➲ Editorial

A GOOD KNOCK After an eventful 10 years, the 100th incarnation HVAC&R Nation has finally made its way off the printing press and found its way into your hands (or computer screen). In this day and age, print-based publications are quickly becoming an endangered species, and many well-established newsstand staples have had to cut their runs to cater to diminishing demand. Attention spans are shorter and things just don’t seem to stick around very long – so we think cracking 100 issues is a feat worth acknowledging. In cricketing terms, it’s a century on a deteriorating pitch, somewhere on the sub-continent, in 40°C heat – it has been an innings to remember. Back in 2007, AIRAH and founding editor, Neil Cox wanted to give the HVAC&R trade sector a publication of its own – something that hadn’t been done in Australia before. In many ways, the guys on the tools were the underacknowledged faction in an already unappreciated and “invisible” industry.

The industry has come a long way in the past 10 years, and the mag has evolved alongside it. As technology continues to advance, and the industry transitions to low-GWP refrigerants and lower emissions, we hope to keep the trade sector’s ear to the ground. Of course, the focus on industry skills and safety remains at the core of what we do. Like any century, we couldn’t have done this without a quality partner at the other end. Our advertisers, AIRAH members, support staff, previous editors, and most importantly – the readers – have made this mag what is it today. And to that, we’d like to raise our bat to you guys. The slog continues, though; the job isn’t done just yet. Time to resettle and bat through till stumps – this is going to be a long innings. Boon Mark Souphanh Editor

Today, HVAC&R Nation can hold its head high as Australia’s most popular HVAC&R magazine. A badge we’d like to wear for years to come.

A SAFE option

A change in the air

NHP has released the new SAFE-T SRCB, designed as a retrofit RCBO solution suitable for use in single-phase general light and power distribution boards.

Air Change has unveiled its new dehumidification product range, designed specifically for applications requiring precise humidity and temperature control.

In addition to being suited to NHP SAFE-T panel boards, two versions are available to suit Eaton and Heinemann panel boards.

“Humidity, whether generated by the introduction of outside air, infiltration, or the building use, can lead to unpleasant mould formation, condensation and uncomfortable internal conditions if not correctly controlled,” says the company. “Air Change has recognised these adverse effects and what they mean to the HVAC&R industry. As a result, the dehumidification range was designed to provide energyefficient solutions engineered to meet these applications.”

NHP says the range ensures quick replacement of MCBs without modification to the busbar chassis system.

“Now more than ever, it is critical to ensure your existing pane boards are installed with residual-current circuit breakers that are compliant with AS/NZ standards,” says NHP.

Combining patented heat-exchange technology with new refrigeration controls and research, the range is headlined by the ACDHUM Low Dewpoint Dehumidifier, which uses an alternative refrigerant system that is designed to consume less power than a typical desiccant system.

The SAFE-T SRCB was developed with this in mind and is suited to retrofits into existing boards. SRCB units also offer overload, short-circuit and earth leakage protection in single-pole units. 02

“With many organisations already in the process of upgrading panel boards, now is the perfect time upgrade your existing circuit breaker,” says NHP. “For peace of mind safety that ensures the protection of staff, the public, and assets, choose the NHP SAFE-T SRCB.”

New-age gauge

Yellow Jacket says its new vacuum gauge is the first unit of its kind capable of positive pressure up to 31bar (450psi) without damage. The unit is built into a small ballistic plastic case, with added features such as multiple units of measure, an electronic screen that can be read in direct sunlight, and a settable audible alarm when the target is reached.

The PX3 series heavy-duty pressure transducers convert pressure into an analogue electrical signal. It has brass housing and can support multiple configurations, with the aim of helping end-users minimise implementation and production costs. “Our new line of PX3 pressure transducers feature low-current consumption to help reduce system energy costs, while also enhancing product life when used in battery-driven systems,” says the company’s business president Graham Robinson.

The new line expands the sensors’ pressure range from 1 bar to 50 bar (15 psi to 700 psi). In addition, the PX3 series also offers freeze-thaw resistance to frost, which is commonly found in refrigeration systems.

They are now available from selected wholesalers. For more information, contact the Yellow Jacket Australian representative Sky Refrigeration at www.skyrefrig.com n

The new line of pressure transducers are also compatible with many next-generation, low global-warming-potential (GWP) refrigerants, including Honeywell’s Solstice N40.

Strong recovery

New imperial offering

The new LD-920 detector for H2N2 tracer gas is designed with an extremely high sensitivity of 5ppm. The unit also meets the criteria for tracer gas supplied to article 6, Paragraph 3 of EU Directive 2006/40/EU.

For more information, go to www.imperialtools.com.au n

“Traditionally 3-pipe systems utilise single-port branch selector units as they have various advantages including less refrigerant charge, no drainage requirement, and the ability to operate multiple indoor units off a single branch selector unit to serve a large common zone,” says Daikin. The multi-port branch selector units can connect up to 16 indoor units off one branch selector, this potentially reduces the number of connections and on-site installation costs.

Imperial Tools Australia now supplies US-made tube working tools and refrigeration service equipment, including a new range of leak detectors for the HVAC&R service industry.

According to Daikin, the waste heat from indoor units operating in cooling are recovered and redirected to those requiring heating. This results in superior system energyefficiency gains compared to conventional HVAC systems. The VRV IV Heat Recovery offers both multi-port and singleport branch selector units. For better efficiency on long pipe runs, the company has designed the VRV to operate in a 3-pipe configuration.

Low-current cost saver

Honeywell has expanded its line of pressure monitoring sensors, which are designed to minimise the total cost of pressure management for HVAC&R systems.

Hydroheat’s adaptive addition

The BAXI Duo-Tec GA wall-hung range is a new class of boiler combining commercial features in a residential compatible package. 06

The Baxi Duo-Tec GA is designed to use gas-adaptive control, which automatically calibrates and adjusts to the type of gas supply for reduced consumption.

