PROBLEM TO BE SOLVED: To suppress fogging when dew condensation water is evaporated from an indoor heat exchanger.SOLUTION: A refrigeration cycle 40 includes: a cooling heat exchanger 24 that functions as an indoor heat exchanger. When a refrigerant flows through the cooling heat exchanger 24, the cooling heat exchanger 24 cools air. At this time, dew condensation water adheres to the cooling heat exchanger 24. When cooling by the cooling heat exchanger 24 is ceased, an air conditioning control unit 60 switches an indoor air-outdoor air switching device 22 into an outdoor air mode. Further, the air conditioning control unit 60 actuates a window heater 10 so as to heat a windshield 9. Accordingly, fogging of the windshield 9 is suppressed. The suppression of fogging by the outdoor air mode and actuation of the window heater 10 is insusceptible to a signal sent from a dew condensation sensor 62 but is continued over a predetermined period of time. |
