To provide a vehicular air-conditioner capable of increasing heating performance in a vehicle cabin when the heating performance in the vehicle cabin does not reach a target heating performance.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, is equipped with refrigerant channels 10a, 10c, 10d, 10e, 10f, 10g, and 10h as a first path in which the refrigerant passing through the compressor 11 flows to an upstream side of an accumulator 15, and refrigerant channels 10a, 10c, 10i and 10h as 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 calculates a target heating performance that is a target value of heating performance in a vehicle cabin, and controls a flow rate of the refrigerant flowing in the second path on the basis of the calculated target heating performance.SELECTED DRAWING: Figure 4

    【課題】車室内の暖房能力が目標暖房能力に達していない場合に車室内の暖房能力を増加させ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経路としての冷媒流路10a,10c,10d,10e,10f,10g,10h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経路としての冷媒流路10a,10c,10i,10hと、を備え、制御装置200は、車室内の暖房能力の目標値である目標暖房能力を算出し、算出した目標暖房能力に基づいて第2経路を流れる冷媒の流量を制御する。【選択図】図4
