<p>A heat transfer system (20) employing refrigeration principles including a compressor, a condenser, a metering device (24), and an evaporator (25) utilizing a heat exchanging liquid line subcooler (23) for subcooling the working fluid flowing between the condenser and metering device (24) is described. In one embodiment, the subcooler (23) is located in close proximity to the evaporator and in the path of cold air passing through and out from the evaporator (25). In another embodiment, the subcooler (23) is physically abutting the evaporator (25) and located in the path of cold air passing through and out from the evaporator (25) so as to be able to further reduce the temperature of the working fluid flowing in the subcooler (23) through heat exchange between the evaporator (25) and the subcooler (23) by forced convection and thermal conduction to increase the liquid portion of the liquid-vapor mixture in the working fluid entering the metering device (24).</p> |
