2023 Bingo Card Anyone who grew up with a sibling has probably been told by either one or both parents “not to speak to your brother or sister that way.” Or that, it’s not polite to tell them “I told you so.” Even in the moments that you really want to. Well, I highly suspect there are some people in the industry who are currently struggling to hold on to that childhood lesson right about now with how slow it has taken for heat pumps to be adopted. I bet they wish they could yell it as loud as they can from the top of every mountain. On the flip side, those early adopters of heat pumps might be taking a bit more of a graceful approach and are simply happy that more and more people are coming to terms with the direction of the industry. My best guess is that it’s split somewhere along the lines of 50/50 between those who want to scream “I told you so,” and those who are simply happy to see the industry evolving. I will say, that for an industry that has been known to resist change and prefer to do things the way their mentors taught them, there are so many that are learning to embrace the change. For those people, I applaud. Looking back at this calendar year, I would summarize that 2023 was a year of so much

change. It has been the fi st year in a while where we weren’t put into lockdowns at some point and were able to feel some semblance of normal. I look back at these past 12 months and I think about how we are still just on the cusp of what is to come. If I were to create some type of crossword with the buzz words of the year, I’d say you’d see terms like heat pump, electrification, hybrid, carbon, and net zero, right up at the top of the list. The education around these topics will become so much more paramount to the success of contracting companies. I have heard radio commercials about heat pumps or rebate programs over the speakers while shopping at the grocery store. We are entering a time where homeowners will be the ones asking about heat pumps and it’ll be up to the tradespeople to be up to date on the nuances of the technology. For now, enjoy the chilly fall weather before we are blasted with a typical Canadian winter. Happy Holidays and hope our readers have a wonderful New Year. Cheers to 2024.

Federal pollution price on heating oil pauses
The federal government has announced relief for homeowners using propane as its space heating energy source.
By Leah Den Hartogh The Canadian government has paused the federal pollution price on heating oil for three years in an attempt to allow for homeowners to make the switch to heat pumps. Prime Minister Justin Trudeau made the announcement in a press conference on Oct. 26. “We have to make sure we’re fighting climate change in ways that supports all Canadians. That has been at the center of our choices as a government for the past eight years — fight climate change, while supporting Canadians in how we do it,” shares Trudeau. “That is why, we are announcing a three-year pause on the federal pollution price on heating oil, so that we can give everyone the time and ability to switch to heat pumps.”
Mixed reactions The home heating oil exemption will apply across Canada, however the policy is expected to help Atlantic Canada in particular; this is due to the fact that 30 per cent of homeowners in the region still use oil to heat their homes. Overall in Canada, heating oil accounts for 2.7 per cent of the total energy consumption by Canadian households in 2019, according to the Household and the Environment Survey: Energy Use, 2019 conducted by Statistics Canada. The Heating, Refrigeration, and Air Conditioning Institute of Canada (HRAI) applauded the federal government’s move to address support for low-income Canadians and those struggling to transition to low carbon heating, reports Martin Luymes, vice president or government stakeholder relations at HRAI. “We encourage additional measures of this type that facilitate the energy transition for Canadians in all regions of the country who are interested in making the transition, but lack the means to do so,” www.plumbingandhvac.ca

reports Luymes. Fellow industry associations are equally ecstatic over the announcement, “The Canadian Institute of Plumbing and Heating (CIPH) welcomes the federal government’s plan to help Canadians manage their home heating costs during these inflationary times,” explains Satinder Chera, CEO of CIPH. “We encourage the government to continue to balance the focus on energy transition with practical, economic solutions for all consumers.” The Canadian Propane Association (CPA) is calling on the government to fix the “oversight” by not including propane in the energy assistance program. “Propane, like heating oil, is a rural fuel,” said Shannon Watt, CPA’s president and CEO. “Those same rural communities that rely on heating oil also use propane. These are rural Canadians facing the same financial pressures as their neighbours and deserve the same breaks on their heating bills.” According to the CPA, there are upwards of 200,000 households that use propane to heat their homes and about 30,000 households in Atlantic Continued page "8"

