Abstract

The invention discloses a large-scale commercial air switch and its automatic control system, comprising an air inlet device, an air inlet device driving motor, an outdoor air detector, an inspection door, an air purification box, an air outlet grid, and an air outlet grid driving motor , indoor air detector and controller; the outdoor air enters the air purification box through the air inlet device, and after being filtered by the air purification box filter device, clean air is obtained, and flows into the room through the air outlet grille. The large-scale commercial air exchanger described in the present invention has a simple structure and a high degree of intelligence, adopts a polymer filter device, and has a good effect on air purification.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to an automatic control working process of a large-scale commercial air switch. Background technique [0002] With the continuous improvement of people's living standards, various decoration materials, furniture and daily chemicals have entered the room in large quantities, resulting in more and more sources and types of pollutants such as large shopping malls, industrial plants, large cinemas, hospitals, stadiums, etc. . At the same time, in order to save energy, the airtightness of modern buildings has been continuously strengthened, resulting in insufficient fresh air volume in large shopping malls, industrial plants, large theaters, hospitals, stadiums, etc., and on the other hand, large shopping malls, industrial plants, large theaters, and hospitals. , sports venues and other air pollution. [0003] At present, there are two problems when the air purifiers on the ...
