Refrigerants And The Environment

Refrigerant-12 and related CFCs, Refrigerant-11 and Refrigerant-22, are currently the major compounds used in the cooling and insulation systems of home refrigeration units. It has been found, however, that CFCs are posing a major threat to the global environment through their role in the destruction of the ozone layer. A search has therefore begun for replacements, and some manufacturers of CFCs have already pledged to phase out these products by the end of the century.
