To provide a refrigeration cycle device capable of adjusting a temperature of air distributed to an air-conditioned space, and properly adjusting a temperature of a battery in a temperature zone lower than the distributed air.
A refrigeration cycle device includes a heat exchanger 12 for distributed air, heating indoor distributed air to be distributed to a cabin while applying a discharged refrigerant of a compressor 11 as a heat source, a high stage-side expansion valve 13a for decompressing a refrigerant flowing out from the heat exchanger 12 for distributed air, and a heat exchanger 15 for battery, heating the distributed air for battery to be blasted to a battery 55 while applying the refrigerant decompressed by the high stage-side expansion valve 13a as a heat source, a refrigerant discharge capacity of the compressor 11 is controlled so that a distributed air temperature TAV of the indoor distributed air approaches a target blow-out temperature TAO in a heating and warming-up mode for heating the indoor distributed air and also heating the distributed air for battery, and controls a throttle opening of the high stage-side expansion valve 13a so that a battery temperature Tb as a temperature of the battery 55 is kept within a predetermined reference temperature range.