GF acquires Uponor Uponor has offically been acquired by Georg Fischer (GF). The announcement was made on Nov. 13 by both companies, with the transaction closing occurring on the same date. Uponor will now become a new division within GF and will focus on building technology, whereas the infrastructure and utility businesses will move to GF Piping Systems. GF Uponor will be one of four divisions within the group, joining GF Piping Systems, GF Casting Solutions, and GF Machining Solutions. “We will continue to implement our Continued from page "7"
Canada alone. “Federal assistance must be fair to all rural Canadians, not a patchwork and the Prime Minister must also be there for those that depend on propane for heating,” said Watt, “Otherwise, efforts to help rural Canadians pay their energy bills will just end up creating winners and losers right in rural communities themselves, and nobody wants that.”
Axing the carbon tax The Canadian Federation of Independent Business (CFIB) isn’t as pleased with how the announcement to pause heating oil from the carbon tax and is looking for a complete overhaul of the federal carbon tax. “The recent announcement by the federal government that it will exempt only one type of heating fuel — heating oil — from the carbon tax is just the latest example of how unfair the tax has been to small businesses,” shared CFIB in a press release. “Now the government is choosing to help some Canadians with their heating costs by exempting them from the carbon tax, while leaving the majority out. CFIB is concerned that the recently announced enhancement to the rural top-up to Climate Action Incentive payments will be funded by reducing the small sliver of carbon tax revenue that is current earmarked to be returned to small business. The entire federal carbon tax structure is

strategy, and leverage powerful global trends, such as the need for safe and clean water, or more efficient energy use,” said Andreas Müller, GF’s CEO. “On behalf of all my colleagues, I am happy to welcome Uponor employees and start this new chapter together.” O r g an i z at i on a l c h an g e s w i l l b e implemented during 2024. Up onor Corporation’s president and CEO, Michael Rauterkus, will become a member of GF’s executive committee as president of the GF Uponor division. “I am proud to continue to steer GF beginning to look like a shell game,” explains Dan Kelly, CFIB’s president. As such, CFIB is calling on the federal government to overhaul the carbon tax system entirely by expanding the carbon tax exemption to all forms of heating fuels, including natural gas. In addition, they are calling to halt any future carbon tax increases, including the increase planned on April 1, 2024. “Small businesses have been waiting for a meaningful effort from government to return the carbon tax revenues it promised them since the tax was introduced. They have seen consumers and big businesses benefit from rebates and grants, while they were left in the cold,” Kelly concluded. “If the government can’t fix the carbon backstop system now, it’s time to scrap it and look for other ways to address climate change.” In Canada, heating homes and businesses isn’t a choice and tackling heating costs is an important way to address the higher cost of living, explains CFIB. “Last winter rural Canadians had difficulty paying residential energy bills.” In addition to the pause on federal pollution tax on heating oil, Trudeau announced a new pilot program that will be released in Atlantic Canada. “We’re working with provinces to install a free heat pump for people who are making at or below median household and encourage people to sign up for the change.”

Total value of building permits decreases in Sept.
The total monthly value of building permits in Canada decreased 6.5 per cent in September to $11.2 billion, reports Statistics Canada. Despite the monthly decrease, the total value of building permits in the third quarter of 2023 rose 4.9 per cent from the second quarter to $34.6 billion. In the residential sector, the total monthly value of residential permits increased 4.2 per cent to $7.2 billion. Th s was due largely to a 37.2 per cent increase in construction intentions in British Columbia. Declines seen in five provinces were offset by monthly gains in the value of residential permits in Newfoundland and Labrador (up by 20.8 per cent), Prince Edward Island (up by 16.2 per cent), Nova Scotia (up by 10.3 per cent), and Quebec (up by 9.1 per cent). In the third quarter of 2023, the residential sector increased 3.4 per cent to $21.2 billion. Additionally, 64,400 new units were authorized through building permits in the third quarter of 2023. On the non-residential side, the total monthly value of non-residential permits fell 21 per cent from August to $4 billion in September. Th s drop was attributed to the decline in construction intentions for the institutional component (down 50.7 per cent to $1.0 billion). Despite the sharp month-over-month decline, the total value of non-residential building permits in September 2023 ($4 billion) was 18.7 per cent higher than in September 2022 ($3.4 billion).

