To achieve heat recovery of air in a vehicle cabin while suppressing equipment cost.SOLUTION: A vehicle air conditioner includes: a refrigerant circuit; a heat medium circuit heat-exchanging with the refrigerant circuit; a main air conditioner; an auxiliary air conditioner provided with a heat exchange part of the heat medium circuit; and a control device controlling operations of the refrigerant circuit, the heat medium circuit, the main air conditioner and the auxiliary air conditioner. The control device executes a heat recovery mode recovering heat from the air in the vehicle cabin in the auxiliary air conditioner when the execution determination part determines that air conditioning by the auxiliary air conditioner is unnecessary.SELECTED DRAWING: Figure 1

    【課題】設備コストを抑えながら車室内空気の熱回収を実現できるようにする。【解決手段】車両用空調装置は、冷媒回路と、冷媒回路と熱交換する熱媒体回路と、主空調装置と、熱媒体回路の熱交換部を備える補助空調装置と、冷媒回路と熱媒体回路と主空調装置と補助空調装置の動作を制御する制御装置とを備え、制御装置は、実行判定部により、補助空調装置による空調の不要を判断した場合に、補助空調装置にて車室内空気から熱を回収する熱回収モードを実行する。【選択図】図1
