower return water temperatures:

• Lower the supply temperature. Of course it would not be wise to simply lower water temperatures. Do a load calculation, also known as a heatloss calculation. It will likely show that a lower water temperature than expected will meet the heating needs of the building. After all, buildings are much better insulated and more tightly constructed than they were in the days when those temperature guidelines were developed. Load calc software is easy to use, and is available — often at no charge — from equipment manufacturers.

• Use an outdoor reset control. Legislation says it comes with every new boiler, but it’s up to you to enable it. Outdoor temperatures are usually above design temperatures (the coldest expected temp, not the coldest anyone ever heard of) so outdoor reset can reduce boiler water temperatures without compromising comfort. Outdoor reset can enable condensing and energy savings that otherwise wouldn’t happen. For example, if the outdoor temperature is 5°C and the boiler provides 52°C water, with an 11°C ∆T, the return water would be 41°C. Add 4°C and the flue gas would be 45°C. It’s condensing! That would take the boiler from 89 per cent to somewhere in the 92 to 94 per cent efficiency range, because of the outdoor reset. • Add more load to the loop. Any load you can add to take heat out of return water before it gets to the boiler helps improve condensation and efficiency. • Look for low temp applications. Ideal applications for condensing boilers are those with low return water temperatures. With the lower design temperatures of in-floor radiant and snow melt, these are perfect targets.

Low mass versus high mass The debate about the boiler mass is usually associated with standard efficiency cast iron (high mass metal) versus condensing (lower mass, and made of metals such as copper, aluminum, or stainless steel). The debate is commonly framed around the amount of metal that high mass (cast iron) boilers have, but that’s not the whole story. Mass can come from something other than metal. The primary advantage of high mass is that it holds more standby heat. That means that the burner needs to cycle less frequently to reheat the boiler water. The advantage of low mass is less weight, space and cost. Because of the corrosiveness of condensate from condensing boilers, cast iron is not a common choice of metal for boiler manufacturers, so the assumption has often been that a condensing boiler cannot have the advantages of a high mass boiler. But wait a minute. Water also counts as mass. So yes a non-cast condensing boiler can be high mass if it contains a lot of water. Keep in mind that water content of the same heat output rating boiler can vary ten-fold. And more water means more heat storage. So a condensing boiler can be high mass, with high mass advantages, if it contains a lot of water.

Facing a crash of my own B

eing an HVAC tech I never worry about losing heat in my home. The system I have is old and tired but I service it regularly, change my furnace filters and keep a few spare parts around the house for those just-in-case calls.

I run off an oil furnace and hot water tank so I always have a few spare nozzles and an igniter in the garage. These are all the parts I need to get me through 90 per cent of all the issues that I could run into in the instance where my system should ever go down. Last February, however, I had the opportunity to experience a complete loss of both my heat and hot water at my home. I was home when the system crashed. That morning the power venter started to groan and rumble, and when it made a high-pitched squealing noise I knew it was only a matter of time. Within the next six hours it was completely seized. The HVAC tech in me wanted to make the phone call to a supplier who would carry the part that I needed but, I’ve never had to worry about something like this in the 10 years that I have been working the HVAC trade, so I wanted to get a firsthand feeling of what our customers, the homeowners, go through when they lose heat and hot water in their home. I’ve been on the other end of numerous phone calls from contractors who truly empathize with their customers and want to do everything possible to get their heat turned back on. I’ve rushed in parts overnight from every corner of the United States and sent said parts all over Canada. Although, up until this point, I had never had to deal with a no heat call of my own, I always understood the importance of getting a customer’s heat back on. Even from way back when I was starting out in the trade, when I was sweeping floors at another wholesaler, I know that everyone’s mood becomes a bit tense and concerned when dealing with these situations. No one is ever happy when their heat goes off, and rightfully so.

The stakeout

I called a mechanical contractor that I have never dealt with before and made sure not to give away any details of where I worked or any connections I had to the industry. I only made one phone call and the contractor told me he would come and have a look at my system within 24 hours to diagnose the problem. True to his word he was at my home the next day. I live in a small cottage type home in a forested area of King Township north of Toronto, and as I mentioned, I heat with an oil-fired Brock Furnace, and my hot water is an oil-fired Aero hot water tank. These are both common vented through a side-wall power venter. I didn’t want to be the one to deal with

What’s needed is a certain amount of finesse and an all-handson-deck attitude to get through as quickly and efficiently as possible, and you are always very anxious when that homeowner calls for an update because unless the answer is that the part is here and in my hand, the phone call never goes well. Now it was going to be my turn to be that homeowner on the other end of the phone.

the contractor, so I asked my girlfriend to spearhead all of the personal conversations and phone calls. I didn’t want to play dumb, but I also didn’t want to tip my hand about my experience and end up telling the contractor what was wrong, so I tried to stay out of all of the diagnostics, explanations and ordering. The contractor was good and was able to diagnose the problem with the power venter in about 30 minutes or an hour. He told my

girlfriend that he needed to make some phone calls and see where the part was in stock and how long it would take to get. I had made these phone calls earlier myself and found an aftermarket power venter in stock in the general region, but as I mentioned, I really wanted to get a complete feel for how a typical homeowner may experience this type of situation, so I didn’t do anything and let this state of affairs play its course. continues on page 120

Lesson learned I learned a few things from this adventure. I think the biggest lesson is the importance of having a finger on the pulse of the complete supply chain available throughout a region. With a few phone calls – especially to veterans of the industry – you can source almost anything locally, and generally someone will have it in stock.

