Abstract

PURPOSE:To perform cool-down or heat-up operation of a car room in a short length of time simultaneously improve its quietness, by controlling air quantity of a blower and an opening degree of an air mixing door by stages in accordance with a level of deviation between car room temperature and preset temperature. CONSTITUTION:When a blower motor 22 and air mixing door 15 arranged in a ventilation duct are controlled by a microcomputer 31, firstly a correction value on the basis of outside air temperature from an outside air temperature sensor 6 is added to a temperature difference between preset temperature of a temperature lever 3 and car room temperature of a car room temperature sensor 5 to obtain a deviation value, and the motor 22 is operated at maximum speed before the deviation value becomes the first prescribed value. Secondly exceeding the first prescribed value, as the above described deviation value decreases speed of the motor is reduced, when the deviation value reaches the second prescribed value, the motor 22 is operated at constant speed. On the other hand, the above described door 15 is actuated to a maximum degree of room cooling or heating opening when the above described deviation value is not less than the second prescribed value, and its opening is controlled in accordance with reduction of the deviation value.
