To provide a refrigeration cycle device capable of suppressing oil stagnation in a heat exchanger for a battery.SOLUTION: A refrigeration cycle device includes: a selector valve switching between a battery mode in which a refrigerant flows to a heat exchanger for a battery and a non-battery mode in which the refrigerant does not flow to the heat exchanger for the battery; and a control section for controlling a compressor and the selector valve. The control section includes an estimation section for estimating an oil stagnation amount which is an amount of lubricating oil accumulated in the heat exchanger for the battery along with execution of the non-battery mode. The control section includes a determination section for determining whether recovery of the lubricating oil in the heat exchanger for the battery is required or not on the basis of the oil stagnation amount. The control section includes an execution section for executing an oil recovery mode for recovering the lubricating oil in the heat exchanger for the battery when the determination section determines that recovery of the lubrication oil is required.SELECTED DRAWING: Figure 13

    【課題】電池用熱交換器内のオイル寝込みを抑制する冷凍サイクル装置を提供する。【解決手段】冷凍サイクル装置は、電池用熱交換器に冷媒を流す電池モードと、電池用熱交換器に冷媒を流さない非電池モードとを切り替える切り替え弁と、圧縮機と切り替え弁の制御を行う制御部とを備えている。制御部は、非電池モードの実行に伴って電池用熱交換器内に溜まった潤滑オイルの量であるオイル寝込み量を推定する推定部を備えている。制御部は、オイル寝込み量に基づいて、電池用熱交換器内の潤滑オイルを回収する必要があるか否かを判定する判定部を備えている。制御部は、判定部が潤滑オイルを回収する必要があると判定した場合に、電池用熱交換器内の潤滑オイルを回収するオイル回収モードを実行する実行部を備えている。【選択図】図13
