JM-1000 Mini-Jet

™

You don’t always need a heavy duty jetter to clear a clogged drain.

General’s JM-1000 Mini-Jet™ brings surprising cleaning power to the job. You can be blasting away with this 23 lbs. powerhouse before you could get your big jetter off the truck.

Clear small lines, clogged sinks, and laundry drains – with 1500 psi of cleaning power. Whether on the job, or on the truck, its small footprint never seems to “get in the way.”

Pound for pound and dollar for dollar, the Mini-Jet is a great (and small) investment.

Now available with stainless steel/Teflon core hose.

See you in T.O.

Every two years we get the opportunity to meet up with you, our valued readers, at trade shows in Toronto in March and then out in Western Canada later in the year. (We’ll see our friends in Montreal next year.)

Our time spent chatting with manufacturers, distributors and those on the tools at our booth (N22 at CMPX), at exhibitors’ booths, or in the show aisles, allows us to learn more about the new products, services and techniques that are making an impact on jobsites, as well as about some of the projects you’ve been working on.

A Show in Print If you are not able to get out to the Metro Toronto Convention Centre for this year’s CMPX show, and even if you are, you’ll not want to miss our trade show in print, the biennial Product Showcase, which starts on page 155 of this issue. Featuring specifications and details for more than 200 products – all available from Canadian distributors – it’s a must read that’s only available in the pages of Mechanical Business.

Often enough, these conversations turn into feature articles, like the one about the innovative heating system that is helping to keep some northern First Nations homes warm and safe (see page 118).

A conversation about the business side of mechanicals is also how we ended up working with David Succurro to discuss some of the things to be mindful of when trying to keep a project in black ink, and you in profit (see page 88).

AHR Expo delivers in Florida

HRAI’s Martin Luymes discusses the association’s goals at a recent meeting of the Greater Toronto Area chapter.

Attracting more than 50,000 visitors and almost 2,000 exhibitors, the 2020 edition of the AHR Expo was buzzing with energy as the future of the HVAC/R industry was on full display at the Orange County Convention Center in Orlando, Fla., in early February. A common theme among products introduced at the show was integration of smart controls and connectivity, as well as advancements in efficiencies and product performance. Top performing products were recognized during the annual AHR Innovation Awards, with top prize going to Danfoss. “We congratulate all our winners — and Danfoss for developing a phenomenal Product of the Year with the CO2 Adaptive Liquid Management Solution — and challenge everyone in the industry to keep innovating, taking risks and working to better the industry,” said Mark Stevens, show manager. A full list of winners is available on the show’s website. The 2021 edition of the AHR Expo will be held January 25-27 at the McCormick Place Convention Center in Chicago. ahrexpo.com

HRAI doubling down on advocacy “We’ve been good at reacting to changes; we’ve not been very effective in setting the agenda. That’s something we are going to change,” stated Martin Luymes, HRAI’s vice-president of government and stakeholder relations, at a recent Greater Toronto Area chapter meeting held in Vaughan, Ont. Luymes discussed the goals for the association, which he described as a re-focusing on advocacy.

“It takes a village to develop a succession plan,” stated CIPH Ontario Region business luncheon speaker Gail Levitt as she explained about the importance of developing succession plans for key positions in all departments of a corporation.

Speaking to more than 100 attendees in Mississauga, Ont., she queried the audience about whether their company would have a plan in place if they were to go on vacation and not return to work. To successfully plan forward, Levitt advises that companies anticipate change, put their plans in writing, proactively develop talent, consider succession to be an ongoing process, and to start the process five or more years in advance of anticipated needs. ciph.com

Managing lead in drinking water

Putting their time where their hearts are, tekmar employees volunteered their time to help out the North Okanagan Valley Gleaners Society in late 2019. The Gleaners Society is a global charity that accepts local farm donations of edible but malformed vegetables, which volunteers then clean, chop, dehydrate and package for use in dry soup mix that is distributed globally to feed the hungry. Over a three-week period, 16 tekmar employees produced 8,500 meals to be shipped worldwide. In addition, the company named Gleaners as its charity of the year, donating $2,000 to the organization, enough to produce an additional 100,000 meals. tekmarcontrols.com

The McGill University Health Centre (MUHC) and the McGill Healthcare Infrastructure Group (MHIG) have obtained a second LEED Gold certification, a first in Quebec. The certification, LEED Gold for Existing Buildings, was awarded by the Canada Green Building Council to the new MUHC Glen site, which opened in 2015 in Montreal. In 2016, the site obtained a LEED Gold for New Construction certification.

The MUHC Glen site implemented energyefficient initiatives resulting in less energy consumption than the average Canadian hospital, resulting in $2.5 million in annual savings. Some of the features include: lowflow faucets that decrease potable water consumption; a decreased heat island effect largely due to the maintenance of green spaces and the use of highly reflective materials; charging stations for electric vehicles; and a waste management centre. cagbc.org

Reader Profile Marci rci M McMullen: cMullen: A community-minded comm outlook ok It’s not unusual for a mechanical contracting company to transition from one generation to the next, but it’s not very often that the second-generation owner gives up a career in cosmetics to purchase the family business. But that’s the path that Marci McMullen followed when joining, and subsequently buying, Haven Home ClimateCare from her father.

“My cosmetic career ended when I was 32 and joined Haven,” she explains. “It was an interesting transition from selling make up to selling furnaces.”

Q A Q A

Moving to Kingston, Ont., from Toronto to operate Haven Home ClimateCare with her husband, her company now has 46 employees, 25 trucks, and serves Kingston and the surrounding areas, servicing and installing a wide range of HVAC and fireplace products.

We recently caught up with her to talk a little about the business of HVAC, operating her company, and supporting her community.

What’s the biggest challenge running a mechanical contracting business nowadays?

The lack of people getting into the trades. It is leaving us with a very limited pool of workers to choose from.

What’s your guiding principle for managing your company?

To provide an atmosphere that allows our team to grow and enhance their abilities, so they can provide the best customer experience to our clients.

STAYING IN THE LOOP:

SIZING RADIANT PIPE I

nstalling a hydronic system that meets a client’s expectations is vital for a business that wants to secure – and possibly grow – its share of the radiant pie. To this end, selecting the correct size of pipe is critical to ensuring a happy and comfortable customer.

CALCULATE THE BUILDING LOAD When it comes to any heating system, hydronic or otherwise, one of the first things that a tech needs to know is the building load – how much energy needs to be put back into the building every hour to maintain a comfortable setpoint.

That’s usually question number one. For a residence, it can be anywhere from five to 30 BTUHs per square foot. This can go even higher if you have rooms that have lots of glazing and vaulted ceilings, and applications like commercial snowmelt can take that well beyond residential requirements.

28

M e c h a n i c a l

B u s i n e s s

0 4 . 2 0

Radiant systems are typically designed to handle the full load, however, there are instances where the hydronics may need to pair up with a secondary heat source.

Take, for example, a nine-square-metre breakfast nook that is all glass and vaulted ceilings. That’s a room with a really high heat loss, and there may not be enough surface area to handle the full load with the hydronic loop. Here, you would want to use that secondary heat source to top up the heat on the coldest days of the year.

HYDRONICS

LET THE APPLICATION BE YOUR GUIDE We typically see the use of 3/8” pipe, all the way up to 3/4”, for radiant heating. While there are a number of general rules that can help with selecting an appropriate pipe diameter to use in a particular hydronic heating system, the application itself will often be one of the main influences on tubing diameter and spacing.

For example, in a warehouse with large open areas, you’re typically going to use larger diameter pipe. In a residence, nine times out of 10, 1/2” pipe will suffice.

Get your spacing right

In residential applications, expect the centre-to-centre spacing to be tighter than those warehouse applications, since temperature variance across the floor is far more noticeable in sock feet rather than steel-toe boots.

Consistent comfort comes from consistent pipe spacing. The CAD drawing never looks exactly like the as-built building, so do your best to navigate around obstacles and keep spacing as consistent as possible. There are cases where you may have tighter pipe spacing, near a large window, for example, but it is important to maintain pipe spacing.

When it comes to a radiant cooling application, we g, normally go with 5/8” pipe at 6” spacing, in order to accommodate the higher flow rates associated with cooling applications.

Where loads vary, it is possible to accommodate to the loads by adjusting flow. hydr In a hydronic system, pipe spacing usually ranges from 6” to 18” on-centre. o In a large warehouse, where the thermostat setp setpoint may be lower than it would be in a living room, it m might be possible to get away with longer pipe lengths a wider pipe spacing. and Closer pipe spacing improves the uniformity of the floor surface temperature and lowers the heating water temperature, resulting in greater energy efficiency. It also increases the heat output of the radiant panel at a given heating water temperature and provides a faster r response time.

Loop lengths, flow rates and pipe diameters The diameter of pipe being used will often dictate the maximum length of the circuits or loops in a system. For example, circuit lengths will typically range nge pipe between 250 feet and 330 feet with 1/2”” pipe, whereas if you are using 5/8” or 3/4” pipe, lengths can be anywhere from 250 feet to 500 feet.

While you could gain more loop circuit distance with 1” pipe, it is rarely used for radiant because of its limited flexibility.

Many system designers prefer to avoid the theoretical maximum loop length limit since, generally speaking, the longer a circuit’s length, the higher its head loss will be. This may require more pumping capacity, meaning larger, more expensive circulators.

When selecting an appropriate size of pipe, keep the design of the building in mind. Hiding manifolds and servicing smaller zones will all factor into tubing size selection.

The use of larger diameter pipe can often result in fewer manifold locations and fewer circuits, which can also make for a quicker installation, however, smaller diameter pipe may be easier to install in more complex rooms and layouts.

30

M e c h a n i c a l

B u s i n e s s

In Increasing pipe spacing requires a higher water tem temperature to achieve the same output and could result in stripin (concentrated hot and cold spots). striping

MIXING IT UP There are times when a combination of pipe diameters could be used within one system.

For instance, a snow and ice melting system in a parking lot may use a larger diameter than the stairs leading into the building.

These snow and ice melting applications need higher flow rates than comfort heating, which makes larger diameter pipe beneficial. In areas such as a garage, which does not necessarily need to be kept at the same setpoint as the inside of the home, a larger pipe diameter and wider spacing can be a viable design choice.

In some cases, it may be helpful to run a larger diameter, pre-insulated pipe to a remote manifold, from which smaller diameter tubing can be run for each zone or loop.

In residential projects, it’s not that common to see a mixture of pipe sizes. When a variety of diameters are used, it’s typically due to the inclusion of a snow and ice melt system, or the use of a panel product that installs on top of a subfloor and only takes a set pipe size.

Where these panel systems are used, say in a master bathroom or kitchen, the pipes and the system flow will have to be sized to the panels, while the rest of the home may have pipe embedded in a slab, so size options are not as limited.

OUTDOOR SKATING PATH PUTS SPOTLIGHT ON

W

CO2

hen the team at Cimco was presented with the chance to work on the proposed Barbara Ann Scott outdoor skating path project at College Park in Toronto, it was the perfect opportunity for them to push the sustainability envelope.

Completed in 2019, the five-metre wide pathway was the world’s first outdoor skating path using a CO2 direct system. And while skaters may not even think about the environmental side of the project, energy use, greenhouse gas and global warming potential were at the core of the city’s decision to go with CO2, says David Fauser, Cimco’s director of sales.

The stars were perfectly aligned for the city to take the company’s proposal into consideration.

Toronto is among a number of municipalities that have set aggressive sustainability goals. Among other initiatives, it has made a public pledge to become one of the world’s greenest cities in the world.

In fact, in September of 2019, Mayor John Tory announced Toronto’s goal to reduce 80 per cent of greenhouse gas emissions by 2050.

DID YOU KNOW? Toronto is one of 500 federal, provincial and municipal governments that have officially declared climate emergencies in Canada over the past year.

Cimco’s Chloe Milano, David Fauser and John Shaw try out the ice.

do well at winter temperatures and produce a much better coefficient of performance. It was the ideal scenario to deliver huge savings.

That’s why they decided to move forward with our proposal.”

It took a leap of faith on the part of the city since upfront costs would be higher, but the opportunity to reduce greenhouse gas emissions was a top priority. The numbers were enough to convince them, Fauser says.

“We were able to propose a solution that aligned with their goal of being a sustainability champion,” says Fauser. “We believed that a CO2 direct system was the best option for them.”

“Local legislators interested in addressing the climate emergency always want to know what the environmental impact is,” he says.

“CO2’s global warming potential (GWP) is 1. They also liked that the projected energy savings of a CO2 system were significant, further aligning with Toronto’s commitment to sustainability.”

His company has a solid track record of using CO2 in skating rinks, but had never tried it in a skate path, but they could see the potential.

CO2 is ideal for many rink installations, especially in colder climates, Fauser explains. “CO2 is extremely efficient in mid-winter.”

“It answered all of their needs: it provides superior ice quality, higher energy savings, and low global warming potential,” he explains. “CO2 direct systems

He says that we are on the edge of a fundamental reshaping of arena refrigeration. “I’m excited about CO2. It has everything – it’s nontoxic, saves energy, provides better ice quality, and delivers a strong environmental value proposition.”

A winding, but consistent, path One of the main design challenges for the project was that, unlike a standard rink, the skate path has a lot of twists and turns. It took a team of highly experienced engineers to figure out how to make it all work, Fauser says.

“Typically, you would use polyethylene pipe,” he says. “In this floor, we used stainless steel tubing as it’s suitable for CO2 and is pliable, so we could perfectly shape the skating path.”

One advantage that this project has is that the refrigerant evaporates in the tubing, so no heat exchangers were required, Fauser notes.

