ARC releases free ‘tech packs’ for R32
The Australian Refrigeration Council (ARC) and the Department of Agriculture, Water and the Environment have created free “tech-packs” on R32 refrigerant for licensed technicians and authorised businesses. The packs contain information on refrigerant characteristics and properties, equipment requirements, safety, relationship to R410A, and more. They also include refrigerant safety stickers to help technicians identify the […]

Report finds ‘disjointed’ laws on flammable refrigerants
A new report commissioned by Refrigerants Australia has mapped out the laws that govern the use of flammable refrigerants in this country. It also highlights key themes and gaps within the regulatory landscape. The report, written by Bronwyn Weir and Krista Weymouth, reveals a complicated patchwork of regulations. There is no one set of laws […]

Flammable charge limits on the move again
Charge sizes for flammable refrigerants in HVAC&R equipment are changing with a proposal to raise international limits for room air conditioners, and the adoption of a new standard in Australia for refrigeration appliances. An International Electrotechnical Commission (IEC) working group has released a proposal to update safety standard IEC 60335-2-40. This would allow larger amounts […]

How flammable is ‘mildly flammable’?
A multi-million-dollar research project led by AHRI, with support from ASHRAE, the US Department of Energy and the California Air Resources Board, has comprehensively tested refrigerants to answer questions around their flammability. In Australia, the topic continues to provoke debate, and understandably so. Because of the HFC phase-down, previously common non-flammable A1 refrigerants are giving way […]

MHIAA announces training on A2/A2L refrigerants
Mitsubishi Heavy Industries Air-Conditioners Australian (MHIAA) and Superior Training Centre are running a course on A2/A2L refrigerants in Sydney on June 7. Pushed along by the HFC phase-down, manufacturers have been rapidly switching their split system air conditioning units from R410a (with a GWP of 2,088) to R32 (GWP 675). According to the Expert Group […]
