Abstract

PURPOSE:To prevent car windows from clouding even at the intermission of a refrigerating cycle by providing a compressor-stop detecting means and a means to switch over an air-intake door to the side of outdoor-air introdution. CONSTITUTION:When an air-conditioner relay 14 is off to close a contact 14b, negative pressure is directly introduced from a vacuum tank 56 into a negative pressure actuator 10 via electromagnetic valves 19 and 20 without reference to a negative pressure switch valve 9, and thereby, an air-intake door 8 is moved by the negative pressure actuator 10 to a position C for introducing outer air fully. In this construction, when an outer air switch 13 is opened and a refrigerating cycle is stopped, outer air is introduced through the air-intake door 8 to reduce the temperature in a car room, and the reduced thermal difference between the inner and the outer air serves to prevent car windows from clouding, and ensure a safety driving.
