ある。That is, when the user sets an appropriate set temperature TS using the microcomputer, if the room temperature TA is - set temperature TS + 2 degrees, then the pattern shown in Figure 3a will be followed, and the room temperature TA will be TS + 2 > TA > TS. If the temperature is between the two, the outdoor unit and the indoor unit are operated according to the pattern shown in Figure 3B, and when the room temperature TA is lower than the set temperature TS, the outdoor unit and the indoor unit are operated according to the pattern shown in Figure 3C. This method uses a microcomputer, which is not only expensive, but also has the disadvantage that setting the set temperature TS is difficult for the setter to remember unless the room temperature at the time of setting is known.

For example, if the reference signal of the interval room temperature setting circuit aek is set to 25 degrees Celsius, if the room temperature is below 25 degrees, no output will be output from the comparator a9 intervening in the interval room temperature setting circuit (le). , the capacitor C intervening in the interval timer circuit 09 is connected to the interval timer circuit 09 for a time set by resistors R8 and R9, for example 3.
Repeat charging for 5 minutes and discharging for 5 minutes, for example, set by the resistor r1H, and at the time of charging, an output is obtained at the output terminal of the comparator 2, and the transistor Tr as a switching element.

インターバルで室外器（１）とを運転する。When the room temperature becomes equal to or higher than the reference setting temperature, the resistance of the thermistor Th decreases and an output signal is generated in the comparator a9. According to this, conduction occurs between the emitter and collector of the transistor Tr, which is the interval switching circuit 0, and the dehumidifying interval circuit a &
The resistor r8 intervening in is assumed to be the ground voltage value. Therefore, the resistance r
Since the capacitor C is charged only through the capacitor C, the charging time is extended by the increased resistance to, for example, 5 minutes, and the outdoor unit (1) is operated at intervals of 5 minutes.
