EDITOR’S

DESK

It’s Showtime: On the Floor, and in Print

March/April 2016 Issue Published 6 times per year.

Welcome to our CMPX edition. Once again this year, I am amazed at the level of support from readers and advertisers alike, and I thank both of these vital and valuable groups who allow us to do what we do.

Editor: Adam Freill, ext. 224 adam.freill@mechanicalbusiness.com

This 220-page edition of the magazine is a testament to the power of communication, and of print media in particular.

Associate Editor/Web Editor: Greg Dalgetty, ext. 225 greg.dalgetty@mechanicalbusiness.com National Accounts Manager: Jeff Superle, ext. 221 jeff.superle@mechanicalbusiness.com

Over the past few months it has been disheartening to see closures, layoffs and mergers within the print media community, and I cringe when I hear the oversimplified refrain “print is dead.”

Controller: Liz Mills liz.mills@mechanicalbusiness.com

Print isn’t dead, but any media that fails to deliver on the wants and needs of its audience is.

Art Direction: JJM Graphic Ltd. davem@jjmgraphic.com

The death of any news outlet, be it a website, newsletter or social media site, occurs when the team there is no longer connecting with its audience, when it stops seeking out unique content, and when it fails to deliver information that is vital to its readership. It’s not the medium; it’s the messengers.

Circulation Manager: Shila Naik (905) 272-4175 shila.naik@mechanicalbusiness.com Publisher: Bruce Meacock, ext. 222 bruce.meacock@mechanicalbusiness.com PM:41536047 ISSN 1916-0674 MB (Print) ISSN 1906-0682 MB (Online)

One of the things that I’ve always enjoyed about working as a journalist is having an audience that indulges me enough to allow me to share interesting items that I find – like the Crashed Ice story over on page 86. Here at Mechanical Business, we have a team of like-minded people who enjoy finding and sharing interesting and informative stories, and the more unusual, unique or helpful to our readers, the better.

When a publication, website or social media outlet puts its focus on running press releases, wire copy and articles pooled for use across numerous other outlets, rather than the unique stories that take time, money and dedication to investigate, explore and report, they are taking a step toward their demise, and are doing a disservice to their audience.

Mechan nic ical al Business, we have a defined sector, a niche, within which we seek Here at Mechanical ou ut stories to share w out with you, and rarely will you find our articles in the pages of any o other outlet, and that’s a good thing. Hopefully it’s what keeps yyou coming back.

If you are not headed to the show, I invite i you to check out our Products in Profile section st starting on page 156; it’s like a trade show in print!

Canada Recommends Updates to Efficiency Standards

Kevin Fullan of Wolseley has been elected vice-chairman of MCAC’s associate council executive. He joins chairman Dan Milroy and 1st vice-chairman Mike Miller on the council executive board.

The Government of Canada has proposed several amendments to the Energy Efficiency Act that would increase the performance standards of 20 products.

Nineteen products—including central air conditioners and heat pumps, chillers, commercial refrigeration equipment, and packaged terminal air conditioners and heat pumps—would align with efficiency standards that are already in force or soon to be rolled out in the United States. Efficiency standards for all residential gas-fired storage water heaters would align with U.S. standards for tanks with a rated storage volume of less than 208 L. The amendments would also update the scope, reporting and compliance requirements for gas fireplaces, gas furnaces and large commercial air conditioners and heat pumps.

Housing starts were up slightly in 2015, while building permits remained relatively stable. From January to December, 2015, there were 195,536 housing starts, compared to 189,329 in 2014. The increase was driven largely by Toronto’s condo market. On the building permits front, the value of permits issued in 2015 was $84.8 billion, down marginally from $84.9 billion in 2014 (a decrease of less than 0.1 per cent). This covers permits issued for residential and non-residential buildings across the country.

Profile Marie Li-Ying: A Good Steward

Ask recently elected chair of Refrigerant Management Canada Marie Li-Ying why she became involved with the organization that manages the disposal of refrigerant at the end of its use and she’ll likely explain that getting involved is the bestt way to stay up to date, and to help orchestrate positive change.

“Anyone that I’ve worked with, from the individuals ividuals in the industry, to RMC and the government, everyone is extremely tremely dedicated,” she said during a recent interview from her officee in Mississauga, Ont. “For me, it has been a breath of fresh air. It iss not only the financial aspect of things, we are always conscious of our footprint on the Earth.”

Originally structured to handle the end of lifee of CFCs, RMC added

Q A

Tell us a little about what you do at Honeywell.

Q

How has the regulatory environment surrounding refrigerants changed over the years?

A

We’ve had to go through the Montreal Protocol, the Kyoto Protocol, and other regulations that are being put in place to ensure that those refrigerants in Canada have a cradle-tograve process.

Q A

Why should the work of RMC matter to the trade?

I manage the fluorine business overall for Honeywell. It is a chemical business, at the end of the day, which is a heavily regulated by different agencies. I make sure we are in compliance.

I view RMC as a value-add to anyone doing business in the refrigerant field. How do you know where your product comes from? How do you know how the end of life of the product will be handled? That’s the advantage of buying from a wholesaler who is a member of RMC. You know where the product comes from.

You know how the product is going to be handled when you don’t need it anymore. That’s very important.

the stewardship of HCFCs to its purview a short time ago, and is now looking to include HFCs within its scope.

“It has been a challenge to keep RMC afloat financially. As the volume of CFCs and HCFCs are reduced, so too is the revenue of RMC, and yet the work still has to be done. You still have to take care of the end of life of unwanted CFCs and HCFCs.” RMC recently presented Environment Canada with a draft stewardship plan for halocarbon refrigerants that would affect all importers and manufacturers of these chemicals used in stationary refrigeration and air conditioning. RMC expects the second notice of the plan to be published in Canada Gazette later this year, at which point RMC could develop a process to accept HFCs into its program.

HYDRONICS

B y B o b “ Ho t R o d ” Rohr You can assemble all the ingredients of a delicious dish, but if you don’t follow the recipe you may end up with something inedible. The same applies to hydronic systems.

Consider the components, and their functionality, as you build an efficient and elegant system.

What’s H

ydronic systems are designed to move or transfer energy via a fluid. This could be a hot water heating system, such as radiant or baseboard fin-tube, or any fluid-based HVAC system, regardless of the heat source or emitters, including solar thermal systems, geothermal systems and chilled water systems.

To perform up to expectations, each and every one of these systems needs to have its critical components properly sized, oriented and installed.

UP? Hopefully your air purger!

These components can include the parts that rid the system of dirt, air and, possibly, magnetic particles. Also on the must-have list is the ability to protect the system, so relief valves, low-water cutouts, flow control, temperature regulation and limiting switches all come into view. And the system may need to be zoned for comfort or efficiency. Balancing is important in multiple-zone systems. Temperature mixing may also be desired or required. And the expansion of the fluid in closed-loop piping is yet another part of the system design and installation.

Bob “Hot Rod” Rohr has been a plumbing, radiant heat and solar contractor and installer for 30 years. A longtime columnist and trainer, he is manager of training and education with Caleffi North America. You can reach Hot Rod at bob.rohr@caleffi.com.

HOT ROD’S

NOTEPAD Circulating the fluid requires careful selection of the pump based on the actual load conditions. Domestic hot water recirculation also requires some pump sizing experience.

Get any of the parts, sizes, or even location or orientation wrong and the system won’t likely live up to its billing.

Most manufactured parts and assemblies will have technical and installation sheets available with the product. These are often included in the box. In this day and age, electronic versions of these important documents are a just a few clicks away.

Thankfully, the manufacturing industry has stepped up to offer a wide variety of parts and pieces to handle all these tasks and more.

At times the selection may feel overwhelming, however you just need to think piece by piece.

In some cases, installers become lax in reading the installation directions. Perhaps they feel that one valve or brand is just like any other they have installed. Sadly, installation sheets sometimes become kneepads or paper for lighting pilot lights. continued on page 30

Where questions or concerns do come up, look to the chain of distribution for help. If the supplier of the product doesn’t have an answer to your questions, consult with a local factory rep.

If needed, you can also contact the manufacturer’s technical support.

When seeking this help, have part numbers at the ready, along with digital pictures or videos.

Facetime is another great way to communicate from a jobsite, and is a particularly good way to communicate when a problem is noise related.

Manufacturers are continuously offering product specific training, and lots of training programs are available online. Many suppliers have YouTube channels with archived training, but beware of DIYer produced “advice” videos online. Vet the source of the videos before you buy into the recommendations.

It’s much easier to do a job correctly the first time, especially when it comes to hydronic systems that may require a drain down or taking the system out of operation to correct an installation glitch.

So pick the perfect ingredients, follow the recipe, and place those components properly to provide premier performance.

Match Your Fluid Make sure that the component you have selected is compatible with the fluid in the system, and pay attention to glycol percentages. Temperature and pressure ratings will also be provided with the product, which can help match up the right item for the task.

The quality and condition of the fluid also have a lot to do with the performance and reliability of all the components in the system. Testing the fluid condition every year can prevent premature failure or inadequate performance of the various parts in the system.

Quality Checks A reputable manufacturer will engineer and test a component to assure that it will provide years of trouble-free and efficient service.

Typically, testing is performed to ensure that the component will perform under all the expected operating conditions covered, and that performance expectations are met or exceeded.

In many cases the valve or component will receive thirdparty testing, listing and certification.

The authority having jurisdiction may impose other local requirements for the type or performance of the component, as is often the case with backflow preventers.

Once the part or assembly arrives at the jobsite, it becomes the installer’s responsibility to ensure it is applied and installed properly.

In many cases an inspector will oversee the final job and confirm that, at the least, the system is code-compliant.

A HANDY SCAN A “digital age” way to access information and training is via QR quick response codes. These square-dotin-a-square-grid label codes can be scanned with a smartphone or tablet.

Originally developed in 1994 by the Denso Corporation for tracking automotive components, they are now a part of everyday life. You may see life-sized versions of QR codes on transit buses and billboards, or smaller ones in the ads in this magazine. A number of manufacturers in our industry are including them in their packaging so that technicians have easy access to support documents.

A scan can take you directly to information or a video explaining the installation requirements.

The tech support QR codes do not tend to go into product specs or sales spiels. Instead, they offer just the hard quick facts the installer needs to properly and safely install the component.

These videos are typically short, so there is no reason not to take the time to ensure you have the best plan.

PLUMB AND LEVEL A simple pocket level can go a long way toward ensuring parts and pieces will function properly.

Air separators or vents that have float mechanisms need to be plumb and level to provide proper operation. This ensures the float mechanism inside does not hang up on the inside of the body.

Some products have directional arrows cast, forged or stamped right into them. Safety relief valves may be limited to certain orientations, same for flow switches, fill valves and backflow preventers, so check those instructions, and position the parts right.

Bringing in the boilers Martin Kluck of Byron’s Plumbing

W

hen homeowners on an acreage outside of Calgary were struggling with a lack of hot water and space heating, they turned to Byron’s Plumbing to find a solution.

Their large custom house – a 10-year-old, 13,000-square-foot bungalow with a five-car garage – was being serviced by a 1,500,000 BTUH commercial boiler.

“It was almost like hitting a thumbtack with a sledgehammer. It was too big of a commercial-style boiler that was coming on very fast, hitting its temperature and then turning off,” recalls Martin Kluck, Byron’s hydronic designer. “They were having control board issues, but they were also experiencing overheating in the mechanical room.”

The home features radiant in-floor heating, high-temperature underfloor heating on the main level and extensive snowmelt.

Kluck and his team conducted a heat-loss calculation, and determined that the house would be best served by two 400,000 BTUH fire-tube boilers.

“

If one boiler goes down, the other acts as a backup to ensure space heating is uninterrupted.

2

better than one

Practicality was top of mind when Kluck decided to go with a dual-boiler system. Both boilers provide space heating, while one has a domestic hot water priority. If one boiler goes down, the other acts as a backup to ensure space heating is uninterrupted.

“A lot of the homes out on acreages use a dual-boiler system,” he explains. “A redundant system makes for easier serviceability. If you have an issue with one boiler, you can still maintain space heating with the other.”

The system design was especially useful for the house’s high demand for hot water.

“In this house, there’s a shower in the master en suite that runs at 30 gpm at full capacity,” Kluck says.

“That’s a very high demand, so the dual-boiler system has worked really well for that.”

The system also affords the homeowners considerable peace of mind during Alberta’s blustery winters.

“With the one-boiler system, if you ran into a problem – and you never run into a problem when it’s warm outside – a technician would have to travel out there to assess the situation. But the two boilers installed now stage together, and there’s no interruption to space heating.” continued on page 34

Retrofitting within Reason

K

luck’s team decided to remove the commercial boiler that was in place, along with a 200-gallon buffer tank, and replace it with the two fire-tube boilers and a hydraulic separator. But Kluck was sure to steer clear of any unnecessary replacements.

“On the distribution side of the hydraulic separator, we kept the original system. We didn’t feel the need change to everything,” he says. “You need to consider the economics for the customer. The replacements have to be justified.”

Meeting Expectations

Bryon’s Plumbing also kept the control system that was in place prior to the retrofit.

B

“We weren’t going in there to replace everything,” Kluck explains. “But we also weren’t going in there to replace one 1,500,000 BTUH boiler with another 1,500,000 BTUH boiler.”

“The techs working on this project did a terrific job,” Kluck says.

“They made the job so much easier. Everything went smoothly.

We were happy with the install and happy with the product.”

Kluck ran into a slight challenge with venting, since he was replacing a boiler with a single vent with two new units. But the boilers chosen for the job allowed for side-wall venting, which addressed the issue nicely. The new system also features a remote boiler control, which helps with troubleshooting and system monitoring.

“We can monitor and do adjustments on their system from a tablet or smartphone,” Kluck says. “It’s like we’re in the mechanical room without actually being there.”

Plans are also in place to add a third boiler to the home to service a large indoor pool the homeowners are having built.

yron’s Plumbing received positive feedback from the homeowners on the new boiler system. Showering and domestic hot water needs are now being met, in addition to space heating requirements.

Byron’s Plumbing CEO Wayne McNeely was also thrilled with the results.

“Martin and the team were able to start with a problem, ask the customers what they wanted and needed, do proper heat-loss calculations, figure out the best way of giving the best and most efficient system, and then execute,” McNeely says.

“I love what my team did with this house, and I really loved being able to sit down with the customer and manufacturer to renew their faith in plumbers.