Traditional furnaces can benefit from zoning, however the system can be more flex ble when zoning with a heat pump. By Francesco Lo Presti
Homes are becoming more sophisticated and connected; a home’s heating system is no different. “By zoning an HVAC system, homeowners can access customized temperature control and energy efficiency,” said Mike Bauman, senior technical support specialist at Resideo. The concept of zoning isn’t new; it has been around for a while within the industry, but it isn’t talked about enough in residential applications. “We do see zoning in our industry as most modern and efficient hydronic floor radiant system’s zone. It’s there. But the interesting thing is when we flip the conversation and ask contractors installing a furnace or air conditioner how many are zoned, the conversation is a little different,” explains Dick Foster, president of ZoneFirst.

HVAC zoning refers to dividing a home or building into specific areas, each with its own thermostat control to regulate temperature independently. “When talking to a customer about the possibility of zoning, explain it the same way you would Plumbing & HVAC – November/Decemberexplain 2023 a light switch.

In a home, a customer wouldn’t want one light switch that controls the whole home. You fli k the switch, and the whole home is lit. That isn’t functional or the best. You want control in each room. Zoning is no different,” explains Foster. In terms of benefits to zoning, comfort is at the top of the list, “With a properly designed zoning system, the heat pump can cycle off completely when a particular zone is not calling for heating or cooling,” adds Foster. When broken down into single-stage, two-stage, or modulating equipment, it is almost always advantageous to zone using multi-stage technology. This is one of the main advantages of zoning a heat pump as it is typically two stages, explains John Brown, chief engineer at EWC Zone Controls. “An inverter heat pump can be more costeffici t than running a fossil fuel furnace, depending on the kilowatt rate versus the gas, liquid propane, and oil rate cost in a given area of the country.” It is important to remember that each individual system requires its own solution. A single-zone system would be more effective www.plumbingandhvac.ca

given time,” explains Foster. It is worth noting that the energy efficiency benefits of zoning a heat pump or furnace system can vary depending on the specific equipment, system design, and usage pattern of a home.

for a smaller space, whereas for larger homes, it might be better suited for a multi-zone approach. It should still be noted that a single-stage heat pump can still be zoned. “However, multi-stage and, in particular, modulating heat pumps lend themselves quite well to zoning,” explains Brown. “You can satisfy a single zone’s demand using the low BTU capacity of a modulating system or the fi st stage of a multi-stage heat pump. With a single-stage system, full BTU capacity is brought online for a single zone demand, which consumes more energy.”
Why a heat pump?
The answer to the question of which technology is better suited for zoning, heat www.plumbingandhvac.ca

pumps or furnances, might be surprising to some. “Traditional furnaces benefit from zoning, but they are not as flexible when compared to a heat pump,” explains Foster. A zoned air-to-air heat pump can be considered more energy efficient compared to a zoned furnace system because of the variable capacity operation. “Modern air-to-air heat pump systems often have a variable capacity operation, allowing the heat pump to adjust its output to match each zone’s heating or cooling demands more efficiently,” explains Foster. Additionally, since a heat pump’s heat transfer process occurs primarily through refrigeration circulation, “Zoning allows the heat pump to operate at a reduced capacity since only selected zones are conditioned at a
One of the most significant factors in an adequately zoned system is the quality of the ducts. “For a ducted zoning system, ideally, whoever is doing that layout would like a main trunk for each zone so that they can put a single damper in that zone,” explains Bauman. Brown adds, “Duct quality, more specifi ally duct sizing, is the biggest factor that affects the performance of any HVAC system, whether it’s zoned or not. Undersized ductwork results in high static pressure, noise complaints, poor airflow complaints and may affect the refrigeration circuit.” Older technology, like permanent split capacitor (PSC) indoor blower motors, can’t compensate for under-sized ductwork like a variable speed blower motor can. “Thus, the PSC motor drops and loses CFM as the static pressure of the HVAC system increases above 0.5 inches of water column,” explains Brown. When speaking specifically on duct sizing for heat pumps versus furnaces, there really is no difference between the sizing, explains Brown.
Dampers and airflow Dampers are a crucial element to a zoned system, but they “don’t need to be in a specific angle or position,” explains Foster. “While there isn’t a specific angle or position that is needed, there are different control strategies that are debated. One topic of debate is when a zone is active, should the damper be 100 per cent open? Or should it

