Improving refrigerant recovery from split systems
A new report from Refrigerant Reclaim Australia (RRA) has highlighted the concerning volume of refrigerant lost when split systems reach end of life in Australia. It estimates that each year, hundreds of tonnes of refrigerant are not being reclaimed. Factoring in the global warming potential of the gases, this could equate to more than a […]

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 […]

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 […]
