1. An air-conditioner for an automobile, comprising:
- (a) solar radiation quantity detecting means for detecting a quantity of solar radiation at the right side of a passenger compartment of the automobile and a quantity of solar radiation at the left side of the passenger compartment;
(b) solar radiating direction calculating means for calculating a solar radiating direction based on a solar radiation quantity signal detected by the solar radiation quantity detecting means;
(c) air-distribution control means for determining proportions of air to be distributed to the left side of the passenger compartment and air to be distributed to the right side of the passenger compartment according to the solar radiating direction calculated by the solar radiating direction calculating means;
(d) an air-distribution door operable under the control of the proportions of air determined by the air-distribution control means;
(e) a plurality of louvers disposed, respectively, at a plurality of upper air outlets facing to the passenger compartment, the louvers being capable of swinging to set the direction air-discharged from the respective upper air outlets; and
(f) louver control mean for controlling the direction of louvers so that said louvers are directed straight when an angle of deviation of the solar radiation direction relative to the direction of travel of the automobile is within a predetermined angle, and when said angle of deviation exceeds said predetermined angle, said louvers are tilted toward an occupant of the automobile.

Abstract
An automobile air-conditioner wherein a direction of the sunlight coming into the passanger compartment of an automobile is detected, and if a deviated solar radiation is present, air-distribution is controlled to increase and decrease the quantity of air discharged from upper air outlets according to the detected solar radiating direction, while at the same time, louvers disposed in the respective air outlets are directed to an occupant to force conditioned air directly against the occupant. In the absence of the deviated solar radiation, the louvers are not directed to the occupant.
