PURPOSE:To eliminate uncomfortable feelings, by stopping a blower when the difference between the outside temperature and the temperature of passenger's compartment of a vehicle is small while the outside temperature is in a middle temperature range, and when the amount of solar radiation is less so that no affection is given to the passenger's effective temperature. CONSTITUTION:An opening degree control system for an air-mix door 16 determines the opening degree of the door 16 in accordance with the information of a desired blow-out air temperature and the information of an intake-air temperature, and therefore, controls the door 16. During the control of this door, it is always discriminated by a blower fan control section whether the outside temperature Ta is in the following range: 10deg. C<=Ta<=20deg. C or not, whether the temperature difference DELTAT between a set temperature Tptc and the temperature of the passenger's compartment Tr is in the following range:¦DELTAT¦<1deg. C, or not, and whether the amount of solar radiation Qsun is the following range Qsun<=alpha(Kcal/m<2>h) or not. Further, if the above-mentioned terms are all satisfied, a voltage application control signal which is the output of the blower fan control section is stopped so that a fan motor 11 is deenergized. Accordingly, the air blow for the passenger's compartment which gives unconfortable feelings is ceased in such a condition that the temperature of the passenger's compartment becomes around the set temperature. |
