AquaPLEX is a remarkable new water heater tank material created by alloying 300 and 400 series stainless steels and capturing the benefits of both. Fully pickle-passivated after complete tank fabrication, AquaPLEX is naturally corrosion-proof in potable water regardless of stored water temperature. • Tank walls are solid AquaPLEX. There is no lining, coating, cladding or plating of any kind. Nothing that can erode, crack, delaminate or wear through over time and expose a steel tank to water • No anodes of any type are required.

AquaPLEX tanks are unaffected by aqueous or galvanic corrosion so an anode rod has nothing to do. And this means tank life cannot be compromised by insufficient anode rod “reachâ€? or condition • AquaPLEX is immune to chloride-induced stress corrosion cracking; a known failure mode for 304L and 316L stainless steel in hot potable water • AquaPLEX is as much a process as it is a material. Tanks and welds are designed to eliminate crevices and we employ unique fabrication processes to ensure maximum longevity of the tanks ZZZ 39, FRP

THE

EDITOR’S

DESK

Lights, camera, action!

To borrow a phrase from a well-known ringside announcer, “It’s showtime!” Welcome to the CMPX show preview edition of Mechanical Business.

I make no secret that I’m a tradeshow junkie, and the CMPX in Toronto is always a good one. Between dropping into learning forum sessions, to chatting with readers and advertisers, it’s one that I look forward to every two years.

The show is a fantastic opportunity to catch up with industry colleagues, to meet new people, and to dig into the changes that are taking place in the industry, both with respect to legislated changes and technological advances.

Being on the editorial side of the trade, I find that conversations during the show often turn into feature articles that we bring to life in our pages in the weeks and months following an event, so don’t be surprised if you see me jotting ideas down over the three days of the show, and feel free to let me know if you spot a product, service or idea that would be good to share with the entire industry.

Need a lift?

Wholesalers from Windsor to Kingston, St. Catharines to Sudbury, and all parts between are offering customers to “take the bus with us” to get to CMPX 2018. Visit your local participating wholesaler or cmpxshow.com for more details.

International Comfort Products (ICP) recently honoured four Canadian heating and cooling product distributors, naming them Arcoaire, Comfortmaker, KeepRite and Tempstar distributors of the year.

Winning distributors included: Tecnico Chauffage, of Longueuil, Que., (Arcoaire); TTI Climatisation Chauffage, of Longueuil (Comfortmaker); Toronto’s Ontario Heating (KeepRite); and Ontario’s TML Supply (Tempstar). icpusa.com

HRAI investigating heat pump rentals HRAI members in New Brunswick have been concerned about a heat pump rental program offered and administered by Saint John ned Energy (SJE), a municipally owned utility. HRAI objected to SJE’s offering of a heat pump rental program, as it may intrude on the competitive HVAC marketplace. Since its last set of discussions with the utility, updated legislation came into effect in the province stating that municipalities are no longer allowed to operate for-profit corporations, so HRAI is reporting that the City of Saint John, which owns Saint John Energy, a for-profit entity, will have to make adjustments to comply with the legislation. hrai.ca

New rebates in Alberta Energy Efficiency Alberta is expanding its ongoing rebate program to include furnaces equipped with electronically commutated motors (ECM). The rebate program is being run on the same model as the preexisting rebate on tankless water heaters. Any qualified model purchased after January 15, 2018 qualifies for a $75 rebate. Contractors can apply for the rebate on behalf of their customers. The rebate is sent directly to the customer. The online application form is available on Energy Efficiency Alberta’s website.

An awesome intro to the trade Long-time Mechanical Business subscriber Lonny Wright sent us this shot of a hydronic system that he and his 9-year-old son, Gunner, designed and built in Lego. The boiler-based system includes a low-loss header and a mixing valve, and delivers heat to a low-temperature in-floor loop as well as a high-temperature air handler. The pair say their next Lego project is a full mechanical room. Nice work Gunner! And Kudos to Lonny for finding a great way to introduce a young person to the trade.

B.C. targets ASHPs The B.C. Ministry of Energy, Mines and Petroleum Resources is expecting amendments affecting air source heat pumps to be approved and published shortly. Tier 1 of the proposed standard requires split-system heat pumps to have a Region V HSPF greater than 7.1, as tested to CSA Standard C656-14 and a verification mark. This requirement is harmonized with the Federal Energy Efficiency Regulation split-system heat pumps imported into Canada or shipped between provinces. The proposed effective date of Tier 1 is set for June 2, 2018. All stock manufactured prior to the effective date is exempt from the regulation. Tier 2 of the standard is still being proposing to move forward with a January 1, 2020 effective date for the Region V HSPF > 7.39 standard.

Feds to govern AC radio noise?

Saskatchewan adopts NBC 2015 & NECB 2015

The Department of Innovation, Science and Economic Development Canada (ISED) is considering proposing a regulation governing frequency limits for central air conditioning equipment. Such a regulation would fall under the InterferenceCausing Equipment Standard (ICES 003) which sets out technical requirements relating to radio noise generated by information technology equipment. All external thermostats manufactured, imported, distributed, leased, sold or offered for sale in Canada after April 30, 2019 would have to comply with a regulation enforced

by ISED. A CSA technical committee is working to draft Canadian deviations for appliances, including central air conditioners, prior to adoption by the ISED. HRAI has appointed Mark Kendall, of Goodman Manufacturing to participate on the CSA committee. ic.gc.ca

The 2015 editions of the National Building Code (NBC) and National Energy Code for Buildings (NECB) have been adopted in the Province of Saskatchewan. NBC 2015 is now in effect, while Section 9.36 of the NBC and NECB 2015 take effect on January 1, 2019. saskatchewan.ca

Ecobee donates thermostats Ecobee has donated more than 700 ecobee3 smart thermostats to the Toronto Community Housing Corporation (TCHC). The smart thermostats are expected to help improve the energy efficiency of TCHC buildings, improve the comfort of residents, and help advance Toronto’s climate change action plan, TransformTO. TCHC provides homes for almost 110,000 people across 2,100 buildings. ecobee.com

DIGITAL ALERT Vancouver revisits sidewall venting HRAI and CIPH representatives recently participated in a consultation process with industry stakeholders to evaluate the City of Vancouver’s current by-law restriction on sidewall venting of furnaces and boilers, aiming to explore alternate approaches that could be adopted. A bylaw that came into effect in 2015 requires that the exhaust for space heating appliances be directed up through the roof or horizontally through an exterior wall that faces a street. This is not a feasible or practical option for many retrofit applications, however, including those where the existing space heating appliance is already vented through an exterior side wall. HRAI expects to present an alternative solution to the city at its council meeting in March (past press time). hrai.ca ciph.com

Profile Warren Heeley: Having fun and getting things done committees, including the gas installation code committee. He joined HRAI as assistant to the general manager in the early ’80s.

Over the past 35 years at HRAI, he has helped grow the organization from 350 member companies and six employees, to around 30 employees and almost 1,400 members.

We sat down with him to chat about the industry, and some of the advice he has for the incoming president.

Q A

What do you enjoy most about the industry?

Q A

What are some of the challenges facing the HVACR sector?

Our business, the association business, is all about relationships. We need to get the pulse of what our members want, but success comes because of the relationships that we foster with all stakeholders – members, staff, utilities, manufacturers, governments – all stakeholders.

Climate change and refrigerants. Our government has made international commitments on climate change, so we need to figure out how to embrace this and influence the decisions about heating buildings. And we have a phase-down happening with HFCs.

Q A Q A

What’s the most interesting development you’ve seen over your 35 years with HRAI? Something that our industry took on is environmental responsibility. We realized that Extended Producer Responsibility (EPR) is not going to be a short-term thing so I took a personal interest in it, and we have programs for refrigerants and for thermostats. I think that’s been one heck of an accomplishment for the industry.

What advice do you have for the incoming president?

If they are going to be successful, they need to go the extra mile, get out and build relationships. HRAI, despite being a small company, is complicated. Put the time in to learn what’s going on, and don’t stop learning.

FAST FACTS 1. Warren played in a rock band from the age of 14 to 22. His favourite band is Emerson, Lake & Palmer.

2. An arena in Toronto is named for his grandfather, Toronto Park Commissioner George T. Bell.

3. Warren is a huge sports fan, cheering for Toronto and Canadian teams whenever he can.

4. He can wiggle his ears.

Sometimes a good summer job can be a life-changing opportunity.

It was for HRAI president Warren Heeley. A summer job painting a building as a high school student exposed Warren to a world of codes, standards and regulations that set him on a career path that’s lasted for more than four decades.

Heeley, who is stepping into retirement in June, went from painting a building at the Canadian Gas Association (CGA), where his father managed a certification lab, to a few weeks in one of those labs that summer. Once finished university, he found himself back at the CGA, this time as a test technician and working on some of the organization’s

Pressure On THE

IS

I

’m sure that we have all seen and used pressure gauges, both in our lines of work and at home. Your easiest, and likely earliest, encounter with a pressure gauge was quite possibly a basic tire pressure gauge, or perhaps a low-pressure gauge used when filling up a basketball or football with air.

In the plumbing and hydronic heating business, we look at gauges to confirm what pressures are happening in our plumbing piping. A boiler gauge will indicate conditions in the heating system, while other gauges, like the one on a filter, can indicate a number of things, including when it is time to change or backwash the pool filter.

Want to stay cool under pressure? Study up on static and dynamic pressure, engage good installation practices and use good, well-placed gauges.

?

WHY

When you purchase a boiler fill valve or hydronic Wh expansion tank, they are usually pre-set to 12 psi. Why have so exp many manufacturers targeted 12, and not 15 or 18 psi? Good ma question! que practice, 12 psi will usually be adequate for most two-storey In p building applications, since that provides enough lift for that bui water column to hit around 24 feet in height. wa

Expansion, and contraction The pressure in a closed loop system will vary as heat is added or removed from the piping.

If we look at a system starting with a 12-psi static fill, as the boiler heats up, the system pressure could very well rise several psi, depending on the expansion of the fluid as it is heated.

In solar thermal applications, we see the opposite. If you fill and pressurize the system on a warm day to 20 psi, that pressure will drop in the evening as the system cools.

If solar is your game, you may get a panicked owner calling you suspecting a leak in his piping or collectors, at least until they understand the concept of fluid expansion and contraction.

28

M e c h a n i c a l

Some hydronic installers will a adjust their expansion tank pre-charge levels to several pounds below the fill pressure they intend to use. This provides a “safety seal” as the fluid cools. This is a good idea on solar thermal systems, to prevent the gauge dropping to zero under cold conditions.

Solar installers tend to up-size thermal expansion tanks, also, understanding that a large delta T is possible when the panel is in use. The fluid could easily go from an ambient temperature that’s below freezing to above 300°F under stagnation conditions. That is a wide temperature swing to accommodate.

Accuracy counts When you fill, and troubleshoot hydronic systems, make ke ge. sure you are reading the pressure with an accurate gauge.

If the gauge shipped along with a boiler, for example, has had a rough, bouncy journey, it may arrive with the needle lying in the bottom of the face. I like to keep a quality, liquid filled, stainless case gauge on the truck. If you connect it to a female hose fitting you can quickly screw it onto a boiler drain or purge port.

Some boiler fill valves are also available with pressure gauges, so you can confirm that the factory pre-set is accurate, or indicate any changes you make to the valve settings. It can also be used to troubleshoot a system with a leak. Fill the system, shut off the fill or isolation valve, and observe for pressure drop.

Static, or dynamic?

Within a hydronic piping system, we have two different pressures, static and dynamic.

Static Static refers to the pressure of a standing column of water, or fluid, in the system. This measurement assumes there’s no circulation.

The fill pressure is a great example of static pressure.

So, what would be the correct fill or static pressure to shoot for on a hydronic system? The fill pressure is the amount of force needed to ensure that you have fluid in the highest portion of the piping system.

It takes 0.433 psi to lift a column of water one foot (12”), so if you needed to get fluid to the top of a system that is 10 feet tall at its highest point, you would need 4.33 psi on the gauge at the bottom of the system.

Some folks round that 0.433 up to 0.5, which makes the math simple. That 10-foot height would need 5 psi, for example, and if you had a building that was 40-feettall you would want 20 psi for the static reading.

That little extra pressure not only helps to ensure that you have enough pressure to lift the fluid to the highest point. It also helps to ensure that any floattype air vents will seal tightly.

30

The other type of pressure in a hydronic system is dynamic.

The term “head” refers to the mechanical energy present in a fluid, and is related to this dynamic pressure.

When a circulator is started, it imparts energy to the fluid via centrifugal force.

An indication of this added energy would be seen in a gauge at the discharge of the circulator.

When the circulator is off, you can read the static pressure. When it is running, you can read the dynamic pressure.

The energy added by the circulator is to overcome resistance presented by the piping, fittings, valves, boiler, heat exchangers, heat emitters, and anything else in the piping circuit.

This pressure difference can be measured with multiple gauges, a pressure differential gauge, or a single gauge that can be valved to either side of the circulator.

You will want an accurate, reliable reading, so use a high-quality test gauge for this.

By Definition

Dynamic

The circulator is not intended to lift the fluid to the upper levels of the piping in a closed system. The static pressure already has that covered.

A gauge on both the suction and discharge sides of the circulator would give you an indication of the head being added to the system to overcome the piping resistance.

In simple terms, pressure is the application of force to something by something else that is in direct contact with it.

Custom comfort FROM THE GROUND

UP Business vitals: Ironclad Mechanical Plumbing & Heating In Business: 5 years Headquarters: Edmonton, Alberta Employees: 5 Speciality: Hydronic Systems, and Killer Mechanical Rooms

N

ew business is often gained through good old-fashioned word of mouth. Following a discussion between two Sturgeon County, Alta., neighbours about the outstanding design of a mechanical room, Patrick Driscoll soon found himself back on the block for another such install.

The owner of Ironclad Mechanical Plumbing and Heating in Edmonton, Driscoll says it wasn’t that big of a deal. “It’s pretty much a textbook layout,” he modestly recalls. “Anyone [in our business] can do it.”