Waiting on the fix

The contractor got back to us in a day and told us the part had to come from Quebec and it would be about a week delivery. After calmly explaining to my lady that we would be without heat or hot water for a week, and why I was insistent that we experience this first-hand, we set about putting up space heaters around the home and calling friends and neighbours asking if we could arrange for us to use their showers, and maybe plan for a few slumber parties. Most of my friends were very interested in why I wanted to go down this road, especially when they knew where I worked and what I did. I had helped out a number of these friends personally in their times of no heat calls in their own homes. I told them that I have always had an inside track on topics like this and, as such, have never really felt what it was like to be without for any extended period of time. For those with a link to ‘90s music, you might understand that I could almost envision my theme song being Pulp’s Common People. And I was fine with that, even if I did run the risk of appearing a bit egoistical in front of a few friends. I will confess though, it was a very humbling experience for me. When we were home the thermostat never got any higher than 50 degrees Fahrenheit during the eight days that the furnace was down. We washed dishes by boiling the kettle and mixing it with cold water from the sink. We spent most of the time on the couch under blankets sitting right beside the small space heaters drinking tea and coffee. The bedroom was almost uninhabitable but, in keeping with the spirit of this experiment of mine, I decided to try a few times to sleep there. Even with multiple blankets falling asleep was nearly impossible. I never phoned the contractor and he never called me. I just waited out the week and on day seven we got the call that the part was in and he could come the next day to install. Twenty-four hours later, our home was at 70 degrees and our hot water was back at the tap as opposed to the kettle spout. 120

Wholesalers understand the urgency of these situations and want to help you in any way they can, even if it’s a recommendation to call their competitor because they know of another shop that keeps a certain item on its shelf. It may not be the price you were expecting or the exact bolt pattern but if it is something that will work, then it may be worth getting the local item to get the heat back on. I don’t need to tell you that your customers are cold and uncomfortable, but there are resources available to help you help them.

A message TO GIVE the homeowner No one wants to see a homeowner or customer without heat. No one is holding the part that is needed in their hand and not doing everything in their power to get it to the contractor. Although your customers may not always believe it, especially since beliefs start to wane as the days of sitting in the cold add up, but someone somewhere is trying very hard to get them back up and running because we all know what it is like to have no heat, and it is not fun.

Funding Facts According to Alberta Infrastructure, the new Royal Alberta Museum is expected to cost $340.5 million, with $122.5 million of the funding coming from the federal Building Canada Fund program. The building’s construction is expected to be complete in 2016, with work to acclimatize the building and install exhibits and collections complete for the grand opening of the museum in late 2017.

Protecting a province’s

history The building of the Royal Alberta Museum

ince 1967, the Royal Alberta Museum (RAM) has served up a countless number of artifacts, galleries, and educational programs, showcasing the province’s history to art and history enthusiasts and schoolchildren. On April 6, 2011, an announcement was made to build the new RAM in the arts district of downtown Edmonton. The new facility will have 39,000 m² of exhibition space, approximately double the space of the current museum, and feature state-of-theart laboratories, workrooms and storage vaults, as well as improved public amenities. The design-build project is being constructed by Ledcor Design Build (Alberta) Inc., a consortium consisting of Ledcor Construction, Dialog Design and Lundholm Associates Architects. The project is being constructed at the former site of Edmonton’s Canada Post office in downtown Edmonton, which is currently in the process of being demolished. According to Mike Roper, senior project manager for Ledcor, the end of the demolition and the start of the foundation pour is expected to happen this month.

N+1 redundancy is a form of resilience that ensures system availability in the event of component failure. Components (N) have at least one independent backup component (+1). 122

Fire and Water

protection Keeping water away from the collections is always a top priority, so museum planners don’t allow water or heating systems to run above collections spaces. This forces architects to do some planning in advance with regards to where to place mixing boxes, supply piping and various other types of mechanical equipment. “The majority of the mechanical spaces will be fed from basement levels,” says Tim McGinn, principal at Dialog Design. “All air systems will provide cooling and heating from remote TURs. Storm drains, when unavoidable, have drip troughs monitored with moisture sensors. Only seamless sprinkler piping is routed over collections, with recessed heads or cage protected heads. Wet services for labs and workrooms are routed in casework service chases from vertical chases, reducing risk from lateral services. Each collection area is separately fed through a readily accessible and monitored isolation valve to allow shutting off water quickly and draining the lines once a risk is assessed and contained.”

