To provide a vehicle air conditioner 1 configured to protect a refrigeration cycle from a refrigerant at abnormal high pressure without using a communication pipe.SOLUTION: An electronic control device 60 includes a high pressure protection unit configured to prevent pressure of a high-pressure refrigerant from being increased to abnormal high pressure at the time of operation of a refrigeration cycle 20 in a state where the refrigerant is maintained inside the refrigeration cycle 20 (step S131, step S132, step S141). The electronic control device includes a relief device 25A configured to release the refrigerant to the outside of the refrigeration cycle 20 when the pressure of the refrigerant inside the refrigeration cycle is increased to abnormal high pressure at the time of shut-down of the refrigeration cycle 20.SELECTED DRAWING: Figure 1
【課題】連通配管を用いることなく、異常高圧の冷媒から冷凍サイクルを保護するようにした車両用空調装置１を提供する。【解決手段】電子制御装置６０は、冷凍サイクル２０の運転時に、冷凍サイクル２０の内部に冷媒を維持した状態で高圧冷媒の圧力が異常高圧になることを抑える高圧保護部（ステップＳ１３１、ステップＳ１３２、ステップＳ１４１）を備える。冷凍サイクル２０の停止時に、冷凍サイクル内の冷媒の圧力が異常高圧になったとき、冷媒を冷凍サイクル２０の外側に放出するリリーフ装置２５Ａとを備える。【選択図】図１
