< UPFRONT VARIETY IS THE SPICE YEARS AGO, IN THE MID-1980’S, I HAD MY FIRST BRUSH WITH CELEBRITY. I was on the same airplane, flying direct from Saskatoon to Toronto, with the young NHL scoring leader from that year, Wayne Gretzky.

My seat was closer to the back of the plane and Wayne was up front. We never met, but I’ve retold that story many times and it’s a memory that sticks.

That’s led me to wonder: “What makes something memorable?” I assume it’s when something happens to us that is out of the ordinary, and certainly an encounter with a celebrity, however fleeting, qualifies.

In this issue, Dave Demma remembers a refrigeration service call he made in the mid-1970s to a storied music venue in San Francisco. The Winterland Arena echoes with memories of music legends from the late 1960s, and for Dave that fact along with the facility’s vintage refrigeration system keep that experience alive for him.

I believe that with the wide variety of work HVAC/R workers and plumbers get up to on a regular basis there must be plenty of memories made. While most mechanical projects and service calls may be somewhat routine, I’m sure most every person involved in this industry has some ‘out of the ordinary’ stories to tell.

I picture installing bathroom fixtures in a celebrity’s house, laying a snow melt system in a famous person’s driveway, designing the heating system in a landmark building or air conditioning in an exotic location as being the type of work that leads to colourful stories among friends and indelible memories.

The truth is, we all face ‘out of the ordinary’ experiences every day to some degree, but the more we put ourselves out there and embrace new adventures, that’s when the real memorable events happen.

Taking on new challenges in our worklife, like exploring different technologies or learning another skill is one small way to create new ‘out of the ordinary’ experiences. It’s hard to manufacture memorable moments, but keeping variety in your life is one way to encourage more.

And sometimes it’s just luck. Me and Number 99 on the same plane—it’s never happened again. <> – Doug Picklyk, Editor

COMMERCIAL FIRE TUBE BOILERS

Navienâ&#x20AC;&#x2122;s new NFB-C Commercial Condensing Fire Tube Boilers are available in two sizes: NFB-301C (301 MBH) and NFB-399C (399 MBH).

Each NFB-C boiler uses the same in-house designed and manufactured patented heat exchanger technology that was introduced with the NFB series in 2018. The heat exchanger is robotic laser welded and the combustion chamber is form-pressed to minimize the number of weak points that could be prone to thermal stress and corrosion. Oval shaped tubes within the heat exchanger contain internal turbulators designed to improve both the heat transfer rate and the structural integrity of the assembly. A specific water flow is generated by baffles inside the heat exchanger to extract the maximum amount of heat from flue gasses while the non-metallic base provides additional protection against corrosion caused by acidic condensate.

The industry leading 97.5% thermal efficiency NFB-C series includes top and bottom piping connections for installation flexibility and an advanced 7-inch colour touch screen display with easy intuitive navigation for setup, troubleshooting and operation. The built-in circuit board allows connections for a boiler pump and 3 zones pumps using dry contact relays, and also includes a DHW priority zone. The NFB-C series commercial fire tube boilers offer up to a 15:1 turndown ratio and extremely low NOx levels, certified by SCAQMD to meet the most stringent code requirements.

Low exhaust gas temperatures allow the NFB-C to be installed using multiple venting options including PVC, CPVC, polypropylene and stainless steel. NFB-C can be installed with 3" venting up to 60 feet or 4" venting up to 150 feet.

Many accessories are included as standard while optional accessories allow each NFB-C boiler to connect to building management systems through Modbus, BACnet or LonWorks protocols. NFB-C boilers are NaviLink WI-FI remote control compatible, cascade capable up to 16 units, common venting capable up to 4 units and are certified for high-altitude installations up to 10,100 ft. with NG and LP gases.

MIND THE LABOUR GAP

Canadian construction industry needs over 300,000 worker recruits over the next decade.

BY DAVID KENNEDY

KEEPING UP WITH DEMAND Contrary to its 2019 analysis, which projected that industry growth would plateau in 2020, BuildForce now sees construction continuing to expand through the mid-2020s. It pointed to the country’s improved economy and immigration-driven population growth as two 16

key factors for the shift.

On the residential side, the research organization forecasts greater activity in provinces with younger populations, such as Alberta and Saskatchewan, from now until 2029. Quebec and Atlantic Canada, conversely, are likely to see housing starts slip. The increasing popularity of less labour intensive multi-unit residential projects will also cannibalize some of the residential business traditionally dominated by single family homes. It is estimated that 22,700 fewer workers will be building new homes by the end of the decade.

To pick up any slack, BuildForce projects housing renovation and maintenance requirements to rise “steadily” through 2029. Overall by that time, 17,100 more workers are expected to be engaged in the residential sector compared to 2019.

Employment in the non-residential construction sector will also be up considerably a decade from now. BuildForce anticipates the sector will add 33,100

positions by 2029, with an “explosion” of major new public transportation, infrastructure, health care and energy projects as the primary factors.

PROVINCIAL HIGHLIGHTS On the West Coast, B.C. 's construction industry will benefit from the new LNG Canada export terminal in Kitimat, renewed work on the Trans Mountain pipeline and several new infrastructure projects, such as the Pattullo Bridge replacement and transit work in Vancouver.

Ongoing construction on the Site C dam and the Vancouver International Airport expansion are also major contributors to forecast growth in the province.

In neighbouring Alberta, the Trans Mountain pipeline as well as major petrochemical facilities near Edmonton, will help drive growth, BuildForce says.

The outlook in the other Prairie provinces is more muted with growth accelerating in Saskatchewan starting in 2021 as a result of mining and utility

The construction labour gap isn’t getting much narrower. The impending retirement of a generation of workers and continued growth in the industry means employers will need to coax more than 300,000 Canadians into lacing up steel toed boots over next decade to keep pace with demand.

Between 2020 and 2029, research organization BuildForce Canada projects 257,100 retirements and the creation of 50,200 new construction jobs across the country—enough to fill 307,300 vacant positions.

Of course, new recruits will also be stepping onto job sites during that time period. Even accounting for the expected entrants, however, the industry will likely come up well short of its labour requirements by 2029. Based on historical trends, BuildForce, which released its latest national labour forecast Feb. 10, expects the industry to see an influx of 227,600 new workers 30 or younger over the next decade. The recruits will fill about three quarters of available positions, leaving an approximately 80,000-job gap.

Though forecast recruitment comes close to keeping up with retirements, continued growth in the Canadian construction industry will add fuel to the looming worker shortage.

TACKLING THE UNDERLYING PROBLEM There are few easy solutions to the labour crunch as the tail end of the Baby Boomer generation ages out of the workforce. Still, BuildForce anticipates the industry will employ some stopgaps to get projects built in 2020 and 2021 with labour markets at their tightest. Relocating workers is one prominent example.

“Meeting anticipated peak employment demands in British Columbia and Ontario will likely require significant levels of interprovincial mobility,” Ferreira said. “Accessing workers from provinces where market conditions have softened will be critical.”

This strategy has its limits. “As demographic conditions unfold, there is an expected downward trend in provincial levels of unemployment that may lead to less workers being available for mobility to meet changing requirements across provinces,” the report notes. “This trend suggests that—even if the full potential of interprovincial mobility is realized—industry will likely still need to expand recruiting efforts for new workers from local sources of labour, from other industries, and from new immigrants to meet the industry’s long-term needs.”

Builders, industry associations, governments and educators all have a role to play in bolstering recruitment. In recent years, numerous collaborative efforts aimed at funnelling more students toward skilled trades and other construction careers 18

sector projects, but declining again beyond 2025. In Manitoba, with work peaking on the Keeyask dam and the Enbridge Line 3 pipeline expansion employment requirements in the province will likely decline through 2023.

Ontario’s labour market is expected to remain very tight, though BuildForce expects it to peak in 2020, largely as a result of work on multiple light rail transit projects and “overlapping demands” from a pair of nuclear refurbishments. The organization forecasts a second peak in 2026 with Toronto transit expansions and numerous large hospital projects..

It’s a similar story in Quebec, where projects such as Montreal’s Réseau express métropolitain, the Blue Line subway extension and Quebec City’s LRT will drive growth.

Looking east, New Brunswick construction activity is expected to remain stable over the next decade, backed by residential renovation work. Likewise in Nova Scotia, BuildForce forecasts a relatively stable market after a “surge” in activity over the next two years due to new hospital projects. PEI, which experienced a building boom over the past several years driven by population growth, will see that continue this year, though it's expected to moderate as the 2020s draw on.

Finally, a declining population in Newfoundland and Labrador and the completion of major projects in the next two years will see the province’s construction force slip back to lower levels.

Distribution of Canadian construction employment in 2020.

have gotten off the ground. A video series called Job Talks Construction is one of many examples. The initiative, spearheaded by the Residential Construction Council of Ontario (RESCON) and other provincial and regional construction groups, looks to tune both students and educators into the opportunities in construction.

With 22% of the current construction labour force expected to retire by 2029, recruitment pushes across the country are designed to buck the historical trends that forecast 227,600 new workers will enter the industry over the next 10 years.

Wider demographic trends won’t make it easy.

Canada’s population is expected to continue growing in the coming decade, but not as quickly as in recent years. Meanwhile, the country’s increasing number of retirees will lead to a fiercer competition for talent, tightening the labour pool. The construction industry will need to turn to traditionally underrepresented segments of the population to land more recruits.

BuildForce points to women, Indigenous people and new Canadians as three key groups.

In 2019, for instance, the report notes just 191,700 women worked in construction — compared to about 1.25 million men. While women accounted for 41.2% of off-site roles, only 4.7% of on-site staff were women.

Likewise, Indigenous people made up 4.9% of the total construction population in 2019. With Indigenous populations being the fastest growing in Canada, it’s an important focus area for the industry.

Finally, the building industry needs to make strides to attract more new immigrants—traditionally a substantial part of the construction workforce—BuildForce says. Unlike past immigrant populations from Europe and the Americas, today’s immigrants, most of whom come from a range of countries in Asia, are less likely to take up construction. <> www.buildforce.ca HPACMAG.COM

EZ GEAR SENSOR FAUCETS

COUNT ON IT LASTING EZ Gear Sensor Faucets deliver reliability, precision, and efficiency to your commercial restroom.

Inside each faucet, the ceramic disc cartridge eliminates old compression sealing technology.

Fewer moving parts disrupt the water pathway to diminish wear over time and reduces the water hammer effect causing for less wear on the faucet and the entire water line system. The EZ Gear Technology lasts up to 1,000,000 cycles…and counting.

The thoughtfully designed and positioned sensor intuitively detects the user without delay, too much force, or wasting water. The low-flow rate also helps reduce water use and costs.

Gear up for the next generation of sensor faucets.

ZW5000/5004 SERIES

LESS FORCE, MORE FLOW With the lowest torque—only 9 ft lb—the PressureTru ZW5000/5004 Series Pressure Reducing Valve adjusts easily during installs and fire emergencies.

For contractors, its compact size fits in any application, new or retrofit. For fire personnel, the design regulates pressure under both flow and no-flow conditions. For the design engineer, the ZW5000 provides up to 30 psi in higher residual outlet pressure than competitor models. The tamper-proof shield drops out for adjustments in the field and breaks away in the case of emergency.

When it comes to control, the ZW5000/5004 Series keeps it with the pros. Coming soon to Canada.

BUILDING PERMIT VALUES RISE TO $8.7B IN DECEMBER The total value of building permits in Canada has climbed 7.4%, up to $8.7 billion in December 2019.