Early last year, Driscoll was commissioned to work on a 1,900 sq.ft., two-storey garage extension on a 4,000 sq.-ft. house. The garage is where the homeowner works on his beloved collection of vintage British automobiles.

The project involved the installation of a boiler system governing two-zones of in-floor heating, one for each storey of the garage, along with a pair of Wi-Fi thermostats and pressurized air lines for the client’s shop tools.

Epoxy flooring is found on both levels. The main level features a car lift, while the one above it serves as a showroom. Up there, a

Adding a flash of style Although Driscoll claims that the project was a textbook install directly out of the manual, he does admit to adding an “Ironclad twist” to it.

The manifolds are on a 45-degree angle with piping that rolls up into straight lines, and a few pieces of diamond plate were bent at a custom metal shop for the installation’s backdrop.

“It’s a little different from normal. When you get a manifold out of a box they have brackets so that they’re directly facing up and down – nobody really changes that. So, we added a little style to a basic install to make it look a little more impressive.”

VERY

A COMFORTABLE SPOT The system uses a 115,000 BTUH 95% AFUE boiler with an 8:1 turndown ratio, integrated controls and touchscreen, as well as a pair of Wi-Fi thermostats to control the temperature in the garage. Fluids for the in-floor heating runs through half-inch PEX. While some contractors will suggest heat lamps or air handlers as inexpensive ways to heat garages, Driscoll prefers to direct homeowners to go a step further and put in the under-foot heating systems.

“The first time they get down on the floor to retrieve something, they’ll realize how comfortable it is.”

wall-mounted 60” interactive touchscreen allows the homeowner to order parts or display vehicle schematics.

Ironclad’s boss loves working on these types of projects, partly because he knows how much enjoyment homeowners ultimately extract from the finished product. “That experience of lying down on a warm floor to work on your car for the first time is what hydronics is all about,” he explains.

The homeowner, who was so impressed with his neighbour’s mechanical room layout that he opted for the same equipment and expertise, is an architect who has an appreciation for exceptional design. He reached out to Driscoll, who delivered, earning him the maintenance contract for the entire house shortly after the boiler system install.

“That was kind of nice,” says a smiling Driscoll.

“You want the client to be pleased with how the room looks, so you need to understand them,” he adds. “We make the room look good because we’re trying to promote maintenance. If you feel comfortable walking into a room and looking at all these components, instead of an intimidating mess with criss-crossed piping and wires, it can be inviting and something they’re ultimately proud of.”

Some homeowners plan to keep their heated garages at 0°C to 5°C until they need to work in them, but he helps them realize that by keeping their garage at 21°C, finishing their floors in epoxy, and adding a TV, they can truly create another living space.

“It becomes a second man-cave – or great doghouse,” he jokes.

DRISCOLL ON CONNECTIVITY If your system goes down, it’s nice to get an alert on your phone. Consumer expectations are evolving and this sort of connectivity is becoming increasingly standard.

“If you get a message telling you it’s time to change your furnace filter or that the temperature is down in an area of your home where it’s set to be higher, it promotes maintenance over people simply shutting the door to their maintenance room and never going in,” Driscoll weighs in.

“You don’t really think about the functionality until you have it. Once you do, you find yourself checking it every so often.”

SMALL DETAILS; MAJOR IMPACT

PROJECT PROFILE

Over the years, Driscoll has learned that seemingly small details can have a significant impact on a system when it comes to boiler installations and how well the equipment functions. He recalls how a minor adjustment on another project made all the difference in the world.

“We fired up a boiler after the install, but quickly realized the system wasn’t quite running properly,” he explains.

“I called tech support because of an ignition error. There seemed to be a backdraft affecting the system, but locating the issue proved challenging.”

The technical support representative asked Driscoll to describe what the venting looked like.

Like checking the weather forecast on a phone, he finds that his customers are actually using technology to check on their homes.

“Technology changes how we do things,” he says.

“People didn’t consistently check the weather until it was on TV. Now weather is posted online and every morning people check their weather app. Now we’re checking the temperatures in our homes while we’re away at work. Connectivity is evolving our behaviour.”

Precision

“It appeared fine. I didn’t use too many elbows and had at least another 75 feet of flexibility to go. I also sent over a picture of the termination point, which came out on a 45-degree angle from the house.”

That’s when the source of the problem was discovered. The termination point required a small pipe extension, just a six-inch piece, to run horizontal with the ground. Without that, the system was running into issues caused by the wind.

In this case, the house was facing northwest, and gusts of wind were catching the 45-degree final termination sidewall venting, creating the backdraft. Once the horizontal piece was in place, the problem vanished.

PLANNING MAKES

perfect W

hether it be for upgraded aesthetics, updating to current code, fixing broken equipment, or targeting overall efficiency, thousands of plumbing renovation opportunities exist within commercial buildings all across Canada, and building owners are in need of knowledgeable contractors who can provide a viable plan for these renovations.

Unlike with new construction, retrofit projects rarely start with the advantage of having the plumbing systems meticulously documented in a set of blueprints, however. New equipment, often with specifications that have changed since the existing faucets and fixtures were installed, needs to fit into existing—and often unknown—conditions, both upstream and downstream.

That’s why it’s important to talk to the people who know the building. Talk to building owners, facility managers, maintenance personnel. Anyone who knows the history of the building’s plumbing, quality of the potable water, any floorplan adjustments, maintenance practices and any chronic or recurring problems, can help build a picture of what to expect.

And an honest appraisal of the current system can help avoid situations where the customer says, “Everything was working fine until you replaced the fittings.”

A properly executed plan that looks at current code requirements, the existing piping layout, and even the availability of commercial water efficiency rebates, will dramatically increase the chance for a successful project.

Commercial water savings projects are not only financially smart, they are environmentally responsible, and in some municipalities, legally mandated. Today’s technology can help achieve real and meaningful savings, but the reduced water volume can have unintended consequences if the plumbing system isn’t capable of adapting to the lower flow. With foresight and planning, risks can be avoided and the goal of water savings can be achieved.

Stop the leaks 36

M e c h a n i c a l

LOOK FOR REBATES We’ve all seen municipal government programs aimed directly at homeowners, but did you know that there are hundreds of commercial programs across Canada as well?

Many of these programs are similar to residential ones, where they offer cash rebates for high-efficiency toilets.

Tapping into one of these programs is a simple way to create savings and show a potential client that you care about their bottom line.

Natural Resources Canada has an online, searchable program directory that can be found on its website, www.nrcan.gc.ca.

A leaky faucet or toilet stop valve can add up in a hurry. A tap that drips six drops a minute will lose 1,200 litres of water annually. Add that up over a few faucets in a building and you’re looking at a potential disaster.

Including new shut off valves, supplies and stops should always be a part of any thorough renovation plan.

COMMERCIAL PLUMBING

WHERE IS THE WATER GOING? As part of any proper building water audit, it’s important to look at the entire building’s use of water, from cooling towers to fixtures to drinking fountains. Many public facilities now have water bottle filling stations which weren’t around 20 years ago, so the overall building consumption could be higher than when the building was new.

Assess,

assess,

assess

By looking at all areas of water use and calculating the days per year that the building is being used, and the approximate number of users annually, it is possible to can get a solid baseline of consumption.

Conducting a thorough assessment means inspecting the plumbing system and measuring as many performance variables as possible. Here are a few checkpoints to include when conducting an audit of the existing system.

• PRESSURE Static pressure, working pressure and recovery help determine a system’s response and capacity, and are a good first item to check, but static pressure readings are not a tell-all for the health of a system.

Very high static readings, above 80 psi, can be a warning sign of failing pressurereducing valves (PRVs) or, much more concerning, a volume and capacity problem. The building’s maintenance people may have purposely increased the pressure to try to overcome problem areas in the building.

Keep in mind that while typical plumbing code specifies a maximum pressure of 80 psi at the fittings, branches along the system may have higher pressures.

• PIPING DIAMETER It would seem logical that, by taking the fixtures down to 1.28 gpf, the demand on a plumbing system would be reduced, however the opposite is true.

With the new fixtures, the same amount of waste must be evacuated with half the water volume and, in many instances, a smaller water spot and trapway.

Water closets previously used up to five gallons in 90 seconds to flush and transport waste. Now, 1.6 gallons is used in 20 seconds, so drainage piping may need to be re-examined.

38

M e c h a n i c a l

Using the building’s same usage parameters, but calculating the water use data with high-efficiency plumbing products, it is easy to show a prospective client just how much water they can save on an annual basis. Add in the municipal water rate and you can show total dollar savings and payback rates as well.

• PLUMBING LAYOUTS AND L FIXTURE COUNTS Is the building plumbed correctly with main lines, and are all branch lines sized correctly to meet the demands of the fixture counts?

• CHECK THE HISTORY Have there been additions to the building, or changes to the plumbing system that were done without increasing the plumbing system’s capacity, both for delivery and drainage?

• WATER QUALITY The quality of the water in a building is often overlooked prior to a renovation.

In piston valves, for example, high amounts of sediment or sand can shorten the life by wearing the lip seal. This results in a shorter flush cycle, making it necessary for a double flush to clear the bowl.

And water with high levels of chloramines can attack natural rubber components found in some piston and diaphragm valves, so a water quality test can help with component selection—to help fix problems before they start.

B u s i n e s s

0 4 . 1 8

• FIXTURES AND VALVES Document the manufacturer and model number of all the equipment to be replaced and assess the age and condition of the equipment. Include such details as the flush volume rating and note any signs of leaking, as well as the maintenance record.

The downstream side of the equation is just as important as the upstream.

Depending on the age of the system, the original waste line carry calculations were probably based on 4.5 gpf.

Through attrition, the original fixtures may have been replaced to 3.5 gpf or 1.6 gpf. Further reducing the water to 1.28 could result in downstream problems.

Red flags include: problem or chronic line blockages or toilet backups; poor pipe conditions like corrosion, leaks and cracks; long horizontal waste line runs; and signs posted in restrooms warning what NOT to flush down fixtures.

SOME LIKE IT HOT OR NOT

I

t’s hot out, too hot out for this foolishness.

I’m dripping sweat, and I mean leaking from every pore of my body, and I’ve been awake now for about 30 hours. I feel like I’m hovering somewhere between Bruce Willis squirming through a tight duct in the original Die Hard saying his famous phrase, “Come out to the coast, we’ll get together, have a few laughs,” and an astronaut trying to breath in his space suit while an alien is dripping toxic fluid on his body.

I never thought I would ever have anything to do with potassium hydroxide, also known as KOH, or caustic potash. I never paid enough attention in chemistry class to even know what it was. Of course, as fate would have it, I would end up getting up close and personal with KOH in the second year of my plumbing and gasfitting apprenticeship.

CLEANING UP THE KITCHEN Apparently, the number 1 cause of fires in restaurant kitchens is grease, and these usually start in the washdown ventilation hood.

Back then, I didn’t even know what a washdown ventilation hood was, let alone how to clean them. After a quick, 10-minute education, I was sent with a labourer to Banff to clean a few of them with our new pressure washer.

I won’t name the hotels we worked, but they were nice, and I wanted to impress as we might be able to pick up more plumbing work. The problem was that we would have to work all night, followed by all day, and all night again, all in a row.

40

M e c h a n i c a l

The plan was to wait until the kitchen shutdown around midnight, then shut off all the gas to the kitchen appliances. We would turn the jet spray on in the cube van and induce the potent heavy-duty toxic grease cleaner (KOH). This chemical is quite strong, due to the caustic potash that is reactive to water. It is corrosive, and harmful if swallowed. I definitely had no intention of swallowing it, but it also wasn’t exactly a skin moisturizer, so we wore full body suits and complete face shield head gear, something like out of the movie E.T.

B u s i n e s s

A Calgary plumbing company that I worked for briefly when I first moved to Cowtown had purchased a jet pressurized system and had it converted into a cube van. Its main function was to assist in the thawing of frozen storm sewer lines during Calgary’s deep freeze winters and chinooks.

With the weather having changed to a hot summer, there was little work for this machine that we had been charging out at $75 an hour. Rather than let it sit idle for the summer, my boss had this brilliant idea to use it for the cleaning of greasy washdown ventilation hoods in commercial kitchens, so there I was in 1982, trying not to think about the tight spots I found myself in.

How to save money on trench drainage

The washdown ventilation hood

F

or those of you that have yet to have the pleasure of working with this equipment, a washdown ventilation hood is a stainless steel canopy installed with a 1/2” copper hot water line feed and a 2” type M copper drain that goes to the grease interceptor or indirectly into a 50-gallon removable drum. Its function is to remove the evaporated grease from fryers or cooking ovens.

Twentieth Century Fox

As the fried grease evaporates into the huge canopy, it settles into an interior stainless steel trough and is sprayed with hot water (usually 170 to 180°F) to keep it flowing down the trough and into the copper drain pipe.

There are two different spray nozzles associated in the canopy, one type of spray is just hot water, the other spray is a chemical or fire retardant that is necessary for fire safety, and is hooked in conjunction with the gas valve to shut that down during a fire.

Typically, we need to run that drain pipe at least five feet, or cool it down in some other acceptable fashion, before it is drained into the grease interceptor since the interceptor is useless if the temperature is too high.

Needless to say, it gets greasy and disgusting if it is not cleaned enough. Restaurants that use a lot of grease should be cleaning the filters and ducts at least every two or three months. Back in the ’80s, a lot of washdown ventilation hoods were not actually automatic. They, and the ducts, had to be cleaned manually with a spray gun.

Remember a good night’s sleep is in THE CODE.

NOW BACK TO ME IMPERSONATING BRUCE WILLIS… On the last night of almost 30 hours of working with no sleep, I found myself almost finished, but encased inside a 36” greasy duct in the ceiling.

I’m dripping sweat and feeling greasy, trying to spray every spec of grease off the duct – all while my jet sprayer kept overheating and shutting down. I would say this was one of the worst jobs I’ve ever done but, finally, after hours of hell, we finished around 5 or 6 in the morning.

So, we quickly clean up the place, take down all the plastic, and I commence with turning the gas back on.

I had prided myself in never having a gas accident or explosion in my short trade experience, so I carefully turned on the gas and commenced lighting the gas stove top elements and the fryer pilots.