“It’s all about performance and quality. Glycol or brine experience sensible heat transfer. They typically leave the refrigeration package at about 15°F and pick up at least two degrees in the circuit. Then they are recirculated to the heat exchanger and cooled back to 15°F.” To cool the glycol or brine, he says, the refrigerant needs to be several degrees colder than the transfer fluid.

“CO2, on the other hand, experiences latent heat transfer and is highly efficient at absorbing heat. When CO2 leaves at 17°F, it returns at the same temperature resulting in a better sheet of ice with negligible temperature difference across the surface. So, you have superior ice, and this is far more efficient.”

CO2 uses a higher suction temperature, lowering the discharge pressure and raising the suction pressure further enhances energy savings, he adds.

THE CASE FOR

HEAT RECOVERY

Complex, yet simple Once the materials were selected, installing the system was relatively simple, says Fauser.

“We put the system in, connected it to the floor and that’s about it.”

The components include over 12 kilometres of pipe, three semi-hermetic compressors, two five-horsepower circulating pumps, one receiver where the CO2 is stored, and an electrical panel and control system.

“This is a simple system and there are fewer components to maintain,” he explains, adding that the circulating pumps use only about a fifth of the energy typically used by brine or glycol pumps.

Dave Rogers, service mechanic with CIMCO, in the mechanical room with the compressors.

What many people may not realize is that most ice rinks use natural gas for heating. As such, they are prolific generators of greenhouse gas emissions.

“Seventeen per cent of all greenhouse gas emissions come from ice rinks. A lot comes from heating buildings using natural gas. That’s pretty crazy,” says Fauser. “Every unit of heat pulled from the ice surface releases four units of energy outside. Anyone putting in ice rinks can capture that and use it within the building – heat recovery is a big step towards achieving net zero.”

Heat recovery was not part of the scope for the Barbara Ann Scott project. But that doesn’t mean it won’t be in the future.

Fauser believes they can use the heat from the skate path to heat the parking garage, once the existing equipment in the garage requires replacement.

“We just completed a similar project in Vancouver where we are rejecting 100 per cent of waste heat into their district heating loop. It’s pretty amazing that we can heat homes while maintaining outdoor ice.”

The lower global warming potential of CO2 has led to renewed interest in its application.

Let the customer SPEAK

A logical approach to emotion Professional sales people recognize that people buy on emotion, and that the control of personal comfort is highly emotional.

Provide a solution that will make them feel good about the way you can help their family be comfortable and healthy.

People do need logical reasons to help justify emotional decisions, but that is why both the questioning and the testing are so important when addressing comfort opportunities.

It gives people a logical reason to make that emotional decision.

In the context of resolving comfort concerns, cerns, nuine start by asking questions that are of genuine interest to your customer.

Use questions that allow them to speakk openly and emotionally about their expectations off comfort, and leave the timing and financing questions for later.r.

In a sales process, the more they talk, the more they like you; and, if they like you, they are predisposed to trust you. As well, the more they talk, the more you learn about their needs and how they would measure success.

This isn’t a trick. Every professional sales training program offered will outline the human behaviours that make this true (and yes that is a hint to invest in regular, repeated sales training to reinforce the strategies and techniques to build trust – at least twice per year).

By asking my nephew a question like, “Tell me about your kids. How are they affected by this issue?” you might hear that the son really would prefer to sleep in the basement bedroom that has its own space heater, but they don’t want him down there in case the basement floods again.

Or, you might hear that the difference in temperature between his room and his sister’s room is cause for annoying jealous arguments.

The emotion behind their answers will give valuable clues as to how they would measure a successful outcome, their urgency, and even their budget to resolve the issue.

After 15 minutes of helpful, insightful questions, you can move from the kitchen table and start into the diagnostic testing to help find the most effective solution.

In my nephew’s home, comparing airflow and temperatures at the register discharge in each of the kid’s rooms, the static pressure and the discharge temperature in the duct system at the top of the furnace, even the output capacity of the space heater in the basement would all be of interest.

You might even consider or refer to more advanced testing, such as an infrared camera in the right weather to determine heat loss or gain anomalies in the son’s bedroom.

Just like at the doctor’s office where they start by benchmarking your current health status using a thorough, professional approach, the measurements and gentle questioning help build trust.

Train, train, train In my opinion, professional HVAC salespeople should invest three or four days per year in training. Some of this should be technical training, but training should also help identify questions that can be used to uncover the real problems clients are facing and the emotions behind them.

M e c h a n i c a l

Imagine heading back to the kitchen table and being able to say, “From what you told me and from what we measured, the best solution to make sure your son and daughter’s bedroom stay within 1°C of each other is to…”

There are three elements to this statement that are specifically important when resolving comfort issues. First, allowing the customer to express what comfort would mean to them.

Second is your professional, but transparent assessment of the current health or capabilities of their HVAC system in a non-judgemental way.

And the critical third piece is to take the vague and emotional “comfort” complaint and define it in terms you can successfully attain. “Your son’s bedroom will never be more than 1°C colder than your daughter’s room, as long as he keeps his blinds closed.”

H

ave you ever paid attention to how a duck moves across the water? Virtually noise free, it seems to glide with smooth, effortless movement with barely a ripple left behind. Below the water surface is where the mechanical work is done to propel the fowl.

There is an energy transfer required to accomplish this work. For a duck, the fuel source is the grass, seeds, insects and fish (depending on the breed). The webbed feet are the energy transfer mechanism, the distribution system.

Have you ever taken the time to observe the common wet rotor circulator performing its job? When it’s operating properly, it’s virtually noise free. You may not even hear it running when you walk up on one.

Electricity is the most common fuel source for it. This electricity is converted into mechanical energy. The volute and the body of the circulator are not unlike the undercarriage of the duck, and the impeller could be compared to the duck’s webbed feet. That’s the part where the magic happens: the transfer from electricity to fluid flow.

Properly sized and installed, a wet rotor circulator should provide years of trouble-free service. The fuel – the power source – needs to be correct, clean and stable.

Same applies to the duck. If a good fuel source is not available, the performance falls off. Plastic and garbage are not sufficient energy sources for ducks, or for any wildlife.

I enjoy the sound of the ducks and geese that land on our ponds, and the sound their wings make on takeoff. The way they arc their wings and quickly drop out of the sky to land is quite something. I love their water-skiing landings.

Take a break sometime and watch some ducks at work or play, but remember, if it walks like a duck and quacks like a duck…it’s probably a duck. If it moves fluid and spins quietly and effortlessly in a hydronic system…you’ve got yourself a circulator.

An ongoing evolution Much as circulators have evolved over time, different species of ducks have evolved to adapt to their habitats. The shapes and sizes of the wings, and the position on the body of the wings and legs have changed over time. The way a duck flies, swims, dives and walks varies from breed to breed, and its natural environment has had a lot to do with that.

HYDRONICS

Air and the impeller A common term associated with circulator performance, or lack thereof, is cavitation.

CHECKING ON THE ENVIRONMENT Without a clean, healthy food source, a duck will get stressed. In these situations, it may have to travel long distances for a suitable food source (its flow), and it may have to overcome winds and currents (head), and it will be affected by having to look for food in fresh water, salt water, clean water or dirty water (fluid quality is a factor for our feathered friends).

When a circulator fails, or doesn’t perform as expected, it is time to troubleshoot, and our duck’s search for food can help us define what our circulator is looking for as well. How much flow (gpm) is required? How much resistance (head) is created in the circuit it is serving? What type and temperature of fluid is required for the installation?

Clean fluid is critical for both ducks and pumps.

Thankfully, having clean fluid is an easily accomplished task in hydronics. Clean the system with a hydronic detergent, flush it, and then fill with clean, low mineral content water. You can gain additional peace of mind by adding hydronic conditioning chemicals.

The addition of an air and/or dirt separator with magnetic functionality is a good idea, as well.

The magnetic function on a dirt separator will protect electronic circulators by pulling micronsized metal particles out of the fluid in which they operate. This separation ritual should be applied to all hydronic systems, old and new.

Providing clean fluid for the ducks is not as easily accomplished. Ducks Unlimited and other groups continue to lobby and work to ensure we protect the wetlands. Runoff from farming and livestock operations, as well as industry, is poisoning ponds, lakes and streams, making life more difficult for ducks. And changing weather patterns, flooding, and droughts all effect habitat.

Consider volunteering or contributing to these groups to help ensure that the wildlife, and ourselves, have access to clean, safe wetlands.

Vapour pockets can form due to drop in pressure at the impeller below the vapour pressure. The noise generated is caused by the pockets, or bubbles, collapsing. These can make a popping sound, not unlike a bowl of Rice Krispies. Or, it can sound similar to pebbles or gravel passing through a pipe.

The force of cavitation can, and will, destroy the impeller if left unchecked. Flow will be reduced or stop completely when a circulator is forced into a cavitation episode.

Is it possible for cavitation to occur at the feet of the duck as it tries to accelerate for a take-off or evade a predator? I’ll bet you didn’t know that diving ducks actually run across the water to gain the speed necessary for takeoff.

Ducking danger Ducks sleep with half of their brains awake and can detect danger in less than a second. That helps to keep them out of danger and able to react when necessary.

With some of the newer electronic circulators, there’s a small microprocessor that stays awake 24/7 as well. These circulators also maintain a small flow rate, a few watts of power consumption, to be able to respond quickly to a change in demand, and keep the system out of danger.

Knowing the causes of cavitation in a circulator is critical for the hydronic technician.

The temperature/pressure relationship has been defined by the engineering community and termed as Net Positive Suction Head Available, or NPSHA. Modern Hydronic Heating 2nd edition has perhaps one of the best, understandable explanations of pump cavitation that I know of. That’s a classic text book that’s well worth adding to your 2020 reading list.

The

O

h, the lowly, unappreciated commercial kitchen drain, so often neglected, but what a load to carry!

When considering a kitchen’s capabilities, kitchen designers, facility managers, chefs and other personnel tend to focus on a commercial kitchen’s many appliances – the brand name out front, how big the equipment is, and how it is laid out. Granted, cooking is important in a large kitchen, but too often overlooked is one of the most important facets of keeping a busy kitchen operational and clean: its floor drains.

But consider the need for kitchen sanitation. Anyone who has worked in a commercial kitchen knows that every day food morsels, ingredients, and most every drop of sauce, soup or stew that doesn’t leave the kitchen on a plate or in a bowl ends up on the floor.

That’s why kitchens need to be cleaned between meals or, for food and beverage processing, as routinely as the need requires.

Making sure that floor surfaces are squeaky clean and free of bacteria and debris places great expectations on a kitchen’s drainage – to say nothing of the volume of water required to wash the floor and flush the drains, or the time to do it properly.

MATERIAL CONSIDERATIONS

AVOIDING CONSTRUCTION DAMAGE Drainage is typically sloped to one per cent from the drain and is anchored in place to become a part of the floor.

It’s important to protect it during the concrete pour, and the durable channel cover used should be left in place during all floor work.

46

M e c h a n i c a l

If you have worked in a professional kitchen, you’ll see a lot of stainless steel. From the doors on the fridges and freezers, to the prep tables and sinks, stainless steel is used because it’s extremely durable and easy to clean and sanitize. And that’s also the reason you’ll see it in the drainage systems in many kitchens.

Stainless steel drains, grates, drain channels and even P-traps are all available for use in commercial systems.

Stainless P-traps have the ability to withstand the very high temperatures of water that is dumped into them from large kettles, or used to flush the drain channels, as well as the surfactants (cleaning chemicals) that may also be used.

AVOIDING BOTTLENECKS When planning out the drainage needs of a commercial kitchen, or a food or beverage processing ing culations facility, there are some calculations that should be performed..

Sizing drain channels is a facet of the design tied directly to the volume of drainage required.

One of the most important nt functions of a drain is to get et waste material and water off the floor quickly. Drainage should never be a bottleneck. The sooner ner the floor is cleaned, and dry, the he sooner it’s safe to work on again.

Typically, a kitchen drainage system will use a fourinch drain and a P-trap. This meets the majority of flow capacity needs, although in some cases, a larger drain surface and channels are needed.

At larger facilities, the drains may be several square feet in size, with water and waste material flowing through grates – often stainless steel grates – into a broader and deeper channel for faster disposal.

Keeping the floor dry isn’t just a safety issue. Sanitation is very important, especially when considering the possible presence of toxic contaminants such as listeria, salmonella and e-coli – what I occasionally refer to as the “Big three.”

CLEAN, AND THRIFTY Some drains are designed specifically for use in the food and beverage industry, where maintaining hygiene is critical. Lacking corners or inside cavities to harbour bacterial growth and, with resistance to a wide range of cleaning chemicals, these drain systems are not affected by high-temperature cleaning, caustic cleaners and effluent, or steam disinfection.

One North American brewery that my company worked with took the opportunity to install a trench drain system suited to the beverage industry when it built its new 50,000 sq. ft. brewhouse, and the choice of drain ended up having a nice trickle-down impact on its bottom line.

In their old facility, employees would spend 10 to 15 minutes hosing down the floor after a tank cleaning to get all solids down the drain. With the drains in their new facility, most of the solids would make their way down the drain with little effort; an employee would only need to spend a minute or so cleaning up any loose ends.

With floor and drain washing being required twice a day, the new drains free-up half an hour of labour and save hundreds of gallons of water each day. Looking at that figure over the course of a year, the savings add up to be pretty significant, and have an impact on their ROI, simply by selecting the right drainage product.

Checking the channel An important consideration when specifying drains is the manufactured channel grade. All drains aren’t created equal, so be sure to compare the effectiveness of a drain’s ability to carry away wastes, and flush water.

Drains, especially those for larger kitchen, hen, brewing and food processing operations, may be 16 inches by 16 inches in size, some may be 20 by 40 inches inches, or even larger larger.