According to a report published by Statistics Canada, increases were reported in five provinces with Ontario and Quebec leading the way with 10.5% and 15.8% increases respectively.

The total value of permits for multi-family dwellings was up 15.9% to $2.9 billion in December, mostly due to large projects in the census metropolitan areas (CMAs) of Montreal and Vancouver.

In Montreal, the value of commercial permits rose 19.7% to $2 billion in December. This is largely due to plans for the carbon-neutral “Royalmount” multi-use commercial development.

Meanwhile, the value of institutional permits rose to its highest level since September 2017 (+10.8% to $1 billion). This is largely due to permits for the redevelopment of the Centre for Addiction and Mental Health (CAMH) in Toronto.

Conversely, the total value of permits for single-family dwellings has decreased by 3.2%, down to $2.2 billion, with the largest decline being in Ontario (-$76 million).

The total value of industrial permits has also declined by 21% to $583 million, following strong gains in November.

Overall, municipalities across Canada issued $102.4 billion worth of permits in 2019, up 2.6% compared with 2018. www.stancan.gc.ca

U OF WATERLOO DEVELOPS NEW SENSOR Researchers at the University of Waterloo have developed a battery-free sensor to detect water leaks in buildings at a fraction of the cost.

The tiny sensor uses nanotechnology rather than clunky batteries to power itself and send alerts to smartphones when exposed to moisture. By eliminating a battery and related circuitry, researchers estimate their sensor could be commercially produced for less than $5.00 each, approximately one tenth of the cost of current leak detection devices on the market.

“One of the big issues related to water damage in buildings is that owners don’t install enough sensors because they are too expensive,” said George Shaker an engineering professor at Waterloo, in a release. “The much lower cost of our sensor enables the deployment of many, many more to greatly improve protection.”

The new sensor is smaller than a nickel and measures five millimetres in diameter. It is comprised of stacked nanoparticles which, when exposed to water, trigger a chemical reaction that produces enough electricity to power a wireless radio and additional sensors to record environmental conditions such as temperature. The wireless radio and other sensors are on a circuit board packaged with the leak sensor in a box just three centimetres square.

“We harvest the energy that is created when the sensor is exposed to water and that energy then powers the electronics to send an alert to the user’s cellphone via the internet,” said Norman Zhou, a mechanical and mechatronics engineering professor at the university, in a release.

In addition to being cheaper, the new sensors are environmentally friendly, reset after use, can be installed in hard-toreach places—including otherwise inaccessible areas during building construction—and require much less maintenance.

While they are exploring commercialization, researchers are also pursuing additional applications for the underlying technology, including in diapers for the elderly and in bandages to detect wound leakage after surgery.

“We believe this has the potential to solve several important problems,” Shaker said.

STUDY: CLEANER RESTROOMS CAN INCREASE CUSTOMER SPENDING The old saying might be ‘don’t judge a book by its cover’, but customers are certainly judging businesses by the state of their washrooms.

Bradley Corporation’s 11th Annual Healthy Handwashing Survey asked 1,006 adults and youth throughout the U.S. questions about public restrooms. Of those surveyed, 60% said they are likely to either leave a business immediately or never return if they encounter an unpleasant restroom.

Conversely, 62% of the customers surveyed said that they were more likely to spend more money at an establishment if it restrooms were clean and well-maintained.

The survey also revealed a number of common grievances in public restrooms. Among the most aggravating are clogged/ unflushed toilets (85%), empty/jammed toilet paper dispensers (83%) and partition doors that don’t latch shut (78%).

The study also found that almost three out of every four Americans make it a point to visit a business because they know it has nice restrooms. Women are especially likely to

HIGH BIM USAGE REAPS MULTIPLE REWARDS A new study of mechanical and HVAC contractors in the U.S. who use building information modelling (BIM) has revealed multiple benefits relating to cost, scheduling, productivity and lower labour costs.

The study, which was conducted by Dodge Data & Analytics, was carried out in partnership with the Mechanical Contractors Association of America (MCAA), Pinnacle Infotech and the Air Conditioning and Mechanical Contractors’ Association (AMCA).

According report, contractors who are sophisticated users of BIM software have seen the benefits. However, the study also demonstrates that the ability of these contractors to fully leverage the value of modelling technologies is hampered by training and manpower issues.

“Virtual construction has come a long way in a very short time,” Scott Pittman, vice president of Pinnacle Infotech, said in a release. “The days of the chalk line and paper documents are decreasing, and we are seeing more laser scanners and layout tools to help with modular construction and pre-manufactured assemblies.”

A significant benefit is the ability of BIM to improve the fabrication process. Many mechanical contractors are users of offsite fabrication, and the study shows that nearly half use BIM on 50% or more of the assemblies they prefabricate. Over 80% of those who use it to prefabricate report improvements in material waste, labour costs, quality of installed work, avoiding the purchase of extra pipes and fittings and schedule performance.

By using BIM, mechanical contractors have also been able to leverage the technology to conduct more analysis on their projects. Over 70% reported using BIM for shop drawings and spatial coordination on half or more of their projects. Nearly two thirds (61%) reported using BIM for constructibility evaluation on over half of their projects.

“BIM is an increasingly important and incredibly complex part of the building process,” said Sean McGuire, director at MCAA. “It requires additional coordination, planning and design expertise. This new process is still in its infancy, and mechanical contractors—especially those that are already using BIM—have a lot to learn from this report.”

INTERNATIONAL CODE COUNCIL UPDATES PLUMBING AND MECHANICAL CODES The U.S.-based International Code Council has announced the release of its 2021 International Plumbing Code (IPC) and International Mechanical Code (IMC).updates.

The updates, which were announced on Feb. 11, apply to the U.S. jurisdiction, however the code development process draws upon the expertise of plumbing, mechanical, building and safety experts from across North America.

The IPC and IMC are revised and updated every three years for the purposes of integrating new technologies and scientific understandings.

“It’s critical for our codes to adapt to new building practices, technologies and societal needs. Our 2021 IPC and IMC take these needs into consideration and aim to promote safety above all else,” Dominic Sims, Code Council CEO, said in a release. “Construction is ever-evolving, and how we prepare trades professionals matters more now than ever.”

Some additions/updates to the new Plumbing Code include: • multiple-user toilet facilities to serve all genders now permitted • two new methods for relining/rehabilitating existing sewers added • accommodations for mounted rooftop solar panels over vent terminals added • CSA B805/ICC 805 Rainwater Harvesting Systems is now allowed as an alternative design method.

In 2019, the Code Council commissioned an independent analysis of the HPACMAG.COM

costs and savings associated with building under the IPC. The study found that over a 12-year period, counties in the U.S. that used the IPC saved $38 billion in construction costs and emitted one million fewer tons of carbon dioxide.

The updated Mechanical Code establishes minimum requirements for mechanical systems using prescriptive and performance-related provisions. The 2021 additions/updates include: • Clothes dryer exhaust terminals are now required to be at least three feet from any opening into a building.

• Polyurethane spray-applied foam on the exterior of ducts in attics and crawl spaces is now required to meet specific smoke and flame index limits.

• Fire and smoke dampers must now be provided with approved access for inspection and maintenance.

TOUCHY FEELY Give your temperature controllers 20/20 vision. BY JOHN SIEGENTHALER

E

very hydronic system has one or more controllers that measure and respond to temperature. Common examples are temperature setpoint controllers, outdoor reset controllers, mixing controllers and differential temperature controllers.

Most of these devices use thermistor sensors, or more specifically NTC (negative temperature coefficient) thermistor sensors. These solid state devices decrease their electrical resistance as their temperature increases and vice versa.

Figure 1 shows a temperature versus resistance chart for a “10K” NTC thermistor sensor that’s commonly used in the hydronics industry. The 10K designation indicates the sensor’s resistance of 10,000 ohms at 25C (77F).

The relationship between the sensor’s temperature and its electrical resistance is not linear. Changes in resistance are much more pronounced at low temperatures. Even so, this relationship between temperature and resistance is very repeatable. Modern digital HVAC controllers can easily translate the electrical resistance of the sensor circuit into an inferred temperature value based on a known and repeatable curve such as shown in figure 1.

The type of thermistor sensor used in most HVAC applications consists of a small sold state thermistor bead, an enclosure and lead wires. Thermistor beads can be very small and

have very fine attached wires. Figure 2 shows just how small some thermistor beads are.

Tiny thermistor beads with fine wires don’t lend themselves to the handling and placements required in HVAC applications. The solution is to encapsulate the bead in an enclosure that can withstand more physical force and connect it to lead wires rugged enough for installers.

During manufacturing the lead wires are soldered to the thermistor bead (or a tiny circuit board holding the bead). This assembly is then inserted into the enclosure, and a potting material is poured in to permanently seal it in place and protect it against moisture.

Sensor enclosures are made of a highly conductive metal such as copper, brass or stainless steel. The high conductivity minimizes the difference between the temperature of the surface the sensor is mounted to, and the temperature at the thermistor bead. For most heating or cooling system control applications this temperature difference is tiny and of no concern.

Most thermistor sensors used in hydronic systems have HPACMAG.COM

lead wires that aren’t long enough to reach from the installed location of the sensor to the controller. A cable must be use to complete the circuit between the sensor and controller. The sensor and cable combined forms the sensor circuit, and the resistance of the sensor circuit is what the controller “feels.”

Anything that adds significant resistance to this circuit makes the controller think the temperature at the controller is lower than it actually is.

Designers should verify the minimum wire size (e.g., the highest AWG #) that the controller manufacturer allows for connecting the sensor to the controller. Also verify the maximum allowed sensor cable length.

I prefer nothing smaller than 18 AWG copper wire for 10K thermistor sensors. That wiring has a resistance of 0.0064 ohms per foot. If a thermistor sensor was located 250 feet from the controller it would require about 500 feet of sensor wire. The total resistance of that wire would be about 3.2 ohms. This would add to the resistance of the sensor itself.

For a 10K thermistor at 77F, the cable would only represent 0.03% of the circuit resistance. It would have no significant effect on the operation of a hydronic system.

Smaller diameter wires (with higher AWG #s) have higher resistances. For example, the resistance of 24 AWG copper wire is about four times more than 18 AWG copper. It’s also more fragile.

The bond between the sensor lead wires and the sensor cable can add significant resistance to the circuit. One situation where this becomes an issue is where sensor lead wires are connected to cables using standard wire nuts and then exposed to moisture. The moisture can collect within the wire nut and cause corrosion at the junction. Over time this increases the resistance of the sensor circuit, and it “fools” the controller into thinking the sensor temperature is lower than it actually is.

This was a common problem with early generation solar thermal systems where the wire nuts connecting the sensor lead to the cable were exposed to weather. If you need to join the leads from exterior located thermistor sensors to a cable make every effort to locate the joint inside and where it’s accessible.

If the joint has to be outside, make it with the gel-fired compression connectors used for exterior telephone wiring connections. An example of such a connector is shown in figure 3. The gel inside these connectors provides a waterproof seal of the electrical bond.

Sensor circuits can also be affected by strong electromagnetic fields. Such fields can induce currents in sensor cables that inevitably will throw off the controller. To reduce the chances of such interference, never run sensor cable next to or in the same conduit as AC wiring.

If the sensors must be installed near devices such as large motors, light ballasts or large transformers, use cabling with twisted pair wires, or even better,

shielded cable. The latter has a metal foil layer between the exterior insulation and internal conductors. Only one end of this metal foil should be fastened to an electrical ground. The other end of the foil should be electrically isolated and not be fastened to anything.

