<p>PURPOSE:To correct a set temperature automatically in accordance with a relative humidity and a set wind velocity and obtain an air conditioning having the same disagreeable index at all times by a method wherein the captioned control system is provided with a function to calculate the disagreeable index. CONSTITUTION:When an A.C. voltage, divided by resistors R1, R2 and generated by a transformer Tr, is impressed to a thermistor TH1 for correcting a humidity detecting element and a humidity detecting element TH2, the A.C. voltage in reverse proportion to the relative humidity is obtained at both terminals of the element TH2 and a voltage VC=VB+(VB-VA) is generated at the point C of a differential amplifier IC1. This output is inputted into a comparator IC3 through an amplifier IC2 after divided by resistors R8, R9 and is compared with a voltage VE divided by a set temperature regulating volume VR1 and a room temperature detecting thermistor TH3 to control a compressor relay RY3 in accordance with the result of the comparison. The voltage VD between the resistors R8, R9 is corrected based on the switching position of an air volume switching switch SW2.</p> |
