Abstract
PURPOSE: To perform stable control, by integrating a temperature detection output signal and using the integrated signal to actuate or stop an air conditioner.
CONSTITUTION: The output terminals A, B of a temperature detection circuit 1, which is a bridge circuit composed of resistors 5, 6, 7 and a negative-characteristic temperature sensor 8, are connected to an integration circuit 2 which comprises an operational amplifier 9 and a capacitor 10 which serves as a feedback impedance. The output terminal C of the integration circuit 2 is connected to a switching circuit 3 which comprises reference potential determining resistors 11, 12, an operational amplifier 13, a transistor 14, a feedback resistor 15 for effecting positive feedback from the output terminal of the amplifier 13 to its uninverted input terminal and resistors 16, 17 for applying bias to the base of the transistor 14. Switching is effected by an excitation winding 4. Feedback is effected from the output terminal of the amplifier 13 to the inverted input terminal of the other amplifier 9 through another resistor 18 to determine the hysteresis width of the switching circuit 3.
