Abstract

PURPOSE: To enable to effect a synthetic temperature control by a compressor, an indoor fan and the like by a method wherein a dfferential amplifier connecting with a temperature regulator at one side of the input terminal thereof and with a temperature sensor circuit at the other side of the input terminal thereof is provided and the output thereof is controlled.
CONSTITUTION: The differential amplifier 13 connecting with the temperature regulator 2 at one side of the input terminal thereof and with the temperature sensor circuit 1 by a thermistor at the other side of the input terminal thereof is provided and the circuit is constituted so as to be able to control the compressor 5 and the fan motor 7 by only the output thereof. Upon room heating, when the room heating is begun from a temperature lower than T31, for example, the compressor 5 is operated and the motor 7 is rotated at a high-speed rotation RH since the output voltage thereof is lower than V1. Subsequently, when the temperature is risen and the output voltage V1 (room temperature T31') is attained, the speed of the motor 7 is brought into a stepless speed change area proportional to the value of the room temperature and the number of revolution thereof is decreased as the temperature is risen. Thereafter, when the output voltage V2 (room temperature T32') is attained, the number of revolution of the motor becomes RL and it is restricted at RL even when the room temperature is risen to the temperature higher than T32'.