With that size of grate, they should be chosen for their strength and durability – in some cases with the ability to sufficiently tolerate the weight of a fully-loaded forklift.

They should also be easy to clean, ensuring that solids don’t get hung up in them. That’s why we suggest avoiding drains with square corners when sanitary conditions are an absolute must.

LOCATION, LOCATION, LOCATION Because the main purpose of drainage is to eliminate waste and flush water with a facility, it stands to reason that the best place for the location of drains is where the most water is — I’m referring not only to water dumped from kettles, but also water used to clean floors and flush the drains.

Many cleaning procedures involve the drainage of highly acidic materials, so the grade and formulation of stainless steel may be a consideration. And when cleaning, it’s best to avoid strong chlorine solutions, such as industrial bleach or sodium hypochlorite. Even stainless steel can oxidize, often looking like white blemishes. This will eventually weaken the material.

QUATTRO’S CORNER

Heading underground for inspections HA HAVING A BALL B

F

or this edition of Quattro’s Corner, we’re going to take a closer look at underground plumbing inspections.

These inspections can be difficult for some inspectors as not all connections are complete at the time of inspection.

I usually advise them to close their eyes and visualize.

When it comes to the plumbing underground sanitary and storm drainage pipe, there are generally three separate topics to consider: testing, materials and drains/vents.

Both the Ontario Building Code and National Plumbing Code provide multiple options for testing this type of 4” underground pipe.

Both codes say that a water or air test shall be conducted after a section of drainage system or a venting system has been roughed in, and before any fixture is installed or piping is covered, except in the case of an external leader.

The Ontario code also states a ball test shall be carried out on a sanitary building drain, sanitary building sewer, storm building drain and a storm building sewer buried underground.

The NPC makes a ball test an option at the discretion of the inspector, if requested.

48

M e c h a n i c a l

I am a big fan of ball tests. Why? Because they don’t lie and, in my opinion, they are the best test fo for slope on 4” underground pipes.

I constantly hear about municipalities allowing half a pail of water to be applied to the pipe as soon as the ball has been dropped. DON’T! If the appropriate slope has been applied and the drain installer thoroughly cleans the pipe prior to inspection, the ball should have no problem making it to its final destination without the benefit of any water.

To conduct a ball test, a hard ball dense enough not to float shall be rolled through the pipe. Under the NPC, the diameter of the ball must be 50 mm or larger for pipes 3” or larger, and 25 mm for pipes less than 3”. Under the OBC, the diameter of the ball needs to be 50 mm or more where the size of the pipe is 4 inches or more.

Pool balls are great for this and are relatively cheap to purchase; just make sure it is the same ball that was dropped for the test when catching it at the end of un. the run. nd water Air and tests are ptable acceptable natives alternatives sting but of testing they don’t ate if slope indicate aintained is maintained ugh the through ng. piping.

QUATTRO’S CORNER Checking the math, and the layout Getting the drain and venting sizes correct is very important. Typically, we have a bathroom group rough-installed in basements. In the photo below, we have an additional shower added to the bathroom group.

Place it in the right direction Piping materials, and how these materials are installed is rather straightforward when it comes to the OBC and NPC. Very often, it is hub and spigot type PVC SDR 35 that is installed.

Some inspectors are not aware that the codes state how the pipe shall be installed.

A length of hub and spigot pipe and pipe fittings in a drainage system shall be installed with the hub at the upstream end, so the direction of flow goes from the wide opening of the pipe to the narrow end. If the hub is installed backwards it leaves a sharp edge, creating an opportunity for items flushed down the drainage system to get hung-up on.

This is a common error made by installers.

Make sure that the writing on the pipe is installed faced up, and remove all the stone covering any connection so that the inspector reviewing your underground drains can verify that this requirement is met.

As per OBC 7.5.8.1.(2) and NPC 2.5.8.1(2), when determining the size of a wet vent, the hydraulic load, or fixture units, from the most distant fixture shall not be included. When the code states “most downstream fixture,” it is referring to the vent connection for the last fixture and not its location in the washroom.

In the photo, the toilet is the most downstream, therefore its FU rating is not applied when using Table 7.5.8.1./2.5.8.1. We do need to add the remaining fixture units, found via OBC Table 7.4.9.3. and NPC Table 2.4.9.3.

The hydraulic load for a vanity using a 1-1/2” trap is 1.5; the hydraulic load for a bathtub is 1.5; and the hydraulic load for a shower with one head is 1.5. If we add them all up, we are looking at 4.5 FU. OBC table 7.5.8.1. (or NPC Table 2.4.9.3.) in the image may be a little small to read, but knowing that the size of the wet vent is 2” and that it serves a water closet, take our word for it that Column 3 says that the maximum of fixture units drained to a 2” wet vent is 3. BUSTED! The photo exceeds 3 FUs by 1.5, so the shower needs to be installed downstream and be separately vented.

If you have any questions or a funny photo you would like to possibly see in an upcoming edition of Quattro’s Corner, feel free to send an email to Andrew at quattroscorner@hotmail.com.

Marketing

Telling great customer success stories S

torytelling is hardly a new concept in marketing. In many ways, it’s just another form of word-of-mouth advertising – the oldest tactic out there, and still among the best.

Building trust Content marketing has blown up in the past decade, with case studies being among the most popular and effective approaches to crafting these messages. This is primarily because they put the marketing language – those features and benefits about you – in an objective thirdparty voice.

A Harvard Business Review study of 34 million interactions between buyers and the content they read found that case studies had an 83 per cent completion rate. That was more than any other type of sales or marketing content.

Quality success stories give marketers a way to establish credibility and trust with potential customers by leaning on former customers to back up their claims.

By creating a platform to share our success stories, we’re giving customers another way to spread the word with us. And, in most cases, a happy customer is only too willing to talk.

Why stories?

Stories allow us to establish dramatic themes that connect our brand to people at a different cognitive level.

We all know that buying decisions are made by two areas of the brain: the head and the heart, as the saying goes. Most marketing content doesn’t relate to the buyer on an emotional level, yet studies show many of our buying decisions ecisions are ng as the made by the heart, ultimately, as long brain is satisfied.

Good storytelling will bridge that gap, pulling the heartstrings while fulfilling the brain-side needs.

It was a dark and stormy night… ght…

The good news is you don’t need to o be Alice e Munro or Stephen King to craft a compelling story. Here are seven ways to do it well:

1

Align with your marketing strategy.

Sometimes we tell the stories that are easiest, rather than the most strategic.

Brainstorm to get to the stories that connect with your business goals.

Trying to dominate a specific neighbourhood?

Be obvious in telling a story that proves you work in that desirable area. If your positioning includes expertise with old Victorian houses, get

54

one of those in there. If you promise “expect unexpected” levels of customer service, capture a truly phenomenal example.

Your marketing program should also have a solid search engine optimization strategy that has identified keywords and descriptions that will help you rank well. Find the case studies that allow you to embed that language.

2

Interview the people involved.

F Following the usual “problem-solution“ results” res formula about how your team fixed something feels, well, formulaic. A story is more compelling and an d re rela relatable ela lata tabl ta ble bl e wh w when en your cu customer is helping tell it, and when the employees involved are also featured with direct quotes about the experience.

This means taking some time to interview them, which is a skill unto itself. Be prepared with several questions to get them talking, listen carefully and probe.

If you can do the interview in person, so much the better to get to the heart of the story and make a connection that will help later when you ask them to help share the story.

Ask to record the interview so you can focus on the discussion and not how accurately you captured their quote in writing as they spoke. Later, when you’re writing the case study, you’ll have accurate quotes – although I wouldn’t be afraid to mildly paraphrase quotes from customers. As long as they approve the quote, they’ll appreciate your effort to help them sound a little better than they did on tape.

Marketing with DOUG MACMILLAN

Provide compelling visuals.

In today’s visual world, not only do we need a great image to drop on a blog, social media or email blast when we’re promoting a story, we also need to reach visual learners with images that tell our story rather than just accompany it. That means more than a nice picture of you standing with a happy customer.

Encourage and reward your employees when they capture before, during and after photos of projects using their smartphones. It might be an idea to consider holding an employee seminar about how to take a good picture – lighting, focus, resolution and such. A few pointers can make a huge difference.

Stories with a narrative, close-ups of the problem, and candid and unposed photos of the subjects will elicit higher engagement.

How many case studies do you need?

I say focus on quality over quantity. Telling two or three strategic, quality stories a year will still build a good library.

Also explore the various online tools that are available for creating quick slide show animations from your photos, or even infographics or illustrations that will help you tell the story. Some equipment manufacturers may also have visual content that can help you accentuate the story.

Video can also be used for really powerful stories. It may take a little investment, but for a good return. Video grabs consumer attention and is 50 times more likely to be shared. Creating quality video content is the subject for a whole other column, however, but suffice to say that some d go into it. thought should

4

Make e the headline line t. count.

A great case study tudy headline is more ore than the icing on the e cake. In many ways, it’ss the other way around. More often than not, the headline is all that is seen when hen the story is put into a social ocial media post or lands in n an inbox that only shows an email subject line. Get it wrong and people won’t be drawn in to read all about it.

The best headlines tell the whole story in 10 to 15 words. They are straightforward and avoid being too cute. They capture a problem that the reader can relate to, point to a result they hope to realize themselves, and/ or illustrate a distinctive competency.

And invite your customer to share their story. It can be especially effective to get customers to write a review on Google or the other review platforms you use. You can comment on their review with a link to your case study.

Not everyone is a writer, so crafting a good case study could be intimidating if it’s not your forte. Fortunately, finding a good freelance writer is pretty easy and affordable.

Look for someone who isn’t necessarily a marketer, but has a professional communication, news writing or journalism background – objective storytelling isn’t ad writing and you’ll want someone who knows how to structure a good article.

And once crafted, create a printed version of a success story to use as a leave-behind in sales calls, or for strategic use during follow-ups to sales calls.

NATURAL REFRIGERANTS DRIVING INNOVATION The spread of natural refrigerant systems into industrial cooling is further proof of their viability across the gamut of refrigeration markets and applications.

From low-charge propane in stand-alone systems, to a variety of CO2 architectures in food retail, to the introduction of CO2/NH3 systems in cold storage, the market continues to seek the advantages that natural refrigerant systems can provide.

As manufacturers continue to answer the call, look for naturals to be featured in more refrigeration system innovations in the coming years.

NATURAL REFRIGERATION FOR COLD STORAGE

NEW DIGITAL MANIFOLD

REFMATE

Meeting high-tonnage, cold storage requirements while addressing the known operational challenges of ammonia and CO2 meant that manufacturers had to expand upon the existing cascade architecture.

The CO2 portion of the system uses high-pressure, reciprocating compressors and a heat exchanger as a condenser, where the NH3 chills and condenses the CO2 into vapour. The cooled air is then pumped into the facility’s ductwork, keeping the NH3 stage isolated on the roof and leveraging the non-toxic natural CO2 to deliver hightonnage refrigeration in the conditioned space.

LOCKABLE FOR LONG-TERM MEASUREMENTS

To help alleviate potential ammonium carbamate concerns, the CO2/NH3 helix style heat exchanger features stainless-steel construction. This material was chosen for its corrosion resistance and expected service life.

The NH3 portion of the cascade system provides the high stage of the refrigeration cycle, using a small-displacement, very low-charge, single-screw compressor and a condenser that sits on top of the unit and uses ambient air to cool it. This design meets the lowcharge NH3 requirement (fewer than 100 pounds) while keeping the NH3 stage completely separate from conditioned space.

Multiple helical coils have been used in the compact space of the design. This is so that expansion and contraction of the tubes during large changes in temperature and pressure result in very low levels of strain and stress, thereby reducing the risk of failure and leaks while delivering a large heat transfer surface in a small volume.

The self-contained, modular unit essentially serves as the system’s mechanical room, and

THERE’S AN

App

FOR THAT!

B

efore the age of cell phones, techs were given a pager and a roll of quarters. When that pager went off, they had to look for a payphone to call the number shown. As the cell phone evolved, the “brick” was all the rage to carry in the field.

For those with home computers, hopping on the internet in those early days meant dial-up service using the likes of AOL – that company that gave away CDs by the bucketload and spawned the rom-com You’ve Got Mail. Back then, we thought the future was NOW!

Of course, in those days before the smartphone, if a technician encountered a problem or had a question regarding a piece of equipment on a jobsite, the only option was to muddle through it and hope that they guessed right.

On older R22 equipment, this kind of guesswork created the old adage “Beer Can Cold” – something that proved somewhat effective at times, but it was more of an art than a science.

With the introduction of more efficient equipment, the rules of thumb of yesteryear are no longer relevant to today’s technician.

The more in-depth the equipment, the greater the need for better diagnostic tools and charge adjustments. This leaves little room for guesswork and makes the smartphone one of the most important tools on a technician’s toolbelt.

A WORLD IN YOUR PALM Practically every HVAC manufacturer has designed an app to help technicians find the correct part number for the parts needed while in the field. These apps are also designed to assist techs with troubleshooting tips for these parts and/or equipment.

Tech savvy techs can also use many manufacturers’ apps to refer to wiring diagrams, installation manuals, service bulletins and various other documentss that nds would have been long-lost back when a cell phone weighed a couple of pounds and cost as much as a used car. ace Some manufacturers have even gone as far as enabling a tech to set the furnace up and diagnose failures all via the app on their phone.

As techs are relying more heavily on their smartphones for information, more and ht more apps are being introduced to help them ensure they are making the right ed parts, diagnosis (rather than relying on an educated guess) as well as finding required ou’re on a we thought we’d put together a list of a few that might help the next time you’re jobsite with a roll of quarters looking for a payphone.

