Why install filters in air conditioning purification vents


Why install a filter in the air purifying air outlet?

The filtering effect of air conditioning purification tuyere filters is an important factor affecting indoor air quality. It is of great significance in protecting end equipment and preventing cross-contamination of pollutants. In clean projects, increasing the efficiency of the return air filter can help prevent the degree of cross-contamination of pollutants from different workshops, and extend the service life of medium and high efficiency filters. The installation position of the return air filter is convenient for removal and replacement, does not affect the operation of the entire air conditioning system, and is convenient for decentralized management and control. The disadvantage is that the increase in the efficiency of the return air filter will increase its resistance. Some foreign designs usually increase the area of the return air to reduce the speed of the return air, thereby offsetting the requirements for the fan head. It is reasonable. At present, there are many filter materials on the market, which are sufficient to meet the requirements of filtration efficiency. However, the structure of the air outlet is difficult to remove and replace the filter screen, which restricts the selection of filter materials. Some openable air outlets are unreasonable in structure and tightly sealed. Can not meet the requirements, there is no good connection, easy to relax, rust, block. Some bead-type openable air vents are too strong when they are opened, which easily damages the decorative surface and deforms the air vent. Manufacturers and product developers should research and reform the structure of air conditioning purification air outlets, and develop practical new products. At present, the combined air outlets produced by some manufacturers have basically met the requirements for use, and can be easily disassembled and increased. The return air filtration efficiency. Designers should pay attention to the role of air conditioning purification return air filter to ensure the life of the end equipment and heat exchange efficiency. So as to ensure the normal operation of air quality and air conditioning system. Relevant departments should also organize experts and technicians to formulate relevant industry standards and limit the efficiency of the return air filter in order to better meet the needs of people's lives and work and the requirements of the production environment on the production process
