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, and a low temperature side heat exchanger 14 configured to exchange heat between a heat medium exchanging heat with an on-vehicle heating apparatus and a refrigerant. A control device 200, in a hot gas hating mode for flowing a part of the refrigerant passing through the compressor 11 to the heater core 12 and flowing the rest of the refrigerant to a bypass path, when the temperature of the heat medium flowing in the low temperature side heat exchanger 14 does not satisfy a predetermined condition, regulates the inflow of the refrigerant to the low temperature side heat exchanger 14.SELECTED DRAWING: Figure 3

    【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、車載発熱機器と熱交換する熱媒体と冷媒とで熱交換するように構成された低温側熱交換器14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、低温側熱交換器14を流れる熱媒体の温度が所定の条件を満たさないとき、低温側熱交換器14への冷媒の流入を規制する。【選択図】図3
