With a European, and soon worldwide, phase down on HFCs, high GWP refrigerants like R410A are under pressure. While R32 has been taken up as the interim alternative for R410A in smaller splits, its flammability makes it unsuitable for use in VRF systems. Despite Honeywell’s secrecy, ...
This phase-out was created by the Clean Air Act of 2010. Limited supplies of R22 are available, and some of it is recycled/reclaimed R22. Should I convert my AC system to R410A or should I buy a new HVAC system? Conversion is possible but not recommended. The conversion is a time-...
With a worldwide phase-down of high GWP HFC refrigerants now appearing to be inevitable, the main air conditioning refrigerant R410A, with its GWP of 2088, is coming under increasing pressure. The Japanese air conditioning manufacturers, lead by Daikin, have so far backed R32, a single comp...

R410A has been widely used in residential and commercial heat pumps due to the phase-out of R22 under the Montreal protocol [15]. However, the Kyoto protocol and F-gas regulation in Europe requires the use of low GWP refrigerants. R32 is considered one of the most suitable substitutes for...
