< UPFRONT Bringing it home Several years ago, I suggested to some HVAC/R manufacturers that much of the manufacturing of these products would return to North America. Throwing caution to the wind, I insisted that this would largely happen in the next decade. Well, we are three years in and there has not been huge movement toward this outcome. Still, I am sticking to my guns on this one for several reasons. The first is quality control (particularly in component manufacturing), the second is the cost of transport/energy, and the third is consumer-based. In spite of a tight economy there are strong movements afoot to buy local, to buy Canadian or North American products, even if there is a price differential. The impact of natural disasters and epidemics on overseas manufacturers' ability to deliver, and the push to reduce inventory costs, are other reasons to bring manufacturing closer to home.

A report by The Boston Consulting Group (BCG) titled Made in America, Again: Why Manufacturing Will Return to the U.S., was released in August 2011. It predicted a reversal of the manufacturing exodus, which will accelerate as companies take into account the full costs of outsourcing to China and the strategic advantages of making products closer to North American consumers. Check it out online (www.bcg.com).

In this issue, we present the CMX-CIPHEX 2012 Show Guide, countless features aimed at making you more profitable and knowledgeable about the marketplace now and in the future, and Show & Tell â&#x20AC;&#x201C; a forum where industry suppliers present their stories to you, the end user.

Delta’s Touch2O.xt™ Technology for the Bathroom Today’s home technology anticipates the homeowners' need to make their life easier. But with so many choices in the marketplace, homeowners will be looking to you for trustworthy advice. Helping your clients select the best home technology means saving them lots of time. That’s why Delta introduced its Touch2O.xt Technology for the home. This electronic faucet is easy to install and provides the ultimate convenience to your clients. That way, they’ll know exactly who to call the next time they need advice.

DELTA FAUCET

PRESENTED BY

Hands-Free Activation

Delta’s Touch2O.xt Technology for the bathroom allows users to turn water on or off by simply approaching the faucet’s 4" sensing field or tapping the faucet anywhere on the spout or handle. The faucet automatically turns itself off after hands are removed. The added convenience of hands-free activation means the faucet stays clean even when hands are messy.

538T-SS-DST

Water Savings

A surprising 70 per cent of Canadians admit to leaving the water running while brushing their teeth according to a recent Angus Reid survey commissioned by Delta Faucet. Touch2O.xt Technology makes it convenient to turn water off while brushing teeth and shaving. Users that turn off the water every time they brush their teeth could save up to nine gallons of water every day!

592T-SS-DST

Parent Tested, Parent Approved

Delta’s Touch2O.xt Technology has been given a “Parent Tested, Parent Approved” Seal of Approval. Families across North America put the faucet to the test in their homes and found it useful in their busy day-to-day lives. For clients with children, this technology makes morning rituals and washing up fun! Faucet handles can be difficult for kids to turn, especially at a lower height, but Delta’s technology makes it easy for them to wash their hands and brush their teeth independently.

Touch2O.xt Technology is available in two styles: Addison® and Lahara®. Both models operate with six AA batteries.

Heating and Cooling Controls Leading the Way in Heat Pump Control

TEKMAR CONTROL S Y S T E MS

PRESENTED BY

The tekmarNet速2 House Control 406 is designed to operate the equipment in a 2-pipe, single tank, hydronic heating and cooling system. It operates two heat pump stages (water-to-water or air-towater) with a backup heat source (boiler or electric resistance).

Harness The Power of System Integration Through One Control To get the best performance out of a heat pump system, the interaction between the zones, heat pump, domestic hot water and the backup heat source must work together in an organized and intelligent way. Get the entire system working together to improve system efficiency, reliability & energy savings.

System Integration Optimizes Heat Pump & Backup Operation Heat pump applications may require a backup heat source to provide additional capacity when a heat pump alone is not sufficient. Common heat sources could include electric resistance, modulating condensing boiler or on/off non-condensing boiler. The tN2House Control 406 will maximize operation of the heat pump by monitoring existing conditions. If conditions are not optimal, the control will enable the backup to satisfy the heating load.

System Integration Improves Heat Pump Performance Current heat pump applications operating with stand-alone setpoint or outdoor reset controls do not achieve their highest performance. During heating, heat pump performance can be improved with lower return water temperatures. The tN2 House Control 406 will target the lowest water temperature possible while still maintaining a comfortable temperature in the space. This is achieved through integration of outdoor reset & communicating thermostats, which provide indoor temperature feedback.

System Integration Provides Intelligent Heat/Cool Switchover A single tank 2-pipe system can only operate in either heating or cooling mode.

The tN2 House Control 406 polls the thermostats to determine requirements for heating or cooling. When enough thermostats require the opposite mode, an automatic switchover occurs. In heating mode the 406 control forces the cooling zones off, likewise, if the control is in cooling mode, the heating zones are forced off. This more intelligent switchover maximizes overall system performance to better meet the requirements of the building. This function addresses the main challenge currently being faced of manual switchover between heat/cool system operation.

HRAI COMMENTS ON FEDERAL CODE OF PRACTICE Warren Heeley, president of the Heating, Refrigeration and Air Conditioning Institute (HRAI), recently forwarded a lengthy list of comments to Environment Canada on draft revisions to the Code of Practice for Elimination of Fluorocarbon Emissions from Refrigeration and Air Conditioning. The content from this code is used for the Environment Canada environmental awareness course required in most provinces for purchase of fluorocarbon refrigerants. The comments were a compilation of input from HRAI members and instructors.

In the general comments submitted, HRAI pointed out the importance of the Code as a resource for the Environment Canada and provincial training courses concerning environmental awareness for refrigerant use. HRAI felt the draft “missed the mark in trying to improve a reasonably well written document that needed some minor updating and reorganization versus a total rewrite. The draft is at best confusing and misleading in a number of technical areas.”

HRAI’s comments also expressed concern about new areas on energy efficiency, instrumentation and life cycle costing that have no direct link to the work performed by individuals who service, install, maintain and decommission refrigeration and air conditioning equipment. In addition, there is considerable information on flammable refrigerants that is misleading to the reader and/or refrigerant handler.

According to HRAI, the way the draft Code is written, leads the reader to believe that the use of flammable refrigerants is a viable option to consider when servicing all types of existing refrigeration and air conditioning products and systems including conversion options. Flammable refrigerants are not continued on page 22 hpacmag.com

New Additions to Flexible Connections Line Boshart Industries has added new products to its flexible connections line, which includes elbows, tees, tubular traps and drain and trap connectors. These fittings are moulded from UPVC (Unplasticized Polyvinyl Chloride) for durability and steady performance. They provide a quick and flexible connection for above ground application of drain, waste & vent piping. Installed easily in confined spaces, they also offer a reliable solution for repair jobs where a fitting has been cut out.

All fittings come complete with 300 series stainless steel clamps for a secure leak proof seal. Joining the flexible connections are the No-Hub couplings, which are shielded couplings for joining hubless cast iron pipe, plastic, copper, steel or lead in drain, waste and vent applications. The 300 series stainless steel constructed corrugated shield and clamps are connected by floating eyelets allowing them to work independently from each other to produce a positive seal.

Liberty Pumps Introduces the ASCENT II Macerating Toilet

LIBERTY PUMP S

PRESENTED BY

The new Ascent II macerating toilet system from Liberty Pumps allows easy installation of a bathroom in areas where no gravity sewer lines may exist!

Perfect for remodeling applications, the Ascent II eliminates the need for major construction or breaking concrete floors in basements to add a bathroom.

Featuring a 1.28 GPF (4.8 LPF) high efficiency toilet, the system easily macerates sewage waste and other debris with new RazorCut™ technology and then discharges it through a small 1” diameter line up to 25 feet (7.6 metres) high and 150 feet (46 metres) horizontally.

With tens of thousands of cycles and months of testing in a commercial installation, the RazorCut™ system easily handled sanitary napkins, paper towels and other difficult solids with ease. If something undesirable – such as a child’s action figure or toy were to get accidentally flushed, a removable service panel provides quick access to the cutter area without disconnecting the plumbing. A safety switch designed into the access cover automatically disconnects power when the cover is removed. This assures the unit will not energize while performing service.

Other features include IST™ solid state switching with Advance-Run-Technology. This unique feature assures the RazorCut™ system is spinning at full RPM prior to fluid and waste entering the cutter basket - greatly reducing startup load and improving macerating performance.

The system also features a built-in alarm with battery backup, rear discharging connections to eliminate unsightly rubber connectors and pipes exiting the macerator cover, LED lights and an external touchpad for alarm silence and manual system override.