Main system

The main system for the museum will be a hybrid condensing and non-condensing boiler plant supplemented with a hybrid central heat recovery modular chiller and conventional centrifugal chiller plan with cooling towers, with all systems complete with N+1 redundancy of critical systems, according to Tim McGinn, principal at Dialog Design. “Air system redundancy will be provided for galleries, labs and collections, the bug room and the fluid specimens lab in the form of dual components within the air handlers, with each stream sized for 50 per cent redundancy. Non-critical spaces will consist of traditional ventilation systems with no redundancy. Chemical and particle testing, both within the existing museum and Edmonton’s outdoor air, has identified the specification for HVAC filtration equipment. Filter housings are being provided for future flexibility to accommodate possible advances in gas phase filtration technology as the occupancy date approaches, three or four years from now. The air handlers supply a preconditioned mixture of outdoor air and recirculated air to the terminal units located in the terminal

In the

Zone

The museum will have seven different environmental settings in which the relative humidity and temperature set points and permissible ranges are different. There will be separate air systems serving the lobby, theatre and kitchen; offices, feature gallery, collection galleries, lab and collection storage areas, children’s museum, and bug discovery area. “Systems serving the unique environmental zones [collection areas] have terminal unit control on volume, temperature and humidity,” explains McGinn. “Dew point control on each unit maintains minimum humidity to satisfy the dominant zone of the system, reheat recovered from the cooling plant is used to fine tune space temperatures for each zone.” No zone will be permitted to get too big because of concerns of how one would deal with an insect infestation or the spread of smoke, says Lundholm.

unit rooms (TURs) – rooms that allow airside terminal unit control to be provided close to where they are needed without flood risk from wet services jeopardizing the collection storage or exhibit areas. Each TUR will contain terminal unit assemblies that serve a single zone, and each terminal unit assembly will include a pressure independent terminal damper and controller, a reheat coil, and a steam humidifier. Relative humidity will be precisely controlled by the zone specific humidifiers. Coupled with central dehumidification and zone reheat, humidification levels will be very accurately maintained, to ensure the collections are not damaged. McGinn said the approach to locating TURs remote from the fan rooms and closer to the artifact exhibit or storage spaces provides a number of advantages to the alternative of placing all systems terminal units back in the remote fan rooms. Those advantages include a shortened distance between the reheat coil/humidifier and the space served, which will allow for quicker control response times and more accurate control; modifications in the future due to program or load changes will be easier to incorporate at the zone level and more cost effective with less disruption to the facility since sheet metal ductwork between the terminal units and the spaces will be shorter and more easily modified; the single main supply duct from each air handling unit to the TURs can be sized for future considerations and optimized for velocity and lower pressure drop; and duct heat loss in heating and cooling modes will be reduced due to optimized main supply duct size and/or velocity and shorter runs from the reheat coil to the space served. Outdoor air quantities are controlled to maintain building pressurization and space CO². Exhaust air from the system is cooled during heating season and recovered for heating purposes with the central heat pump system.

Managing risk factors ASHRAE’s chapter 21 on museums and archives deals with the relative humidity temperate and air purity issues. In the case of the Royal Alberta Museum, ASHRAE Class A was selected as the standard for most of the collection spaces. Class A is a general standard that permits some seasonal variation, and slow variation in relative humidity, says Lundholm Associates Architects’ Michael Lundholm. “We do have some areas that have to adhere to a higher standard, Class AA, and that means you have to be able to hold a specific RH [relative humidity] anytime of the year, plus or minus a very tight tolerance,” said Lundholm. “For example, when the Dead Sea Scrolls came from Israel to the Royal Ontario Museum they demanded very tight standards. The museum doesn’t want to be in a position to not be able to accept some of the fabulous exhibitions that are available.”

Marketing with Doug MacMillan

Your questions answered – Part 2

uch like a doctor or accountant talking shop at a party, once someone knows what industry you are in, you can bet your bottom dollar that they will want to pick your brain for a bit of advice. As such, last issue (January/February 2014) I started a list of some of the most common or most intriguing questions that I’ve been asked about marketing over the past little while. It was a fun exercise, so let’s continue the dialogue with a few more insights that might help as you examine and plan your marketing activities for the coming year.

Why didn’t anyone come to our press conference?

Are the Yellow Pages dead? Well, they’re gasping for air. When’s the last time you opened one of those dusty books? The printed canary pages are pretty much in the grave, in my opinion. However, Yellow Pages advertisers can get their ads online too, and Yellow Pages has managed to achieve pretty decent search engine optimization. In other words, if you’re in there and people Google for your services, there is a pretty good chance they’ll find you. Of course, there are many other methods of search engine optimization that are just as effective.

M e c h a n i c a l

Traditional press conferences aren’t really in vogue anymore unless you’re Rob Ford, Apple or can promise editors a truly newsworthy event. (And you don’t want to over-promise and under-deliver.) Media outlets are understaffed compared with 20 years ago, and assigning a reporter to a press conference can mean a half-day commitment. Moreover, they can get the story and the photo opp in countless other ways – email, social media, blogs, etc. To get the “ink” do more of the legwork yourself. Write a strong, professional news release that delivers timely value for the reader or audience. And remember to stage, shoot and send a few good photos that match the style used in the publication.

Is social media really that important to business? It’s not like my kid and her friends own a house. Using social media just because it’s out there is foolhardy, I agree. However, making broad assumptions may be a greater marketing sin. These days, it’s media that is a lot more than social. Many professionals – including yours truly – rely on Twitter, Facebook and other channels for news, weather, sports, collaboration, research, and more. According to Fast Company magazine, the fastest growing user group on Twitter is aged 55 to 64; and the 45 to 54 age bracket is the fastest growing user group on both Facebook and Google+. It takes some strategic thinking, research and commitment to build and execute a social media strategy. However, done well it can build a contractor’s brand, strengthen relationships with customers, effectively communicate important or timely news, identify and pursue top recruits, and much more.

