目的了解2013年大连市公共场所集中空调卫生状况。方法按《公共场所集中空调通风系统卫生规范》对大连市20家公共场所集中空调卫生状况进行监测。结果 2013年大连市公共场所集中空调通风系统总体合格率为60.00%。其中,积尘中的细菌总数合格率最高(100.00%),真菌总数合格率最低(81.39%),差异有统计学意义(P<0.05);星级宾馆送风中细菌总数与真菌总数合格率与大型商场超市相比,差异均有统计学意义(P<0.05)。与2012年相比,2013年送风中可吸入颗粒物合格率显著提高。结论 2013年大连市公共场所集中空调卫生状况总体上不容乐观,需要进一步提高。
Objective To understand the health status of central air conditioning in public places in 2013 in Dalian. Methods The health condition of central air conditioning in 20 public places in Dalian was monitored according to the Hygienic Standard for Central Air Conditioning and Ventilation System in Public Places. Results In 2013, the overall passing rate of centralized air conditioning and ventilation system in public places in Dalian was 60.00%. Among them, the total number of bacteria in the dust was the highest (100.00%), the lowest was the total number of fungi (81.39%), the difference was statistically significant (P <0.05). The total number of bacteria and the total number of fungi Compared with the large shopping malls, the differences were statistically significant (P <0.05). In 2013, the passing rate of respirable particulate matter in air was significantly higher than in 2012.
