Summary:To provide a refrigeration cycle device capable of suppressing a reduction in the heat exchange ability of a heat storage heat exchanger to improve defrosting performance and also improve heating ability.SOLUTION: An outdoor unit 10 including a compressor 11, a four-way valve 12, an outdoor heat exchanger 13, and a heat storage tank 30 provided on the outer periphery of the compressor 11 and storing a heat storage material 31 and a heat storage heat exchanger 40, and an indoor unit 20 including an indoor heat exchanger 21 are connected to each other via a refrigerant pipe 16 (a pipe where refrigerant flows). Between the intake side of the compressor 11 and the four-way valve 12, a three-way valve 18 is provided for switching between a pipe for carrying the refrigerant from the four-way valve 12 directly to the suction side of the compressor 11 and a pipe for carrying the refrigerant from the four-way valve 12 via the heat storage heat exchanger 40 to the suction side of the compressor 11. During defrosting operation, the three-way valve 18 is switched so that the refrigerant flows from the four-way valve 12 to the heat storage heat exchanger 40, and the refrigerant flows from the lower side of the heat storage heat exchanger 40 to the upper side.SELECTED DRAWING: Figure 2 【課題】本開示は、蓄熱熱交換器における熱交換能力の減少を抑制し、除霜性能の向上と暖房能力の向上を図ることのできる冷凍サイクル装置を提供する。【解決手段】圧縮機１１と、四方弁１２と、室外熱交換器１３と、圧縮機１１の外周に設けられかつ蓄熱材３１と蓄熱熱交換器４０とが収容された蓄熱槽３０と、を備えた室外機１０と、室内熱交換器２１を備えた室内機２０とを、冷媒配管１６（冷媒が流れる配管）を介して接続する。圧縮機１１の吸入側と四方弁１２との間に、四方弁１２から圧縮機１１の吸入側に直接冷媒を流す配管と、四方弁１２から蓄熱熱交換器４０を介して圧縮機１１の吸入側に冷媒を流す配管との切り替えを行う三方弁１８を設ける。除霜運転時に、三方弁１８を冷媒が四方弁１２から蓄熱熱交換器４０に流れるように切り替え、蓄熱熱交換器４０の下方から上方に向かって冷媒が流れるように構成した。【選択図】図２
