ABSTRACT:
An air conditioning apparatus for an electric car capable of preventing condensation from forming on windshields, while decreasing electric power consumption. A duct forms therein a first passageway connecting an inside air inlet 8 with a lower outlet (foot outlet) 10 for discharging an air flow toward a lower part of a passenger in a cabin, and a second passageway for connecting an outside air inlet 11 with a defroster outlet 12 for discharging an air flow toward an inside surface of a windshield. A heat exchanger(s) is (are) arranged in the duct to make contact with the flow of air in the first and second passageways so as to heat the flows of air therein. The inside air after being heated by the heat exchanger is discharged from the lower outlet 10 to the cabin, while the outside air after heating is discharged from the defroster outlet 12 toward the windshield.