“And to top it off, we were able to install a new monitoring system that helps us look after the home for the customer,” McNeely continues. “It’s just cool. It’s emotional and technical— it’s a hydronic geek’s dream.”

Hand

hygiene ALL IN THE SINK

P

roper sink and faucet design can encourage a more repeatable, consistent handwashing procedure that supports efforts for improved overall hand hygiene.

A

ccording to the U.S.-based Center for Disease Control and Prevention, about one in 25 hospital patients acquires at least one healthcareassociated infection (HAI) every day.

The Public Health Agency of Canada maintains that simple handwashing continues to be the most effective way of preventing HAIs to patients, staff and visitors in all healthcare settings. Even though the clear benefits of handwashing have been proven, the lack of consistent handwashing practices continues to be a significant problem.

A COMPREHENSIVE APPROACH The phrase “hand hygiene” represents a new term in the healthcare vocabulary, replacing the more narrow term “handwashing.”

Hand hygiene is a comprehensive term that refers to handwashing, hand antisepsis and actions taken to maintain healthy hands and fingernails. Hand antisepsis is a process for the removal or destruction of resident and transient microorganisms on the hands using an antiseptic agent, either by rubbing hands with an alcohol-based rub or handwashing with an antiseptic soap. Hand antisepsis has also been referred to as antiseptic handwash, antiseptic hand rubbing, hand decontamination and hand disinfection.

In restrooms with manual faucets, handles are a prime breeding ground for germs.

Touching faucet handles after washing simply re-contaminates hands and reverses much of the good that came from washing in the first place.

While some experts recommend that restroom visitors use a paper towel to turn faucets off, the reality is users are either unaware of this advice, do not care to follow it, or restrooms are not stocked with paper towels.

Therefore, touchless, sensor-operated faucets can contribute to a higher level of handwashing hygiene. The advantages of sensor-operated faucets extend beyond the public restroom to almost any other type of handwashing station, especially in applications requiring the highest levels of cleanliness.

For example, proper handwashing is particularly essential with healthcare workers, who can unwittingly accelerate worker-to-patient and patient to-patient germ transmission.

in Healthcare Settings NEW TECHNOLOGIES

N

ew faucet technology exists that automates handwashing into a simple, timed three-step process. The faucet delivers water and soap in a pre-programmed sequence, including a timed soap scrubbing period that supports CDC and Public Health Canada hand hygiene recommendations.

PROPER TECHNIQUE The “right way” to wash your hands is to wet your hands with clean, running water (warm or cold) and apply soap. Rub them together to make a lather while scrubbing them well, making sure you get the backs of the hands, between the fingers and under the nails. Keep this up for 20 seconds— the CDC recommends singing “Happy Birthday” twice—and then rinse under running water, before drying with a clean towel or air dryer.

Reality shows us that this technique is rarely used.

Michigan State University researchers camped out in public restrooms, and found only five per cent of people properly washed their hands long enough to kill infection-causing germs and bacteria.

Twelve researchers were deployed undercover to public restrooms located across a college town for the study. They observed more than 3,700 people using public restrooms, and found 95 per cent of them were cutting corners. Thirtythree per cent of people didn’t use soap, while 10 per cent skipped handwashing entirely. The average handwashing time was six seconds, far below the CDC’s recommended duration. Men were much worse than women, the researchers observed. Fifteen per cent of men didn’t wash at all, compared to seven per cent of women. When they did wash, 50 per cent of men used soap, compared to 79 per cent of women.

Other supporting technology available includes a visible LED that remains lit while hands are being washed. The LED may also prompt healthcare workers for the amount of time prescribed by established protocols with a countdown feature.

Today’s sensor-operated faucets include a wide range of programming options to not only encourage improved hand hygiene but also hygiene flush options that allow for the faucet to turn on automatically during periods of non-use.

Another area that needs to be addressed in healthcare faucet selection is spray heads, or what a layperson would typically call an “aerator.” An aerator is usually a simple, mesh screen made of metal or plastic that is attached to the end of a faucet with a housing. These spray heads affect the stream of water coming from the tap.

The typical aerator spray head most often used in homes and apartments is the only type that truly mixes air into the water. It produces a larger, whiter aerated stream that is soft to the touch and nonsplashing.

DID YOU KNOW?

Room air can contain bacteria While drawing air from the room and, when mixed with water, around the faucet isn’t a problem in most it can potentially contaminate residential and commercial facilities, it the water. For this reason, can be a concern in hospitals, senior care “laminar flow” spray heads facilities, and medical labs. Room air can are recommended for use in contain bacteria and when mixed with healthcare facilities. water, it can potentially contaminate the water. For this reason, “laminar flow” spray heads are recommended for use in healthcare facilities.

Laminar spray heads provide a single, crystal clear, non-aerated, non-splashing stream that is most useful for high-flow applications or healthcare facilities.

From medical equipment to doorknobs, bed rails and light switches, medical facilities have numerous surfaces that can be contaminated by pathogens. Due to the nature of their use, sinks and faucets are the most critical areas to address in proper plumbing design. Handwashing stations are the last line of defense against the spread of bacteria.

The Public Health Agency of Canada has produced a comprehensive guideline surrounding hand hygiene practices, which is designed to protect Canadians from illness. With such a wide range of product to choose from, faucet selection is a critical component to support these established guidelines and create a healthy environment for all.

oilets account for 30 per cent of the water used in the average household. Given the cost of water and todayâ&#x20AC;&#x2122;s greater emphasis on conservation efforts, some homeowners and business owners might want to reconsider ďŹ&#x201A;ushing clean, drinkable water down the toilet.

Greywater recycling systems recover shower and bath water so it can be repurposed for toilet-ďŹ&#x201A;ushing and irrigation systems. These systems can be installed fairly easily, but it is essential that greywater be isolated from the rest of the plumbing in a house or building to ensure it does not enter the main water lines.

Greywater System

To ensure a successful and safe greywater system installation, here are a few things to keep in mind.

GREYWATER SOURCES

PROPER PIPING

Shower and bath drain water is generally viewed as the best primary source in greywater systems. The water from these drains can be safely routed to a greywater recycling system located in the mechanical room, and then rerouted to the toilets in a house or building.

Since this water is non-potable, it must be run through purple pipe or pipe labelled â&#x20AC;&#x153;non-potableâ&#x20AC;&#x201D;do not drink.â&#x20AC;?

Kitchen water should never be used in these applications. It tends to have a high concentration of oils and particulate matter that can overwhelm a system.

No pipes that handle any form of food waste should be routed to a greywater recycling system.

Insulation:

SHOULD I CARE?

Pipe Insulation? Duct insulation? Equipment insulation? Things that don’t light up, beep, come with touchscreens and remain mostly out of sight? And, no moving parts to wear out? What can be exciting about that?

CONDENSATION CONTROL Summer, and a leisurely afternoon on the patio

Not much really, unless of course you would like to reduce energy consumption, address condensation issues and mould growth, protect people from burns, save water, and maybe even look at how to help reduce the impact of Legionella.

with a cold one in a glass; the water droplets

Perhaps “exciting” needs take on a broader meaning.

on the outside of the glass are comforting.

When it comes to these same water droplets on a pipe, well, that’s not so comforting. That’s

The accumulating water dripping on a floor could ruin flooring materials, create a slip hazard and lay the conditions for mould growth.

A combination of higher humidity and a cold surface means moisture will come out of the air and condense on cold surfaces. We need to prevent this.

A sufficient insulation thickness is required, along with a vapour barrier that is properly sealed. The specific humidity level, ambient temperature and fluid temperature inputs will generate the optimum insulation thickness using an appropriate calculator tool. In addition, the tables in ASHRAE 90.1-2010 and NECB-2015 address minimum insulation thicknesses for a specific set of criteria.

INSULATING FOR PERSONAL PROTECTION According to research done by ASTM International, piping, ducting and equipment with a surface temperature of 40°C (104°F) and higher will cause discomfort when there is skin contact. Pain will be experienced at 44°C (111°F). At 70°C (158°F) there will be “complete transepidermal necrosis (cell death).”

Keep in mind that water boils at 100°C (212°F) and that most hot water systems run at temperatures between 49°C (120°F) and 82°C (180°F).

It becomes imperative that surface temperatures on mechanical equipment where there is the possibility of skin contact be kept at under 40°C (104°F).

Steam lines are another matter and even more critical. The way to maintain a safe surface temperature is with the correct insulation thickness, and once again we look to appropriate calculator tools to determine what that should be. continues on page 44

DOING OUR PART TO CONSERVE ENERGY Energy has a cost to it, regardless of where the price of oil or natural gas sits.

My hydro bill doesn’t ever seem to go down. It goes the other way, and that’s up. This doesn’t make sense to me, but it must to some other people.

As I see it, I have a responsibility to myself to reduce energy consumption if I want to minimize what it costs me. I also have a responsibility to reduce greenhouse gas emissions, simply because everyone will be better off for it.

So, I change lighting, drive a more fuel-efficient vehicle and take public transport, and I buy locally grown food. Every little bit counts, but what is often overlooked is the energy consumed in moving fluids and air in an industrial or commercial building, or in a residence.

Consider that you have to deliver domestic hot water from a boiler to a washroom over a given distance. You want the delivered water temperature to remain as close as As I see possible to the temperature at the boiler, but if the it, I have a responsibility piping carrying the hot water is not insulated, or if it is poorly insulated, the water will lose heat along to myself the way. to reduce

“

energy consumption if I want to reduce, or minimize, what it costs me.

”

This means the boiler will have to work harder to maintain the desired temperature, which results in wasted energy. The harder a boiler has to work, the more natural gas or electricity it will use, and this wasted energy means wasted money for the building owner, and higher greenhouse gas emissions that affect all of us.

SAVE WATER SAVE ENERGY It takes energy to move water and if we waste water, we waste energy. This is referred to as the “Water-Energy Nexus.”

The American Society of Plumbing Engineers (ASPE) has determined that when we allow a hot water faucet to run for more than 30 seconds for the water to come up to temperature, we are wasting water. At 15 seconds we’re fine, and at 20 seconds we’re marginal.

Heat loss along the length of pipe will reduce the initial hot water temperature at the faucet, which means we are more likely to land in the 30 second range waiting for hot water delivery.

Again, insulation can help.

In a recirculating system, the correct insulation thickness will definitely slow heat loss. When water remains stationary until a faucet is turned on, heat loss will occur regardless of the amount of insulation on the pipe. In cases where water is susceptible to freezing, a supplemental heat source is required in the form of electric heat tracing under the insulation.

COMBATTING LEGIONELLA

Reducing the amount of heat along a pipe calls for insulation around the pipe and for the length of the pipe run (there are some exceptions). But, what kind of insulation and how thick should it be?

The American Society of Heating, Refrigeration and Air-conditioning Engineers (ASHRAE) answers this question for most applications in Tables 6.8.3A and 6.8.3B, “Minimum Pipe Insulation Thickness” of ASHRAE 90.1-2010. This is cited in the British Columbia Building Code and the Ontario Building Code.

Similar information is also available in the National Energy Code for Buildings (NECB-2015), Table 5.2.5.3. “Minimum Thickness of Pipe Insulation.” Both Standards also reference minimum thicknesses for duct insulation.

Legionella is nasty, nasty stuff that mostly affects elderly people. The illness can be contracted when someone inhales moist air containing the bacteria.

This can happen when taking a shower.

Legionella bacteria thrive within a range of temperatures, generally between 20°C and 50°C (68°F to 122°F). In colder temperatures it remains dormant, whereas very hot temperatures will kill it. Water in institutions is treated with a chemical to kill the bug. Maintaining a constant hot water temperature in the piping system is also important, and having the optimum thickness of mechanical insulation adds an additional layer of protection.

TAPPING INTO BAS FOR SMALLER BUILDINGS

UV-C for Infection Control lso known as hospital-acquired infections or nosocomial infections, healthcare associated infections (HAIs) are transmitted by a variety of means, including person-to-person, through the injection or insertion of medical devices, airborne contact of open wounds, and by respiration of airborne particles. The most dangerous HAI pathogens are those that have the potential to spread by air.

A

Many of these HAI-causing pathogens, such as Methicillin-resistant Staphylococcus Aureus (MRSA), are now called “superbugs” because they are virtually invincible to standard drug treatments. Favourable indoor environments tend to self-perpetuate these agents, adding to the concern of infection control specialists everywhere.

Engineering controls for infection-control systems in healthcare facilities plays a pivotal role in combatting HAIs. Ultraviolet germicidal irradiation (UV-C) kills all known microorganisms and can be applied to continuously reduce, or in some cases prevent, infectious pathogens from growing on or circulating in hospital spaces and HVAC systems.

Applying Ultraviolet Germicidal Irradiation The installation of UV-C units can be done relatively inexpensively throughout healthcare facilities. Upper-room units can help protect interior spaces; lamps in HVAC ducts and exhaust systems can be used for airstream disinfection; and lamps in air handlers can help disinfect airstreams, coils, air filters, drain pans and other potential reservoirs for microbial growth and proliferation. continues on page 50

There are three primary strategies for applying UV-C systems against infectious agents: upper-air, airstream disinfection and HVAC coil irradiation.

UPPER-AIR UNITS U Upper-air (upperroom) UV-C units can be installed anywhere infectious agents may exist, including in patient rooms, emergency rooms, waiting rooms, isolation rooms and wards, surgery suites, and childcare rooms.

Studies have revealed that by applying upper-air UV-C units, the equivalent of 10 to 16 air changes per hour (ACH) can be accomplished.

These systems work by creating an irradiation zone within the upper region of the space. As convection or mechanical air currents lift airborne infectious agents into the upper air, they are exposed to the UV irradiation where they are killed.

Because people generate many of the infectious airborne pathogens in a hospital, which fall out or plate out onto equipment surfaces and floors, these upper-air systems are very effective at killing in-room, airborne microorganisms.

Another use is to intercept microorganisms from other sources or where cross-contamination pathways exist.

An upper-air UV-C unit kills pathogens circulated into its irradiation zone by drafts, pressure differentials or the movement of people entering, exiting or cleaning a room.

They are also effective against droplet nuclei from coughing, sneezing or the changing of bed linens.

HVAC systems provide an excellent growth area for mould and some bacteria in and around cooling coils, drain pans, plenum walls and filters. Growth of these microbial deposits also leads to coil fouling, which will increase coil pressure drop and reduce airflow and heat exchange efficiency.

