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 indoor contaminants such as tobacco.

[0002]

2. Description of the Related Art As a conventional air purification device, a part of air conditioning air is purified by a purification device provided separately from a heat exchange device for air conditioning or a purification device incorporated in a part of the heat exchange device for air conditioning. A method of diffusing the purified air throughout the room is known.

[0003]

However, in recent years when passive smoking of cigarettes has become a social problem, it is required to collect cigarette smoke without scattering in the room. An air purifying device using a diffusion method requires a huge amount of processing air, which results in an increase in the size of the device, resulting in an increase in initial costs and running costs.

[0004] Therefore, a groove is provided in the ceiling to open to the indoor side, and an airflow (hereinafter, referred to as "airflow") along the groove toward the air suction port is provided.
It is called "groove flow". ), A purifying system has been proposed that attracts and conveys tobacco smoke in the room to the ditch to efficiently collect the tobacco smoke. This is a method to supply the air to the room separately from the channel flow, so it is necessary to supply the room with air several times as much as the channel flow, which increases the processing air volume of the purification system and parts such as ducts. This was a major factor in increasing scores.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to improve the performance of collecting contaminated air in a room with a small air volume and to reduce the number of parts. It is to provide an air purification system that can be completed.

[0006]

In order to solve the above-mentioned problems, the present invention provides a groove 10 which is formed on the ceiling on the indoor side, and an air inlet 13 which is formed on both sides of the groove 10 on the indoor side.
And an air outlet 14 are provided.
Is a groove-oriented outlet 1 that is provided to face the air inlet 13 and that blows out an airflow from the groove 10 toward the air inlet 13.
4a and a room-facing outlet 14 for blowing airflow toward the room
b, and the air suction port 13 and the air outlet 14 are connected to a purifying device 16 provided with a blower 18, a purifying filter 17 and the like via a purifying duct 15 disposed in the ceiling back 6. The purification system is characterized in that the purification duct 15 is communicated with an air conditioning duct 22 connected to an air conditioning heat exchange device 19.

Further, it is preferable that the indoor outlet 14b or the air inlet 13 of the purifying duct 15 also serves as an air-conditioning outlet or an air-conditioning inlet communicating with the air-conditioning heat exchanger 19. 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 that does not allow a part of the purified air to pass through the air conditioning heat exchange device 19.
An air volume adjustment damper 32 for adjusting the air volume in the air conditioning air channel 30 and the air volume in the bypass air channel 31; and an air volume sensor 25 for detecting the air volume changed by the air conditioning control. It is preferable that the control of the blower 18 or the adjustment of the air volume adjusting damper 32 is performed based on the detection signal, and the increased or decreased air amount is flown into the purification device 16 to control the processing air volume required for purification.

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

[0009]

According to the present invention, since the purification duct 15 is communicated with the air conditioning duct 22 connected to the air conditioning heat exchanger 19, the air conditioning air can be used for purification. Even if the amount of air from the purifying device 16 is small, the shortage of the amount of air required several times as much as the channel flow A can be covered by the amount of air from the air conditioning duct 22. Therefore, the amount of air induced by the gully flow A and the amount of air supplied into the room from the indoor-facing outlet 14b can be kept equal without increasing the amount of processing air of the purification device 16, and the smoke of tobacco in the room can be maintained. Etc. can be efficiently removed and processed.
