This study measured the airborne microbes in the air conditioning equipment units for centralized air ventilation system as well as the dust associated microbes in a stadium in Dalian, and tested the environmental factors (temperature, humidity). Through collecting cotton test, microorganism cultivation and the colony statistics, we analyzed the status of microbial contamination in two groups of air conditioning units with different operating conditions. The points that the results showed are as follows: 1) The fungi and bacteria are widespread in the ac filter surface; 2) The number of microorganism on edges and against the wall is more than that in ac filter center; 3) The bacteria distribution density in measuring points is more than fungi and reflects a higher concentration; 4) The lay-off unit in low air velocity and high humidity has more microorganism; 5) The area of dust associated microbial pollution is serious.
