Summary

Investigates central air conditioning systems in 27 public buildings with 6 different function in Beijing and Changsha. Analyses the pollution status of the systems in two cities. Correlation analysis is made on 9 indices concerning air speed, inside room and inside surfaces of air ducts by means of a statistical analysis software SPSS V16.0. The result shows that the bacteria and epiphyte pollution in supply air and in indoor air in Changsha, due to the high level of relative humidity, is heavier than in Beijing and the density of PM10 in Beijing, due to heavy atmosphere particle pollution, is higher than in Changsha. The amount of accumulated dust on inside air ducts has positive correlation to the content of microbe in the dust, the density of PM10 in supply air and in indoor air and the total amount of bacteria in supply air and in indoor air.
