摘要
目的应用模糊隶属方法评价公共场所集中空调通风系统的卫生质量。方法应用模糊数学的隶属度理论方法,抽取金华市15家大型公共场所的集中空调系统,对其卫生相关指标进行检测。按照《公共场所卫生综合评价方法》(WS/T 199—2001)进行模糊综合评价。结果公共场所15家集中空调系统卫生质量合格率为53.30%,其中相关指标检测合格率显示,送风细菌总数、送风真菌总数和送风β-溶血性链球菌及冷却水冷凝水中嗜肺军团菌均为100.00%,风管内表面细菌总数为93.33%,风管内表面真菌总数为86.67%,送风PM10为86.67%,风管内表面积尘量为80.00%。集中空调系统卫生质量经模糊隶属度评判,Ⅰ级(良好)的有13家,Ⅱ级(合格)有1家,Ⅳ级(很差)有1家,其中14家卫生质量模糊综合指数均<0.5。结论金华市公共场所集中空调通风系统卫生质量总体尚可,与一般的公共场所合格率评价不尽相同。
Objective To assess the hygienic status of the central air conditioning ventilation system in public places by fuzzy comprehensive evaluation method.Methods According to the comprehensive evaluation method of public place （WS /T 199—2001）,a fuzzy comprehensive evaluation method was applied to evaluate central air conditioning ventilation systems in 15 large public places of Jinhua City.Results The qualified rate of central air ventilation system was 53.30%, and the qualified rates of total number of bacteria,the fungi,β-hemolytic streptococcus in air blow and Legionella bacteria in the cooling water all reached 100.00%.At the same time,the qualified rate of bacteria,fungi and dust volume in internal surface of pipe were 93.33%,86.67% and 80.00% respectively.The qualified rate of PM10 was 86.67%. Among 15 central air conditioning ventilation systems,13 systems were evaluated as level Ⅰ,and the other two was as level Ⅱand Ⅳ respectively.TAAlso,14 evaluated units got the fuzzy comprehensive indexes of central air ventilation less than 0.5.Conclusion The hygiene status of central air conditioning ventilation system in Jinhua is acceptable,and the management of hygiene quality should be strengthened.
