hydrochlorofluorocarbon Definition

Hydrochlorofluorocarbons (HCFCs) are a class of organic compounds used primarily as refrigerants, solvents, and foaming agents. They contain hydrogen, chlorine, fluorine, and possibly other elements, and they were designed as a replacement for chlorofluorocarbons (CFCs) because of the former's lower ozone depletion potential. However, they are still potent greenhouse gases and contribute to global warming.