What materials – brochures, tablets with PDFs, pre-written sales contracts, etc. – do my technicians need to increase our upselling?

I have a lot to say in my ad. Why do I need white space? I could use that empty area to put more words. Open a newspaper, Yellow Pages book or web search engine. I bet it’s a big cluttered mess. In fact, it can be tough to know where to look. Now imagine an ad, even a small one, on that noisy landscape. It’s mostly white (or solid black, since reverse ads work nicely, too) with a few words in the centre, and maybe a logo on the bottom. Imagine where people are inclined to look. Ads are designed to draw attention, not to sell. That’s your job.

The tools can come in any shape and size, and should reflect the customer and seller, as well as your brand. For example, you don’t want to claim that you’re environmentally responsible and then fan out a bunch of glossy brochures when you can review them on an iPad. However, tools are secondary. Based on my experience with contractors, if you want your techs to sell, they should be armed with training. Identifying opportunities and convincing customers they need them is a wholly different skillset than replacing a burner or installing a water heater. Too often, we ask people to step out of their comfort zones without giving them those tools – the right questions to ask, the signs to watch for, overcoming standard objections, etc. A great tech can be a great sales rep with enough skill and confidence.

Which marketing gurus do you read or follow? Great question! There are so many experts out there, and social media is a terrific way to pay attention to what they have to say. But, it can be overwhelming and eat up countless valuable hours. Of those I follow, here are the three I watch most closely: Seth Godin - @thisissethsblog - sethgodin.typepad.com Seth’s daily blog is usually a two-minute read, and it’s his common sense approach to business and marketing that keeps me coming back. Sally Hogshead - @sallyhogshead - howtofascinate.com Sally’s book, Fascinate, is an exceptional primer on how to build a brand by understanding and pursuing seven triggers of fascination. It’s a must-read for sure. Paul Alofs - @alofs - thepmcf.ca Paul Alofs is a member of Canada’s marketing hall of fame and the current CEO of the Princess Margaret Hospital Foundation. He’s done some tremendous things. He calls himself a “Passion Capitalist” and has some amazing insights in how to build and harness passion in your people. Way cool.

Saving with sublimation

Sublimation

he new age of refrigeration is moving away from conventional methods of operation as we continue to seek an energy efficient future. Having a look at medium- and low-temperature applications, we can find significant energy cost savings by using the frost to help maintain space temperature, by managing the sublimation rate of the frost. We all know that frosting of the evaporator is inevitable, and it is also the most common cause of inefficiency in evaporators. Instead of the typical mechanical controls, intelligent controllers that can be retrofitted to any system can effectively manage the refrigeration process and eliminate the need for a multitude of defrost cycles per day by harnessing the latent energy already in the evaporator. They will manage the system to manage the efficiency. Similar to conventional controls, intelligent controllers operate the refrigeration cycle until the setpoint is met. When the room temperature is met, the controller closes the liquid line solenoid valve and turns off the fans. The condensing unit continues to operate until residual refrigerant is boiled off. The graph below shows how, as the refrigerant is pumped out of the evaporator the temperature of the coil is reduced as the fans are de-energised to avoid over-cooling. This residual refrigeration acts as a flywheel, and brings the coil temperature further below the space temperature. At this point the condensing unit and evaporator fans remain off until such a time that the room thermistor/sensor rises a fraction of a degree. The fans will then come on, leaving the condensing unit off, and sublimate the coil frost until the room reaches its setpoint again. This provides tight temperature control and widens the gap between compressor on/off cycles. This also dramatically reduces the need for electric/hot gas assisted defrosting. This process is repeated until the coilâ&#x20AC;&#x2122;s latent energy has run out, at which point the process begins all over again.

For those who may not be versed on this method, the short explanation is taking a solid (such as frost on the evaporator) and transitioning into a vapour, without passing through a liquid state. A refrigeration effect of over 1,200 BTU per pound of frost is available through this process.

Kevin Gill (left) and Ed Carriel, of Frigo Technologies, in a cold storage facility in Toronto.

Spotting opportunities for sublimation When using a conventional low-temp system, you would most commonly have a defrost clock that activates several defrost cycles per day using electric elements or hot gas. These cycles run for a set period of time emitting heat to the face of the evaporator coil, and melting any frost. This not only adds to load values, but it drives up energy consumption as it defrosts and then re-cools the space, adding to the customerâ&#x20AC;&#x2122;s operational costs. This is also a wasted opportunity to better utilize the frost.

Look for grants For larger applications, power authorityrecognized energy monitors can be used to measure energy consumption. Some provinces may even offer grants, rebates and other incentives for systems making use of this technology.

urtis Clow has always been a hands-on type of guy.

