Abstract
An apparatus for controlling an automobile air-conditioner wherein the direction of solar radiation is determined based on a signal which is obtained by retarding the leading edge of a solar radiation signal and the position of an air-distributing door is controlled according to the thus obtained signal. A signal whose leading and trailing edges are progressively increasing and decreasing, respectively, is used for the calculation of a signal corresponding to the thermal load in the vehicle passenger compartment. The operation of various components of the air-conditioner including a blower is controlled by the result of calculation of the thermal load signal.