Toolshed The company says that gas-condensing technology extracts and reuses heat from burnt gases to deliver a rated efficiency of 97 per cent, making the Duo-Tec GA range one of the greenest and most efficient domestic boilers on the Australian market.

The ECOSTAR LHV5E and LHV7E are an air-cooled series of condensing units from Bitzer.

In addition, BAXI have added the GA+ upgrade to the package, which is designed for Hi-Flow pump capacity.

The units are designed to be energy efficient, low noise, and reliable, while being easy to install and maintain.

The boilers also feature the “think” internal operating system, frontal access for easy servicing, and complete soundproofing.

“Both series of condensing units have an improved mini-channel condenser, which means they need less refrigerant charge, while at the same time being more efficient than their predecessors,” says Bitzer.

Models range from 12kW to 40kW for indoor and outdoor use. For more information, go to www.hydroheat.com.au n

Exciting expansion

The new ECOSTAR condensing units also have electronically commutated fans and active PFC monitoring, which allows users to adjust the speed and power of the fans and of the integrated ECOLINE VARISPEED compressor.

“In this way, it is possible to operate with optimised energy requirements, with a low number of switching cycles,” says Bitzer. “The new condensing units also boast a reliably long useful life and low maintenance requirements. Devices can be quickly installed on-site thanks to the control electronics being factory-wired, making them immediately ready-to-operate.”

Sporlan Division of Parker Hannifin Corporation has expanded its line-up of connectors, tools, and ZoomLock compatible components for more HVAC&R uses. Parker braze-free connectors are available in straight couplings, long radius 90-degree elbows, tees, reducing couplings, slip couplings and cap connectors from 1/4” to 1-3/8”. Access fittings (extended couplings with Schrader Valve) and Y fittings are also joining the line-up. The additions aim to assist technicians by reducing the time they spend brazing these fittings.

High-performance for high temperatures

Armaflex Solar UT is a flexible closed-cell pipe insulation for solar hot-water systems.

Designed to make systems more convenient to install, there are ZoomLock-compatible components including ODM x ODM ball valves, Catch-All® filter-driers, See-All® sight glasses, and solenoid valves.

Specifically designed and tested for the flow and return lines of solar hot-water systems, Armaflex Solar UT is intended for high temperature applications (up to 150˚C) and long-term outdoor exposure.

For more information, go to www.sporlanonline.com n

An ECOSTAR is born

The insulation is available in 15mm thickness to provide an R-value of 0.6 (AS/NZS 4859.1) to reduce heat-loss from pipes, helping to potentially reduce energy demands.

Sensor sensation

The XZR500 from Michell Instruments is designed to determine the optimum amount of air needed for combustion, ensuring the fuel is used efficiently.

Made from EPDM material, it is designed to withstand the excessive temperatures throughout the year, which can help save energy and effectively reduce the hazard of very hot pipes. For a complete and professional installation, Armaflex Solar UT tape is available for high temperature applications.

The unit monitors the exhaust gas for excess oxygen, allowing the users to keep conditions close to stoichiometric levels.

For more information, go to www.armacell.com.a n

Featuring Michell’s Zirconium Oxide Oxygen sensor, the XZR500 has a metallic sealed reference (MSRS) designed to give long-term reliability. The combination of this type of sensor, placed in an isothermal oven within the analyser (not the probe), aims to negates the effects of varying, high temperatures, as well as the corrosive nature of the gas. “This also reduces time spent on maintenance,” says Michell Instruments. “If a sensor needs replacement, this can be done within minutes without interrupting the process. The MSRS provides its own reference meaning a single calibration gas can be used.”

The XZR500 also has a control unit which can be placed at ground-level, and a sensor head close-coupled to the stack for easier of installation and quicker response. According to the company, combustion efficiency for boilers and industrial waste incinerators are typical uses for the XZR500.

➲ Global Update KENYA

A FRESH IDEA Kenyan IT graduate John Mbindyo is helping local farmers and vendors reduce food wastage by building low-tech cooling units that use solar energy. The solar-powered, walk-in cold boxes offer farmers and retailers reliable cooling and storage facilities for their perishable food items. Mbindyo says that the inspiration to develop this resourceful technology came from his interactions with local grocery vendors who endured huge losses due to lack of proper refrigeration solutions for their products Installed in markets and farms within the reach of farmers and vendors, the units offer cold room temperatures of as low as 5°C. n

USA

INNOVATIVE HEAT SHEET A thin, artificially structured "metamaterial" that can cool objects without water or an external energy source has been created by engineers at the University of Colorado. The glass-polymer hybrid material works to lower the temperature of the surface beneath it via "passive radiative cooling", meaning it vents the object's heat through thermal radiation while rejecting incoming solar energy. The film is only 50 micrometres thick, just slightly thicker than aluminium foil. Researchers say it can be easily and economically manufactured by the roll for large-scale residential and commercial applications, including cooling buildings and power plants, and being applied directly as a coating for solar panels. n

JAPAN

HANTENS BRING THE HEAT Coats with battery-powered heaters were one of the big hits in Japan this past northern winter. Produced by Osaka-based Kumagai Electric, the “hanten” jackets make use of a length of micro carbon fibre running from the nape of the neck down to the small of the back. The fibre functions as a heater, drawing power from an included battery pack, which is switched on by pressing a button located on the front of the garment. The heater can be adjusted to one of three strengths, and battery life is reported to be up to seven hours. Tradtionally, hantens are a thick, quilted half coat that have been a staple in Japanese homes for generations. However, the modern heated versions are marketed with a more stylish retro vibe. n

JORDAN

COMPANIES COP IT The European Commission has fined six car air conditioning and engine cooling suppliers €155 million (AU$216 million) for taking part in one or more of four cartels in the European Economic Area. The suppliers coordinated prices or markets and exchanged sensitive information on the supply of climate control components and engine cooling components to certain car manufacturers. The companies involved were from Germany Japan, and France. All companies involved acknowledged their involvement in the cartels and agreed to settle the case. The Commission cooperated with antitrust authorities in Japan and the US during the investigation. n

R22 PAIN IN SPAIN

The Jordanian government has announced itself as the first developing country to utilise solar energy for the cooling and heating of buildings.