Even though I was exhausted, I was happy to be finished and could not wait to shower and crawl into some cool clean sheets in the hotel we just cleaned. My helper and I finished packing up and checked in.

At about 7 a.m. I get a phone call, just as I was about to fall asleep. It was the kitchen cook. I could barely make out what he was yelling, but it sounded like he may have burnt or singed off his eyebrows while trying to light the ovens.

I believe I may have forgot to light the pilots in the ovens, I just lit the range element pilots on top. He was not very happy as he explained the quick explosion that occurred from the accumulated gas in the ovens.

I profusely apologized and ran to the kitchen and made sure all was well. Then I hit the main office at 9 a.m. to quickly get my cheque, which I discounted for the incident. Luckily all were appeased, although we did end up sleeping at another hotel.

Maybe this is why I specialize in teaching plumbing code instead of gas code!

Remember a good night’s sleep is IN THE CODE.

TURNING WRENCHES AT

94

Saskatoon is home to a local industry legend.

While many dream of retirement as they hit their mid-sixties, at the tender age of 94 Lorne Figley is still on the tools, operating his one-man business, Broadway Heating Limited, as he has since the 1950s. The world’s oldest active plumber, an achievement confirmed and certified by Guinness World Records, he has no plans to trade in his toolbox for a rocking chair any time soon.

SPECIAL RECOGNITIONS

A FAST LEARNER Figley was born to a family of farmers in Tuberose, Saskatchewan in 1924. “It’s a town that has long since disappeared,” he said during our recent interview with the Mechanical Business subscriber.

Able to read and write by the age of four, he completed Grade 1 and 2 in a single year, which he also did for Grade 7 and 8.

The fast track through the education system made high school life a little daunting he recalled. “I was always scared of the other kids because I was so much smaller,” laughed Figley.

Later in life, he continued to show an aptitude for processing knowledge, acquiring numerous skillsets. Not only is he a plumber, Figley has journeyman credentials for sheet metal, steam fitting/pipefitting, refrig-

eration and air conditioning – all of which he continues to use on a regular basis. He says it was a matter of seasonal practicality.

“When I first started in the ’50s, mechanical contractors were typically closed for the season by December 12 and didn’t reopen until April because it was so cold.

Although I had my journeyman ticket in sheet metal, the work shut down in the colder months and I was kind of forced into the plumbing trade,” he said. “Later, I took other trades to allow me to work enough through the winter.”

B u s i n e s s

0 4 . 1 8

Saskatchewan Polytechnic recently honoured Figley with a Lifetime Achievement Award.

The school also honoured his contribution to the trades by naming its plumbing scholarship after him. The plumbing apprenticeship student with the highest exam mark receives a $500 prize. Last year, Figley arranged for the creation of a similar scholarship for the school’s top sheet metal student.

“My father is an amazing man, whom I feel deserves to be recognized for his life achievements,” says his adoring daughter, Tricia Koobs, who was responsible for putting her father up for the Guinness World record in 2015 as a birthday present. “He is the type of everyday person that has been the backbone of Saskatoon’s development – truly one of the ‘unsung’ heroes.”

This year, Koobs is submitting documents to Guinness World Records to help keep her father’s record standing.

TAPPING INTO TECHNICAL SKILLS

Did you know Waterman-Waterbury International Heating Company manufactured heaters for Saskatchewan’s rural schools, and also made iron lungs, prior to its bankruptcy in 1962.

During the Second World War, Figley served with the RAF’s 664 Squadron, which was tasked with helping to liberate Holland.

“I joined the forces in 1942,” recalled Figley. “I was sent to Europe in 1944 and became part of an air observation post group. They used our unit to knock out German coastal bunkers. Our unit flew small planes – capable of 35 mph – that would direct the shelling from different artillery units.”

was to put the radio on that frequency and install it on the plane’s mounting bracket.”

Throughout the war, Figley served as a radio operator, driving a three-ton truck full of repair equipment and radios.

“A motorcycle rider would come in at 6 a.m. with a frequency the artillery unit was going to use that day. My job

Shortly after returning from the war with an acumen for all things technical, Figley soon found himself working for the Waterman-Waterbury International Heating Company, where he completed his sheet metal apprenticeship.

I take a two-month fall prevention class in Kinesiology at the local university every few years – and I haven’t fallen down once.

A LOT OF CHANGE Figley has witnessed many changes to the mechanical trades over the years. He recalls using lead joints in his pipe fittings, and still finds himself replacing them to this day.

“We took lead out of our soldering in the late ’80s and now we use silver solder. I also remember putting in coal furnaces way back in the ’50s.”

He points to the health department’s regulation of potable water as being one of the biggest improvements in plumbing over the years. Another positive was something achieved in his home province.

“In the early ’50s, the government put in gas lines to every town and village in Saskatchewan for free,” he fondly recalled.

“This was something no other province ever attempted. We were very lucky.”

A BUSINESS STARTUP In 1951, Figley purchased the assets of a business in a Saskatoon strip mall, which he eventually named Broadway Heating Limited. His company installed many of the original commercial heating systems in several of the city’s older buildings, something that still gives him a feeling of pride and accomplishment.

Shortly after buying his business, Figley expanded the scope of operations, hiring a plumber under whom he eventually apprenticed. Gradually, over time, he added his other Red Seal certifications.

Over the years, Broadway Heating Limited grew in size, peaking at around 10 employees and five trucks in the ’60s and ’70s. While no longer that size, he’s kept the company intact, and himself busy.

“Over the past 25 years, I’ve looked after a group of apartment buildings,” he said. “Most of my current work is doing assessments on air conditioning, heating and ventilation.”

Just don’t dare ask him if he is retiring anytime soon. Pressed on the subject, he drolly replied, “Nope!”

REFRIGERATION

SUPERCRITICAL CO2 in transcritical refrigeration:

I

n Part 1 of this discussion (see Mechanical Business, January/ February 2018) we discussed some characteristics of transcritical systems and supercritical CO2.

Did you know?

In the refrigeration world, CO2 that meets certain required purity levels is designated R744. When purchasing CO2 refrigerant, it is best to refer to this refrigerant as R744 in order to infer the required purity level.

For this article, we will discuss how to plot and calculate the optimum pressure (POPT) for the high side of the system. But first, we need to establish the meaning of this concept.

With respect to the capacity and power consumed, there is an optimal coefficient of performance (COP) as shown in Figure 1. This means that there are a set of conditions that result in the highest refrigeration effect per unit power input to the compressor. Note that maximum capacity is not achieved at POPT, but at a pressure that is somewhat higher than POPT.

There are a few options that can be used to determine the optimum gas cooler pressure. The most accurate, yet most time-consuming, approach is the iterative method. To do this, we plot the high side pressure at increased steps of approximately 10 psi. With each pressure increase, the COP is calculated.

COP is equal to the NRE divided by the power input to the compressor.

Using the standard Mollier diagram to plot transcritical cycles can prove to be a challenge, however, due to the large gap between constant pressure values. In the logarithmic version of the diagram, the constant pressure line that corresponds to 1,000 psia is just below the critical point. The next constant pressure line above this is 2,000 psia. During transcritical operation, a system operates somewhere in between these two points.

Although more data can be presented using the logarithmic approach, this makes it very difficult to accurately determine values for pressure.

Therefore, a diagram with a higher resolution would be required.

This is a Mollier diagram for R744 that has a linear pressure scale. As you can see in the diagram, the constant temperature lines (isotherms) appear in only 5°F increments between 80°F and 120°F. This will also enable us to plot the transcritical high side conditions more accurately.

REFRIGERATION Once we are able to successfully plot the transcritical processes on the PH diagram, we can then take a closer look to see which high side pressure will achieve the greatest COP for a given gas cooler outlet temperature.

The refrigerant temperature leaving a gas cooler will generally be around 3°C higher than the entering air temperature. Note that the specific enthalpy values are listed along the horizontal axis of the Mollier diagram.

FINDING THE SWEET SPOT In Figure 2, the first process indicated by the solid line shows the evaporator located between points 1 and 4 and the compression process between 1 and 2.

The subscript L indicates a lower gas cooler pressure than the base system, while the subscript H indicates a higher gas cooler pressure than the base system.

in BTU/lb. by the heat of compression, also in BTU/lb. Note that the energy efficiency ratio (EER) is calculated in a similar way and is an alternate method for expressing the efficiency of the cycle. The total cooling capacity in kBTUH can be divided by the compressor power input in kilowatts.

FIGURE 2

If we draw vertical lines [constant enthalpy] between the conditions entering the evaporator, entering the compressor and then leaving the compressor, we can see which system provides the greatest net refrigeration effect (NRE) for the least amount of power input. In this case, it is clear that the base process has the higher COP. The high side for this process is plotted at the constant optimum pressure value between points 2 and 3.

In order to calculate the COP, divide the NRE

USING THE MOLLIER Another method of graphically expressing the approximate POPT is to locate the 0.9 constant quality line at the point where it intersects the evaporating temperature inside the two-phase region. This is illustrated in Figure 3 on page 52.

From this point, draw a line up to the isotherm that represents the temperature of the refrigerant leaving the gas cooler.

Your line should intersect with the curved portion of the isotherm, as indicated in the diagram.

R-22 is best for R-22 equipment.

If you need to change,

Arkema has your R-22 RetroďŹ t Solution

After plotting this line, we can then draw a horizontal line through the isotherm and to the vertical axis, where we can read a pressure value of approximately 1,275 psia.

In addition to using the Mollier diagram as a tool to calculate the optimum discharge pressure for the transcritical system, there are some algorithms that can be used to estimate the optimum gas cooler pressure.

The algorithms shown are also used to position gas cooler outlet regulators, which we discussed in a past article.

Since the ambient temperature and reclaim heat sink temperature will vary, the optimum high side pressure must be calculated on a continuous basis as the system operates. Therefore, in order to achieve best efďŹ ciency, some form of algorithm-driven regulator will be required.

This is how we vary the high side pressure in transcritical systems. The product shown on the next page is one example of such a regulator. These types of regulators also require a controller

Don’t forget to convert temperatures before applying a formula. Also note that none of these algorithms should be considered to be 100% accurate. They are simply used to give us a reasonably accurate indication of the optimum high side pressure.

The most accurate method will be the iterative method, providing that a sufficient number of calculations have been performed.

Using the plotting method, we can determine that the optimum mum high pressure is approximately ely g 1,275 psia, or 87.9 bar. Using the first formula, we get 89.6 6 bar. With the second and third rd he formulas, we get 86.4 bar. The difference between the threee refore methods is quite minor, therefore we will come up with more or less in the same result with each method.

Proper airflow is no fictional unicorn E

nsuring proper airflow is one of the most important aspects when installing an HVAC system. Air that is not properly distributed will cause uneven heating and cooling, and will place undue stress on the system.

Unfortunately, unlike other parts of the system, air distribution cannot be seen, so it is extremely important to have a thorough understanding of how air flows in a duct system, and what causes it to be properly distributed. This knowledge will help with successful troubleshooting of air distribution problems.

C H E CK Y OUR ESP It is easy to diagnose a burnt-out blower motor, but understanding why the motor burnt out and fixing it is what separates a technician from a parts changer.

External static pressure (ESP) tends to be the unicorn of our industry but it’s really not. The equipment will tell you what ESP it is operating at.

Using the following formulas, you can calculate the exact CFM the motor is producing, whether you are on a gas furnace or an electric strip. This, along with the manufacturer’s blower curve, will tell you the ESP the blower is working against.

Part of the calculation is to determine the properties of the air to understand the amount of force required to move the air. This will then enable you to calculate the proper CFM. It is also important to remember that the way a blower is designed dictates the amount of flow, or CFM, it can deliver at a given static pressure.

Air type affects performance When designing a duct system, it is important to account for the type of air – wet or dry – that will be distributed through the system. Humid air is heavier and thus harder to move through the system.

In a perfect world, measurements would be done to understand air density prior to designing the system, to ensure the ductwork and HVAC appliances are sized properly to distribute air evenly.

As we all know, however, we do not live in a perfect world and technicians often end up working on homes where the rooms farthest from the HVAC appliance are at a different temperature than the ones closest to the source. Part of the troubleshooting should therefore be to investigate what is causing the uneven airflow.

FORMULA: If you know the BTU output, you can calculate the CFM as follows: Using a 100,000-output furnace producing a 54˚ temperature rise,

For electric heat, use the following formula, where the Temperature Rise (TD) = 50, to calculate the BTU and CFM:

M e c h a n i c a l

B u s i n e s s

0 4 . 1 8

Once you know the system’s ESP, look at the velocity of the air being delivered. The recommended velocity for supply trunks is 700 to 900 Velocity Feet per Minute (FPM). Less than 700 FPM will cause uneven air distribution while FPM higher than 900 will create high noise levels.

Many systems include the use of volume dampers to adjust airflow due to aesthetics, plumbing or electrical. All of this will have a detrimental outcome on the velocity of the air delivered to the register and improper air delivery will have a negative impact on the customer’s ultimate indoor comfort.

HVAC

MYTH VS FACT .

CHECK THE THROW

MYTH: Hearing lots of airflow moving through the duct system means the system is moving lots of air and the air is distributed evenly.

Another aspect of a duct system to investigate is the throw, or the distance the air needs to travel across a room before it begins to stratify (layering of air). With proper throw, the air will travel approximately halfway across the room before it stratifies causing the air to reach the far side of the room with a low noise level at the supply register.

FACT: The velocity pressure in a system regulates the speed at which air moves. A supply duct should only be moving air at a maximum of 600 FPM. Since CFM decreases at high velocity, hearing the air move through the duct system means you are moving less air at a higher speed, forcing the system to work harder and the air to be distributed unevenly.

If the throw is too weak, the air will stratify too quickly and the air will fall before reaching the other side of the room. If, on the other hand, the throw is too strong, it can cause a lot of noise at the supply register and potentially cause the room to be drafty.

Imagine you are driving down the road and you slightly crack open the car window. This creates a lot of noise while allowing only a small amount of air into the car. Alternatively, if you were to roll the window all the way down, you will feel a lot of air rushing into the car with less noise.