This pressure drop can compromise the infection control effectiveness of room-pressurization systems.

Because hospital codes call for high-efficiency filters to be located downstream of the cooling coil, they can also become damp and wet from saturated air. As such, air filters are considered a growth medium for mould and bacteria, and can be an infectious-disease agent reservoir.

Since ASHRAE recommends that UV-C lighting be installed downstream of the cooling coil, a 360-degree UV-C system will simultaneously disinfect both the coil and the filter.

In addition to destroying all microbes in the HVAC coil and the filter, a 360-degree lamp will also kill infectious diseases in the airstream. It is exactly this 24/7 pathogenkilling operation that makes UV-C technology such an ideal supplement to a facility’s overall infection control strategy.

Another benefit of installing UV-C within HVAC units or duct runs is its ability to prevent HVAC generated or recirculating microorganisms from surfaces within a space.

AIRSTREAM DISINFECTION A Airstream disinfection systems employ UV-C lamps to target pathogens from outdoor and return air. Kill ratios of over 99.9 per cent on a first-pass basis have been modelled and, as air is recirculated, concentrations are further reduced by each subsequent pass.

Airstream disinfection is often used in high-risk areas, such as surgical suites, neonatal care centres, and isolation rooms and wards.

Guidance may be found in ASHRAE handbooks, as well as the Ultraviolet Germicidal Irradiation Handbook.

In addition to augmenting existing infection control systems, the 254-nm ultraviolet germicidal wavelength significantly improves HVAC airflow and heat-exchange efficiency levels, which can not only reduce energy use, but also ensure that other infection control practices, such as room-pressurization systems, operate as designed.

Pressurization systems protect against the infiltration and possible cross-contamination of air from one space type to another. When one space is said to be negatively pressured, it assumes that the adjoining spaces are all positively pressurized.

This pressure differential is of great importance in healthcare settings, but very difficult to control. Frequently opened or proppedopen doors are all too common, making corridors a conduit of contaminated air to other spaces. Although operating rooms and other areas are designed to be under positive pressure, this may not be the case when an air handler’s airflow has been compromised.

As air volume drops, so too does the ability of an HVAC system to provide adequate air pressure to protect against cross-contamination. As an air handler’s total resistance increases, there is a corresponding reduction in the air volume output and system pressure, although fan RPM remains constant.

These reductions in a system’s design pressure occur very frequently without much apparent impact.

As performance degrades, so too does the quality, amount and pressurization capability of air supplied to conditioned spaces. Therefore, a higher coil pressure drop will potentially permit the infiltration of contaminated air into protected spaces and out of isolation rooms, negating room-pressurization controls.

In other words, a fouled coil impacts HVAC efficiency and infection control measures.

Indoor Air Quality — Getting to the Source

T

here is no better way to improve indoor air quality than by eliminating the sources of potential pollutants from the indoor environment. Identifying these sources, in most cases, can be done using your eyes and nose, and perhaps some simple inspection tools.

The trained eye and open attitude of a professional mechanical contractor can be useful to both residential and commercial/industrial customers wishing to ensure they or their employees are breathing the healthiest possible air. To assist in identifying sources of pollutants, it is often helpful to think about some of the broad categories of pollutant sources.

Outside vs. Inside Sources First, as you approach a building, think about outside sources versus inside sources.

It has been my experience that clients often want to imagine that any problems must be coming from

something they have little control over, such as their neighbour or the factory down the road.

Properly distancing fresh air intakes from exhaust vents, chimney stacks, standing water, garbage facilities and other potential pollutant sources is a great starting point.

I recall a three-month investigation into an intermittent odour problem in an office building. After occupants logged a host of observations when the odour was present, we identified that the UV degradation of a polymer roof liner—only on bright, sunny days—was creating a chemical smell. The fresh air intake of the packaged rooftop economizer was within 12” of the roof liner and was picking up the smell. Relocating the fresh air intake solved the problem.

Of interest, on the days when the odour was present, the IAQ testing equipment that had been installed did not indicate any issues. The occupants’ noses were more

B u s i n e s s

sensitive than the test equipment. Note that the important clue of the sunny conditions was revealed when occupants took note of outdoor environmental conditions during the investigation. This is one technique for identifying outdoor pollutant sources. Checking the condition of outdoor air intake screens, dampers and filters, or temporarily blocking off or relocating fresh air intakes can also help investigate the potential outdoor sources.

As an example, a residential client was concerned that a nearby highway was responsible for dark “soot” stains on their walls and vinyl windows. However, I found that there was no evidence of the soot material on the fresh air intake filter of their HRV, but lots of it on the exhaust side filter. This helped me convince them that the soot source was from the three large candles they enjoyed burning each night.

Behind Every Successful Contractor There is a Great Partner.

Goodman is mine.

When it came time to find a strategic partner to help take his company to the next level, Mike Martino knew there was only one choice: Goodman. With Goodman on one side and “the best employees in the business” on the other, Martino HVAC became Ontario’s premier HVAC contractor. Service calls were significantly reduced and, along the way, Martino picked up many industry honours including the prestige of being named BILD’s “Trade Contractor of Year” an unprecedented three times.

Martino won’t give you all the secrets to his success, but one he’s happy to share is the importance of a great product partner. As Mike puts it, “Goodman is mine.”

Chemical vs. Biological Sources A second simple way to categorize potential pollutants is to think of chemical pollutant versus biological pollutant sources. Think of biological sources as the byproducts or activities of living things. This could be as simple as the respiration, body odours and carbon dioxide emanating from the workers in a crowded office, the dander from pets in a home or the mycotoxins produced by mould in a basement or ceiling tile.

hygiene and cosmetics used in a person’s bedroom, or the wide range of cleaners and disinfectants used to clean both offices and homes.

A thorough IAQ investigation starts, in essence, with taking an inventory of all possible pollutant sources. Since some people may be affected by a wide range of pollutants, the inventory may include nearly everything we see or come in contact with.

In looking for biological sources, investigators will often focus on moisture issues such as damp surfaces, leaks, cracked and peeling paint, and discoloured or swollen surfaces, since moulds and other fungi need moisture to live.

If yyou are thinking that pretty much everything in a building or home is e a potential pollutant source, then you have the right open mindset to do IAQ investigations. This also means you don’t need a lot of test equipment to identify potential pollutants—a large portion of the identification can be done with your eyes, ears and nose.

Chemical sources could include the ultra-fine particles coming from the printers and photocopiers in that same office, the personal

I mention the nose because in the IAQ world we often say, “If it smells, it stinks.”

One characteristic of good air quality is the absence of odours.

We don’t need lemony fresh or the essence of lavender to make air healthier. Thus any detectable odour in the air is a sign of a potential pollutant. Using test equipment may be helpful later when you begin to assess the relative risk of different pollutants and the appropriate remediation strategies. continues on page 58

It’s a little different in commercial applications, where process or work elements can add to the pollutant source pool. For example, in a welding shop, the fumes from the welder wouldn’t be considered a building-related source, but rather an inherent risk of the work process. Moreover, while it might be possible to encourage occupants to eliminate or change personal hygiene products that are problematic, it wouldn’t be appropriate to tell the welding shop owner that they have to stop welding.

This categorization is also helpful in getting occupants to focus on things they have control over. As mentioned earlier, it has been my experience that people often want to believe the choices they make could never result in an air quality issue. They like to believe that every household cleaner or air freshener, every hygiene product, every carpet or piece of Quiz Answersfurniture they buy is “safe” or even healthy.

continued from page 58

Taking Action Taking action on the pollutant source list should always follow four clear steps, and always in this order:

• Remove any and all pollutant sources that are not essential.

• Isolate or seal pollutant sources that cannot be removed.

• Ventilate all spaces appropriately.

• Filter particulates.

X

The steps start with removing as many personal hygiene products, cleaners, printers and photocopiers as possible, stopping the burning of candles, and fixing the moisture issues in a damp basement.

Sealing strategies would include putting office equipment in an enclosed room, storing any needed cleaners or personal hygiene products in a closed cabinet, isolating the welders in a proper welding enclosure, sealing off-gassing from exposed building materials with an acrylic low-VOC paint sealer, and keeping pets out of bedrooms.

B u s i n e s s

Then provide proper ventilation in offices and homes, and bedrooms especially. Ventilation can often be used effectively in conjunction with sealing strategies. For example, one-tenth the amount of ventilation is needed to control welding fumes if you capture the smoke within a foot of the welder rather than exhausting it from the room as a whole. Similarly, a good bath fan in a bathroom with the door closed is more effective than a whole house ventilator.

The last strategy is filtration. It can be used to target particulates and is best used in conjunction with sealing strategies. It’s really tough to filter a whole house to remove cat dander for a child that might be allergic to the cat.

To be most helpful and cost-effective in your efforts to improve Quiz Answersthe health of the air your customers breathe, be patient and 1 - 35% be thorough by listing all potential pollutants and then use the 2 - False remove, seal,no ventilate and filter strategies to target each one.

3 - Practical, yes; Helpful, Instead of looking for one “smoking gun,” recognize that good air quality is really defined by eliminating as many pollutants as possible from occupants’ breathing zones.

n recent years, manufacturers and wholesalers have been pushing hydraulic separators – also known as low-loss headers – to accomplish primarysecondary piping, but do you need a hydraulic separator for primarysecondary designs? The bottom line is no, you don’t, but they do simplify piping design and can offer several benefits.

The use of closely-spaced tees that are no more than four pipe diameters apart, along with properly sized pipe and a mix of appropriate accessories, will achieve the same results. But there are advantages to the use of hydraulic separators, so let’s take a look at how these units work, along with some of the pros and cons of using these and other pre-made assemblies.

Hydraulic separators simplify piping design & can offer several benefits.

fluid mixes in the small reservoir within the header.

To aid in temperature mixing, separators often have baffles that cause extra turbulence and stir up the fluid as it moves.

Extra, Extra!

A nice aspect of assembled products is that they tend to come with built-in extras, such as air separators, clean-outs, blow-downs, gauges, isolation valves, sensor wells, and other useful things that you might not otherwise add if you had to do it all manually.

The main issue I encounter with lowercost installations that omit these extras is

that when troubleshooting time comes, the client pays and pays and pays because problems become very hard to find, and are sometimes nearly impossible to fix without replacing major components.

Why not just install them in the first place, even if it costs a bit extra up front?

You may not win every job, but you won’t be trying to troubleshoot without good information, either. I will admit that my experience is heavily on the troubleshooting side, but I’ve seen a lot of contractors waste a lot of (unpaid) time by having to go back and try to “tune” a system that isn’t performing quite right – and that’s more difficult without the “extras.” continued on page 66

The prebuilt pitch If you can weld, you can make a low-loss header.

But should you?

Compared to the raw pipe and fittings needed, most of the manufactured hydraulic separators are going to have a higher material cost, so you pay extra for this solution, but what are you getting in return?

The one obvious tradeoff is your time. If you have other jobs waiting, your markup on those jobs is hopefully worth more than paying yourself a few extra hours of labour.

MIXING IT up There are actually a variety of configurations for lowloss headers, based on the type of system you want.

Where the inlets and outlets are located on the supply and system sides affect how much mixing takes place within the header.

For example, you may want to maintain a high system-side temperature. In this case, the best choice might be a separator with the system-side outlet port above the supply-side port, so that very little return-water mixing takes place.

Supply

System

Similarly, the supply-side return port can be moved, based on whether you want the coldest possible return, or for more mixing to take place to moderate the return temperature before water returns to the boiler(s).

Another consideration is space. With boiler rooms rarely being as large as we’d like, sometimes compromises have to be made to allow the installation to be serviced. Pre-made parts can really help with this problem.

Of course, the boiler room may be too tight to assemble a satisfactory solution in the space you have to work in. Then again, it might not be possible to get a pre-assembled part through the door of the mechanical room.

FIG.2

The

In either case, the space might be the determining factor.

One thing we tend to forget about, however, is our human ability to make mistakes. Hydraulic separators are assembled in factory conditions and are tested before being sold, so they tend to be very robust. You might save yourself some frustration by going with ready-made assemblies like the hydraulic separator.

Generally, the more calculations and customization you have to do on each job, the higher the chance an error will occur. The advantage of pre-made parts is that they’ve all been designed to a specific operating range, and instead of figuring out the size of your main lines, take-offs, and such, you might just be able to look up the parameters of a separator, and you’re done.

The other advantage of pre-made products is that they are easily replaceable; that is, you can buy a new one exactly like it, unlike an assembly of soldered pipe.

wow factor

Many of us downplay the wow factor. Why? It’s a boiler room, and we often assume that most clients don’t look down there unless there’s a problem.

But consider this: most hydronic solutions are upscale aspects of a home, and the homeowners like to feel that they bought value.

One very obvious sign of value is a product’s appearance.

I once met a contractor who covers his clients’ boiler room walls with diamond plate sheet metal, and tiles the floors. His high-end clients loved it. And he works exclusively off of referrals. That’s called great marketing.

Making Your Own Low-Loss Header While I don’t generally advise it, if you do make your own header I can offer a few tips.

First, remember that your main pipe needs to be three-times the diameter of your take-offs.

The easiest way to size this pipe for your load is to refer to an existing manufacturer’s technical manuals.

The size and length of the header pipe will vary, based on the flow rate and temperature drop. The spacing of your take-offs also matters, and they should match the application that you’re copying.

Ensure that your primary loop flow is greater than the total flow through all your secondary loops, otherwise you can get unintentional flow reversal in your header.

And don’t forget a top port and vent for air separation, and a bottom port, to purge dirt.

ALL STEAM IS NOT CREATED

EQUAL

WET STEAM? DRY STEAM? WHAT’S THE DIFFERENCE? Take a pound of water (that’s about a pint), and heat it from 32°F to 212°F. That will cost you 180 BTUs, because one BTU will raise one pound of water one degree on Gabriel Fahrenheit’s scale. But you still don’t have steam. That’s just very hot water.

To get the steam magic to happen, to get those water molecules so excited that they leap into space, you need to add an additional 970 BTUs for each pound of water. Do that and the water will instantly expand 1,700 times and charge toward the radiators.

But is that good steam? You know, the sort that will heat the radiators and make the people smile.

Is the steam dry? Or is it wet?

Did you know there were two types?

Back in the day, we were all about the dry stuff.

