Abstract
The potential for leakage of CFCs, HCFCs, HFCs and HCs to the atmosphere as a result of leakage in vehicular refrigeration systems is reduced by employing conduits (42, 58 and 63) of relatively short length to interconnect closely grouped system components including a compressor (38), a condenser (44) and an evaporator (62). The condenser (44) includes a liquid flow path (46) in heat exchange relation with a refrigerant flow path (48) and the same is connected by conduit (52) to heat exchanger (36). The evaporator (62) also includes a liquid flow path (65) in heat exchange relation with a refrigerant flow path (60) and the same is connected by conduits (66, 67) to at least one heat exchanger (68, 69) remote from an engine compartment (22) in which the compressor (38), condenser (44) and evaporator (62) are housed. The close proximity of the components minimizes the charge of refrigerant required and thus reduces the amount of refrigerant that may potentially leak from the system.
