Abstract
PURPOSE:To obtain the precise control to start the blowing-off of air in an air conditioner constructed to check the blowing-off until a fixed temperature is obtained by quickening the start of the blowing-off when the outside temperature is high for heating and low for cooling. CONSTITUTION:When the outside temperature is very low, the voltage drop is great at an outside temperature sensor 12, and an electric potential Vb at a point (b) is high. Consequently, a comparator 13 cannot be on, unless the resistance of an engine water temperature sensor 11 is reduced and an electric potential Va at a point (a) is increased higher than Vb. That is, when the water temperature is considerably risen, the amount of air can be controlled. Meanwhile, when the outside temperature is high, the voltage drop is small at the sensor 12, and Vb is reduced. Consequently, even if the engine water temperature is comparatively low, since Va is higher than Vb, the comparator 13 is on to connect a transistor 9, and a fan motor 1 is quickened in its driving via relays 6 and 3. The control of the blowing-off of cool air is carried on similarly.
