PURPOSE:To enable sensing of open air contamination even when the vehicle is at a standstill etc., and provide controllability for the suction of outer air by sensing the operating condition of the vehicle, driving a forced air supply device in accordance with the obtained result, and by sending the open air forcedly to an open air contamination sensor. CONSTITUTION:This airconditioner for vehicle includes an inner/outer air switching device for vehicle 16 and a temperature adjusting device 17. Here the inner/outer air switching device 16 consists of an open air contamination sensor 12, an operating condition sensor 15, a control device 13 in which the signals therefrom are entered, and a forced air supply device 14 under control thereupon. An outer air suction prohibition signal is given to a solenoid valve 10 only when the outer air contamination signal is greater than the set value. Thereby a negative pressure actuator 9 is operated to rotate an intake door 8 toward an outer air suction hole 6, and inner air is introduced from an inner air suction hole 7. When outer air flowing into the outer air contamination sensor 12 is insufficient, the forced air supply device 14 is actuated. |