A former company owner in Spain has been sentenced to six months in prison after offering the HCFC refrigerant R22 for sale on the internet.

Under a 4.3-million-euro program, thermal cooling technology will be introduced to Jordan and surrounding regions.

The United Nations Environment Programme (UNEP) says the individual was also fined and prohibited from involvement in any commercial activity related to refrigeration or air conditioning for six years.

Four sites in Jordan are already equipped with solar systems. The country’s environment minister Yaseen Khayyat says that power consumption at these sites had dropped by 40 per cent following the installation the solar technology. “The state-of-the-art systems will not only reduce power consumption and encourage the use of renewable energy resources, but will also serve as a reference for researchers and experts in the field,” says Khayvat. n

The case was one of a number that came to light during SEPRONA investigations back in 2012 and 2013 into possible illegal trade in ozone-depleting substances, focusing on refrigerants offered for sale on the internet. Further Spanish investigations in 2014 uncovered around 20 advertisements f or R22 on different websites. n

However, r range as Sean Mc Gowan disc is more to a overed, there secondary re frigerant tha n meets the eye. As we detailed in last month’s issue of HVAC&R Nation, concerns about the rate of emissions and impact on global warming by hydrofluorocarbons (HFCs) has brought about a phase-down that will begin in Australia next year. It follows the previous phase-out of ozone-depleting chlorofluorocarbons (CFCs) and the current phase-out of hydrochlorofluorocarbons (HCFCs). Such moves have already pushed the HVAC&R industry to adopt alternatives. With natural refrigerants such

as ammonia and CO2 becoming more commonplace, fourth-generation refrigerants and HFOs are also becoming part of the future mix. However, these alternatives present a challenge to the industry. “We are moving to a future where refrigerants will have more challenges associated with them, including higher levels of toxicity and flammability,”

10 | HVAC&R Nation | www.airah.org.au/nation | April 2017

says A-Gas Australia’s commercial manager Graeme Dewerson, M.AIRAH. To manage the extra risk, there is a trend towards centralising the primary plant while adopting a heat transfer fluid in a secondary loop to remove heat from the process. “As refrigerants come with higher pressures, more toxicity and more flammability, keeping the system away from people is going to become more important,” says Dewerson. We need only look at the use of ammonia, which continues to be a mainstay of process cooling, and the role secondary loops play in delivering energy-efficient cooling while isolating the dangers posed by fluid to the plantroom. Although the secondary heat-transfer fluid (or secondary refrigerant) is one of the least expensive components of the system, its role is critical to the overall refrigeration system operating both effectively and efficiently. So, as the industry looks to reduce the energy consumption of associated pumps and heat

Feature energy required to circulate glycol around the system, especially in low temperature (LT) applications.

KINEMATIC VISCOSITY OF SECONDARY HEAT TRANSFER FLUIDS

“When you cool fluids they become more viscous, and the greater the kinetic viscosity the greater the power consumption required to pump it around the system,” Dewerson says. A secondary refrigerant loop using glycol at -15°C will require around 35 per cent glycol to 65 per cent water, but a system operating at -40°C will require a much larger ratio of glycol to water, thereby increasing viscosity. The low temperature will further increase viscosity, resulting in a further increase in pump energy use.

“It’s at these temperatures that you might want to move away from a glycol solution and consider other options like salt-based solutions,” Dewerson says.

LOWER VISCOSITY SALT SOLUTION Designed to be both non-toxic and food safe, salt-based solutions (or brines) are the next evolution in secondary heat-transfer liquids.

A solution designed in Europe combines two organic salts (potassium formate and potassium acetate). Tests show that it achieves greater heat-transfer properties than glycol and has much lower viscosity, particularly at low temperature. This means smaller pumps and heat exchangers can be used on the secondary loop system, delivering significant reductions in capital cost and energy consumption. And, if the idea of a salt-based solution sounds like a recipe for a corrosive disaster, don’t fear. “The salts used in this product are not as aggressive as your standard sea salt, so they are easier to inhibit,” says Dewerson. “And they’re food safe, as is the chemical inhibitor used to protect the system from corrosion.”

The inhibitor creates a localised, temporary thin protective layer across the metal surface that allows for good heat transfer while protecting against corrosion. This makes it safe to use with copper, bronze, brass (dezincification resistant), steel, stainless steel, cast iron and plastic pipes such as ABS and PE.

exchangers, heat-transfer fluids are receiving much greater attention. And not surprisingly, there are a number of options available.

GOOD OL’ GLYCOL

Though more expensive than glycol, Dewerson says the energy efficiency benefits of using a salt-based solution in the secondary loop are significant, and provide a return on the extra investment. This is particularly so when used in large systems such as those serving process-cooling applications.

The two forms of glycol most commonly used in Australia are monoethylene glycol (MEG) and monopropylene glycol (MPG). MEG is less expensive than MPG but is toxic on ingestion and cannot be used in processes where it may come into contact with food.

Glycol has long been the standard go-to product for secondary refrigeration loops.

MPG offers the HVAC&R industry the benefit of being non-toxic, so it can be used in all applications, making it the product of choice by many.

While in its raw form, glycol can cause metals to corrode. The addition of a chemical inhibitor means this can be prevented, making it suitable for use as a heat-transfer liquid.

According to Dewerson, MPG for heat-transfer applications is designed to be food-safe (in the event of a leak) as both the glycol and corrosion inhibitor are non-toxic.

