A low-noise centralized composite filtering method and system for fresh air supply

Abstract

The invention discloses a low-noise centralized composite type filtrating method for fresh air supply of a classroom, and further discloses a system realizing the method. A double-system independent operation and composite filtrating technology of outdoor fresh air filtrating and corridor circulating air filtrating is adopted, fan filtering boxes are placed on ceilings or roofs at the two ends ofa corridor, the classroom and the corridor form a one-way airflow, particle pollution of the classroom and the corridor is effectively controlled, and the good classroom air quality is maintained. According to the low-noise centralized composite type filtrating method for fresh air supply of the classroom, and the system realizing the method, through combined action of a classroom centralized-typefresh air system and a corridor centralized-type circulating air system, it is ensured that the indoor air quality of the classroom is not affected by outdoor heavy haze under the flowing condition of teachers and students, and the good indoor air quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of ventilation, and relates to a low-noise centralized compound filter system for fresh air supply. Background technique [0002] The concentration of outdoor particulate pollutants is becoming more and more serious under domestic smog weather. Classrooms, meeting rooms and other places are used as student learning places and meeting places, with dense population and a large demand for fresh air; in order to effectively ensure good air quality in buildings, fresh air is filtered play a vital role. Take the classroom as an example: At present, two fresh air fans are usually installed in the classroom to meet the fresh air requirements of the classroom. Because the fresh air needs to exchange heat with the exhaust air, it is usually necessary to drill 4 holes in the outer wall of each classroom, which has a certain impact on the classroom wall structure. damage, and the local negative pressure caused by class...

Problems solved by technology

[0003] The purpose of the present invention is to provide a low-noise centralized composite filter system for fresh air supply in densely populated places, for example, it can be used to solve the high noise of the fresh air filter system in the application scene of the school classroom, the wall is destructive, and the outdoor smog is easy to infiltrate , the problem of uncontrolled particle pollution in the corridor, realize the independent operation of the dual system of the classroom and the corridor, and the dual technical guarantee of composite filtration, and overcome the above-mentioned defects of the traditional classroom fresh air filtration scheme
