Abstract

PURPOSE:To make it possible to obtain the same effective temperature at all times with out being affected by the variation of humidity by a method wherein in case the room temperature is set at a desired value, the set value is made to be corrected within a temperature range covering all the temperatures generating in the ordinary life, in response to the variation of the room humidity. CONSTITUTION:The AC voltage of a transformer Tr is divided and the divided voltage is impressed upon a humidity sensing element TH2 through a temperature correcting thermister TH1 so that a voltage reverse proportional to the humidity is generated from the humidity sensing element TH2. Further, a DC voltage VA corresponding to the humidity is generated from an amplifier IC1 on the base of the output of the element TH2 and impressed upon a differential amplifier IC4 where it is compared to a DC voltage VB which corresponds to about 50% of the humidity. In addition, a voltage VC which has been obtained as a result of the above comparison is inputted to a gain variable inversion amplifier IC5 and the output VD of the amplifier IC5 is compared to a point E voltage divided by a room temperature setting volume R2 and a resistor R8 in another inversion amplifier IC6 so that the operation of a compressor Comp is controlled on the bases of the result of comparison obtained in the amplifier IC6 and the output of a room temperature detecting thermister TH3.
