Air conditioner for car

Abstract

Abstract PURPOSE:To prevent the partial inclination of the car-interior temperature due to the change of the solar radiation direction by arranging solar radiation sensors at several places in the car interior and controlling the air amount blown- out from each blowing-out port according to the output of each sensor. CONSTITUTION:Each value of the opening degree of wind distributing doors 32d and 33d, solar radiation amount 30l and 30r, set room-temperature 13, room temperature 14, outside air temperature 15, the opening degree of an air mix door 7d is input into a control circuit 34. The aimed blowing-out temperature T0 is determined in an aimed blowing-out temperature calculation part 18a, and the opening degree of the air mix door is set to a prescribed value X0 through an air mix door opening-degree calculation part 18b. Similarly, the opening degree of the wind distributing door is driving-controlled 40 and 41. When a difference is generated in the solar radiation amount 30l and 30r, a control circuit 34 transmits the control signal for the opening degree of the wind distributing door according to the difference, and drives the driving circuits 40 and 41, and the change to the wind amount corresponding to the solar radiation amount is performed. With such constitution, comfortableness can be improved.