“Glycol has become a very successful product,” says Dewerson. “You can put it into a system and leave it for many years, and you won’t get a single trace of rust so long as there’s enough inhibitor in there.”

“In food, beverage and dairy applications, using MPG just makes sense,” he says.

“With an industry looking to find energy-efficiency savings wherever it can,” says Dewerson, “a salt-based solution really does tick all the boxes.” n

electronic devices that contain small amounts of rare earth metals including platinum, gold and silver. "Tokyo 2020 Olympic and Paralympic medals will be made out of people's thoughts and appreciation for avoiding waste," says gymnast and one of Japan’s greatest ever Olympians Kohei Uchimura. "I think there is an important message in this for future generations." Collection boxes for the old electronics will be placed in offices and telecommunication stores around Japan starting this month. The committee is confident that around eight tonnes of metal will be collected, which will contribute to two tonnes of usable material. Should the committee hit this benchmark, approximately 5,000 medals will be produced for the 2020 Olympic and Paralympic games.

Medal winners at the 2020 Tokyo Olympic Games will receive one-of-a-kind sustainable souvenirs. The Tokyo 2020 Olympics are still over three years away, but the Japanese government is already implementing unique ways to get its citizens

involved in the spirit of the games – and is doing so with sustainability in mind. Confronted with scarcity of natural resources, Olympic organisers had the dilemma of creating the hundreds of medals needed to reward the Games’ athletes. In response, the Tokyo Summer Olympic Games has announced a "green" initiative under which discarded electronics parts will be recycled to create materials for the Olympics, including all the medals. The Olympic committee is calling on all Japanese citizens to donate old smartphones or obsolete

The initiative looks to provide a tangible and sustainable way for citizens to get involved with the Olympics, but also helps satisfies sustainability criteria set up by the International Olympic Committee (IOC). And, athletes from other countries are already giving the idea the green thumbs up. “Thanks to the Tokyo 2020 Medal Project, not only do the athletes inspire with their stories, but each medal itself has a story of its own,” says two-time US Olympic gold medallist Ashton Eaton. “The best part is that each citizen has a chance to contribute to the story, to raise awareness about a sustainable future and to make a unique contribution. And, most excitingly, they have a chance to be part of the Olympic journey.” n

AIR FILTERS

– CONSIDERATIONS IN MAINTAINING AIR QUALITY AND ENERGY EFFICIENCY

To some, the humble air filter is commonly misunderstood as merely “a thing in the duct that blocks airflow”. While that is somewhat true, the primary function of the air filter is nobler – to protect the people and facility components that are downstream of it. If the filter blocks or is allowed to collect too much particulate material – excessive amounts of fan energy will be consumed and the amount of air being pulled through the filter will reduce – affecting the health and comfort of the occupied space. In short – air filters are a critical component in maintaining the air quality and energy efficiency of a facility.

FILTER FUNCTIONS Air filters used for “pre-filtration” have two main functions; • Improve indoor air quality • Protect downstream equipment Generally, these pre-filters are designed and manufactured to be cost-effective and be energy efficient. Protecting downstream components such as secondary air filters and cooling coils allows for better long-term performance and further energy savings.

Flat-panel filter.

When it is doing its job, a filter becomes clogged with particulates over time. So, these pre-filters must be replaced to maintain air-flow for efficiency and performance of the system.

indoor air quality. They have a significantly greater surface area and dust holding capacity than flat panel-type filters due to the pleated air-filtration media.

In HVAC systems, it is considered more cost effective (and environmentally safe) to replace and dispose of these pre-filters, rather than clean them on-site (washable air filters).

The higher the number of pleats, the larger the working surface area the filter has. Ultimately, the higher useful surface area maximises the filtration capability of the filter, and reduces its resistance to air-flow. Metal V-form and cardboard disposable are the most common type of pleated-panel filters.

Washable filters still remain most relevant for kitchen exhaust hoods and some “mist eliminator” applications in seaside areas

COMMON FILTER TYPES Flat panel filters are the most basic type of air filter, whereby a flat panel of air filtration media is enclosed within a metal frame. They serve to prevent very large particles “rocks” from entering the system and are typically made to order. Pleated panel filters are really the start of effective particle removal to generate higher

Standard metal V-form filter.

Metal V-form filters. These rugged filters have pleated-air filtration media inserted into a channelled metal frame. A number of methods are typically used to create the pleats within the air-filtration media, including galvanised mesh adhered to one side of the media and zig-zagged steel cage supports within the frame channel. Some suppliers offer a premium version metal V-form, whereby the pleated filter media is “potted” or bonded (e.g. hot-melt sealed) into the metal channel frame to eliminate potential contaminant bypass.

In general, V-form filters offer respectable dust holding, moderate performance and a useful life. The more advanced forms are very resistant to by-pass, so work at the rated value for all their working lifetime. Metal V-form filters are typically available in standard sizes, with custom sizes made to order. Cardboard disposable filters are constructed from pleated air-filtration media bonded to a cardboard frame (typically moisture-resistant beverage-grade cardboard).

WHAT ARE THE CHARACTERISTICS OF A QUALITY DISPOSABLE CARDBOARD PLEATED AIR FILTER? Surface area

Cardboard disposable filter.

Bag Filters have excellent dust-holding capacities and reasonable pressure resistance. They are bulky, and take a significant duct length to house them. Some design versions are tricky to install and remove, and they are available in a vast number of configurations, ratings and sizes. The most common types of bag filters include: Peaked bag filter – Four peak (full size) or two peak (half size) deep bed-style bag filter mounted to a metal outer frame and inner basket assembly.

Pleated air filters have a greater surface area and dust holding capacity, as compared to flat panel-type filters. The higher the number of pleats, the larger the surface area it can contain. Ultimately, the higher surface area maximises the filtration capability of the pleated air filter and reduces the energy consumption.

