PROBLEM TO BE SOLVED: To suppress heat radiation loss in a first mode, in a refrigeration cycle device capable of switching the first mode in which blast air to an air-conditioned space is cooled by an evaporator and a second mode in which the blast air to the air-conditioned space is heated by a radiator.SOLUTION: A refrigeration cycle device comprises: a gas-liquid separator 17 that separates refrigerant flowing out from an outdoor heat exchanger 16 into gas phase refrigerant and liquid phase refrigerant, and can flow out the gas phase refrigerant and the liquid phase refrigerant individually; and switching means 18, 20 that switch a first mode refrigerant circuit flowing out the liquid phase refrigerant from the gas-liquid separator 17, flowing in it to second pressure decreasing means 21 and an evaporator 22, and further making a compressor 11 suction it, and a second mode refrigerant circuit flowing out the gas phase refrigerant from the gas-liquid separator 17 and making the compressor 11 suction it. |
