Winding road ahead for mobile air conditioning
While the HVAC&R sector tends to focus on the built environment, mobile air conditioning represents a significant portion of Australia’s refrigerant bank – and poses serious challenges as we look to phase down HFCs. The most recent Cold Hard Facts report indicates that mobile air conditioning comprises more than 20 per cent of Australia’s total […]
The most significant change in NCC 2022?
Although the 2022 edition of the National Construction Code is still at draft stage, one of the biggest changes is already confirmed: a new look with improved useability. This will apply across all three volumes of the NCC: Volume 1 (Class 2 to 9 buildings); Volume 2 (Class 1 and 10 buildings); and Volume 3 […]
Kirby Apprentice Fund celebrates second birthday
The Kirby Apprentice Fund is celebrating its second anniversary with the announcement of training scholarships to promote the use of natural refrigerants. The Naturals Training Scholarships will be available to fourth-year apprentices registered in the Kirby Apprentice Fund who want to further their trade knowledge with an understanding of natural refrigerants. The scholarship will facilitate […]
Dwyer releases new photohelic pressure switch/gauge
Dwyer Instruments has released the Series AT-A3000, an ATEX/IECEx-approved photohelic pressure switch/gauge. “The flameproof-approved Series AT-A3000 ATEX/IECEx-approved photohelic pressure switch/gauge functions as versatile, highly repeatable pressure switch combined with a precise pressure gauge employing the time-proven Magnehelic gauge design,” says Dwyer. The device measures and controls positive, negative or differential pressures of air and compatible […]
Autonomous drones to sniff out refrigerant leaks
Researchers at the Delft University of Technology in the Netherlands have developed a swarm of tiny drones that can autonomously detect and localise gas sources in cluttered indoor environments. One of the key challenges the researchers faced was the minimal processing capacity of the drones. They overcame this by using bio-inspired navigation and search strategies. […]
New controls proposed for HFCs and HFOs
Five European countries have proposed new legislation that could see HFCs and HFOs classed as per- and polyfluoroalkyl substances (PFAS) – and covered by tighter regulations. PFAS are a group of synthetic chemicals that are very persistent in the environment and the human body. They do not break down, and can accumulate over time. They […]
COVID-19 restrictions clarified for HVAC&R workers
Since new COVID-19 restrictions came into force in New South Wales, those employed in the HVAC&R industry have been seeking clarity on whether they can continue working. Although considered by many as an essential service, HVAC&R is not explicitly referred to in the rules. The NSW government guidance for critical repairs, maintenance and cleaning states […]
Updates to incentives for refrigerated cabinets
The Department of Environment, Land, Water and Planning (DELWP) is updating the Victorian Energy Upgrades (VEU) program for refrigerated cabinets. Refrigerated cabinets are designed to store and display chilled and/or frozen food items, and are typically used in retail stores such as supermarkets, petrol stations, liquor outlets and smaller food and beverage vendors. The VEU […]
Locked-down industry gets free access to online learning
In response to the COVID-19 restrictions that have halted construction work in New South Wales, Standards Australia is offering temporary free access to a compulsory e-learning module. “The recent COVID restrictions have forced New South Wales into lockdown again, and for the first time, have put the brakes on the construction industry, impacting almost 250,000 […]
Sixth Element Australia offers ARC Earthrings
The ARC Earthring is a shaft earthing ring designed to protect electric motor bearings from bearing fluting generated by modern-day variable speed drive systems. “Damaging voltages are induced on the shafts of AC and DC motors controlled by variable frequency drives (VFD),” says Sixth Element Australia. “The extremely high on/off switching speeds of the pulse […]
