In the following operation description, the step numbers shown in FIG. 3-1 are indicated in parentheses.

First, by using the input setting operation section 14 of the air conditioner 1,
After setting the target and starting the operation (31), the fourth

Fan 62 is not operated. On the other hand, when the circulation fan 8 is stopped, the atmosphere moving fan 62 is operated constantly or intermittently to improve the response to detecting the indoor air atmosphere.

In FIG. 8, parts with the same reference numerals as those in FIG. 7 are the same parts as in the example of FIG. 7, so the explanation thereof will be omitted.

On the other hand, the air atmosphere detection unit 4A shown in FIG. It is connected to the harmonizer main body 1, and 82, 82° 82 corresponds to the air atmosphere detection section 4A.

With this configuration, the detection unit can be placed near the person in the room, and the indoor air atmosphere can be controlled more appropriately and with good responsiveness.

The atmosphere moving fan 62 (see Fig. 7) is rotated in the opposite direction to the air atmosphere detection unit 4 (4A) to allow clean air after cleaning the air atmosphere to flow in at predetermined intervals. Each sensor in the atmosphere detection section can be refreshed, and the air atmosphere can always be detected with high accuracy.

In the above embodiment, a case has been described in which the air atmosphere detection section 4 is equipped with all the sensors, but there is no problem in function and effect even if the air atmosphere detection section is installed in several locations. In particular, the temperature sensor and humidity sensor may be installed separately from other sensors without any problem.