The ADA compliant toilets – available in round front and elongated styles, have improved flush performance and carry the WaterSense™ mark. Both models feature insulated tanks to eliminate sweating.

commercial incentive programs and venting issues on the radar in Saskatchewan SaskEnergy, SaskPower and SaskEnergy Network Members have introduced two energy efficiency programs for commercial properties: the Commercial HVAC Program and the Commercial Boiler Program. The Commercial HVAC Program offers financial incentives to commercial property owners that upgrade/install HVAC equipment with high efficiency natural gas furnaces, boilers and/or rooftop units. The Commercial Boiler Program is available through the SaskEnergy Commercial Network Members and offers incentives designed to offset the incremental cost of a natural gas condensing or near-condensing boiler and high efficiency circulating pump over the cost of a standard-efficiency boiler and single speed pump. High efficiency pumps now qualify for incentives. www.saskenergy.com SaskPower recently released a bulletin responding to questions posed about sidewall venting requirements within 22

Expo breaks previous records The 2012 AHR Expo that took place from January 23-25 at McCormick Place in Chicago, IL. saw more than 58 000 total attendees and nearly 40 000 visitors, breaking the show’s previous record of 38 534 visitors that attended the 2008 show in New York City. The 2012 show also broke its previous record for largest show, with this year’s event measuring in at approximately 430 000 sq. ft., surpassing the 2006 show in Chicago, IL by nearly five per cent.

Clay Stevens, president of International Exposition Company, attributed the attendance records to new energy-efficient technologies and products in the marketplace and pent-up demand for new equipment.

There were 1968 exhibitors from 35 countries at the show and more than 100 education sessions offered by ASHRAE and other industry-leading organizations. www.ahrexpo.com hpacmag.com

The Technical Standards & Safety Authority (TSSA) issued an advisory (Ref no. FS-187-11) regarding Navien instantaneous hot water heaters. The advisory states that the joints for the entire venting system of all Navien water heaters manufactured between February 29, 2008 and December 31, 2008 must be re-inspected to ensure they are properly fused, to prevent any potential flue products – including carbon monoxide (CO) – from being expelled into the living space.

The lack of fusing between joints has been attributed to an inadequate application of cement. Navien has requested installers to inspect any Navien water heaters manufactured through the end of December 2008 to ensure all collar and exhaust sections are fused appropriately. The company has stated that application of ULC S636 compliant cement – in accordance with the cement manufacturer’s instructions – will be required for collar and exhaust sections improperly fused.

Navien stated it has tested and approved the use of IPEX System 636 and Royal Group GVS-65 cements for fusing Navien water heater collars to PVC venting pipes.

The manufacturing year is located in letters five through eight of the 16-digit serial number (Example: XXXX2008XXXXXXXX).

Protecting wood-fired boilers from low water temperatures.

O

ver the years, many of my articles in HPAC have described the need to protect conventional oiland gas-fired boilers from sustained flue gas condensation. To recap: Whenever a hydrocarbon fuel is burned, one of the byproducts is water vapour. If the temperatures in the combustion chamber, flue, and chimney are high enough, this vapour passes through, and is released outside without creating problems. However, if the surface temperatures of the chamber, vent connector, or chimney are too low, the vapour condenses into a liquid that can be highly corrosive to steel and iron surfaces. It can also damage masonry chimneys. These situations must be avoided to ensure a long and efficient life cycle of steel, cast iron, and copper tube boilers.

A similar situation presents itself when the fuel is firewood, wood pellets, or wood chips. When wood is sufficiently heated, it gives off pyrolytic gases. Given high enough temperatures and sufficient oxygen, these gases combust to produce heat. However, if the temperature in the combustion chamber is too low, or the combustion zone is starved for oxygen, a significant portion of the pyrolytic gases will not combust. Instead, these gases condense into a sticky, tar-like substance called creosote that accumulates both within the combustion chamber, as well as the vent connector and chimney flue, as shown in the photographs below.

Creosote build up in vent connectors and chimneys is extremely dangerous. Because it is formed from unburned

BY John Siegenthaler

hydrocarbons, creosote has considerable fuel value. If sufficiently reheated by other combustion products or flames, that fuel value can quickly reappear as a chimney fire.

Such fires can create extremely powerful convective air flow within the chimney that further increases the fire’s intensity. Some chimney fires can destroy the chimney’s integrity within minutes, and then quickly spread to the building structure.

Over time, creosote build up on the walls of a boiler’s combustion chamber can also cause pinhole leaks, and thus ruin a major and expensive portion of the boiler.

Creosote build up can be limited by burning only dry firewood. Maintaining a minimum inlet water temperature to the boiler can also reduce it. The latter detail keeps the walls of the water-cooled combustion chamber above the temperature at which pyrolitic gases condense into creosote.

The specific boiler water inlet temperature that provides this protection depends on the moisture content of the firewood, as well as the amount of air passing through the combustion chamber. Figure 1 shows how the dewpoint temperature of the flue gases varies within these parameters.

The air/fuel ratio is the ratio of the actual amount of air supplied to the combustion process divided by the minimum amount of air needed to completely burn the fuel.

Supplying excess air to the combustion process creates a drying effect that lowers the dew point of the flue gases.

Creosote accumulates in the combustion chamber and the chimney flue and vent.

One way to protect a wood-fired boiler from operating at low inlet water temperatures is to install a “loading unit” as shown in Figure 2.

A loading unit combines the functions of a thermostatic mixing cartridge, a circulator, and flapper-type check valve.

Some loading units also have thermometers and isolation valves on all three piping connections.

Loading units regulate how fast the heat produced within the boiler is allowed to move to the load. They act like the clutch in a car – regulating the rate at which energy is passed from the source to the load.

When the boiler is first fired, its outlet water temperature is well below the temperature setting of the thermostatic cartridge in the loading unit. Under this condition, the cool water inlet port of the loading unit is fully closed and the hot water inlet port is fully open. All water leaving the boiler is routed directly back to the boiler’s inlet. The circulator within the loading unit produces all necessary flow. No water is routed to the load. This operating mode allows the boiler temperature to rise as quickly as possible, and minimizes the potential of creosote forming within the combustion chamber or venting system.

Once the boiler’s inlet temperature rises a few degrees above the temperature setpoint of the loading unit, its internal thermostatic cartridge moves to allow some cool water from the return side of the load to mix with hot water entering its top port. This internal mixing action is shown in Figure 3.

The loading unit continues to monitor boiler inlet temperature as it allows hot water to pass to the load. If the boiler’s inlet temperature rises, the loading unit allows progressively more hot water to pass from the boiler to the load, and vice versa. The net effect is that a loading unit does not allow the load – whatever that happens to be – to “gobble up” heat faster than the boiler can produce it.

However, as more air is supplied, more heat is carried away in the exhaust stream. The higher the moisture content of the firewood, the higher the dew point of the flue gases. Properly seasoned firewood should have a moisture content no higher than 20 per cent.

Lower flue gas dew point temperatures are desirable because they allow the boiler to operate with lower jacket heat losses. A minimum boiler inlet temperature of 140F is generally considered adequate to protect boilers operating with seasoned firewood.

LIGHTS OUT Another unique feature of some loading units is their ability to allow natural thermosyphon flow between the boiler and load during power outages. This operating mode helps prevent excessive heat buildup within the wood-fired boiler that might eventually cause the pressure relief valve to open.

During a power outage, a lightly loaded flapper valve within the loading unit is pushed open by the slight pressure differential created by buoyancy effects generated by hot water in the boiler and cooler water in the distribution system or thermal storage tank, as shown in Figure 4.

When power returns, the flapper is pushed shut by the pressure differential created by the circulator.

Notice that a swing check valve is also installed near the inlet connection of the thermal storage tank. Its purpose is to prevent reverse thermosyphoning between the tank and boiler piping when the boiler is off. The forward opening resistance of a swing check valve is very low, and presents miniFigure 4 swing check to load cooler water descends in tank

mal interference with the desirable thermosyphoning effect during a power outage. Never use a spring-load or weightedplug check valve as a substitute for this swing check valve.

Loading units with an internal flapper valve, and piped as shown in Figure 4, usually eliminate any need for other “heat dump” provisions in the system. The labour and materials required to install such heat dumps can cost considerably more than installing a loading unit.

DESIRED DETAILS In addition to installing loading units, some wood-fired boiler manufacturers recommend additional installation details to minimize formation of flue gas condensate and creosote. These include: • Use only insulated stainless steel chimneys and vent connector piping.