Even at a young age, when he was unsure what career path he wanted to pursue, he always knew it was going to involve being on the tools. “Right out of high school I was interested in the electrical field but I didn’t really know what I wanted to do,” he told us when we tracked him down in southwestern Ontario. “I just knew I wanted to do something with my hands.” Curtis decided to start his career in the mechanical trades by going to college and picking up his gasfitter ticket through the heating and cooling course at Fanshawe College, and doing a sheet metal apprenticeship split between Mohawk College and Fanshawe College. That path has led him to his current position at W.J. Barnes – a provider of heating and cooling products, installations and services for residents in Sarnia and the surrounding area – but he could see a time when he moves up, and off the tools, possible working his way into management. But that’s in the future for the 27-year-old technician. M e c h a n i c a l

DID YOU KNOW? • Curtis is into cars and bikes, and enjoys puttering away on them in his spare time. • When he retires, he would like to travel the world. • Curtis would like to get into real estate, acquiring houses and renting them out.

Seeking

savings with VFDs One of the challenges experienced with some refrigeration and air-conditioning systems is maintaining stable operating conditions. As system pressures fluctuate, the various refrigerant regulators and other components are in a constant state of â&#x20AC;&#x153;trying to catch up.â&#x20AC;? For many years, the displacement of compressors was adapted to the load by varying the displacement directly. Note that these methods (i.e. cylinder unloading, etc.) are generally engaged while the motor turns at its full speed on 60 Hz supply mains. These unloading methods are very effective at reducing the capacity when needed, but as the load varies better control will be realized with smaller capacity steps.

ith energy costs on the rise, equipment owners are looking for ways to reduce their plant energy consumption. Modern control systems have enabled much better control of system parameters. Referring back to the displacement of the compressor, consider what happens to pressures as a compressor is loaded or unloaded.

Pulse Width Modulation

The capacity of the compressor will change in close proportion to the size of the capacity step. Even PID controls are not able to help reduce the step size, although they will work to smooth out rapid pressure changes by controlling valves accordingly. The operation of a compressor with a variable frequency drive or VFD seems to be a new area of interest for many contractors, engineers and equipment owners. With a VFD, the capacity of the compressor may be varied infinitely between the minimum and maximum speeds. This infinite control generally results in a very stable suction pressure. Stable suction pressures offer the advantage of better control of process temperature. This, in turn, can also result in better quality of refrigerated products.

200

Working with hot gas bypass Hot gas bypass is a system-level capacity control method that has proven to be very effective over the years. In addition to ensuring a lower limit for the evaporating pressure, oil return tends to be better when the hot gas is fed into the evaporator, along with the liquid from the expansion valve.

When considering using a VFD with a compressor, it is advisable to ensure that this is acceptable by the compressor manufacturer. Additionally, it is important to respect the refrigerant-specific operating limits that were established for the compressor.

Perhaps the largest disadvantage of this hot gas technique is the fact that the minimum energy input to the compressor is established, in part, by the minimum suction pressure that the hot gas bypass works to achieve.

Keep in mind that a VFD probably represents the highest first-cost compared to other capacity control techniques, and the VFD tends to reduce efficiency when the compressor is operated at its rated speed at 60Hz. This is primarily due to the losses that take place within the drive circuitry. This is why a VFD may not be a good option for systems that tend operate fully loaded most of the time.

In some systems, medium- or even high-temperature refrigeration and air conditioning may come at a cost in kW/ton that is similar to low-temperature refrigeration.

Above the limits WATCH FOR SIGNS In addition to varying the speed infinitely within a predefined speed range, some compressors may be able to operate trans-synchronously. This means that the compressor can operate above the line frequency of 60 Hz. In order to do this, however, it is important that the compressor is not already operating at its maximum input power at 60 Hz. Generally, it is good practice to select the VFD-compressor combination such that the motor will not exceed 90 per cent of its maximum power rating at maximum speed. Operating a compressor trans-synchronously enables a smaller compressor to be used for the application, which helps reduce the first cost.

Foam watch When displacement is engaged or disengaged, the system pressures fluctuate. This can induce foaming of the compressor oil and in extreme cases, may even result in liquid slugs moving towards the compressor.

Design considerations A common question that is regularly asked is how VFD use affects pipe sizing along with the sizing of the various system components in general. From a pipe and component sizing perspective, the same considerations regarding mass flows and velocities apply to all capacity control methods.

Getting up to speed When a compressor starts up, a large inrush of current to the windings takes place. In larger installations, soft-starters are often used to limit the start-up current. VFDs also provide a soft-starting characteristic as an additional benefit. Both softstarters and VFDs must be adjusted so as to ensure that the compressor reaches its minimum allowable speed within a timing specified by the compressor manufacturer. This timing is usually within two to three seconds. Since the VFD is a programmable device, it is possible to program maximum limits for current and/or power consumption. With these limits established within the drive itself, the maximum motor speed will be limited so that these values are not exceeded. So in this respect, the VFD also helps prevent motor overload.

Vibration avoidance

At lower mass flow rates, the velocity in the pipes will decrease. The system designer must size and select components, and then layout the piping and components, in such a way so as to ensure adequate oil return at all times.

Picking the right drive With proper application of a VFD, there are many benefits that can be promoted to equipment owners. However, it is extremely important to ensure proper drive selection. Drives for positive displacement compressors are usually applied with a constant torque algorithm. In order to achieve this, the voltage to frequency ratio remains constant throughout the speed range. The drive may also have to be able to produce a somewhat higher torque during start-up to account for the various “torque spikes” that occur with every 360-degree revolution of the motor shaft. This is more important with reciprocating compressors than with scrolls and screws. For example, the crankshaft of a two-cylinder compressor only has to push two pistons upward for every revolution. In a six-cylinder compressor, however, operation tends to be somewhat smoother from the drive’s perspective due to the larger number of cylinders.