Filter media quality Synthetic filter media are resistant to moisture build-up and ideal for preventing the proliferation of mould and mildew. Pleated air filters must be able to sustain a high-efficiency performance, with a relatively low-pressure drop, to be effective in air filtration, so premium quality media should be used.

Quality cardboard frame Strong, durable cardboard frames should withstand the force of the air stream and support the filter media. Beverage board-grade cardboards are resilient against water infiltration that can lead to premature structural deterioration. A stable housing module helps to achieve a longer service life. Poorly designed filters, can collapse prematurely, creating major problems for downstream equipment.

Quality media bonding Pleated air filters should be safely and tightly bonded to the cardboard frame to prevent air bypass (where contaminants can escape through the small gaps on the sides of the filters). Four-peak bag (Full size). 16 | HVAC&R Nation | www.airah.org.au/nation | April 2017

The combination of all of these design considerations helps to achieve an appropriate airflow static and load capacity that maximises energy efficiency, change out periods of disposable filters, and loading.

What is the impact of selecting quality disposable cardboard pleated air filters over cheaper alternatives? There are many cheap cardboard pleated air filters available in the market today, which use inferior quality components and construction methods. These cheaper alternatives often provide poorer performance, risk product deterioration and mould (a known health risk), and have a shorter service life that requires more frequent change-outs. The long-term costs associated with inferior quality product include increased energy consumption, more frequent product replacement, increased load on more expensive downstream filters, and potential contamination of expensive equipment or components. There is also potential for poorer air quality or health risks associated with product deterioration and mould. Buying sub-par disposable air filters might be a tempting idea because of lower upfront charges. However, it does not lower energy costs or guarantee longer service life, high-quality performance, protection of expensive components or better air quality.

HVAC&R Skills Worskhop More advanced filters, which are used in special applications (HEPA filters), are carefully constructed from “silica-based” materials and binders to form a “paper-like” surface for removal of very fine particles. Any of these specialty filters require special handling methods and processes.

Nominal filter dimensions can vary by manufacturer, so when dealing with replacement filters, it is essential to know actual filter dimensions and the quantity required before you re-order.

COMBINATION FRAMES Many commercial HVAC applications require staged filter sequencing, such as a combination frame assembly. This typically includes a cardboard disposable pre-filter and pocketed bag or multi-pocket bag filter installed within a metal holding frame. Corner clips or P-clips are commonly used to secure the filters in place.

Accepted filter performance rating systems are EN779:2012 (G1 to F9), ASHRAE 52.2 (MERV 1 to 16) and the new and controversial ISO16890. Based on the successful removal of airborne particles by size, these ratings provide a relative measure of filter effectiveness; whereby lower-rated filters remove larger-sized particles and higher rated filters remove smaller-sized particles. Higher-rated filters will remove more airborne particles. However, this is almost always at the cost of energy and more frequent filter changes. Similarly, lower-rated filters will impact air quality, duct cleanliness, heat-exchanger performance, and in some cases – safety.

PULLOUT

Inspection of your current filters will reveal their rating, and you should replace these filters with (at minimum) a comparable-rated filter. With large installations, it is worth checking the original filter specifications to confirm the right filters are still installed.

Combination frame assembly (Cardboard disposable pleated filter and multi-pocket bag filter secured to 100mm holding frame with corner clips).

Filter sequencing works like a set of sieves – the first stage (cardboard disposable) collecting larger particles and the second stage (bag filter) collecting finer particles. Special applications that require ultra-clean air quality, such as clean-rooms, would require a third stage (HEPA).

AIR FILTRATION MEDIA HVAC air filtration media is available in cotton-polyester blends or pure synthetic blends. Filter media manufactured from 100 per cent synthetic fibres are recommended for use within HVAC applications, as they are resistant to moisture build-up and will prevent the proliferation of mould and mildew. Quality air filtration media will ideally sustain a high-efficiency performance, with a relatively low-pressure drop, to be effective at air filtration.

FILTER LIFETIME In a well-designed system, static pressure is a recognised measurement to indicate appropriate filter change-out times.

FILTER SIZE AND RATINGS

Multi-pocket bag (Full size).

As mentioned before, if the filter looks “dirty” with collected dust, it’s far beyond the cost-effective change-out point.

Over time, it is worth consulting with a knowledgeable and trustworthy filter manufacturer, to see if higher performance filters can result in higher IAQ and lower energy costs. Often by making a change to a modestly more expensive filter that provides lower pressure drops and larger dust holding capacities, you can actually reduce total costs of your clean air equation.

FILTER CAPACITY While nominal dust-holding capacities obtained from controlled laboratory testing are useful when comparing similar filters within a manufactures range, comparisons between different filters or manufacturers can be misleading. This is due to differences in test conditions, dust ranges and other factors. Similarly, real-world dust, temperature, humidity and other contaminations are difficult to directly relate to this laboratory test data. As such, you should seek advice from suppliers with reputable technical knowledge and experience. Ultimately, with replacement filters, actual historic data will be your best guide. Finally, all filters have a finite capacity and benefit from staged filter sequencing i.e. pre-filters followed by higher efficiency final filters. Staged filter sequencing allows inexpensive filters to be sacrificed to maximise the life of the more valuable final filter.

For example, if the static pressure across a G4 filter was measured above 175Pa, it is demanding to be changed. While this filter is still providing good air quality improvements, the excess energy used in airflow would cost more than the filter is worth to change. The appropriate static change-out value for filters change significantly depending on the airflow rate, type of filter, grade of filter, hours of use per day and the dust concentration of the air being filtered. A common value if 125–150Pa is often seen as appropriate. Magnehelic gauges or other sensor methods connected to the BMS are worthwhile additions to a filter housing to give an indication on filter performance. In general, it’s always better to change filters early, rather than late.

