||The paper reports results of an evaluation of HFC-245fa as a potential alternative for CFC-11 in low pressure chillers. This paper gives results of an initial evaluation of HFC-245fa (1,1,1,3,3-pentafluoropropane) and updated results of HFC-245ca testing. HCFC-123 (1,1-dichloro-2,2,2-trifluoroethane) is currently the only alternative refrigerant for low pressure CFC chillers. This chlorine-containing alternative is scheduled for a production cap beginning in 1996, followed by a production phase-down through the year 2030, at the end of which production must cease. This phaseout timeframe is expected to allow new equipment designed for use with HCFC-123 and placed into service in the next few years to be utilized over the useful lifetime of the equipment. Meanwhile, the search for a long-term alternative continues.