Since the VFD can take a compressor through a relatively large speed range, it becomes more likely that the resonant frequency is reached for a particular installation. Fortunately, most drives offer the ability to skip this frequency, or a small range of frequencies, in order to prevent resonance elsewhere in the system. It is important to test the compressor at various loads and speeds during commissioning to ensure that resonant frequencies are avoided, and that the compressor always operates within its safe operating limits. 202

A PRIMER ON PIPING

Let my BTUs

FLOW!

Most installers have become aware of and embraced primary/secondary (P/S) piping concepts. The concept is simply to allow the hydraulics of separate pumped circuits to live in harmony. The pipe size, and the proximity of the closely space tees, are what ensure proper flow. Primary/secondary allows multiple, sometimes differently sized, circulators to work together in a common piping circuit, without flow issues.

f I were to choose one concept (and related products) that has changed the way we pipe boilers, the hydraulic separator would be the standout choice. The hydraulic separator is an evolution of P/S piping and flow control. The separator, commonly referred to as a hydro separator or low loss header, is basically P/S in a box, or tube, if you will. The separator provides the closely spaced tees and the wide open passageway for multiple flows. In its simplest form, a separator has a centre tube dimension that is three times the size of the ports connected to the centre tube. If, for example, your design calculations require a 1” pipe size, the barrel of the separator would be 3”. The hydraulic separator is especially useful for piping boilers with high pressure drop style heat exchangers. The use of a separator ensures that different sized pumps and flow rates can exist, or separate, within the common piping. The boiler’s heat exchanger may require a high head circulator to provide adequate flow, while the distribution side is pumped with a smaller low head circulator. With a separator, the high head boiler side circulator will not cause or induce flow in the secondary circuits when that pump is off, and vice versa. On either side of the separator, multiple pumps, boilers, inputs and outputs can be combined. Different types of boilers could be integrated and piped to a separator. Even different types of heat generators, or heat emitters could be combined on either side of the separator. Heat pumps, biomass boilers, even solar thermal can be combined and successfully piped via a hydraulic separator. Separators come in a variety of sizes and shapes. Some Some installers build their own brands are fabricated from square or rectangular steel separators. Contractors that own a T-drill tube.

More than just

hydraulics

Recent sightings at the AHR Expo in New York indicate that many mod-con boiler manufacturers are offering tube and shell type heater exchangers. This type of heat exchanger produces far less pressure drop, and as such some boiler manufacturers are maintaining that a separator is not needed or is of limited value on a low pressure drop type of boiler heat exchanger.

Bigger can be better

It can be beneficial to think of the separator as the wide spot in the piping or fluid path. You cannot oversize the separator. In fact, some installers and designers prefer to use a tank as a hydro separator. This gives the system some additional thermal mass and provides many of the same features as a separator. A well-insulated tank with a wide assortment of connection ports is ideal.

Separators have evolved, however, as the installers have become more familiar with their workings and value to the system. Many top quality hydraulic separators now perform multiple important functions for a system. Consider that all hydronic piping systems need a good means to deal with air removal. Most of the savvy installers and designers have embraced air removal products that efficiently remove large and micro air bubbles. Well-engineered air removal devices will also handle dissolved or entrained air. Even systems that are over pumped and experiencing flow velocities in excess of the industry accepted four feet per second will be well served by high efficiency air removal products. But there are even more benefits of a well-engineered separator. Dirt and sediment removal can be another concern. Dirt and debris can be a concern when retrofitting systems piped with steel, or with cast iron radiators. It’s become imperative to keep these contaminants out of boiler heat exchangers, all the control valves, and any regulator valves, like TRVs, zone valves, balancing valves, etc. Look for hydraulic separators that can trap very fine iron ferrite with a magnetic band attached. Iron ferrite can be found, for example, in systems with nonbarrier radiant tube. These powdery fine particles can be near impossible to trap with a strainer or cartridge type device. A powerful magnet does an incredible job of catching the fines that can be inside tight systems.

One nice feature found on some brands of hydraulic separators is a pre-formed insulation jacket. This helps cut down on heat loss from the separator and may put a smile on the face of the insulation contractor.

A sense of control A separator can also serve a purpose on the controls side of a system. A sensor, properly located in the separator, can become the control reference point for the boiler operation. Now the boiler sees the piping and the separator as its load. This can help eliminate short cycling and also offer accurate temperature regulation of the boiler loop.

High-performance HVAC

B y Go r d C o o ke Gord Cooke is a professional engineer who has spent 20 years helping builders and HVAC contractors implement innovative technologies into high-performance homes. He has particular expertise in IAQ and air flow management in houses, and can be contacted at gcooke@airsolutions.ca.

