摘要
目的通过分析公共场所集中空调通风系统抽检结果,探讨影响集中空调通风系统合格率的因素。方法随机抽取合肥市22个使用集中空调通风系统的公共场所,检测空调送风中可吸入颗粒物(PM_(10))、细菌总数、真菌总数、新风量、风管内表面细菌总数、风管内表面真菌总数、空调风管内表面积尘量、冷却水及冷凝水嗜肺军团菌。检测及评价依据《公共场所集中空调通风系统卫生规范》(WS394—2012)。结果检测22家公共场所,总合格率为77.27%,其中17家场所检测指标合格率100.00%。13家宾馆酒店,10家合格,合格率为76.90%,其他场所合格率为77.78%,差异无统计学意义(P_(Fisher)=1.000)。空调送风中真菌总数合格率最低,为77.27%,其次为空调送风中细菌总数,合格率为81.82%,空调风管内表面细菌总数及真菌总数合格率均为95.45%,其余指标合格率均为100.00%。结论合肥市集中空调通风系统抽检合格率不容乐观,空调送风微生物污染是影响合格率的主要因素。
