R-22 is classified as which refrigerant type?

Explanation:
R-22 is an HCFC, a hydrochlorofluorocarbon. Its chemical formula includes chlorine along with hydrogen, carbon, and fluorine, which places it in the HCFC family. This distinguishes it from CFCs (which contain chlorine and fluorine but no hydrogen) and from HFCs (which contain hydrogen and fluorine but no chlorine). It’s not a natural refrigerant either, since natural options are things like ammonia or CO2. HCFCs have ozone depletion potential lower than CFCs but are still ozone-depleting and are being phased out in many systems in favor of alternatives.