Steam boilers were tall and had had large steam chests – the hydronic auditoriums where the escaping steam could gather, leaving the liquid water behind.

Those boilers also had wide sections, which allowed the steam to be polite as it rose through the liquid water toward the steam chest. Hey, no shoving allowed!

And since the sections were wide, the exit holes could also be wide. That was great because those wide doorways to the supply pipes kept the steam’s exit velocity down.

If the steam goes too fast it will suck the liquid water out of the boiler and that means wet steam. It’s tough to heat a building with this sloppy stuff because the steam wants to condense in the liquid water it’s dragging along rather than in the radiators. You wind up burning lots of fuel and the building still won’t heat well.

Boiler manufacturers used to test for dry steam, and they wouldn’t give a boiler their seal of approval if it couldn’t produce steam with less than two per cent liquid water.

But then came the movement to make boilers with greater combustion efficiencies. The only way they could do that with steam boilers was to make them smaller. That led to narrower sections, cramped steam chests, choked exit holes, higher steam velocities, and wet steam.

By Definition: wet steam is steam that contains more than 2% liquid water.

So sometime during the ’80s, the manufacturers stopped testing for dry steam, which was good for them because you can’t fail a test you’re not taking. So there!

In place of the dry-steam test they gave us really good nearboiler piping instructions. It then became the installer’s responsibility to pipe the boiler in such a way that the nearboiler piping would separate the liquid water from the steam as it left the boiler.

So pipe that replacement boiler like a professional and it will heat the building. Or cut corners and wrestle with water hammer, uneven heating, high fuel bills, and customers who won’t want to pay you.

It’s good to have a choice, right?

Make the right one. continues on page 70

Dry Humour

IT’S NOT A BIRD. IT’S NOT A PLANE.

You can be laughing all the way to the bank with dry steam, if you go a bit beyond the boiler manufacturer’s instructions. Here are a few tricks of the trade: • Use more risers out of the boiler to the header. If the manufacturer says to use one, use two. You’ll cut the steam’s exit velocity in half and get drier steam.

Manufacturers compete with each other, and if one says their steam boiler will work well with one riser to the header, the competitor will be reluctant to recommend two risers for their boiler, even though we all know that physics rules. Use as many risers as you can and the steam will slow and get dry.

• Increase the size of the header. The larger the header is, the lower the steam velocity will be, and that’s good for both you and your customer. The steam will leave the boiler very quickly – that’s a given these days. A larger-than-required header will slow it down and give the carry-over water a chance to flow back into the boiler rather than up into the system piping.

• Use a drop-header. This is where you come out of your boiler with risers as high as you can before turning through two elbows to drop into your horizontal steam header at a lower level. The rise out of the boiler will leave much of the water behind.

Drop-headers are a Dead Men trick, and they work wonders when it comes to quieting the system and lowering the fuel bills.

70

M e c h a n i c a l

IT’S SUPERHEAT! There’s a third type of steam we call superheated, and no, itt doesn’t d ’t wear a cape.

This is the steam that runs turbines. It’s under very high pressure and it’s hotter than it’s supposed to be. They make that happen by running normal steam through a superheater, where it picks up more heat than it should be holding.

By doing that, it becomes absolutely, positively dry. That makes the turbine very happy. Imagine a very large turbine spinning at, say, 3,600 rpm. Now toss some water in there and see what happens. Whoa!

Superheated steam can cool as it passes through the turbine without turning to water. We don’t use superheated steam for heating because saturated steam, which is always in equilibrium with liquid water at that same temperature, has a higher useful heat content.

Those who work in power plants where there is high-pressure steam will often carry a broom in front of themselves while walking the pipes.

These plants are very noisy and you can’t see high-pressure steam leaks.

You can see the broom’s bristles disappear, though. If the bristles disappear, it means you should stop walking, NOW, or suffer the broom’s fate.

hen plumbers pass on from this mortal coil, they may go to Plumbing Heaven if they’ve had a good, honest career. Plumbing Heaven is basically the equivalent of working maintenance in a new hospital or hotel, or being an inspector or teacher. Better yet, if you’ve been really good, you may spend your time in the hereafter as a rich plumbing owner residing in Scottsdale, Ariz., or somewhere in Florida.

Now if you’ve been bad, you might end up in Plumbing Purgatory, which is like doing service calls for eternity in some trailer park.

And I have had some personal experience in Plumbing Purgatory.

I had a grand total of one and a half years of experience as a residential plumber in Ontario, and one and a half years of experience doing commercial plumbing in Edmonton. I had absolutely zero service experience, so naturally I moved to Calgary and joined a service company.

The first Friday night that I was in Calgary, I was put on call. I was a proud 21-year-old rookie service man, driving a 1976 beat-up Chevy van with bald tires and hardly any stock in the back. I still remember the light blue polyester uniforms our boss made us wear…

It was about 6:00 p.m. when I got my first service call. In 1981 there were no cell phones—just pagers and telephone booths and lots of dimes in pocket change. I still remember being so proud of owning this high-tech black box called a pager.

I felt like a doctor. As a matter of fact, I may have implied as much to the person I was dating at the time.

I was at a church dance when my pager went off. I was dancing with this beautiful blonde, and I explained to her that I had an emergency I had to attend to at the hospital. I ran to the parking lot, jumped in my 1973 Monte Carlo and sped off to get my 1976 Chevy van and quickly change into my polyester uniform.

I quickly phoned the answering service and got the message that it was an emergency water main break at the Red Carpet Trailer Park in southeast Calgary.

I felt like this was my chance to impress my new company, so off I fled into the cold, dark -25°C night.

It must also have a protective concrete pad, a means to protect it from frost heave, as well as a curb stop and a means of draining the part of the pipe located above the frost line when not in use.

efore I delve into any details or specifics of this series I would like to point out a glaring problem that many in this industry of ours don’t understand. Almost all of us, whether in the plumbing, HVAC, electrical or other related trades, all make the same basic mistake: we all tend to abuse suppliers rather than including them in our teams.

What do I mean by this? By leaving the ordering of basic rough-in materials (BRIM) to the last minute and expecting a supplier to get

The opposite can be true, however. They may have the greatest prices, but average personnel that are disorganized and

For a great supplier to complete your orders and be an effective part of your team, you need to give them seven to 10 working days to complete and deliver orders to site, with 10 being the optimum.

Effective materials management all starts with you, the contractor. If you can commit to doing this one aspect alone, ordering four to six weeks ahead, you’ll find that great suppliers will give you all the service and pricing that you desire and deserve.

Finding an Organized Supplier

timeframes. We also explained the challenges we may encounter and asked how they could help and any suggestions they thought would help (there’s usually a compromise between us and the suppliers with this).

We then asked if we could walk through their facility. The reason for this was to see what they normally stocked, and how neat and organized their warehouse is. We asked what they pride themselves in and what they specialize in, along with how they process orders and get them out the door, to the site.

Another important aspect to a visit is meeting key personnel: the shipper, inside sales, quotations staff, the order desk, a materials person.

David Pelletier is a plumber in Manitoba who offers consulting services in pre-construction planning. He can be reached at david@sw5.ca.

The best way to find this out is to visit their facility. This is not an excuse to go out for lunch and a beer. You need to meet the manager and sales rep together, at the branch.

We did this in mid-December with four suppliers for projects I’m working on. We visited one plumbing and three electrical wholesalers. We didn’t book an appointment, we just walked in or called an hour ahead to say we were coming. In most cases I brought my key foreman and we sat down with both the manager and sales rep.

We explained to them how we would be handling BRIM orders on this project, by having a goal to order four to six weeks (20 to 30 working days) ahead of when work crews would require these materials. This should give suppliers seven to 10 working days to bring in any shortages from other branches or their main distribution centre(s) to complete and deliver these orders.

We said up front that we won’t be perfect, but if we can place these orders far enough ahead 75 to 80 per cent of the time, it would give the wholesaler enough time to do their job.

The next step in this discussion was critical. We had to listen to what the rep and manager both said.

Next we explained what our project entailed, size, rough dollars expected to be spent and

Another important aspect to a visit is meeting key personnel: the shipper, inside sales, quotations staff, the order desk, a materials person. It’s also a good idea to pay attention to how each of these key people look and keep their work areas. Are they tidy and friendly? Do they seem to be part of a team?

All this may determine how efficient and organized they will be with your orders, quotes and questions.

After we left one meeting, my foreman said to me, “This supplier doesn’t stock much and it wouldn’t be a good idea to order from them, but they did seem to be a great team that was on the ball.”

So I asked him if he thought our lead time on orders might change his view on what that wholesaler could do, especially since the manager said he was impressed with having seven to 10 days to get materials together and delivered to the site, and that we wanted them to be a big part of our contractor team. He had never heard that before in his 30-plus years in this industry.

I said to my foreman, “If we give them 10 days to get an order together and deliver it to site, do you think they will do that, based on what they said?”

He said yes, so I suggested he send an order to them to add basic stock to an existing project site to see what would happen. Nothing in the order was critical, so there was nothing to lose if they didn’t perform, but it would be a great test to see what they could do.

Words are great, performance and action is even better.

SHELL AND TUBE EVAPORATORS for Refrigerating Liquids

S

hell and tube evaporators have been in use for many years to refrigerate fluids used for a wide range of applications, including comfort cooling and process cooling.

There are differences between flooded and direct en expansion types, however, and many terms used when ese referring to the selection parameters required for these types of heat exchangers, so let’s have a look at somee of the properties of each.

FLOODED Evaporators In a flooded evaporator, the refrigerant evaporates inside the shell and on the outer surfaces of the tube.

The tubing assembly inside the shell is known as the bundle.

exit the top of the shell. This is the reason that flooded shell and tube evaporators are sometimes manufactured with a surge drum above the bundle. Once the droplets enter the surge drum, they tend to fall back into the evaporator.

Liquid enters the shell at the bottom of the vessel.

When there is sufficient liquid in the evaporator, the tubes will be completely submersed.

In designs where a surge drum is not used, an eliminator may also be used to knock out most of these droplets. The velocity of the vapour leaving the surface of the liquid is a low value, often in the range of 100 to 200 feet per minute.

Because the suction connection is located on the top of the evaporator and the liquid inlet is at the bottom, any vapour that forms will quickly rise toward the suction opening and be drawn away by the compressor. This includes any vapour that is formed during evaporation, along with any flash gas that may have formed before entering the shell.

During periods of high load (during start-up and pulldown, for example) the liquid may evaporate rapidly.

When this occurs, it is possible for liquid droplets to

Refrigerants may either be miscible or immiscible with the oil used in the system.

In HFC/HFO and CO2 systems, miscible combinations are generally used. In this case, some oil separates from the refrigerant and forms a layer at the top of the boiling liquid. There is typically at least one skimmer that is used to bleed small amounts of this oil-rich layer back into the circuit to prevent the oil from accumulating in the evaporator.

In flooded ammonia evaporators, the oil and refrigerant are not miscible. These types of systems generally have a drop or drain leg that extends from the bottom of the shell to an oil collection pot. This is used to remove oil from the evaporator.

Since the oil used in these types of systems is denser than the cold ammonia liquid, it settles in the drain leg and oil pot area. This oil must continued on page 84

be periodically drained manually or returned to the main compressor oil circuit via some form of automatic method.

One can easily confirm the accumulation of oil in this area of lower temperature systems because the frost line will move upwards as oil is collected.

When all accumulated oil has been removed, the drain leg and oil collection pot will begin to frost up again.

DX Evaporators In vessels where the refrigerant evaporates inside the tubes and the fluid circulated through the shell, the feed method and evaporator type is referred to as direct-expansion, or DX. The DX arrangement differs from flooded designs because all flash gas formed during the expansion process must pass through the tubing of the evaporator. This flash gas has a significant impact on heat exchange and pressure drop, and must be considered during the design of these types of evaporators.

Another important characteristic of the DX evaporator is the requirement for superheating the refrigerant before it enters the suction return to the compressor.

The evaporator superheat is typically in the range of 8°F to 14°F. This is why DX evaporators must operate at a higher temperature difference between the boiling refrigerant and the fluid temperature. This becomes even more of an issue when the difference between the fluid inlet and outlet temperatures are very low.

In order to achieve sufficient superheating of the refrigerant before it leaves the evaporator, and to ensure maximum heat exchange inside the evaporator, the DX heat exchangers should be configured for counter-flow.

In the illustration showing both flooded and DX types, note that the warmer entering fluid exchanges its heat to the suction vapour that is forming closer to the outlet of the evaporator.

If this evaporator is piped incorrectly, in a parallel flow arrangement, the amount of heat exchange will be considerably less. Also, the evaporating temperature would have to be supressed even further in order to obtain the same amount of superheat.

The cold liquid entering the evaporator tubes has a relatively low vapour fraction and has a much lower heat content. The colder liquid absorbs heat from the fluid that is closer to the leaving end of the bundle. This is another benefit of the counter-flow arrangement.

Fouling Factor When shell and tube evaporators are selected, an assumed fouling factor is considered. Fouling is the build-up of contaminants on the heat exchange surfaces. If a heat exchanger is selected based on a fouling factor of zero, it will have less capacity in the field since there will always be some degree of fouling that takes place; even with properly designed and maintained systems. Fouling factor is typically expressed as ft2·h·ºF/BTU.

Pressure Drop Flooded chillers do not add much pressure drop to the refrigerant circuit. However, in DX evaporators, the pressure drop can be quite significant. Pressure drop through the tubing bundle should typically be less than 5 th psig. A pressure drop of 10 psig is considered high but is used in some applications.

Of course, the main disadvantage of the pressure drop is the reduction of compressor capacity due to lower return gas densities. In order to ensure sufficient oil return to the compressor, a minimum of 15 feet per second is often recommended.

On the fluid side of shell and tube evaporators, pressure drop is usually kept below 10 psi. Low velocities accelerate fouling while high velocities contribute to an increased erosion rate and higher pumping horsepower requirements.

THE FASTEST SPORT ON SKATES Dubbed the world’s fastest sport on skates, Crashed Ice is an ice cross downhill competition where skaters can achieve speeds of more than 50 km/h while hurtling down massive ice tracks filled with drops, hairpin turns and gaps.

The first Crashed Ice event took place in 2001 in Sweden, coming to North America in 2003, and Quebec City, the tour’s most frequent host, in 2006. And the crowds in Quebec can be massive as more than 100,000 spectators line the boards to cheer racers along the obstacle-filled track.

