ABSTRACT:
A refrigerant cycle system includes a first heat-exchanging portion for condensing gas refrigerant discharged from a compressor, a gas-liquid separator into which all of refrigerant after passing through the first heat-exchanging portion and a part of gas refrigerant discharged from the compressor are introduced, and a second heat-exchanging portion for cooling and condensing refrigerant flowing from the gas-liquid separator. Because all of the condensed refrigerant from the first heat-exchanging portion is introduced into the gas-liquid separator, a passage area of a gas refrigerant introduction passage for introducing gas refrigerant from the compressor into the gas-liquid separator can be set relatively large. Therefore, a dimension difference of the gas refrigerant introducing passage in manufacturing is not greatly affected to an adjustment of a liquid refrigerant amount in the gas-liquid separator.