HVAC MYTH: An Electronically Commutated Motor (ECM) will fix all ductwork issues.

FACT:

MYTH: If there is not enough airflow on a PSC motor, setting a higher speed will solve the problem.

FACT: Setting a Permanent Split Capacitor (PSC) motor on a higher speed will load the motor and move even less air as a PSC motor works against a high static pressure. This becomes evident when performing an amp draw on the motor; as the static pressure increases, the amp draw decreases.

Part of the problem with improper airflow is that it increases the energy draw, which is reflected on the homeowner’s energy bills. While an ECM is designed to maintain a constant CFM, if the fundamental issue causing improper air flow is not resolved the watt draw on the motor at high static pressures will continue to increase the energy use, thereby negating the expected savings of an ECM.

FRONT AND CENTRE IN BUILDINGS OF THE FUTURE

C

onsider the building of the future. Is it easily reconfigured and upgraded to accommodate a variety of needs, adapt to changing conditions and improve the performance of the building itself? It should be.

Efficient HVAC systems, such as those that rely on radiant heating and cooling distribution, are currently designed with this futuristic image in mind. Each component is selected, installed and operated to meet energy consumption goals and adapt to the ever-fluctuating system demands.

For circulators, this means they will operate at higher levels of efficiency over a broader range of operating conditions and adjust speed to react to system changes.

With the introduction of smart technologies and potential regulations coming in the future, the next generation of circulators will be of interest for some time to come.

Forward thinking > The IoT also enables predictive control. For example, this could occur when BMS data is linked with online weather forecasts and building usage patterns to adjust HVAC and lighting systems to ensure building occupants are more comfortable and energy use is optimized.

62

M e c h a n i c a l

B u s i n e s s

SMART TECHNOLOGY As we envision the building of the future, it should contain innovative technology and applications that react to occupant behaviour and expectations, and tailor energy and resource consumption to meet these needs.

The good news is that many existing buildings are already integrated with smart technology that ensures greater connectivity through the Internet of Things (IoT) – and demand for these intelligent products is growing.

According to recent figures and prognoses, the number of connected things is projected to increase at an annual compound rate of 23.1 per cent between 2014 and 2020, reaching 50.1 billion things in 2020.

Circulators today contain more programming than ever before to enable real-time communication between the building and its administrator. The circulator provides timely updates so facility managers can remotely monitor what the pump is doing any minute of the day or night.

The advanced analytics generated by integrated drives with sensorless technology also incorporate algorithms that enable the circulator to monitor its power requirements and automatically adjust to meet system demands.

Many large circulators contain BACnet capability, which enables them to be linked to a building management system (BMS) to increase communication with other building systems. Instead of monitoring only individual functions, data from the circulators can be connected to other components of the building, like lighting controls, to adjust HVAC and lighting systems to meet building needs.

CONSERVATION STANDARDS

What’s an ECM?

The most efficient circulators on the market contain ECM technology, and in the not-too-distant future, it is expected that all circulators will be required to use ECM technology.

To prepare the industry for this generational technology change, a number of industry groups and organizations have been meeting to discuss test procedures and energy conservation standards for circulator pumps.

In the meantime, ECM circulators have already begun replacing circulators with induction motors in the marketplace. Permanent magnet motors are the technology of choice because they achieve higher efficiency — helping to boost system performance by up to 85 per cent.

Circulators operating at variable speeds provide greater system control and flexibility compared to constant-speed circulators.

Additional advantages of newer ECM circulators include a permanent magnet in the motor to help reduce friction losses in the circulator pump, quicker start up in a system and easy-to-read interface displays. ECM circulators can readily be programmed with a few button pushes and the pump’s interface clearly displays the flow rate, head, speed and power consumption. As we look to the future, circulators will play a key role in making building systems smarter and more connected than ever.

An Electronically Commutated Motor (ECM) is a brushless DC motor where the direction of electric current is switched electronically.

The switching of current is technically known as “commutating,” which is where the C in its name comes from.

In the HVAC industry, an ECM is generally a brushless DC motor with an integrated electronic control module. Having a permanent magnet on the rotor eliminates the need for input power to magnetize the rotor. On the other hand, a traditional PSC motor consumes more energy by simply having to produce a magnetic field by inducing a current into the rotor, whereas an ECM uses permanent magnets, giving it an inherent efficiency advantage.

In operation, stator coils generate a rotating field, and the magnet on the rotor reacts with this magnetic field to start the rotation. A microprocessor is used to control the motor and keep stator current in phase with the magnets of the rotor.

TEMPERATURE TROUBLES After listening closely to an unhappy happy hydronics owner, you start your ur troubleshooting process. The customer has a pretty good idea where the problems are, so you go to o the mechanical room and lookk at the install. You channel your Dan an ” and Holohan and “think like water” ow “think like air” to figure out how pes, the fluid moves through the pipes, and how the air can get out.

1. It looks like the previous contractor added dd d an auto vent up above b the A/H to let the air out to cure the little or no heat in Zone 1.

That didn’t work, so he then added a larger three-speed pump and selected high speed. If that worked, you wouldn’t be here, so you suggest: a) Maybe the coils are plugged. b) The pump is too large, go back to the original. c) The air vent is not working. d) Do the math and set the fill pressure to 20.5 psi, remove the expansion tank and charge to 20.5 psi, and install a pump that will deliver 4.5 gpm at the desired head loss.

a) Set the pump to proportional pressure and select the correct curve based on head loss. b) Leave it at constant pressure but select the highest curve. c) Set it on infinite speed and dial in the proper temperature drop. d) Use the auto mode. e) Use a delta T pump.

Search some sites in your region and you’ll likely find that many competitors aren’t using a refined blogging strategy in their marketing mix. Done well, writing a blog can help position your business and crew as reliable subject matter experts, and can drive sales opportunities for your business.

too worried about structure and formality. Blogs are casual, and reflect a genuine voice. If you write the way you speak, odds are you’ll just need a bit of a final polish to clean it up and get it good to go.

Some tips to guide your blogging strategy Not all blogs are created equal, nor fuel the same results. Common mistakes include poor writing, content that isn’t rich in the keywords necessary for search engines, and losing the momentum to keep it moving.

Regular readers of my column may notice a difference in how this one is written. I’m separating every paragraph with sub-heads. They’re not really necessary, but they accommodate the skimmer, now a common way to consume web content. Make your key points in sub-heads assuming only about half your readers will actually read the paragraphs underneath. Effective sub-heads also help with your SEO.

Marketing with DOUG MACMILLAN

Get ideas from customers and co-workers Keeping up a healthy list of relevant topics is one of the hardest parts of a blog strategy. Look to the things that happen every day in your business for guidance. What questions do customers ask you the most? Where is there confusion? What do your techs complain about that a blog might help make clear? Are there specific subjects on social media that you can build on?

Include an image Stay in your wheelhouse Focus on writing about what you know, while being sure to use plain language that is accessible to people who don’t understand it the way you do. If your keyword research points to topics that don’t necessarily fit within your knowledge base, invite a guest blogger (an employee, supplier, manufacturer or business partner) to provide an article. The bonus with this is that when you share it around your social media channels, by tagging your guest, you’re inviting that person to also share the column to his/her followers.

nce mainly used for commercial plumbing and hydronic heating systems, the expansion tank is fast

becoming a necessity in smaller residential buildings as well.

When water enters into a structure equipped with a check valve or backflow preventer, that plumbing system should be considered a closed system. Since pressure can build when water in a closed system heats up, the system must be outfitted with components, such as expansion tanks, that provide an outlet for any excess pressure.

SERVICE ACCESS VALVES simplify maintenance ance

“Now Now that there are concerns about poisoning and cross-contamination, water meter companies now make meters m with a back-flow preventer built in,” says Mike Breault, Watts Canada’s senior technical trainer and instructor. “Plumbing codes are starting to

Most new homes should be going in with back-flow prevention, depending ho th municipality.” on the In a closed potable water system, one expansion tank can service multiple mu water heaters, multiple small tanks can serve one large water wa heater or multiple tanks can service multiple water heaters.

“Service valves should ld d be installed with the expansion pan nsion tank so you don’t have to shut down the entire system and drain it. It’s a few extra bucks, but it’s the right way to do it,” says Breault. “Remember, if you are planning to use a regular ball valve, the handle should be removed and hung nearby. If you do not, there is a possibility that you may accidentally isolate the tank from the system rendering it useless.”

every backflow device.

“If you have a water main coming into a complex, and every townhouse has its own backflow preventer to isolate each unit, you need an expansion tank for each unit,” explains Breault.

“With some of the new heating systems [going into homes], such as combi-boilers, expansion tanks are required,” adds Claudio Spagnuolo, a plumbing inspector for the City of Brampton. “Whenever you’re dealing with potable water, all the components have to meet NSF 61, which ensures there’s no lead or contaminants in the materials that could pollute the water.”

Using certified POTABLE TANKS There is a difference between expansion tanks made for potable and non-potable applications, and getting it wrong is both dangerous and violates code.

“Heating tanks do not have any kind of potable certifications and there is no coating on their metal,” says Breault. “This means something could leach into the water, like rust. I’ve heard horror stories of people putting in basic heating tanks because they’re cheaper.

They’re cheaper because they’re not certified and are not suited for water that’s being consumed.”

By contrast, a potable tank is designed to prevent leaching. While you do pay more for the tank, it has special coatings to resist rusting and typically has a more robust bladder system.

Improper tank use is one of the most common mistakes Spagnuolo comes across when inspecting potable expansion tank systems.

“I’ve seen some tanks that should just be used for heating systems that were used on potable water, and I’ve made them switch them out,” he says.

78

Alternatives to expansion tanks As it stands, the temperature and pressure relief (TPR) valve on a water heater is insufficient to be considered a thermal expansion device. If water is allowed to continuously drip from the TPR relief valve, minerals from the water can build up and block it. Without an alternate outlet, this would lead to much bigger problems.

There are other pressure-relief options beside expansion tanks, however. One alternative to a tank is a pressure relief valve.

“It’s as simple to install as a valve,” advises Spagnuolo. “There is a drain on it that should lead water to a hub or floor drain just in case it goes off, so you don’t flood the floor.”

While similar to a water heater’s TPR valve (which is controlled by temperature and pressure) a pressure relief valve is set to a specific pressure. When a closed system reaches that pressure, the pressure relief valve opens, releasing pressure and water, which must be properly channelled into a nearby drain. Once it the pressure drops, it closes.

Another alternative to the expansion tank is a ball cock relief valve, which is installed in a toilet tank. It limits and governs a domestic water system’s pre-set static pressure to 80 psi.

Still, Breault believes water tanks are the preferred choice over the other options. “All these alternatives are wasteful because you are expelling water that you’ve paid to heat,” he explains, “which is why I always recommend the expansion tank.”

Tank installation tips

Sizing matters

In scenarios requiring the installation of a new expansion tank, Breault offers some advice.

A larger than required tank isn’t an issue, aside from the price tag, says Breault. However, he says a smaller one could be problematic if the system demands a larger size.

“If your incoming pressure is 80 psi and your relief valve is at 150 psi, you have a difference of 70 psi. A certain amount is going to be absorbed by the plumbing system, the rest is absorbed by the tank. However, if your incoming pressure is 40 psi, now you have 110 psi difference and can get away with a smaller tank.”

A number of expansion tank manufacturers offer online calculators to help contractors determine the appropriate size for a system.

Tanks come advertised with pre-set psi levels, which he suggests are irrelevant. “The pressure of the tank when installed should be matched to the system’s pressure,” says Breault. “Air is compressible, while water really is not. If your house is running on 80 psi and the tank only has 40 psi, when you introduce the tank to the system, it will add water until the pressure in the tank reaches 80 psi. The tank may actually take on more water than it’s suppose to contain, reducing its capacity for expansion.”

Breault recommends adjusting the tank’s air pressure before introducing it to the system. If you skip this step, the air in the tank will be compressed. “It should be done when the tank is voided of water. Every expansion tank has a common schrader valve allowing an air compressor or simple pump to bring the pressure up to match the system.”

As a second tip, Breault suggests hanging a tank downward, vertically at the connection point under the pipe. Some installations feature tanks that are installed inverted or horizontally. “Horizontal tanks introduced to water may trap some air on the water side of the tank, reducing the amount of water in the tank that it’s designed to take. The tank’s bladder may also have a dry patch. When the bladder is fully wet, it stays flexible and is less likely to crack. If you install the tank upside down, that air patch is across the entire bladder, which could affect its overall life.”

In situations where space is limited and an upside-down connection is the only practical option, Breault suggests ensuring the tank is sufficiently supported.

“Upside down, the tank is pushing the piping. If the tank is not 90-degrees up, it could start twisting the pipe, especially on a copper tube. The tank should be supported properly.”

Quiz time F

or this edition of Quattro’s Corner, I decided to change it up a bit. Rather then giving you a photograph of an incorrect installation and providing you with the correct code references, I have given you a photo that meets all requirements of the national and Ontario codes, and a fill-in-the-blanks set of comments pertaining to what’s shown.

I hope this quiz style format gets your brain going and maybe even sees you flipping through your code books. Sometime we need a refresher to keep us up to date on the ever-changing code.

The details in Ontario This picture shows the water closet (W.C.) being wet vented as per the building code. The W.C. is installed downstream of all other fixtures as per code reference (1)_______.

It also meets the maximum allowable change of direction for trap arms of water closets, S-trap standards or any other fixture that discharges vertically and depends on siphonic action for its proper functioning. This direction change is set at a maximum of (2)________, as per code reference (3)______.

Vent pipes that protect water closets or any other fixture that depends on siphonic action for its proper functioning shall be located so that the distance between connections of the fixture drain to the fixture and the vent pipe shall not exceed the vertical limits of (4)_______and horizontal limits of (5)______, as per code reference (6)________.

Catch Quattro Live!

Andrew Quattrociocchi is bringing Quattro’s Corner to CMPX in Toronto. Catch his 2:45 p.m.