“If a technician encountered a problem or had a question regarding a piece of equipment on a jobsite, the only option was to muddle through it and hope that they guessed right.”

HVAC ON THE TOOLS APPS An app that we’ve found to be very helpful is the Bitzer Refrigerant Ruler. This app allows the user to easily and accurately convert temperature to pressure for a variety of different refrigerants.

Users can adjust the dew and boiling points, based on the elevation where the equipment is installed. The app also contains data and information on more than 100 natural and synthetic refrigerants, as well as links to relevant documentation online.

Another compressor manufacturer, Emerson, offers a range of helpful apps that can be used to diagnose different parts of cooling and heating systems as well.

For example, the AE Bulletins app offers information on liquid refrigerant and air conditioning systems, as well as terminal plate connections for dual winding compressors. They also offer a fault finder app that allows technicians to troubleshoot all of Copeland’s compressor protectio protection systems. The company’s W White-Rodgers mobile app allows technicians to search for approved replacements for several different OEM parts.

HVAC Check & Charge is another Emerson app that was launched to help technicians calculate superheat, subcooling or the airflow. Check Charge allows the tech to plug numbers into the app to confirm their diagnostic conclusions.

Not all helpful apps come from equipment manufacturers, however.

SuperCool is an all-around app that is designed to confirm a technician’s findings while keeping different formulas, such as calculations for sizing a belt, building a capacitor or verifying resistance in the circuit, within easy reach. The app also includes several troubleshooting tests and a number of conversions and reference charts.

The MeasureQuick HVAC app is as close to a “one-stop shop” as a technician can get. This app has an education section with information pulled together from a plethora of sources. It also includes links to such websites as HVACRSchool.com and industry blogs to offer technicians educational sources at their fingers. From what we have heard, they have also started to beta test a version of the app for coolers and freezers.

Currently, the one downside to this app is the need for compatible Wi-Fi tools that can access the app. To-date, not all field tools are Wi-Fi compatible. This is sure to change in the near future, however.

APPS DONâ&#x20AC;&#x2122;T TRUMP With all that can be said about apps, and no matter how the systems change, or the tools designed by manufacturers make a technicianâ&#x20AC;&#x2122;s job easier, there is never a substitution for proper training of your trade.

training app and properly interpreting the outcome is what makes a great technician. d As todayâ&#x20AC;&#x2122;s HVAC industry advances farther and farther into the high-tech realm, to become a great technician, one needs to embrace the technology or risk being left behind.

These apps are great tools to add to a technicianâ&#x20AC;&#x2122;s toolbox, but it is important to remember that the most valuable tool in that toolbox is the education and knowledge gained through practice. Without that, inputting numbers into an app will provide the technician with results that the technician may still not understand.

HYDRONICS B y Andre w Sn o o k FUEL STORAGE AND EXTRACTION FOR

biomass boilers oody biomass fuels have grown in popularity as an environmentally friendly option for commercial and residential boiler systems across Canada, especially in areas where natural gas is not always readily available. But fuelling boilers with woody biomass comes with fuel handling and storage needs that are unlike other fuel options.

W

Daron Thomas, president of Fredericton-based Thomas Industrial Sales, a company that specializes in green building projects and biomass-fuelled boiler systems, offers his insights into best practices for storage, extraction and safety when it comes to operating boilers with pellets, chips and other woodbased biomass.

“In a perfect world, the silo would be empty all summer long.”

DIFFERENT FUELS, SOMEWHAT DIFFERENT STORAGE WOOD PELLETS: Hardwood od and softwood pellets are a common fuel source for many y biomass boiler systems. They y offer a stable price and are fairly simple to store in a typical grain silo. That said, there are suggested storage procedures that should be followed.

“The only advice we give to our customers is to not store through the summer with any quantity of pellets in the silo because they could combust,” Thomas says. He suggests burning off the remaining pellets before the end of the colder months.

“If the silo is full, the ones at the bottom will be crushed over the summer simply by the sheer weight of them. And once it becomes sawdust, it doesn’t burn, it won’t work,” he explains.

“In a perfect world, the silo would be empty all summer long.”

WOOD CHIPS: Wood chips are typically stored in chip boxes. They do not have the same combustion risks as wood pellets, but they can still pose a fire hazard.

“If the space is too warm, they could start a small, low-grade fire,” Thomas warns. “We like to recommend that there is no fuel left in a pellet silo or a wood chip box [over the summer].”

While pellet silos are naturally ventilated, the chip boxes always require some cross ventilation. This helps remove any existing moisture from the chips, which are sometimes delivered cold and wet, and could lead to freeze-ups. By removing some moisture, the boiler can process the wood chips more efficiently.

THE FUEL

There are a few different types of extraction and auger systems that can be used for biomass boiler systems.

SPRING OPERATED EXTRACTION SYSTEM Application: Extraction of pellets and wood chips from the fuel silo to the boiler.

Function: Generally used with small-volume bunkers and boiler systems with smaller output levels, two extraction arms made of spring steel sweep the fuel onto an open face extraction auger. This extraction system is suitable for square and round fuel bunkers.

As long as the silo is full, the spring arms are closely attached to the centre plate. A die spring extraction system can be mounted perpendicular to the silo floor or on an angle up to 15 degrees. A wooden intermediate floor has to be field supplied.

HORIZONTAL EXTRACTION SYSTEM Application: Extraction of pellets and wood chips from the fuel silo to the boiler.

Function: Used for bigger bunker or silo volumes, this heavy-duty floor-stirring device has two sweeping arms consisting of either one or two (depending on extraction diameter) joint arm(s) and a spring steel extension, which is positioned at the outside of the arms. Activation of the stirring device is controlled by optical sensor. The extraction auger itself is engaged by its own drive unit, which works independently of the stirring device.

A cover plate for the auger channel is necessary if the system is run with wood pellets. And the system can be mounted horizontally or on an angle. A wooden intermediate floor has to be field supplied.

FUNNEL EXTRACTION SYSTEM Application: Extraction of pellets and wood chips from round silos to the boiler.

Function: The fuel extraction is conducted by a stirring auger positioned in the centre of a steel funnel. The auger is mounted on a heavy-duty cross joint. If the silo is still fairly full, the auger extracts from an almost vertical position. As the silo empties, the more the auger will extract on an angle. The maximum extraction angle is determined by the funnel.

The auger is driven by a worm geared drive unit, which is mounted on the stirring device. In case a compression of the wood fuel occurs, the auger will change the rotation direction for a certain amount of time to loosen the fuel up and to avoid a fault message.

WALKING FLOOR EXTRACTION SYSTEM Application: Extraction of pellets and wood chips of large silos to the boiler.

Function: Hydraulic driven pushrods with attached scraping wings are being moved back and forward, which pushes the wood fuel towards a lower-lying extraction auger. The walking floor can also be ordered with a filling function.

In some cases, it might not be possible to fill the silo completely due to accessibility constraints. The walking floor with filling function has two separately operating sections (with separate pushrods). The first section makes sure that the fuel is pushed towards the middle of the silo, while the second section pushes the fuel onto the extraction auger.

KNOW YOUR BIOMASS ASS SYSTEMS There are a number of key components of woody biomasss systems.

The extraction auger for pelletss delivers wood pellets to the boiler and is designed to work with a square-shaped fuel silo. ed wood The pellets roll down the angled d boards onto an open auger channell and are sent towards the boiler.

Trough conveyor augers are very robust pieces of fuel transportation equipment that can be used for all usual wood fuels. The only limitation is the restricted incline angle on which this piece of equipment can be mounted.

Pipe conveyor augers are suitable for all usual wood fuels, but are usually used for inclined angles that cannot be covered by the trough auger.

The rotary valve is used to securely separate the boiler and fuel silo from a fire prevention point of view. This is used if negative or positive pressure is expected in the fuel silo.

A fire prevention device, a sluice valve is mounted directly above the infeed auger in order to mechanically separate the firing mechanism from the fuel silo.

By John Barba

Comparing AC to DC A common AC permanentt or split capacitor (PSC) motor uses AC electrical power to magnetic create a rotating electromagnetic onary field in the stator, or stationary nduces part of the motor, which induces tor, a magnetic field in the rotor, located inside the stator.

UNDERSTANDING

ECM CIRCULATORS ECM

d The magnetically-induced h rotor spins to keep up with the stator’s rotating field, but ng because the stator’s rotating e rotor, field rotates faster than the ts in power “slip” occurs, which results loss.

Also, to vary the speed of the rotor, the voltage is ay “chopped,” throwing away unused power.

An ECM is a brushless motor with a permanent magnet rotor and a microprocessor-based controller. Because there’s a permanent magnetic field in the rotor, there is no time delay needed to induce a magnetic field, so the rotor spins as fast as the stator’s rotating field, which means there’s no “slip” and, therefore, no power loss.

DC power fo for these circulators comes from standard AC power that’s transformed into DC power within t circulato so there’s no need for a transformer, a the circulator, battery, or a any other device.

motor technology has taken the plumbing and mechanical, radiant heat and HVAC industries by storm. If you haven’t installed led ECM equipment yet, there’s no better time. me.

DC power is controlled in ways unlike AC. This permits precise speed control to produce p exactly what a system needs, resulting in less power consumption.

Smaller, super-efficient, permanent magnet net motor circulators and pumps are now, in some instances, less expensive than the older, tried and true products.

As such, ECM circulators save electricity.

Some can use up to 85 per cent less electricity compared to a circulator with an AC motor. This can represent a considerable savings in energy costs.

That’s good for residential applications, and really good for a commercial application with numerous pumps.

Offering electrical efficiency, precise control, and a beneficial impact to total hydronic system efficiency, an ECM circulator ulator is the most technologically advanced circulator on the market.

ECM, short for electronicallycommutated motor, technology has won admiration by trade pros, system designers and building owners worldwide. They’ve longsince passed through the “wait n’ see” stage.

It’s the pump of tomorrow for use... today.

Bu But more important than greater electrical efficiency, E ECM circulators are better controlled than AC circs. Because B of their internal motor control, they can be b programmed to precisely match the requirements of the system. This results in much i greater overall system efficiency, which is the goal.

Whether zoning with circulators or with zone valves, an ECM variable speed circulator will make the overall system run more efficiently and last longer. Over the years, those savings add up.

DIDYOUKNOW? ECM motors are also referred to as BLDC, or brushless DC electric motors.

afal Hryszko, a technician with Canada Climate Services in Hamilton, Ont., had his heart set on donning a completely different kind of uniform and tool belt before he had his head turned by the mechanical trades.

“I was completing my criminology degree at university in the hopes of pursuing a career as a law enforcement officer,” he says. “Given the tough hiring process, I decided to go to college to get a trade under my belt just in case it took a long time to get hired by the police.”

Rafal Hryszko: To protect and serve Not sure which direction to take at trade school, his path was helped when someone mentioned HVAC. “I had never even thought of it as a trade in the same mould as plumbing and electrical and, being young and never having owned a home, I didn’t realise how important of a trade it is,” he reflects. “There will always be a need for heating and cooling.”

Before he completed his last semester of school, he was on the tools as a helper on mechanical jobs, working on boiler installs and maintenance.

“As the fire and passion grew and I began to learn more, I soon found myself in my own van and working with little supervision,” he says. “I never knew this would be the actual dream job and I am blessed for all the opportunities and people I have met along the way.”

AND OTHER ICI TALES

B

ack in 1976, the Montreal Canadiens started their reign of domination with four Stanley Cups in a row. Being a Bobby Orr/Boston Bruins fan, and later a Toronto Maple Leafs fan, I hated them.

I bring them up because memories of them bring me back to a day when I was 17 and first employed as an apprentice working for Don Vanderlinde and his small company, Lind Plumbing, in London, Ont. While driving to jobsites in the countryside, I used to bet with my journeyman, Steve Boyd, on baseball and hockey. I always went for the Boston teams and he would constantly beat me with the Yankees or the Canadiens. Those first few weeks bring back many memories, and one of them was a hospital we worked in.

I was young, and not too bright plumbing-code-wise, so they would give me the typical all brawn and no brains jobs – actually, my 27-year-old journeyman was a hard worker. No job was too hard for him, and he would lead the way when it came to physical stuff.

Of course, this particular tale happened so long ago that my memory may not be as accurate as it could be, but I’ll share what I remember.

We were called in to do a renovation in a hospital somewhere near the town of Strathroy. From my recollection, it seemed to be a hospital for the intellectually disabled and people with mental health disabilities, or at least one wing was. The other wing was for the criminally insane.

I believe we worked in both wings, however the wing for the intellectually disabled was closed while under construction.

While working in the non-criminally insane side, it was kind of fun.

Most the patients were very pleasant and young in mind and heart.

Thank goodness I didn’t meet the other wing’s patients, but we did renovate the institute’s showers and bathrooms.

To be honest, most of what I can remember is carrying tools down long hallways, using sledge hammers to smash out old thick-tiled bathroom walls, removing plumbing, and cutting and discontinuing copper water supply lines to these old rooms, but there are some things that have also stuck with me, especially the detox or floor toilets.

HOSPITAL CONSTRUCTION GOES DIGITAL I recently took my fourth-year plumbing apprentices through the ongoing construction of the new Medical Cancer Centre in Calgary. Modern Niagara was kind enough to tour us through the building being developed by PCL. We were not allowed to take pictures; however, it was an educational experience to witness the level of detail and expense that is taken to ensure potable health protection for the public.

Technology has developed so much that they employ 3D digital designers to completely digitize the whole hospital. It was fascinating to see cutaways of all the piping systems rendered in 3D, including all digital data recorded for each piece of equipment.

As the project advances, RFI forms are taken and changed digitally, which helps with the quality of the build that ultimately helps with the prevention of disease, and the protection of our health systems in hospitals.

