Abstract: Indoor air quality has a great impact on our health, and there are many reasons contributing to the pollution of indoor air. At present, people have widely concerned about air-conditioning system, which is regarded as potential microbial pollution sources. The study is about separation and identification of fungal microorganisms on the surface of the central air-conditioning system filters, and then doing research on the colonies and mycelium grown and reproduce regular of fungal microorganisms in different thermal environment, which aim to lay the groundwork of effective air microbial contamination solved by thermal methods. This study has shown that Penicillium spp and Cladosporium spp are dominant fungi, and the number of CFUs is 600 and 140 cfu/cm(2), respectively. No matter constant or variable temperature conditions, the reproduce rate of Penicillium is faster than A. glaucus and the relationship between colony diameter and time is liner relation. Through these constant and variable experiments, it is found that variable temperature does obvious restrain on Penicillium spp, while A. glaucus has the same tendency.
