PURPOSE:To prevent the blowing of odor, etc., into a pair of air passages into a car compartment by permitting the ventilation in a pair of air passages by driving a blower in one air passage in the state where a blowing port opening/ closing dampers in a pair of air passages are closed and a communication port opening/closing damper is opened. CONSTITUTION:When an air conditioner is started by an air conditioning switch 9a on an operating panel 9, the blower 31 in the first air passage 21 is operated by a control circuit 10, and the blowing port opening/closing dampers 41 and 42 in the both air passages 21 and 22 are closed, and a communication port opening/closing damper 12 is opened. The inside/outside air selecting damper 81 in the first air passage 21 is switched to the inside air communication state in which an inside air taking-in port 8b is opened, and the inside/outside air selecting damper 82 in the second air passage 22 is switched to the outside air communication state in which an outside air taking-in port 8c is opened. Therefore, the air in the car compartment is introduced into the second air passage 22 from the first air passage 21 through a communication port 11 by the blower 31, and discharged outside through a blower 32 in stop state, thus discharging the staying hot air and odor in the both air passages 21 and 22. |
