Definitions for "Hydrochlorofluorocarbons"
Organic compounds like CFCs but with extra hydrogen atoms, and a lower ozone-destroying potential. They have similar properties to CFCs and are being used as temporary substitutes for them.
Composed of carbon (C), chlorine (Cl) and fluorine (F), with at least one hydrogen (H) atom. The first generation of CFC substitutes; they decompose in the troposphere and have little chance of reaching the stratosphere
A family of chemicals related to CFCs which contains hydrogen, chlorine, fluorine and carbon atoms. HCFCs are partly halogenated and have much lower ODP than the CFCs. Examples of HCFC refrigerants are HCFC-22 (CHClF2) and HCFC-123 (CHCl2CF3).
