CFC and HCFC refrigerants contribute to the breakdown of the ozone layer and the greenhouse effect. CFC is an abbreviation of chlorofluorocarbon; HFC is an abbreviation of Hydrochlorofluorocarbon. They describe the molecules’ atom content.
International and national restrictions surround CFC an HCFC due to the environmental effects they cause. In many EU countries, their usage as refrigerants in new installations is prohibited. The refrigerants are however found in a large number of existing installations.
R12, R22, and R502 are the most commonly used CFC and HCFC refrigerants.
ODP (Ozone Depletion Potential) is a number that indicates the refrigerant’s effect on the ozone layer. R12 is used as index 1.0, and comparisons are made as a result.
GWP (Global Warming Potential) is a number that indicates the refrigerant’s effect on the greenhouse effect. CO2 is used as index 1.0, and comparisons are made as a result.
