In addition, since a plurality of discharge holes 32 are installed and the blowing nozzles 11 installed at the respective discharge holes 32 can be changed in direction, the blowing directions of the respective blowing nozzles 11 are different from each other to precisely send air to every corner. It becomes possible.

The temperature / humidity sensor 17 senses the temperature and humidity of the air and applies the signal to the controller 16 while cooling and dehumidification are performed in such an operation. Then, the controller 16 compares the set temperature and humidity with the measured temperature and humidity applied from the temperature / humidity sensor 17 and determines that the measured temperature and humidity have reached the set temperature and humidity. Stops driving.

While repeating the above process, the temperature and humidity of the space to be cooled and dehumidified are maintained at the set temperature and humidity.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the embodiments set forth herein.
