It is the most abundant HFC in the atmosphere. R-410A is a mixture of two other HFC refrigerants, R-125 and R-32, and offers greater cooling properties than older HCFC refrigerants when they are subjected to higher pressures. very environmentally desirable. Without refrigerant, or if it were to run too low, the compressor would get dangerously hot and fail. Fluoro R404a Gas is over 99.9 % pure and is one of the most preferred R404a gases in the country. the use of AC systems powered by CO2 instead. they have an accident though. HCFCs are being phased out, but most older AC units use them, along with new “dry-charge” units that avoid the Montreal Protocol restrictions because the refrigerants are added by the buyer.