MOUNT UP Most current generation digital temperature controllers offer excellent accuracy and reliability. However, these controllers can only respond to the information they receive from their sensor(s). If the sensors are improperly mounted the temperature the controller detects can be very different from the temperature the sensor was intended to detect.

Figure 4 shows an example. The temperature sensor seen in the yellow cloud is taped to the copper tubing. It’s intended purpose was to detect the water temperature in the upper portion of a thermal storage tank seen in the lower portion of the photo. Instead it’s detecting a temperature somewhere between that of the tube surface and the surrounding air temperature.

This sensor is connected to a controller that turns a pellet-fired boiler on and off—supposedly based on the temperature in the upper portion of the thermal storage tank. Needless to say, that boiler was not operating as expected.

When the temperature of fluids contained in tanks is to be measured, the sensor should be mounted in a well that’s threaded into an appropriate Continued on p34 MARCH 2020 | HPAC

tank tapping. Prior to inserting the sensor, a small amount of thermal paste should be injected into the end of the well using a plastic syringe. The sensor body should also get coated with thermal paste (see figure 5, previous page).

The objective is to completely fill the gap between the sensor body and inside surface of the well with thermal paste.

Doing so improves conductivity, and reduces the time lag between changes in water temperature and when that change is detected by the sensor.

Figure 6 shows a Honeywell 121371B copper sensor well, and a ⅜-in. diameter thermistor sensor that fits properly inside this well, leaving just enough space for thermal paste.

These wells are available in either ½-in. or ¾-in. MPT threads. Many thermal storage tanks have ½-in. or ¾-in.

FPT threaded tappings to receive these wells. When this type of well needs to go into tanks with 1.5-in. or 2-in. FPT tappings, use a brass bushing for the size transition.

It’s also possible to mount sensors to the surface of copper tubing. Some sensors have a small concave channel on their housing that allows that housing to “saddle” the pipe, and thus have more contact surface area.

Sensors mounted to copper tubing should be secured with a two nylon pull ties that are rated to handle the temperature the pipe may experience. Inferior pull ties will harden over time and break.

A small dab of thermal paste should be placed between the sensor and pipe surface. After the sensor is secured with the pull ties, a nominal 6-in. length of insulation should be placed and centered over the sensor. The insulation sleeve should be sealed from air penetration at both ends. I like to use a high-grade electrical tape for this sealing.

It’s also possible to make a sensor well using copper tubing closed at the end with a soldered cap. The length of the well is whatever you need. This is 34

especially helpful when you need to place a sensor at a specific height within a tank, as shown in figure 7.

For example, a ⅜-in. type M copper tube has an inside diameter of 0.450 in.

A ⅜-in. diameter sensor housing fits into this tubing, leaving about 1⁄32 -in. gap between the sensor house an inside of the tube. This gap should be filled with thermal paste. The ⅜-in. copper tube can be sealed to a brass socket of the ¾-in. dielectric union using a ¾-in. ftg x ⅜-in. C reducer coupling.

If you’re planning a long sensor well inserted through a connection at the top of the tank, be sure there’s adequate head room to insert it after the tank is in place. If there isn’t you’ll need to insert the well before the tank is rotated into its vertical position.

It’s also important to provide strain relief for the wires connecting the sensor leads to the cable. A temperaturerated zip tie holding the sensor cable to the exterior portion of the well, or other nearby solid surface, is generally acceptable.

Finally, be sure you label and tag every sensor in the system. Label the sensors on the piping and electrical schematics as you design the system, and attach tags to the sensors as they are installed.

Sensors are the “eyes” of temperature controllers. Those controllers can only react to what they “see.” Careful sensor placement and mounting is critical to giving those controllers 20/20 vision. <> John Siegenthaler, P.E., is a mechanical engineering graduate of Rensselaer Polytechnic Institute and a licensed professional engineer.

heat loss calculation for a project like this, so do not skip this step. The following is just an example with fictitious numbers for the purpose of this article.

To begin, we will be considering a home of about 2,000 sq. ft , at letâ&#x20AC;&#x2122;s make it 20 BTUh/sq.ft. to keep the math easy, which would yield about a 40,000 BTUh heat loss.

If the outdoor design temperature is -20C, then we know (based on heating capacities discussed in the previous article) that the particular ATWHP in this example could only produce about 6 KW or 20,000 BTUh on this outdoor design day, and we would require supplemental heat of an additional 6kw or 20,000 BTUh to heat the home. Keep that in mind when we

look at the mechanical for this example.

Supplementary heat could come from anything, but since we are fossil fuel free, letâ&#x20AC;&#x2122;s go with electric backup here.

HEAT EMITTERS Before we proceed to the mechanical and the control logic behind this system, I want to draw attention to the heat emitters we would choose for this home given the limited fluid temperatures we have available for heating and cooling.

High mass radiant floor heating would be an obvious choice for heating, but radiators and fan coils are not to be forgotten. Heat emitters can be upsized in surface area to work with lower fluid temperature for heating. Looking at a HPACMAG.COM

n the last issue of HPAC Magazine I introduced part one of this article, which included a brief explanation on the growing adoption of air-to-water heat pump (ATWHP) systems in Europe and why that trend, supported by the move to decarbonization and electrification in North America, will lead to growth of these systems closer to home. I also provided a basic explanation of the technology, its strengths and limitations, and how more recent developments are expanding their capabilities in colder weather climates.

In this article I will go through a very high-level system design example including control logic. Nothing will, or should ever, take the place of a proper

Figure 1 – Fan coil output example for available fluid temperatures. For heating and cooling in our home example, the unit shown in the middle (CW036…) would satisfy the requirements.

fan coil, as an example, as it would be usable for both heating and cooling season, one would need to ensure its output requirement can be achieved with the fluid temperatures available. See the example in figure 1 for a suitable fan coil example.

DHW A similar consideration must be kept in mind when picking an indirect domestic hot water (DHW) tank for potable requirements. Given the lower fluid temperature available from a heat pump, the surface area of the coil inside of the tank must be much larger than that of a tank that would be fed by a high temperature boiler.

Depending on the manufacturer, some have specific models available for this kind of application and often feature surface areas between 29- to 35-sq.ft. (2.7- to 3.3-sq.m.) of heat exchanger, allowing for DHW production of 50C (122F) potable water with 60C (140F) fluid delivered from the ATWHP.

PIPING There are several ways to pipe an ATWHP into a system. One of such, but surely different approach than most would be familiar with, is shown in Figure 2 (page 40). Please pay careful attention to flow direction and the strategically placed flow check valves in the piping.

Let’s review this piping diagram in a little more detail. Follow the red supply pipe leaving the ATWHP and follow it going into the return of a backup electric boiler. From that electric boiler, the piping leaves out of the supply and moves HPACMAG.COM

to a branch. From this branch, either P1 will create the flow in a heating or cooling requirement, or, P2 will create the flow through the indirect DHW tank.

It would be an either/or scenario, where the DHW tank would typically be the priority. In a heating or cooling requirement, P1 would create the flow through the buffer tank only and return the fluid back to the ATWHP. The two parallel horizontal check valves above P1 ensures flow can only go into its appropriate direction.

Up higher, P3 is what would be creating the flow for any heating and/or cooling system. Remember, those could be any types of heat emitters or a mixture thereof, as long as they are sized appropriately for the fluid temperatures available for the system.

Take a minute to review this in your mind by imagining only one of the two pumps would be running at any time.

You will see how the check valves will fix the direction of flow as would be desired. Those check valves, as well as the bridge that you can see the S3 sensor on, create a means of hydraulic separation between the two. In practice, P1 and P3 would be able to run together if there is a call for heat or cool in the building (P3) and heated or cooled fluid needs to be added to it (P1).

CONTROL LOGIC Now let’s examine the high-level control logic that could be employed. The inverter driven ATWHP will always automatically regulate its output to maintain desirable delta-T across supply and return in any call. Delta-T and flow

rate through the heat pump can vary to best match the current need.

The DHW tank is typically set to be the priority. The ATWHP control system would have the option to provide priority only during certain hours of the day if so desired. The setpoint for the DHW Tank (50C or 122F) is set in the controller and a desired ON differential is set (5C or 9F).

When the tank temperature drops below setpoint by the ON differential, a call for DHW is generated and the heat pump is modulated to achieve 60C or 140F leaving fluid temperature until the tank is satisfied and back at setpoint.

If required, and only when it is colder than -5C or 22F outside (remember the temperature output limitations?), the electric boiler is enabled to supplement the DHW production requirement. The electric boiler, in this example, has its own onboard two stage controller to operate and stage its internal two 3KW elements. Its setpoint should be set at least 5C or 9F higher than the highest ever required fluid temperature for any call.

The system controller also allows for scheduled DHW Tank temperature boosts to accommodate for legionella prevention. The electric boiler is utilized to elevate the fluid temperature from the ATWHP sufficiently to achieve this safe temperature boost.

This system’s heating or cooling mode is adjusted using an outdoor temperature disable setpoint (IE: <18C or 64F) for heating and outdoor temperature enable for cooling (IE: >21C or 70F).

These setpoints, along with adjustable Continued on p40 MARCH 2020 | HPAC

time delays, must be met in order for one mode to switch to the other. A stand-alone thermostat, set-up for the same heating and cooling disable or enable setpoints and time delays as the system control, will then operate the fan coil and enable the P3 pump as necessary to maintain the desired comfort.

With P3 enabled, flow past the S3 sensor will trigger a demand with the system controller and it will then modulate the ATWHP to maintain a water temperature that is either reset based on outdoor temperature or to a fixed setpoint temperature. This system controller would have the ability to setup a reset or setpoint water temperature control for heating and/or for cooling.

So to summarize, S3 is used to gauge the level of demand from the system (larger delta-T = higher demand) and the heat pump is modulated using its supply S1 and return S2 sensors. As always, an operating differential will vary based on load/demand in the system.

â&#x20AC;&#x153;A general rule of thumb is that a heat pump should not run more than three times an hour to ensure its life cycle is not compromised.â&#x20AC;?

BUFFER TANK

SET UP OPTIONS

A 30-gallon buffer tank is used to add mass to the system to ensure proper and lengthy run-times for the heat pump light loads throughout shoulder seasons. A general rule of thumb is that a heat pump should not run more than three times an hour to ensure its life cycle is not compromised. The fluid volume will help ensure those run times.

In the winter months, a heating cycle of the heat pump can and typically will ice up the refrigerant coil in the heat pump. The 30-gallon from the buffer tank is also used during the defrost cycle, where the volume of fluid is now taken advantage of to provide quick defrost and to minimize down time during peak demand.

Some ATWHPs are available for purchase with just the outdoor heat pump by itself and a contractor/installer can build his own mechanical and control system to satisfy his application needs.

Others offer complete systems that go together in plug-and-play fashion to provide an efficient installation time-wise.

This option provides a complete system solution that has been tested with a control logic and hydraulic piping arrangement to make it duplicable on the next job, while keeping the installation costs as close to being fixed as possible.

The example I provided in this article was geared towards smaller residential applications, and I am sure it was noted that this is just one of several examples for making a system work.

More advanced and larger residential applications may need multiple ATWHPs staged together for heating and cooling needs. In some of these systems certain parts of a building may need heating while others are looking for cooling. A much more advanced control strategy would be required for those applications. As they typically increase in costs very quickly, some systems need the flexibility that those can provide. Perhaps there will be more on that topic in future articles. <> Mike Miller is director of sales, commercial building services, Canada with Taco Inc. and a past chair of the Canadian Hydronics Council (CHC).

HELP!

BY IAN McTEER

Help, I need somebody Help, not just anybody Help, you know I need someone. Help!