But gradually closing the damper down as the zone comes
This can make the installation of a thermostat in a retrofit application tricky due to the requirement to run wires in areas where there were none before. “Then people may also upgrade equipment and move from a single stage to a multi-stage, and the concern will be whether they have enough wires to control that extra stage,” explains Bauman. Retrofit jobs will require much more creativity and planning when incorporating a zoned system. As Foster explains, “In these

Installations
The installations between a furnace and heat pump are quite similar but “The differences come down to wiring and programming. A heat pump installation has more wires to run and connect,” explains Brown. www.plumbingandhvac.ca

older homes, access to dampers may be an issue, and that’s something that may need to be changed. In these cases, mini-splits may be a solution. The mini-split system requires a contractor to bang a hole through a wall and have an inside and outside unit.” As previously mentioned above, there is no one right solution for zoning. There are different ways to zone a home, and each home will require its own approach. One solution can be utilizing mini-splits. “You are still

zoning the house when you decide to use a mini-split heat pump on a new addition because you cannot route the required duct size from your existing equipment to the new area. You will have two HVAC systems instead of one, but you have still zoned the new house addition,” explains Brown. While the reasoning isn’t completely clear as to why every home isn’t zoned, for some contractors, it’s because they are still unfamiliar with the technology. “I’ve talked to some contractors, and when I ask them about zoning, they mention things like its too difficult or they aren’t comfortable doing it. The thing is, no one is forcing contractors to zone. However, we need to zone more homes. We need to make homes run more effectively and efficiently, and zoning can help with that,” said Foster. :

After 10 years of mechanical issues, a Calgary-based home gets much needed upgrades to its mechanical systems. By Leah Den Hartogh

Sometimes in life, it can feel like nothing goes the way you hope it would. For one homeowner based in Calgary, Alta, it was more like 10 years of bad luck. Back in 2013, during a particularly devastating flood, most of the 8,000 sq. ft. house was heavily damaged, including the mechanical room. It might come as no shock to learn that due to the fact that much of the mechanical room was underwater following the flood, there were some major repairs needed to ensure the homeowner’s heating and cooling system was back up and operational again. The previous contractor after the flood decided to install three combi boilers to do the job. “He would run into all these issues where his house would overheat certain areas, and wouldn’t get heat unless other areas were getting heat,” explains, Alex Reid, project designer at Arpi’s Industries Ltd. “Hot water was really hit and miss.” The venting for the old equipment used to come out into the homeowner’s back garden.
Plumbing & HVAC – November/December 2023

This would result in six to eight inches of ice that would cover the whole back of his house. In addition, the foundation of the home is sandstone, which was starting to get damaged. “It was starting to physically harm his home and his property because of that. It was quite the rat's nest when we went in there,’ explains Reid.
What’s in the mechanical room? To fix the reoccurring issues, Arpi’s Industries Ltd fi st spoke to the homeowner for a couple of hours just to try and understand each of his concerns. “We wouldn’t have been able to if he wasn’t so in tune with his house and what’s been done over the 30 years that he’s owned it. So, part of that was just an absolute maze of pipe work in the mechanical room and we needed to fi st identify which supply and return lines went to what area first,” said Reid. “When we went in there, we spent a lot of time first identifying everything, labelling all the pipe work, then back that up with testing and making sure that each thermostat would then obviously work with each component that we designed.” www.plumbingandhvac.ca

out to different areas of the system at the same time with boilers only putting out one temperature? ” said Reid. In this case, they used Tekmar floating actuators with three way mixing valves. “The theory being when the high temperatures running the medium and the low temperatures will auto adjust to get what they require at that time with the three individual demands all coming back to the boiler. So, if one of the lower temperature zones is the only thing calling, the boilers will still modulate down and put out that lower temperature.”
everything down, I was able to determine there was essentially three different temperatures that we need the system to supply at any one time.” There was a high temperature that was run at about 160 F that runs to his fan coil in the mechanical room. A medium temperature was run to his steel radiators, which are located throughout his house and are over 100-years old. Lastly, the low temperature radiant was run at about 110 F, which is found in the basement. In addition, the steel radiators caused some concern of magnetite in the system, as such, a magnetic separator was installed. Radiant heating was installed on the main fl or and in the ensuite. To accomplish the many zones, Taco’s 003 ECM circulators were used and run in its smart auto adapt mode. In addition, Caleffi zone valves were used for each zone. “Part of the issue is how do you supply three different temperatures

