초록

In a refrigerant cycle system, refrigerant compressed in a first compressor is cooled and condensed in a radiator, and refrigerant from the radiator branches into main-flow refrigerant and supplementary-flow refrigerant. The main-flow refrigerant is decompressed in an expansion unit while expansion energy of the main-flow refrigerant is converted to mechanical energy. Thus, the enthalpy of the main-flow refrigerant is reduced along an isentropic curve. Therefore, even when the pressure within the evaporator increases, refrigerating effect is prevented fr...

청구항

[ What is claimed is:] [1.]1. A refrigerant cycle system comprising:a radiator for cooling a compressed refrigerant;an inner heat exchanger in which refrigerant from said radiator branches into first-flow refrigerant and second-flow refrigerant, and the second-flow refrigerant is decompressed to perform a heat exchange between the first-flow refrigerant and the decompressed second-flow refrigerant;an expansion unit for decompressing and expanding the first-flow refrigerant having been heat-exchanged with the second-flow refrigerant;an expansion-energy re...
