Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purification system for removing and treating pollutants such as tobacco generated indoors.

[0002]

2. Description of the Related Art As a conventional air purifier, a part of the air for air conditioning is purified by a purifier provided separately from the heat exchanger for air conditioning or a purifier incorporated in a part of the heat exchanger for air conditioning. A method is known in which the purified air is diffused throughout the room.

[0003]

However, in recent years when passive smoking of cigarettes has become a social problem, it is required to collect cigarette smoke without scattering it indoors. In the air purifying device of the diffusion type, a huge amount of processing air is required, and as a result, the size of the device becomes large, resulting in an increase in initial cost and an increase in running cost.

Therefore, a groove having an opening on the indoor side is provided on the ceiling, and an air flow (hereinafter, referred to as an air flow) toward the air inlet along the groove is provided.
This is called "groove flow". ) Is generated to attract and convey indoor cigarette smoke to the ditch flow, and a purification system that efficiently collects the cigarette smoke has been proposed. Since it is a system that supplies the generated air into the room separately from the groove flow, it is necessary to supply the air that is several times as much as the groove flow into the room, which increases the treatment air volume of the purification system and parts such as ducts. It was the main factor that increased the score.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to improve the trapping performance of contaminated air in a room with a small amount of air and to reduce the number of parts. The purpose is to provide an air purification system.

[0006]

In order to solve the above-mentioned problems, the present invention provides a ceiling with a groove 10 that is open to the inside of the room, and both ends of the groove 10 are air intake ports 13 that are open to the inside of the room.
And an air outlet 14 are provided, and the air outlet 14 is provided.
Is a groove-oriented outlet 1 that is provided so as to face the air inlet 13 and blows an airflow from the groove 10 toward the air inlet 13.
4a and the indoor-facing outlet 14 that blows out the airflow in the indoor direction
b, and the air intake port 13 and the air outlet port 14 are connected to a purifying device 16 including a blower 18, a purifying filter 17 and the like via a purifying duct 15 arranged in the ceiling 6 In the purification system, the purification duct 15 is communicated with an air conditioning duct 22 connected to the air conditioning heat exchange device 19.

Further, it is preferable that the indoor air outlet 14b of the purification duct 15 or the air inlet 13 also serves as an air conditioning outlet or an air conditioning inlet communicating with the air conditioning heat exchange device 19. Further, the purification device 16 has an air-conditioning air passage 30 communicating with the air-conditioning heat exchange device 19, and a bypass air passage 31 for preventing a part of the purified air from passing through the air-conditioning heat exchange device 19.
And an air volume adjustment damper 32 for adjusting the air volume in the air conditioning air passage 30 and the air volume in the bypass air passage 31 and an air volume sensor 25 for detecting the air volume varied by the air conditioning control. It is preferable that the blower 18 be controlled or the air volume adjustment damper 32 be adjusted based on the detection signal of No. 1, and the increased / decreased amount of air be made to flow into the purifying device 16 to control the amount of treated air required for purification.

Furthermore, it is preferable that the indoor air outlet 14b of the cleaning duct 15 is provided with means for switching the blowing direction of the purified air in accordance with cooling or heating.

[0009]

According to the present invention, since the purification duct 15 is made to communicate with the air conditioning duct 22 connected to the air conditioning heat exchange device 19, the air for air conditioning can be used for purification. Even when the amount of air from the purification device 16 is small, the shortage of the amount of air required for the groove flow A several times can be covered by the amount of air from the air conditioning duct 22. Therefore, the amount of air attracted by the groove flow A and the amount of air supplied to the room from the indoor-direction outlet 14b can be kept equal to each other without increasing the amount of treated air of the purifying device 16, and the smoke of the cigarette in the room can be maintained. Etc. can be efficiently removed and processed.
