Abstract:
When there is a command for pre-air conditioning to be performed, an inlet switches to an inside air recirculating mode and a compressor and a blower fan are driven to blow air that was drawn in toward a lower portion in a vehicle cabin (130 to 136). Then when a door switch detects that an occupant may get into the vehicle (100, 102), air is blown from an outlet toward the upper portion in the vehicle cabin while the inlet remains in the inside air recirculation mode (114 to 124). That is, cooled air in the lower portion in the vehicle cabin is drawn in, cooled, and then blown toward the occupant. Also, when starting the pre-air conditioning, the battery state-of-charge is detected and pre-air conditioning is prohibited if the battery state-of-charge is less than a predetermined value (116, 126, 128).
