PROBLEM TO BE SOLVED: To provide a vehicle air conditioner for an electric vehicle, capable of managing defrosting operation time according to the power state of the vehicle and setting a balance between the recovery of a sufficient heat absorbing ability of an outdoor heat exchanger and the securing of a traveling distance at the time of restarting the vehicle.SOLUTION: During the defrosting operation of removing frost stuck to an outdoor heat exchanger 24, a high-temperature and high-pressure refrigerant compressed by a compressor 21 is introduced to the outdoor heat exchanger 24. Control means stops, in the case of executing a defrosting operation at the time of power supply from the outside of the vehicle, the defrosting operation when a temperature near the outdoor heat exchanger 24 rises equal to or more than a first prescribed temperature, and stops, in the case of executing a defrosting operation at the time of no power supply from the outside of the vehicle, the defrosting operation when the temperature near the outdoor heat exchanger 24 rises equal to or more than a second prescribed temperature lower than the first prescribed temperature.SELECTED DRAWING: Figure 1

    【課題】車両の電力事情に応じて除霜運転時間を管理し、車両の再発進時における室外熱交換器の充分な吸熱能力の回復と走行距離の確保をバランスさせることができる電動車両の車両用空調装置を提供する。【解決手段】室外熱交換器24に付着した霜を除去する除霜運転時には、コンプレッサ21によって圧縮された高温高圧の冷媒を室外熱交換器24に導入する。制御手段は、車両外部からの給電時に除霜運転を実行する場合には、室外熱交換器24の近傍の温度が第1の規定温度以上に上昇したときに除霜運転を停止し、車両外部からの非給電時に除霜運転を実行する場合には、室外熱交換器24の近傍の温度が第1の規定温度よりも低い第2の規定温度以上に上昇したときに除霜運転を停止する。【選択図】図1
