ABSTRACT:
A solar radiation detecting device for an automobile air-conditioner includes a left solar radiation sensor, a right solar radiation sensor and a horizontal solar radiation sensor for detecting quantities of the sunlight coming into the passenger compartment of an automobile so that an incident direction, an incident altitude and an incident intensity of the sunlight are calculated based on the detecting solar radiation quantities. The incident direction and altitude are used to vary the distribution air discharged from a vent outlet of the air-conditioner into the passenger compartment.
