In conventional air conditioners, the indoor temperature is controlled by controlling the indoor temperature controller to start and stop the compressor and the 7-amp air cooler for the heat source side heat exchanger (condenser) at the same time. was. However, if the configuration is such that the air cooling for the condenser is stopped at the same time as the compressor is stopped, a large amount of the high-temperature O high-pressure refrigerant in the condenser is transferred to the user-side heat exchange II (evaporator ), the refrigerant heat causes the condensed water that adheres to the evaporator surface to re-evaporate into the room, increasing indoor humidity.

Next, when the normally closed contact 14b and normally open contact 14m of the multi-temperature control relay 14 are reversed by the detection signal from the indoor temperature detector 13 (the normally open contact 14 is closed and the normally closed contact 14b is opened),
Although the compressor drive motor 15 stops, one wind-cooling fan drive motor continues to rotate due to the slow operation of the delay relay 16, and the wind-cooling fan 7 continues to operate together with the blower fan 2.

The change in cooling capacity in the above-mentioned condition will be explained with reference to FIG. In the same figure, the horizontal axis shows the elapsed time t, the figure shows the on/off state of the compressor 40, the figure (6) shows the on/off state of the storm cooling fan 1 and 7, and the figure shows the instantaneous cooling capacity Q. are shown respectively. In the same figure, when cooling is restarted at point 1-O, the cooling capacity Q shows a delay in startup, and then ? [Compression s4 stops at the time of stable primary 1■t0. Then, the high-pressure, high-temperature refrigerant in the outdoor heat exchanger 5, which is working as a condenser, tries to flow toward the indoor heat exchanger 1, which is working as an evaporator, due to the pressure difference. However, at this time, since the air cooling unit 7 is continuously operated, the high-pressure high-temperature refrigerant in the 1w1 internal heat exchanger 1 is cooled, and the refrigerant heat flowing to the indoor heat exchanger 1 is reduced. As a result, the amount of reevaporation of condensed water adhering to the fins of the indoor heat exchanger 1 is smaller than before, and the cold storage effect of the indoor heat exchanger 1 is reduced between 1-1 and t in Fig. 3. , a positive cooling capacity Q is obtained. The cooling capacity Q (indicated by the broken line) in the conventional case during this time is
Positive cooling capacity Q-II due to cold storage effect for a certain period of time
However, after that, the condensed water is re-evaporated into the air-conditioned room due to the heat of the refrigerant from the indoor heat exchange ill, resulting in a negative cooling capacity Q, and then returns to Q-0. Therefore, in conventional operation, negative cooling capacity would occur when the compressor was turned off.

With this configuration, the air conditioner neutralizing compressor 40 can be turned on and off (when returning to school, when the compressor 4 is turned off, the amount of condensed water that re-evaporates into the room is small, and the humidity in the room increases significantly. There is no fear.

In this embodiment, the case of an air conditioner is shown, but the case is not limited to this. Therefore, the heat escaping from the indoor heat exchanger 1 to the outdoor heat exchanger 5 is reduced by 1%, and the temperature of the air blown indoors does not drop significantly.
