寒冷地区中小学校控制室内细颗粒物(PM2.5)的思考
Discussion on indoor particulate matter (PM2.5) pollution control technologies of schools in cold regions
摘要：
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。
Abstract：
Analyses the characteristics of the primary and secondary school buildings, compares the filtration efficiency of the national standard with the European standard, summarizes the calculation method of stable state air circulation volume with self circulation purifier design in the classroom to meet the purification requirement. According to the filter efficiency and indoor air purification target, calculates the given data, analyses and summarizes the technical characteristics of the PM2.5 purification in the classrooms. Explores the technical measures for the air purification of primary and secondary schools, studies and analyses the possible technical schemes adopted in the primary and secondary schools.
