PROBLEM TO BE SOLVED: To provide an air-conditioning system for vehicle capable of carrying out sterilization cleaning of a heat exchanger.SOLUTION: An objective air conditioning system for vehicle makes it possible to obtain the sterilization cleaning action in a wide range by: discharging a cleaning fluid such as hypochlorous acid having a sterilization action from a cleaning fluid discharge means 9 toward a heat exchanger 5c in such a state as stopping a blowing means 4 operating a temperature adjusting means 5 installed in an air duct 6 to cool the surface of the heat exchanger 5c making the sterilization component of the cleaning fluid attach and absorb on the surface of the heat exchanger 5c together with a dew condensation water and spreading the sterilization component all over the surface of the heat exchanger 5c.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】本発明は、熱交換器の殺菌洗浄を行なうことができる車両用空調システムを提供することを目的とする。【解決手段】送風手段4を停止した状態にて、殺菌作用をもつ次亜塩素酸などの洗浄液を、洗浄液放出手段9から熱交換器5cに向けて放出するとともに、風路6内に設置された温度調整手段5を動作させて、熱交換器5c表面を冷却し、熱交換器5c表面に洗浄液の殺菌成分を結露水とともに付着、吸収させて、熱交換器5c表面を隅部まで殺菌成分を到達させ広範囲に殺菌洗浄作用を得る。【選択図】図1