AVOIDING DEAD LEGS

THAT’S NOT A FURNACE GRATE If you ever find yourself in a secure facility that houses prisoners, you may not enjoy your first bathroom experience – something that I’ve learned by installing fixtures, not taking up residence.

When I set the scene for someone, I tell them to think about those prison movies where you see the new inmates come in, undress and get hosed down or showered. That’s the easy part. The fun part happens in a separate bathroom that has a one-way mirror and what is called a floor toilet.

This particular type of toilet looks something like a heating floor register, but it doesn’t blow heat. As a matter of fact, quite the opposite.

The inmate is instructed to squat over the register (floor WC) and attempt to remove any possible goodies he or she might be concealing in their backside. Many attempts have been made to conceal various items, some too creative to include here, but let’s just say that money, drugs and weapons are on the list of contraband.

Once the goodies are “extracted,” the waste and evidence would be trapped in the floor toilet, and the register like fins would be closed remotely by someone behind the one-way mirror to prevent any tampering with the evidence.

I’m not sure who had it worse, the inmate or the security guards.

ON THE HOME FRONT Not just a concern with commercial and institutional projects, the risk of legionella and other bacterial growth has been a consideration with residential hot water tanks that have an operating temperature of 140°F. That’s hot enough to cause scalding, but helps prevent bacterial growth.

The use of thermostatic mixing valves can help reduce the temperature of the water delivered at the tap while maintaining a higher storage temperature in the tank.

Around the same time as my hospital project, another ICI plumbing and mechanical story was emerging. A conference of 2,000 Legionnaires was held at the Bellevue-Stratford Hotel in Philadelphia, and a number of men between the ages of 39 and 82 had contracted a disease (later called legionnaires disease) caused by Legionella pneumophila bacteria.

After serious investigation by the local health department, it was discovered that the source of the problem originated in the hotel. It was later isolated and identified by finding it to be breeding in the cooling tower of the hotel’s air conditioning system.

Back then, cooling towers rarely had screens protecting them from bird feces.

This waste would drop in and cause bacterial growth, and these diseasespreading microorganisms would then be blown and spread throughout the building.

This has caused major concern with plumbing and heating systems throughout the world since that time.

When hot water cools down to 105°F to 115°F, it has a greater chance of forming legionella in small amounts.

As such, when water lines are cut and dead ended, you can’t just cut and cap the never-to-be-used-again drop pipes from the ceiling in the renovated room. If you do that, when water rushes down the mains in the hallways, the existing or partially deleted hot branches will cool down to that warm danger-zone temperature.

Since that famous outbreak in Pennsylvania, we have insisted that in hospitals, and with other commercial and institutional renovations, deleted hot lines must be deleted with a shutoff, short nipple and cap in the hallway.

In addition, cooling towers must now have screen protection from any bacteriaforming disease which may enter it.

Where did the

PROFIT

GO?

D

id you ever find yourself at the end of a job asking, “Where did the profit go?”

You know how the process goes: you were invited to bid, you reviewed the drawings and scope of work, you analyzed the material and time requirements, as well as any potential variables. You put it all together and then added a little something to make it all worthwhile, and then analyzed it again before submitting with confidence that this project, when awarded to you, will be profitable.

Fast forward a number of months, or years, and you are left scratching your head. What happened along the way? Did you learn about something late in the job, or at the end of the job, that has not only resulted in the profit disappearing, but has left you lucky to break even?

As any prudent owner or manager would do, you go through the steps again trying to determine where things went wrong. It’s not your first rodeo, and you checked and rechecked all your figures. You worked at getting the lowest price on the materials used, but somehow the labour budget has exceeded your original budget, including what you added as a reasonable buffer.

This is a scenario that happens time and time again, even to the most experienced organizations small and large, and it happens on retrofits, remodels and in new construction.

But how does this happen? Where do things tend to go wrong? Let’s look at a few ways that projects turn from black to red on the balance sheets.

LABOUR CREEP, AND OTHER COSTS In most cases, project cost overruns come down to what should have happened rather than what has happened.

Not too long ago, I was on a jobsite meeting with a developer for an old factory that was transitioning to luxury lofts. While waiting for the developer, I witnessed three plumbers working together to resolve an issue.

An old lag bolt was in the way and had to be removed. Due to the age of the building, it proved to be quite a challenge. Different tools were tried before the use of a torch finally released it from its previous home. The result: three lost labour hours at a cost of $75 per hour – and this was just a typical Monday morning.

Of course, this was something I was told cannot and will not be billed as an extra.

Changes happen; project managers do their best to account for many different variables. Be they environmental updates, different courses of action or unforeseen problems, there are some that cannot be estimated with certainty.

The focus is always on what we feel are the controllable costs, and that puts the target mainly on materials. You work at getting the best price possible to provide some insurance for profitability, however, that singular focus can have many flaws, as you may have found out the hard way.

The question is, what do you do to mitigate any changes during the project, and more specifically, labour hours?

BUSINESS MANAGEMENT

Sharing the complexity and risk

Pouring labour into gaps

One of the first places we usually look when trying to keep costs in check is with the products we need for our projects, so let’s visit the procurement process. The typical method is to send the list to a few of your favourite wholesalers and ask them to battle it out until you are certain they have sharpened their pencil enough so that nothing is left on the table.

Good strategy? Well, let’s put ourselves in the wholesaler’s shoes and see.

The wholesaler’s purpose and area of expertise is in supply chain and logistics. Ensuring that their profit margin is razor thin only serves to pass certain burdens back to you.

If engaged properly, the wholesaler can be your partner in managing the job, reducing delays and making sure you have what you need when you need it.

They can prepare the product you need in organized batches, therefore, saving time and effort on the jobsite.

This requires project management from their end, as well as working with the contractor, to understand their needs and timeline. Unfortunately, when margins are razor thin, the additional service of project management or bringing in inventory can be viewed as an added cost that has to be eliminated. This can result in undue delays, rush orders that may create errors, chargebacks for holding up the project, and so forth.

When product arrives late, or incorrect items make their way to the jobsite, how do you manage it? With those expensive lost labour hours, of course. This not only increases your costs, but everyone’s frustration and stress levels, further reducing productivity.

Now a domino effect has been created. At the same time the wholesaler is trying to figure out how to make a reasonable profit to provide the service level the contractor expects, and they end up having to challenge the manufacturer to reduce their price.

This is a problem that works its way down the line. Over the past few decades, everyone has worked at cutting out the fat, reducing packaging, efficient transportation, increased production efficiencies, and the list goes on. All that is left is the reduction of quality and looking to cut corners in workmanship.

That five per cent discount that you fought hard for up front can actually end up costing you 10 per cent or more; if the belt tightening results in non-productive time for your crew on the jobsite.

The most important negative impact on a business, and the one that is most often responsible for disappearing profit, is lost labour time.

One of the biggest challenges today is finding and keeping qualified people, and this is a challenge in every department, from the back office to the jobsite. Of course, even with great people in place, straining employees mentally and physically will cause productivity loss.

If they are struggling with an installation, dealing with substandard products that may not stand up to the task, or having to be called back to deal with failures, expect this to contribute to their level of frustration.

Dealing with delays and staying on top of the supply chain to make sure they get their product on time adds to their stress.

Remember, that supplier you received that extra discount from is trying to reduce their costs as well, so they may not have the resources to go above and beyond to save the day for you.

Unfortunately, the cycle keeps repeating itself because, “It’s the way we have been doing it for years.”

While it is important to try to be efficient onsite, and to get your team to do things that seem to save time and money, sometimes pushing for the lowest price has unforeseen consequences. Think about your own business; which projects do you put priority on, the ones that are break-even, or the ones that you make decent money on?

When there are a few extra percentage points for your project partners to play with, it makes it much easier to cover gaps when they come up.

BUSINESS MANAGEMENT

Some costs hide in plain sight Sometimes we provide tools that seem to make a job easier, but some of these create other inefficiencies.

For example, let’s look at power tools.

We all like the big tools. They give the perception that you must be a pro to use them, but sometimes the big drill could be swapped out for a smaller one that does the same job – without the wear and tear on the tradesperson.

While some tools have taken away the pain from one area of the body, they could create it in another due to weight or trying to use it in tight spots.

With pro-grade tools, we have to think about required maintenance and calibration, batteries, and everything else that comes up with them on a jobsite, like charging, cold weather issues, replacements, and not to mention where to plug them in.

We once calculated that the use of a particular power tool on a project added $185,000 per year to the cost of the job just in lost labour time.

Hard to believe, but when you have 25 tools on a job that all require care, maintenance and calibration, you

would be surprised what a mere 15 minutes a day will add up to over the course of a year.

At the same time, we have our expensive tradespeople manually making solutions on site when engineered (and certified) products exist.

Whether it’s using scrap pieces of wood as a support bracket, or using a zip tie to secure pipe, or maybe the allpurposeful threaded rod that is used to make brackets in an attempt to secure heavier and larger items like cast iron

Finding solutions So how do you mange your largest variable?

Start with partnerships. Manufacturers and wholesalers can provide expertise with benefits and solutions to meet the unique needs of your projects. Talk to them and understand that things work best when we are all working in harmony.

Look at the new technologies and improvements that are created on a regular basis to address the needs of the market.

Whether it is to address qualified labour challenges or improvements to safety and efficient use, every year brings advancements in the materials and tools we use.

It was not so long ago that the only accepted plumbing method was copper pipe and sweat fittings. Now PEX pipe dominates as the material of choice for

92

M e c h a n i c a l

potable water delivery. That change created an easier and safer installation method allowing for time savings and the ability to take on remodel projects with minimal modifications.

Let’s not forget that continuing education and training is important. Investing in your team will pay dividends in improved workmanship and habits.

Simply said, easier and safer installations make for better quality installations, a productive environment and, in the end, the profit will be exactly where you put it in the first place.

pipe or suspended water heaters, these all contribute to productivity losses.

While the incidentals that are used to create these make-shift solutions seem inexpensive, the perceived savings is usually eclipsed by the cost of the labour it requires to make them, not to mention the lack of guarantee that it will meet the safety and code requirements which, in the end, creates unnecessary liability.

seasons nterest in heat pump technology has made this a growing segment of the Canadian HVAC marketplace.

Part of the growth can be attributed to the push to electrify heating and cooling systems in many parts of the country and, with the price differential between a traditional air conditioner and a heat pump being relatively modest, many consumers are willing to spend a little more for a system that can help navigate summer, winter and the shoulder seasons in between.

To take a look at how these systems are built, we took a trip to the Goodman factory in Waller, Texas. The 4.2-million sq. ft. facility is one of the largest HVAC manufacturing plants in the U.S., employing some 7,000 highly skilled and trained professionals making heat pumps and other HVAC products for delivery throughout North America.

Hitting the

sweet spot H

omeowners feeling overheated or getting the chills often assume that their furnace or air conditioner is to blame, reaching for the thermostat to get the temperature just right. However, temperature is not the only factor that impacts the comfort levels of a building’s occupants.

Relative humidity (RH), the amount of water vapour present in the air expressed as a percentage of the maximum amount that the air can hold at a given temperature, has a significant role to play in the comfort equation.

STAYING IN THE ZONE The Canadian climate makes it impossible to find a onesize-fits-all humidity level. The optimal range usually falls somewhere between 30% and 60% RH, but the colder the outside temperature, the less moisture it can hold. When this air is brought into a building and heated, the RH level can fall substantially, so humidification is necessary.

“The dry air that accompanies winter can cause a variety of health issues, from dry skin, dry sinuses, and increased allergy and asthma symptoms,” says Allen Haybarger, president of Canadian General Filters.

Moreover, getting RH levels right not only helps keep people comfortable and healthy, it also helps to prevent the premature deterioration of the buildings they live and work in.

“In the summer months, the reverse is true. Humid air that accompanies spring and summer leads to mildew, odours, spores and bacteria that require use of both de-humidification systems and UV air purifier solutions.”

PLAYING DETECTIVE When visiting a customer’s property, a tech should look for telltale signs of improper indoor RH levels. These could include condensation on windows, static shock, peeling paint, warped, cracked or bowed woodwork, and rot, mould or mildew growth. They should also take the time to talk to the customer about any health issues that could be caused by the environment.

Marlee Spiegelberg, product manager

with commercial and industrial humidification device manufacturer Condair, says that while high humidity has obvious effects on a building, an RH level that is too low can dramatically impact the health of its occupants.

“Increases in skin flaking, cracking and wrinkling is something we all experience in dry conditions and can result in skin inflammation, which may not always be visible. In dry air, our

M e c h a n i c a l

B u s i n e s s

skin can recognize the harsh environment and responds by synthesizing a stress hormone and immune system inhibitor called cortisol. Elevated cortisol levels in our skin and in our blood can interfere with deep sleep and suppress our natural immune response.”

Spiegelberg also notes that dry air negatively impacts the eyes and respiratory system. It also works to shrink infectious viruses, allowing them to stay airborne for longer.

Tom Ruse, marketing communications manager at Aprilaire, a manufacturer of indoor air quality products, adds that while air conditioning systems can handle some of the dehumidifying load in summer, there are many areas and conditions where the AC alone will not keep up.

“High humidity conditions in basements or crawlspaces, or where water tables are high in lake and coastal regions, often require dedicated dehumidification in addition to the air conditioner,” he says. “Plus, there are many times when the air conditioner may not run often enough to dehumidify.”

HVAC SELLING THE BENEFITS OF CONTROL Highlighting to the customer the benefits of adding equipment that can control indoor humidity levels can help a contractor add additional value to their sale. Older customers, those with young children, or sufferers of health conditions such as asthma could all benefit from having more control over the humidity level in their homes.