ON A DOWNHILL RIDE

L

uc Despatie wants to see others go downhill, fast, and he’s good with that.

The lengths connect to headers, with lines going in both directions from the header, making most sections of track roughly 120 metres by five metres wide.

Photos: courtesy of Red Bull Crashed Ice and HVAC Rentals

Despatie’s firm, HVAC Rentals, is the ice equipment provider for all North American stops of the Red Bull Crashed Ice tour – that’s the ice cross downhill skating competition that takes a blend of skiing skills, skating skills and a whole lot of adrenaline to win.

86

Now in its 50th year of operation, Despatie’s company was approached to do its first downhill ice surface almost 20 years ago.

“We were approached by an Austrian company that specializes in ice making that was looking for a partner here in Canada,” he explains. “It all started with technology that existed in Europe.”

That technology is a bundle of rubber tubing in a mat that can take the shape of any course imaginable. The mats come in 60-metre lengths and each is around 15 centimetres wide with 10 tubes embedded within. By placing mats side-by-side inside the boards, an ice surface can be created that undulates and turns, which is perfect for an event like an ice cross downhill.

M e c h a n i c a l

In this season’s Quebec City stop, four riders at a time raced down a 460-meter long track starting at the Parliament Building and taking a 65-metre vertical drop to the finish line at Place D’Youville. The USA’s Cameron Naasz took top spot on the men’s side, while Canada’s Myriam Trepanier clinched gold in the women’s event.

“This is a whole plug and play system that is extremely flexible,” says Despatie. “Without the flexibility, you would not be able to do those turns and elevation drops, all that kind of stuff.

“The great thing with this system is that because it is rubber, it is flush on the ground. If we were to use tubing, it wouldn’t stay connected to the ground.” That could cause air pockets to develop, which would not create a strong ice surface.

“You don’t want that air in there because if you make ice, you could end up making a false ice with an air pocket.”

An Ice Guarantee The ice may be artificial, but with Crashed Ice being an outdoor event, Mother Nature can still crash the party, so the refrigeration system needs to be able to perform in some extreme conditions.

“We have to guarantee that there is going to be ice up to 18 or 20 degrees Celsius,” says Despatie.

That translates into a refrigeration system that has a capacity of some 600 tons. Aside from the size, the system is actually not unlike the ice plant that you can find at many rinks across the country.

“In some places we use a glycol mixture, but a lot of places it’ll be brine that circulates at -14°F,” he reports. And while the equipment can vary based on the chiller supplier, the units used for the outdoor events all operate on standard HFC refrigerants.

“None of them are ammonia,” he says. “We wouldn’t be allowed to have those at an event.”

A LESS-THAN SMOOTH RIDE Unlike your local rink, the ice surface for an ice cross event is not expected to be smooth and flat.

“The ice is not to be too smooth, since it would be too fast and too dangerous,” explains Despatie. “It will still be rather smooth, but not as smooth as you would have in an arena’s ice.”

Even with a smooth surface, the course is set up with jumps, risers, camel bumps and other obstacles that test the skaters and keep speeds within a safe range. “They are continuously reinventing themselves trying to get something better and better.”

Hiding the equipment Event organizers not only want a challenging track and great ice, but also a lot of spectators, preferably close to the track. Of course, this can present a challenge for where to locate the chillers.

“The equipment goes where we can put it,” says Despatie. “You don’t want to have these machines along the track. You want to have people along the track.”

In locations like Quebec City and Niagara Falls, space close to the track can be hard to secure, so equipment was selected that can be located up to 100 metres from the track.

“The last one we did in Edmonton, the chillers were all far away from the people and the action.”

AIR AND FLUIDS As with most systems that use fluid to move energy, air is the enemy, and when you are filling up 120-metre lengths of 3/8” piping there’s air everywhere, so purging becomes a priority.

“We do a leak test to make sure the mat doesn’t have a leak, since you are going to be putting in about 5,000 litres of brine in each section,” says Despatie. “Then the first thing to do is get the air out.”

His company uses 2,000 to 4,000 litre tanks to add glycol or brine, and to aid in the removal of the air in the mats. In total, most systems he builds will have anywhere from 25,000 to 36,000 litres of cooling fluid flowing in the tubing under the ice.

According to a recent ComScore Inc. survey, Canadians are the world’s heaviest video consumers. We view an average of 300 videos each month – and they’re not all of rascally kittens, gamers or Netflix Originals.

If you’re an HVAC or plumbing contractor, it won’t take much longer than the drive to work to come up with plenty of great ways to use video in your marketing. Basically, if you’re using an ad, email or direct mail to communicate, there is a pretty good chance that a video can enhance that marketing outreach.

You’ve Shot It. Now What?

Launching a new product? There’s a possible video.

Introducing your sales or technical team so your customers know who is coming to their door? Totally vid-worthy.

Using customer testimonials and footage of installation before-and-afters? Yep, there’s another.

Once your masterpiece is up on YouTube, you need to help it reach the world. Consider how you are going to promote it so that you can maximize exposure.

Give it prominence on your website. When uploading it to YouTube, include a transcription of the audio and any vital visual cues that appear in the video.

This, in addition to your tags, can be searched by viewers to help more people find your content.

And, of course, blast out a link using your email list and social media channels so that your core target audience knows to check it out.

Ten Tips from Video Pros

1

Get a decent camera.

There is no doubt you e can do this yourself with a little e practice, however, smartphone cameras aren’t ideal; they’re grainy and the results are often shaky. A good video camera will cost less than $500 and deliver professional quality footage.

2

Light it right. Video is best in a well-lit, high contrast environment where extra lighting is brought in from the sides. Don’t rely on top-down fluorescents. A couple of directional floor lamps will do the trick without busting the budget.

3

Don’t forget the sound quality. People want to watch your videos because they want to hear you speak. Make sure you have a camera that has a good microphone so that your potential clients can clearly hear you without any distracting ambient noise. If you want to add music under the spoken word, ensure it’s not a distraction.

4

Establish one simple goal for each video. A common mistake with videos is trying to say too much. Pick one topic and cover it succinctly in 60 to 90 seconds. Working from a well-written script will help.

5

Create a storyboard. You don’t need to be an artist to create a storyboard, or cue-by-cue plan for the video. This high level framework will keep you on task as filming ensues.

6

Be practiced, but not rehearsed.

On-camera folks don’t need to sound like James Earl Jones or look like Diane Sawyer – you just need to be relaxed and confident.

Shoot a few warm-ups before expecting a perfect take. Be yourself. Show some personality. And don’t be a robot: you should be comfortable with the content, but don’t memorize the script.

7

Close with a call to action. As with any other marketing, we need to tell people what to do. Try to wrap your video by reiterating the required action – verbally and, ideally, with text on the screen.

8

Keep animation in check. It’s pretty easy these days to include some animated text in your video. Don’t overdo it though. Your video should be all about conveying a message instead of visually impressing viewers. If you’re animating, ensure that it is implemented at a comfortable pace for the audience.

9

Test it. We get awfully close to these things. Before finalizing, be sure to have someone who hasn’t seen the script watch the video. Is the pacing right? Does it make sense?

Leverage local talent. Not comfortable shooting it yourself?

Look to your local students. In some high schools, programs exist that work with local businesses to give students real-world experience. There is so much young talent that would kill to work on a stipend or internship on an actual corporate project. It is a win-win.

PIPE SIZING

B y L an ce M acN evin

sizing PIPES FOR FLOW RATES

W

hat information do the designers of hydronic heating/cooling, snow and ice melting, plumbing, and geothermal systems need to know to make good decisions for sizing pipes? They know that the pipe must transport a specific fluid at the required flow rate and temperature over a certain length, but what else?

The adversary is friction. Friction requires the use of circulating pumps to overpower it, and circulators use electricity, an important operating cost.

Selecting larger pipes reduces friction, but increases costs associated with bigger fittings, hangers, transportation, etc. How do we decide the right pipe size?

When sizing pipes, we need to do some important calculations to find the optimum size, the balance of cost, pumping and thermal efficiency, and longevity.

Up to now, designers relied on manufacturers’ tables or graphs to calculate factors like velocities and friction loss, but there is always the chance of miscalculating the total loss for the exact length of pipe involved. Also, if we are using an antifreeze mixture for hydronics, that changes the frictional loss.

Designers can do manual calculations when armed with intimate knowledge of the pipe’s exact inside diameter and smoothness, the specific characteristics of the exact fluid being used (e.g. viscosity, density), and the fluid temperature.

There are many possible antifreeze mixtures, so that’s a lot of data, and another chance to miscalculate.

To help streamline the pipe sizing process for plastic pipes, designers can now go to www.plasticpipecalculator.com for new online software that does these calculations quickly.

THE PLASTIC PRESSURE PIPE DESIGN CALCULATOR Developed by the Plastic Pipe Institute’s Building and Construction Division (BCD), the Plastic Pressure Pipe Design Calculator is a free tool that allows users to calculate such values as pressure or head loss for PEX, PE-RT and CPVC piping systems.

PPI members collaborated to provide this calculator by reviewing established formulas and manufacturers’ design factors.

The tool can also calculate thermal expansion/ contraction and pipe weight and volume. It can even help designers specify the lengths of expansion arms or loops, especially important for larger diameter piping systems.

Programmed by Avenir, a well-known developer of software for the mechanical and plumbing industry, the calculator gives users access to significant calculating power based on information from ASTM and CSA standards for the three most commonly used plumbing and heating pipe materials. The tool displays in either inch-pound (US) or metric (SI) units of measure.

CHECK THE VELOCITY Steel or copper pipes have maximum velocities for hot water, typically 4 and 5 fps, respectively. These limits were agreed to long ago to prevent erosion corrosion, noise and vibration. Excessive velocity will actually wear away the inside of metal piping, leaving horseshoe-shaped deformation inside where material is washed away. Eventually, erosion corrosion thins the pipe walls, often near fittings or when there is extra turbulence.

Plastic pipes, like PEX, PE-RT and CPVC, have an inherent resistance to erosion corrosion, vibration and noise, so higher velocities can be tolerated by the pipes without harm, but friction is still a factor and must be accommodated with a correctly-sized circulator.

PIPE SIZING

continues from page 92

USING THE

CALCULATOR Let’s use a hydronic distribution example, where we are sizing a pipe to carry 180°F fluid from a boiler to a fan coil that requires 30,000 BTUH. The owner wants to use 30 per cent PP glycol to prevent a frozen system in case of an extended power outage.

The universal hydronic flow rate formula tells the designer that the fan coil needs at least 3.3 GPM to maintain a temperature drop of 20°F or less (about 10 per cent higher flow rate than if we were using straight water). The fan coil is 80 ft. from the boiler.

We’ll start the design using 1” CTS PEX tubing, and see if this is a good size.

We can also include 8 couplings and 4 elbows in the pipeline, taking the head loss through the fittings from the manufacturer’s data, expressed as equivalent pipe length. This shows that adding these fittings is equivalent to adding 16 ft. of pipe length.

WATCHING THE MIDDLE For pipes intended to transfer heat through the wall, like pipes used in geothermal, radiant heating/cooling, or snow and ice melting systems, there is another concern. If those pipes are oversized and the flow rate is too slow, laminar flow can develop.

Laminar flow sounds great, but the potential problem is that slow-moving fluid can cling to the inside of the pipe wall in a so-called boundary layer, effectively insulating the faster fluid in the middle of the pipe and reducing heat transfer through the pipe wall.

It’s like the BTUs are trapped inside the pipe and can’t get to the wall to escape.

Imagine a busy five-lane highway with off-ramps on the left and right; the middle lane would move the fastest, but it would be difficult to merge from the middle lane to get off the highway.

Having all traffic at the same speed facilitates merging, just as having turbulent flow within a pipe helps heat transfer through the pipe wall. But how do we calculate this?

When we click

CALCULATE we get our answer: Based on the calculator, using 1” PEX for this pipe will result in a head loss of just 1.9 ft. per 80 ft. of pipe length, a total of 3.8 ft. The velocity is just 1.8 ft/sec, not a concern. The flow regime is turbulent, but that’s not a concern for a heat distribution pipe. The pipes will be insulated.

We can also check results for 3/4” or 1-1/4” PEX, or change everything to metric units with the click of a button.

If needed, we can click print, or email this data directly to the customer who might be making this decision on the job. It works great on mobile devices, so they can do this in the field.

Going Underground at the

Montreal Biodome

Olivier Matte

E

very year, over one million visitors flock to the Montreal Biodome to get a look at more than 200 animal species living in four distinct habitats. The 377,000-square-foot facility features a tropical rainforest, a subpolar region and ecosystems replicating the Gulf of St. Lawrence and a Laurentian maple forest. Maintaining the proper

environmental conditions for the wildlife and fauna at the Biodome is of the utmost importance. To address all of the habitats’ heating and cooling needs, Montreal-based Ecosystem installed an extensive heat recovery network coupled with an open-loop geothermal system. The project has earned numerous distinctions, picking up the Association of Energy Engineers’ International Project of the Year award in 2015 and ASHRAE’s Technology Award in 2013.

We spoke to Olivier Matte, Ecosystem’s training and awareness coordinator, to learn more about how this system works and the challenges Ecosystem faced during its installation.

An Ambitious Installation

“Heat recovery is our number one source of energy,” Matte explains. “We recover all the energy from the other ecosystems and use it in the rainforest. The rainforest is kind of like the back of a refrigerator, where all the recovered heat gets dissipated.” A 250-ton heat pump is dedicated solely to cooling

Ecosystem installed four heat pumps totalling 1,600 tons in cooling capacity. The heat pumps are connected to two distinct and newly designed networks serving the purpose of heat recovery and hot water heating. These networks supply each habitat as well as the administration area, allowing either cooling or heating. They are designed to optimize energy recovery, transferring excess heat from habitats in cooling modes to the rainforest habitat, which is always in heating mode.

the subpolar habitat, where the water/glycol solution must be chilled to -6°C to meet the ecosystem’s requirements. The other habitats require a 6°C solution in cooling mode, which is generated by the three remaining heat pumps, all of which have 450-ton cooling capacities. These heat pumps operate at a more efficient COP, while the subpolar heat pump does the heavier lifting.

Exceeding Expectations Aside from the open-loop geothermal system, Ecosystem also installed high-efficiency lighting as well as an enhanced pump and water filtration system. Since the project was completed, the Montreal Biodome has had a 55 per cent reduction in energy consumption. It has also reduced greenhouse gas emissions by 80 per cent—or 1,600 metric tons—per year.

