目的为了解浙江省集中空调通风系统卫生状况,以及公共场所集中空调卫生检测中存在的问题。方法对全省11个地市及义乌市的190家公共场所集中空调通风系统卫生指标进行检测。结果旅店、商场、医院、娱乐场所、写字楼5类公共场所检测指标均合格的占39.47%;10项指标的检测合格率为88.98%,其中送风中细菌总数和真菌总数合格率较低,分别为67.89%和78.95%,其余指标合格率均在80%以上,仅送风中β-溶血性链球菌合格率为100%。表明集中空调通风系统存在一定程度的污染。结论集中空调通风系统污染情况不容乐观,公共场所应做好空调系统的日常卫生管理和清洗消毒工作,保证空调系统运行期间室内空气品质。
Objective To understand the health condition of central air conditioning and ventilation system in Zhejiang Province and the problems existing in the hygienic testing of central air conditioners in public places. Methods The health indicators of central air conditioning and ventilation system in 190 cities and 11 public places in Yiwu City were tested. Results The detection indexes of five public places in hotels, shopping malls, hospitals, entertainment venues and office buildings all accounted for 39.47%; the passing rate of 10 indexes was 88.98%, of which the total number of bacteria and the total number of fungi in air supply were lower, respectively 67.89% and 78.95%, the remaining indicators pass rate of more than 80%, only air supply β-hemolytic streptococcus pass rate of 100%. This shows that there is a certain degree of pollution in the centralized air conditioning and ventilation system. Conclusion The pollution of centralized air conditioning and ventilation system is not optimistic. Public health management and cleaning and disinfection of air conditioning system should be well done to ensure the indoor air quality during the operation of air conditioning system.
