[Editor's note: This article is the first in a series focusing on refrigerants and refrigerant blends. This month's article will concentrate on the HCFC-22 air conditioning replacement refrigerant blend HFC-410A.]
HFC-410A, or better known as R-410A, is a refrigerant blend of R-32 and R-125. Both R-32 and R-125 are hydrofluorocarbons (HFCs). HFCs are void of chlorine, thus have a zero ozone depletion potential (ODP). HFCs do have a global warming potential (GWP). Both ODP and GWP will be covered in a later article.
Refrigerant blends consisting of two refrigerants are referred to as binary blends. R-410A is a longterm, high-efficiency replacement refrigerant for R-22. R-410A has a very small evaporator temperature of glide 0.2°F, and has negligible fractional potential. R-410A is replacing R-22...