After a decade of his mechanical room not working properly, who can blame him. As someone that likes to host large parties at all times of the year, the homeowner really just wanted to make sure the system was confide tly operational, no matter the number of people visiting his home. “This wasn’t a system that we designed around effici cies per se. It was more about making sure he was comfortable. Th s is kind of more about performance than chasing effici cies, explains Reid. “I’ll be in touch with him quire regularly over the winter just to see how it’s performing. The home was completed in July 2023, with this winter being the new mechanical rooms fi st. Reid expects the homeowner will still see some savings simply because of how poorly the
older system was designed. Like any project, there was a few unanticipated hiccups. “One of the bigger issues we had kind of run into is the way his house is structured. His office sits above his garage. The garage has a floating tin ceiling in it and so when we started hooking up some of the pipe work in the mechanical room, we realized that certain components weren’t responding the way they should be,” explains Reid. “When we started poking out head around the ceiling space, there was steel pipe work that was disconnected and some of it was capped off. There were a dozen junction boxes up there with wire everywhere. There was valves and pumps that nobody truly knew were there until we started poking around. It ended up being relatively simple.” The overall project ended up being quite the treat to be able to work on and design, shares Reid. “If you’re able to see this house, it’s truly amazing. It’s a piece of history.” :

The industry is entering a new era of water-based heating and cooling and there are plenty of new technologies being released like no other in Canada. By Michael Ridler Radiant heating has undergone a remarkable evolution. It has been a very long time since the days of the hypocaust (ancient Rome’s method of heating). Today, we are witnessing a signifi ant transformation in radiant heating products, from air-to-water heat pumps to intelligent controls that are propelling our industry forward. These new innovative methods within the industry, particularly in hydronic heating and cooling, are poised to become increasingly prevalent in Canadian homes. Before taking a deep diving into hydronic panel technologies, it’s crucial to address the subject of controls. The control systems represent a pivotal, yet often overlooked,

way we heat and cool our homes. The right control system is the linchpin of efficiency; conversely, ill-suited controls can reduce a system to mere operation without delivering effective performance. When it comes to selecting controls for hydronic systems, the initial cost often overshadows the importance of choosing the most effective control for the job. As the industry begins to shift from traditional boilers to hydronic heat pumps, there’s a pressing need to prioritize education on controls over mere cost considerations. The reality is that inexpensive controls may suffic for a boiler, but when it comes to a hydronic heat pump, it can lead to increased costs,

diminished trust in the system’s efficiency, and the expertise of the installer or designer.
Making the investment
For instance, a $100 control might operate a heat pump adequately, but investing in a $500 control could optimize the system’s thermal efficiency and achieve the highest possible coeffi ent of performance (COP). That additional $400 is not an expense but an investment in long-term savings and system reliability. Today’s controls are also created to be able to apply to a hybrid approach to home heating, with or without a boiler. There are versatile

As we transition away from boilers, it’s vital to remember that heat pumps require different piping and control strategies to prevent issues such as high electricity bills, discomfort, and equipment failure. Heat pumps are sensitive to high return water temperatures, while boilers stop condensing, heat pumps risk compressor damage.
Simplifying complex challenges
Integrated controls within an indoor module can help simplify the complex challenge of managing a system capable of heating, cooling, providing domestic hot water, and

