目的分析克拉玛依独山子区集中空调系统在供冷期和供热期送风口空气质量状况及差别。方法 2011~2012年对克拉玛依市独山子区7家公共场所的集中空调系统进行监测,检测集中空调系统送风口湿度、温度、空气的细菌总数和真菌总数、β-溶血性链球菌、金黄色葡萄球菌、有溶血环葡萄球菌指标,利用Excel和SPSS进行数据统计分析。结果供冷期与供热期空气合格率差异有统计学意义(P<0.01),供冷期空气合格率为83.45%~85.59%,供热期空气合格率为92.86%~94.12%,供冷期比供热期不合格率高2~3倍。金黄色葡萄球菌检出率为4.44%~5.08%,有溶血环葡萄球菌检出率为13.28%~19.26%,β-溶血性链球菌未检出。结论供冷期第二、三季度集中空调系统空气质量卫生安全隐患高。
Objective To analyze the condition and difference of the air quality of the air supply in the Karamay Dushanzi district central air-conditioning system in the cooling period and the heat supply period. Methods From 2011 to 2012, the central air-conditioning systems in seven public places in Dushanzi District of Karamay were monitored to detect the total number of bacteria and fungi in the humidity, temperature and air at the outlet of centralized air-conditioning system, β-hemolytic streptococcus and golden yellow grape Cocci, Staphylococcus aureus index, using Excel and SPSS for statistical analysis of data. Results There was a significant difference in pass rate of air between cooling period and heating period (P <0.01), passing rate of air in cooling period was 83.45% -85.59%, air passing rate in heating period was 92.86% -94.12% Period than the heating failure rate of 2 to 3 times. Staphylococcus aureus detection rate was 4.44% ~ 5.08%, the detection rate of Staphylococcus aureus was 13.28% ~ 19.26%, β-hemolytic streptococcus was not detected. Conclusion In the second and third quarters of the cooling period, the air quality and health risks of the centralized air-conditioning system are high.
