Indoor Air Quality Assessment And Purification Researach

This thesis mainly aims at the current situation and developing trend of the indoor air quality of domestic housing and makes a further research of the evaluation method and purification method of the indoor air quality.The problem of the indoor air quality is caused by the numerous contaminants. There have already existed many relevant findings of the indoor air quality but the effect is comparatively weak. The diseases caused by the terrible indoor air quality happen every year, such as the Leukaemia. At the same time, the stronger house tightness leads to insufficient ventilation and worse air quality.Although people have already realized the relationship of the health and the indoor air quality, for the lack of knowledge, the consciousness of this problem is still not enough. In this paper, this thesis will analyze the pollution sources, the evaluation and purification method, and the existing problems of the indoor air quality.This thesis focuses on the evaluation method of the indoor air quality and the steps are as follows:the thesis evaluated the air quality by fuzzy mathematics and gray system theory firstly and then put emphasis on the purification method, especially the rotary catalytic air purifier and proved the good effect of this air purifier on indoor air quality via experiments. And finally, this thesis made the suggestion of improving the indoor air quality on the basis of the relevant research status.
