Abstract
PURPOSE: To raise accuracy in detection of temperature by constituting a temperature sensor by a thermistor in a temperature controlling circuit for an air conditioner and to enable to change the level and the differential when the apparatus is turned ON and OFF with ease by employing a variable resistor.
CONSTITUTION: A resistor 25 and a thermistor 8 serving as a temperature sensor are connected in series, so that a resistance change of the thermistor 8 is converted into a voltage change and applied to a negative input terminal of a differential amplifier consisting of an operational amplifier 10 and fixed resistors 26W28. To a positive input terminal of the differential amplifier, on the other hand, there is applied the output of a temperature controller consisting of a variable-resistance temperature controller 9 and fixed resistors 23, 24. The output of the differential amplifier is given to comparators C1, C2 including operational amplifiers 11, 12 for effecting on-off control of a compressor relay 17 and a relay 18 for an auxiliary heater on the basis of the output of the comparators C1, C2. Here, the level when the relays are turned ON is controlled by variable resistors 37, 38. Further, the differential when the relays are turned ON and OFF is changed by substituting fixed resistors 29, 33 by variable resistors or the like.
