公共场所集中空调通风系统污染状况调查与评价

目的调查评价公共场所集中空调通风系统污染状况,为卫生管理提供依据。方法采集集中空调通风系统送风管或送风口的积尘样品称重,并检测其细菌总数和真菌总数,依照《公共场所集中通风系统卫生规范》进行评价。结果40%的集中空调通风系统为中度污染,60%为重度污染,通风管道没有预留维修人口,通风管道内部从未清洗消毒。结论公共场所集中空调通风系统应加强卫生管理。

Investigation and evaluation of the contaminative situatyon of ventilation system of centralized air conditioners in public areas

obiective:In order to investigate and evaluate the contaminative situation of ventilationsystem of centralized air conditioners in public areas and therefore provide support for the hygienemanagement. Methods:The samples were taken from the ventilation system of centralized aircondition, and then what total count of aerobic bacterial and moss count were tested. To evaluate it by The Hygiene criterion of ventilation system of centralized air conditioners in public areas. Reaults: It shows that about 40% of the ventilation tubing system in centralized air conditioners weremoderately contaminated, while 60% were heavily contaminated. Conclusion: Hygienemah-gement should be reinforced on the ventilation system of centralized air conditioners in public areas.
