Detection and Analysis of Microbial Contamination in Central Air Conditioning System of a University

Abstract:

Objective: Test the wind pipe dust and microorganism pollution status in the central air conditioning system of public buildings in the teaching area.Analysis of microbial pollution of the related factors.Methods:Sampling 6 functionally different area in the teaching building,using the microbiology analysis method on air conditioning system of blower tube surface dust pollution of microorganism detection,and the use of TiO₂ photo catalyst purification mechanism on microbial contamination control.Results:on the basis of"centralized air ventilation system in public places sanitary specification",teaching areas of central air conditioning system of dust amount met the requirement basically.Bacterial concentrations generally beyond the standard,fungal concentration accords with the standard.The Method using TiO₂ photo catalysis sterilization was proposed. Conclusion:Teaching of regional air conditioning pipe inner product dust weight is relatively large.Microbial pollution is serious.It is necessary that cleaning air conditioning system timely and using TiO₂ Photocatalyst purification mechanism for killing air duct surface dust microorganism.