T

he Beatles’ famous lyric might apply to just about everyone at some time in their lives, but tradespeople, especially HVAC mechanics, often require specialized help and usually at the most inopportune time.

I’ll never forget my being dispatched to a no heat call on a boiler with a rosette burner, soapstone pilot and bizarre mechanical gas valve; Help!

With precious little written material left behind and still many years before the smart phone, my only alternative was to telephone, from the customer’s phone, to my dispatcher and admit I could not repair the unit.

At one time in the trades, asking for help might have reflected badly on one’s competence, hence an isolated technician might have otherwise struggled mightily in ignorance and frustration literally bull-moosing a way out, whatever that might have entailed.

Fortunately for me, a tech with rosette burner experience was nearby and met me on the job. I learned all about soapstone pilot burners in 10 minutes; maybe there’s one left in an HVAC museum somewhere!

Today’s HVAC equipment is sophisticated requiring technicians to have a vastly greater built-in library of knowledge.

Not only that, how one procures necessary information has become a fundamental skill. Installers and service technicians should be familiar with these aspects of HVAC philosophy, namely: • Specification: why is this machine doing this job?

• Installation: is this unit installed properly? Maybe that explains all these service calls.

• Commissioning: has this unit been set-up to do this job?

• Maintenance: how long since the coils were cleaned, blower wheel inspected?

GETTING HELP Who hasn’t heard the telephone announcement, “All of our agents are busy serving other customers” while making a phone call for assistance? An HVAC technician working on a downed rooftop unit during a polar vortex cannot tolerate be44

HPAC | MARCH 2020

“For any technician whose entire bag of tricks has been exhausted on a unit, calling a manufacturer’s technical rep is likely a last resort.” ing told, “Your estimated wait time is 58 minutes.”

I don’t want to sound patronizing having been in the position of needing help “right now” more than once over the years, but technicians must build up their skills and have confidence in themselves. Even with experience gained over time, the dynamic nature of our industry means Benjamin Franklin’s pithy saying from the 1750’s, “there are no gains, without pains” is ever truer today.

The pains, for HVAC technicians, are constantly running into unfamiliar products, whether new or old, combined with incomplete documentation, bizarre fault codes (Err 179.04, INV T EX DER…what?) and the secretive nature of some manufacturers trying to exclude smaller contractors or otherwise non-approved servicers from profiting ahead of their dealer families. The gains, of course, are properly serviced units doing precisely what their owners expect of them. Such gains are the key to future business.

ISTOCK/GETTY IMAGES PLUS

TELEPHONE HELP An HVAC manufacturer’s practice of establishing dealer networks and favouring everyone involved is a business philosophy that has stood the test of time. However, regardless of one’s allegiance, improperly functioning equipment creates no end of trouble for the end user. For any technician whose entire bag of tricks has been exhausted on a unit, calling a manufacturer’s technical representative is likely a last resort. Knowing who to call is just one part of the battle, more on that later.

Having fielded many calls from techs, here’s some advice on etiquette gleaned from my experiences: • You may be frustrated, such a feeling is perfectly understandable, but please, do not start the conversation with, “that piece of junk your company makes is garbage.”

Instead, say something like, “I’m not used to working on this product, and there’s no information left behind to help me get it going.”

• Always have the unit model and serial number available.

Include the date of installation (if known) or other descriptors like the unit appears to be installed improperly; provide details.

• Ask if a Technical Service Bulletin has been issued for this problem.

• Mention everything you have done so far, include all relevant data like “the suction pressure is 125 psig,” or “I cleaned the coils and blower wheel,” or “the input voltage HPACMAG.COM

Figure 1. Photo sent with detailed markings

is 232 VAC.” Don’t say, “everything is fine.” Be able to provide, for example, working gas pressure even though it may not seem relevant to a control board lockout problem.

Saying the gas pressure “is fine” is not helpful.

• When working on rooftop or other outdoor equipment, in summer or winter, be sure to find a place out of the wind before placing a call. The phone’s microphone is easily overwhelmed by the wind, and your voice will be completely drowned out. This is especially difficult when the rep asks you to perform various tests and component checks. I empathized with technicians, especially during the polar vortex, doing their best to not only get the customer heat, but to stay warm as well. It’s more than a little difficult to probe a well-hidden circuit board for a 10 volt turn on command signal with bare fingers and a fierce wind blowing up one’s backside.

• If you have a smart phone, it may be possible to send a picture or video but be aware that for security reasons, such helpful tools may not be allowed into the company’s network.

A technician inquiring about a venting situation once sent me a photo (see Figure 1) to my personal phone with relevant detail marked on the image. My answer was, “No, that’s not the correct set-up, details following.” In my experience, such phone calls resolved many problem scenarios, however, there were several situations that involved a site visit.

HELP IS NEARBY

SITE VISITS When documentation is lost or unavailable, be sure to examine the unit’s door panels for valuable information such as this list of control board flash codes.

Assuming the door sticker is still there or even readable, be sure to look for extra detail in the “Notes” section when provided by the manufacturer. For example, Note 5 says, “On power-up, last four faults, if any, will be flashed on Red Led.” Even if the customer has tried resetting the board, the faults have not been lost. Good to know!

If the unit has a user interface, often the scrolling details will be found on the wiring diagram sticker in lieu of lost paperwork.

Some manufacturers may provide QR codes in their leave-behind literature or on the unit’s cabinet. Scanned with a code reader using a smart phone with internet access, the technician has access to a website containing technical information along with videos about installation, servicing and troubleshooting techniques.

Get Help using new Technology

Manufacturers will often have a field service representative or engineer visit a site for a variety of reasons. Sometimes it’s to monitor the start-up of a new product or to assist a new contractor with installation and commissioning procedures.

Too often, however, it’s because a unit has failed completely or experiences intermittent failures that rarely ever occur while the technician is on site and a telephone technical help session did not resolve the issue.

If a site visit is going to happen, it’s usually the result of one or more tech calls and can go one of several ways, for example: • Some site visits are resolved quickly. The offending issue may be unknown to an inexperienced technician or something was overlooked.

• Sometimes, it’s an equipment specification error (wrong unit for the job) or improper installation.

• Often, one or more technicians have made several service calls to the unit each trying different remedies that fail to resolve the issue.

• Remembering that the end-user, especially a residential customer, has suffered tremendous inconvenience, even missing work, the atmosphere may be tense and very uncomfortable for all.

• Sometimes the end-user refuses to allow the original servicer to attend so that the manufacturer’s representative needs to find another contractor willing to get involved.

• Site visits typically involve some expense; sometimes an equipment buy-back is the only remedy; sometimes the contractor is on the hook for mistakes; sometimes the end-user made unauthorized modifications; and sometimes the issue goes to small claims court.

• In short, intermittent, perplexing issues don’t fix themselves. When in doubt, get help.

HIERARCHY OF HELP When a technician crosses paths with a unit that he or she is familiar with but is doing entirely unexpected things, or a tech encounters a completely unfamiliar unit that isn’t working, a time sensitive repair often brings untold anxiety for the technician. But the cruel fact is this: you’re on your own!

“Praemonitus, praemunitus” an old Roman proverb means that having knowledge in advance helps one to be prepared.

True enough, no one can possess or retain enough HVAC knowledge to suit every instance; however, knowing who to call and where to look for help is of paramount importance.

I took Maslow’s Pyramid of Needs and inverted it into a reverse hierarchy as a guide for technicians or installers looking for resources to guide them through a jam (Figure 2).

and experience to gather good data: what’s the unit doing or not doing, are there any unusual noises, erratic operation and so on. Have these details ready to relate to your contact person.

Social media, in my view, is the last place one should look for immediate help because it’s simply too hard to sort through all the misinformation found on platforms such as YouTube and Facebook. While there may be techs who have established top-drawer links on social media, I’m not ready to endorse a random YouTube search.

Some of these videos are not grounded in appropriate industry standards; i.e. they demonstrate risky and dangerous practices and must be avoided.

BUILD YOUR KNOWLEDGE BASE I haven’t been in the field for many years, but I still do some research about HVAC topics every week. There is so much to know, but my focus is on building a repertoire of strong HVAC voices so that I’ll have a place to start my searches.

Here’s a short list of some bona fide resources that I value: • Of course, HPAC magazine! Be sure to visit HPAC’s booth at the CMPX show.

• HRAI, Canada’s premier HVAC education organization.

• Appropriate Designs, hydronicpros. com is John Siegenthaler’s website “dedicated to advancing the science and proper application of modern hydronic heating.” John is also a regular contributor to HPAC magazine.

Figure 2.indd 1 • Robert Bean, healthyheating.com. Is there an HVAC topic Robert hasn’t covered from the engineering side?

• Dan Holohan, heatinghelp.com. Dan is a long-time HVAC educator, steam heating system guru and he tells some great stories about the industry.

• Allison A. Bailes III, PhD, energyvanguard.com. Allison provides detailed information about HVAC in tight housing, duct design, zoning and heat pumps.

Use your wits, training, experience, test tools; gather data Locate and utilize documentation: writing diagrams, comissioning reports, installation criteria, sequence of operation, building management system, stored data, QR codes

Most likely ways to get help quickly

Call a colleague, service manager, boss; text messages, iMessage, WhatsApp or new technology like XOI collaboration for smart phones Call local wholesaler, parts counter, sales office; inquire about TSB’s, documentation, connect with tech support If possible, utilize manufacturer websites: DaveNet, Comfortsite, UPGnet, HVAC Partners, etc.

Build Knowledge base: training sessions, podcasts, manufacturer videos and apps

Social Media: Facebook, YouTube LinkedIn

More time-consuming methods, also useful for adding to knowledge base over time

Figure 2. Resource hierarchy for technicians or installers looking for help.

• Bryan Orr, hvacrschool.com. Bryan’s focus is primarily on residential cooling topics since he’s based in Florida, however, the information provided is top drawer for technicians and installers everywhere. Sign-up for his Daily Tech Tip and listen to his podcasts.

• Gary McReadie, hvacknowitall.com, is a true-blue technician and budding influencer working on mainly commercial equipment in the GTA. Gary produces short videos on subjects ranging from how to use specific tools to how to become an HVAC tech. He’s on several social media platforms and produces an hour-long podcast on a regular basis. Gary is at the CMPX show.

• This manufacturer website, climate. emerson.com, is all about Copeland compressors, including information about training and tech support along with a helpful tools and a resources link.

• CMPX Trade Show: I know many HVAC technicians will be too busy or are too far away from the GTA to attend this time around. However, it does make sense to have at least one person from a given shop, such as a lead technician or service manager, make the trip. This is the best time to concentrate on garnering important relationships. Visit the various manufacturer

booths, ask for the technical manager or field representative’s business card, find out who to call when the going gets tough. And, yes, there will be salespeople there too: never discount a sales rep’s ability to help with technical issues. Remember, nothing happens until a sale is made, so be sure to treat the hard-working HVAC salespeople like the great assets they are.

Also, provincial organizations such as The Ontario Refrigeration and Air Conditioning Contractors Association along with the UA Local 787 educate workers through the Joint Training and Apprenticeship Committee (JTAC), a huge knowledgebase for unionized technicians.

I have only touched on a few resources, there are plenty more. Some say that “life is a process of learning, forgetting, and then learning again.” That’s certainly true of HVAC life! Thus, getting help starts with the technician and his or her ability to call upon a personal database of stored knowledge. Remember: Forewarned is forearmed. <> Ian McTeer is an HVAC consultant with 35 years experience in the industry. He is a refrigeration mechanic and Class 1 Gas technician.

