Discussion on indoor particulate matter (PM2.5) pollution control technologies of schools in cold regions

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.
