To provide an air conditioner for a vehicle which can shorten time from start of defrosting operation to heating operation resumption.SOLUTION: A heat exchange core part 115 which includes fins 113 disposed on a plurality of heat exchange tubes 112 and ventilation gaps 116 between the respective adjoining heat exchange tubes 112 is provided on outdoor heat exchanger 11 of a heat pump type refrigeration cycle constituting an air conditioner for a vehicle. A plurality of heat exchange paths P1, P2, P3 comprising the plurality of heat exchange tubes 112 lined up in a row are provided on the heat exchange core part 115. An air flow adjustment device 4 which adjusts passage range when outdoor air passes through the heat exchange core part 115 of the outdoor heat exchanger 11 is provided on front side of the heat exchange core part 115 of the outdoor heat exchanger 11. The air flow adjustment device 4 comprises shutters 40, 41, 42 which are disposed on front side of each of the heat exchange paths P1, P2, P3 so as to correspond to each of the heat exchange paths P1, P2, P3 of the heat exchange core part 115. Each of the shutters 40, 41, 42 opens/closes independently.SELECTED DRAWING: Figure 3
【課題】除霜運転の開始から暖房運転再開までの時間を短縮しうる車両用空調装置を提供する。【解決手段】車両用空調装置を構成するヒートポンプ式冷凍サイクルの室外熱交換器11に、複数の熱交換管112および隣り合う熱交換管112どうしの間の通風間隙116に配置されたフィン113を有する熱交換コア部115が設けられ、熱交換コア部115に、連続して並んだ複数の熱交換管112からなる熱交換パスP1,P2,P3が複数設けられている。室外熱交換器11の熱交換コア部115の前側に、車室外空気が室外熱交換器11の熱交換コア部115を通過する際の通過範囲を調節する空気流れ調節装置4が設けられている。空気流れ調節装置4は、熱交換コア部115の各熱交換パスP1,P2,P3と対応するように各熱交換パスP1,P2,P3の前側に配置されたシャッタ40,41,42を備えている。各シャッタ40,41,42は個別に開閉する。【選択図】図3
