Abstract
A sensor (27) is provided to sense the humidity at the inner surface of a window of a vehicle interior. When the sensed surface humidity is above a certain value, the possibility of the window being fogged arises and the proportion of outside air to recirculated air is increased to 100% to reduce the interior humidity. When the surface humidity is above a higher value, the interior air control system (5) is operated to reduce the interior humidity by increasing the amount of inlet air, the inlet air temperature, etc.
