Abstract

PURPOSE:To enable an upward directed air flow having a small eddy current to be realized within an entire room by a method wherein an air blowing port for use in blowing air in a radial direction and under a distribution of equal speed from a horizontal direction toward a vertical direction is arranged over two opposing circumferences or an entire circumference of a corner where a wall and a floor are contacted to each other and then a suction port is arranged at a ceiling surface. CONSTITUTION:In a room where a closed state is normally applied, a blowing port 1 for blowing in a substantial radial direction and in a substantial equal speed distribution from a substantial horizontal direction toward its substantial vertical direction at two opposing circumferences or an entire circumference of a corner where a wall 6 and a floor 4 are contacted each other. A suction port 3 is arranged at a substantial central part 5 of a ceiling. The air blowing port 1 and the suction port 3 are connected by ducts 15 and 16 and the air is circulated. A filter 17 for use in collecting contaminated substances such as smoke of tobacco as well as a fan 8 are provided in a duct 16. With such an arrangement, it is possible to realize an upward directed small air flow distribution in an entire room and thus to prevent an eddy region or stayed region in the air flow.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air purification system that highly efficiently purifies the air in rooms such as indoors of houses and offices.

[Prior Art] In the conventional air cleaning system, there was an air cleaning system in which fresh air is blown out from a wall surface and sucked in at a ceiling surface for collection and purification.

Figure 4 shows an example of an air purification system that blows out air from the wall (23) and sucks it in at the ceiling (24).
) had a suction port (22). The air blown in from the suction port (22) is sent into the room through a fan (25) for blowing air.

[Problem to be solved by the invention]

In conventional air purification systems, vortices are generated in spaces such as indoors, and some areas are not purified.

Referring to FIG. 4, areas A and Bjl in the figure specifically showing a conventional purification example form a vortex, which causes dust and the like to accumulate, making it difficult to purify the area.

Another example of an air purification system is a clean room in a semiconductor factory, etc., but it cannot be applied to houses, offices, etc. because the air volume is enormous.

[Means to solve the problem]

In order to solve the above-mentioned problems, the air cleaning system of the present invention provides an air cleaning system with a substantially constant velocity in a substantially radial direction from a substantially horizontal direction to a substantially vertical direction on two opposing sides or the entire circumference of a corner where a wall and a floor meet. Equipped with an outlet that blows out air in a distributed manner,
It consists of a suction port placed on the ceiling surface.

[For production]

The air cleaning system configured as described above has air outlets that blow out air in a substantially radial direction and with a substantially uniform velocity distribution on two opposing sides or on the entire circumference of the corner where the wall and floor meet. It is possible to distribute the blowing airflow with less entrainment. By arranging the inlet in the center of the ceiling, an upward airflow distribution with small vortices can be achieved throughout the room.

This prevents vortex regions and flow stagnation regions in the air flow.

〔Example〕

An example will be described using figures.

The air purification system of the present invention is installed on the walls (6) and floors (4) in a room normally used in a closed state, as shown in Figure 1.
) are in contact with each other on two opposite sides or around the entire circumference, there are air outlets (1) that emit air in a substantially radial direction from a substantially horizontal direction to a substantially vertical direction with a substantially uniform velocity distribution, and approximately in the center of the ceiling (5). A suction port (3) is provided.

Further, in this embodiment, the above-mentioned blowout port (1) and suction port (3) are connected by ducts 05) and 06) to circulate the air. Inside the duct 06) there is a fan (8) and a filter (7) for collecting pollutants such as cigarette smoke.

The above-mentioned air outlet (1) is an air outlet (1) that is curved in an arc from the horizontal direction to the vertical direction, as shown in Fig. 2(a), in order to blow air in a substantially radial direction and with a substantially uniform velocity distribution. 1) A felt-like resistor with large pressure loss 0
7), or as shown in Figure 2(b) (setting grill C! (D) to make the wind direction radial and uniform in the air outlet (1)). are doing.

Note that when carrying out the present invention, the outlet (1) and the inlet (3) are not of the circulation type as in the embodiment shown in FIG.
The outlet (9) and the inlet θω may be connected to the outside air separately without being connected by lω. Fresh air is taken in from the outside air and contaminated air is discharged to the outside air.

[Effects of the Invention] With the configuration described above, the air cleaning system of the present invention can realize upward airflow distribution with small vortices throughout the room.

Therefore, combined with the self-raising power of contaminated air, the air in the room can be efficiently purified.

Furthermore, if the cycle is set to an open cycle as in the embodiment shown in FIG. 2, the air can be cleaned more completely.
