HCFC HCFC (Hydrochlorofluorocarbons) Hydrochlorofluorocarbons are organic compounds that are similar to CFCs but less destructive to ozone. HCFCs consist of carbon, hydrogen, chlorine and fluorine. They are used as replacements for CFCs, but are to be phased out by the year 2020, as specified by the Montreal Protocol, when they are expected to be completely replaced by hydrofluorocarbons (HFCs).
Fluorine and chlorine containing hydrocarbons
Hydrochlorofluorocarbons. A chemical compound with molecules that contain one, two or three carbon atoms and at least one atom each of hydrogen, chlorine and fluorine. HCFCs have a lower ODP than CFCs. The hydrogen makes them less stable and therefore less damaging to the ozone layer than CFCs. They are considered acceptable substitutes for CFCs for a transitional period. HCFC production and importation will be phased out by 2020 for most HCFCs, and by 2030 for HCFC-123. For further information about HCFC, see the HCFC table and the NOAA Climate Monitoring and Diagnostics Laboratory site.
Hydro Chlorofluorocarbons
are compounds containing carbon, hydrogen, chlorine and fluorine. They have shorter atmospheric lifetimes than CFCs and deliver less reactive chlorine to the stratosphere where the "ozone layer" is found.
a fluorocarbon that is replacing chlorofluorocarbon as a refrigerant and propellant in aerosol cans; considered to be somewhat less destructive to the atmosphere
Hydrochlorofluorocarbon, a chemical compound used in aerosol cans.
hydrochlorofluorocarbon - a refrigerant, typically R22 - see refrigerants
A class of refrigerants. Generally refers to Halogenated Chlorofluorocarbon family of refrigerants.
Hydro-chlorofluorocarbon: ozone depleting substance used as a refrigerant in mechanical refrigeration systems; to be phased out under the Montreal Protocol
Hydrochlorofluorocarbon, a member of FC family containing hydrogen, chlorine, fluorine and carbon.
Hydrochlorfluorocarbons or hydrogenated chlorofluorocarbons. Because they are less destructive to ozone, they are a substitute for CFCs (1/10th the environmental damage of CFC) although less efficient as refrigerants and sometimes quite toxic.