“Plumbing - From the eyes of the inspector” session on Thursday, March 22. He will talk about common mistakes, and how these can turn into plumbing mishaps related to sewers, water service, inside drains, rough-ins for stacks, wastes and vents, water distribution, and inspections.

This photo also shows proper support for nominally horizontal piping that is inside a building to prevent swaying, buckling and to control the effects of thrust. The maximum spacing on horizontal 3” ABS is (7)________, as per code reference (8)________.

Looking at requirements for supports, let’s look at the PEX water pipe in the photo. As per code requirement, or Table (9)________, plastic water pipe must me supported at intervals not exceeding (10)_________ on the horizontal.

Enjoying the complexity From modest bungalows to huge custom estates, Woods’ career has afforded him the privilege of working on a broad range of homes, but his favourites are the larger, more complex projects.

“When I first started with the company I was partnered with one of the more experienced technicians,” says Woods. “We ended up working on a 12,000 sq.-ft. home where we installed hydronic heating in the driveway, garage, front patio and steps, and even towel warmers in the washrooms. That sort of custom work involves a lot of hard work, tools and thought.”

graduation. Of those seven, three of Woods’ classmates are still with the company today.

“Our school was known for its HVAC program, so some of AtlasCare’s head technicians came to our college to conduct initial interviews with the students.”

It turns out Woods lucked out. Eleven years later, he has gone on to become one of his company’s go-to technicians with specialization in service support.

“I love this job because it’s all hands-on.”

TOOLS FOR HVAC SERVICING It goes without saying that an HVAC technician is only as good as the tools he uses on the job. While there are staples in every toolkit, there are also a few optional items that could come into play depending on the type of job (residential vs. commercial) and the nature of the work you are doing (installation, maintenance or troubleshooting).

Here’s a list of the top must-haves (or nice-to-haves) for today’s HVAC technician.

A clamp meter, or fork meter, is the number 1 staple item in every HVAC technician’s tool kit. These meters come in all shapes and sizes, and are used for testing the current flow on electrical systems such as compressors, blowers, and motors.

measures air flow coming off the ductwork.

“A lot of HVAC technicians looking at condensers, furnaces

“Typically they are used for general maintenance on site, where you need to measure voltage and amperage on units,” says Sean Silvey, product specialist with Fluke and a former HVAC technician. He adds that meters are becoming increasingly sophisticated in terms of their versatility, measuring capabilities and accuracy.

Both a clamp and fork meter do a similar job in how they gather data. Clamp meters can be put around a cable or wire, leaving your hands free to do your work. A fork meter is used for testing cables attached to walls or in places where a clamp won’t reach. They also come with a wide variety of test probes and leads to make direct contact with circuits where needed.

According to Keith Potts, national trainer for Milwaukee Tool Canada, everybody uses meters differently, but when speaking to technicians in the field these are generally the things they want to know:

or AC coils want to measure how much air is being pushed through, and will use both a hygrometer and anemometer,” says Jeremy Bartel, district sales manager, Central Canada, with Flir. “Testing air flow provides a baseline for a system that you can use later.”

An anemometer is definitely a frontline tool to validate if a unit is working correctly, says Silvey. “A lot of times you get

• The rating: A Cat III (rated for 600 volts) or Cat IV (for 1,000 volts) is the rating you should go for. “Using a Cat III on a 1,000 V line would give you a good showing but a short one.

A Cat IV is a must for working on commercial jobs,” Potts says.

• IP (ingress protection) rating: This two-part rating refers to dust and moisture (6/5 is the highest rating). If working in areas where there is plastering and sanding a 5 or higher rating for dust will protect your meter. “If someone is installing a sprinkler system in a warehouse and fixing leaks, you would need at least a 4 moisture rating, which means it’s water resistant, but not waterproof,” Potts says.

• NIST rating – This certification isn’t always required, but may be demanded in certain industrial settings.

• True RMS – This is more accurate than wave patterns when measuring current as it provides exact numbers at any given moment during testing. Most probes and higher-end units are True RMS.

Combustion Analyzer Co Com A combustion analyser is used to measure re carbon monoxide, carbon dioxide and oxygen levels in boiler and furnace systems, among other gases (e.g. nitrogen dioxide, sulfur dioxide). When the probe is connected to a flue system, it monitors draft pressure and flue temperature as well as air temperature to calculate overall efficiency and to determine if there is any excess air in the flue system. Combustion analysis can be used on a wide range of fuels, including ng natural gas, oil, propane, coal, wood and kerosene.

These are typically used in commissioning g new installations or validating on older systems, Silvey says. “A combustion analyzer is a great way to make sure that your high-efficiency h-efficiency furnace or boilers are working correctly.”

ADVANCEMENT IN METERS As technology evolves and products get smarter, there are a couple of important trends that are helping HVAC technicians work more efficiently.

One is connectivity. With smart homes and the many sensors being installed in commercial sites these days, it’s important to have tools that have the built-in capabilities to take readings and transmit data to a computer or phone, Silvey says.

“Sometimes you don’t even need to go to the roof to test out an HVAC system. You can [remotely] link your computer to a test tool taking measurements to know whether something is working or not. That can also help technicians taking measurements in energized areas work safer.”

This useful troubleshooting tool lets you visually inspect what is going on in areas you can’t access in ductwork and other hardto-reach areas to identify any blockages or fracture cracks. It’s an optical device made up of a flexible tube and camera. Depending on your needs, units come with tubes that can run from one meter up to 30 meters in length.

More advanced borescopes have pivoting cameras that can rotate 180 degrees to look around corners and up and down shafts.

Higher end units also have LED lighting on the end for better illumination. A general rule of thumb in pricing is, the smaller the camera and the higher the resolution, the greater the cost. If moisture is a concern, there are units that are also water and weather proof.

Another is more multi-function tools. For example, there are now meters that integrate a thermal imaging camera, says Bartel.

“That allows you to detect heat patterns that will not show on the electrical testing side. If you’re just checking the electrical status of a piece of equipment, you’re only getting half the story. If you’re using thermal imaging, you’re only getting half the story. It’s a great way to reduce the number of items you need to carry.” Technicians coming out of college are now being trained to work with tools like multimeters that offer multiple functions in one shot, Silvey says.

“Believe me, that tool bag gets heavy pretty quickly. It’s nice to have tools that do multiple things.”

hen Vantage Foods was looking to increase the size and production of its Belleville, Ontario facility, it decided to really up its game on the mechanical end as well, increasing the size of its refrigeration plants to handle the currently expanding needs, as well positioning the company to incorporate any future growth at the site.

In the summer of 2016, Vantage Foods, a supplier of case-ready fresh meat and seafood to some of Canada’s largest food retailers, announced its plan to undertake a large-scale expansion in Ontario, a project that would be taken on by Cimco Refrigeration, RefPlus Refrigeration and the Master Group.

Taking a year to design and plan, equipment started arriving this past September, one transport truck after another. Wayne Sorhaitz, site foreman for Cimco Refrigeration, orchestrated timed deliveries and sequential installations of everything from the racks and condensers, to the evaporators, piping branches, main line headers, and electrical.

Anyone who has experience trying to organize and stage a large-scale project will tell you that it’s no walk in the park, but Wayne and his team, along with the equipment suppliers, helped to ensure that the schedule could move forward without a hitch.

piping IT RIGHT Pipe sizes on the refrigeration system at Vantage’s Belleville facility go up to 4-1/8” on the main headers, which was cause for everyone to be extremely mindful of the type of copper pipe that is allowable in this application.

After careful consideration and calculation, selection of the correct type of copper pipe was made such that it conforms

M e c h a n i c a l

to the CSA B52 Refrigeration code requirements, as well as Ontario’s TSSA conformances.

The question of whether to use Type L or K copper comes up frequently in refrigeration.

Typically, contractors face this issue when dealing with systems that operate at higher pressures, such as air-cooled systems using R-410A refrigerant. These have a minimum high-side design

pressure of 444 psig, according to Table 4 of the CSA B52-05 Mechanical Refrigeration Code.

This requires special attention to the minimum wall thickness selected for the copper tubing.

meets the required minimum wall thickness. Other sources for verification can include handbooks such as those published by the Copper Development Association.

When working with larger pipe sizes, say between 1-1/8” and 4-1/8” pipe, the selected thickness needs to be verified using calculations from the piping code to ensure it

The following calculation can help determine the maximum pressure allowed with a particular diameter of pipe.

THE

The refrigeration project at Vantage incorporates a multitude of systems totaling over 750 hp, which is divided between five parallel rack systems that deliver around 380 net tons of refrigeration to more than 50 rooms that are used for everything from production, preparation and packaging, to blast freezing and holding coolers.

WATCHING THE WORKS Developed for enterprise refrigeration applications that incorporate hundreds of KE2 Therm controllers and sensors, the KE2 Edge Manager technology used at Vantage Foods integrates with other common equipment management platforms, providing RESTful APIs, controller and sensor data logging, enterprise support, Modbus and BACnet industrial protocol gateway services, and realtime dashboards.

While integration with other business systems is especially appealing to technical departments, the dashboarding capability is important to service technicians and facilities managers.

Providing real-time service views, the dashboards offer users secure remote access to control and manage controllers and sensors.

The system will also self-monitor to find when additional controllers and sensors are brought online.

WHERE:

P = allowable pressure, psi

S = maximum allowable stress in tension, psi t = wall thickness (min.), in.

D = outside diameter (max.), in.

Although we don’t see a lot of R410A in refrigeration applications, the same rules apply for all refrigerants, although we mostly deal with R404A, R507A, R448A, R134a,

system

The systems consist of three medium-temperature parallel packs, and a pair of low-temperature parallel packs, each equipped with up to 165 hp of Bitzer two-stage compound compressors on board.

Every evaporator in this project has been outfitted with KE2 evaporator efficiency controls, which allow for very tight control over the system and give technicians a broad range of digital setpoints.

Suction temperatures amongst the units range anywhere between 30°F for medium-temperature circuits, and plummet down to -50°F for the ultra-low temp circuits. Operating on R404A and R507A, these conditions are easily attainable, and will work efficiently throughout the life of the system.

The blast freezers have also been outfitted with Electronic Expansion Valves (EEVs) which will assist in the efficiency of operation, and accommodate for varying load demands.

Targeting optimal performance, the system is also equipped with Emerson E2 Einstein CPC controllers, and a KE2 Edge Manager System that is coupled with integrated building automation controls to allow for a steady stream of system measurements.

R402A and R401A on the lowtemp side of the business.

Sized for now, and later

Be mindful that Type L or K copper is not the only classification you must observe.

Ensure you have a proper rating stamp of ASTM B-280 for Type L or ASTM B-890 for Type K.

What makes the control system special on this project, is that it can be expanded. The controls have been specially designed to allow for growth, so if Vantage decides to add more capacity in the future, or perhaps retrofit some other equipment that is existing, they have the opportunity to do so in a more cost-effective manner, with expansion modules that can accommodate additional sensors throughout the building.

SMALL-FORMAT REFRIGERATION Regulations bring natural refrigerantsâ&#x20AC;&#x2122; viability to the forefront.

O

f all the commercial refrigeration sectors impacted by recent regulatory activities, the small-format retail and foodservice markets have arguably been hit the hardest.

Comprised of small grocers, convenience stores and restaurants, these markets not only use the widest variety of equipment and system architectures, they are also faced with understanding new refrigerant requirements in each equipment class.

The net result is a sea change to refrigeration architectures in these segments â&#x20AC;&#x201D; one where natural refrigerants propane (or R-290) and CO2 (or R-744) play an increasingly vital role.

With so many factors impacting these markets, itâ&#x20AC;&#x2122;s easy to see why thereâ&#x20AC;&#x2122;s an unusually high degree of confusion and uncertainty. Making sense of it all is not easy, but many owner/operators are tasked with selecting the refrigeration platforms that will accomplish their short- and long-term operational objectives.

In recent years, the industry has made tremendous progress in developing equipment that is more environmentally friendly and energy efďŹ cient than their predecessors, but environmental regulations continue to push boundaries, so the transition to equipment that uses refrigerants with lower global warming potential (GWP) is underway for many in this market segment.

ecause of regulatory activity, business operators can expect new equipment options and architectures from OEMs. Itâ&#x20AC;&#x2122;s also becoming more common for retailers and restaurant chains to state sustainability objectives â&#x20AC;&#x201D; from the selection of eco-friendly refrigerants to lowering their overall carbon dioxide equivalency.

In response, many OEMs are selecting refrigerants that offer both lower-GWP levels and performance efďŹ ciencies. Some OEMs are even developing new units in hopes of achieving compliance for future, potentially lower-GWP requirements.

For those taking this â&#x20AC;&#x153;end gameâ&#x20AC;? approach and attempting to clear regulatory hurdles once and for all, natural refrigerants are currently the only options for achieving this objective.

WHAT MAKES THE BTU

[

W

British

hy isn’t there a CTU? You know, a Canadian Thermal Unit? It has a nice homegrown ring to it, doesn’t it? Feel free to adopt it if you’d like, and give it any value you please. You won’t be the first.

The BTU, this thing we can feel but not see, has quite a history. And seeing as the British are supposed to be using the metric system these days, they’re mainly using calories instead of BTUs, so why shouldn’t you be able to rename it to something closer to home? Hey, Thomas Tredgold did. Which brings me to an old friend.

]

THE ORIGIN OF THE UNIT John Woodworth was THE guy I read in trade magazines when I was growing up. I’d write to him with comments and questions about his articles. When I became a writer in magazines we became good friends. When he retired from the Hydronics Institute, he gave me a tattered 1836 text with a broken spine.

The title was Warming and Ventilating of Public Buildings. I slobbered all over that book because I am a student of history. Its author, Thomas Tredgold, the man who gave us the BTU, had published the first edition back in 1824. My gifted copy from John was the Third Edition, and on page 24 I found these delicious words: “In order to compare the effects of different kinds of fuel, some convenient measure of effect should be adopted: not only for the purpose of lessening the

98

M e c h a n i c a l

B u s i n e s s

trouble of calculation, but also to render it more clear and intelligible. I shall, therefore, without regarding the measures of effect employed by others, adopt one of my own, which I have found useful in this and other inquiries of a similar nature. I take as the measure of the effect of a fuel, the quantity, in pounds avoirdupois, which will raise the temperature of a cubic foot of water one degree of Fahrenheit’s scale.”