• Use a buffer tank to allow for longer burn cycles at elevated combustion zone temperatures. This is especially important for wood gasification boilers. Longer and hotter burns help maximize thermal efficiency.

There are other ways to protect wood-fired boilers from low inlet water temperatures. A variable speed “injection pump” installed between the boiler and storage tank, and configured for dedicated boiler protection is a possibility for systems larger than what currently available boiler loading units can handle. However, for residential and light commercial applications, it is hard to beat the simplicity, reliability, and multi-functional characteristics of a boilerloading unit. <> John Siegenthaler, P.E. is the author of Modern Hydronic Heating (the third edition of this book is now available).

K I DZ bathrooms for

By Andrew Snook

When people start their families, they often like to envision how the baby’s room will look. Whether its furniture colours, or the types of cartoon characters that will decorate the walls, the room is usually designed for the child; however, when it comes to planning the design of a bathroom, parents tend to choose child-friendly products over child-specific products, and that demand is dictating the design of many products coming into the marketplace.

“If we design something that’s blatantly for kids it tends not to sell,” says Gray Uhl, director of design at American Standard. “If we design something that is obviously targeted at kids, people consider that — in the realm of how long they’re committing to on a plumbing project — too short a time span. The permanence of plumbing is not an area where they’re going to select something that’s going to be fun for kids for three or four years of their lives.”

D

onna Church, marketing and communications manager for Kohler Canada, says consumers are looking to get increased use out of the products they purchase for a bathroom for kids, and that the market has adjusted to offer those options.

“In recent years there has been a shift in products that can provide flexibility and room for adjustment; this is a huge benefit for a children’s bathroom,” she says.

Church adds that designing a bathroom that can be adjusted to suit a growing child’s needs is cost-effective.

Church says consumers have also been moving away from bright colours in the bathroom over the past year as well.

“Kids adore colour, but a bathroom overtaken with bright hues can feel overwhelming and may grow out of date quickly,” she explains. “A trend we are seeing more this year is neutral, earth-toned backdrops with bursts of colours strategically placed in accents like fixtures, towels, shower curtains or wall murals.”

Maria Bosco, marketing, communications and training manager for Grohe Canada, says most parents are heading towards the child-friendly route, with a smaller segment of the population — with greater disposable incomes — focusing more on child-specific bathrooms.

“For the regular parent, they are going to go [the child friendly] route,” Bosco explains.

“For someone who has tons of dollars, they might go for the more unique products specifically for children — the lavatory basin that’s Walt Disney scened [for example].”

Although American Standard tends to gravitate away from kid-specific products, Uhl says children are considered in the majority of the designs.

Some examples of child-friendly products Uhl mentions are single-control bath faucets with hot water limit safety switches, pressure balancing valves or thermostatic valves for tubs and showers, and dry and safe storage areas for bath-time toys.

Anita Griffin, marketing brand manager for Masco Canada Ltd., which represents numerhpacmag.com

ous brands including Delta, BrassCraft, Axor, Brizo, Delta Commercial, Hansgrohe, Motiv, Alsons, Master Plumber, PlumbShop and Waltec, says a big selling point for parents are products that are fun, safe, stylish and make children’s daily bathroom routines easier.

“Whether it’s convincing them to brush their teeth after meals, wash their hands when they get home from school, or take a shower or bath before bed, most children are less than enthused about bathroom hygiene,” Griffin explains. “Any time parents can come up with creative, fun ways to encourage children to engage in routines, the more success they will have.”

Another product designed with kids in mind is the Flowise Modern Handheld Shower from American Standard that comes equipped with an adjustable height bar.

“It’s so much easier to clean the tub and wash them out,” Uhl explains.

“As kids transition [from bath to shower], it allows them to adjust it to

The Rainshower Colour Collection from Grohe is another option for consumers looking to design a kidfriendly bathroom. It is a collection of showerheads and hand showers that are designed in six different colours to appeal to kids.

“The handheld version has a button on it so you can reduce the flow, so when you’re washing their hair it’s a little more gentle for them,” says Bosco.

D

CHANGES IN TRENDS Despite the demand for child-friendly bathroom products that accommodate every member of a household, there is still some demand for childspecific products. Uhl says this is mainly due to two changes in trends: changes in house design and the aging boomer population.

He says many homes are designed now with a bathroom for the adults and another for the children, and in some more luxurious cases, a bathroom for every bedroom.

“The notion that there’s one bathroom that everyone in the family uses is dating really fast,” Uhl says. “The adults in the house use a different bathroom than the kids use. That’s allowed a lot of growth for kids’ products that are friendly to them.”

E

He adds that more “well-to-do” parents may decide to design a bathroom specifically for their children, and that the aging baby boomer population whose children are grown up and out of the house may also decide to customize a bathroom for their grandchildren.

“If the boomer grandparents did okay, then they may have a special bathroom or give an extra effort to a kids’ bathroom,” Uhl explains.

Many of the vanities, countertops and toilets on the market currently have been raised in height to accommodate an older demographic, but child-friendliness has still been infused into the products.

Uhl says he had an epiphany as a product designer for one kid-friendly bathroom product after an experience with his son.

“My son had one of those little wooden step stools that sat in front of the sink that he would stand on when he was using the sink. It was annoying to me because it was always in the way whenever I went into that bathroom. So,

when he reached a point where I thought he was big enough and old enough that he didn’t need that step anymore, I took it away. A couple of days later he’s getting ready for bed and I’m walking by his bathroom at bedtime and I look in–and much to my horror–there he is in the bathroom standing on the toilet seat, leaning over, hanging on with one hand to the sink and the other hand brushing his teeth.

“We have vanities now that have an internal pullout step. It looks like a perfectly normal piece of bathroom furniture with a tow kick with non-skid material that has pullout steps for kids to use, now that the vanities are upwards of 36-inches high,” said Uhl. Whether parents and grandparents are creating a bathroom with childfriendly fixtures in mind, or designing a bathroom specifically for a child, kids will always be a driving force in the industry’s design and marketing of its products. <>

It Is A Digital Age

Matching capacity with system load can now be done very precisely.

t is morning again… you get ready for the day and make your way out to the garage where your car is waiting for the morning’s commute to work. You start the engine, make sure your radio is tuned to your favourite morning show and carefully back out of the driveway. Then you “put the pedal to the metal” and take off at full speed to the first stop sign. At the last moment you slam on the breaks, coming to a screeching halt just before the pedestrian walk. After making sure it is safe to proceed, you take off… once again at full speed. While this style of driving might get one to work, it is hardly an efficient way to drive (not to mention that it is unsafe).

The accelerator was designed for a specific purpose…to match the engine’s speed with the driving requirements at any given moment. Why has it taken our industry so long to see the logic in such an approach?

Compressors are selected for an application’s design condition, typically the worst case scenario in the middle of the summer, thereby ensuring that there is sufficient capacity to provide adequate comfort cooling (or product temperature in refrigeration applications) under all circumstances.

One of the factors influencing compressor capacity is the condensing temperature, and this is directly affected by ambient temperature. In fact, as the condensing temperature increases, the compressor capacity decreases.

For example, a semi-hermetic compressor model has a capacity of 50 500 Btu at a -20F SST and a 105ºSCT. During the cooler months where the condensing temperature can be maintained at 70F, the compressor capacity increases to 66 500 Btu. Now think about that for a moment. The system load is typically at its highest during the peak ambient temperatures in the summer. This is the condition at which the equipment is selected to ensure that there is sufficient equipment capacity during the most miserable of conditions. As the load decreases with a drop in ambient temperature, the compressor capacity increases. In other words, even though the speed limit has decreased to 40 km/hr, we are still driving with the engine at full speed. It is time to implement an accelerator to limit compressor capacity.

Certainly compressor unloaders have been around for years. For example, a particular model of reciprocating

“The accelerator was designed for a specific purpose…

to match the engine’s speed with the driving requirements at any given moment. Why has it taken our industry so long to see

the logic in such an approach? compressor (four cylinder) will allow unloading of one, two, or three cylinders allowing the compressor to operate respectively at 75 per cent, 50 per cent, or 25 per cent of capacity. Cylinders that have unloader capability are fitted with an unloader power element, which is activated by oil pressure available from the compressor’s oil pump.

Prior to the compressor starting, the lack of oil pressure allows the spring in the unloader power element to position the lift fork whereby the unloader sleeve is lifted up, preventing the suction valve disc from seating. Once the compressor starts, normal oil pressure will pressurize the power element piston, repositioning the lift fork and allowing the unloader sleeve to drop, putting the suction valve disc to seat. Once the suction pressure of the system reaches the set-point of the unloader capacity control valve, it will open up a passage allowing oil to the unloader power element to bleed off, reducing the pressure on the piston and causing the spring to move the unloader fork, lifting the unloader sleeve up. With the suction valve disc now temporarily lifted off of its seat, this cylinder’s pumping capacity has been reduced to zero.

