To provide a vehicular air-conditioner with a good quick warming performance.SOLUTION: A vehicular air-conditioner 1 is equipped with a refrigerant circuit 10 that includes a compressor 11, a heater core 12 configured to heat air to be supplied into a vehicle cabin, a decompression device 13, a low temperature side heat exchanger 14 in which a refrigerant exchanges heat, and a refrigerant channel 10x that is a low temperature side heat exchanger detouring the low temperature side heat exchanger 14. A control device 200, in a hot gas heating mode for flowing a part of a refrigerant passing through the compressor 11 to the heater core 12 and flowing the rest of the refrigerant to the bypass path, can perform control in which the refrigerant circulates in the compressor 11, the heater core 12, the decompression device 13, and the low temperature side heat exchanger bypass channel and detours the low temperature side heat exchanger 14.SELECTED DRAWING: Figure 6
【課題】速暖性のよい車両用空調装置を提供する。【解決手段】車両用空調装置1は、圧縮機11と、車室内に供給される空気を加熱するように構成されたヒータコア12と、減圧装置13と、冷媒が熱交換するように構成された低温側熱交換器14と、低温側熱交換器14を迂回する低温側熱交換器バイパス流路である冷媒流路10xとを含む冷媒回路10を備える。制御装置200は、圧縮機11を通過した冷媒の一部を前記ヒータコア12に流し、残りの冷媒をバイパス経路に流すホットガス暖房モードにおいて、冷媒を前記圧縮機11とヒータコア12と減圧装置13と低温側熱交換器バイパス流路とを循環させて低温側熱交換器14を迂回させる制御が可能である。【選択図】図6
