摘要：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 airconditioning 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 numbers of CFU are 600cfu/cm2 and 140cfu/cm2 respectively. No matter constant or variable temperature conditions, the reproduce rate of Penicillium spp. is faster than Cladosporium spp. 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 Cladosporium spp. has the same tendency.
