Description of the Related Art As shown in FIG. 6 (B), the conventional air conditioning system is generally a complete mixing type air conditioning system in which the air in the room is positively agitated by the force of air supply, and is generated in the room 2. Alternatively, the pollutant 1 accompanied by the inflowing heat is diluted, diffused, and neutralized by the ambient air, but the pollutant 1 is not completely removed. Therefore, if you try to bring the volume of the room to a temperature below a certain set value or below a permissible value or air quality, you have to increase the air volume and lower the air supply temperature considerably in a room with a high ceiling. There is a problem of consuming a lot of.