There are two problems with compressor unloaders.

First, from a capacity control standpoint, it is unlikely that the percentage of the compressor’s unloading capability (in this example 25 per cent, 50 per cent, or 75 per cent) would match the reduction in system load. So, this sets up an operational pattern where the compressor unloads, the suction pressure rises, the compressor loads again, etc.

This is like taking an all day drive across the country where the speed limit is 110 km/hr, and operating the accelerator such that you are oscillating between 90 km/hr and 110 km/hr every five minutes.

Secondly, no compressor is designed to run unloaded for extended periods of time. Because operating unloaded reduces the system mass flow, meaning that the mass flow of refrigerant vapour returning to the compressor is reduced below the design condition; in this case somewhere between 25 per cent to 75 per cent reduction. It is a fact that compressors will pump a small amount of oil into the discharge line along with the refrigerant while in operation.

This oil must be returned at the same rate; otherwise a loss of proper lubrication might occur. The reduction in mass flow resultant from running unloaded will reduce rehpacmag.com

frigerant velocity, possibly affecting oil return. In addition, the reduced mass flow will reduce the amount of compressor cooling available from returning suction vapour, possibly leading to elevated compressor operating temperatures.

While reduced mass flow and its resultant potential problems cannot be eliminated regardless of the method of compressor capacity control employed, there are other methods available that will better match the compressor capacity with the system load.

Variable frequency drives (VFD) are a definite option in looking at a more efficient method of matching compressor capacity with the system load. While this subject is complex enough to be the subject of a future feature, suffice it to say that the VFD will vary the frequency of the AC power being supplied to the compressor, thereby varying the compressor speed. If the VFD is responding to suction pressure, it is possible to vary the compressor speed (within the safe operating band of the compressor) so that the compressor will maintain a constant suction pressure regardless of the load.

Recent developments in compressor technology have presented additional options for more precisely varying compressor capacity to match the system. continued on page 42

continued from page 41

HOW IT WORKS While scroll compressors have been in use for some time, it was not until 2000 that digital scroll technology was available for commercial HVAC applications.

As a review, the scroll compressor design and operation is as follows: Two interleaving scroll plates are used; one fixed scroll is attached to the compressor body and one orbiting scroll plate is coupled to the compressor crankshaft (see Figure 1).

The orbiting scroll plate, as its name implies, orbits rather than rotates.

Pockets on the outer portion of the Figure 2 Digital Scroll Design

Figure 3 Digital Scroll Cycle Times

scrolls draw in suction vapour. The pockets become smaller during the orbiting motion resulting in a high pressure/high temperature vapour, which discharges in the center of the scroll plates.

The digital scroll differs in design (see Figure 2) in that has the ability to relieve pressure on top of the fixed scroll plate by means of energizing a solenoid valve, which is piped from the scroll modulation chamber to the suction inlet of the compressor.

When this occurs, a spring separates the scroll plates by 1 mm; enough of a distance to completely eliminate

the scroll plate’s ability to compress vapour. The result is 100 per cent unloading capability.

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

Plainly speaking, the compressor operation can be broken down into cycles of 20 seconds, with a portion of the 20 seconds operating completely loaded, and another portion of the 20 seconds operating completely unloaded (See Figure 3).

When operating in its reduced capacity mode, the compressor capacity can be calculated from a ratio of percentage of loaded state time to the total cycle time. For example, if the loaded state time were 10 seconds, and the total cycle time were 20 seconds, the compressor capacity would be 10/20, or 50 per cent of capacity.

Given the wide range of capacities with which the digital scroll can operate under, it can offer a very precise solution for matching the compressor capacity with the system load. Not only can design parameters be maintained more closely, but there is the added benefit of an opportunity for energy savings…all thanks to the digital age we live in!! <> Dave Demma holds a degree in refrigeration engineering and worked as a journeyman refrigeration technician before moving into the manufacturing sector where he regularly trains contractor and engineering groups.

A Powerful Tool

Using thermostats with slab sensors allows for unique comfort control options and strategies. BY mike miller

U

nderstanding how slab sensors work for radiant heating is important as that knowledge offers many advantages to the contractor. We have to start with the assumption that the end user only knows a thermostat as an air temperature-controlling device. For that reason it is important to explain to the end user how a slab sensor affects the thermostatâ&#x20AC;&#x2122;s operation. A slab sensor is often added to protect surface coverings and/or to maintain a minimum comfort level.

INSTALLATION OF A SLAB SENSOR Slab sensors are connected most often to a thermostat that has a remote sensor connection. If not, they could connect directly to a water temperature controller, but for todayâ&#x20AC;&#x2122;s interest, we are connecting it to a thermostat.

While exceptions do exist, the slab sensor is commonly installed within two or three feet from the wall that the thermostat is mounted on, keeping the run of sensor wire often within seven to nine feet. Depending on the floor construction, the installation methods can vary (see Figures 1 to 5). Its very important to have the sensor installed just below the finished surface and it should be located half way between two pipes, in order to avoid it incorrectly picking up the water temperature within the pipe.

PROTECT SURFACE COVERINGS Subject to the finishing construction, it may be necessary to protect surfaces from excessive high temperatures that could be damaging to the product. A good example of that could be hardwood flooring. The highest allowed surface temperature may vary depending on the material manufacturer. I have seen it range between 82F and 86F. This would be Slab MAX, a high operating limit application.

with radiant floor heating alone.

The Slab MAX setpoint is often fixed by the installer and hidden away from the end user's adjustment capability.

The Slab MIN, however, is a comfort setting and often available for the end user's adjustment.

OPERATION WITH SLAB MAX A single stage thermostat would modulate the floor to whatever temperature it needs to be in order to maintain and satisfy an air temperature setpoint. As soon as the floor temperature becomes equal to Slab MAX, the air temperature setpoint operation of this thermostat is suspended and under-heating may occur (depending on zone load).

If the air temperature setpoint cannot be met with a floor at its Slab MAX, then an auxiliary stage of heat must be applied and a two stage thermostat used. An auxiliary stage of heat could come from several types of sources, including fan coils, baseboard, radiators or a panel radiator with high output at low temperatures.

With the floor at its Slab MAX, the thermostat controls the second stage to maintain the desired air temperature setpoint.

OPERATION WITH SLAB MIN Regardless of single-stage or two-stage, the thermostat would modulate the floor to whatever temperature it needs to be in order to maintain and satisfy an air temperature setpoint. As soon as the floor temperature becomes equal to Slab MIN, the air temperature setpoint operation of this thermostat is suspended and over-heating may occur (depending on zone load). The floor is not allowed to drop below Slab MIN setpoint.

Figure 1 Slab Sensor Embedded in Slab

MINIMUM COMFORT LEVELS In some areas of a building, it may be desired to keep the floors warm, regardless of air temperature. Examples include bathrooms, kitchens, children's play areas, or maybe even commercial workshops and car garages, or outdoor patios. These would be Slab MIN (minimum operating limit)applications.

In any case, Slab MIN and Slab MAX are operating limits that cannot be exceeded and could limit the thermostat from controlling the air temperature to its desired setpoint 44

HPAC | March 2012

hpacmag.com

Figure 2 Thin-set Application

Figure 3 Joist Trak Application

Figure 4 Tile Floor Covering Application

Figure 5 Subfloor Application

When the zone's load is high, then the floor surface is more likely to be near Slab MAX. When the load is light, then the surface temperature is more likely near the Slab MIN. If the thermostat is a heating and cooling thermostat and cooling is done by means other than radiant (could be fan coils), then the Slab MIN setpoint can be used to provide floor warming while providing air cooling. This is when it becomes potentially counterproductive and less efficient, as the result may be two fighting systems if set incorrectly. I have had several end users tell me that warm floors of 77F and cooled air at 74F is very comfortable. Who am I to argue with that thinking?

Even if the Slab MIN is set lower than an air cooling setpoint, the slab sensor can help take perceived chill out of the floor. Whenever the floorâ&#x20AC;&#x2122;s surface temperature is equal to or less than air temperature, it does not give up any heat to the space.

Some thermostats available today allow for control of two different Slab MIN Setpoints: One in heating mode and one in cooling mode. Slab MAX is usually the same for both. This allows for greater flexibility and comfort control.

