Abstract
An air conditioning system for a vehicle is composed of a control unit which controls an air switching door, an element for detecting a clean-air level of the outside air and a vehicle speed sensor. The control unit controls the air-switching door to set to the outside-air mode when the clean-air level is higher than a reference level and to the inside-air mode when the clean-air level is not higher than the reference level. The control unit holds the inside-air mode until the vehicle speed becomes higher than a predetermined speed irrespective of the clean-air level.