RIGHT FROM THE START It is important that designers of heating and cooling systems take the management of high and low humidity into account early in the project.

“The role of an HVAC contractor has changed a great deal in recent years,” says Haybarger. “Beyond looking at the HVAC system, homeowners look to you as an indoor air quality consultant, ready to discuss additional components that improve their comfort and health.”

“Every HVAC designer takes into account the need to limit humidity in the cooling season, but not enough consider the need to maintain a minimum relative humidity in the building,” says Spiegelberg. “This mentality is starting to change as designers and their customers realize that low relative humidity is neither healthy nor comfortable.”

Aprilaire’s Ruse says designers should include dedicated accessories as part of an HVAC system to ensure RH levels are kept in check.

“A dedicated supply-side ventilation system certainly can help,” he says. “To be truly effective, however, dedicated whole-home humidifiers and dehumidifiers are the best approach for any region of the country.”

Pat Tessier of Honeywell agrees, explaining that accounting for humidity early on in the design phase makes managing humidity levels easier in the long run.

“A properly designed HVAC system should allow users to maintain proper RH levels,” he says. “The system should be designed to meet the regional environmental factors. For example, northern Alberta has a much drier climate, so the ideal RH levels may be different to the standard 40%.”

“It is easy to justify the benefits of humidification when you can put a number to it in terms of product yield, product quality and process efficiency,” says Condair’s Spiegelberg. “Humidification for health and occupant comfort is a little harder to quantify.

However, more and more publications are coming to public attention that list the crucial benefits of humidification not only for occupant comfort, but for important health reasons as well.”

“Utilizing moisture meters and hygrometers alongside an RH chart to show homeowners what the humidity levels are is a very effective approach to illustrate humidity problems,” notes Ruse.

And don’t forget: as more equipment is installed, opportunities for home service contracts grows, too.

“Service techs can help customers better manage humidity by considering three strategies: adding RH sensing with control strategies, upgrading humidifiers and suggesting properly sized AC equipment. Regular quarterly servicing can also ensure proper operation of the equipment,” adds Honeywell’s Tessier.

The Psychrometric Chart is a powerful tool that allows HVAC engineers to perform heat load or cooling load calculations and determine resulting relative humidity conditions.

Mike Rowe STILL DISHING THE DIRT

A

lmost a decade ago, television host-turned-guest Mike Rowe shared insights into the importance of the trades in these very pages (September/October 2012). Now that we’ve turned the calendar to the 2020s, we thought we’d ring him up again to see if much has changed since we last spoke about the nobility of hard work, the willingness to get dirty, and perceptions about the skilled trades and their importance to a truly functional society.

If you speak to almost any business owner in the mechanical sector, it’s not difficult to get them to admit that finding skilled tradespeople is a challenge, and this skills gap can be tied to some of the perceptions that are held socially about what are, in reality, good-paying jobs that keep society functioning.

Photos by Michael Segal

“When you are trying to change the way a person or community feels about the definition of a good job – and that’s really what we are talking about: the vocations we immediately assign relevance and celebrity to – it is very, very difficult to quantify success,” says Rowe.

102

To help turn the tide, Rowe’s foundation, mikeroweWORKS, started its Work Ethic Scholarship Program in 2012 to help those who

M e c h a n i c a l

B u s i n e s s

were looking to buck the idea that a college or university degree was the only path to success.

“I didn’t have any stories to tell in 2012,” he says. “Today, we have hundreds of success stories.”

Shared each week on Work Ethic Wednesdays, the organization recognizes individuals who, a few years after getting a Work Ethic scholarship, are now making a difference in their trade of choice.

“Those stories are really important, not just because an individual did well,” says Rowe. “They are important because they make me much more persuasive when I’m talking to a guidance counsellor or a concerned parent – or a magazine editor who wants to know, ‘Are things changing?’

0 4 . 2 0

“It is not fashionable to talk these days about the importance of work ethic, the importance of attitude or delayed NYH[PÄJH[PVU but a basic understanding of those things is still, in my view, the best way to make yourself attractive to an employer.”

“The good news is, yes, I can give you 867 examples of how they have.

But can I tell you that the average parent feels less icky when their kid says, ‘I have been thinking about it, and college just isn’t for me, I want to learn a trade’? I still think a lot of parents get very uncomfortable when they hear that.

“I think sensible people realize that you absolutely need an education in order to succeed, but what we have to try to unwind and unpack is this pernicious belief that the only way to get that is a four-year degree. That simply is not true anymore.”

Fighting to retain art in the trades “If you want to wreck something, the best way to do it is to first minimize and remove the artistry from it,” says Rowe. “Before it was shop class, it was called the industrial arts.”

And shop class, for many, garners about as much respect as a guy in a pair of low-riding Levis fixing the drain under a sink. It’s critical work, and prevents us from devolving into the filth of the middle ages, but everyone cracks jokes and undermines it.

“When people look around and wonder how we completely turned our backs on shop class, well, this is how,” he explains. “You start by taking the art out of the industry, and you are left with vocational education, or Vo-tech, and that just doesn’t sound as aspirational as the industrial arts.

“And then your Vo-tech, becomes ‘Shop.’ And then shop class, once firmly ensconced as a vocational consolation prize, well, at that point, you can walk it out behind the barn and shoot it in the head.”

An epiphany in the sewer “The very first job I did on Dirty Jobs, was actually done a year earlier on a segment called ‘Somebody’s gotta do it’ here in San Francisco when I was impersonating a host on a news show called Evening Magazine,” says Rowe.

“I was quite literally baptized in a river of poo and realized, in the course of trying to host a local news program, that I would be much better suited to work as a guest instead of a host.”

The episode featured Rowe in the sewers of San Francisco as a sewer inspector was behind him, doing his job.

“Every time I tried to host, something else happened. If I opened my mouth, a lateral exploded with the flushed contents of a toilet.

Roaches the size of my thumbs were all over my cameraman and all over me,” he recalls with a laugh that only a proper amount of recovery time can elicit.

“It was actually the rat who crawled up my shoulder that sent me leaping into the air, smashing my head on the ceiling and falling down into the crap. That was the moment I quit.

“So, I turned around and started working with the sewer inspector, a guy named Gene Chruszcz, who was hammering bricks out of a wall, replacing them. I spent the day down there, mixing mortar, interviewing him, laughing, and that was the footage that changed everything.”

M e c h a n i c a l

Anyone who has walked into a well-organized boiler room featuring parallel pipes, perhaps set against a backdrop of diamond plate and sporting custom labels, can appreciate the artistry that still exists in the trades for some, however.

“So many people in the trades, in their own quiet hopes and versions of their identities, see themselves as artists, but society doesn’t anymore,” says Rowe.

“If you take the craft out of the craftsman; if you take the art out of the industrial arts, then you are left with something that probably looks a lot like drudgery, and that’s a tough sell.”

The Way I Heard It

WATCO HI-FLO

Mike grew up as a fan of Paul Harvey’s radio show The Rest of the Story, broadcast out of Chicago for several decades. It was that show that influenced his most recent project, a podcast and book both named The Way I Heard It.

“My favourite stories in the book are the ones that took me back to the woodpile, where Paul Harvey was telling the rest of the story on my dad’s AM radio while we stood out there, splitting wood, day after day after day – our home was heated by a woodstove,” says Rowe.

Let it flow!

“Paul Harvey’s stories were basically mysteries about famous people who you know, that did something that you didn’t know, that, in some way, informed their life or changed their path,” he explains.

“I have always been interested in those stories and I started to write them, really to just amuse myself and to compress time on a plane. Then I started posting them as podcasts. And the podcasts grew.”

When a publisher asked him to compile his favourite ones for a book, he put 35 of them together. Before he submitted the manuscript, he showed it to his mother.

“My mother was like, ‘Look, this is a really lazy book, Michael. What you should do is write a memoir and use these stories to interrupt it. Or, use the stories you’ve written about famous people you’ve never met, and then try and explain why you wrote about them in the first place, in ways that are personal to you,’” he recalls.

“So, the book is either a collection of mysteries about famous people that I’ve never met, interrupted periodically by a memoir, or it is a memoir about my own life, interrupted periodically by true stories of famous people I’ve never met.”

Well into a long run on the New York Times Best Seller list, Rowe claims to now understand, “When in doubt, listen to your mother.”

WHAT IT TAKES TO STRIKE THE RIGHT CHORD Some people marvel at the miracle of the lights going on when they flip a light switch, or their waste disappearing via the flush of a toilet. For others, that magic doesn’t even register.

“It takes a lot of slow dripping to get a person to think differently. You are either impressed or you are not,” says Rowe. “Unfortunately, if you are not impressed, no amount of great PR, no amount of good TV shows, no amount of persuasive magazine writing is going to get that person to change.”

Of course, just because some people refuse to budge doesn’t mean that there is no value in efforts to reframe the view, and some slow drips do turn into rushing torrents. While we all hope to see our messages go viral nowadays, there are historic examples that can show what the right image or right words at the right time can do to change perceptions and behaviours.

The Keep America Beautiful campaign, which featured a weeping Native American at the side of the road,

took direct aim at the littering problem that was prevalent in the ’50s and ’60s.

“In relative terms, it was more pernicious than the global warming conversation,” explains Rowe. “That actually worked. It got people to think differently about littering, and it ultimately got people to change their behaviour.

“The sad truth, really, is that you can’t foster an appreciation for hot and cold running water until the water doesn’t run.”

Mike’s neighbourhood in northern California recently experienced a power outage that lasted for almost five days, and it changed some people’s perspectives.

“I’m surrounded by people who don’t think twice about their infrastructure, or the people who come to their homes and fix things when they break,” he says. “I guarantee you, by the end of the second day, everybody was thinking about it.”

Days three, four and five went beyond thinking. Conversations started to happen.

“Sometimes things have to go splat before people can really, truly understand where their bread is buttered and, in this case, understand how self-defeating and foolish it is to affirmatively marginalize an entire category of our workforce. The category that we really rely upon most.”

Compressor protection devices get intelligent

V

arious local codes and requirements mandate the need to protect refrigeration and air conditioning compressors from over-pressure. Compressors also require motor overload devices to ensure that the electrical “branch” circuit that feeds the compressor will not be permitted to overheat in the event that there is an issue that results in a very high amperage draw.

In some cases, an external overload device is used, wired in series with the compressor motor connection terminals.

However, in most semi-hermetic compressors, a dedicated protection module is installed. These types of protection devices are found in thermally protected compressors and have been used for many years.

More recently, extended protection modules have been developed. In addition to the standard protection, these extended feature modules are more intelligent. They can cycle the head cooling fans, control unloaders, control refrigerant injection, on, control contactor sequencing cing (for example, part-wind starting) ng) and even work k tto o keep the compressor operating rating within it’s intended in nte tend nd ded d envelope. envvel elop lope. e If the operating conditions ns of the compressor are pushed outside the envelope, the module d l will ll notice and d the h compressor will be taken offline. This is a better approach than simply waiting for the motor to overheat or overload.

Of course, the module must be able to sense the suction and discharge pressures along with the discharge temperature in order to be able to offer the extended protection as indicated above.

M e c h a n i c a l

PROVIDING ADDITIONAL LAYERS OF PROTECTION A compressor envelope establishes the minimum and maximum saturated suction temperatures, along with the minimum and maximum saturated discharge temperatures. These limits tend to vary, depending on the compressor type and the refrigerant.

As the protection module senses the suction and discharge pressures, it converts these values to their corresponding saturation temperatures.

These temperatures are then simply compared to the outer saturation temperatures of the envelope.

When the saturation temperatures transcend the outer limits of the operating envelope, the module will output an alarm code for display in the compressor manufacturer’s software or even the equipment manufacturer’s software.

The compressor will be taken offline once it operates outside the envelope. Depending on how far outside the envelope the operating conditions are, the compressor may be shut down immediately, or perhaps after a certain wait period.

As the module monitors the saturation temperatures, it compares the input to the compressor envelope that is stored within the module. Note that this envelope is established once the module is programmed using the compressor manufacturer’s software.

REFRIGERATION A THINKING MACHINE PLAYING BEYOND THE ENVELOPE When the operating conditions fall within the saturation limits, the compressor is operating within its envelope. Conditions that fall anywhere outside the envelope should trigger some form of corrective action.

By dividing the outer perimeter of the envelope into eight regions, the module is able to provide more specific information about the adverse conditions. For example, if the operating point is above the maximum saturated suction temperature (SST) and above the maximum saturated discharge temperature (SDT), then the module will indicate that the compressor is operating in Zone 5.

Intelligent compressor devices can make decisions.

For example, if the actual SST is slightly higher than the limit in the envelope, the module may wait for several seconds to see if the conditions shift back inside the envelope. If this does not happen, the module will take the compressor offline. In that same scenario, if the SST were to increase to an even higher value, the compressor would be taken offline immediately.

Logic such as this allows the compressor to experience transient conditions outside the envelope, but only for a short period of time, and only if the adverse condition is not too far outside the envelope.

But how does the module know when to signal alarms and/or take corrective action?

In this case, the compressor will be operating above maximum load. With conventional protection modules, the motor will be allowed to operate at that high load until it trips the thermal protection device. This is assuming that the high-pressure control was not set to prevent the compressor from shutting down prior to an overload.

Controlling beyond the compressor In addition to monitoring the operating conditions of the compressor, intelligent modules may also be able to provide control of the compressor’s peripheral devices.

For example, liquid injection can be applied when the discharge temperature is too high, unloaders can be cycled according to an analog input signal, compressor starting contactors can be staged as needed, the head cooling fan can be turned on only when needed, and the crankcase can be cycled with compressor operation without the need for a normally closed auxiliary contact on the compressor contactor.

