Alternative Refrigerants for Building Air Conditioning
Abstract
The majority of building air conditioning has
traditionally been achieved with vapor compression
technology using CFC-I I or HCFC-22 as refrigerant
fluids. CFC-11 is being successfully replaced by
HCFC-123 (retrofit or new equipment) or by HFC-
134a (new equipment), but HCFC-123 is scheduled
for phase-out longer term by provisions of the
Montreal Protocol and the United States Clean Air
Act. . Performance and environmental properties are
presented for CFC-1 I alternatives HCFC-123, HFC-
134a, and HFC-245ca.
HCFC-22 is also scheduled for phase-out, and
three alternatives for HCFC-22 have been identified:
HFC-134a, a near-azeotropic mixture of R32/Rl25,
and a zeotropic mixture of R32/R125/R134a.
Performance test results, future potential energy
efficiencies, and environmental properties are
presented for these alternative refrigerants.