What if the thermostat is also programmable and offers setback capability? The above still applies, except that you may now have a heating mode Slab MIN and a cooling mode Slab MIN for both Occupied and Unoccupied events.

This could be used to enable floor warming only during specific hours of operation.

Learning and understanding the Slab MIN operation, together with scheduling capability, allows us to combat slow response times of zones with a lot of glass exposure, such as sun rooms. The high amount of solar gain may force a zone into cooling mode for most of the day. In the evening, however, when the sun goes down and the solar gain stops, heating may be required again. If the radiant is installed in a high mass application (poured), then the response time can be significantly reduced if a Slab MIN is scheduled to be maintained before the sun goes down.

That added level of control makes slab sensors very powerful and advantageous when working with radiant floor heating. Once you have used them on one of your applications I predict that you will never go without again.

They become even more powerful when used for radiant cooling. Look for more on this topic in an upcoming issue. <> Mike Miller is a system controls specialist with experience in the manufacturing, distribution and contracting sectors of the industry.

City Multi Water-Source VRF System

MITSUBISHI ELE CTRI C

PRESENTED BY

Mitsubishi Electric’s City Multi System has been the leader in VRF technology for over 20 years. Many professionals have applauded the systems’ excellent performance in energy efficiencies, design flexibility, comfort control and total installed costs savings, in both new-builds and retrofit applications.

City Multi VRF system connects the variable speed condensing unit to the multiple indoor units using only 2 refrigerant pipes and eliminates the significant energy loss in the ducting system. While most HVAC systems operate at 40 to 80% of system capacity which result in frequent cycling, City Multi precisely controls the amount of refrigerant that flows to each indoor unit and thus operates in high part-load efficiencies with better dehumidification.

Energy Efficiencies City Multi water-source recovers heat energy from cooling zones to provide heating for other areas, between indoor units via refrigerant circuit and between systems via water circuit. This Double Heat Recovery feature as well as it being Geothermal-Ready allows City Multi water-source to provide excellent heating and cooling performance in all climates.

Design Flexibility The compact water-source condensing unit and the extensively long system total pipe length allow the City Multi system to be installed on practically any floor or location and fit seamlessly into any building design, rather than compromising the design around the system.

Comfort Control City Multi VRF system provides individual, personalized comfort and temperature control with simultaneous heating and cooling all year long. Each indoor unit can be switched between heating and cooling and the capacity is dynamically adjusted throughout the day to meet the changing zone load.

Total Installed Costs Savings City Multi water-source employs only 2 small refrigerant pipes and has a wide selection of compact indoor units in many different styles. The system eliminates ductwork, reduces plenum height and the overall requirement on supply fan size and CFM rating, as well as minimizing the mechanical room for a significant savings realized in design, material, installation and commissioning time.

Flexible Combinations: ECOi VRF Systems allow multiple indoor unit connectivity providing up to 130% of the total capacity of the condensing unit. This provides for up to 17 indoor units connected to each condensing unit.

Inverter Control Compressor: All ECOi VRF systems utilize highly advanced inverter controlled compressor technology. By varying the rotational speed of the compressor, the inverter control can precisely match the amount of refrigerant being delivered to the needs of each zone. This intelligent approach helps realize excellent efficiencies during partial-load conditions providing a consistent room temperature regardless of any increases or decreases in heat load during the day.

Lower Running and Life Cycle Costs: ECOi VRF systems are amongst the most efficient VRF systems on the market, offering COPs in excess of 4.0 at full load conditions. A unique road map control routine and an improved defrost sequencing also reduces running costs.

Panasonic Inverter® Single Split and Multi Split Air Conditioners and Heat Pump Systems Panasonic Inverter air conditioners offer reduced energy consumption and improved cooling efficiency. The Panasonic Inverter system constantly adjusts compressor rotation speed to provide optimum performance at all times. This extremely precise operation enables quick cooling while reducing power consumption compared to conventional non-inverter units.

With SEER ratings of up to 21, many models are ENERGY STAR® qualified. And all the units use the more eco-friendly R410A refrigerant.

The heat-pump models also provide outstanding cold climate performance delivering stable and comfortable heating even at temperatures as low as -18C. These indoor units are available in a variety of options including: wall mounted, ceiling suspended/recessed, one way and four way cassettes and low/medium static ducted models.

Samsung Neo Forte Ductless Air Conditioning System Samsung is a world leader in ductless mini-split technology providing the highest level of quality and comfort for its consumers. The Neo Forte air conditioning system from Samsung has been designed to provide the ultimate in zone comfort and energy efficiency for residential applications.

The Neo Forte uses S-Inverter technology to lower energy consumption by up to 50%, when compared to a conventional air conditioner. The inverter technology allows consumers to reach the desired temperature faster so there’s less fluctuation and less motor run time.

Additionally, the Neo Forte utilizes a multi-step air purifying health care system which removes virtually all elements that are harmful to people by using various filters. Not only does the Neo Forte purify the air, but it delivers the perfect temperature. When the Neo Forte is first turned on, the system goes into maximum capacity to reach the set temperature. Once the desired temperature is reached, the system adjusts to offset any changes (more people in the room, less people in the room, windows open or closed). This means there will be less temperature fluctuation and will translate into more comfort for you.

The Neo Forte can cover a wide range of operating ambient temperatures.

This unit will operate from 5F to 115F. That’s a range of 110F. While enjoying the perfect temperature, you’ll also enjoy the extremely low noise level of the Neo Forte. The Neo Forte compressor operates at the lowest speed possible while maintaining your desired set temperature. Perfect for areas where duct work cannot reach such as a finished room over a garage, sunrooms, basements, or computer rooms. The Neo Forte's clean look blends into any room while functioning as an exceptional air conditioner. With its innovative features, the Neo Forte makes a great addition to any room.

A Sprinter can be configured for almost any kind of work.

or the numbers-oriented contractor who needs a lot of capacity in a work truck, the Sprinter cargo van from Mercedes-Benz is certainly a contender. In its largest configuration, it has as much as 600 cu. ft. of cargo space and up to 84.3 in. of interior height. Its cargo capacity ranges up to 5375 lbs. and the towing capability runs up to 7500 lbs. On top of that, the sliding side doors can open as wide as 51.2 in., allowing a forklift to place a pallet-load of gear inside.

These numbers are impressive, but can a luxury car marque like Mercedes-Benz really be committed to the work truck market and the needs of busy contractors? We had to opportunity to learn about the company’s van and truck capabilities and intentions on a recent trip to Germany to visit Mercedes-Benz headquarters in Stuttgart and its Sprinter manufacturing plant in Düsseldorf. The factory is the largest van plant in the Daimler AG group, with its 2800 employees producing about 75 per cent of

all Sprinters built. In Europe, the Sprinter is the best-selling van in its category.

It is a vast, highly automated facility. The multi-storey Düsseldorf plant produces the body shell of the Sprinter with the precision of plus/minus three tenths of a millimetre. Automatic measuring stations installed on every body shell line use laser measuring systems to check production tolerances, and reject any major deviations. For each Sprinter, production robots place more than 7000 spot welds and up to 175 stud welds.

We learned the company has been in the truck business – well, since the beginning. Taking credit for the first automobile, an 1886 Benz, it also claims rights to the first truck, an 1896 Daimler. Models of both are on display at the massive and impressive Mercedes-Benz Museum in Stuttgart.

Despite all the economic turmoil in Europe, it was quite obvious during our visit that Germany is an economic pow-

Sprinters come in three basic sizes yet there are more than a thousand configurations available.

erhouse. The streets everywhere are busy with people hustling to work and back, and they are also full of cargo vans of all shapes and sizes – a large number of them badged with the trademark three-pointed star of Mercedes-Benz.

There are Sprinters like we get in Canada, of course, in both short and long wheelbases, three body lengths and three roof heights. Also familiar on the roads there were Ford’s Transit Connect cargo vans. And then there are dozens of unfamiliar vans in all sorts of shapes and sizes, most of which will never be imported to North America, with a couple of exceptions.

The Sprinter, in fact, is leading the charge for a new type of medium-duty cargo van in North America. No longer are contractors faced with a choice of standard-style vans like the Ford E-Series, Chevrolet Express or GMC Savana. Ford of Canada has successfully brought from Europe the aforementioned Transit Connect, a compact, 135-cu. ft. cargo van, while Nissan Canada offers its new Sprinter-chaser, the NV, another contender in the medium-duty market. And in the next couple of years, we can expect to see a larger version of Ford’s Transit, along with a cargo van entry from Fiat that will be sold by Chrysler Canada (the company dropped its Dodge Ram Cargo Van a few years back so is not currently a player in this market). Both these new models are expected to arrive in 2013 as 2014 models.