ENERGY EFFICIENCY With steady increases in energy costs and priorities to decrease energy usage for greener buildings, effective air filtration is an increasingly critical component of the energy efficient facility. Accurate tracking of static pressure via a software or manual system will be a significant component in the overall energy assessment. With older buildings, an overall review of the filter-types and ratings, fan settings and system construction will reveal valuable opportunities for energy savings that would be comparable to LED-lighting conversions.

FINAL THOUGHTS Buying decisions should start with obtaining the right filter, and then conducting service changes at the appropriate time. Supplier considerations should include stock availability, breadth of range, credible support, warranty and overall cost. Similarly, local and knowledgeable support is an important factor, when changes or upgrades are being considered. The humble filter is often a forgotten part of the facility, but the people and equipment that it protects are critically important. So, when did you last check your filters? n

PROGRESSIVE PIZZA Instead of building a pizza by toppings, customers choose prebuilt combinations from the menu. This allows the algorithm to guess correctly more often.

Imagine having a robot-constructed pizza, baked in the delivery van, arrive at your front door in minutes. For residences in Silicon Valley, this is now quickly becoming the norm. Everyone wants a slice of the automation revolution, and it appears that pizza delivery is the latest food staple to get involved. Based in the US tech hub Silicon Valley, Zume Pizza not only uses robots to prepare its orders, but also implements special oven-equipped vans to bake the pizzas so they’re fresh and piping hot upon arrival at customer’s door. When Zume opens for business at each morning, an algorithm has already predicted what pizza orders should be pre-prepared. According to the company’s creators, pizza customers are incredibly habitual,

Once orders are placed, they go through a factory-like assembly line. Humans toss the dough and place the veggies, but sauce squirts from an automated overhead tube, and the finished pizza is loaded into an oven with a super-intelligent robot arm.

This robotic arm named “Bruno” is a key part of Zume Pizza’s kitchen.

often ordering the same toppings every week. However, Zume pushes its predictive model further by designing a menu that eliminates the specificity of those predictions. "There are so many creative endeavours that are human-led and always will be. But there are other things we do that are perfect for robots," says co-founder Julia Collins. "Our technology is not designed for a full-scale customisation of pizza. We try to approach it by having a very well-curated menu."

After a quick par-cook, the pizzas are loaded onto one of four over-equipped trucks. The delivery driver is then guided to each location by GPS, while the final bake happens automatically, beginning when the truck is just four minutes away from the destination – this ensures freshly baked pizzas every time. Upon arrival, the driver ejects the pizza from the oven and places it in the truck's pneumatic, self-cleaning slicer. "Right now, humans pull it out of the oven [and] into the cutter, but we’re working on a robotic arm to do that," says Collins. Zume currently delivers approximately 250–300 pizzas a day. However, its creators have ambitions to produce "10-times" more than that by the end of 2017, expanding the business to the California Bay Area through 2018, before moving onto Los Angeles. n

➲ AIRAH Q&A

BRIDGING THE GAP

Part two

Portfolio manager at Perth’s South Metropolitan TAFE in Perth, Graham Boyle, F.AIRAH, has nearly 50 years in the industry under his belt, including 36 years in the training system. Amid the much-talked-about skills shortage plaguing the industry, HVAC&R Nation caught up with the industry veteran to pick his brain on the heated debate. In part II, Boyle discusses the divisive topic of licensing and how the industry should approach it. HVAC&R Nation: The feature mentioned that half of advertising RAC employers didn’t manage to fill their vacancies, while 40 per cent advised that the vacancies attracted no suitable applicants. Surely, these kinds of statistics are calls for concern.

Should a newly trained and qualified technician have the experience to fully apply all the skills learned during an apprenticeship? According to Graham Boyle, F.AIRAH, it is rare.

GB: The issue about the suitability of applicants from the research in the article appears to revolve around the ability of technicians to fault-find generally and have knowledge of manufacturers’ units. We need to be realistic here. It would be rare for a newly trained and qualified technician to have the experience to fully apply all the skills learned during an apprenticeship. With any new job, there is a period of familiarisation required as the new employee comes to terms with the expectations and tasks required. Applying current knowledge in new situations is a skill that develops with experience.

HVAC&R Nation: Do we need to implement a new occupational licensing scheme to fix the problem? HVAC&R Nation: Do you think qualified technicians are getting the right training? Graham Boyle: In the recent “Mind the Gap” feature in last October’s HVAC&R Nation, there was a noticeable concern expressed about the skills of qualified technicians. This issue is as old as the apprenticeship system. Apprentices are trained through a mix of “on the job” and “off the job” training. Although the apprenticeship contract has a time allocated to it – around four years – we are supposed to be in a “competency-based training system”, so time served can vary. This is understandable as the people coming into apprenticeships come with a range of skills and experience, and a variety of ages. I had one student who had already completed an electrical apprenticeship and a Certificate IV in Instrumentation, and was adding R&AC to his CV. Obviously, someone that is so highly skilled is not going to need a further four years of training. In Australia, we have a national competency-based training system, but that doesn’t guarantee that graduates will all have the same skills. Much will depend on this diverse industry that they trained in. Some may have worked in supermarket refrigeration or transport refrigeration, industrial refrigeration, commercial or domestic air conditioning – it would be uncommon for new graduates to have gained

experience in all these areas. So, depending upon the requirements of the new position, their skills and experience may be lacking.