Wi-Fi networks are getting stronger because the devices are working together to deliver the messages. BY CURTIS BENNETT

G

etting your wireless signal to make it to its final destination is getting easier every day. Mesh networks are all the rage, you hear it almost as a term that people drop to sound cool. I do it. Seriously, I do.

“Oh you are having Wi-Fi- issues?

Have you heard of mesh networks?”

It’s funny for me because most of my friends and family don’t really know what I do, and I sort of like it that way.

They know I do “technical stuff” so I can dazzle them with these little tidbits of technical jargon.

Networks have been designed for a long time now. There are also many different kinds of networks. The reason for any network is to connect devices.

This may be a computer, IoT devices, cars or anything that we would like “connected” together.

The dictionary say’s a network is “a group or system of interconnected people or things.” We use the word network

54

HPAC | MARCH 2020

for many different things. We even refer to it when we are “networking,” which basically means meeting people and introducing yourself—30 years ago this was simply the meaning of being polite.

Anyways, we use networks to extend the capabilities of single devices. Think of it like this, your computer (or whatever device we are talking about) is a car. If we only had one road that went from your house to your mom’s house, you could only ever visit your mom. But if we had a network of roads you could go anywhere you needed to.

Now I know that is a little over simplified, but that is the basis of a network.

A network extends our capabilities beyond just a simple back and forth one direction of data flow.

Ok, funny story time. And yes it’s about me being electrocuted. It has to do with “extending my capabilities.” So in the early 1990’s cordless phones were just getting big. I bought one with my own

money in grade 12, but the signal strength back then on these phones was not near as good as they are now. At the time, my girlfriend (now my wife) and myself would talk for hours. The problem was I had to be within the range of the base to get the phone to work properly.

The base was upstairs, and my room was downstairs. This created a problem for me eventually. So me being the super bright do-it-your-selfer, I decided to put the base in my room. There was only one issue. I did not have a phone jack to plug it into. So I needed to extend the wires from the phone jack in my brother’s old room, to mine. Should be simple I thought, get some phone wire from somewhere and extend it under the stairs and, voila.

Well I was cutting a few corners, and one of them was to not use wire strippers. Phone lines work off a weird voltage, 48VDC, which normally is not an issue, but if you are stripping both the HPACMAG.COM

WHAT A MESH!

Different types of networks.

wires with your teeth it is!

It was a really good one, the shock I mean, because apparently saliva is a good conductor! You think sticking your tongue on a 9V battery hurts. So lesson learned that day.

There are a few different types of communication networks, but I want to focus on the one that literally is building our world as we know it. The mesh network. A mesh network works by allowing each device to independently repeat the information it receives to other devices in the network.

Why this is important is that network devices are not always at even spacing, especially wireless devices, and the communication from one device to another may stop because it cannot reach. In the case of a mesh network the information can get routed though many devices, not in a “straight line,” until it finally gets to the intended device.

Think of it like this, we have a room full of people and I need to get a note to the person way at the back. I can do two things: I can fold the note into a paper airplane and try to throw it to him, which I doubt would work, or I can hand it to the person beside me and he hands it to the person beside them and so on, each person understanding that we are trying to get the note to the person at the back of the room.

If it was just me and the person at the back of the room in the room, I could never have gotten the note to him. But because the room was filled with other people, they helped get the message delivered. This is why mesh networks are so powerful and very handy.

If, in this same scenario, there were a few people that got up and left in the middle of me trying to get the note delivered, the note would have just taken a different path. It does not have to take the same path every time. The goal is to get the note delivered. So mesh networks have the ability to “self-form” as well as “self-heal.”

I started using mesh networks about 15 years ago with the onset of ZigBee, one of the first protocols to use mesh networking. It has the ability to route information to get the data to the intended “node.” A node is just a device in the network.

Back then mesh was a very powerful tool. Wireless was just starting to take off, and Wi-Fi was not being used in this way.

But this type of network always created an issue. You needed two different protocols to get the information into the hands of the user. The ZigBee, or other mesh networks, would gather the information from the environment using arHPACMAG.COM

rays or devices, for example they could be collecting temperatures from all over a building. All of these temperatures would travel to some central location to then get changed into an “Internet” protocol. This means the information would have to be reformatted so it could be put out on the web, or transferred between computers or over Wi-Fi. Here-in lies the problem, we are collecting the data with one protocol, but transmitting it to the world with another.

Is there something that can solve this? Yes of course there is. The Wi-Fi mesh network.

Wi-Fi mesh networks are going to change the way we gather data. Now we don’t need any central gathering station to reformat information. We can go straight from the device out to the world. This is done by not having the end devices creating the mesh network, but creating a mesh network “around” the devices.

This way the end devices, in our case the temperature sensors, don’t talk with each other but they communicate directly with the Wi-Fi network. But the temperature sensors don’t have to always talk to the same Wi-Fi device. It’s the same premise as the note passing in the room. The Wi-Fi mesh network will decide how to get the info delivered most efficiently.

With the onset of IoT the Wi-Fi mesh becomes pivotal to retrieving and pushing information out to the world. There are going to be so many devices in your house or building that we will need to make sure the delivery is as efficient as possible.

This also helps developers, as now they don’t have to deal with more than one protocol. You have probably seen Wi-Fi extenders in your house our office, and that was the start, but now with mesh networking the possibilities for information gathering is huge.

Mesh networks are, in a couple words, “very cool.” So now you can drop that word around to your friends and family and actually know what it means. <> Curtis Bennett C.E.T is product development manager with HBX Control Systems Inc. in Calgary.

AMVIC INSULATED PEX PANEL; HYDRONIC RADIANT FLOOR HEATING SYSTEMS

DESIGN Amvicâ&#x20AC;&#x2122;s insulated PEX panel combines a number of unique elements making it one of the best panels on the market. The panel consists of expanded polystyrene insulation, moulded to high impact polystyrene film. This combination makes for a stronger, more resilient interlocking PEX panel. Additionally, the panel nubs form a mushroom shape, locking the PEX piping firmly in place.

Once inserted, it guarantees that the pipe is properly positioned and seated in the panel.

The innovative panel design with bridging and cavities ensures that the PEX tubing will be completely surrounded with concrete and not pushed to the bottom of the panel. This feature will allow for better heat distribution from the radiant tubing and a more efficient energy transfer.

CONTRACTOR SAVINGS The design of the Amvic PEX insulation panel makes for a very durable and simple install on the job site. Because of its strength and stability, contractors can handle the material with ease eliminating breakage, replacement and additional labour. The film on the panel along with the nubs, allows the PEX tubing to be walked in and locked into place, rather than constant bending to wire-tie or staple the tubing firmly into place cutting labour time and material costs. The oversized four sided tongue and groove interlock system makes installation quick, easy and secure. The size of the panels also increase productivity and precision when placing the panels on the floor. The 2x4 panels become easier to maneuver, easier to place and easier to identify leveling inconsistencies.

APPLICATIONS Hydronic heating can solve winter season problems by implementing a snow and ice melt system by circulating warm liquid through PEX tubing which is concealed in the concrete. These systems can be easily installed in residential, commercial or industrial applications such as driveways, sidewalks, stairs, entrances, parking lots, ramps, helipads and much more.

Homeowners can choose to have hydronic heating throughout their entire home which can eliminate the need for forced air units and reduce utility bills. Common living areas for floor heating include the bathroom, the family room, the garage/driveway, entrances and even the kitchen.

COMPRESSORS THROUGH THE YEARS An overview of how compressor technology has been making strides in both operational and energy efficiency. BY DAVE DEMMA

Twin Carbondale two-cylinder compressors in the old Winterland Arena.

I

grew up in Northern California and was of high school age during the late 1960’s. While there were many things unique to that time period, the creative explosion in popular music was unparalleled: The Beatles, Cream, Jimi Hendrix, The Stones, Deep Purple, Jefferson Airplane, Joni Mitchell, The Doors, The Kinks, King Crimson, Neil Young, … I could go on.

All of these acts would have made stops in the San Francisco area, performing at one of the many concert venues, including the Winterland Arena. You might be thinking, “Curious name for a concert venue.” Indeed, a very curious name.

Originally opening in 1928 as The New Dreamland Auditorium, in the late 1930s the building was upgraded with a “modern” refrigeration system providing the cooling capacity for a newly installed ice-skating rink.

In 1966, legendary rock promoter Bill Graham began using Winterland Arena as a concert venue, and the rest is history.

But what does this have to do with compressors? While working as a refrigeration technician in the San Francisco area in the mid-1970s, the company I was employed by received a call from the caretaker at Winterland Arena. He was concerned by the presence of the very distinct odour of ammonia in the building.

Having attended several concerts at Winterland, I was excited about seeing a different side of the venue, including what could be considered as museum-worthy refrigeration equipment. I gladly took the service call.

The artful Carbondale gauge plate.

As this was long before the advent of digital cameras, I took the opportunity to swing by my house and pick up my camera, wanting to capture the day’s events on film.

The caretaker greeted me and offered a tour of the old building, showing me the dressing rooms, reception areas, the backstage area, and all the while sharing anecdotes from various concerts and music groups. He even gave me a guitar pick that belonged to Stephen Stills. From the upper balcony, which overlooked the stage below, you could almost hear the ghosts of concerts past in the complete dead silence of the empty arena.

After the tour we finally made our way to the fully intact ammonia chiller from the 1930s.

Above is a photo of the compressor room, showing twin Carbondale two-cylinder compressors, driven by open frame synchronous motors. These compressors were large bore/ large stroke, depending on the capacity, anywhere from 6-in. x 6-in. to 10-in. x 10-in.

Given the huge piston mass and large stroke, these machines typically operated between 300 to 400 RPM. Barring any serious system-related issues, the low compressor RPM allowed these beasts to operate relatively trouble-free for years.

Those compressors, while not brand new, still struck me as an example of machinery as art. But the item that really caught my eye was the gauge panel (pictured above). Given that the system was no longer in use, I did my best to persuade the Continued on p60 HPACMAG.COM

caretaker to let me remove the gauge panel, as it would have made a stellar addition to my collection of equipment artifacts.

But alas, he wouldn’t agree to that. It is an absolute thing of beauty, representative of craftsmanship from a bygone era.

So, what is the point of this stroll down memory lane? It gives some perspective to the advances that have been made in compressor design, and particularly compressor efficiency.

Somewhere I have a copy of an ad from the York Ice Machinery Company (as they used to be known), showing the contrast in size between a 6 x 6 compressor and their “new” semi-hermetic reciprocating compressor. Not only was the motor fitted inside the compressor body, but the small diameter pistons and reduced piston stroke allowed the compressor to operate at a much higher RPM. This allowed this relatively “small” compressor to have the same Btu capacity as the gargantuan 6 x 6. This design also eliminated the need for a compressor shaft seal, which was a potential leak path. It also eliminated the need for drive belts, motor to compressor alignment and periodic motor bearing lubrication.

That was just a first of many in the evolution of compressors. Below are a few more.

Figure 1. Comparison of a reed valve plate and a discus valve plate in piston compressors.

Figure 2. Scroll compressors, a more efficient compression cycle.

DISCUS VALVE PLATE

SCROLL COMPRESSORS

Piston compressors, by their nature, have a built-in inefficiency. Since volume is proportional to pressure, as the piston travels upwards during the compression stroke, the resulting reduction in cylinder volume causes the vapour pressure to increase. The cylinder volume would have to be reduced to zero for all of the compressed vapour to exit the cylinder. This is not possible, as there is some volume resulting from the clearance between the top of the piston and the bottom of the valve plate, along with the volume resulting from the discharge port in the valve plate, which means that some vapour remains at top dead center of the compression stroke.