What’s more, the system is performing to a higher standard than was contractually guaranteed.

“We had quite ambitious targets for annual savings, and we exceeded them by 19 per cent,” Matte says.

Additional equipment control strategies were also implemented for optimum electricity peak demand management.

“During the summertime, the Biodome cools the underground lake at night,” Matte explains. “The heat pumps are used to lower the temperature and this avoids peaking with electricity demand during the daytime. During

Photo: Ecosystem

When energy recovery exceeds the requirements of the rainforest, excess heat is stored in a subterranean lake that sits 10 metres below the surface of the Biodome.

When the heat recovery alone is not enough to warm a habitat, the open-loop geothermal system kicks in, drawing on energy stored in the lake. The temperature of the water in the lake is typically 22°C at the end of the summer, and 12°C at the end of the winter.

Full Steam…Behind Prior to Ecosystem’s installation, the Montreal Biodome was serviced by an old steam-heating system.

“They were buying chilled water and steam from the Olympic stadium, which is right next door,” Matte explains. “For the polar world, which needs much colder water, they were relying on very old compressors that were on site at the Biodome to further cool the chilled water bought from the Olympic stadium.”

Installing a new system posed some unique challenges. First and foremost, a complete system shutdown was out of the questions, since all the animals and plant life in the Biodome require specific climatic conditions to survive. “Throughout the duration of the project, we had to consider the living species,” Matte says.

But that was only one of the challenges. The mechanical room itself proved difficult to access, which necessitated a creative approach to installing some of the equipment required for the job.

“We had to haul the heat pumps over the electrical room,” Matte recalls.

“And we had to create an internal bridge with rails to haul the chillers over the mechanical room. There were only a couple inches of clearance on each side of the chillers.”

The heat pumps, all of which use R-134a refrigerant, warm water to 35°C in heating mode. For the heat recovery system, six steam coils were converted to hot water coils in the various ventilation systems. Previously existing cooling coils are now also used for heating in the winter months.

the winter, it’s the exact opposite. The Biodome starts cooling the pond in the morning.

With 3,000,000 liters to cool, only a 0.5°C temperature difference means a lot of extra recovered energy to heat the other spaces.”

RETOOLING RATINGS for Energy Optimization

H

VAC/R systems are among the biggest users of electricity in commercial buildings. As such, the building industry, government entities and utilities are taking on a new mandate to minimize energy footprints and are promoting the need to optimize systems and conserve resources through recommissioning and continual commissioning.

To do this effectively we need an accurate way to analyze these systems. To-date, however, field measurement of performance of HVAC/R systems has been uncommon and limited. These systems were often considered too complex to evaluate, or the price of these evaluations was viewed as simply too costly.

As such, the terms COP, EER and kW/ton were commonly associated with operational efficiency. Although these are valuable guidelines, they are not true indicators of overall system efficiency.

Over the past few years, a number of organizations in Europe have introduced an innovative solution that benchmarks the efficiency of an HVAC/R system against its ideal Carnot process, independent of losses and external operating conditions. This solution is known as the System Efficiency Index (SEI).

With the introduction of this cost-effective performance analyzing method, there is a considerable opportunity for contractors and consultants to overcome this challenge, and to improve the performance of HVAC/R systems.

A benchmarking tool

When assessing HVAC/R equipment, manufacturers and testing organizations conduct tests under controlled conditions. This makes it straightforward to evaluate different systems and efficiency against design specifications.

When operating in the real world, however, these systems are no longer in environments that can be controlled, so they end up operating under different, and varying, conditions. As a result, it becomes more difficult to use such performance

M e c h a n i c a l

B u s i n e s s

System Efficiency Index (SEI) is not dependent on operating conditions such as temperatures and flow, however. This makes it an ideal method to evaluate true efficiency, since it is based on how close the system is operating to what would be defined as an ideal process without any losses (i.e. Carnot process).

There are three things that need to be considered for SEI to make values comparable:

1. System Type 2. System Boundaries 3. Reference Temperatures The system boundaries and operating conditions have to be defined based on the type of system. With defined reference temperatures the Carnot COP (loss-free) can be calculated, and the SEI can be defined as the measured COP divided by the Carnot COP for the same reference temperature.

Since SEI is a ratio, the system SEI will not change from day-today as operating conditions change.

System Efficiency Index:

102

parameters as COP, EER, SEER and IEER since they are highly reliant on ambient and operational conditions. For the same reason it is very difficult to evaluate true efficiency.

0 4 . 1 6

A change in the performance of one or more of the subsystems (sub-efficiencies) will change the overall SEI, however.

This makes SEI a very powerful tool for monitoring and maintaining optimum energy efficiency.

Furthermore, incorporating SEI into a Continuous Energy Efficiency (CEE) monitoring program will also provide the ability for building operators to receive alerts of pending failures.

Reference Temperatures Carnot COP is calculated from temperatures that are defined as reference temperatures.

These temperatures are used for the secondary fluids (air or water) that are subject to cooling and heating during the thermodynamic process. Defining these values allows for the evaluation of evaporator and condenser performance, which is not the case with the traditional use of COP. This allows for the analysis of all system components and provides a better representation of system efficiency.

SEI (cooling) =

DIDYOUKNOW? SEI is a tool used to describe the performance of an HVAC/R system, independent of operating conditions.

SEI can be divided in sub-efficiencies, allowing identified losses to be allocated to such components of the system as the compressor, condenser, evaporator and refrigeration cycle auxiliary loads.

Work on defining the most practical and useful reference temperatures and system boundaries for direct expansion and complex systems, such as cascade and transcritical CO2 systems, is currently being refined.

The measured COP divided by the ideal (Carnot COP) produces the calculated SEI to quickly pinpoint actual system performance and identify where and when losses are occurring in each step of the process. This allows sub-efficiencies to be established.

The possibility to identify and benchmark these weak points contributes to making SEI a powerful tool for fault detection and ongoing system monitoring.

The most noted subefficiencies for most applications are:

Cycle efficiency – The losses caused by the refrigerant process deviation from an ideal cycle with a 100 per cent efficient compressor.

Compressor efficiency – The losses in the compressor, which includes all losses in the compressor and motor.

Condenser efficiency – The difference of the measured COP compared to that of the same system with an ideal condenser (infinite surface).

Evaporator efficiency – The difference of the measured COP compared to that of the same system with an ideal evaporator (infinite surface).

GOING BEYOND BUSINESS AS USUAL It is often believed that if the specified temperatures are being delivered and no alarms are generated then the operation of a building’s HVAC/R systems is good, and no actions or modifications are needed.

This “business as usual” approach results in most systems having much higher energy consumption than is necessary. Often a lack of understanding of the importance of tuning all the components in a system to the load and climate conditions of that particular system is what leads to this less-efficient operation.

To change the business as usual approach, building owners, system operators and energy managers need to change their perspective from a traditional initial or first cost to a total cost of ownership perspective, inclusive of lifecycle costs such as energy efficiency as well as standard maintenance.

or David Nagami, finding a home in the mechanical trades was a bit of a happy accident.

When he was in Grade 12, Nagami completed a co-op placement with a plumbing and heating company in Toronto. Not long after that, he found himself in need of a job. As it happened, his neighbour ran an HVAC business— and he was in need of some hired help.

“He owned his own business doing subcontracting work,” Nagami recalls. “I was looking for a job at the time, and he happened to need help. I started working in the field, and I really enjoyed the work.”

Nagami is now an apprentice at Cool Check Air Conditioning, which is celebrating 25 years in business, and he hasn’t looked back since taking his first leap into the trades.“I don’t like sitting still—I couldn’t work at a desk,” he says. “It’s always a challenge when you get a service call. You can’t picture what it’s going to be. It’s always something new.”

What’s your service area?

The Greater Toronto Area.

What’s the most recent project you’ve worked on?

An elevator room cooling system at the University of Toronto’s downtown campus.

What’s your favourite part of the job?

There’s something new every day and you’re always moving.

How much time do you spend on the road each day?

That varies depending on the job, but on average I’d say a couple hours per day. A lot of the time spent behind the wheel is sitting in traffic downtown. You could spend a quarter of your day sitting in the truck.

Do you have a favourite place to be dispatched to?

The Toronto Congress Centre. It’s close to my house and the guys there are great.

I’ve got to know the staff pretty well. A friend of mine from the company and I share the account.

What’s the most memorable project you’ve worked on?

A big cooling system we installed at a data centre at a security company. It was the first time I’d been exposed to something like that, because I was originally working on the residential side of things. It kind of blew my mind seeing a piece of equipment that was the size of two or three trucks put together.

What’s the strangest thing you’ve ever seen on the job?

One time at Berkley Castle in downtown Toronto, what looked like a small fox got electrocuted and ended up fused to the copper tubing inside an air conditioning unit. When I opened it up to do some pressure-washing, I had to pry the animal out with a hockey stick. It was completely stuck to the piping. I really had to work at it to get it out.

Favourite tool in your toolbox: My digital multimeter. That gets me through my day most of the time.

Favourite musical artist: I have many favourites, but the top two would be Pink Floyd and Wu Tang Clan.

Favourite concert: A Blink 182 concert at the Molson Amphitheatre I went to when I was in Grade 8.

Favourite car: BMW M5 Favourite movie: Moneyball Favourite TV show: Breaking Bad Favourite sport: Baseball Favourite food: Steak Favourite beverage: Stella Artois What’s one place you would love to go?

Miami for Spring Break.

If you were prime minister for one day, what would you do?

I would lower taxes.

Biggest pet peeve: Drivers who don’t use their turn signals.

Do you have a personal motto?

You’re only young once. Live your life as fully as you can.

PREVENTING SLIPS AND FALLS S

lips and falls are major business for hospitals in Canada. Ontario on its own averages more than 21,000 emergency room trips every year from people who have lost their footing on snow and ice. Those numbers are just for falls that were severe enough to warrant seeking medical attention.

Anyone who spends time on rooftops between late-October and mid-April can likely attest to encountering their fair share of slips – hopefully minor, but sometimes not. It is not uncommon to feel one’s boots slide on ice that’s formed in areas with imperfect drainage, or on accumulated snow while working on equipment or repairing pipes on top of a building.

For the past three years, apparel and footwear retailer Mark’s has been working with the Toronto Rehabilitation Institute to better understand the challenges of a Canadian winter with an aim to improve safety when walking on ice while wearing either casual or industrial footwear.

“It is a big deal, both in the construction industry and for people in general,” says lead researcher Geoff Fernie of the Toronto Rehabilitation Institute. “We built a facility to test for all kinds of safety, including winter.”

World-renowned as the foremost research centre for balance, mobility and falls, the Toronto Rehabilitation Institute built a winter simulator to put boots through their paces. Dubbed the “Winterlab,” Fernie and his team have been using it to learn more about footwear and its performance on ice and snow.

Mechanical Business editor Adam Freill tests the gripping power of a pair of boots in the Toronto Rehabilitation Institute’s Winterlab.

“When you look at a pair of boots, you can’t tell their ability to grip by looking at them,” he says. “We decided to come up with a reliable test measurement.”

As a result of this type of research, footwear manufacturers are following some of the same footsteps where tire manufacturers have tread, trying out new rubber compounds and even experimenting with such innovative additives as crushed walnut shells and pulverized glass.

The test is the ability to comfortably walk up a slope. Starting from a level plane, participants walk on an icy surface. With each subsequent pass, the angle of the floor is increased to determine the point where slipping occurs for the footwear being tested.

“If I think about the boots we would have sent to Geoff 10 years ago versus what we are testing today, so much has changed,” says Iain Summers, vice-president of industrial and footwear at Mark’s.

“We test for three surfaces: ice that is dry, ice that is wet and snowsprinkled ice,” says Fernie. “We want boots that can go up the steepest angle and work on all three surfaces.”

“We are going to make a difference for so many people,” adds Fernie. continues on page 110

Seeking a Way to Compare With no real way to compare one boot’s gripping ability to another in a store, the research team at the Toronto Rehabilitation Institute is hoping that their work will lead to a set of symbols or ratings similar to those found in the tire industry to help guide consumers.

“We are working with Mark’s to develop standard measurements, and to stimulate the industry to want to do better,” explains Fernie. “In some provinces, snow tires are mandatory, but we do nothing on boots.”

While symbols on boxes might help with an initial purchase, research is also being conducted on ways to incorporate wear indicators on the soles of boots to help indicate the amount of grip remaining, to help keep wearers safe long after they have left the store.

DIDYOUKNOW? Although a little bit of water can reduce friction on ice, researchers have found that the surface that causes the most difficulty for grip is ice with a light dusting of snow.

The Winterlab is a 6 metre by 6 metre ice box.

Winter, 365 Days a Year The Winterlab at the Toronto Rehabilitation Institute is a six-metre by sixmetre simulator that is able to reproduce Canadian winter conditions in a controlled and repeatable way.

The floor surface uses embedded tubes with refrigerant running through them to create an ice surface that can be made cold and wet or colder and dry, with the option to add falling snow, snow on the ground, and even heavy gusts of wind.

The lab has a flight-simulator-style motion base that can tilt, move or shake to simulate ramps, slips and trips. An intelligent robotic harness system keeps research participants safe and comfortable throughout the testing.

IT’S NOT JUST FOOTWEAR Iain Summers, vice-president of industrial and footwear at Mark’s, views work boots as more than simply footwear.

“Work boots are tools,” he says, explaining that a professional tradesperson has much different requirements and expectations from their footwear. “The amount of hours that someone wears their boots…it is very different from a casual consumer.”

The challenge is finding rubber compounds that provide safe gripping ability, but that are durable enough to stand up to the rigors of a jobsite.

“We need to find a balance. Working guys don’t want their boots to wear out,” he explains. “We want to give them work boots that will last six months to a year. If it is a boot that’s lasting six months, you get a full winter out of it.”

WATER,

THE LIFEBLOOD OF EVERYTHING

CLEAN WATER

protects A ROLLING INVESTMENT

A

tractor trailer is more than just a large piece of on-road equipment. It’s a major investment, foundation to a livelihood and a home away from home. Collectively, big rigs are the engine that keeps industries and economies in motion.

