Abstract
The primary approach industry has taken to fill the void resulting from the elimination of the most important CFC's (i.e., CFC-11 and CFC-12) has been to develop other single component refrigerants (i.e., HCFC-123 and HFC-134a) which have very low or zero ozone depletion potential. These alternatives were attractive mostly because they had similar pressure-temperature property profiles relative to that which they were replacing and, thus, required minimal machinery design changes for adoption.
