Problems solved by technology

[0003] In large commercial buildings with large area and high space, such as comprehensive shopping malls and office buildings, due to the dense flow of people and relatively closed space, the air quality in commercial buildings is poor. The design is complicated, and the harmful substances and pollutants in the building are often not properly diluted and replaced.
The combination of the above factors has led to the deterioration of air quality in existing large commercial buildings
At present, the ventilation method in large-scale commercial buildings in my country is mainly mecha

Abstract

The invention relates to an intelligent adjusting system for air quality in a large-scale commercial building and an adjusting method of the intelligent adjusting system. The intelligent adjusting system is characterized by comprising a fresh air inlet, a fresh air channel, a fresh air chamber, a return air inlet, a return air channel, a return air chamber, a heat exchanger and a controller which are mounted in a shell. The adjusting method comprises the following steps: 1) setting a preset value; 2) calculating an air quality deviation value I; 3) dividing I value section and establishing the solenoid valve openings corresponding to different sections.

Description

Technical field [0001] The invention relates to the technical field of air conditioners, in particular to an adjustment system that can improve the quality of air conditioners in large commercial buildings. Background technique [0002] With the development of economy and the rapid improvement of quality of life, people have higher and higher requirements for air quality. Because air-conditioning technology is still immature in air purification, people are paying more and more attention to the problem of indoor air pollution in air-conditioning. After research, it is found that indoor fresh air volume is an important factor in determining indoor air quality. [0003] In large commercial buildings with large areas and high spaces, such as comprehensive shopping malls, office buildings, etc., due to the dense flow of people and the relatively closed space, the air quality in the commercial buildings is poor. At the same time, the commercial buildings have a wide variety of operation...
