Refrigerant news: New Blend

A new blend of R32, R125 and R134a from Honeywell has received the designation of R-407F from ASHRAE and has been rated A1, indicating it has a low toxicity and is non flammable. It is seen as a viable replacement for R22 in medium- and low- temperature applications, particularly in supermarkets, requiring just a change of lubricant. However, its GWP is about 1600.
