PURPOSE:To make it possible to air-condition by providing a warm air passage containing a condenser and a cold air passage containing an evaporator in a vehicle, respectively, and by feeding warm air and cold air flowing out from this warm air and cold air passages into a car room by selecting them by means of a blow-off port switching door in an electric car not provided with cooling water, etc. CONSTITUTION:Closing an air conditioning switch causes a compressor 16 and blowers 6, 7 to be driven and refrigerant to circulate through a refrigerant cycle. Warm air heated through a condenser 4 from a warm air passage 2 and cold air cooled through an evaporator 5 from a cold air passage 3 is blown off from outdoor blow-off passages 12a, 13a having been opened according to each mode and from indoor blow-off passages 12b, 13b. During the stage of cooling, the air taken in the cold air passage 3 may be either internal air or fresh air, an inside- outside air switching door 11 is allowed to stay in an arbitrary position, and the blow-off switching door 15 acts as the indoor blow-off passage 13b. And, for the arm air passage 2, both a fresh air port passage 8a and the fresh air blow-off passage 12a are opened. On the other hand, during the stage of warming, an inside-outside air switching door 10 is allowed to stay in an arbitrary position and a blow-off port switching door 14 shifted to the indoor blow- off passage 12b side, and for a cold air passage 3, both a passage 9a and the passage 13a are opened, allowing the cold air to be discharged to the outside of car. |
