hydrochlorofluorocarbon

[¦hī·drə¦klȯr·ə′flu̇r·ə‚kär·bən]
(organic chemistry)
A compound composed of hydrogen, chlorine, fluorine, and carbon atoms. Also known as HCFC.

Hydrochlorofluorocarbon

(HCFC)
Compound commonly used as a refrigerant in compression-cycle mechanical equipment, such as refrigerators, air-conditioners, and heat pumps, or as a blowing agent to produce foam insulation. It is an alternative refrigerant type that has reduced ozone-depleting effects.