GB: There is a view in some sectors that a new occupational license will be a panacea to repair all the ills, both real and perceived. I don’t believe this to be the case:

LICENCE LIMITATIONS Earlier this year, the Australian Refrigeration Council (ARC) has communicated with all restricted “split system installation” licence holders Australia-wide to remind them of the limitations of the entitlements of their licence, and the work they can and can’t do. The ARC is critical that restricted heat pump, split systems – installation and decommissioning licence holders do not work beyond the scope of works permitted on the restricted licence as they are not competent to do so. “The ARCTick licence scheme is a qualifications-based scheme. That’s how licence holders prove their competency to perform services to the ARC,” says ARC CEO Glenn Evans. “A person with a ‘split system installation’ licence has provided a Certificate II level qualification and the Ozone regulations

20 | HVAC&R Nation | www.airah.org.au/nation | April 2017

state this is the requirement to demonstrate their abilities to perform installations of split systems up to 18Kw. They have not demonstrated their ability to perform repairs, servicing or maintenance. That’s the domain of Certificate III level licence holders - and rightly so. They have demonstrated their abilities to perform those services – and that’s what their licence entitles them to do.” It is an offence to handle refrigeration and air conditioning equipment without an appropriate refrigerant handling licence and a penalty of up to $1,800 may apply. Working outside the scope of a licence could also result in the cancellation or suspension of a licence. “Summer is the business-end of the year for our sector so let’s make it a safe, legal and prosperous one for industry and consumers alike,” says Evans.

AIRAH Q&A Even if there is an appetite for a new national licence then the issue is – what are we licensing? We already have a nationally accredited qualification that comes under a national regulator (ASQA) We must also ask, who is the regulator? What is the safety or health issue that will require licensing? Which government department will regulate the industry? What skills need to be demonstrated to apply for the licence and how are they to be measured? Who is going to pay for the new system? Probably the user, I’m guessing.

Graham Boyle, F.AIRAH

In most jurisdictions, we already have two licences, an Australian Refrigeration Council (ARC) licence and some form of state-based restricted electrical licence. While I have only worked in Western Australia, I know that to apply for an “open” ARC licence you must have a nationally recognised qualification. And to apply for a restricted R&AC electrical licence, the regulator will require an applicant to provide their Certificate III and a copy of their trade papers. There seems to be a lack of clarity as to what another licence will achieve that cannot be achieved by the licences that we already have. If there are people that are working beyond the scope of their current licences, then they risk prosecution. But if they are already working beyond the scope of their current licence, what guarantee is there that they will comply with a new licence?

from industry parties, then maybe there would be an incentive for individuals to further their skills. You can read part one of our Q&A with Graham Boyle, F.AIRAH in the March issue of HVAC&R Nation, which is available online at www.airah.org.au/nation n

HVAC&R Nation: If changes to licensing aren’t the answer – what do you suggest we do? GB: Maybe the solution is to develop a skill-based post-trade system of courses or “skill sets” that are nationally recognised by employers and industry as adding value to the skills of a qualified tradesperson. Much of this training is available and subsidised by the government. However, if specific training is developed for specific needs, it may be better to offer as “short courses”, which are not publicly funded such as vendor training from manufacturers. Currently, we offer BMS skills, commissioning skills, CO2 training, HC training and BIM. There are also some TAFE award courses available, Certificate IV and Diploma that are nationally recognised and can be linked to high-level traineeships, but they wither and die because of a lack of interest. Much of this training is available and can sit on a technician’s CV, but if we had national agreement

CRACKIN’ THE TON After 10 years in the game, the Nation has finally brought up its century! Here, we take a look back at the evolution of Australia’s most popular HVAC&R magazine over the years.

2007 Launching in June 2007, we wanted to give the HVAC&R trade sector a mag of their own – something that made fridgies feel part of a community. Our first-ever cover story “Putting life into old fridges” exemplified this, covering the Phoenix Fridge Project in Melbourne’s northern suburbs. The project was undertaken all in the name of the community and the environment, working with unwanted fridges and improving their energy efficiency by up to 20 per cent through simple repairs and retrofits.

2008–2011 Quickly building its profile, 2008–2011 was a formative period for HVAC&R Nation. Making its way to more wholesalers, TAFEs and AIRAH members alike, the mag’s profile grew, as did the scope of the feature topics. From automotive HVAC, to Dubai’s Burj Khalifa tower – the mag well-and-truly covered more than just the “Nation”.

22 | HVAC&R Nation | www.airah.org.au/nation | April 2017

2012–2014 Adopting a modern new look, the mag’s aesthetic changes coincided with a transitional period in the industry. An increased demand for air conditioning in developing countries, coupled with the push for low global-warming-potential refrigerants worldwide hastened the move towards mildly flammable refrigerants – most notably the introduction of R32.

2015–2016 While it was a period of great change for AIRAH, HVAC&R Nation remained steadfast in its approach, and continued to provide the industry’s trade sector with useful and practical content.

2017 and beyond Celebrating its 10th anniversary, HVAC&R Nation is still the most widely read, useful and engaging publication for those who work on the tools. Looking slicker than ever, the magazine is now also available in its entirety online at www.airah.org.au/Nation

COUNCIL’S NEW CHAIR

Shayne La Combre has been elected as the new Chair of the World Plumbing Council (WPC) for the 2016–2019 term. The election was held during the recent WPC Triennial Conference in Cape Town, South Africa. “During the next three years, the WPC will dedicate its efforts in promoting the integral role plumbing plays in societal health and wellbeing, amenity of the built environment and environmental protection,” says La Combre. Previously the CEO of the Plumbing Industry Climate Action Centre (PICAC), La Combre aims to support projects and initiatives to promote education and training within the industry during his tenure. “I am excited to accept this challenge and I do not take lightly the importance of this role and the opportunities it can bring to the industry,” he says. “In my term as Chair, together with the newly appointed executive Board, I plan on further strengthening existing partnerships by actively seeking involvement from key organisations and working to develop new relationships.” n

ARA SINGS TO A NEW TUENA

The Australian Refrigeration Association (ARA) has announced the resignation of its president Tim Edwards, who leaves his post due to health reasons. After a five-year tenure, Edwards’ role will be taken over by Ian Tuena, M.AIRAH, of CA Group Services. “The ARA Board and I thank Tim for the contribution he made in establishing the ARA and causing the HVAC&R industry to consider the value of natural refrigerant based technology,” says Tuena. "As a key stakeholder, we assure you that the ARA Board is committed to increasing the effectiveness of the ARA." According to Tuena, there is enormous potential for improvement in HVAC&R services in Australia.

