REFRIGERATION CYCLE DEVICE

A refrigeration cycle device is provided with: a switching valve for switching between a battery mode in which a refrigerant flows to a battery heat exchanger and a non-battery mode in which the refrigerant does not flow to the battery heat exchanger; and a control unit that controls the compressor and the switching valve. The control unit is provided with an estimation unit that estimates an oil retention amount, which is the amount of lubricating oil stored in the battery heat exchanger as the non-battery mode is executed. The control unit is provided with a determination unit that determines whether or not it is necessary to recover the lubricating oil in the battery heat exchanger on the basis of the oil retention amount. The control unit is provided with an execution unit that executes an oil recovery mode in which the lubricating oil in the battery heat exchanger is recovered when the determination unit determines that the lubricating oil needs to be recovered. 制冷循环装置具备：切换阀，该切换阀切换制冷剂向电池用热交换器流动的电池模式和制冷剂不
