PROBLEM TO BE SOLVED: To solve a problem that in an air conditioner that is controlled so that a refrigerant is trapped in piping within an outdoor heat exchanger or piping within an indoor heat exchanger, a probability that the refrigerant is leaked from a refrigerant circuit increases.SOLUTION: In this air conditioner 1, when leakage of a refrigerant is detected during operation, when an operation stop instruction is issued or when the operation is stopped, the operation is performed while a closing mechanism located downstream in a refrigerant flowing direction of a storage container 22 out of a first solenoid valve 23 (first closing mechanism) and a second solenoid valve 24 (second closing mechanism) is closed, and then a closing mechanism located upstream in the refrigerant flowing direction of the storage container 22 is closed, so as to store the refrigerant flowing in a refrigerant circuit in the storage container 22. 【課題】冷媒が室外熱交換器内の配管または室内熱交換器内の配管に閉じ込まれるように制御される空気調和機では、冷媒回路から冷媒が漏れる確率を高くしてしまうことになる。【解決手段】この空気調和機１では、運転時において冷媒漏れが検知された時、運転停止指示があった時、または運転停止時に、第１電磁弁２３（第１閉鎖機構）及び第２電磁弁２４（第２閉鎖機構）のうち貯留容器２２よりも冷媒流れ方向下流側の閉鎖機構が閉鎖された状態で運転が行われたあとで、貯留容器２２よりも冷媒流れ方向上流側の閉鎖機構が閉鎖されることで、冷媒回路を流れる冷媒が貯留容器２２に貯留される。【選択図】図２