Thomas Tredgold was a railroad engineer who dabbled in heating buildings. Steam Thomas Tredgold locomotives had been in England for just 20 years when Mr. T first published his book, and there were some steam-boiler explosions that the early adopters had to deal with.

Well, actually there were a lot of steam-boiler explosions that

0 4 . 1 8

HEATING they had to deal with, so Mr. T figured it would be good to have a better way of measuring heat energy. And so arrived the British thermal unit.

Of course, he said that his new unit of measurement would be the amount of heat it took to raise one cubic foot of water one degree Fahrenheit. Not one pound of water, as it is today.

So why the change?

In the book, he gives examples of how much fuel it would take to bring a cubic foot of water to a boil from several different temperatures. He explained about latent heat, and how we have to add a lot of that to get water excited enough that it changes from liquid at 212°F to steam at that same temperature on Gabriel Fahrenheit’s scale. He covers all the bases, and in a delightfully British way.

But I keep smiling about that change from one cubic foot of water to one pound of water in the definition.

I’ve never been able to track down the exact answer, so I speculate. I figure the term got changed for one reason and one reason only: Mr. T had assumed ambient temperature on the Fahrenheit scale. And once he was gone, all bets were off.

ALL IN

favour?

The original BTU came out of one guy’s

imagination. The British thermal unit could have been anything. What mattered was that enough people got on board and agreed to use his term and not someone else’s.

When you think about it, all the terms we use for measurement came to be in a similar way. What makes a metre a metre, or a gram a gram? How about a kilometre and a mile? The movement from English units to metric units didn’t change anything other than the way most folks decide to measure things.

Be an Imagineer Years ago, I wrote a book called Pumping Away. I ended it by trying to convince my reader to be an “Imagineer.” At the time, I had no idea that Disney was using that noun to describe their creative people. I just loved the sound of the word.

I encouraged my reader to think about the colour and the weight and the texture of a British thermal unit and other things that we can’t see but we can feel. I wanted my reader to be able to do this because there will be days when he or she will have to explain this invisible thing to people who know nothing about heating, but who might buy something if the Imagineer can make

the potential customer see what’s going on.

Units of measurement are nothing more than nods of agreement. There is nothing sacred about the British thermal unit. If you choose to call it the Canadian thermal unit it will still heat your home.

Thomas Tredgold figured he could get away with naming his new unit of heat after his beloved

Light a match, I said in my book. Let it burn until it reaches the very tip of your finger.

The customer will watch, sitting on the edge of her seat. “That’s a single Btu,” you will say. “When your burner comes on, it will be like 7,500 books of matches, all flaring up at the same instant. Imagine that power!”

country.

So, I hope this may inspire you to start a pseudoscientific movement. All you have to do is make up a new name for something and gather a group of fellow believers around you. Find agreement and you, too, will be famous.

Imagineers paint word pictures and people love word pictures.

Ks Ms

Speaking of making things up, how about those letters K and M that wind up in BTU ratings? I’ve seen those two confuse a lot of tradespeople.

Here’s the story: The K in KBTU means 1,000, and it represents how many BTUs you need per square foot of conditioned floor area.

But then we switch over to MBTU and MMBTU when we’re talking about natural gas. The M goes back to the Romans and their numerals. It means 1,000, not one million, but if you see two Ms used together (MMBTU) that means one million (a thousand thousand), even though, to the Romans, MM means two thousand.

Why do engineers do things this way?

Trade shows: Should you attend? Can you afford not to?

E

very second March, on the even-numbered years on the calendar, I always get a spark of excitement. That’s when the CMPX show comes to Toronto, and I get to be like a kid in an arcade.

Roger Grochmal is the CEO of AtlasCare in Oakville, Ont. To submit a question about your company, business practices, or the industry in general, send an e-mail to Mechanical Business Magazine’s editor, Adam Freill, adam.freill@ mechanicalbusiness.com.

After 45 years in the HVAC industry, and attending countless shows across our continent and beyond, this is still my favourite show.

I like the fact that it’s the right size to connect with a lot of people in a quality way, and that it takes place every two years instead of annually. Enough change occurs over that period to keep the show interesting and relevant.

Every time the show comes around I get asked if I will be attending and the answer is always a resounding YES!

Being Prepared

By nature, I am a curious person. I never drive home the same way two days in a row, because I want to see what’s new in the neighbourhood, and HVAC is my business neighbourhood.

I never attend CMPX without a pile of business cards – and yes, they are still relevant! Shows like this one often have factory representatives and corporate executives in attendance. This gives you get an opportunity to build deeper relationships with suppliers that reach beyond your local sales representative.

I go to see what has changed. And every show contains a lot of change. Not only that, but the pace of change is certainly accelerating, and for that reason I can’t imagine missing a cycle of this important show.

WHERE THE PROS GO TO CHAT We are all professionals, and CMPX is where all the professionals in Canada come together.

I’m sure that, technically, we could learn a lot of what we need for our business from other sources. Trade publications help keep us informed, as do industry and supplier websites and social media, and shows are useful from that point of view, but they offer a bit more than these self-directed learning platforms.

In my experience, what trade shows in general, and CMPX in particular, do is bring everyone together.

I may be old-fashioned but I enjoy getting face-to-face with people to see their reactions to the questions I ask, and to have a truly engaging discussion with them that you can’t get over email or a phone call.

These interactions help me to better understand people, build personal networks and pave the way for future conversations. I also find a lot of old faces in new roles in different companies.

Trade shows: Should you attend? Can you afford not to? with Roger Grochmal A TEAM EFFORT TO FIND CHANGE

CHANGE IS AFOOT

This show is suitable for almost everyone who works in our industry. At my company, we encourage as many of our staff members as possible to attend the show and bring back an idea.

Personally, I like to walk the corners of the show and check out the small booths. I often find that some of the best ideas come from new companies that are just dipping their toes into exhibiting â&#x20AC;&#x201C; hence the small booth. After every show, we implement something new in our business.

Sometimes it is something small, like a new accessory or tool to improve productivity; other years itâ&#x20AC;&#x2122;s a more significant change.

At the last show, we identified two new initiatives that are transforming our business. We made the decision to join the Nexstar network, and we are well on the way toward implementing their business model and processes. And, we identified an exciting new business software platform that we will take live right after the show.

Neither of these initiatives were on our radar screen going into the show, and both are transformative for their impact on our business.

I will be at the show for all three days, and I plan to attend at least one seminar. You might bump into me in the corners checking out the small booths but if you would like to corner me with a comment or a question, I can be found working in the Nexstar booth (1930). Please pop over. Say hello. Start a conversation. Itâ&#x20AC;&#x2122;s why we go, after all.

Our industry has seen seismic change over the past few years.

Company consolidations, acquisitions and new distribution arrangements abound. This means there are many new people to get to know and interact with just to continue doing business.

Suppliers are coming out with new products, and a show like CMPX is a great opportunity to see them up close and learn more about them.

New technologies that make use of the Internet of Things (IOT), webbased controls, and software and apps to improve our businesses are coming out everywhere. Spending a few days at the show can save me a lot of time learning about whatâ&#x20AC;&#x2122;s trending.

See you at the show!

COMFORT SUCCESS WITH

L

ast summer I spent an inordinate amount of time in Florida and South Carolina helping builders and mechanical contractors with high indoor humidity problems.

Of course, winter, not summer, is the right time of year for a middle-aged Canadian to be in Florida, and it is usually in winter that I am diagnosing indoor humidity problems in Canada. However, there have been important changes in houses in Florida that are impacting indoor moisture control the summer months, and we should take note to avoid similar problems here in Canada.

As you make your way into this year’s air conditioning season, it is best to be mindful that true comfort comes from addressing both temperature and humidity.

Educate the consumer Speaking with homeowners about the two separate functions of their AC systems – lowering temperatures and lower humidity – may help you lead into other opportunities, such as switching to an energy recovery ventilation system, and ultimately to a whole-house dehumidification system.

To put a fine point on those last two items. If a household is currently ventilating with an HRV or a simple exhaust-only ventilation system, installing an ERV would reduce moisture loads by 10 to 15 litres a day on the highest humidity days at very low power consumption.

A whole house dehumidifier can remove in the order of 40 litres of moisture from the air each day, at a very efficient three litres per kWh of operation.

Gord Cooke

M e c h a n i c a l

The difference between a nice comfortable 23°C, 50% RH indoor condition and a muggy 65% RH is just an extra three to four litres of water dispersed into the air of a typical 2,300 sq.-ft., two-storey home.

And a properly sized AC system with correctly adjusted airflows and refrigerant flows needs to operate for at least 15 minutes, and as long as 30 minutes, before any moisture will drip off the coil and down the drain line.

Of course, if the fan is left on during the off-cycle, the moisture left on the coil will be re-evaporated into the air in about 30 minutes.

HIGH-PERFORMANCE HVAC

AC LOADS HAVE CHANGED Newer homes typically have more and bigger windows than older homes, so now 40 to 60 per cent of the AC loads experienced are associated with the heat gain through windows.

DEFINING THE TARGETS An optimized system should be able to remove about 1.5 litres of water per hour, per ton of AC capacity. You could, quite literally, turn on the system on a hot humid day, wait a half-hour for the condensate to start flowing, and measure the amount produced over the next hour. A three-ton system should nearly fill a fivelitre pail.

This results in a high peak, but intermittent sensible load, which is what we use to size the capacity of the system. However, the base latent or humidity load is fairly uniform throughout the day and night (unless the occupancy loads vary greatly throughout the day).

If you aren’t getting proper moisture removal it would be an opportunity to adjust the airflow over the indoor coil. This typically means lowering the air handler fan speed to lower the supply plenum temperature, without compromising the overall operation of the system.

Let me reiterate that; we size for a peak sensible load, but a significant element of comfort success and risk management is based on a fairly uniform base latent load.

We want to meet the expectations of our clients for a reasonable response time during hot, sunny periods, but there are pitfalls with respect to proper moisture control when oversizing AC systems. Fortunately, there are measures and opportunities for success in achieving a comfort balance.

VARIANCE AMONG THE Es

Low E coatings on windows became a code requirement for new homes in Ontario in 2009, and energy efficiency programs across the country have encouraged Energy Star windows with Low E coatings since the mid-2000s.

It’s best to refer to the AC manufacturer’s pressure/temperature charts and measure the suction line pressure, but a quick check can be done by measuring the dewpoint temperature of the air in the supply plenum or, easier yet, at the first supply register.

If you are trying to achieve an indoor condition of 23°C and 50% RH, the dewpoint temperature of that air is 12°C, so your target for the supply air should be two or three degrees below this.

Turn the system on, let it run for around 20 minutes, and measure the dewpoint temperature of the air at the supply register nearest the air handler. If it is not approximately 10°C, then turn down the fan speed until it gets there. After adjusting the flow, be sure to check the manufacturer’s specifications to be sure the system is in an approved operating range.

HUMIDITY

Low E coatings vary significantly by manufacturer, however, so it is possible to meet Energy Star requirements with coatings that result in a solar heat gain of anywhere between 0.2 and 0.6. That is a threefold variation in solar gain through the window.

It is possible to purchase a simple detector that when placed on a piece of glass will indicate the solar gain characteristics of the window.

CONTROL OPTIONS Lowering the supply airflow may not be desirable during all operating periods.

Fortunately, many new thermostat controls and AC systems allow for a “humidity” cycle.

For peak cooling times, the system runs at full airflow, but when the thermostat is satisfied for temperature and the RH is higher than desired, the system would come on at that optimized (lower) airflow rate to more effectively dehumidify the space.

Alternatively, at very low cost you could adjust the thermostat setpoint dead ban zones so you get longer run times. By switching to Fan Auto mode, or setting the fan operation to turn off for 15 minutes after an AC cycle, the evaporator coil can drain and not re-entrain the moisture back into the air stream.

DETECTING

Refrigerant Leaks COMMON REFRIGERANT LEAK DETECTION TOOLS • Electronic Leak Detectors (heated diode type) – This is one of the most used tools for detecting refrigerant leaks. Accuracy is dependent on the make/model of the detector and ensuring that it is used properly. Annual calibration is required to ensure accuracy.

• Soap Bubbles – These are easy to use when looking to get a visual indication of refrigerant leaks.

They are very accurate, but can have limitations in tight spaces.

• Fluorescent Dye – This is another visual method of detecting leaks. It works with nearly all refrigerants, and requires that dye be added to a refrigerant-based system. A bright UV light and UV glasses are also required with this method of leak detection.

W

e are all aware of the environmental impact of ozone-depleting refrigerants being released

into the atmosphere. And now, more than ever before, such concerns are top of mind, especially since the United Nations and all 197 signatories to the Montreal Protocol reached a legally binding commitment to limit global HFC use globally.

The deal promises to phase out the use of HFCs and replace them with more environmentally friendly refrigerants. But the replacement of HFCs, and other legacy fluorocarbon-based refrigerants, is a gradual process and it can take years for systems to be updated.

As such, refrigerant leaks should remain a concern for HVAC/R contractors everywhere, and systems should be checked regularly for leaks. Here are some

tips on how to isolate them.

M e c h a n i c a l

TIPS ON USING ELECTRONIC LEAK DETECTORS 1. Before you get started, do a visual inspection of piping and components. Be sure to check carefully for any damage, corrosion or oil stains.

2. Next, confirm that the leak detector’s sensor has not exceeded its usage period.

3. Turn on the detector, with the pump on and drawing air. Make sure you get a zero reading before proceeding.

4. Move the detector’s probe sensor within approximately a quarter-inch of the suspected leak area. Use a slow, circular motion as you move the sensor along the pipe surface.

5. Leaking refrigerant will be drawn into the unit by a small pump, which will then activate an LED and an audible alarm.

6. In some cases, there may be high concentrations of refrigerant if you’re dealing with a large leak.

To better locate the source of these leaks, set the sensitivity on your device to low and repeat Step 4.