The Sprinters we get in Canada are shipped fully assembled from the Düsseldorf factory. Interestingly, US versions of the Sprinter – badged as Freightliners – are fully built to spec at the factory, then torn down and the parts boxed up for shipment across the ocean. A reassembly

plant in Charleston, NC, puts them back together for sale in the US. Configuring a Sprinter is no walk in the park. Not counting paint finishes, there are around 1000 combinations of wheelbases, heights, weights and engine variants possible. Around 120 different colours are offered – including five different shades of white, believe it or not. However, Arctic White is the standard colour for about 60 per cent of production. With so many choices, it seems almost every Sprinter is a one-off. However, the choices for Canada are limited in that only one engine is offered, a 188-hp V6 turbodiesel producing 325 lb.-ft. of torque. It’s mated to a five-speed automatic transmission.

Mercedes-Benz Canada already claims about 12 per cent of the medium-duty van market here, says Miki Velemirovich, the company’s van manager. That is about 2500 units. The plan is to grow the market share in Canada to 20 per cent.

In the next couple of years, we will also likely see new entries in the compact cargo van market from MercedesBenz. In Europe, its Vito and Vario vans are quite popular and likely will be brought to Canada, we were told, though a firm date has not yet been established. Both come in various configurations, but most interesting is the all-new E-Cell Vito, a fully electric van that can run about 130 km on a charge.

Currently, all but four of the 53 Mercedes-Benz Canada dealers are selling Sprinters, though just 43 are able to service them (the shops must often be rebuilt to accommodate the enormous size and height of these vans).

hpacmag.com

Wide-opening side doors can accommodate pallet-sized loads.

However, shop visits could be infrequent. According to Velemirovich, the service interval for 2012 models has been extended to 20 000 km.

The next iteration of the Sprinter won’t be until the 2014 model year, when it’s expected the body will receive a “more aggressive” facelift, says Velemirovich.

He also anticipates that the new series will offer a four-cylinder twin-turbo diesel engine that is popular in Europe.

Over the next couple of years, we’ll see some significant changes in the cargo van market as the key players introduce new models and designs to satisfy the needs of contractors across the country. No matter what, though, it seems that the benchmark to meet has been set by the Sprinter. <> Bill Roebuck is a long-standing voting member of the Automobile Journalists Association of Canada.

On the production line in Düsseldorf, Germany, laser-measuring systems check the Sprinter’s production tolerances.

Home Intimation

I

PRESENTED BY

FO REMO ST INTERNATIO NAL

usually start most articles with some kind of historical perspective – a look back on the way things were in order to provide context for the ways things are now, or the way they will be soon. Most times, the changes are interesting but not particularly surprising. However, in researching this article on home automation I was gob smacked at the leap taken in terms of the magnitude of the change; and this is what motivated me to coin a new term for the integration of technology into our homes and home comfort systems, what I now call “Home Intimation.”

The historical perspective is simple – according to Statistics Canada, in 2009 there were 13 946 000 total units in the Housing Stock (number of dwellings) of Canada and 52.5 per cent of those were constructed before 1983; with 56.1 per cent of those being single detached homes.

All of those homes had at least one thermostat –and most of those were among the nearly 50 million mercury bulb thermostats sold since 1950. This technology has been replaced, but there are still a huge number of these in service. What is of interest here is that many of the new replacements for these will not come from the traditional sources, nor will they necessarily be supplied through traditional routes to market.

We are quickly moving to a new era in the production and distribution of comfort controls. One where the big three are no longer in control of supply and one where what most would consider industry outsiders are gaining ground. In the past I have been involved with many projects that included home automation, but most of them were high-end custom homes with high-end home automation systems, such as those from Crestron. The focus of these was often control and monitoring of the lighting, building access and security systems, as well as control of the audio-video components.

While these systems certainly incorporated comfort control, this was not the primary focus for most homeowners.

The reason for the move to this new era – a three-stage leap forward from Hardware (stand-alone, purpose-built single function controls) to Hardwire (controls that required through cabling to a proprietary controller and a dedicated Internet connection) to Hardly-there (controls that communicate in any number of ways without hardwiring – WiFi being the one most people are familiar with), a

leap that has become really meaningful and accessible in the last 12 months.

A few months ago, I watched a series of television ads from Rogers, one of Canada’s primary cable/Internet communications companies, introducing its Smart Home Monitoring system. What caught my attention was the inclusion of comfort control as part of this service and the fact that it was being offered by a cable company. In the case of the Rogers' system, the thermostat used is not supplied to them by one of the big three. They have contracted local HVAC firms where installation of the thermostat is required and cannot be handled by the homeowner.

I recently met Andy Plarina, president of Poulsen Heating in London, ON, and talked with him about home automation. Founded in 1991, Poulsen’s is a small-medium sized regional HVAC firm with six trucks on the road. Like many firms, they are expanding their business into emerging markets such as radiant heating, geothermal. As part of this growth, they now offer customers the AccuLink home automation system from American Standard. The thermostat in the system piggy-backs onto the home automation system offered by Schlage – a maker of security, access, locks and door hardware. While the system is new to Canada, it has generated lots of inquiries for Plarina.

Most interesting was the October 2011 announcement that the so-called “Fathers” of the iPod had formed a new company and developed a product completely outside of the consumer electronics industry; or had they? When they announced the launch of Nest and its first product, the Nest Thermostat, some from inside the big three, or

hpacmag.com

even from among the traditional HVAC distribution chain might have questioned this decision and perhaps did not considered it a threat to their long-term business.

I however think this demonstrates how the importance of new perspective can drive real change. In the case of Rogers, consider the Internet infrastructure, the size of its existing business base, the brand recognition and market presence – coupled with the technical skills of their field staff and the fact that these new systems are software based – and it makes perfect sense for a cable company to be adding the installation of a wireless thermostat to their product offering.

Or consider the founders of Nest, having vast experience from having worked at Apple Computers, whose consumer electronics perspective and no history in the HVAC industry allows them to escape the paradigms of traditional product design and distribution.

For the first time ever, consumers want to buy a thermostat based on its function AND form, it now has a cool factor. It now truly becomes a consumer product, purchased online or through consumer electronics stores.

The features available from many thermostats in this new generation of products include: • Self-learning and programming. Gone are the rigid structures of weekday or weekend programming, they determine optimal settings based on occupancy (internal motion sensor) and actual settings input by the user.

• Coupling ambient temperature readings and linked to Internet weather sources, they can determine the optimal temperature setting within the home on a continually changing basis.

In Canada, some or all of these products and/or systems may have limited availability. The Nest for example is currently only available in the U.S. However, like the coming of the first iPad, resistance is futile. I am sure it will come and I look forward to being a participant in the era of “Home Intimation.” I for one will be camped outside BestBuy waiting to drop my bucks on the table to become part of the Hardly-there wave of consumer home comfort users. <>

• Reading and integration of outdoor temperature, indoor ambient (can include multiple points) and relative (indoor) humidity (RH). Many ask about controls suited to radiant cooling – the inclusion of RH and the integration of outdoor and indoor temperatures make this much simpler and cheaper.

Halifax Residents Set For Solar

building bylaw practices to have things solar ready. We think it’s pretty feasible.”

Boyle said the idea for the project started about a yearand-a-half ago, while the municipality was installing solar thermal systems on some of its own buildings. He said the HRM was looking at the various rebates and incentives available to help the municipality pay for the systems and found the rebates very attractive. It also allowed the HRM to see what the challenges were for residents, including finding the right contracting options and learning about the financial rebates available and how to obtain them.

“The barriers were more than just financing,” he explained.

“We had to find a way to make this easy for residents.”

Boyle said Nova Scotia is already home to a fairly healthy solar thermal market, so it has not been particularly difficult to find good solar contractors.

“It’s a good place to look at solar hot water heating,” he said. “There were 200 installations done in all of Nova Scotia last year and 800 in total in Canada, so that shows per capita we’re actually quite thriving. [Solar City] is a whole different scale. We’re going to be doing more in one year than was done in all of Canada last year. It’s pretty ambitious.”

Boyle said the model for the Solar City Project could work in future renewable technologies, but HRM needs to prove this project is a success before branching out into other areas. He said if the solar thermal project ends up being a success, he could see the possibility of a solar PV program starting up in the future.

The Solar City Project is expected to begin installations in May 2012. <>

unny days are on the way for approximately 1000 Halifax-area homes this spring. The Halifax Regional Municipality (HRM) has implemented its Solar City Program, which will equip about 1000 homes with residential solar thermal water heating systems.

