目的评价奥帆赛期间空调系统污染的危害因素,确保签约酒店、奥帆基地各单体室内空气质量达标,为奥帆赛各客户群体提供高质量的工作环境。方法依据《公共场所集中空调通风系统卫生规范》(2006)对集中空调送风中细菌总数、真菌总数、β溶血性链球菌、PM10、冷却水中军团菌进行检测。采用《公共场所卫生综合评价方法》(WS/T199-2001),对奥帆赛相关单位集中空调送风品质进行模糊综合评价。结果82个送风口细菌总数、真菌总数均<500 cfu/m3,β溶血性链球菌均未检出,冷却水军团菌检出率11.1%。奥帆赛签约酒店、奥帆基地各单体建筑集中空调送风品质模糊指数均P<0.5。结论奥帆赛各签约酒店、奥帆基地各单体建筑集中空调送风卫生质量全部为I级。应对部分冷却水军团菌的检出引起足够的重视。
Objective To evaluate the hazards of air-conditioning system pollution during the Olympic Sailing Competition and ensure the indoor air quality of the contracted hotels and Olympic Sailing Base to meet the standards and provide a high-quality work environment for all customer groups of the Olympic Sailing Regatta. Methods According to “Hygienic Standard for Ventilation System of Central Air Conditioning System in Public Places” (2006), the total number of bacteria, total number of fungi, β hemolytic streptococcus, PM10 and Legionella in cooling water were measured in the air conditioners. Adopting the “Public Health Evaluation Method” (WS / T199-2001), this paper conducts a fuzzy comprehensive evaluation on the air quality of the air-conditioners in relevant units of the Olympic Sailing Regatta. Results The total number of bacteria in 82 outlets and the total number of fungi were all less than 500 cfu / m3. None of β-hemolytic streptococcus was detected, and the detection rate of Legionella pneumophila was 11.1%. Olympic Regatta signing hotels, Olympic Sailing base of air-conditioning units of all buildings air quality fuzzy index P <0.5. Conclusion All the Olympic Sailing Tournament contracted hotels, Olympic Sailing base of the air-conditioned central air-conditioning all the air quality of health I level. Response to the detection of some cooling water Legionella caused enough attention.