A new truck and trailer can cost well over a quarter-million dollars, and that’s not including a lot of chrome and aftermarket equipment so often added to personalize vehicles. And washing big rigs – from over-the-highway trucks to offroad energy-industry trucks – is infinitely more involved than washing cars. They’re bigger, sure, but they also come in a wide variety of sizes and shapes. That’s where innovative and creative plumbing technology can help.

With 21 years in the truck wash industry, Koro started his company in 1999. Designing superior automation and water treatment technology that can adapt to a very diverse trucking industry was key, but equally important was minimizing capital costs related to building and land, and developing a service and operational standard which allowed the business model to work.

“Until recently, little had changed in the truck wash industry in the past 40 years or so,” said Koro.

“We aim to provide a fast and affordable public wash that offers value and consistency while delivering what every owner wants: a clean and shiny truck.”

Koro’s wash system utilizes advanced technology that delivers a high wash quality with minimal labour costs.

Conditioned fresh water is used for the portion of the wash that uses cleaning chemicals, as well as during the final, spot-free rinse.

“We researched the trucking industry to determine the needs of the end user and tailored a system using innovative designs and vendors to complement the application with quality components,” said Koro.

The fresh water portion of the system includes filtration, scale prevention and reverse osmosis for uncompromising purity.

“Whether you’re washing an oil field truck covered in 5,000 pounds of mud or you’re cleaning a chromedout road truck, water is a huge consideration,” said Jyrki Koro, president of Truck Wash Technologies in Sault Ste. Marie, Ont.

All water from the wash bay passes first through a bar screen before moving toward one of three grit chambers.

A volume water heater, water softener, carbon filter and flow tanks complete the water treatment for all chemical application and fresh water rinsing.

SEDIMENT

REMOVAL Each Truck Wash Technologies system uses recycled water for the bulk of the washing process. Heavily soiled trucks can require as much as 12,000 gallons of recycled water, but never less than 2,000.

“We have off-road trucks come in with so much mud that it actually reduces the amount of cargo they can legally haul,” said Koro. “Needless to say, this cuts into their pay cheque.”

As the system’s moving gantry makes pass after pass over the vehicle, tons of sediment drains into an in-floor catchment system. A series of screens and settlement tanks strain solids from the liquid.

TWO TYPES OF FRESH WATER TREATMENT As fresh water comes into the facility from a well or municipal supplies, it’s treated for scale prevention either by TAC (template-assisted crystallization) technology or a traditional water softener with a brine tank.

A cluster of high-volume hydro cyclones provides a second level of water filtration, spinning fine dirt out of the stream in a centrifuge. Finally, a liquid polymer is injected into the water.

This substance binds any remaining fine solids together so that they settle out more quickly. All sediment is continuously removed from the wash water and dewatered for ease of disposal.

If it’s being used for high-pressure rinsing applications, water first goes through a 100-gpm anti-scale system for treatment before entering a large storage tank. This chemical-free, TAC anti-scale technology bonds calcium ions together so that they’re inert, and won’t build up on surfaces downstream.

For fresh water used during the chemical application process, a different antiscale approach is used.

“Because calcium and magnesium rapidly absorb the cleaning chemicals and render them less effective, we need to be absolutely sure that all minerals are removed from the water stream for chemical application,” Koro explained.

“TAC reduces scale buildup, but the ions are still in the water. A commercial water softener conditions the water used in the chemical application. This amounts to roughly 30 gallons per truck wash.”

Fresh water first passes through a large carbon filter that features automatic backwashing. The activated carbon in the large tank is generally used for dechlorination, removal of tastes, odors and as pretreatment for reverse osmosis systems. Chlorine destroys reverse osmosis membranes and polymerbased ion-exchange resins used in water softeners.

A spot-free, final rinse is the very last phase of a truck wash. For this, water is treated by a large reverse osmosis system. A 4,400 gpd (gallon per day) reverse osmosis system provides ample water volume. It removes any remnant of minerals that could otherwise create powdery-looking spots on vehicle surfaces after drying.

Three high-volume pumps provide water to various wash function in the wash process. In the background, five high-pressure pumps apply a final fresh water rinse.

ON DOWN THE ROAD A Truck Wash Technologies installation will service upwards of 1,000 trucks each month. As drivers wait 15 or 20 minutes for their rig to come out sparkling clean, they’re oblivious to the high-tech processes going on in the background.

Truck Wash Technologies currently has two truck washes in Canada, and a third under construction in Tacoma, WA. The company is slowly watching trends in the industry shift favorably.

M e c h a n i c a l

B u s i n e s s

“

Being the first mover in a large, untapped market, it’s imperative we remain involved in all facets of the truck wash business to maximize the potential for our customers’ success, Koro said.

The superior technologies we’ve developed and assembled speak for themselves.

CELEBRITY ENCOUNTER

By Adam Freill

A

sk Peter Mansbridge where some of his best work starts and he might chuckle and say, “At an airport.” The chief correspondent for CBC News and anchor of The National was discovered by a CBC radio station manager while making an announcement over the public address system in the airport in Churchill, Man. That seminal moment in 1968 launched a career, and a voice, that’s instantly recognizable to Canadians from coast to coast.

“I was 19, working for a small airline called Transair out of Winnipeg. I was doing everything from fueling planes to loading baggage to selling tickets at the counter,” recalls Mansbridge. “They sent me to Churchill to cover for a guy who was supposed to be on holidays for two weeks.

I got there and after about a week they called and said, ‘He’s not coming back, so you are staying.’

“It turns out, it worked out great.”

A month after his transfer to Churchill, Gaston Charpentier happened to hear the young future newsman over the intercom.

“I was calling the flight over the PA system in the terminal building and this fellow comes up to me and says, ‘Hey, you have a good voice. I’m the manager of the radio station here. I need a guy to work the late-night shift.’”

So that’s what Mansbridge did for the next year, working full-time at the airline and part-time at the radio station doing the late-night record show.

“And we are talking Churchill: population 1,000, at a radio station that couldn’t be heard five klicks outside of town, but it was fun and eventually they offered me a full-time job, and I switched into news,” he says.

Finding a Working Recipe It is often said that success comes from a blend of hard work and opportunity. Being discovered, by chance, at a small airport presented an opportunity for Mansbridge, but it takes more than just being found to build the type of career that makes one a household name in Canada.

“Success is often based on being in the right place at the right time, or getting a lucky break, but it is what you do with it,” he says. “I worked extremely hard. The odds were against me. I had no background in broadcasting. I had no background in news. I spent hours and hours of my own time listening to shortwave radio to listen to how others would do their thing.”

Broadcasts by the BBC, the CBC and other news teams would be his training grounds.

“I would listen to whatever I could to see how different people would do their work – not to copy them, but to understand what it is they were doing,” he says. “That’s how I learned to write. That’s how I learned to do interviews. That’s how I learned to edit.

“I worked seven days a week, 16-18 hours a day trying to make this work for me. And I was there for three years before I was given the opportunity to move south to the big network and work in the Winnipeg local

newsroom. And when I got there, the same thing started all over again.”

His hard work and eagerness to learn his trade earned him respect in the Winnipeg newsroom, which led to more learning opportunities and career advancement.

“I owe a lot to those people who were part of my life in the early 1970s.”

The Airport Can Be a Zoo Having good things happen at the airport might sound far-fetched, but not for Peter Mansbridge. Not only did he get his start in media in an airport, he also had one of his most recent forays into the spotlight kick-started by a chance meeting in, of all places, the airport security line.

“It is as crazy as how I got my start in broadcasting,” he says. “I was on my way out to give a speech in Vancouver, and I was going through security at Pearson, and the guy behind me says, ‘You are Peter Mansbridge.’ And I said, ‘That’s right.’

The role needed an approval from the CBC, and scheduling needed to navigate last year’s election, but in a matter of weeks from that chance meeting at the airport, Mansbridge had a new role to voice, that of Peter Moosebridge, co-anchor of ZTV News in Disney’s Zootopia.

“They wanted me to come down to Hollywood to do it, but I couldn’t do that because we were in the middle of the election campaign, so they organized a studio in Toronto,” reports Mansbridge.

“They had a big video hookup with the producers of the film in L.A. It was the real deal. It was pretty exciting. And I did my two or three lines and that was that.”

“Like most people in this business, I get that every once in a while, so I was polite. But then he says, ‘I was just talking about you in a meeting yesterday. We want to talk to you about a role in a movie.’”

continues on page 122

After hearing a brief description of the project, a Disney film from the team that made the blockbuster Frozen, Mansbridge says he was still in disbelief.

“I’m thinking, ‘Really? This is happening in the Pearson Airport security line?’” he says. “I said that I had to catch a plane, but gave them my card figuring that I would never hear from this guy again. Before the plane took off, I get this email from him, and he’s a vicepresident with Disney.”

Zootopia opened on March 4 and is currently in theatres.

DID YOU KNOW?

By Adam Freill

The last time Peter was in Churchill, he did an announcement over the PA system in the airport.

Getting over Rough Spots

On Climate Change and the Environment Having spent a considerable amount of time in the northern reaches of the country, Mansbridge has witnessed the realities of climate change first-hand.

“We southerners like to think of Churchill as north, but it really is not that far north. The major change that is going on due to climate change is going on much further north than Churchill,” he says. “Things are changing, and dramatically, and have been for the last 10 to 15 years.

The dance that can be necessary to deliver bad news to a client about an HVAC or plumbing system that needs a complete re-do isn’t all that dissimilar to the position that television interviewers can find themselves in when an interview goes south, and Mansbridge admits that he’s had a few of those moments during the 15,000-plus interviews he’s done over his career.

“Why does it always come to $12,000? That’s what I want to know,” he laughed as he considered the similarities of the two difficult positions. “Every time I’ve had one of these housing problems, it is always ‘$12,000 is going to fix this.’ It’s like it is some kind of magic number.

“When your readers are called in, they draw upon the expertise they have that those who called them don’t have. They use it professionally, and the end result is good for everyone,” he says. “In my case, when an interview is heading south, and they do, you have to draw upon your professional skills to try and salvage it, to try to get something out of it. In some cases it works; in other cases, it just doesn’t, and I think your readers understand that too. You’ll end up sometimes with clients who just won’t buy the argument and the explanation they are being given.”

“When trappers notice that all of the sudden there are different birds around, and other birds that they are used to aren’t there, and the fish are different, and the water is warmer and the ice is less, they go, ‘Wait a minute, something’s “When your readers are called in, they going on here,’” he explains. “And it is much more visible in the Arctic draw upon the expertise they have that than it is here.” those who called them don’t have. They And while the cause of these changes may be open to debate, there’s no harm in reducing one’s environmental footprint, he says.

use it professionally, and the end result is good for everyone.”

“I think we all have room to improve on this. Looking at more efficient ways of heating our homes, of driving our cars, of simply moving around and being aware of what’s happening in the much bigger picture,” he says. “There’s no harm in looking at better ways of conducting our lives because, in the end, it is often more beneficial to us and our pocketbook to do that.”

Should I Stay or Should I Grow?

rowth. This should be the holy grail of every business. Many contractors grow their businesses to the size they are comfortable with, and then stay there for the duration. This is fine if it’s what the owner is looking for; however, there can be significant advantages to growing one’s business, rather than maintaining the status quo.

Suppliers are always on the hunt for the next dealer. They need growth to satisfy their corporate bosses and if they can’t get it from their existing dealers then they need to add more. Therefore, it makes sense that suppliers will pay extra attention and often offer greater value to customers that are growing with them, strengthening the business relationship and earning both parties a good return.

MANAGE YOUR GROWTH CAREFULLY Growth is a double-edged sword. Not enough and your company will stagnate; too much and you can spin out of control. Remember that you can only grow as quickly as you have the resources, people and cash, to do the work. Most contractors fail not because they don’t have enough work but usually because they have too much.

In most areas of business, larger companies realize the advantage of better buying power to lower their costs. In today’s economic climate, the bottom half of your income statement – your expenses – needs as much attention as you can give it.

Growing businesses are also in a better position to attract top quality employees, provide competitive health benefits to keep them, and source the best business partners (such as legal, accounting and marketing) to help move their business forward.

Marketing on a Shoestring One of the best books I have ever read on business development for small companies is called Guerrilla Marketing by Jay Levinson.

He has a hundred ideas for reaching potential buyers on a shoestring budget. If you don’t have an unlimited advertising budget (and who does?) this is the book for you. It’s the best $10 you will ever spend.

124

M e c h a n i c a l

And, when you’re ready to move on, a growing business is much more attractive for a potential buyer.

MARKETING FOR GROWTH Growth is something that should always be on your mind. However, growing a business requires good marketing and most contractors don’t have a background in marketing. Even if we did have the knowledge, the marketplace and the business environment are always changing. So what is a contractor to do?

There is a simple matrix that marketers use to determine where to invest their resources in growing businesses.

Always start with your existing customers. The easiest thing to do is to sell the things you already do to the customers you already have.

If you have done a good job looking after them, they will look after you.

If they bought a furnace from you 12 years ago, maybe it is time for a new one. Not everyone wants to wait for their furnace to break down on the coldest night of the winter, and advances in technology can make it a compelling sales proposition.

Do all of your customers have HRVs? Do they have the latest in air cleaners, humidifiers or Wi-Fi thermostats? It has been my experience that a conversation about a system enhancement can often lead to an opportunity for a new system installation.

The next level of growth can come from selling new products and services to existing customers. I recall a customer who called me shortly after we had finished an installation, asking if there was something else he could buy from me. People like to spend their money with businesses they like and trust.

For years our customers asked us to do duct cleaning. We offered it to our existing customers first and it was a great success even as we climbed the learning curve. They were very forgiving. Listen to your customers, and they will tell you what they want.

The toughest thing for a business is to reach new customers.

The best choice for a small contractor is to seek out referrals.

Engage your customers in a referral conversation. Let them know at the outset that you will be asking them for a referral when you are done. With all of the online tools available today, your customers have plenty of opportunity to talk about you – both good and bad. Take the time to steer the conversation.

Lastly, after you have exhausted the first three avenues of growth, you can sell new products to new customers. I have never met anyone in our industry that has had a lot of success in this area, so enter with caution.

It’s easy to say that you can’t grow your business when the weather isn’t in your favour or the economy is suffering, but everyone is affected by this, and yet we still see the strongest contractors survive, and thrive.

DESIGN CONSIDERATIONS FOR T

he operating and standstill pressures of most R744 systems are higher than for other retail refrigeration systems, although many cascade and secondary systems have similar operating pressures to R410A systems used in the air conditioning sector. The higher pressures affect the designs and specifications of all system components and pipe work.