Sealing the

Deal

While it’s now a new home requirement in Ontario and an Energy Star for New Homes requirement across Canada, let’s all embrace duct sealing and extend the service to all joints in all systems. You and your clients will really enjoy the ability to be able to control and balance airflows and temperatures in homes.

here was a flurry of phone calls in wintery Ontario in the new housing HVAC world as contractors began to realize there was a building code requirement for duct sealing that came into effect as of January 1. The explicit wording below took many by surprise:

6.2.4.3. (12) Where a supply duct is located in a conditioned space, the ductwork shall be sealed to a Class C seal level in accordance with the SMACNA, “HVAC Duct Construction Standards – Metal and Flexible.” Class C sealing includes transverse joints only, as indicated in this image. I suspect this rather surprising addition to the Ontario code was prompted both by the success of duct sealing in the Energy Star for New Homes program across Canada and the fact that the International Energy Conservation Code 2012 in the U.S. requires duct sealing and duct leakage testing in all new homes. This should be seen as a great investment for our industry. In most homes in Canada, ducts are in conditioned (heated) space, mostly in basements, so until recently it may have been appropriate to think there wouldn’t be a lot of value gained by sealing ductwork, specifically from an energy efficiency perspective. Sealed ductwork does provide some efficiency gain, but that’s only a portion of the story.

The reasons are plentiful

This sketch shows the duct sealing requirements for Energy Star for New Homes. In the Ontario Building Code 2012, only the duct joints on the supply ducts are required to be sealed.

Central air conditioning that uses the same ducts for cooling and for heating, seasonal variance in loads in different rooms, and the much higher expectations of homeowners for even temperatures in all rooms are just a few considerations that warrant the $100 incremental cost in materials and the two to three hours of labour required to properly seal duct systems. The need for thorough sealing was hammered home to me when I explained to a shocked homeowner who was unhappy with the temperature control in their brand new, three-storey urban townhome that it was normal and expected for properly installed sheet metal ductwork to leak at a rate of 20 to 25 per cent. They looked at me quizzically and said, “They leak?” In their home, that leakage made it impossible to produce any significant change in airflow to the farthest, longest runs. continues on page 210

High-performance HVAC continued from page 208

Progressive HVAC Now, allow me to share with you a very encouraging story. A medium-sized but progressive builder in southwest Ontario, Doug Tarry Homes, was finding that the more they did to build and promote their high-performance homes, the higher the expectations of his homeowners became. Specifically, homeowners were expecting far greater consistency in room temperatures throughout the house, an expectation that, despite attempts to balance the duct system, the builder couldn’t seem to satisfy. While investigating the issue, we found that in spite of very good workmanship, the sheet metal furnace ductwork had an air leakage rate of over 25 per cent. To its credit, the builder stepped up and purchased both duct leakage measurement equipment and comprehensive airflow measurement devices about 18 months before – the only builder I know of in Canada who has done this. The company’s progressive HVAC contractor now seals all joints in the duct, uses the test equipment to verify that duct leakage rates are below six per cent, and is able to balance airflows throughout the house to exactly the design flow for each room. In February, we demonstrated these steps to the real estate agents who sell the homes as an explanation as to why it was possible to have every room in the house – from the basement to the bedroom over the garage – at exactly the same temperature even though it was -15˚C outside. The sales agents were thrilled that this particular solution to appease the ever increasing expectations of homeowners had an incremental cost of less than $100 in materials and liked the story of how it was the dedication to good workmanship by the HVAC contractor that made all the difference. This HVAC contractor has been so encouraged by the results that the company now wants to purchase their own equipment so they can offer the same service for all of their other builder clients. The contractor said to me, “It’s hard to do it wrong, when you know what’s right.”

How to get committed Get started by committing to test at least a few systems in the next few months in new and existing homes. This is done with a piece of equipment often called a DuctBlaster. A small number of energy evaluators across the country have this equipment. Forward-thinking HVAC contractors may wish to purchase this equipment as well. It requires an investment of approximately $3,000.

Pan returns must be sealed

The target in new homes should be less than 10 per cent leakage – that is, no more than 10 per cent of total system flow leaking at a test pressure of 25 Pascals (0.1” W.C.). Use duct mastic and approved tapes to seal any accessible joints. A paint-on mastic is always considered to be the best technical choice, although some will complain it is messy to use. I haven’t found that to be the case in the limited number I have done, but if you prefer to use tape, be sure to use a good quality one. All professionals will recognize that the traditional grey cloth tapes don’t provide a long-term solution. The foil backed, butyl (synthetic rubber) have performed very well for most contractors as long as you take the time to ensure the joint is clean before applying; and then apply even pressure over all the tape to ensure proper adhesion.

All sealing ducts and take-offs with mastic

There is a new family of oriented polypropylene tapes (OPP) with an acrylic adhesive that is gaining popularity. These come in different colours and may be described as looking like a thick housewrap or sheathing tape.

Did you know? Any tape you choose should bear the UL 181 or ULC-S109 Standard logo.

PLUMBING By F re d Br e t z k e

TO WET VENT T OR CIRCUIT VENT, T, THAT IS THE QUESTION

ack in 2005, a major change happened in the code. The powers that be changed wet venting. Actually, they brought back some of the old rules. Wet venting used to be easy. Whenever I was with a customer and they wanted to put a basement three-piece bathroom in, it was easy. The reason why it was easy was because you could put the bathroom fixtures in any formation. The tub could be the last fixture and it didn’t matter where you put the toilet connection. This was all according to the ’95 code.

