渗透通风建筑室内颗粒物的污染特征
Pollution characteristics of indoor particle matter at infiltration ventilation building
摘要
Abstract
Pollution characteristics in infiltration ventilation room was analyzed in Changzhou through establishing both the mathematical model of particle penetration rate with air exchange rate and the mass balance equation of particulate matter.The accuracy of those models were also tested and verified by experiments.The results indicate that the penetration rate of particle with diameter of 0.5,1.0,2.5 μm and PM2.5 were increased with air exchange rate,and the penetration rate of PM2.5 increased from 70％ to 88％,increasing by 25.7％ when the air exchange rate increased from 0.2 times per hour to 0.5 times per hour.The clean air delivery rate value of air cleaner was 152 m3·h-1,which attenuated 52.5％ compared to the value of 320 m3·h-1 in test chamber conditions using cigarette smoke as the pollutant source.关键词