Table 1 shows pressures on the high side of the system for a “standard” system and a high maximum allowable working pressure (MAWP) system. High MAWP systems are specified to avoid relief valve venting on standstill, when the pressure will exceed the standard pressure-relief valve rating at ambient temperatures above 6°C (42.8°F), the saturation temperature equivalent to 40 bar (580 psi).

Components that are readily available for R410A systems can generally be used for subcritical systems with a MAWP of 45 bar (653 psi) on the high side. Components that are subject to a higher MAWP are specifically designed for R744.

The standstill pressure is the internal pressure of the system when it is not operating. The equalized pressure depends on the ambient temperature when below the critical point, and the system volume and refrigerant charge when above the critical point.

For many R744 systems, the standstill pressure is greater than the maximum operating pressure. When this is the case, systems are either designed with MAWP based on the maximum

Table 1: Typical R744 pressures in retail systems

Fixed Leak Detection Based on ASHRAE 15 and CSA-B52, refrigeration machinery rooms shall contain leak detection equipment located in an area where the refrigerant would concentrate in the event of a leak. The alarm level of the detector should not exceed the Threshold Limit Value of the refrigerant which, for R744, is 5,000 ppm.

MAWP based on the maximum operating pressure, in which case the pressure-relief valves will vent when on standstill unless there is some means of reducing the pressure, or the system is designed with MAWP based on the maximum standstill pressure.

All components and assemblies must be rated for the maximum allowable pressure of that part of the system. Pressure-relief valves must discharge to a safe place, ideally outside a building to an unoccupied area.

Cooling Capacity The higher gas density of R744 results in a high volumetric refrigeration effect compared to all other common refrigerants. This affects compressor displacement and the sizing of pipe work, evaporators and condensers.

The compressor power consumption for a given capacity is similar to that for HFCs, so the compressor motor/ displacement combination is different for R744.

Design for Ease of Service Systems should be designed with sufficient isolation valves to ensure safe access to components and parts of the system that will require service. Areas to target include liquid and suction filters, where a bypass should be fitted so the system can remain in service during replacement; oil separators; and pressure-relief valves.

If liquid can be trapped between valves, these sections of the system should include high-pressure protection. This can be achieved by fitting a pressure-relief valve (PRV) in that section of the system, or by installing a check valve and piping it to a section of the system that is protected by a PRV. Gauges or pressure transducers should be provided on the system to give an indication of the system pressures.

To make charging easier and safer, it is advisable to install a permanent charging point in an easily accessible area. This avoids the need to move heavy R744 cylinders to the plant area.

If R744 cylinders are stored on-site, they should be located in a gas cage, upright and secure, ideally outside a building.

Figure 1: Comparison of HFC and R744 capacities in typical systems

An R744 retail system will typically use fewer compressors than an HFC system of the same cooling capacity. This is because the higher capacity of R744 reduces the total compressor displacement required. Heat exchangers are often smaller, leading to more rapid changes in operating conditions when the load changes. Both factors increase the need for effective capacity control to meet a varying load.

Working with Smaller Pipes The refrigerant properties that reduce the required compressor displacement also allow smaller-diameter pipe work to be used. This is especially true in the suction line carrying superheated gas. The effect on liquid line size is lower because the volume flow is similar to HFCs. The heat transfer coefficient of boiling R744 is greater than for HFC refrigerants. This improves the performance of evaporators and condensers, which allows for either the use of the same sized evaporators and condensers, with greater heat transfer capability and hence lower temperature differences (TDs), or for smaller evaporators and condensers to be used. This reduces the component cost and space required. continues on page 128

REFRIGERATION

continued from page 127

The pressure drop in R744 pipe work and components is generally lower than with HFCs (especially in suction lines), and system performance is less sensitive to pressure drop. The system designer can therefore allow for a greater pressure drop. In general, refrigerant velocities are similar to those for HFC refrigerants.

The general rules of good pipe design should also be followed with R744 systems. Pipe thickness will usually be greater because of the higher pressures, and in some cases steel will be used in place of copper.

As explained previously, smaller diameter pipe is used in some parts of the system. This will inherently withstand higher pressures than larger diameter pipe of the same wall thickness. Table 2 shows the maximum pressure of a range of copper tube.

Comparison of pipe sizes for typical systems

Table 2. Rated Internal Working Pressure for Copper Tube (ASTM B280, ASTM B78)

*Using ACR (Air Conditioning and Refrigeration Field Services) Copper Tube

The most reliable method of jointing copper tube is brazing. The greater thickness reduces the opportunity to swage the pipe and therefore increases the use of fittings. In addition, the heat required for a brazed joint is greater to get the required degree of penetration.

LUBRICANTS AND OIL RETURN Polyolester (POE) lubricants have good miscibility with R744 and are predominantly used as compressor lubricants in retail R744 systems.

Because of the high solubility, higher viscosity lubricants are used when compared to HFCs. This reduces the effect of oil dilution by the refrigerant, maintaining lubricant properties.

Copper tube is currently available in Europe that is specifically for use on R744 systems with a MAWP of 120 bar (1,740 psi). This is known by the trade name K65 tube. The material comprises copper with 2.4 per cent ferrous, plus very small amounts of zinc and phosphorous. It cannot be bent or swaged, so it is joined using proprietary brazed fittings.

POE oils are very hygroscopic (i.e., they readily absorb moisture), so care must be taken to ensure moisture does not enter the system.

FASTFACT Steel pipe work is often used in R744 systems because of the high pressures, but steel can become brittle at low temperatures. In the event of a leak, the temperature can drop to around -78°C (-108.4°F), so low-temperature steel must be used.

R744 liquid is heavier than oil, as with HFC refrigerants. Effective oil separation and return to the compressor is necessary. Typically, this is best achieved by the use of coalescent-type oil separators and, for multiple compressors, a conventional oil-return system.

Hydronics

By David A. George

An in-depth look at

INDIRECT WATER HEATING Indirect water heating has been an established industry practice for decades, but it has grown in popularity in recent years due to interest in consolidating equipment and reducing mechanical footprints, as well as technical advances in boiler operation and control.

For high-end homes and light commercial applications with high domestic demand, indirect water heating delivers a compact design and fast, effective operation.

It also offers equipment longevity. Many of the residential indirect water heaters in the market today are highly durable and resistant to corrosion.

In addition, boilers have become more sophisticated.

Boilers now feature advanced burner/combustion systems that modulate from low BTU input to total BTU input. This allows the boiler to adjust the input rate to match a variety of demands for long, smooth burn without short cycling.

Indirect water heating is also effective with very hard water. In direct water heaters, very hard water can cause lime scale to build on the heat transfer surfaces. In an indirect water heater, the heat transfer temperature differential is comparatively low. This means less lime scale precipitation and less lime scale buildup on a heat exchanger that can be easily removed with annual cleaning.

For high-end “homes and light

commercial applications with high domestic demand, indirect water heating delivers a compact design and fast, effective operation.

”

GOING INDIRECTLY INSTANTANEOUS? A variation of indirect water heating is instantaneous domestic water heating. The idea is to use the building’s recirculation loop as the body of stored water. The loop is put into constant flow and as the hot water is drawn away, the indirect water heating equipment puts new heated water back into the loop.

Eliminating storage sounds tempting, but instantaneous water heating will not work in all applications. If the recirculation loop does not hold enough water to act as storage for the domestic demand, there will be problems.

Also, most instantaneous designs operate on the flow triggered by the fixtures. A single faucet can cause the boiler to fire, which is wildly inefficient.

TEMPERATURE AND CONTROL Hydronic systems and domestic water systems invariably operate at different temperatures.

For example, hydronic systems for building heat will operate on a system temperature that varies as the winter season progresses. In the shoulder months, the hydronic system may operate at temperatures below 100°F (excellent for a condensing boiler, by the way).

Then with an outdoor reset function, the hydronic system temperature will ramp up to as much as 180°F as the winter days get very cold.

Domestic systems operate at a consistent target temperature year-round. Most domestic systems operate at 140°F or higher as an effective safeguard against Legionella.

So no matter what temperature the hydronic loop requires to create the heat transfer for the domestic water, the boiler will always need to deliver high water temperatures, typically 180°F outlet water temperature.

To meet the operational requirements of two different systems, many residential and light commercial boilers feature advanced onboard control systems with

“domestic hot water” or “DHW prioritization.”

The control board’s DHW priority intelligence will monitor both the domestic and hydronic loads and make decisions on how to satisfy each demand.

SAFETY PRECAUTIONS Another important consideration with an indirect water heating system is glycol. The hydronic system and the

The boiler can quickly switch from hydronic heating to domestic water heating and when it does, it will drive up to high water temperatures to quickly recover the domestic demand so it can return to hydronic heating.

domestic water system

For example, a boiler is maintaining 90°F temperature in the hydronic loop on a mild autumn day. When switching to DHW priority, the control will ramp up to high input and 180°F boiler outlet temperature to recover the DHW demand quickly. When the domestic load is satisfied, the boiler will return to hydronic heating, reducing the input rate back down to maintain the 90°F temperature in the hydronic loop.

exchanger, since we

are separated with heat transfer passing through the sealed wall of a heat wouldn’t want glycol solutions to mix with the domestic water.

Many local authorities, fearful of this potential, require a double-wall coil.

Only install a double-wall coil if you are forced to by local code, however, since

transfer rates than singlewall coils.

Large convention hotels have a very sharp domestic water demand. Early in the morning, a majority of guests get up and hit the showers before the

convention. On a cold day, you would not want to have the domestic demand compete with the hydronic demand from the same boiler.

If the domestic water demand is very large, then you’d want to choose a dedicated hot water heating system.

Also, consider the equipment efficiency. When a boiler operates

at high temperatures to heat the 140°F or greater domestic water, the boiler is firing at noncondensing temperatures, putting the boiler’s thermal efficiency in the mid-80 per cent range. This occurs even if it is a condensing boiler by design.

Instead of putting a condensing boiler into inefficient non-condensing operation for long periods of time, it might be better to install a dedicated condensing water heater to take advantage of the cold city water and deliver thermal efficiency that’s pushing the upper-90s.

Many hydronic systems are seasonal, providing radiant heat in the building during the winter months but shut down during the summer. Some like the idea of adding domestic water heating so the boiler can be used year-round.

This idea works best when the boiler is piped directly to the indirect water heater in a separate branch from the hydronic system.

If piped as a zone, the hot boiler water for the heat transfer is in the main hydronic loop and care must be taken to keep the hot water away from the hydronic system where the heat would be wasted as it fights with the building’s cooling system.

You would also not want to meet a very small domestic load with a very large boiler. Consider a large commercial office building with multiple floors and multiple zones that use a large 5 million BTUH boiler. If the building also has a small domestic load for a shower or two in the office gym, fight the urge to put a small residential indirect (30 to 119 gallon), even if the boiler has a very deep turndown ratio like 25:1 or 30:1.

Instead, put in a small residential or light commercial water heater for the small domestic demand.

And always use propylene glycol; never use ethylene glycol. Food grade propylene glycol is non-toxic. Ethylene glycol is very toxic and should never be used in a hydronic system that is also doing domestic water.

Find the Fix

IS IT RUNNING, OR IS IT WORKING? This is an interesting job that has been worked on over the past two years. Each boiler is a 500,000 BTUH mod/con unit, with 1-1/2” boiler supply and return tappings. Several modifications have been made to the original installation that is shown here, but the fine-tuning is ongoing.

Check out the answer key for this quiz at www.mechanicalbusiness.com after April 1 to see the design-stage and current-state diagrams for the system. Our quizmaster would like to hear your feedback on some of the changes that have been made to the system.

And remember, although hydronics can be very forgiving and you might get heat out and get a system to run, that’s not the ultimate goal.

Following the simple basics of hydronics will help make it work as a system.

1. The existing pipe size to and from the boilers should be: a) 1-1/2”, same as the tappings on the boiler. b) 3” c) 2-1/2” d) 2” would work fine.

3. What simple changes could you make to have it “work” instead of “run”? a) It should have run fine, not sure why they changed it. b) The supply and return lines from the hydraulic separator should have been 3” to attach to the existing system. c) If a properly sized circulator had been added between the hydraulic separator and the existing building loop with properly sized supply and return lines, this would work. d) Forget the double reverse-return on the indirect coils and simplify the piping by essentially turning the double coil into a single coil indirect tank. e) Both b and d.

THERMOSTATIC CARTRIDGE

ADJUSTABLE LIMIT STOPS

TEMPERATURE ADJUSTMENT

ABOVE THE DECK CONVENIENCE. T H E R M O S TAT I C C O N F I D E N C E.

The new Delta hands-free thermostatic lavatory faucet is the smart choice for applications requiring thermostatic temperature regulation. The mixing valve and solenoid are contained within the body of the faucet and the supply lines are factory-installed, making installation quick and simple. Outlet temperature limits can be set easily from above the deck by the installer and a top mixer allows the user to adjust the water temperature to comfort.

Now thatâ&#x20AC;&#x2122;s smart.

et’s face it, measurement counts when it comes to mechanicals.

Whether you are sizing out a length of duct, or trying to ensure that a pipe or shower pan has an appropriate slope, numbers matter, as do the tools we use to build to those numbers.

When it comes to the tape measures used on the job, durability is a key factor. These tools suffer their fair share of falls, bent blades, scrapes and bumps as they get tossed into the toolbox at the end of the day.

A professional-grade tape will have been tested to ensure that it can withstand the type of fall that can happen as you try to loop it onto your belt, or as you ascend a ladder. Heavy-duty coatings on the tape can add durability, so that you can see the numbers for the life of the tool.

And pick a measure that has all the scales you use on a regular basis, perhaps drawing scales and linear measurements.

Magnets on the end of the tape can help for one-person tasks. Magnets can also be helpful when putting your professional-grade level to use on a jobsite. These can help keep a torpedo level in place on metal pipes when reading an angle or plumb.

Many levels also have a v-groove that can be used to keep the tool flush to non-ferrous piping.

Well Dressed As with tape measures, durability and Convenient and readability is key in a level, so A convenient feature that look for robust construction – onesome levels have added is a piece aluminum is nice – with reaming device. Rather than heavy-duty vials that are easy to read looking for a pocket knife or other tool to properly dress a and are designed to withstand the pipe, everything is right on the occasional fall. one tool. How convenient!
