摘要
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 To monitor central air conditioning systems in 7 different places, so as to give early warning and direc- tion of law enforcement and management in Dushanzi area. Methods Based on data of two - year continuous monitoring, EX- CELL and SPSS were employed to analyze the sanitary condition of the air conditioning systems of different environments in Dus- hanzi area. The correlation between temperature, humidity, season and air quality of air conditioning system, as well as the cor- relation between pathogen detection rate and the temperature, humidity, air quality, the amount of dust were all analyzed. Re- sults The total air qualified rate was 77% , and the lowest qualified rate of air was 39.1% in aceoomdations, followed by 53.0% in hospitals. Cultural venues had the highest qualified rate, reaching 97.1% , and those of the third quarter and the fourth qurter were higher than the first and the second quarter. Low qualified rates of various infieators were found at mperature ef 26 ℃ - 28 ℃ and humidity （RH） of 25% - 35%. Conclusion The second and the third quarter are the key monitoring season, building height under 25 m had large quantity of dust, and those between 10 m N 25 m had high microbial detection rate in air.
