To eliminate a feeling of anxiety and a feeling of discomfort of an occupant, so as to prevent comfort of the occupant from being impaired just after the occupant gets on a vehicle.SOLUTION: A vehicular air conditioner is provided with: a refrigerant circuit including a compressor, an indoor heat exchange part and an external heat exchange part; an air conditioning unit in which the indoor heat exchange part is arranged; and a control device that controls the refrigerant circuit and the air conditioning unit. The refrigerant circuit has a hot gas bypass that decompresses at least a portion of a refrigerant compressed by the compressor and returns the portion to the compressor without going through the indoor heat exchange part and the external heat exchange part. The control device can execute hot gas heating operation by which the refrigerant is prevented from absorbing heat in the external heat exchange part and heat of the portion of the refrigerant compressed by the compressor is radiated in the indoor heat exchange part to heat a vehicle interior, which executes preparatory operation by which heat radiation is prevented or suppressed in the indoor heat exchange part to make the refrigerant circuit circulate the refrigerant until the refrigerant is brought into a predetermined state, when it is determined that the hot gas heating operation is executed based on a predetermined execution condition, before an occupant gets on a vehicle.SELECTED DRAWING: Figure 2

    【課題】乗員の不安感や不快感を無くし、搭乗直後の乗員の快適性が損なわれないようにする。【解決手段】車両空調装置は、圧縮機、室内熱交換部、及び、外部熱交換部を含む冷媒回路と、室内熱交換部を内部に配置した空調ユニットと、冷媒回路及び空調ユニットを制御する制御装置と、を備え、冷媒回路は、圧縮機で圧縮した冷媒の少なくとも一部を、室内熱交換部及び外部熱交換部を経由することなく減圧して圧縮機に戻すホットガスバイパスを有し、制御装置は、外部熱交換部において冷媒に吸熱させず、圧縮機で圧縮した冷媒の一部を室内熱交換部で放熱させて車室内を暖房するホットガス暖房運転を実行可能であり、車両への乗員の搭乗前に、予め定めた実行条件に基づいてホットガス暖房運転を実行すると判定された場合に、冷媒が所定の状態になるまで、室内熱交換部における放熱をさせず又は抑制させて、冷媒回路に冷媒を循環させる準備運転を行う。【選択図】図2
