To provide a vehicular air-conditioner capable of suppressing a heat loss.SOLUTION: A bypass path in which a refrigerant passing through a compressor 11 detours a heater core 12 and flows into a suction side 11b of the compressor 11 includes a first path in which the refrigerant passing through the compressor 11 flows to an upstream sides of an accumulator 15, and a second path in which the refrigerant passing through the compressor 11 flows to a downstream side of the accumulator 15. A control device 200, in a hot gas heating mode, can switch to an accumulator bypass path in which the refrigerant flowing to the heater cores 12 flows into the suction side 11b of the compressor 11 via the first path and the second path so as to detour the accumulator 15.SELECTED DRAWING: Figure 7

    【課題】熱ロスを抑制することができる車両用空調装置を提供する。【解決手段】圧縮機11を通過した冷媒がヒータコア12を迂回して圧縮機11の吸入側11bに流入するバイパス経路は、圧縮機11を通過した冷媒がアキュムレータ15の上流側に流れる第1経路と、圧縮機11を通過した冷媒がアキュムレータ15の下流側に流れる第2経路と、を備え、制御装置200は、ホットガス暖房モードにおいて、ヒータコア12に流れた冷媒がアキュムレータ15を迂回するように第1経路と第2経路とを経由してから圧縮機11の吸入側11bに流入するアキュムレータバイパス経路に切り替え可能である。【選択図】図7
