PURPOSE:To make it possible to remove blur promptly, by selecting the defroster blow-off mode by means of a control switch to increase the rate of outside air intake irrespective of any one of the operating modes, and as well by increasing the cooling capacity of a cooling device. CONSTITUTION:When the defroster blow-off mode is selected by a control switch 92, an inside and outside air switching damper is actuated to increase the rate of outside air intake irrespective of the controlled conditions of an inside air switch 86 and an outside air switch 87 which control the rate of inside air and outside air due to the inside and outside air switching damper. Further, the cooling capacity of a cooling device is increased irrespective of the controlled conditions of an economy switch 88 and an air-conditioning switch 89 which adjust the cooling capacity of the cooling device. Accordingly, air outside of a passenger compartment which is relatively dried, is further dehumidified through an air-conditioning duct, and then is blown onto a windshield to remove blur thereon, promoptly. Then, when the automatic control switch 90 is again operated, the original air-conditioning operating mode is reset. |
