分析了中小学校建筑的特点,对比了国家标准空气过滤器和欧洲标准空气过滤器的过滤效率,归纳出室内设置自循环净化器、满足教室内洁净度要求所需循环风量的稳定工况的计算方法。并针对不同过滤器的过滤效率以及不同教室室内浓度控制目标进行计算,分析、总结中小学校教室控制室内PM2.5浓度的技术特点。探索了适用于中小学校空气净化的技术措施,并对中小学校可能采用的技术方案进行了研究和分析。
Analyzes the characteristics of primary and secondary school buildings, compares the filtering efficiency of national standard air filters and European standard air filters, and summarizes the calculation of stable operating conditions for indoor circulating self-recirculating purifiers and the required circulating air volume to meet the cleanliness requirements in classrooms. method. In addition, the filter efficiency of different filters and the indoor concentration control targets in different classrooms were calculated, and the technical characteristics of the PM2.5 concentration in classrooms of classrooms in primary and middle schools were analyzed and summarized. It explored the technical measures applicable to air purification in primary and secondary schools, and conducted research and analysis on the possible technical solutions adopted by primary and secondary schools.
