摘要：

Dedicated mechanical subcooling cycles utilize a small mechanical vapour-compression cycle, coupled to the main cycle at the exit of the condenser, to provide subcooling to the main refrigeration cycle. The amount of subcooling, the thermal lift of the subcooling cycle, and consequently the performance of the overall cycle, can be directly related to the temperature of the subcooling cycle evaporator. In this paper, the optimum value of the subcooling evaporator temperature is predicted using an ideal dedicated subcooling cycle. These results are then compared with those generated from a property-dependent model. The consideration of this optimum subcooling evaporator temperature leads to a design rule for the optimum distribution of heat exchange area for the dedicated subcooling cycle.