FREE COOLING FOR COLD CLIMATE

PART-LOAD MOST OF THE TIME

centres

O

perational costs are a substantial consideration for all building owners. For data centre owners, that consideration is even more pertinent as the cost of energy is most often the largest operating cost in these mission-critical facilities. As such, cooling energy cost is likely the biggest operating expense (OPEX) cost reduction and mitigation opportunity.

Direct Outdoor Air (DOA) free cooling uses cooler external air supplied directly into the data centre Information Technology Equipment (ITE) space as the primary means of cooling, and is an economical and energy efficient process to find energy savings.

Maximizing the use of DOA free cooling, coupled with other effective, energy efficient best practices, can yield substantial energy savings.

A design based on industry leading air handlers that provide high partial load efficiencies matching typical actual data centre loads – generally 25 to 85 per cent of rated full-load capacity – can deliver substantial savings when implemented with cold-aisle/hot-aisle separation, closer cooling coupling the air handlers to cold-aisle/ hot-aisle spaces.

In the data centre environment, high uptime is often expected, and may even be a requirement for some types of facilities.

Typical best practice is to design redundancy (N+1, 2N) requiring system and DX or CW (Chiller) mechanical equipment capacity size selection to be based on ASHRAE-set 50-year extreme temperature and humidity conditions.

Since actual data centres operate partially loaded, and because the DX or CW (chiller) equipment will be required to provide supplemental cooling where the DX/ Chiller will be partially, often lightly loaded, care must be taken to select DX/Chiller equipment having superior IPLV, turndown, re-start/start and ride-through capabilities.

TARGETING MISSIONAir handlers are at the core of some of the most effective free cooling design strategies.

Designing an air handling solution that incorporates an ECM fan array offers redundancy, variable flow and higher efficiency for mission-critical applications.

With options to configure for N+1, N+2, 2N, etc. fans, the latest fan array technology can provide operational backup when it’s needed.

More specifically to the operation of data centre space, supply air directly floods the cold-aisle space and return air is directly pulled from the hot aisle spaces (closer coupled cooling).

Typical practice is to have contained hotaisles and contiguous flooded cold-aisle spaces where the larger shared cold air capacity provides ride-through supply air

TEMPERATURE AND RELIABILITY The latest ASHRAE TC9.9 Thermal Guidelines (4th edition) describes temperature versus reliability X-factor economization optimization. TC9.9 has established a baseline failure rate, defined as 1.0, representing ITE mean time to failure (MTTF) operating constantly at 68°F (20°C) for 24 x 7 x 365 operation over multiple years.

The ITE failure rate impact of operating at different temperatures can be understood by considering a hypothetical example of a 100-rack, 42-RU, 80 per cent filled data centre containing 1,680 servers. The typical server failure rate is 3.5 per cent per year (2.5% on the low side, 4% high) so when operating constantly at 68°F (22.5°C) baseline for one year, 59 servers are expected to fail. When operating at 63.5°F (17.5°C) constantly for one year, ITE failure rate becomes three per cent, so 51 servers are expected to fail (nine less than at 68°F). At 77°F (25°C) 73 servers are expected to fail (4.3%).

BEST PRACTICES FOR SUCCESS BEGIN WITH GOOD DESIGN

Without proper flow through the unit – roughly 1.5 to two gpm/t on open loops and three gpm/t on closed loops – the refrigerant will not properly transfer heat to and from the loop.

T

he most important part of any geothermal installation is the design of the system, beginning with an accurate load calculation. This requires a room-by-room calculation for zoned systems and a block load calculation for non-zoned systems.

Each piece of equipment has its own flow characteristics, and each property has specific ground conditions that need to be considered. Fortunately, manufacturers offer software designed with distinct knowledge of their equipment’s operation and requirements. A loop design based on an industry-respected and manufacturerbacked program should be part of every job.

It’s also a good idea to conduct a whole house blower door test.

Measuring how tightly a house is sealed will speak to the accuracy of the load calculation. It will also help determine if adding insulation and air sealing can increase comfort and reduce equipment size.

Equipment selection is based upon the Manual J calculation and the Manual S. In addition, most manufacturers offer an equipment selection program. During the selection process, it is important to review the bin data chart of the designed system to confirm proper sizing.

The load calculation will also impact critical loop design and flow centre selection. If the loop is too long, the cost of the installation will increase. If it is too short, the system will lose capacity and efficiency, resulting in uncomfortably high temperatures in the summer and low temperatures in the winter.

120

M e c h a n i c a l

For flow centre selection, it is important to include the loop termination inside the home and flow centre location in relation to the equipment during the pressure drop. Design for the smallest flow centre that will deliver the required flow, and remember, small loop configuration changes can reduce flow centre requirements.

Don’t overlook duct design when designing a geothermal system. In retrofit situations, it is imperative that whoever performs the Manual J measures the ducts and confirms they are sized for proper airflow. If they are not, duct alterations should be included in the bid.

This should not be an issue with new construction, but again, confirm that proper duct sizes have been specified based on the appropriate manual.

GEOTHERMAL START-UP PROCEDURES IMPACT OPERATION During construction, it is important that geothermal equipment not be used until construction is complete. Dirt can enter the unit, and the loop can be over stressed by the drastically larger load. As a result, the system may not work properly when the homeowner moves in.

When it is time to start the system, never put gauges on it. Whether on water-source or air-source equipment, attaching gauges can remove refrigerant. On a package system with a critical pre-installed charge, it does not take much to create a low charge condition.

If a problem is encountered with a system, rule out waterside, airside and electrical issues to see if they lead to a possible

Until they do, resist the temptation to install a gauge. After a system has been properly charged, it should never require gauges.

During start-up, remember to confirm the airflow, sequence of operations, water flow, heat of extraction (HE), heat of rejection (HR), heating content (HC), sensible BTUs in cooling (SC), electrical connections and system settings. The installer should never expect settings to be 100 per cent accurate for the application, but every setting should be checked on new installations.

MODERN BENEFITS OF VARIABLE SPEED

PREVENTIVE MAINTENANCE ENSURES LONG LIFE Like other HVAC systems, geothermal systems require maintenance. However, the maintenance is not as extensive because the system does not include outdoor equipment.

Kits that monitor operations on newer equipment make maintenance easier. Some equipment includes control packages that offer two-way communication between components, along with advanced operating logic and robust troubleshooting capabilities.

Energy monitoring is possible, along with extended hot water generation control and integration with a zoning system. In addition, a special module can extend communication protocols to include the internet and smart grids, making it easy to operate, control and troubleshoot the system.

Troubleshooting is made even easier with the aid of a tool that enables servicing and diagnosing a unit without having to open it.

Onsite preventive maintenance should include the changing of filters, regular cleaning of the equipment, and a check of the HE/HR, HC/SC and water pressures. The desuperheater should also be cleaned and flushed so that it can last as long as the equipment.

The advent of variable speed geothermal technology has further improved system efficiencies across all ranges of operation. This newer option varies air flow, water flow and compressor stages, some down to 20 per cent, matching equipment capacity to load at all times.

Advanced systems offer an extended cooling range to cover larger loads when, for example, a customer is having a party.

With a 60 per cent latent capacity, dehumidification modes can easily remove humidity, and the equipment can serve zones as small as 15 per cent of an entire home without requiring dump zones or a bypass. The zoning systems deliver BTUs rather than just opening and closing dampers.

AIR ADMITTANCE VALVES, THE CODE, A AND HOW THEY WORK

lthough they are often referred to as cheater vents, Air Admittance Valves (AAVs) are not the same as a cheater vent, and AAVs are legit in certain installations – they even

have a reference standard in the National Plumbing Code (NPC).

The primary difference between a certified AAV and a cheater vent is that AAVs have no springs that can lose tension, jam or break over time.

The International Plumbing Code recognizes spring

loaded cheater vents as mechanical devices, but a certified AAV is not mechanical in nature. Rather, the sealing membrane opens by the negative pressure created when fixtures discharge; they close by gravity once the system is back to equal pressure. If there’s any positive pressure in the system, it seals even tighter.

Simply put, an air admittance valve is a oneway device that allows air into a DWV system while preventing sewer gases from entering the indoor space.

Permitted uses and conundrums In the national code, AAVs are permitted to vent fixtures in island counters. In fact, when it comes to new construction, this is the only permitted use for AAVs in Saskatchewan. All provinces but Ontario permit the substitution of costly loop venting with an AAV. The NPC also allows for AAVs to vent fixtures that could be affected by frost closure of the vent, just don’t do that in Ontario, which does not allow that under its plumbing code.

An inspector may find it hard to apply code on a job where an AAV is installed in an attic cavity or outdoors, however, since the national code states that these valves shall not be installed in locations that may experience freezing temperatures, but allows them on fixtures that may be affected by frost closure. Furthermore, the need to be “not less than 150 mm above insulation materials” presumably puts them above insulation in a freezing cold attic. As such, it’s best to check with your local inspector to gain their interpretation of the code prior to installation.

AAVs have their legitimate place in modern plumbing systems.

They provide an alternate means of venting and work well, provided they are installed correctly and the drain lines are sized and sloped properly. However, it is important to install only ASSE-certified valves.

And keep in mind that there are some differences between the NPC, provincial and local codes, which highlights the need for code harmonization in Canada.

Did you know?

Surprisingly, the standard for AAVs was not written by CSA. Rather, the American Society of Sanitary Engineers wrote the ASSE 1051-2009 standard for individual and branch type air admittance valves for sanitary drainage systems. So, it is the ASSE symbol that you should look for on approved valves.

Know the

BASICS OF VENTING Did you know? k ?

In order for the sealing membrane to operate by gravity, AAVs must be installed within 15 degrees of true vertical. Do not install them horizontally or at an angle.

A vent system is an assembly of pipes and fittings that connect the drainage system with p air for circulation and the protection of traps seals. The vent system manages both open negative and positiv positive pressures.

Properly sized horiz horizontal drains accommodate for discharge to fill up to half the pipe diameter. Volume over o 50 per cent of the pipe diameter inhibits air circulation and, in turn, the smooth flo flow of air and waste through the system.

If the horizontal drain dr fills more than 50 per cent due to waste volume, partial blockages, pipe bellying or bac back grading, a positive pressure is likely to occur behind the leading edge of the discharge discharg flow. This positive pressure will seal the AAV, cause the fixture to drain slowly, and may m cause the trap to siphon as the fixture finishes its discharge.

In these instances, a traditionally vented system is able to equalize the positive pressure by exhausting upwa upward through the stack vent to open air. An AAV will not.

As such, it is impor important that drain lines are sized and sloped according to code to prevent the buildup of posi positive pressure, especially in an AAV-vented application.

If you are experienc experiencing slow drain down times in an AAV-vented application, first check to see if the AAV is functional.

To test, clean the AAV A and blow through at the threaded end as if blowing through a straw. The AAV sho should not allow air to bypass. Then, suck through the AAV as if sucking on a straw. The AAV should allow air to flow.

In general, the more drywall and finishing that needs to be torn out to tie into existing venting, the more likely an inspector will cut you some slack and allow an AAV.

M e c h a n i c a l

There have been in instances when weekend warriors have installed AAVs and in doing so allowed ABS cement cemen to run from the threaded adapter, fixing the AAV in an open or closed position. Always Alw cement the adapter in place first and then hand tight the AAV after test at finish. And A always use Teflon tape on the threads. Do not use pipe dope.

In the case of a partial part blockage (i.e. pipe narrowing due to grease build up) an AAVvented fixture will actually show signs of slow drainage in advance of a traditionally vented system, enab enabling the user to address the issue in a timely fashion.

Did you know?

Individual and branch type AAVs are not to be used on acid waste systems, nor exposed to corrosive fumes.

An acid waste version of this type of valve, certified to ASSE-1049, is available, however.

COLD HARD FACTS AAVs were invented in 1973 by Sture Ericson in Sweden.

He installed his invention outside the building envelope in sub-zero temperatures to prevent troublesome frost closures that occurred to his stack vent. Certified AAVs are tested from 65 to o -40°C, in accordance with the ASSE 1051 standard.

PROJECT PROFILE

plumbing until the cows come home

By Adam Freill

D

airy barns use a lot of water. From providing the livestock the hydration they need, to cleaning the milking machines and calf feeders, to flushing dirt and waste, the water demand is considerable. When Nurseland Farms, in Ontario’s Prince Edward County, was looking to build a new structure for its herd, it turned to Steve Veenstra, who had just recently opened S.V. Plumbing.

“I think my biggest challenge was taking on a job that should have taken about four guys and three months to do. I did it all by myself,” said the company owner as he took us on a tour of the barn. “That was the fun part.”

With a need to get everything up and running before the first cows were scheduled to arrive, he put in a lot of overtime hours as the project neared completion. “We worked a good 36 hours in the final three days getting that ready. It was really unbelievable.”

Being a new company, and a one-man shop at the time, he was able to lean on the help of some good friends to help him through some of the project, however.

“I had buddies come help me at night sometimes, and help me dig the trenches. All the underground piping was pretty much dug with a shovel, except for the mains in the barn,” he recalled, adding, “We have about seven shovels now, and I don’t touch a single one of them,” with a good laugh.

His company now has five employees on the plumbing side, and another three in an HVAC division.

“We service a lot of farms,” he said. “I’d love to go all over Ontario doing dairy barns. It’s fun. I do enjoy it. And my guys are like that too. They all grew up around here, and there are still a few farms in my family, so the guys are used to going to these sites to ensure that they have water.”

Dairy farms, he explained, are a different level of customer, since the livestock is reliant on the farmer being able to provide all the necessities of life.

“Homeowners may think they have an emergency at 3 o’clock in the morning, but the only ones we really move for is a farmer because they need water,” said Veenstra. “A homeowner can do without water in the middle of the night, but if a dairy farmer calls because he’s without water in the barn, well, you just go.”

A TECHNICALLY ADVANCED

barn T

he new barn that Nurseland Farms had constructed just outside of Belleville, is a 40,000 sq.-ft. facility that houses 180 cattle.

A modern facility, it uses automated systems to help feed the animals, and robots to milk the cows and keep the barn clear of waste, all of which have a need of plumbing, as does its office space and washroom.

