长江三角洲地区空调通风系统的细颗粒物室外设计浓度研究

Study on outdoor design concentration of fine particulate matter for air-conditioning and ventilation system in Yangtze River Delta

根据"中国空气质量在线监测分析平台"发布的2014—2016年细颗粒物(PM2.5)监测数据,在对长江三角洲主要城市PM2.5室外浓度日均值监测数据分析的基础上,研究"历年平均不保证天数"和数学归纳分析方法在确定PM2.5室外设计浓度值时的优缺点和适用性。并采用数学归纳分析方法拟合长江三角洲区域主要城市PM2.5室外设计浓度与年平均浓度之间的关系式,根据此关系式采用各城市的细颗粒物室外浓度年均值为参照值,可以快速确定建筑空调通风系统过滤器的PM2.5室外设计浓度。

Based on the monitoring data of fine particulate matter （PM2.5） from 2014 to 2016 published by China Air Quality Online Monitoring and Analysis Platform, the moni- toring data of PM2.5 daily concentration in the main cities of Yangtze River Delta are analyzed, and the advantages ＆ disadvantages and applicability of the methods of ＂non-guar- antee days over the years＂ and mathematical induction analysis in determining the outdoor design concentration value of PM2.5 are studied. The mathematical induction analysis method is used to fit the equation between outdoor design concentration of PM2.5 and annual mean concentration in the main cities. According to this equation, outdoor design concentration of PM2.5 of the building air-conditioning and ventilation system filter can be determined by the city＇s annual average concentration of fine particulate matter.
