Hygienic Status of Centralized Air Conditioning Ventilation System in Public Places of JiNan City during 2011-2015

摘要

摘要:
目的掌握济南市公共场所集中空调通风系统卫生状况。
方法按照《公共场所集中空调通风系统卫生规范》对2011年-2015年度济南市127家公共场所集中空调通风系统进行检测和分析。
结果济南市公共场所集中空调通风系统合格率为51.2%，不同年份集中空调合格率差异有统计学意义（χ²=417.3，P<0.01）。集中空调送风中细菌总数、真菌总数合格率分别为71.2%、85.4%；风管内表面积尘、细菌总数和真菌总数的合格率分别为98.4%、99.2%和100%；冷却塔冷却水嗜肺军团菌检出率为30%，菌型以LP1为主，占58.3%。
结论济南市公共场所集中通风系统卫生合格率较低，应加强对通风系统的清洗和管理。