Julian Boyle, energy manager for HRM, said about half of the homes will be equipped with the equivalent of one solar panel, while the other half will have the equivalent of two solar panels. He said final costs are still being determined, but rough costs before rebates will be approximately $8000 for the two-panel system and $6000 for the one-panel system.

Boyle said there has been a great deal of public interest in the project from local residents.

“We had a lot of people come out to the public sessions,” he said. “We had 800 people sign up in the first day. We cut off the registration at about 1600 after the first month.”

The popularity for the project stems from high energy prices and a unique piece of legislation that allows HRM to pay for the financing and installation of the systems up front, and recoup the money by adding a surcharge onto residents’ tax bills over a span of up to 10 years.

Boyle said other provinces, including Ontario and B.C., are watching closely to see how the project unfolds. HRM is the first municipality to his knowledge that has the legislative authority to allow the municipality to loan money to its homeowners for an energy improvement.

“That way we have a very secure way of getting our money back,” he explained.

Boyle expects residents to recoup some of the money from various government rebates, whether they take the option of HRM financing or not. He said that approximately half of the residents participating in the project have opted to pay for the systems up front.

Although the project is being called a pilot program, Boyle said the HRM are hoping the Solar City Program will be around for the long haul.

“It’s very much our intention that this project continue year after year. We’re looking at changing some of our

AHRI Pleased With DOE ENERGY STAR Report The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) recently stated that it is happy with the results recently released by the U.S. Department of Energy, under the ENERGY STAR program, regarding the verification testing of appliances and tankless and storage water heaters.

According to the AHRI, the results showed that “all tests of the claimed efficiency levels for storage and tankless water heaters turned up not a single result that would require further action.”

AHRI president and CEO Stephen Yurek said the test results support his organization’s belief that its certification participants’ products are being rated appropriately and should not be the focus of “federal scrutiny.”

Tankless water heaters and storage water heaters had perfect results in the released report. No product category had more than 14 per cent requiring further action. www.ahrinet.org

Together Forever

The influence of building materials, furnishings, finishings and a creative solution involving HVAC and interior design. BY robert bean

P

art II of my presentation explaining why HVAC designers cannot operate in isolation from interior designers (see Part I, p.20, HPAC January/February 2012) will use Figure 1, the ASHRAE Design Graph for Sensible Heating and Cooling with Floor and Ceiling Panels.1 Some of you might look at this and think that the psychrometric chart looks like child's play next to this graph; but like the psychrometric chart, they are both simple to use once you know how to navigate around the various components.

So let me start out with the geography of the graph. There are essentially six segments, of which the designer needs to establish three through calculation; that being the flux (q, Figure 2), average unconditioned surface temperatures (AUST, Figure 3) and characteristic panel resistances (ru, Figure 5); the first two (q and AUST) drive the temperature difference between the floor and space (|tp -ta|, Figure 4) to emit or absorb the flux at design conditions; the latter (ru) along with flux (q) and the selection in tube spacing (M, Figure 6) drives the average design fluid temperature in the pipes (tw, Figure 7).

Your choice in fluid delta t (∆t) in the flow calculation2 establishes the return temperature (treturn =tw-(∆t/2)) and thus

the efficiency of the boiler, heat pump, solar system or chiller; and it establishes the upper end of the reset curve for programming your fluid controller (tsupply =tw+(∆t/2)). Obviously all of the factors above are not trivial, as all affect the capital and operating cost of the system, the quality of the indoor environment, efficacy of the surface temperature and integrity of the panel materials, which is (again) why radiant should never be treated as a science experiment.

Let’s look at each of the steps in using the design graph.

Step 1. Heating or Cooling Flux (q), Btuh•ft2(W/m2) (Figure 2) Flux in heating is the energy released from the floor through radiation and convection per unit area. In cooling, it is the energy absorbed from convection and radiation. At the end of Figure 2 Heating or Cooling Flux (q), Btuh•ft2(W/m2 )

the day the performance of a radiant-conditioned building is judged by its surface flux. High flux represents a bad building, while low flux represents a good building.

I have categorized flux into four regions, as shown in Table 1.

The short strokes are the higher the flux the hotter the temperatures in heating and the colder the temperatures in cooling. Hot temperatures in heating and cold temperatures in cooling destroy plant efficiency. If you have to operate an embedded pipe radiant system at temperatures typical of baseboards, fan/coils, panel radiators and free standing radiators, you have missed the entire point of using the floor, walls and ceilings for conditioning people and spaces. Low temperatures in heating and high temperatures in cooling are the end game for sustainability – full stop.

Step 2. Average Unconditioned Surface Temperatures (AUST), F(C) (Figure 3) Any surface that is cooler than the heating panel will draw energy out of that heating panel. Likewise, a cooling panel will draw energy out of any warmer surface. All of the unconditioned surfaces combined (those without pipes), represent the radiant cooling or heating load on the conditioned panel.

These unconditioned surfaces along with the conditioned surface represent the mean radiant temperature (MRT) cal-

culated as an area weighted average. The value of the MRT averaged out with the dry bulb temperature (tdb), represents the operative temperature (top = (MRT+tdb)/2) as described in ASHRAE Standard 55 – Thermal Environmental Conditions for Human Occupancy. The calculation of AUST and MRT is beyond the scope of this article, but for terrific buildings (0-10 Btuh•ft2 (0-31 W/m2)) the AUST can in some cases be assumed to be at or near space temperatures.

temperatures are regulated by ASHRAE Standard 55 Thermal Environmental Conditions for Human Occupancy based on health and comfort research. In heating 85F (29C) and cooling 66F (19C) are the accepted boundaries for occupants wearing normal footwear. For bare or stocking feet, refer to the 2009 ASHRAE Fundamental Handbook, Section 9.15, Warm or Cold Floors.

Step 4. Characteristic Panel Resistance (ru ), ft2•h•F/Btu (m2•K/W) (Figure 5) This is an intimate element of interior design and is where the meat and potatoes of radiant design take place. It is also the one that is taken for granted especially by the DIY crowd.

Radiant panels are on site fabricated heat exchangers and ultimately the operating temperatures of the fluid are a function of what is known as the fin efficiency of the panel; which is a function of the resistance of: the flooring layers; conductivities of the pipe and encasing materials; pipe surface area; fluid flow characteristics; and log mean temperature differences in the exchanger design. You may have seen some of the finite element analysis (FEA) John Siegenthaler and I have presented on radiant systems. FEA is an excellent way of modelling the heat exchanger to evaluate its efficiency and effectivenessi. The calculation procedure again is beyond the scope of this article but the procedures are in the 2008 ASHRAE HVAC Systems and Equipment Handbook, Section 6.2ii.

Step 5. Spacing (M), in(cm) (Figure 6) As noted above, spacing plays a significant role in the effectiveness and efficiency of the panel. It also has a major affect on the surface efficacy, that being the quality of the surface temperature of the panel. To this day it asFigure 8 Radiant Floor Heating examples, part 1, flux q=25 Btuh ft2, ru =0.2 floor characteristics, M=9-in. spacing, ta =70F space temperature, part II, ru = 2.5 floor characteristics

HPAC | March 2012

tounds me that individuals try to save money on jobs by reducing the amount of pipe when it has a major affect on operating costs and quality of the system – this despite PEX pipe being the least costly component in a radiant system.

When it comes to heat exchanger designs, pipe is good and the more the better. Since servicing pipe after it is installed is not on anyone's “bucket list,” put in the highest quality pipe you can find. Lots of good quality pipe equals low temperatures in heating and high temperatures in cooling, which adds up to the highest efficiency and good comfort.

Step 6. Average Fluid Temperature (tw), F (C) (Figure 7) Average Fluid Temperature is the “keep your eye on the fry” component. Remember it is the average – meaning it is not the supply or return, it is the in-between temperature. That is why they call it the average – go figure. The lower the average temperature in heating and higher in cooling the better. How does this happen? It happens with good buildings with conductive floors and lots of pipe. It is not any more complicated than that.

Here are two examples: Example, part 1 Radiant Floor Heating (Figure 8) 1. From the flux side of the graph, q = (25 Btuh•ft2)(79 W/m2), draw a horizontal line straight across.

2. Deduct the desired air space temperature (ta =70F) from, in this case a hypothetically calculated AUST of 68F for a result of (-2F) (1C), and draw a line straight down to where it intersects the horizontal flux line established in Step 1.

