Objective To investigate the pollution status of centralized air conditioning and ventilation system in Tengzhou City and provide the basis for health management. Methods Sixteen central air-conditioning systems were randomly selected from four public places, including the hotels in the city. Pollution indexes such as the amount of accumulated dust in the pipeline, the total number of bacteria in the dust collection, and the total number of fungi were detected. Results The average daily average value of pollutants in the air-conditioning air supply system was 13.2 mg / m2 for the dust of the pipeline, 297 cfu / m3 for the bacteria and 269 cfu / m3 for the fungi. The pollution degree of the air- For serious pollution, a hotel air-conditioning duct system for medium pollution. Conclusion TENZHOU City, central air conditioning and ventilation system there are hidden dangers of pollution, from the perspective of safeguarding the economic development and public health perspective, we must strengthen the centralized air conditioning and ventilation system supervision.