Well, it was deemed necessary in 2005 to make it mandatory for the toilet to be the last connection, as we believed that the toilet’s fixture unit load should drain downstream of the wet vent, so it wouldn’t affect the smaller fixtures like the tub or basin, for example. Other major changes were the new rules on circuit venting. To some, all these rule changes may seem unnecessary but, actually, once you know them it gives you more options. Let’s check each form of venting out…

PROS AND CONS OF A WET VENT: PROS

1) A wet vent is easy to size, and it remains one size, full-sized, throughout. 2) Only one vent is necessary for a group of fixtures. 3) Works well for a three-piece bathroom. 4) Wet vents are also good for a multi-storey kitchen sink application.

CONS

1) The wet vent pipe is oversized right up into the vertical wall. This means if you have a bathroom with three or more fixture units discharging into it you will need at least a 3” pipe in the wall. This is not desirable for a two-by-four wall. 2) The toilet has to be the last connection, which sometimes makes it difficult to lay out. 3) No more than two toilets can be wet vented.

What is a wet vent? It’s basically an oversized pipe that is big enough to carry water and air. The use of ABS pipe in a drainage system is a perfect example for how a wet vent works. Just as the water molecules adhere to the walls of a plastic water bottle when you shake it, water or waste adheres to the inner walls of ABS pipe when it’s drained vertically, thereby leaving a centre hole of air in the middle. This centre air hole is the vent on a properly sized wet or circuit vent, when the pipe changes direction to horizontal, gravity takes over and the air space or vent is left on the top half of the pipe.

RULE CHANGES The rule changes to circuit venting that happened as of the 2005 code have made it necessary to change how venting is taught. Here at SAIT, we now teach residential circuit venting in the second-year program instead of waiting until third year, as more time is required for its learning curve. This may change again since many find residential circuit venting to be harder to grasp than commercial circuit venting, due to the layout of fixtures. In either case, once you learn all the rules of wet venting and circuit venting, it makes it very possible to be creative in your venting and to save money by using less pipe.

What is a circuit vent? A circuit vent is basically a wet vent with more rules. It was originally designed for a battery of commercial fixtures, but now we can use it residentially, as itâ&#x20AC;&#x2122;s suitable for venting four- and five-piece bathrooms, which are becoming more and more

common. Circuit venting has a lot of rules, and can be used in commercial and residential applications. As circuit venting is basically a wet vent, it does have to be sized correctly to be big enough to carry air and waste. A circuit vent is, as it sounds, a basic circuit of piping, or a circle of piping that is part drain and part vent.

flushed, the waste or liquid pushes air pressure in front of it down the pipe as it also draws air from behind it from the circuit vent located upstream of it. A relief vent is required every time, since this is where the displaced air pressure in

front of the discharged waste will go. So, the circuit is formed and as the fixtures are flushed they draw air from the upstream circuit vent and push air up the downstream relief vent.

PLUMBING continued from page 213

Pros and cons of a Circuit vent:

1) A circuit vent is not a single size throughout, which means the pipe is smaller at the upstream side and larger as it goes downstream. This means it’s possible to have a small 1-1/2” vent pipe in a two-by-four wall. 2) It’s possible, sometimes, to have only one vent for a group of fixtures. 3) Works well for a four- or five-piece bathroom with a battery of fixtures. 4) You can circuit vent more than two toilets. 5) The toilet can be connected anywhere on the circuit vent, it does not have to be the last connection.

Cons 1) The circuit vent requires as much as three tables to size from the National Plumbing Code: the 2.5.8.1. Circuit vent table; 2.5.8.1. Wet vent table; and 2.4.6.10. b Branch table.

WORDS

ADVICE My original boss back in 1977, used to say, anyone can be a plumber if you give them enough pipes.

2) There is a longer learning curve to understand the many rules of circuit venting.

The best plumber is the one who uses the least

3) Circuit venting can only be used in a single-storey application.

While the twisting effect of the Coriolis force is real, the effect is so small that it does not influence the direction of rotation of water down a toilet or sink drain. What does? The direction at which water is directed to the drain.

Cistern pumps

Tankless with storage

Franklin Electric’s C1 series submersible cistern pumps are designed for use in greywater and filtered effluent service applications, with the ability to pass solids up to 1/8” in diameter during normal operation. The pumps are constructed with a stainless steel motor and outer shell with engineered polymer hydraulics for corrosion resistance and abrasive handling.

Cutting beyond limits

Tool Tips

Creating pathways

hether you are into plumbing and running hot and cold water lines, or are dealing in HVAC and hydronics with vent runs and process lines running to and fro, the need to create a pathway for pipes and wires is an ongoing battle, and the faster and cleaner the work, the quicker you can get onto the next task on your daily to-do list. For up to a one-inch hole in wood, a sharp auger bit will typically do the trick. A standard auger bit or ship auger bit would work, and some will even cut through finishing nails. Once you get beyond the need for a 1” diameter opening, it’s time to check out a hole saw.

A rough hole will do for passing pipe and conduit. And most of these rough-cut hole saws will go in on an angle on the stud, which is handy for running drain lines. If you are working with metal studs, step bits are the most accurate and fastest method to create holes.

When using a core bit, the limit is the depth of the bit. If the thickness of the wall exceeds the depth, drill to the limit of the core, tap out the core and continue until you are through the wall.
