Graham Wright, legislation specialist for Daikin UK, which is launching small AC units with R32 into the UK next year, has reintereated that the refrigerant’s mild flammability need hold no fear for installers.
Speaking at F-Gas Question Time, Mr Wright said: “The tools are becoming available and the manufacturers will be ensuring everyone is trained and educated before anything goes on the market over here . One million R32 units are already working in Japan, with Panasonic, Mitusbishi and Hitachi all producing equipment, as well as Daikin.”
Among the advantages, he said, were the ability to use units with smaller footprints and a smaller refrigerant charge than their R410A predecessors. He said: “We should remember that R410A is 50 per cent R32 so it is pretty straightforward in use.” He added that R32 offered the the opportunity to use a refrigerant which doesn’t suffer the problems of glide. He demonstrated how difficult it was to ignite the gas and noted that R32’s burning speed was actually slower than walking pace.
