This study investigated methods to reduce the use and release of chlorofluorocarbon (CFC) refrigerants and evaluated alternatives to CFCS in air-conditioning and refrigeration systems. A life cycle cost (LCC) analysis formed the basis for evaluation. A literature review examined applicable CFC directives, containment methods, replacement refrigerants, and alternative processes. The results of the LCC analysis showed that maintaining the existing CFC system was always the least costly alternative. When forced to replace a CFC reciprocating package unit, the best replacement was a non-CFC reciprocating unit. The most practical replacement for reciprocating chillers was a new reciprocating chiller for systems less than 150 tons, and screw chillers for systems 150 tons or larger. Retrofitting a centrifugal chiller was cost-effective if the system had been in service no more than 11 years for a 200-ton unit, 17 years for a 400-ton unit, and 18 years for a 1000-ton unit. otherwise, 200-ton units should be replaced with screw chillers and 400 and 1000-ton units with centrifugal chillers....
