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.