These controls are ideal for contractors experienced with hydronic heat pumps, providing a solution that brings their applications to life. Recent enhancements to control technology has seen some new features, including having access to external weather data, which enables contractors to ensure peak operational efficiency beyond what a

manage multiple hydronic heat pumps and backup boilers, whether electric or gas. It’s important to acknowledge that innovation doesn’t always mean starting from scratch. Sometimes the most effective solutions are already within our grasp, waiting to be recognized and utilized in new ways. This is exemplified by my personal experience with integrating modern technology into my own home’s heating and cooling system. I sought a straightforward method to control an air-to-water heat pump paired with an air handler for cooling and radiant floor heating. A critical requirement was to prevent chilled water from circulating through the radiant floor slabs. The solution emerged from a creative application of priority calls and leveraging an air handler control for forced air heat pumps, which was developed over a decade ago; long before hydronic heat pumps became a focal point in the industry. This control, which originally was not designed with today’s hydronic heat pumps in mind, proved to be remarkably adaptable. By using it to orchestrate the operation of the system, ensuring that cooling and heating demands were met without the risk of inappropriate chilled water circulation, it demonstrated that sometimes the tools we need are already at our disposal. This approach not only solved the challenge efficiently but also underscored the value of looking at existing technologies through a new lens, especially as we navigate the evolving landscape of hydronic heating and cooling.
Sophisticated controls As we venture beyond the realm of controls, we encounter equally compelling innovations in hydronic heating technology. While hydronic cooling is a staple in commercial projects, its application in residential settings
This Jaga Clima Canal was recently installed on a five-ton heat pump in Ontario. is less common. However, the importance of sophisticated control strategies becomes even more critical when introducing chilled water systems into homes. Reflecting on my previous discussion about controls, it’s clear that inadequate controls can lead to dire consequences, such as inadvertently circulating chilled water where it’s not intended. This year has seen the emergence of some particularly interesting and straightforward products. In my own residence, I’ve installed an air-to-water heat pump, yet I haven’t incorporated hydronic heating — yet. The ductwork in my home could only be described as a disaster, leading to a staggering 15 F temperature variance across fl ors. To address this, I wasn’t going to rip my home apart to put in new ductwork. Instead, I ran a 3/4-inch piece of PEX into my attic and used some high-quality connectors. I’m considering three innovative products. One of my top choices is trench convectors. Although there’s a higher initial cost for
the equipment, the operation savings are significant due to its ability to produce usable heat at temperatures as low as 95 F. This efficiency translates into an impressive COP for the heat pump, reducing monthly heating and cooling costs over the equipment’s lifespan. However, we must acknowledge the premium that accompanies this advanced technology. Another product that caught my attention was wall-mounted units, which resemble high-end panel radiators, but are highperformance convectors designed for both heating and cooling. They offer an aesthetically pleasing and cost-effective retrofit option for homes transitioning from boilers to air-to-water heat pumps. Its combination of performance and affordability makes it an undeniable solution. New to the panel market is technology that can address few point concerns without the need for a condensation tray or drain. Th s technology is very versatile and can be designed not only for ceiling panels but also as a drywall panel that can be mounted on a wall, simplifying the installation of hydronic heating and cooling systems. I’m curious about the cool technologies our readers have encountered in the field of hydronic heating and cooling. I would love to hear from you, see your photos, and learn from your experiences. Please share what’s caught your eye and what innovations you’re excited about. : Michael Ridler is the general manager at Eden Energy Equipment.

Glide is the phenomenon that all refrigerant components will boil at different temperatures. By Greg Scrivener
This evaporator uses a high-glide refrigerant.
26
Earlier this year we discussed how to understand and take subcooling and superheat measurements. We’ve also discussed evaporator and condenser performance, and going back a couple of years, we went through the differences between azeotropic and zeotropic refrigerant blends. In this issue, we will revisit glide to help gain a better appreciation for it and help to understand the nuances that high-glide refrigerants have. Recall that many refrigerants are a mixture of other refrigerants and that these blends can be either azeotropic, which means they do not separate into their parts while saturated, or zeotropic, which means the individual components evaporate and condense at different temperatures. R449A for example is a zeotropic blend of R32, R25, R1234yf, and R134a, at the following proportions: 24.3 per cent, 24.7 per cent, 25.3 per cent, and 25.7 per cent respectively. Glide is the phenomenon of refrigerant components boiling at different temperatures; we are going to use pressure-enthalpy (Ph) curves to demonstrate what happens to the component temperatures when we have a high-glide refrigerant like R449A. To get our bearing with Ph curves, Figure 1 shows a typical Ph curve for a refrigerant that
Plumbing & HVAC – November/December 2023
PHVAC-NovDec2023.indd 26
doesn’t have glide. The green line represents the refrigerant boiling in the evaporator at a constant pressure (and therefore a constant temperature), the red line is the refrigerant vapour being compressed in the compressor, the dark blue line is the refrigerant rejecting heat and condensing at a constant pressure (and therefore constant temperature) in the condenser, and the purple line represents the refrigerant being expanded from the condensing pressure to the evaporating pressure in an expansion device.
Figure 1: A typical Ph curve showing a line of constant temperature.
Lines of constant temperature
The refrigeration cycle remains the same when we use a refrigerant with a high glide, but the lines of constant temperature are no longer horizontal on the Ph diagram. In other words, unlike a pure fluid or azeotropic blend, there www.plumbingandhvac.ca

