Abstract:
The primary approach industry has taken to fill the void
resulting from the elimination of the most important
CFCs (i.e., R11 and R12) 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 profiles
relative to that which they were replacing and, thus,
required minimal machinery design changes for adoption.
