AIR CONDITIONING DEVICE
FIG6 is a schematic diagram for explaining an example of a relationship between an air flow from the air conditioning device according to an Embodiment 1 of the present invention and a person
The air blowing control unit 185 is control means for controlling the air blowing mechanism in accordance with the detection result of the human body detection unit 183 and the determination result of the work state determination unit 184. In particular, the air blowing control unit 185 controls the air blowing mechanism to blow air toward the upper part of the person at a first wind speed (arrow A in FIG6) when a person is working. At the same time, the air is blown toward the lower part of the person at a second wind speed (arrow B in FIG6). The second wind speed is different from the first wind speed. That is, as indicated by the arrow A in FIG6, a relatively slow wind which is diffused in a wide range is sent to the upper part of the person. Further, as indicated by the arrow B in FIG6, a relatively fast which is wind narrowly throttled is sent to the lower part of the person. In the relatively slow wind which is diffused in a wide range, the wind blown out from the inlet port 111 easily mixes with the surrounding air and tends to approach the temperature of the surrounding air before reaching the person. Meanwhile, in the relatively fast wind which is narrowly throttled, the wind blown out from the inlet port 111 hardly mixes with the surrounding air and tends to reach the person while maintaining the temperature at the time of blowing out from the inlet port 111. In the case of one air conditioning device as shown in FIG6 or the like, it is necessary to control the distribution of blown air with a plurality of wind direction plates, whereas by using a plurality of air conditioning devices 100, it is possible to form a cold-head and warm-feet temperature distribution by sending winds with different speeds toward the upper part and lower part of the person with a simpler configuration. Further, even in an environment where there is a plurality of persons, for example, such as an office, the wind speed can be made different between the upper part and the lower part for each of a plurality of persons, and it is possible to form a cold-head and warm-feet temperature distribution for each person. Which outlet ports of which air conditioning devices 100, among the plurality of outlet ports of the plurality of air conditioning devices 100, to use for blowing air to the upper part side or lower part side of the person may be appropriately set depending on the position of the person in the room and the like.