Condensing units are often selected based on the mean temperature to make the system less expensive. is no direct relationship between temperature and pressure when the fluid is saturated. Th s can be a bit hard to conceptualize because we are taught very early that refrigerants boil at a constant temperature. Figure 2 shows what this looks like for an evaporator using R449A. The figure shows three lines of constant temperature. The top one is 21 F and intersects the saturation curve when the refrigerant is 100 per cent vapour at 46 psig. The bottom line is 11 F and interests the saturation curve when the refrigerant is 100 per cent liquid at 46 psig. Th s difference is the glide of the refrigerant, and, in this specific case, it equals 10 F (21 F subtracting 11 F). A similar effect is also happening at the condenser.
remember these is to imagine moving into the saturation dome horizontally from each side by adding or removing energy (corresponding to enthalpy). From the left, you are moving from an area of subcooled liquid; by adding energy you move closer and closer to the saturation dome. When you hit the line, the liquid is 100 per cent saturated, which means that if you add any more energy the liquid will start to boil forming bubbles. Th s is why it is the bubble point. Conversely, moving from the right into the saturation dome requires removing energy from superheated vapour; when you hit the line, the vapour is 100 per cent saturated. When saturated vapour has any energy
removed, a drop of liquid starts to form, just like the dew drops from water in the air. This is why it is the dew point.
Superheat and subcooling You may recall that we did several superheat and subcooling calculations last June. Figure 3 shows the same example we used previously but the refrigerant is changed from R410A to R449A. As you can see, measuring a temperature of 55 F in this case leads to a superheat calculation of 15 F since the pressure measurement of 71.8 psig means the refrigerant in the evaporator is 40 F. Pay attention to the slider on the P-T app; it is set Continued on page “29”

Continued from page “27”
R449A as shown in the Ph diagram in Figure 5; again, there is almost a 10 F glide. When you look at selection charts for condensers, capacities are given at a temperature difference (TD) between ambient air and the condensing refrigerant, as shown in Figure 6. For condensers, this selection charge almost always uses the mean or average
to “dew,” which is correct. Figure 4 shows the results if “bubble” is selected incorrectly. Notice that you would calculate the superheat to be 24 F (55 F temperature measurement minus the 31 F assumed temperature in the coil based

temperature of the condensing refrigerant with glide and not the dew point. In the case of our example in Figure 5, this would mean that the manufacturer would assume a 109 F condensing temperature when calculating the TD. In other words, if our design ambient temperature was 95 F, then this condenser would have a 14 F average TD (109 F subtracting 95 F). It would be possible, and more energy efficient, to use the dew point temperature to select condensers. Th s is where a bit of a trick can be played when discussing how efficient high-glide drop-in refrigerants are compared
to their replacements. Energy comparisons often assume compressors operate at the same condensing temperature which means the dew point temperature when viewed from the perspective of the compressor, when in reality the condensers are being selected based on the mean temperature to make the system less expensive (and less efficient). Where condensers get the disadvantage with the ratings, the evaporators get the advantage. Th s is because with evaporators, the refrigerant is colder at the inlet than the outlet and therefore, when outlet suction temperature remains the same as a refrigerant with no glide, the coil is on average colder and can do more cooling. I continue to see technicians and installers get glide wrong when setting expansion valves and other system setpoints and it’s not a surprise. As you can see, high-glide refrigerants can cause headaches when troubleshooting and when doing system calculations. : Greg Scrivener is the lead refrigeration engineer and a partner at Laporte Consultants, Calgary, and works throughout Canada and the U.S. He is a professional engineer and journeyperson refrigeration mechanic.