This volume is known as “clearance volume.” Before suction vapour can enter the cylinder during the intake stroke, some portion of piston travel is necessary to re-expand the clearance volume vapour. And, that portion of piston travel dedicated to re-expanding the clearance volume vapour provides absolutely no tangible work. So, the as the discharge pressure increases in relation to the suction pressure (compression ratio), or as the clearance volume increases, the compressor capacity reduces.

Figure 1 shows comparative photos of a reed valve plate and a discus valve plate. The discus valve plate eliminates the discharge port in the valve plate, as the discus discharge valve is completely flush with the underside of the valve plate, thus eliminating a portion of the clearance volume vapour that has to be re-expanded during the intake stroke.

Production of scroll compressors started in 1988. While they operate on the same basic principle as a piston compressor—in that there is a proportional relationship between pressure and volume, and reducing the vapour volume results in an increase in pressure—the scroll has one distinct advantage, the action produced by the rotating scroll plate moving against the fixed scroll plate results in the volume where suction vapour enters the scroll set being reduced to zero prior to the compressed vapour exiting the centre discharge port.

Hence, there is no re-expansion of high-pressure vapour (figure 2). The compression cycle is 100% efficient.

Compressors are selected based on design conditions for a particular application. Those conditions constitute the worst case scenario where the greatest amount of capacity is required. For refrigeration applications, these include periods after defrost cycles, warm product being loaded into a refrigerated space and high ambient temperatures in summer.

When the actual load conditions are less than the design condition, the compressor capacity would be greater than required. As such, without some means of operating at a reduced capacity, the compressor not only provides capacity greater than required, but the electrical consumption is in excess of what is necessary. Technology improvements have been made to address the standard compressor’s inability to match capacity with the load.

COPELAND DIGITAL SCROLL The Digital Scroll differs in design from the standard scroll in that it has the ability to allow the top scroll plate to “lift” approximately 1-mm from its normal position. This is enough to completely eliminate the scroll plate’s ability to compress vapour. The result is 100% unloading capability.

This is where the “digital” part comes in. Through the abilities of electronic controllers, the compressor can now operate in segments of “cycle time,” which is comprised of the sum of “loaded state cycle time” and “unloaded state cycle time.”

Plainly speaking, the compressor operation can be broken down into cycles of 20 seconds, with some portion of the 20 seconds operating completely loaded, and some operating completely unloaded.

The capacity of the digital scroll can vary between 10% and 100%. The compressor capacity can be calculated from a ratio of percentage of loaded state time to the total cycle time. For example, if the loaded state time were 10 seconds, and the total cycle time were 20 seconds, the compressor capacity would be 10/20, or 50% of total capacity.

Given the wide range of capacities the digital discus can operate under it can offer a very precise solution for matching the compressor capacity with the system load. Not only can design parameters be maintained more closely, but there is the added benefit of an opportunity for energy savings.

DIGITAL DISCUS The same technology that allows a scroll compressor to operate loaded anywhere from two to 20 seconds for each 20 second cycle time has been applied to Copeland’s discus compressors as well. The unloading is accomplished by blocking the suction port of the given cylinder to be unloaded.

This will allow the bank of cylinders controlled digitally to operate anywhere from 10% to 100% capacity.

If it’s a three-cylinder compressor (3D model), the three cylinders will constitute a single bank of cylinders and will load or unload simultaneously. The four-cylinder (4D model) and six-cylinder (6D model) compressors will have one bank of cylinders that remain 100% loaded at all times. As such, the 4D will unload down to 50% and the 6D down to 33%.

A benefit of the semi-hermetic compressor, with removable heads and valve plates, would allow one to upgrade a standard discus compressor to a digital discus compressor. If capacity modulation is required, this is a simpler and less expensive solution than replacing the compressor.

VARIABLE FREQUENCY DRIVES Another option for providing compressor capacity modulation is to apply a variable frequency drive (VFD) to a standard compressor. A VFD converts the input current to direct current, 64

HPAC | MARCH 2020

and from this generating a simulated AC signal at varying frequencies. Varying the frequency will vary the motor speed, thus varying the compressor capacity.

While VFDs can provide good compressor capacity modulation, there are several things that must be taken into consideration. Most VFDs are capable of generating frequencies from 2.5 Hz to over 300 Hz. This is well outside the normal range for the typical compressor motor, so the frequency upper/lower limits must be kept within the compressor manufacturer’s recommendations.

In addition, the frequency range (ultimately determining the motor speed) will be dependent on the compressor’s ability to provide proper lubrication at the reduced speed. Again, the VFD must be set up based on the compressor manufacturer’s specifications.

An additional advantage of a compressor outfitted with a VFD is that the startup frequency results in a low motor speed/torque, which reduces the normal high startup current.

Not only does this reduce electrical consumption, but the low torque start relieves stress on the motor/compressor.

INVERTER DRIVEN COMPRESSORS This is what mini-split/multi-split/VRF equipment manufacturers have been providing with their equipment for some time. In simple terms, this as a compressor (rotary or scroll) with a builtin VFD. So it’s not too much different than a compressor with an aftermarket VFD. But there is the benefit of the manufacturer spending the necessary R&D to design the inverter components for optimal performance of their compressor.

The thrust of this article was to simply make the reader aware of the current technologies that are being used to modulate system capacity (or compressor capacity) to meet the actual load at any given time. Certainly, each method could be explored in greater depth to delve into the technical explanations of how/why each method is employed, how they operate, methods for troubleshooting, etc, but that is for another time.

Bottom line, there are options available to match equipment capacity with load and provide maximum comfort (air conditioning) or product integrity (refrigeration) without having your pedal to the metal when the equipment is operating.

PHOTO COURTESY AHR EXPO

ndustry professionals flocked to the warm climate of Orlando, Florida for the 2020 international Air Conditioning Heating Refrigerating Exposition (AHR Expo) held at the Orange County Convention Center, February 3-5.

The expansive show floor hall spread across 506,090 sq. ft., and exceeded last year’s event in Atlanta with respect to the number of visitors and exhibitors, welcoming over 50,000 attendees and 1,900-plus exhibiting companies.

While it was a long walk from one end of the show floor to the other, the aisles were active with engaged visitors asking plenty of questions and eager exhibitors supplying the answers.

“The energy on the show floor this year was hard to miss. From corner to corner, in every booth, education session, event program, everywhere, it’s clear that this industry is alive and thriving,” said Mark Stevens, show manager, after the event. “Leading in to this show we knew there were some big changes happening across the industry and we saw that reflected in Orlando. It is truly an exciting time to be a part of the HVACR community and, if 2020 is any indication, it is just getting started.”

General observations on the trade show floor and from the educational session topics revealed recurring themes of smart buildings and energy efficiency solutions.

This year’s education program included over 200 sessions, many inspired by industry trends including how to tackle the skilled labour shortage, explaining the changing refrigerant landscape, moving towards a post-carbon world and dealing with climate change initiatives at all levels of government. While changes are imminent for the industry, most sessions urged

This year's show in Orlando attracted over 50,000 attendees.

attendees to recognize the opportunities and get out in front of the change.

While the list of new technology enhancements was extensive, again the drive for efficiency in all sectors leads the way. Along that theme, AHR presented the 2020 Product of the Year honour to Danfoss for its CO2 Adaptive Liquid Management (CALM) solution, a complete solution that can improve the energy efficiency of transcritical CO2 refrigeration systems by as much as a 10 per cent.

The overall 2020 Product of the Year winner was selected by a jury of ASHRAE member judges from among the 10 different product category winning products chosen as AHR Innovation Award Winners in the Fall of 2019 (revealed in the Dec. 2019 issue of HPAC).

“It’s truly an honour to have been recognized by the industry for our deep commitment to engineering next-generation solutions that are both energy efficient and environmentally friendly,” said Peter Dee, food retail sales director–

North America, Danfoss, in a release.

“The CO2 Adaptive Liquid Management solution represents yet another step toward helping food retailers around the world—no matter the climate zone or store size—make the transition to lowGWP refrigerants while saving energy and costs, maintaining system reliability, and ensuring food safety.”

As a sign of growing interest in the Awards and continual product development, the Innovation Awards received the most entries ever this year in its 17 years of existence.

“If the 2020 AHR Expo is any indication of where HVACR is headed, this industry is on the path to exciting things,” said show manager Stevens. “We look forward to following along as we head into the 2021 show in Chicago.”

TRENDS IN WATER HEATING

BY ROBERT WATERS

W

ith 2020 upon us there are several emerging trends that are affecting the water heater industry. In the past I have written about emerging water heating technologies (HPAC, May 2016) where I focused on the technical details of different water heater types. In this article, I will focus more on the regulatory factors that are influencing the Canadian water heater market.

Harmonization of Canadian regulations with those in the U.S. has been a primary focus for the Federal Government over the last several years. The Natural Resources Canada (NRCan) Energy Efficiency Regulations have been updated for many products to match the requirements of the U.S. Department of Energy (DOE) regulations. On October 31, 2018 NRCan published Amendment 14 to the Energy Efficiency regulations, and while it did not contain any new water 68

HPAC | MARCH 2020

heater energy efficiency requirements, it did harmonize the testing requirements with those of the U.S. This has impacted the way water heater efficiencies are now communicated and reported, with the new Uniform Energy Factor (UEF) test requirement replacing the old Energy Factor (EF) test. The UEF test was adopted by the DOE in June 2017 and has been law in the U.S. since then.

The UEF test procedure has been designed to simplify the water heater selection process for consumers and to encourage water heater manufacturers to design energy efficient water heaters to meet specific applications.

UEF makes it easier to compare one appliance to another by separating water heaters into categories (called bins) based on hot water usage rates. UEF ratings are determined by assigning water heaters into one of four different usage bins and then evaluating their

performance based on that usage. The four bins are expressed as either small, low, medium or large. The previous EF test method subjected all water heaters to the same simulated use amount regardless of water heater size. This made it difficult to do apples-to-apples efficiency comparisons between different water heater models when looking at the EF rating.

With UEF testing, the usage bins are based upon the water heaters first hour rating (FDR), which is the amount of hot water the unit can provide in one hour of operation starting with a full tank of heated water. FHR will vary based on the capacity and the heating input of the tank.

By basing the rating on the FHR, the UEF test reflects a more real-world picture of what a homeowner can expect, and it allows for easier efficiency comparison with comparable sized models.

Similar to EF ratings, the higher the HPACMAG.COM

UEF rating the more energy efficient the water heater is. A water heater’s UEF rating should only be compared with water heaters within the same usage bin. For example, a high bin water heater with a UEF of 0.95 does not perform exactly the same as that of a low bin water heater with a UEF of 0.95.

In Canada all residential water heaters must now display their efficiency with an UEF rating, and any new products must be tested with the UEF test procedure. UEF ratings will now start appearing in manufacturer’s literature and there will be new EnerGuide labels on water heaters.

The new EnerGuide label will show the efficiency expressed in UEF, and it will also show which of the four usage rate bins the tank falls into. Each bin will have a unique minimum energy performance standard (MEPS) efficiency requirement.

Existing products that have already been tested using the existing energy factor (EF) test procedure can still be sold, but they must use a formula to calculate an equivalent UEF rating.

Commercial water heaters will not use UEF ratings as they are subject to different rules and regulations and will typically express their efficiency in terms of thermal efficiency %.