“We did all the plumbing, for the livestock, the milk house, all the wastewater and the supply water for the entire building, with the exception of the manure system,” said Veenstra.

“The drainage requirements for the two robot rooms was 8” drains, half-way down the barn, that go down to the manure pit, and we piped all of that,” he explained. “There is a 5,000-gallon holding tank. That’s a full trickle system, so there’s always 5,000 gallons of reserve for the barn, so they are guaranteed to never run out of water.”

“There’s definitely some things in there that would make an engineer scratch their head,” laughed the plumber, “but it was done because that’s what the owner wanted. He wanted it functional, but easy to fix if it breaks down.”

The system uses a one-horsepower, 20 gpm pump to feed the water system, and the water is drawn from the property, rather than a municipal service.

As such, additional valves were piped in so that the owner could isolate and flush drain lines as necessary.

Targeting water quality, the plumbing system includes a water softener, a pair of 18 gpm ultraviolet lights, and 20” x 4” fivemicron filters to catch big particles.

B u s i n e s s

“There are a few unconventional things in the barn, but they work, and they make sense – adding 3/4” PEX to each 8” 45 so that we can flush them out – stuff like that,” said Veenstra. “We looked at the 45s and said, they could plug up, so let’s drill holes in them and put 3/4” PEX in them, and run them to a T and a big ball valve, and then he can flush them out.”

“He is drawing water out of a swampy area, so it is really gassy and full of algae, so that was the reason for most of that equipment, especially the water softener, since the water was quite hard,” said Veenstra.

M e c h a n i c a l

The owner and operator of the barn had a few special requests, which Veenstra worked into the plumbing system.

Inside the barn, there’s a 50-gallon propane power-vented water heater that handles the domestic hot water needs in the building. For sanitary reasons, it is kept at a piping hot 165°F.

On the domestic side, there’s a bathroom and four hand sinks. On the barn side, there are five stainless steel water tip troughs and four calf feeders, and the robots are also plumbed in, since they need water to wash themselves down between milkings.

IoT

BUSINESS OPPORTUNITIES

The Internet of Things (IoT) is shaping the future of HVAC systems in residential and commercial settings as connected devices work together in an ongoing quest to deliver efficient comfort.

There are many ways contractors can leverage IoT to grow their businesses and spend their time more efficiently. We spoke to Sudhi Sinha, the vice-president of product development at Johnson Controls, to learn more.

Q: How has technology evolved to make the installation and commissioning of HVAC equipment easier for contractors?

A: Advancements in technology have allowed for the creation of easily configured and connected systems by using standardized data models in equipment and devices, embedded computing and processing capabilities in edge devices, and by leveraging cloud technologies.

Building automation systems and programmable control platforms are perfect examples of how these technologies are being implemented in real life. Some leading systems come pre-configured with all the relevant data and algorithms. You can install the system from your mobile device with minimal training and a few clicks. The same technology allows you to use your mobile device to view and analyze data and take appropriate actions.

Q: How are fully communicating smart systems helping contractors diagnose problems and perform preventative maintenance?

A: By embedding edge analytics into smart communicating systems and leveraging cloud technologies to drive more advanced analytics, it enables contractors to diagnose problems and perform preventative maintenance.

The smart equipment systems stems p in today’s leading rooftop units and connected chillers are prime examples of applying such technologies.

These systems can collect and analyze large amounts of operational performancee data from equipment so ntify users can proactively identify es and performance inefficiencies es. future maintenance issues.

134

M e c h a n i c a l

Q: How is IoT helping buildings maximize energy efficiency and achieve full system harmony?

A: IoT allows for more sensors in buildings, the ability to collect and process humongous amounts of data quickly and inexpensively, and it provides access to advanced analytics that are performed using cloud technologies. This has allowed for more targeted identification of issues with energy efficiency in building systems and equipment.

It also has the capability to do model predictive controls, which allows for systems to automatically regulate set points and other operating parameters to optimize cost and energy consumption.

Q: What’s next for IoT? How do you see smart systems shaping building operations in the future?

A: IoT will continue to transform and influence how buildings operate. We will see more applications of reinforced learning that will bring better optimization using artificial intelligence with some humans in the loop.

Low Power Wireless Area Network (LPWAN) technologies will allow for more edge devices to be connected, reducing the dependency on intermediate controllers and gateway devices.

IoT technologies will continue to provide greater personalization and adaptability within the built environment, enabling greater productivity for occupants.

CELEBRITY ENCOUNTER

By Adam Freill

Hitting the ice Ron fondly recalls hiss first steps on a rink, steps that would start his hockey odyssey.

“Hockey requires teamwork. To me it is the ultimate expression of goodwill.”

“My father was in thee Air Force, so we were stationed in Whitehorse, Yukon, in 1964. We lived ived in a little dwelling called a Steelox. It was so cold ld iin th the winter i t th thatt you could see frost heaves where the bolts were on the walls in the inside of the home,” he reflected.

“Across the street, the Clemente family built a backyard rink. They invited me over.”

So, like for so many Canadians, on went a pair of bob skates and, with a chair for balance, he took his first strides.

“What I actually remember from that first skate was chewing balsam sap as a chewing gum after skating – or trying to skate,” he laughs.

“It didn’t take long to get better. We had good long winters in the Yukon, and ample opportunity to get on outdoor ice, and I just fell in love with the game.”

T

he local rink is a revered space for many Canadians. It’s where we gather to build personal character as we play our national sport as kids, and cheer on our hometown heroes as we get older, and it’s where you’ll find Ron MacLean every Sunday during the NHL season as host of Rogers Hometown Hockey.

Courtesy of Rogers Hometown Hockey

“We show up with a little bit of our own story to tell, and connections to the NHL and Hockey Night in Canada,” said the 57-year-old broadcaster during an exclusive interview from his home in Oakville, Ont. “When we get there, we get bombarded with local lore and legend about the game. It’s just really rewarding.”

136

Still playing twice a week at his local rinks, Ron loves the way that dressing room comradery can bring out the best in a group.

“It strips the community of all rank and order. It brings us together and allows us to each be like the other, and to think about the other, and work with the other,” he says. “Hockey requires teamwork. To me it is the ultimate expression of goodwill. You definitely see it in a rink.”

Trading to stripes Although he grew up playing hockey, he traded his stick for referee’s stripes when he landed a radio job in high school.

“I had been cut by the Red Deer Rustlers Jr. A franchise, and had the option to play juvenile, but we didn’t wear masks in those years. I was really worried that I would get a stick in the mouth,” he says.

Concern that dental work could affect his ability to have clear delivery on the microphone, one of his friends suggested that he try his hand at being an on-ice official.

“I had a friend who was refereeing who said, ‘Ron, rather than play, you should try reffing. It’s a way to stay in the game, and it is a safer way for you, now that you are starting your radio career,’” he explained. “I went out and it was like a hurricane. I couldn’t believe how confusing it was the first time I refereed, but it doesn’t take long. Before you know it, it is just fantastic.”

Experience helped with that comfort zone, but he credits an early boss and mentor, Wayne Barry, with giving him advice that helped him, both on and off the ice.

“He explained to me if you let the guest be the star, you will be the star,” says Ron. “That was the greatest lesson, and I approached refereeing the same way. You want your interviewee, or the player, to hit the high note. By taking that quiet, background role, you can make it happen. It was really a perfect parallel for a young radio announcer.”

Finding his calm, at game speed Although it was not a topic that was openly discussed early in his career, Ron admits that he battled a lot of anxiety when he first hit the airwaves.

Working as a referee became an available escape from the nerves he would feel in front of an audience, however.

Exploring microcosms of courage IIn addition n to bein be ing g on o e of the mo ost rec e og og ognized p rson pe on nal a ittie iess in Can anad adia ian broadccas asti ting, Ro R n is also a be bestse ellllin ing in g author, penn au nnin i g a pa p ir of bookks, incclu cluding Hock key To owns: Untolld Sttories from the he He ear a t of Canad ada,, with wi t co-author th or Kiirrst stie McLe Mc L llan Dayy.

We alll co onne nn nect ect to the he e game, e, but it sh howss a wh whole e diff fffer ere ent side to th the ga gam me.” me ”

THE PRINCE OF PUNS Anyone who has watched Coach’s Corner knows that Ron uses humour as a defense mechanism, is self-deprecating, and is quick with a pun and a bit of wordplay – sometimes to the chagrin of co-host Don Cherry.

“I can think of many times when Don has been in a lather, and a little bit more wound than he ought to be; at the end when I do a pun he’s normally right back down and laughing as well.”

“I used to suffer from severe anxiety, from the time I was about 18 to maybe 30, I would get the butterflies,” he shared. “I would fight my way through that – none of us knew or thought about mental illness then, and certainly would never confide that we were weak – but I never had that on the ice.

“It was always a really comfortable place for me. The safest place that I could be was on the ice. I never felt anxiety refereeing.”

And while he cannot say definitively why he was so comfortable at the rink, he does have a theory.

“Because there is so much movement happening, and you are reacting because everything is so fast, that you don’t have time to think. There’s no way to dwell about things when you are on the ice.”

Over the years, he learned other coping skills as well.

“I had to learn – slowly but surely – to get outside of yourself; stop thinking about how you are coming across and start thinking about what it is you are trying to get across, and who you are doing it for. Once you get into that place, all that anxiety slides away.”

Catch Sportsnet hosts Ron MacLean and Tara Slone every Sunday as they travel across the country, stopping in different communities from coast to coast to celebrate local hockey stories, and the game’s biggest stars.

Each week’s event wraps up with a Sunday night NHL broadcast from the Sportsnet Mobile Studio.

ON HVAC

By Mark Rippon

Heat pumps and efficiencies Ductless air conditioners and heat pumps have been around for some time, but they are getting some real traction in the market lately, particularly with various incentive programs promoting them through rebates and financing.

With this in mind, a brief review of efficiency measurements may be helpful.

A common configuration for ductless heat pumps is the Air Source Heat Pump (ASHP). This can be used in a wide variety of applications, in most climate zones, and without ground or water loops.

This type of heat pump does not “produce” heat, rather, they extract heat from the air and then transfer those BTUs into or out of a building, depending on the season. In effect, the heat pump moves or “pumps” heat from one area to another, thereby heating the area it is pumping heat to, while cooling the area it is extracting heat from.

Air source heat pumps are available in a variety of configurations and capacities including: ductless, ducted, single head, multi-head and cold-climate versions.

To provide customers with a complete picture of costs, we need to look at the initial purchase cost as well as the cost to operate the equipment. This latter part of the picture is largely determined by energy efficiency.

Measuring efficiency There are four different measures used to describe the energy efficiency of heat pumps that we should be aware of: EER, SEER, HSPF and COP.

Energy Efficiency Ratio (EER) The ratio of the cooling capacity (BTUH) to the power input (watts) under steady state operation and specific conditions. A useful metric but since appliances will only operate under those conditions occasionally, it only tells part of the story.

Seasonal Energy Efficiency Ratio (SEER) A measure of the appliance’s cooling efficiency, defined as the total cooling energy output (BTUH) over the total electrical energy input of an entire cooling season (in watts).

Heating Seasonal Performance Factor (HSPF) In essence, the heating version of SEER rating. It is the total heating energy required for the season (BTUH) divided by the total electrical energy required for the season (W).

When looking at heat pumps, a lot of people will refer to the listed Seasonal Energy Efficiency Ratio (SEER) of the appliance, which is the most meaningful measure of efficiency in air conditioning. This would only be considering half the story and, the lesser half when it comes to Canada, given our climate.

Coefficient of Performance (COP) This is a ratio of the instantaneous useful heating or cooling provided, relative to the instantaneous energy input.

In most parts of Canada, the cooling season is much shorter than the heating season, so we should first consider how effectively and efficiently the equipment can heat our homes, since that will be its primary function in most cases.

Published HSPF ratings usually are for climate zone IV, however much of Canada is in climate zone V where the realized HSPF rating will generally be around 15 per cent lower.

But Coach…

I

had the pleasure of coaching Little League baseball for several years as my boys were growing up here in Alberta. Sports are filled with so many great metaphors and lessons about life. In fairness, I think it would be accurate to say ay that I learned more from those little men than they learned from me.

One such lesson was the persistence with which we hold on to beliefs and behaviours we’ve labelled as “true” or “right” in our own minds.

That is to say, when a boy believes he has the correct form and stance in the batter’s box, it can be difficult to offer constructive coaching.

He may hear you. He may even do what you’ve asked. Still, you’ll only truly know if he’s bought in when it’s game time.

So often, when the pressure is on, he goes right back to his old habits: “But coach, my way works just fine!”

And it is not just in baseball. The same behavioural pattern exists in business.

You have good people. You provide weekly training for them. You show them how to slightly modify their stance and form. They do it in the training environment. They understand it well enough to teach others. And still, they get out there with you customers, and they go back to the same old habits.

Sometimes your team needs to hear the same information you’ve been telling them come from someone else’s mouth. It’s a concept as old as humanity, so old even the Bible states, “A prophet is honoured everywhere except in his own town.”

I eventually learned my lesson and I brought in a batting coach. He told my team all the same things I did – in almost exactly the same way. And the kids ate it up like he was some kind of a baseball god. I chalk it up to the cool Toronto Blue Jays ball cap he wore. Gotta get me one of those hats…

Sometimes It Is the Messenger Even if you’re doing a really good job of training, you might be experiencing less than desirable results for one simple reason: familiarity.

Recognize that a failure in getting information through to your team is not necessarily a failure of your training skill. Sometimes, they just know you so well, they can predict what you’re going to say and how you’re going to say it.

There is something extremely powerful about third party validation; no matter how good you are, you’ll need outside help.

Thankfully, in today’s connected world, there are many simple ways to bring an outside voice into your weekly training meetings. Video curriculum is everywhere, as are facilitator and participant handouts. Tools like these make it easy to reinforce training concepts.

WINNING AT A NEUTRAL SITE If you want to fast-track your results, we’ve found that you need to go beyond video and send your team to offsite training. After an immersive training program with a professional facilitator, they will leave energized and enthusiastic—which translates into happy customers and solid revenue increases.