Entering into the right partnership can help ensure that the company maintains that family business-feel and create a win-win situation for everyone involved. By Leah Den Hartogh

It isn’t easy stepping down from a business. When there has been so much hard work, blood, sweat, and tears put into a company, for so many years, the decision to walk away from a business that you helped cultivate or maybe even create can be very difficult. As our shop management expert, Ron C oleman, has touched on in previous ar ticles, succession planning isn’t an easy task. Do you sell your company to a family member, employee, or a third-party? For each individual, the answer will be different. There is another option. Contractors looking at transitional retirement have the option to sell a portion of the business but maintain some control. One of the benefits to this solution is that it allows for companies to maintain a small family business-feel but compete in the new world the industry is currently facing, reports Spencer Ross, co-founder of MechCan. “We believe, fundamentally, that these businesses are strongest when they maintain that small family, local business feel.”

How it works
At the core, the aim of this specific type of strategy is to create a win-win relationship between the acquiring company and the selling owner-operator company. “It helps to have some flex bility to sort of deliver the solution that the seller wants, and so the idea of this sort of 80/20 to 60/40 structure is to maintain the alignment,” explains Arty Phillips, co-founder of MechCan. An 80/20 to 60/40 structure means that the acquiring company would receive a portion of control of the company, whether www.plumbingandhvac.ca

it is somewhere in the 80 to 60 per cent range, and the previous owner would maintain a portion of ownership. One of the benefits that this type of partnership can offer the company is through negotiated purchasing deals with suppliers. By being a part of a larger group, contractors can access strategic partnerships with suppliers that can benefit their business. “During the pandemic, we saw equipment, materials, and commodity prices rising. The power
electrical trades. For some, it was a way to maintain the company name. “Basically, I put the business up for sale with a mergers and acquisitions company and because I was running my business still, I didn’t have the time and the expertise to sell a business on my own,” explains Bart Rietveld, president at B.R.’s Plumbing & Heating Inc. “That’s when MechCan came along. They had a vision and
and I didn’t want to sell to a company that would completely get rid of all my staff and completely change everything,” explains Barry. “I worked towards building a great name and I’m only 50 and I’m not ready to retire. I love HVAC, it becomes part of your blood.” Since the acquisition, the company has expanded into the plumbing market. “I don’t think we would have ever done that if it was

I didn’t want to sell to somebody that was going to change everything.” For Rietveld, the name was important because it was how all of his customers knew his work. Since the acquisition over a year ago, Rietveld has found such a weight lifted off his shoulders. “As far as day-to-day business, things haven’t really changed. It’s working. We just keep doing what we’re doing and driving the business like usual.” He is even able to now take his Fridays off from work. With this specific partnership, MechCan maintains an 80 per cent share in the company and Rietveld has 10 per cent, as he sold his other 10 per cent to one of his employees.
Building a legacy
For Mike Barry, owner partner at Comfort Zone Heating & Air Conditioning, it was about building a legacy. “I had an investment guy ask me one time, “are you building a legacy or trying to make money?” I guess I’m building a legacy,” shares Barry. When he sold his shares of the company to MechCan, he entered into a 70/30 partnership. His business was making around $8 million in revenue, but felt like the company could grow even more. “I’m pretty proud of my business
on my own.” As for advice to anyone thinking about entering into some type of partnership, “I just think for a person that owns their own business, they should look at where we are in this industry and what’s coming and have a real hard look at the future. That would be my advice,” shares Barry.
Employee retention
Following the fi alization of each acquisition there remains a high employee retention rate. “Having a high retention of employees is core to our thesis, there is always someone that doesn’t want change and move on, either before or after,” shares Phillips. “When I think about the type of people that are reading an article like this, this is often their only time going through a transaction of this nature and I think one thing that’s interesting is that these acquisitions are about ongoing conversations.” Oftentimes, there are many different conversations working through the kinks before the partnership is drafted. “It’s the only way that this really works for us as if we can make it work for our partners,” explains Phillips. “That is among the many things that really aligns us to figu e out how to create win-wins with everybody that we do deals with.” :