Another trend emerging in the water heater market is the gradual rise of gas-fired condensing technology, for both storage tank and tankless type water heaters. For tankless units the condensing market recently got a big push forward as new NRCan Amendment 15 Energy Efficiency regulations kicked in on January 1, 2020.

Now all residential tankless water heaters <200 MBH input must be condensing technology. Minimum efficiency regulations will be based on the products maximum flow rate: 0.86 UEF for <6.4 L/min and 0.87 UEF >6.4 L/min.

Starting on July 1, 2023 commercial units >200 MBH input will also require all condensing technology with efficiency regulations of minimum 94% TE. At this time there currently are no HPACMAG.COM

New UEF usage rate bins.

“For tankless units the condensing market recently got a big push.”

NRCan regulations that require storage tank water heaters to be condensing technology. This is likely to change in the next few years as NRCan have expressed aspirational goals to get to condensing level for all water heaters by 2025. We’ll have to wait and see if and when this happens.

For now there are growing markets for condensing products in Ontario and B.C., but due to quite different reasons.

In Ontario, condensing water heaters are being mandated for some new homes to meet the requirements of the Ministry of Housing’s Energy Efficiency for Housing Supplemental Standard SB12. Several of the most popular compliance packages in SB-12 require that

water heaters must be condensing, and this has certainly increased the usage rate of condensing water heaters.

In B.C. the market is being spurred forward with a softer, more voluntary approach. The gas utility, FortisBC, is currently incentivizing the market by offering rebates of $1,000 for water heater retrofits that utilize storage type or tankless condensing water heaters.

Outside of these regions non-condensing storage water heaters are still the primary products being installed.

Condensing units continue to be a tough sell due to much higher costs.

Condensing storage water heaters are typically about double the cost of a non-condensing water heater, and also require significantly more labour due to additional installation requirements with venting, piping and condensate disposal.

Incentive programs like those in B.C. help to reduce the sticker shock for condensing equipment, and the market for condensing water heaters across the country should continue to grow if more gas utility companies introduce these types of incentive programs.

The last trend to look into is the drive towards electrification that is happening in some areas of the country. Climate change issues are coming to the forefront frequently, with some jurisdictions declaring climate emergencies and starting to look at ways to eliminate fossil fuel equipment completely.

Vancouver and Toronto both declared a “climate emergency” in 2019, and are both looking at ways to reduce greenhouse gas emissions from all sectors, including from space and water heating equipment. In Vancouver, as part of the city’s “Climate Emergency Response Report” from April 2019, they have adopted a new target that will require all new and replacement heating and hot water systems to be zero emissions by 2025. To meet this target Vancouver expects heat pumps to be an important solution in the transition.

Example of a condensing tankless water heater.

Example of a condensing storage tank water heater.

On the federal level, in 2018 NRCan published its aspirational goals for market transformation for space and water heating technologies. The long term goal for 2035 is for all water heating technologies for sale in Canada to have an energy performance of greater than 100%. To meet this long-term aspirational goal all water heating technologies would need to achieve a performance equivalent to that of a heat pump.

As you can see, there are high expectations for heat pump water heaters (HPWH) by policy makers. HPWH’s have been around for some time, but the market for them in Canada is growing very slowly.

It is safe to say the market is past the experimentation stage, but widespread adoption is nowhere close. There are still hurdles for HPWH’s to clear before they become more widely adopted.

The two primary issues are the concerns about operating HPWH’s in cold climates, and the high initial cost of the equipment. HPWH also have slower recovery rates compared to gas WH technology, and increased space requirements which may make them less suitable for some applications.

There are lingering concerns about the suitability of HPWH’s in Canada’s cold northern climate. When the HPWH is installed in a heated building it draws room air into the unit and uses the heat pump refrigeration cycle to heat the water in the tank. The room air gets cooled and pushed back in the space where it must be reheated by the space heating system. This reduces the overall efficiency of the unit in winter months and leaves some questioning “are heat pump water heaters worth it?”

To help answer this question there are several NRCansponsored pilot programs currently running across Canada in 72

B.C., Nova Scotia, New Brunswick and Manitoba. These HPWH pilot programs have installed both integrated units and split CO2 heat pumps to evaluate their performance and savings potential. When these pilot programs are finalized, there will be hard data available to help answer the question above.

HPWH’s typically cost almost four times more than a conventional electric resistance water heater. However the energy savings from a HPWH can be substantial due to their extremely high efficiency. With UEF’s as high as 3.7 they will use much less energy than a conventional electric water heater which typically has a UEF in the 0.93 range.

In areas with high electrical costs this can make a HPWH a product some will consider. But with electricity costs substantially more than natural gas, the likelihood of someone voluntarily switching a gas fired water heater to a HPWH is very slim. So if the drive to electrification continues, governments can expect push back from consumers who will see their costs increase dramatically.

As 2020 begins the water heating market in Canada is evolving with new regulations, climate change concerns and government policies. What will be the dominant types of water heating equipment installed in Canada in 2030? I’ll have to get back to you on that. <> Robert Waters is president of Solar Water Services Inc. which provides training, education and support services to the hydronic industry.

< MSN “With this new feature, Nest is learning how to identify unusual patterns related to your HVAC system, and can alert you to a variety of potential issues,” explained Jeff Gleeson, product manager for Google Nest, in a company release.

Nest will learn to detect potential HVAC issues by monitoring the system’s patterns, historical data and current weather.

For instance, if it’s taking longer than normal to heat your home, there might be a problem with your heating system—even if you haven’t noticed anything. There will be issues that your thermostat won’t catch— but over time and through your feedback, Nest thermostats will get smarter and better at detecting more and more possible problems.

“Most of us don’t have an HVAC pro on speed dial,” Gleeson said. “So we’re also testing out the ability to help customers connect with a professional who can help, starting in select cities.”

The Handy-integrated platform will connect Nest users with HVAC professionals to make troubleshooting potential system issues easier for the customer. Booking through Handy will initially be available in upwards of 20 U.S. cities, including Atlanta, Boston, Denver, Las Vegas and San Diego.

SMALL FOOTPRINT. BIG IMPACT. HVAC systems are key to comfort and energy savings in buildings, but until recently, choosing one meant sacrificing the other. Today, you can maximize both with a Hitachi VRF Sigma System.

Designed to address climate needs both indoors and out Hitachi VRF Sigma Systems are engineered to provide years of reliable performance while reducing power consumption, wear and tear, and noise. The result is whisper-quiet, personalized comfort that is easy on the pocketbook and the planet.

The carbon footprint isn't the only thing that's small Outdoor units are compact and lightweight, making transportation and installation a breeze. Maintenance is fast and simple, too, with a smart design that enables easy access.

And little is required beyond filter changes and coil cleaning for a smaller lifetime investment.

Partners you can count on Hitachi VRF Sigma Systems are offered in Eastern Canada exclusively through The Master Group.

When you purchase a Hitachi solution, you will benefit from working with two of the most respected names in the HVAC industry: The Master Group, the largest independent HVAC-R distributor in Canada, and Johnson Controls-Hitachi, a leading global brand for HVAC equipment and controls.

Count on our teams to stand behind these exceptional systems with unparalleled service and support every step of the way.

Learn more at www.hitachiaircon.com WARMING THE BUILDING NOT THE PLANET Energy-Efficient HVAC Technologies Help Address Climate Challenge The Canadian government has committed to decreasing the country's carbon footprint by reducing dependency on fossil fuels and lowering emissions. The HVAC industry can play an important role in this effort: In Canada, buildings produce 17% of greenhouse gases, in large part due to the fossil fuels used for heating and cooling[1]. Energy-efficient Variable Refrigerant Flow (VRF) systems can be installed in both new and retrofit projects, helping to address this problem.

Ductless VRF systems provide significant energy savings by virtually eliminating the energy loss associated with ductwork that occurs in traditional HVAC systems. In fact, Hitachi VRF Sigma Systems are estimated to save up to 39% over conventional systems. Further, VRF systems provide zoned heating and cooling, enabling energy savings in unoccupied areas. And they can be sized to meet current needs exactly while easily accommodating future expansion. VRF systems are a proven technology widely used throughout Europe and Asia. As the country works to meet its climate goals, VRF systems, such as Hitachi VRF Sigma, are a ready solution that can help make Canadian buildings more energy-efficient.

LIBERTY PUMPS

PRESENTED BY

PROVORE® GRINDER PUMPS Grinder technology is advancing and Liberty Pumps is at the forefront of evolving sewage pump performance. The new ProVore® grinder from Liberty Pumps is designed for use in residential applications where an addition of a bathroom or other fixtures below sewer lines requires pumping. It features Liberty’s patented V-Slice® cutter technology utilized in its popular Omnivore® series of 2 hp. grinder pumps. This proven cutter design easily shreds solids - such as feminine products, rags and other unwanted debris. The new ProVore® brings this advanced technology down to a more cost effective residential level. Powered by a 1 hp. motor, this smaller grinder is designed to operate on a standard 115 or 230 volt circuit – requiring only a 20 amp breaker. No special wiring, as is necessary with larger hp. grinder pumps, is needed.

The pump comes with a 2" vertical style discharge (common on solids-handling pumps) and a standard leg pattern matching Liberty’s LE-Series. This allows for an easy retro-fit into already existing systems. Engineered with flow rates to 46 GPM – the ProVore® provides adequate scouring in 2" discharge lines with lower pumping heads commonly found in residential basement installations.

Compact factory assembled systems are available in both simplex and duplex versions. The ProVore®380 uses Liberty’s very popular PRO380 basin. This system features Liberty’s QuickTree® technology for easy field service of the floats without removing the cover or disconnecting the plumbing.

A quick-removal access cover and heavy-duty integrally molded gaskets are also features found on this system. In addition, Liberty has just launched the new ProVore®680 – a compact duplex version of the 380. Standing only 24" tall, this small profile duplex system utilizes two ProVore® pumps for uninterrupted service. An advanced pump controller is included with the system to alternate pump operation and provide an alarm to the homeowner in the event of a failure.

Whether it’s a traditional solids-handling pump or a newer style grinder, Liberty’s broad offering of products can satisfy a variety of pump applications, and with its aggressive product development strategy, you can be assured Liberty will continue to meet the needs of today’s rapidly evolving market.

Mitigating Risk for Supermarket Retailers in a Regulation Environment Speakers: Andre Patenaude, Emerson Commercial and Residential Solutions; Sandy MacLeod, HRAI The phase-down of HFCs remains a focus of environmental regulations around the globe. For example, the 2016 Kigali Amendment to the Montreal Protocol calls for a gradual phase-down in both the production and consumption of HFCs by more than 80% over the next 30 years. To date, 92 countries have backed this initiative including Canada.

Some international and regional initiatives are taking a more aggressive approach toward meeting what appears to be the ideal target of 150 GWP for refrigerants.

This session will explore trend toward environmentally friendly refrigeration as natural refrigerants will continue to proliferate along these well-established paths of least resistance. Still, there is much to consider for system operators who must weigh the opportunity costs for selecting a natural refrigerant option vs traditional and upcoming lower GWP candidates. The session will highlight basic design features, advantages and challenges of competing refrigeration architectures in attempt of presenting a balanced look..

NAPSYS™ - HR PVC DWV 25/50

TAKING PVC TO NEW HEIGHTS We’ve taken the superior performance and cost-saving benefits of PVC and created a truly innovative DWV system for high-rise and plenum applications. Not only does NAPSYS™-HR help make installation faster, safer, and easier for you, it also meets fire and smoke regulations for high-rise DWV systems.

Features COST-EFFECTIVE AND EFFICIENT Lighter weight can mean faster installations—helping save time, labour, and money.

