Refrigerant cycle system with hot-gas bypass structure

摘要

In a refrigerant cycle system, a low-pressure side gas-liquid separator (35) is disposed between a refrigerant outlet side of an evaporator (32) and a refrigerant suction side of a compressor (10) so that gas refrigerant is sucked into the compressor, and a throttle passage (35a) through which liquid refrigerant is introduced into the compressor is disposed in the low-pressure side gas-liquid separator. Further, in a condenser (20) for condensing gas refrigerant discharged from the compressor in a cooling mode, both first and second heat-exchanging units (21, 22) are provided in this order in a refrigerant flow direction, and a high-pressure side gas-liquid separator (23) is disposed between the first and second heat-exchanging units. <IMAGE>
