PURPOSE:To make proper air conditioning control immediately after an engine starts and to improve the comfortability inside a vehicle by adjusting the air conditioning start time, quantity of wind, and so on according to the temperature of engine cooling water. CONSTITUTION:A constant voltage converting circuit 3 which converts the voltage supplied from a power source to a constant voltage is incorporated inside a control unit 1. A wind quantity computing circuit 5 which receives the output signals from a water temperature sensor SN1, a mode switch SW2 and air conditioning switch SW3 and is connected to a timer 11 is also incorporated inside said control circuit 1. In addition, an opening position computing circuit 7 receiving the output signal from a sensor 9 which detects both the inside air and the open air temperature is placed inside the control circuit and sends the signal to the wind quantity computing circuit 5. The wind quantity computing circuit 5 computes the quantity of air blown our from a specific supply opening and controls respective transistors Q1 to Q3, whereby controlling the operation of a blower motor M via relays RY1 to RY3. |
