PROBLEM TO BE SOLVED: To provide an air conditioner for vehicle capable of enhancing utilization efficiency of energy by allowing heat energy in a heat exhaust passage for ventilation to be restored both in a heating operation and a cooling operation, while suppressing pressure loss and heat loss.SOLUTION: An auxiliary heat exchange device 60 separated from a main heat exchange device is arranged in a position facing a heat exhaust passage. The auxiliary heat exchange device 60 switches one of an inside air heat exchange state in which a condenser 63 exchanges heat with the air inside a vehicle, an outside air heat exchange state in which the condenser 63 exchanges heat with the air outside of the vehicle, and a ventilation heat exchange state in which the condenser 63 exchanges heat with the ventilation air. The auxiliary heat exchange device 60 switches one of an inside air heat exchange state in which an evaporator 64 exchanges heat with the air inside the vehicle, an outside air heat exchange state in which the evaporator 64 exchanges heat with the air outside of the vehicle, and a ventilation heat exchange state in which the evaporator 64 exchanges heat with the ventilation air.SELECTED DRAWING: Figure 5

    【課題】圧力損失や熱損失を抑制しつつ、暖房運転時と冷房運転時のいずれにおいても換気用の排熱通路の熱エネルギーを回収できるようにして、エネルギーの利用効率を高めることができる車両用空調装置を提供する。【解決手段】主熱交換装置と分離した補助熱交換装置60は、排熱通路に臨む位置に配置する。補助熱交換装置60は、コンデンサ63を車室内の空気と熱交換する内気熱交換状態と、コンデンサ63を車室外の空気と熱交換する外気熱交換状態と、コンデンサ63を換気空気と熱交換する換気熱交換状態のいずれかに切り換える。補助熱交換装置60は、エバポレータ64を車室内の空気と熱交換する内気熱交換状態と、エバポレータ64を車室外の空気と熱交換する外気熱交換状態と、エバポレータ64を換気空気と熱交換する換気熱交換状態のいずれかに切り換える。【選択図】図5
