Abstract

The present invention provides refrigerant blends which are replacements for chlorodifluoromethane (HCFC-22). The present blends have refrigeration characteristics which are similar to HCFC-22. The blends comprise from about 10 to about 90 weight percent of a first component selected from the group consisting of 1,1,1-trifluoroethane, difluoromethane, propane, and mixture thereof; from about 1 to about 50 weight percent of a second component selected from the group consisting of hydroflu-orocarbon having 1 to 3 carbon atoms, fluorocarbon having 1 to 3 carbon atoms, inorganic compound, and mixtures thereof hav-ing a boiling point at atmospheric pressure in the range from about -90 degrees C to less than -50 degrees C; and from about 1 to about 50 weight percent of a third component which is hydrofluorocarbon having 1 to 3 carbon atoms, other than 1,1,1-trifluoroe-thane, having a boiling point at atmospheric pressure in the range from about -50 degrees C to about -10 degrees C. The refriger-ant compositions have a vapor pressure substantially equal to the vapor pressure of HCFC-22.