"We understand that we need for far greater participation by industry stakeholders in delivering the cost savings and emissions reduction made possible by natural-refrigerant-based technology,” he says." Australia has the ability and need to lead this opportunity in the national interest . . . and it needs to happen now." For more information, go to www.ausref.org.au n

YOUNG WORKER SAFETY A PRIORITY

SafeWork NSW is encouraging businesses to make it a safe year as thousands of young workers enter workplaces for the first time, making the need to focus on safety even greater. According to SafeWork NSW, young workers under the age of 25 accounted for 16 per cent of all injuries in NSW workplaces during 2013/14, with seven fatalities and 15,715 injuries. Executive director of SafeWork NSW Peter Dunphy says complacency among experienced workers and over-enthusiasm by young workers were major factors in many workplace incidents at this time of year. “The return to work period at the end of the school holidays requires extra caution on the part of businesses and workers,” says Dunphy. “Concentration and complacency are issues experienced workers must be conscious of. Young workers entering the workforce for the first time are keen to impress which can lead to them to take risks that their more experienced colleagues wouldn’t take. This increases the risk of injury at this time of year and is why we’re encouraging businesses to reinforce the need for safety to be the number one priority.” Dunphy highlights inductions, toolbox talks or tips for safety that emphasise safe work methods as ways to reinforce business’ safety culture. “These are particularly important for workers who have had changes to their job or workplace over the break,” he says.

NOT-SO-COOL SCHOOLS

In response to the summer heat, a primary school teacher started a Change.org campaign petitioning Queensland education minister Kate Jones to expand the Cooler Schools Zone to cover parts of Brisbane and Ipswich. Maria Santiago says she was sick enduring the heat in Ipswich classrooms, after having to send students home due to extreme heat. The Cooler School Zone dictates which areas in Queensland are considered hot and humid enough to receive school-wide state government-funded air conditioning. "This year so far, some classrooms have reached temperatures over 40 degrees,” says Santiago. “Most days, thermometers are climbing to the mid to high 30s and some of these classrooms are poorly ventilated.

for the well-being of students and staff in schools outside the Cooler School Zones that have been suffering the heat each summer. There is no funding support from the state. If our schools want air conditioning they or the P&Cs have to fund them and some of them can't afford it." The petition quickly gained support, reaching over 2000 signatures. n

NEW TRAINING PROGRAM FROM FANTECH

Fantech is offering a new Intelligent Ventilation Training Program, a one-day training program focused on intelligent ventilation solutions. It is available to contractors, consultants and developers, and covers carpark ventilation, low-pressure VAV diffusion design and EC motor technology. Fantech Intelligent ventilation product manager Peter Henry, M.AIRAH, says the program comes at a time of great technological advancement in the industry. “We believe that intelligent ventilation can reduce costs,” he says. “Therefore, we want to share our knowledge of these smart technologies through the new training program… Training programs are also particularly valuable for newcomers to the industry as they provide a great opportunity for participants to network and meet new people.”

Created by industry associations the Air Conditioning and Mechanical Contractors Association (AMCA) and the Air Conditioning and Refrigeration Equipment Manufacturers Association of Australia (AREMA), the program is supported by the Air Conditioning Refrigeration and Building Services (ARBS) Education and Research Foundation. The 2017 scholarship builds off the success of last year’s inaugural program, where five students and their teachers from TAFE colleges across Australia participated in a two-week residential course at the RCCC. The aim of the Industry Educational Trade Scholarship is to increase the quality of trained tradespeople in the HVAC&R industry and reward students who have demonstrated aptitude to successfully complete their trade training.

A Brisbane school now has 10 brand-new air conditioners installed after it successfully raffled-off tickets to popstar Adele’s concert at the Gabba stadium.

According to Fantech, attendees will learn new techniques and take away practical tools that will allow them to design intelligent ventilation solutions for their own customers. Real-world examples and design demonstrations will be used during the program.

Despite having just two weeks to sell the raffle tickets, Adele fans contributed $7,500 to the school off the back of the Parents and Citizens' (P&C) Association raffle.

This new training program complements the established Engineer’s Training Program, which Fantech has been running since 2008. Both programs

“YES, MINISTER” The federal Minister for Industry, Innovation and Science looks forward to AIRAH collaboration. AIRAH has received a letter from the Minister for Industry, Innovation and Science, Arthur Sinodinos AO, acknowledging the Institute’s contribution to the HVAC&R industry.

looking forward to the Senator’s tenure as Minister for Industry, Innovation and Science, and hope we can work collaboratively towards the greater good of the industry.”

Following a cabinet reshuffle in mid-January, Senator Arthur Sinodinos took the reins on the federal government’s Industry, Innovation and Science portfolios, taking over from Greg Hunt, now Minister for Health and for Sport.

Swings, strokes and smiles at the WOA golf training event.

WA GETS INTO THE SWING The Women of AIRAH group recently held its inaugural golf training event in WA.

A keen group of 14 budding golfers attended the first-ever Women of AIRAH golf training event at Maylands Peninsula Golf Course in Perth. Hosted by AIRAH’s WA division, the group received a 1.5-hour coaching session from two of the club professionals. The event concluded with some refreshments and networking.

“A lot of the group were swinging the club and putting much better by the end of the session,” says WA membership services officer Alison Mattes. “Overall, it was a great day and we look forward to putting on the event again. It was also nice to see a few male participants attend, despite it being a WOA event.” The event was sponsored by Systemaire.
