Study On The Performance Of Air Purifier And Purification Components In Office Building

People’s health and work efficiency are directly influenced by office building indoor air quality and the particulate matter pollution is one of the most important indexes to evaluate the office building air quality. In recent years, the office building indoor particulate matter pollution is more and more serious and it doesn’t cause enough attention. This article studies the effective methods to control of the office building indoor air pollution and the purification performance in this background.To begin with, the source of the office building indoor particulate matter pollution and the state are analyzed and tested in this paper to elaborate the seriousness of the particulate matter pollution of the modern office building. Then the performance parameters of the air purifiers which are used to control of the office building particulate matter pollution are discussed in this thesis and the influencing factors of the performance evaluation of air purifier are analyzed. Theoretical model of the air purifier is established and through the experiment in the 30 m3 large indoor air quality lab discusses the factors which influence the CADR of the air purifier, the dust sources and wind speed and evaluation method are emphasized. Finally, the air filter which are used in office building fresh air system are introduced in detail and a general ventilation air filter performance test bench is set up which mainly consists of the blower box, nozzle box, dust aerosol generation system, artificial system, particle sampling system, test system and terminal filter resistance and so on. The factors which affect the experimental platform of dust are discussed and this experiment machine performance is stable and convenient to test the air filter. Also the parameters on the performance of the air filter resistance, counting efficiency, let dust meter diameter are discussed. The air purification system can effectively control the office building indoor particulate matter pollution by the particle filtering performance tests in the actual office building.