3. Running parallel with the sloped lines for heating, take the line down from the intersection to the boundary and read the differential (approximately 13F)(7C). For a space temp Figure 9 Radiant Floor Cooling, part 1= 12 Btuh ft2 flux, 0.2 floor characteristics, 9-in spacing, 77F space temp

hpacmag.com

of 70F(21C), the floor temp becomes 70F+13F=83F (28C), which is within ASHRAE Standard 55. For those familiar with heat transfer coefficients, you would get similar floor temperature results with: [(25 Btuh•ft2)/(2 Btuh•ft•F)]+70F=82.5F (28C).

4. Now select a pipe spacing (M) and do not be cheap – more is better! In this case we have selected 9"o.c.(23cm) 5. F rom the intersection of (in this example) a hypo­t heti­ cal calculated Characteristic Panel Resistance (ru) of 0.2 ft2•h•F/Btu (0.03 m2•K/W), representing conductive low VOC flooring, we take a line down to the 9"(23cm) spacing line.

6. At the above intersection, follow the sloped lines to the boundary and read the value of 25F(14C).

7. Add this value 25F(14C) to the space temperature of 70F(21C) for an average fluid temperature (tw) of 95F(35C).

8. For comparisons do the same with a Characteristic Panel Resistance of 2.5 ft2•h•F/Btu (0.5 m2•K/W) representing a less conductive floor and likely with more VOCs. Message: The difference between low VOC conductive flooring and less conductive higher VOC flooring is, in this case, the differences between average temperatures of 95F(35C) and 150F(66C) or a 55F(31C) spread. Now think about this…with the low VOC conductive flooring and a 20F (11C) delta t, the return temperature becomes 85F(29C); which puts you into the high 90s in boiler efficiency and above a COP 4 for a heat pump – whereas the more resistive flooring puts you out of the heat pump league and drops your boiler efficiency into the mid range regardless of its high efficiency capabilities. All of this is based on 9"(23cm) o.c. which means it could get worse if you decided to go cheap and use wider spacings.

On the plus side, if you do your job and convince the builder and client to improve the building enclosure to get that load down from 25(79W/m2) to 10(32 W/m2), you can get that return temp down to 75F(24C) and that does not get any better from an energy efficiency perspective. To put some magnitude around 75F(24C), that would be a nominal 20F(11C) cooler than your blood temp, ergo hot water heating is NOT! There is absolutely nothing hot about these temperatures – tepid yes, but hot no.

Example 2 Radiant Floor Cooling (Figure 9) In this example we are showing a higher performing building with a low flux (approximately 12 Btuh ft2) (38 W/m2), and again, a low VOC conductive flooring with the same 9" (23 cm) o.c. spacing. Using the same process except working towards the upper part of the graph for floor cooling, the average cooling water temperature becomes tw =ta-12F=77F-12F=65F with a return temperature of 62.5F (17C) (based on an hpacmag.com

aproximate 5F (2.8C) differential). Also make note that based on a space temperature of 77F, the required floor temperature for cooling is only a nominal 77(25C)-10F(6C)= 67F (19C) or approximately 4.5F (3C) above the return fluid temperature.

At an approximate surface temperature of 67F (19C) you would be within ASHRAE Standard 55 for floor temperature comfort. Controlling the space to 50 per cent RH and 77F dry bulb (i.e. delivering a lean mixture (hop =0.01476–hload) to the space from the ventilation system) addresses microbial concerns (virus bacteria, moulds), provides for both stability of hygroscopic materials (woods), and occupant respiratory and thermal comfort. It also makes the condensation on the radiant cooling panel a moot point.

The FINAL WORD The message in Part I regarding the use of the IA-Quest tool for source control over interior finishes is part and parcel of IAQ and CSA F326 and ASHRAE 62.1(.2). It is also in the domain of the interior designer. As you can see from using the ASHRAE design graph, flooring also plays a big role in system efficiency and comfort, as well as IAQ. HVAC and interior design are glued together no matter how you cut it. But here is the upside: clients like their interior designers. In fact, they like them more than they like their HVAC contractors (I know that hurts); and the typical client of an interior designer is female with an above average income. Working with interior design professionals is a no-brainer for the progressive HVAC business owner. <> Robert Bean, R.E.T., P.L.(Eng.), is a registered practitioner in building construction engineering technology (ASET) and a professional licensee in mechanical engineering (APEGGA).

The Benefits of Accepting Credit Cards for Your Business

C

hoosing the right merchant account provider can be a daunting task. With various product solutions, different processing fee structures and the large number of processing companies and resellers, making the best decision for your business is not always easy.

Accepting debit and credit cards is commonplace in todayâ&#x20AC;&#x2122;s business environment because of the tangible benefits that are provided to the company. It becomes even more critical if a competitor is processing transac136

tions with debit or credit cards because it may be enough to sway customers away from your business.

Aside from keeping up with your competition, processing card payments improves sales and customer convenience at the same time.

THE STARTUP The initial cost for a business setting up a merchant account is relatively inexpensive. It is important to note that processors do not get paid until the merchant does, so there are very few upfront costs to begin processing

credit cards. It will also alleviate most of your back-office work because the transactions are organized electronically, thus simplifying accounting practices. Card processing also provides your business with added security benefits.

With card payments, merchants will not have to chase after customers for bounced checks or unpaid invoices. The PCI Council, a coalition between MasterCard, Visa, Amex, Discover and JCB International, has developed strict fraud-prevention measures to improve data security. hpacmag.com

“It becomes even more critical if a competitor is processing transactions with debit or credit cards because it may be

”

enough to sway customers away from your business.

By being compliant, merchant liability is reduced in the event of fraud and your business’ level of trust increases in the eyes of current or potential customers.

HOW DOES it WORK? A payment processor acts as an intermediary between banks and merchants who process debit and credit card transactions. During a transaction, the payment processor will verify the card data by forwarding it to the issuing bank or card association (Visa, MasterCard, etc). The payment processor will also take measures to reduce fraud during each transaction through strict verification procedures.

A LOOK AT FEES The most important aspect of the payment processing contract is the associated fees related to processing debit and credit cards. Every fee – and an explanation of what the fee is related to – will be listed in the contract. Merchants who process credit cards must pay a merchant discount fee, which varies depending on the type of card used.

For example, whenever a customer makes a purchase with a Visa card, the merchant may pay up to three per cent to various intermediary parties.

These fees apply to credit cards, debit cards and prepaid cards. The following example explains how the fees are broken down.

Consider this scenario: a customer purchases $1000 worth of mechanical contracting services and uses their credit card to pay. From that $1000, the mechanical contractor may receive approximately $980. Of the remaining $20, approximately $17.50 would go to the bank issuing the credit card, which is also known as an interchange fee. The remaining $2.50 is split between the credit card company and payment processor at a ratio of 80 per cent and 20 per cent respectively.

HARDWARE OPTIONS There are many options available in terms of hardware to process credit cards. The most common types of terminals are wired terminals versus wireless terminals. Wired terminals connect to the Internet using a plug

WHAT YOU NEED TO KNOW ABOUT CONTRACTS

Financial contracts can be very intimidating for small and medium business owners. The language and size of the documents are rarely uncomplicated to read, but the reality is they are extremely important. Processing contracts hold all the necessary information in regards to security, issuing banks, fees, hardware and so on, that a merchant must know.

In order to begin the process of obtaining a merchant account, you need to ensure you have a checking account, a copy of a void check, web access (for real-time reporting), tax returns and clear return policy information.

Payment processors will look at your credit score and banking records to determine if the merchant account would be high risk. Since the majority of small- and medium-sized businesses have a personal guarantee on their business, their record will have an impact on the merchant account. hpacmag.com

and have limited mobility. Wireless terminals allow for added mobility by working via a Bluetooth base station, or via cellular data networks, much like a cellular phone.

Wireless terminals that run on a cellular data network allow mechanical contractors to process debit and credit cards directly at the point of sale. Instead of invoicing the client at a later date, you will be able to charge your client immediately and either put that money in the bank or put it back towards your business. This helps simplify the process in which you get paid and reduces the amount of accounts receivables your accountant will have to deal with at the end of the year.

With the rapid growth of the Internet, the mechanical contractor is able to transform his or her computers into a virtual terminal to process payments without having to lease any terminal hardware upfront. A customer does not have to physically swipe a credit card; the contractor enters credit card information manually to be processed over the Internet. This is a low-cost alternative for small contracting business owners who want to accept credit cards but have no need for point of sale hardware. <> Alexander Galasso is manager of social media with Pivotal Payments (www.pivotalpayments.com), a provider of merchant services such as credit and debit card processing, electronic check conversion, merchant cash-advance programs, loyalty/gift card programs, and terminal management solutions.
