目的通过监测七类不同场所集中空调系统,为独山子区集中空调系统提出卫生安全预警,并为执法部门和管理经营都提示管理重点和方向。方法经过两年的连续监测,利用EXCELL和SPSS数据统计,分析独山子七类环境场所不同类型空调系统的卫生状况;分析温度、湿度、季节等条件与空调系统空气质量的相关性;分析致病菌检出率与空气质量、湿度、温度、积尘量的关联性。结果空气合格率77%,就医和住宿场所合格率最低为53.0%和39.1%,文化消费场所合格率最高为97.1%,第二、三季度合格率高于第一、二季度,温度26℃~28℃时各项指标不合格率较高,湿度(RH)25%~35%时,各项指标不合格率较高。结论第二、三季度是监测重点时间,25 m以下建筑高度积尘量检测值高,10 m~25 m空气微生物检出值高。
Objective By monitoring seven kinds of centralized air-conditioning systems in different places, the Dushanzi district central air-conditioning system proposed hygiene and safety warnings and prompted key points and directions for law enforcement departments and management. Methods After two years of continuous monitoring, the data of EXCELL and SPSS were used to analyze the hygienic status of different types of air-conditioning systems in Dushanzi seven environmental sites. The correlation between temperature, humidity, seasons and air-conditioning system air quality was analyzed. Detection rate of bacteria and air quality, humidity, temperature, the amount of dust accumulation. Results The passing rate of air was 77%, the lowest passing rate of medical treatment and accommodation was 53.0% and 39.1%, the highest pass rate of cultural consumption places was 97.1%, the second and third quarters pass rate was higher than the first and second quarters, the temperature was 26 ℃ ~ 28 ℃ when all indicators of high failure rate, humidity (RH) 25% to 35%, the indicators of a higher failure rate. Conclusions The second and third quarters are the key monitoring time. The detection value of dust accumulation at building height below 25 m is high, while the detection value of air microorganisms in 10 m ~ 25 m is high.