R-22 is best for R-22 equipment.

If you need to change,

One approach is to establish five operating envelopes. One envelope represents the standard operating envelope for the compressor.

Then there are two smaller envelopes that establish the warning and warning reset levels.

Then, two larger envelopes establish the fault and the critical limit.

Arkema has your R-22 Retrofit Solution

In the fault and critical limit envelopes, the fault is followed by a timed shutdown. Therefore, if the condition persists, the compressor will be taken offline after the time delay has expired.

PROVIDING INFORMATION TO A BIGGER SYSTEM As the module monitors the operation of the compressor, it may record the pressures, temperatures, load-steps and other information. This can prove very helpful when diagnosing system problems. Additionally, it may even be possible to share these conditions with a central control system for future use.

Most parallel compressor systems installed in supermarkets already have this ability. However, it is likely that they are not able to protect individual compressors according to their intended operating envelope. In this sense, distributed compressor protection modules can provide important compressor-level information to the main control system.

2020 refrigerant regulations, simplified T

here has been a lot of discussion about what is happening in our ever-shifting landscape of refrigeration regulatory standards in Canada, and unfortunately, most of the discussion ends up eliciting more questions than answers.

Talk to any technician, or even to those of us on the supply side, and you’ll hear, “What is the technical ruling on refrigerant standards”, “What can I use, and when?”, “Why is this happening?” and even “Who is enforcing this?”

A schedule of changes has been put into place, but not all of us have had time to be constantly following what has been put into place – let’s face it, when customers call and we are running with short timeframes to finish projects, it’s no surprise that some of our attention has been elsewhere while these changes were coming into effect.

At the end of the day, however, the premise is to have us using more environmentally friendly refrigerants while reducing our carbon footprint by running more energy-efficient equipment. All good things, but before we can do that, it may be helpful to have a look at the types of equipment that are affected by changes to Global Warming Potential (GWP) limits, and some of the refrigerant options that we will have once these changes take effect (or now, in some cases).

EQUIPMENT AND THE NEW LIMITS

And keep in mind that there is a silver lining to all the changes – in addition to the benefits of saving the planet. Contractors, wholesalers and manufacturers alike will all begin to see new sales opportunities arise from these changes as consumers begin to turn the corner and bring their facilities up to date with the latest and greatest refrigerants.

Here are some of the types of systems that are affected, their GWP limits, and their respective dates of enforcement.

GWP Limit: 1400 (Commercial/Industrial) Date of Delisting: January 1, 2020 GWP Limit: 150 (Residential)

Date of Delisting: January 1, 2025

End Use: Standalone low-temperature refrigeration system: Self-contained refrigeration system with components that are integrated within its structure and that is designed to maintain an internal temperature less than 0°C, but greater than -50°C.

LOOKING TO THE FUTURE So, what refrigerants will be allowed moving through 2020 and beyond?

Environment Canada and Natural Resources Canada want to have a gradual phasedown of all HFC refrigerants, leading up to an 85 per cent reduction by the year 2036.

Despite our ultimate goal being to preserve our environment, this new path we are taking can present some challenges in the mechanical room as not all of our systems can accept new refrigerants when performing a retrofit. It is quite possible to land in a situation where you’re replacing a system and the new refrigerant has different characteristics than the previous gas, which can make the retrofit considerably more complex.

Most Hydrofluorocarbons (HFCs) and Hydrofluoroolefins (HFOs) are blends of gases that have different bubble and dew points, as well as higher glides so, as a result, you may experience a capacity variance. In the event of a capacity de-rate, we often think that we can simply increase the horsepower to compensate, but with a larger system comes higher RLAs, or maximum allowable amps. Depending on the magnitude of the change, you may need to reconsider the electrical requirements.

WHO IS ENFORCING THIS? Environment Canada is responsible for the new regulations, however the government agency has not been clear in saying whether there will be regulatory bodies, such as TSSA in Ontario, who will be deputized to ensure the rules are being adhered to.

The Lowest GWP of ALL Drop-in R22 Replacements.

KEEPING EXISTING SYSTEMS RUNNING It might be helpful to consider that the new refrigerant regulations only apply to new installs and complete system changes. You may continue to use gases that have GWPs higher than the new allowable limit for partial system change, existing system charging and service.

GUEST COLUMN

By Mandy Rennehan

Our industry needs a non-traditional

approach Blue-Collar CEO, Mandy Rennehan, founder of construction and maintenance firm Freshco, travels around North America speaking and consulting with industry companies and incumbents on the significant importance of building an inclusive roster and attracting talent and, more importantly, keeping them in a developmental phase of executing on their projections.

rowing up as I did in Yarmouth, N.S., I can’t help but have grave respect for the blue-collar industry and the hard work that so many people put in during each day to ensure that there was food on the table and a roof overhead.

G

I was a tom-boy at a time when girls didn’t play hockey, and they definitely didn’t become builders or join the trades, but I was fascinated with structure from a young age, and had no idea why.

Somehow, the entrepreneurship gene was in my blood, and by the age of 10, I was brokering fish on my street. Taking the money that I earned, I was able to buy tools, so I started building log cabins in the woods. Now, these were not the five-star projects that my team builds today, but it was a start, and I loved it.

I loved it so much that I didn’t even bother showing up for my high school graduation.

To gain experience in the building industry, I began working for local tradespeople for free. Being female and gay, it was not like there were too many companies opening doors to an apprenticeship for me, but it’s hard to say no when someone is willing to be an extra hand on a job – especially when that person shows up early, asks questions and shows interest in what you do.

Leaving home with nothing but an old hockey bag full of cloths, ambition and a lot of personality, by the time I turned 19, Freshco.ca (not the grocery store) was born as Canada’s first 24/7 retail facilities and construction firm, and we were offering service to some of the biggest names in retail.

company, I became acutely aware of the bluecollar narrative that was affecting the systemic supply and demand issues affecting all industry.

I was the face of diversity before it was a good idea, and inclusive before it became genius in business. Why wouldn’t I be? I didn’t know any different!

At this point, I’m an award-winning entrepreneur and my company, Freshco.ca, is known for its innovation, diversity and fun, but in my world of “we can always be doing better,” I’ve made it a mission to take on the problem facing the trades.

As I went through the ups and downs of trying to build a 114

This is how the Blue-Collar CEO was born.

IT STARTS WITH PERCEPTION Perception is everything. It can crush or create; it can deflate or inspire; it can divide or bring people closer together. And if we are going to create a positive perception of the skilled trades, we need to teach parents about the perception and narrative that is behind the blue-collar industry’s struggles.

The same class system that plagued the United Kingdom for centuries, seems to have sailed the Atlantic, landing in Canada and the United States. The industrial revolution and two World Wars saw the agricultural and working classes leave their homelands to chase the dream of a better life.

This meant the ability to have a house and a car, but best of all, they could get an education for their children.

THE 10-YEAR PLAN When I first started looking at the diversity, or lack of diversity, in the construction trades, the percentage of women in the industry was four per cent – and even less in some of the trades. I’ve made it a goal to push that to 40 per cent in the next decade, and I don’t see any reason why we cannot get there.

Since I started my push to awareness, the number of women in trades has gone to six or seven per cent, so it’s working. The dial is moving.

ARE YOU ATTRACTIVE TO A JOBSEEKER?

They saw that their children could go to grade de school, high school and then go on to attend university or college and gett a profession that could be “respected” by society: teacher, lawyer, doctor, tor, banker.

Their children did not have to have dirty hands nds and work clothes.

Of course, if they did not get good marks in the academic classes, they were streamed into auto mechanics, shop and nd stenography.

These kids graduated high school or left when en they turned 16 and went straight to work or maybe to a community unity college for a technical education. And so, began the real stigma behind the blue-collar perception.

Those same people who shaped our country, y, who worked the manual labour jobs, were looked upon as second class citizens next to their own children who o were the emerging professionals coming out of universities. ersities.

No one should ever feel ashamed for having g dirty hands because they are working hard, doing critical al work, putting in an honest day’s work for an honest est day’s pay, and are providing for their families.

If you have a company and are struggling to find your next generation of talent, it might be a good idea to take a hard look at your company, or even to get a third party to give you an unbiased look.

Is your branding attractive to the new generation?

Do you have the culture and accessibility for all to be welcome?

Let’s face it, traditional ways are not going to work today. The next generation of trades professionals don’t need to look like you, nor should you expect them to. Some might, and that’s okay, too, but if you expect to do things the way they have always been done, we’ll continue to face the same negative connotations about the essential work trades professionals do, and we’ll continue to not have enough people for the work that needs to be done.

The data is already there that supports women and minorities in the industry as game changers. Their skillsets are modern and complement incoming technology and innovation.

If we are going to attract the best and brightest minds to the fantastic careers that the construction trades offers, we have to understand that the newer generation needs to feel purpose from what they do, and most of all, they need to find employers who provide trust, acceptance and an openness to diversity.

Radiant

INNOVATIONS for First Nations homes hen Murdoch and Aura Lee MacPherson of MacPherson Engineering were asked to look into a major problem plaguing Star Blanket Cree Nation homes, they jumped at the chance.

W

Aura Lee had been touring the Saskatchewan First Nation community for a water quality project when local band member Wendell Starblanket mentioned the black mould that was growing in the basement of his home – a common issue that leads to many health and safety issues for the people who live on First Nations land.

As she talked about her company’s radiant heating technology, he asked if it might help with the situation.

On a visit to Starblanket’s home, it was hard not to notice the bag of silica hanging from the basement ceiling with a pail underneath to draw moisture out.

The importance of community

“All the red flags went up. We could see that wasn’t helping to solve the mould and humidity issues,” Aura Lee says. “Wendell asked if we could dry out the walls so the mould wouldn’t grow.”

SUSTAINABLE DEVELOPMENT GOALS

Since the technology works with a forced air heating system, like the one that was already in use at the home, the novel hydronic approach of their system looked to be a potential solution.

Fast Fact The Journal of Environmental Health reports that nearly half of the homes on Canada’s First Nations contain high levels of mould.

Every aspect of the Star Blanket Cree Nation project was planned in keeping with the United Nations 17 Goals of Sustainable Development.

“We worked long and hard ensuring that every decision checked off a sustainable development goal, including making sure that the plumbers and other resources came from the community,” Aura Lee says.

She points to Goal #12: Responsible consumption and production. “We were able to look at existing assets and make them better. That’s one of my favourites.”

Another is Goal #17, partnership. “You can’t tackle a wicked problem like mould when engineers and researchers are sitting in their own gopher holes. It’s only when we work together that we have a chance to solve it.”

PROJECT PROFILE | By Denise Deveau

It takes a village The chance to apply this heating concept on a residential project that would deliver potentially life saving benefits was something that intrigued the MacPherson’s.

They weren’t alone. As word about the pilot project spread, a number of groups jumped on board.

HOW IT WORKS

“The project quickly took hold because a lot of people wanted this problem to be solved,” Aura Lee says. “When we asked people for help, they said yes in the moment. That really took us aback.”

Plumbing and heating product manufacturer Uponor offered its Heliopex radiant tubing, a heating manifold and a number of other system components, and a team of University of Regina research students under the leadership of Amr Henni helped with the design, installation and data research.

At Wendell’s home, a 3” thick closed-cell extruded polystyrene foam product was applied to the walls. This was fitted within a two-by-four border before pipes were added. The installation took three days, with a total cost of $9,000.

What the team learned from that first site was used to refine the process for a second home a little over a year later. For that build, the installing team used a system of four-foot sheets that can be fixed to the wall without the need for modifications, since that only required a two-by-two border to support the drywall.

With that approach, the team reduced the installation time considerably, getting the tubing in the walls in a single day.

“This is the first project in which we combined RadiantLink and Fast Trak for radiant wall heating,” says Nicole Ursu, territory sales manager with Uponor North America. “Because it was faster to install – and with a few mechanical tweaks – we were able to bring the cost down by $3,000.”

Local First Nations contractor Joel Anaquod of Anaquod Plumbing and Heating installed the coil in the furnace ductwork and built and installed the pump control panel with assistance from Uponor. They then connected the PEX piping loops, pressure tested and filled the system, and turned it on.

A RadiantLink coil is installed in the supply air ductwork of the furnace and uses the warm air to heat glycol. The fluid is then pumped through PEX piping that has been applied to the surface of existing basement walls.

As a retrofit, the system doesn’t need concrete to be poured, Murdoch explains.

“Using this method of warming the basement walls is far more effective than using forced warm air directly because you actually heat the thermal mass of the walls, which then radiates heat to the concrete basement floor.

“The best part is, you’re using equipment that is already in the home as the heat source.”

Murdoch is a big fan of the simplicity of the installations.

“This seems to be a simpler, cost-effective way of doing it when you have limited space and resources,” he says. “It’s also a way to use the assets you already have in your home to deliver improved comfort that is healthier.”

Star Blanket Cree Nation is now in the process of presenting the project to the Indigenous Homes Innovation Initiative in the hope that they can secure funding for more installations.

TRICKLE-DOWN BENEFITS Black mould may have been what got the ball rolling, but when the research results were presented by Professor Henni and his students, they discovered other important benefits.

In addition to making the basements healthier, with more consistent heat distribution through the home, the new systems also eliminated the need for electric heaters or fireplaces. Those had been costing residents $500 to $600 a year to run.

Given that a significant cause of death by fire was the result of electric heaters not being used safely, the benefits go far beyond the dollarvalue savings as well.

“The checkmarks were flying off the page,” says Aura Lee. “Nobody was looking at some of these benefits when we started.”

