Which refrigerant is not HCFC?

Explanation:
HCFCs are chlorine-containing refrigerants used as transitional replacements for CFCs. They all include chlorine in their chemical makeup, which gives them some ozone depletion potential. The refrigerants that are HCFCs include those like R-22, R-123, and R-124. The one that is not HCFC is R-134a, which is a hydrofluorocarbon with no chlorine atoms, so it has essentially zero ozone depletion potential. That’s why it’s categorized separately from HCFCs, though it does have a high global warming potential and is also subject to phase-down efforts.
