The new successor to R410A?
The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) has given Honeywell’s new stationary air conditioning refrigerant R466A (also known as Solstice N41) the official designation A1 – non-toxic and non-flammable. The classification could be a key factor for manufacturers deciding which refrigerant to use in their systems in the medium-term. As a result of […]

Daikin launches R32 chillers
Daikin has introduced a new generation of air-cooled scroll chillers with R32 refrigerant to the Australian market. The new EWAT-B units offer a path away from R410A in the chiller market. In Australia, where the HFC phase-down is well under way, R32 has already become the de facto replacement for R410A in the split-system market […]

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 […]

Mitsubishi Electric launches ‘quietest ever’ system
Mitsubishi Electric has launched a new split system boasting quiet operation and dual barrier coating. The MSZ-AP models use R32 refrigerant and range from 2.5–7.8kW, making them suitable for cooling and heating most homes. Mitsubishi Electric says that thanks to new technology, the units are ultra-quiet during the day and even quieter at night. Users […]

Focus on flammable refrigerants
The HFC phase-down has seen increasing use of refrigerants with lower GWP but higher flammability such as R290 (propane) and R32. In turn, this has raised major concerns about the safe use of these gases. According to the Heads of Workplace Safety Authorities (HWSA), recent workplace fire incidents involving flammable refrigerant gases have “directly contributed […]

Official training now available for A2/A2L refrigerants
Training for A2/A2L mildly flammable refrigerants has been officially endorsed by the Victorian Registration and Qualification Authority (VRQA). This unit of competency can now be utilised across the nation. Kevin O’Shea, Chairperson of the Australian Refrigeration Council (ARC) says it’s a big win for technician safety. “Up until now, there were no training competencies endorsed […]

Honeywell announces “breakthrough” non-flammable AC refrigerant
Honeywell has announced a new non-flammable refrigerant called Solstice N41 for stationary air conditioning systems that it says could replace R410A, and could also potentially be a rival for R32. The HFC phase-down has prompted the search for alternatives to high global warming potential (GWP) gases such as R410A. At present, many original equipment manufacturers […]
