PURPOSE:To always utilize the electric power of a solar battery properly and efficiently by detecting the output of the solar battery and controlling the number of ventilating fans which are driven through motors by the electric power of the solar battery. CONSTITUTION:A front ventilating passage 2 which communicates to the inside and outside of a car compartment is arranged in the front part of an automobile 1, and a pair of rear ventilating passages 4a and 4b are arranged similarly in the rear part. Ventilating fans 3, 5a, and 5b are arranged in the front and rear ventilating passages 2, 4a, and 4b. While, a solar battery 8 for supplying electric power into each fan driving motor is arranged in the roof part 7 of the vehicle 1. In the lower part of a front window shield 9, a solar radiation sensor 10 is arranged, and a control circuit 11 for controlling each fan driving motor is arranged. Therefore, the output of the solar battery 8 is detected by the solar radiation sensor 10, and the number of ventilating fans 3, 5a, and 5b in operation is controlled according to the output. |
