Description

Clean duct connection structure of indoor air ventilation system {Ventilation System of Indoor Air}

The present invention relates to an indoor air ventilation system, and more particularly, it is possible to maintain the airtightness of a flat duct with improved sealing force without the use of bonds, and to remove static electricity from the air to prevent stagnation of fine dust floating along the flat duct. The present invention relates to a clean duct connection structure of an indoor air ventilation system that can keep the interior of the flat duct circulating in the room clean by doing so, and the service life of the flat duct is extended, thereby further reducing additional costs.

In general, when a person breathes for more than a certain time in an indoor space that is blocked from outdoor air, the amount of carbon dioxide in the room increases, which interferes with breathing. In addition, toxic substances such as chemicals used in indoor construction materials and harmful substances generated by the use of office equipment such as copiers and printers can cause headaches and fatigue.

Accordingly, it is necessary to ventilate the indoor space. Although the user opens a window to ventilate, a ventilation device is also used. Such a ventilation device allows indoor and outdoor air to pass through a heat exchanger to reduce the temperature difference between outdoor air and indoor air, thereby making the indoor space comfortable. On the other hand, outdoor air contains pollutants such as yellow dust or fine dust, and the fine dust causes various diseases such as bronchial tubes and lungs.

However, since the conventional ventilation device cannot remove fine dust, etc. introduced from the outside, there is a problem that causes various diseases as described above.

On the other hand, recently, an air purifier is used separately from the ventilation device, but the air purifying is performed only after the air containing fine dust or microplastics is introduced into the room due to the ventilation operation. The problem that various diseases are caused by fine dust or microplastics cannot be solved. In addition, since the air purifier must be installed separately from the ventilation system, there is a problem in that the cost increases.

In addition, since a coupling is used as an accessory for connecting a reducer and a flat duct or a flat duct and a flat duct constituting the conventional indoor air ventilation system, adhesive connection is made using silicone (bonds) inside it, so environmental hormones are generated Of course, there is a disadvantage that disassembly and assembly between the ducts is very cumbersome and difficult.