SAFER TO HANDLE The low-VOC (550 grams/litre) solvent cement application helps eliminate the need for—and possible risks associated with—specialized tools, like torches.

LONGER LIFECYCLE Our PVC offers virtually corrosion-proof, impact-resistant performance.

INCREDIBLY VERSATILE Can be used for both above and below grade applications with pipe and fittings available in 1.5- to 10-inch diameters and pipe in 12-foot lengths.

NAVAC – EMPOWERING YOU TO WORK SMARTER NAVAC is the world’s largest supplier of HVAC vacuum pumps, and also offers a wide array of tools, gauges, charging machines, recovery units and other industry-specific items. The company’s solutions meet a need for simpler, lighter, faster solutions that expedite service without sacrificing accuracy.

NAVAC draws upon its commitment to technical innovation, strong customer service and robust R&D allocation to deliver solutions offering unsurpassed efficiency, accuracy and ease of use.

NRDD and NRP8Di

NP4DLM and NEF6Li

• NAVAC’s next-generation NRDD Recovery Unit features a twin-cylinder compressor and oversized condenser with two rows of microchannel coils for exceptionally efficient vapor recovery. Just 25 pounds, the unit features a brushless DC motor providing substantial power and better starting performance under low voltage conditions in a compact size. Another benefit is ease of use: its large, LCD display is backlit for clearly visible, highly intuitive operation, and its sleek appearance offers the show-worthy confidence of high-precision manufacturing.

• Part of NAVAC’s trailblazing BreakFree Series™ of cordless HVAC tools, the NP4DLM Cordless Vacuum Pump features a high-performance lithium battery capable of up to one hour of continuous running time. At 15.4 pounds, the unit is exceedingly efficient and easy to carry and store. Twin-cylinder operation provides high vacuum down to 15 micron. A check valve prevents backflow; other highlights include an isolation valve, a lifting hook and a gas ballast for better moisture handling.

• NAVAC’s Master Series is anchored by the company’s NRP8Di and NRP6Di – the market’s first smart vacuum pumps. Featuring digital control interfaces, the units offer unsurpassed intuitiveness with features such as task reminder, extended evacuation for improved vacuum, and precision vacuum measurement technology with a built-in micron gauge and digital display. NAVAC NRP8Di and NRP6Di are the very first vacuum pumps driven by a DC motor. They are around 20% lighter than similar capacity products in the market.

• Another BreakFree Series™ member is the NEF6Li Cordless Power Flare, which yields accurate, hassle-free flares in a fraction of the time as traditional flaring. Equipped with a large-capacity rechargeable lithium battery, the unit makes flaring faster and simpler without sacrificing accuracy or consistency.

BIBBY-STE-CROIX EARNS INTERNATIONAL LIVING FUTURE INSTITUTE’S DECLARE LABEL FOR CAST IRON SOIL PIPE AND FITTINGS Bibby-Ste-Croix realizes that consumers and product specifiers are increasingly looking to use safe building products, whether it is to verify point of origin, to understand environmental impacts, or because they want to eliminate exposure to toxic ingredients. That’s why the International Living Future Institute (ILFI) created Declare, a ‘nutrition-label’ for products that provides a clear, elegant, and informative method to disclose a product’s ingredients. Declare provides product manufacturers the option for an additional level of confidence – 3rd-party validation from trusted 3rdparty verifiers.

“Transparency is an important ingredient to all of Bibby's products,” said Tom Leonard, president of Bibby-Ste-Croix. “The IFLI’s Declare program offers an important opportunity for us to share our company’s industry leadership in products that contribute to healthy and environmentally-safe design. Declare is designed to transform the way buildings are designed and built making them safer for occupants and first responders. It’s through this kind of transparency that change for the better will occur,” said Leonard.

The manufacturing atmosphere is changing and there are many progressive forward thinking companies that feel strongly about embracing thoughtful sustainability manufacturing practices.

Bibby is a manufacturer of cast iron soil pipe and fittings for storm and sanitary plumbing systems.

Their products are non-combustible, strong and durable. It’s important that specifiers understand the importance of specifying building products that do not off-gas toxins or generate dangerous gases when burned like plastic PVC piping that may cause harm to occupants and first responders. Bibby is pleased to be part of the certification program, advocacy tool and philosophy that defines the most advanced measure of sustainability in the built environment.

www.Bibby-Ste-Croix.com

CMPX #1143

When Life Safety When entering a commercial building, there’s a reasonable assumption that it’s safe for occupants and first responders.

KEEPING SCORE Toronto’s Bespoke Metrics is standardizing data and helping general contractors better evaluate subtrades. BY DAVID KENNEDY

L

ike competitors in most industries, general contractors aren’t particularly good at sharing. Whether it’s facing off over a major contract, or striving to be the first to adopt a new technology, rivalries can be fierce.

It’s no surprise that when Michael Ho, the CEO of Bespoke Metrics, set out to standardize how the Canadian construction industry manages risk and carries out counterparty assessments in 2016, it was an uphill battle.

“The GCs for the most part are very fierce competitors, as is the broker, as are the insurance entities, as are the subcontractors,” Ho said. “The sharing of data, despite everyone using similar systems and collecting the same data, has not been strong in this industry.”

Working to change this insular approach, Bespoke Metrics has signed up a significant list of major general contractors over the past three years, including Buttcon Ltd., Eastern Construction, EllisDon Corp., Graham Group Ltd., Pomerleau Inc. and Stuart Olson Inc., among others.

The Toronto-based tech firm has put together a suite of software solutions — known collectively as Compass — that streamline the pre-construction process by centralizing industry data. One key aspect of its platform, which is sold under a subscription-based model, is a prequalification tool GCs can use to vet subcontractors to ensure they’re capable of taking on various aspects of major projects.

Instead of leaving each GC to their own devices when it comes to collecting data from subs, the tool stores all the information GCs need in a central hub and uses a series of models to help manage counterparty risk.

“Not sharing information is just silly,” Ho said, adding that centralizing this type of data provides subcontractors muchneeded technical support and helps protect their privacy.

“Compass is simply catching construction up with what other industries have been doing for years.”.

A ‘ROTTEN TOMATOES’ SCORE FOR RISK Carrying out financial risk assessments for subtrades is nothing new for contractors. To utilize subcontractor default insur160

HPAC | MARCH 2020

ance (SDI), for instance, GCs need to prequalify the companies they’re working with. Up until now, most have been using internally-built systems or processes that don’t draw on wider industry data.

“It was pretty ad hoc,” Dan Radu, supply chain manager with Graham, said of the company’s previous method for evaluating subcontractors. “It was really manual… It involved us doing a lot of the grunt work and actually going out and gathering financials from the vendors. And not only do you have to gather them, you have to go through them, analyze them and score them. Then you would look at the scores and make your recommendations.”

Graham has been using Bespoke Metrics’ software tools to assess the subtrades since February 2019.

“They’re going out and extracting all the information from the vendors,” Radu said. “They’re ensuring them that they’re submitted the right way. They apply their Q Scores on it, and it’s great because our risk people can just do proactive risk-type stuff. They can just look at what’s provided and make a decision as opposed to doing all the grunt work to get to that point.”

To calculate the ‘Q Score’ — a measure of a subcontractor’s ability to meet its obligations on time and on budget — Bespoke Metrics uses a range of data points, including qualitative variables, financial information and health and safety records, among other inputs. It collects the information directly from subcontractors through a standard checklist it calls a Compass 1 Form.

“The sub enters in their data and we verify their data,” Ho says. “It’s not an audit function, but we do look for accuracy.

HPACMAG.COM

A screenshot of the Compass dashboard showing some of the software’s metrics.

ISTOCK/GETTY IMAGES PLUS

It’s very important because the next stage is dependent on the accuracy, completeness and the validity of that data.”

With the data in-hand, the company uses a number of custom-built models to create a relative risk curve for each sub that weighs their ability to perform a certain job on time and on budget. “It’s kind of like lining up the kids in class by height,” Ho adds. “There’s a tallest kid in class and there’s a shortest kid.”

Though Graham is still in the process of phasing in the new tool, Radu expects it will allow the company’s risk team to look at a far greater number of projects. “What it’s going to enable us to do is to do more financial assessments on vendors, whereas in the old way we just wouldn’t have had the capacity to do it,” he said.

In turn, Radu anticipates lower exposure to risk. “You can get hurt just as bad on the financial risk side as you can on the health and safety side, as far as projects being shut down because one of your trades went bankrupt or something like that.”

Along with simplifying the pre-qual process for generals, Bespoke says the 1 Form makes life easier for the subs, which can submit their data to one central hub as opposed to answering requests from all the GCs they’re currently working with. Subcontractors are also in control of their data, meaning their information is only shared if they give the go-ahead.

Moving forward, Ho said Compass will be focussed on increasing functionality and benefits for the entire subcontractor community.

NOT ‘SECRET SAUCE’ Right out of the gates, one of Ho’s major obstacles was overHPACMAG.COM

coming the tendency of general contractors to shy away from technology their competitors are using..

EllisDon was the first major general contractor to sign on.

According to Rosemarie Lipman, the chief innovation officer and senior vice-president of Digital and Data Engineering at EllisDon, the contractor had been taking a close look at their risk management strategy, including the information they collected from their subcontractors, when they were first approached by Ho. EllisDon decided using a standardized tool would benefit both the company and the overall construction industry.

“It was really this idea that there is no secret sauce,” Lipman said. “We are all collecting the same information. It is all driven by the [insurance] carriers and why don’t we make it easier for subcontractors to provide us with that information? And so, from EllisDon’s perspective, we wanted to facilitate that collection of information but also make it an industry tool and standardize it.”

Along with embracing Bespoke Metrics’ Compass tool, EllisDon invested in the company in 2017. The terms of the deal meant EllisDon gained no operational control, leaving the company to serve the industry from an unbiased position.

BRANCHING OUT Having taken a significant bite out of the Canadian construction industry — the company has about two dozen major GCs on board, as well as some 4,500 Canadian subcontractors in its system — Bespoke is beginning to think a bit bigger.

It signed up its first U.S. client in September 2018 and has continued expanding its reach south of the border since.

Compared to its growth in Canada, Ho said the company is expanding about twice as quickly in the U.S. “The speed and the turnover and adoption has simply just been faster because it’s a product that’s go-to-market,” he said. <> David Kennedy is the Editor of On-Site magazine, www.onsitemag.com.

TESTO

PRESENTED BY

TESTO 420 AIR FLOW CAPTURE HOOD

Intuitive IAQ Measurement The Bluetooth enabled testo 420 air flow capture hood features ergonomic handles, tiltable display, and light weight of less than 6.4 lbs. Frequent volume flow calculations in large rooms and measurements above head height can be carried out reliably and comfortably, and a large measuring button on the capture hood ensures easy recording of the measurements. The integrated volume flow straightener calms turbulence at swirl outlets and converts it into a virtually uniform air flow, allowing for highly accurate calculations of volume flow.

The control unit of the testo 420 enables you to measure flow velocity, volume flow, absolute pressure, temperature, and relative humidity. The automatic zeroing ensures higher accuracy for low pressures. This integrated measuring control unit was not just developed for volume flow measurement at ceiling outlets, as it can be removed from the capture hood and be used for pressure, flow, and volume flow measurements in ducts.

The testo 420 app enables live measurement streaming of HVAC systems using a smartphone or tablet. The app features a start and stop function and enables you to save your measurement data in .txt format, and creates the measurement protocol directly on site. Measurement results, such as the overall volume flow and the air exchange rate, can be directly assigned to customer-specific folder templates.
