摘　　要：目的了解惠州市公共场所集中空调通风系统的卫生状况,为今后卫生管理工作提供科学依据。方法按照《公共场所集中空调通风系统卫生规范》(WS 394-2012)对惠州市5类106家公共场所的集中空调通风系统进行卫生学调查,采用卡方检验进行统计分析。结果不同公共场所集中空调通风系统监测项目中,风管内表面积尘量、真菌总数、细菌总数的合格率分别为87.7%、87.6%、89.1%;送风中PM10、细菌总数、真菌总数、β-溶血性链球菌的合格率分别为100%、90.9%、92.6%、100%;冷凝水和冷却水嗜肺军团菌总检出率分别为12.8%和22.4%。KTV的风管内表面和送风的卫生状况最差,集中空调通风系统嗜肺军团菌污染情况亦比较严重。结论惠州市公共场所集中空调通风系统卫生管理不完善,卫生指标未全部达标,其中卫生状况最差的场所是KTV,应加强空调系统的运行管理,提高空调环境卫生状况,促进人群健康。Objective To investigate and analyze the hygienic status of central air conditioning ventilation sys- tems in public places of Huizhou city, and to provide the basis for standardizing sanitary management. Methods The hygienic statue of 5 types of central air conditioning ventilation system in 106 public places were investigated according to the Hygienic Standards for Centralized Air Conditioning Ventilation Systems in Public Places（WS 394 -2012）. Results the qualified rate of the dust, total fungi and the total bacteria counts in the inner surface of pipes was 87.7% ,87.6% and 89.1% , respectively; the qualified rate of PM10, total fungi, total bacteria counts and 13 - hemolytic streptococci in ventilating air was 100% , 90.9% , 92.6% and 100% , respectively. The quali- fied rate of condensed and cooling water was 12. 8% and 22.4% , respectively. The hygienic condition in KTV was the worst and the contamination of legionella pneumophila was serious. Conclusions Sanitary management of cen- tral air conditioning ventilation system in public buildings in Huizhou city was somewhat not fully in place, the hy- gienic condition in KTV was the worst, and the hygienic status did not reach expected standards. Reinforcing the sanitary management and improving the hygienic status of central air conditioning ventilation system in public places were very important to help promoting people＇s health.
