First, the configuration of the ozone air curtain device will be described.

As shown in the drawing, an ozone air curtain device 1 includes an air curtain device 2 that sucks air and blows out the air into a curtain shape, and an ozone generator 3 that generates ozone and sends ozone to the air blown out of the air curtain device 2. And an ozone concentration control device 4 for detecting the ozone concentration of the air blown from the air curtain device 2 (indicated by a broken line in the figure) and adjusting the amount of ozone generated by the ozone generator 3 according to the ozone concentration. I have.

The air curtain device 2 is provided with a pre-filter 6 for removing insects, large-size dust, dust and the like in the air inhaled from the room 5. This pre-filter 6
Is composed of a large mesh net or the like.

Downstream of the pre-filter 6, a main filter 7 for removing dust having a small particle diameter in the air is provided. The main filter 7 is made of a nonwoven fabric having a small mesh.

Downstream of the main filter 7, a blower 8 for sucking air in the room 5 and blowing the air into the room 5 is provided. The outlet of the blower 8 is formed in a slit shape so as to blow air in a curtain shape.

The solid line with an arrow in FIG. 1 indicates the flow of air.

The ozone generator 3 includes a compressor 11 for compressing and dehumidifying the sucked air, and the compressor 1
PS that extracts oxygen from air compressed in step 1 and concentrates it
The system includes an A-type oxygen generator 12 and an ozonizer 14 that generates ozone from the extracted oxygen.

The ozonizer 14 includes an air curtain device 2.
Ozone supply pipe 1 extending in the vicinity of the suction section 15 of the blower 8
6 are provided. The ozone supply pipe 16 is made of a material having a high rust prevention effect such as a stainless steel pipe in consideration of rust, and a plurality of blowout holes 17 for blowing out ozone are formed at an end of the blower 8 side.

The ozone concentration control device 4 is provided in the vicinity of the air curtain device 2 and detects an ozone concentration of air blown from the blower 8. An ozone concentration detector 18 is provided in accordance with the detected ozone concentration. And a control device 19 for adjusting the ozone generation amount.

The control device 19 is connected to the ozone concentration detector 18 and the ozonizer 14, and receives an ozone concentration detection signal from the ozone concentration detector 18 and
4, an ozone generation amount increase / decrease command signal is sent.

Specifically, under manned operation, the ozone concentration of the blown air is set and controlled so that it is always 0.08 ppm or less.

Next, the operation of the ozone air curtain device 1 having the above configuration will be described.

While the ozone concentration is detected by the ozone concentration detector 18 and the amount of ozone generated can be adjusted by the control device 19 in accordance with the detected ozone concentration, the ozone concentration of the blown air can be constantly maintained at a low level. It is possible to blow out the mixed air into the room 5 under manned operation.

According to an experiment, when the ozone concentration at the outlet of ozone is 0.08 ppm, it is 30 cm from the outlet.
It is known that the ozone concentration is 0.02 ppm or less at the distant points.

As described above, according to the ozone air curtain device 1, by blowing ozone into the room 5,
In addition to the heat blocking effect and insect repelling effect of the conventional air curtain, a deodorizing and sterilizing effect by ozone can be obtained.

Since the odor component is a particle, some of the odor component is attached to a wall, a ceiling, a floor, and the like, in addition to the one scattered in the air.

In a conventional air-conditioning system, indoor air is only sucked into an air conditioner, and the sucked air is deodorized and sterilized with ozone. Although the odorous component was decomposed, the odorous component attached to the wall, ceiling, floor, etc. could not be decomposed. On the other hand, in the ozone air curtain device 1, since the ozone can directly contact the odor component attached to the wall, the ceiling, the floor, and the like to be decomposed, a very excellent deodorizing effect can be obtained.

According to the above configuration, when the shutter 21 is open, the ozone air curtain device 1 is driven to obtain the same operation as described above. At night,
Under unmanned conditions, the shutter 21 can be closed to fumigate ozone into the room 5. The ozone concentration at this time is about 0.5 to 5 ppm, and the blowing of ozone is stopped 2 to 4 hours before a person enters the room. Thereby, intensive deodorization and sterilization of the room 5 can be performed.

Although the ozone air curtain device 1 can be provided outside the opening 22 to obtain the effect as an air curtain, in this case, it is not possible to fumigate the room 5 with ozone.
