To provide a refrigeration cycle device which can downsize a supercooling part of a condenser to be used, and which can reduce the amount of a refrigerant to be used.SOLUTION: An air conditioner 1 for vehicle comprising a refrigeration cycle device includes a compressor 2, a condenser 3, an expansion valve 4 and an evaporator 5. The condenser 3 comprises a condensation part 10; a supercooling part 11; and a liquid receiver 12 for separating a gas-liquid mixed phase refrigerant which has flowed out from the condensation part 10 into a gas phase refrigerant and a liquid phase refrigerant, and for delivering a liquid phase principal refrigerant to the supercooling part 11. The liquid receiver 12 includes a refrigerant cooler 33 for exchanging heat between a refrigerant which flows out from the evaporator 5 and before flowing into the compressor 2 and a refrigerant which flows out from the condensation part 10 of the condenser 3 and before flowing into the supercooling part 11.SELECTED DRAWING: Figure 1

    【課題】用いられるコンデンサの過冷却部を小型化しうるとともに、用いる冷媒量を減少しうる冷凍サイクル装置を提供する。【解決手段】冷凍サイクル装置からなる車両用空調装置1は、圧縮機2、コンデンサ3、膨張弁4およびエバポレータ5を備えている。コンデンサ3が、凝縮部10と、過冷却部11と、凝縮部10から流出した気液混相冷媒を気相冷媒と液相主体冷媒とに分離するとともに液相主体冷媒を過冷却部11に送り出す受液器12とからなる。受液器12が、エバポレータ5から流出するとともに圧縮機2に流入する前の冷媒と、コンデンサ3の凝縮部10から流出するとともに過冷却部11に流入する前の冷媒とを熱交換させる冷媒冷却器33を備えている。【選択図】図1
