２９を出力する。Further, a change in room temperature is converted into a change in the resistance value of the suction temperature thermistor 12. When the resistance value of the suction air temperature thermistor 12 changes, the potential at the non-inverting input part of the amplifier 31 increases and becomes smaller as the resistance value of the suction air temperature thermistor 12 increases due to the partial pressure with the resistor 33. Then, the potential decreases. Therefore, the output section of the amplifier 34 is connected to the resistor 35 and the resistor 86.
The non-linear characteristics of the thermistor are changed into linear characteristics by changing the potential generated by the partial voltage between the thermistor and the voltage changing linearly. Further, the amplifier 37 amplifies the voltage output from the amplifier 34 by the amplification degree of the resistance value ratio of the resistor 38 and the resistor 89, and inputs the output voltage (3) to the differential amplifier 40 as a room temperature value. Next, the operation when the switching signal of the switching signal generating device 13 is 'L' will be explained. When the switching signal 31 'L' is input to the liquid crystal panel switching device 41, the liquid crystal panel switching device 41 When the output of the DC voltage to the liquid crystal panel 42 is stopped, the radiant heat is allowed to pass through, and the radiant temperature can be detected by the suction air temperature thermistor 12.Therefore, by repeating the same operation as the room temperature detection operation, , the output voltage ■4 is input to the differential amplifier 40 as a radiation temperature value.
3. The differential amplifier 40 inputted with v4 outputs V8-v.
4 is performed and a temperature distribution voltage 29 indicating the temperature distribution state of the room is output.
