PURPOSE:To prevent a temperature difference from occurring between the left and right of a car compartment by adjusting the air flow rate through individual ventilator outlet ports in accordance with the difference between sunlight quantities of the left and right of the car. CONSTITUTION:A control circuit 2 determines the difference between sunlight quantities of the left and right based on sunlight quantity signals detected and fed by sunlight quantity sensors 1a, 1b provided on the left and right of a car, and sets dampers 4a-4d ventilator outlet ports 3a-3d respectively to predetermined damper apertures through servo circuits 5 in accordance with the difference between sunlight quantities of the left and right, thereby the air flow rate through individual outlet ports 3a-3d is automatically adjusted to the best distribution ratio in accordance with the sunlight quantities of the left and right. |