FIND THE FIX

MOVING ZONES TO ADD TO AN ADDITION We’re still crunching numbers and planning the changes to a home where they are looking to build a slab-on-grade e addition to the existing building, to add a master bedroom, m, e en suite bathroom and walk-in closet. The new living space will have in-floor heating that taps into the existing highefficiency mod-con boiler. tion Over the years, this home has gained a second-floor addition and was switched from standard baseboard rads to lower temperature panel rads, lower temperature baseboard rads and an air handler. Ductwork was also added for air conditioning.

Based on these details and the piping schematic, let’s consider the following: 1. If you did a re-piping job, in what order would you put the zones?

3. Based on design conditions, which zone would be the closest to the design temperature number if all zones were calling?

a) 2, 3, 1, 4 b) Three first. If the basement is warm, warm air will rise to the rest of the house. c) 2, 3, 1, 4 but add a mixing valve on 4. d) The order doesn’t matter since the boiler is big enough.

a) Zone 1 b) Zone 2 c) Zone 3 d) Zone 4

2. Let’s do the math. If running on design conditions, what temperature will each zone see if all zones are calling?

4. How would you fix the new zone to work closer to design conditions?

a) 157°F, 152°F, 147°F, 142°F b) 160°F, 152°F, 157°F, 147°F c) With no mixing valves, it should all be 160°F. d) They will all be an average of 151°F.

a) Install a mixing valve set to approximately 101°F (38.3°C). b) Install an electronic outdoor reset mixing valve set to 101°F (38.3°C). c) Set the boiler temperature to 105°F (40.5°C) on the coldest day. d) Move Zone 4 and install it after the other zones, just before returning to the boiler.

Protecting equipment from

electrical surges M

ost consumers think they need surge protection because of proximity lightning that can damage compressor motors and circuit boards within five miles of a lightning strike, however, those strikes only account for 25 per cent of surges.

The other 75 per cent occur when utilities grid-switch power back and forth between suburbs and inner cities daily, or from brownouts, which can occur when an influx of simultaneous air conditioner activations on hot summer days reduces the available voltage and starves appliances of power.

And while whole-home surge protection installed by utilities is a booming business, the unfortunate reality is that “wholehome” is a misnomer because only indoor appliances like washers, refrigerators and dishwashers are protected.

Outdoor appliances like air conditioning or heat pump condensers need their own dedicated protection. To fill this void, the surge protection industry is now targeting condensers with specialty surge protection devices (SPD) that HVAC contractors can sell and install.

Consumers buy millions of dollars of surge protectors for their computers, home theaters and other consumer electronics, so protecting a $5,000 HVAC system with a similar device really should be a no-brainer.

Protecting ductless ess splits Surge protection devices es are particularly uctless mini-split strategic for the rising ductless system market because most of these units exhibit increased over-current ir inverter’s AC susceptibility during their on. to DC voltage conversion.

Surge protection options There are a few different types of SPDs designed for residential and light commercial 120/240V, single-phase split-system condensers.

Most use metal oxide varistors (MOV), which are variable resistors that block voltage surges and re-channel them harmlessly into the ground. Some use thermally-fused varistors (TFMOV). These can also be combined with a gas discharge tube (GDT), a glass-sealed device containing a special gas mixture trapped between two electrodes that conduct electric current after becoming ionized by a voltage spike.

The TFMOV handles the everyday workload of commonly occurring surges generated within the building by millisecond transient over-voltages in addition to supply-side utility voltage load transfers. The GDT handles higher surges and protects against potential MOV leaks.

When looking at SPDs, warranty is a consideration. Besides covering the SPD itself, some warranties also cover HVAC equipment damage if the SPD fails.

Besides warranties, ensure that any SPD you choose for your clients is listed under the UL 1449 Standard for Surge Protective Devices. The UL 1449 Standard addresses protection of the equipment, as well as of the installer. It also confirms that the SPD design has been tested to perform during singleevent surges that can be as much as 60,000 amps, or repetitive surges up to 20,000 amps.

The vulnerability of the variable hese speed compressors in these otection systems makes surge protection e critical for protecting the estment. homeowner’s HVAC investment.

Some SPD models use diagnostic LED lights and alarms that help with troubleshooting and can send alerts when the unit no longer provides protection.

Our continuing commitment to quality products may mean a change in specifications without notice. © 2020 Goodman Manufacturing Company, L.P. Houston, Texas • USA

with Roger Grochmal

Satiating our curiosity, and building more I

regularly ask people around me, “Are you curious?”

Or, in other words, “Are you eager to know or learn something?”

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

In an age where the pace of change is accelerating, I am always amazed at the number of people who think that ignorance is bliss. If this were the case, then everyone would be happy all the time.

Curious (def.): Eager to know or learn something.

I guarantee our customers are curious. Every one of hits the internet before they contact us to buy a new furnace, air conditioner, faucet or whatever it is they need. On that given day, they may be as smart as we are – possibly smarter – about that particular product or problem.

They research not only us and our products, but also our competitors and their products. When we meet them, are we confident that we will be able to answer their questions and come away with an order?

Our employees and our customers all expect us to be on top of our game. Curiosity is the secret.

HOW TO STAY CURRENT See you at the show!

I will be at the CMPX show for all three days.

If you’re curious to chat with me, I can be found working in the Nexstar booth (1630). Please pop over, say hello and start a conversation. It’s why we go, after all.

We have a plethora of options to help us keep in the know.

The online world, of course, provides as much information as we could want – and sometimes more than we can handle.

Trade magazines, like this one, also do an excellent job of keeping us current. And trusted colleagues or associations may send useful articles and information that

helps us keep pace – we all have Facebook friends and other social media contacts that share with us, don’t we?

For me, though, there is nothing better than conversation to stimulate and satisfy my curiosity.

I don’t have the time to meet with all my existing suppliers regularly, let alone competitive suppliers, so, in my experience, the best place to connect with peers for a general update on all that is going on in the HVAC and plumbing industry is at the CMPX show.

The show, for me, is like a financial balance sheet. I can get a snapshot of everything that’s happening or about to happen in the

COMMITMENT ISSUES?

SETTLE DOWN WITH A LIFELONG PARTNER. With all the changes in the market, it sometimes feels like nothing is secure. But Fujitsu is here for you with what youâ&#x20AC;&#x2122;ve come to expect: award-winning support programs, a range of innovative products, and a 100% dedication to contractor success. For a relationship that is built for the long haul, look to the supply channel that starts with Fujitsu.

Ask Roger with Roger Grochmal Cont. cont’d

HOW TO STAY CURRENT industry, all over a three-day period.

That generally sustains me until the next show, two years later.

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

It helps me to understand people better, build personal networks and pave the way for future conversations. I also find a lot of familiar faces in new roles in different companies. I never attend without a pile of business cards – yes, they are still relevant!

CMPX is the right size to connect with a lot of people in a quality way.

BRINGING EVERYONE TOGETHER So, what is it about the CMPX show that makes it so good for the curiously inclined, like myself?

1. It happens every two years.

There is enough change over that time to keep the show interesting and relevant. Company consolidations, acquisitions and new distribution arrangements abound so it’s never the same show twice.

2. It is where all the professionals gather. These are the people who have devoted their careers to the industry, and make it a fulfilling place to work. You’re assured an opportunity to connect with the best.

3. It is contractor focussed, and is a place where we can learn from one another. Every contractor I have ever met has had to persevere though some tough times. That’s why we are all willing to help one another. Having a place to meet and chat is very helpful.

4. Everything I need to know about our industry is represented: new products, new technologies, new smartphone apps and new people are everywhere in the show.

5. All of my current and potential suppliers are there. Many bring senior executives from their respective organizations who enlighten us on what their future plans look like.

You also get a chance to build deeper relationships beyond your territory manager.

People like to do business with people they know and trust, and so getting out there and doing a bit of networking can go a long way.

There’s more than one way to MAKE THE CONNECTION Providing HVAC/R Distributors with a complete line of approved electrical wiring accessories.

Prepare, prepare, prepare

EMBRACING MY TRAITS

Walking into a trade show at first blush can be daunting. Three days can go quickly. To make the most of my time, I always spend some time in advance preparing.

I am one of those really curious people. You will find me in every corner of a trade show, looking for the next thing that will help my business.

And I foster curiosity as well, encouraging as many of our staff as possible to attend events like CMPX. They see things in places I wouldn’t even think to look. The caveat to their attendance is that they must bring back at least one idea that we could implement in the company.

As a result, every show, without fail, brings at least one new product, service or idea to AtlasCare. Some are transformative to our business, while others simply make us a better supplier to our customers.

CMPX saves me a lot of time learning about these things.

One of the first things I do is identify pain points in my business that I would like to address. What would I like to change and make better?

Then I download the show app onto my smartphone and tablet. Everything I want to know is there. I encourage everyone to not only do this but also to set up a profile for themselves. Use the lists of exhibitors, speakers and sponsors as well as the interactive maps. I like to identify the key booths I want to stop in, as well as the people I want to meet.

If there is a special someone on my list, I will get in touch in advance and arrange to meet up with them.

It also helps to bring an open mind to a show.

Inevitably, I stumble on something unexpected. If I’m too focused on my agenda, I might miss these surprises.

These shows are excellent for learning. It’s an incredible value and there is a huge range of subjects to take in.

Keeping Air Moving for Over 60 Years.

And, at CMPX, I never miss the skills competition. Go and check up on what the students are doing and cheer them on. After all, they are the future of our industry – and it doesn’t hurt to identity the top talent while they are young.

ON HVAC

By Tom Cates

Sometimes it is the little things A little while back, I received a call from a family friend who had a problem with the temperature of her newly acquired small town market store/office space.

In the winter, the retail market space and the front entrance were overheating when compared to the office space where the thermostat was located. She also informed me that they had problems in the summer.

The market store had one main heating duct that was visible. It ran down the centre of the store, with three 4” x 10” registers cut directly into the trunk duct.

When I got there, they were all blocked off with duct tape that was falling off, and a window was open to help with the overheating. I also noticed that there were several large commercial freezers being used to store product.

Check the dampers In the building’s mechanical room, there was a volume damper located in the market store trunk duct with the words “winter/summer” written on it. I thought, “Great, if I close this damper, I should be all set.”

Unfortunately, this just created a new set of problems. The first was that the furnace would no longer complete the entire heating cycle without going off on Hi-Limit. I know from HRAI’s RASD training that to decrease the delta T across the heat exchanger, you need to increase the blower airflow.

I opened up the control panel, increased the heating airspeed to high speed and started the heating cycle all over again. Increasing the airflow helped considerably, and the furnace functioned correctly. Now that I had the furnace functioning correctly, I could focus on the temperature problem.

The front entrance was serviced by the office trunk duct and was equipped with a balancing damper, so I got a ladder and partially closed it. I also went into the market store and reinstalled the tape using aluminum foil tape.

Closing the market store damper, taping the registers closed and closing the front entrance damper all helped with the overheating. It also increased the airflow to the three offices, which now satisfied the thermostat faster and made these rooms more comfortable.

Sometimes it can be as easy as closing a damper or covering a register, but you need to look at all aspects of the system to truly improve the comfort and the overall operation of the system.

The office was split into three 12’ x 12’ rooms with ceiling diffusers connected to a second main trunk duct that also serviced the front entrance.

One central return air grille was located in the back office in the h small same room as the thermostat, with fice space door undercuts throughout the office for circulation.

Freezers give off heat When looking at the retail space, it was obvious that the commercial freezers were the main problem. They were giving off a tremendous amount of heat, both in summer and winter, so it was no surprise that the little two-ton A/C unit was never going to meet the needs of this entire building in the cooling months.

HOW HOT IS

FINDING HOT WATER

NOT HOT ENOUGH?

If you have outdoor supply water temperature reset, then there can be times when the water temperature is not hot enough to prevent low supply air, or coil leaving water temperature (freeze) alarms from going off at air supply unit heating coils.

efore we begin, let me ask a question: When does a heating system operate at its maximum capacity?

B

And that will cause a system shutdown, because these sensors require manual resettting. Arghh! Another service call.

Is it when outdoor and indoor temperature design conditions occur?

This condition happens firstly because either the night set-back, and/or the hot water temperature reset is too aggressive in attempts to maximize energy conservation.

Secondly, the return air temperature from the rooms will be that much lower; making the problem worse.

Probably not, because system design calculations are based, or at least should be based, on the building being unoccupied, having no internal equipment gains and at 3:00 a.m. Of course, it might happen if the building has been unused for a while, but then the system should have been permanently set back.

So, how do we avoid this and still minimize energy consumption?

And that is the clue.

If you have night set-back control, then the system works at maximum flow capacity every morning, following reset during the heating season, because all of the room and air system thermostatic control valves will be fully open and the boiler(s) will be seeing full demand.

This is one reason why system capacity is often increased beyond design capacity: to speed up recovery time. Of course, technology can help. Direct Digital Control (DDC) systems can be programmed to “learn” the necessary restart time, based on outdoor conditions. This is something that both electric and pneumatic equipment can’t do.

PRO OTIP Unfortunately, non-empirical additions to capacity exist, such as lack of confidence in the calculations and “rule-of-thumb” assumptions. These must be avoided whenever possible.

Assuming there is only one heating water circulation system, revise the schedule for the automatic controls to temporarily bypass the outdoor reset control, allowing the supply water temperature to go to maximum long before the scheduled start-up time for all supply air systems and until the building is up to indoor design condition.

This will ensure that there is plenty of hot water available for those pesky air supply unit heating coils.

Alternatively, design the system with separately pumped systems, one for the room radiation and any reheat coils, and one for all the air supply unit heating coils, only applying outdoor temperature reset to the room radiation system.

The disadvantage of this alternative arrangement is that it costs more, increases piping heat loss to the air supply system, and would be extremely difficult to do as a retrofit.
