室内通风方式对PM2.5浓度的影响

The Effect of Ventilation Patterns on PM2.5 Concentration in Door

参与空气质量评价的主要污染物为细颗粒物PM2.5,大气中PM2.5不仅影响气候和空气质量,而且严重危害人体健康。PM2.5等细颗粒物是大气中主要污染物之一,PM2.5对正处于发育期的学生危害极大,因此良好的教室内空气品质对学生的健康成长有着重要的意义,而教室通风方式对室内PM2.5的质量浓度分布有着直接关联。为探究郑州学校教室内PM2.5浓度长期变化及其影响因素,本研究运用I/O值和线性回归分析法,对2018~2019年均教室内PM2.5浓度网格化数据进行分析。并结合河南省郑州市某中学教室进行了实测,以探求自然通风与新风系统两种不同的通风方式对室内PM2.5浓度的影响。

The main pollutants participating in the air quality assessment are fine particulate matter PM2.5.PM2.5 in the atmosphere not only affects the climate and air quality,but also seriously endangers the health of the population.Fine particles such as PM2.5 are one of the main pollutants in the atmosphere,and PM2.5 is extremely harmful to students who are in the developmental stage,so good air quality in the classroom has great significance to the healthy growth of students.And classroom ventilation is directly related to the indoor PM2.5 mass concentration distribution.In order to explore the long-term spatial and temporal changes of PM2.5 concentration in classrooms of Zhengzhou schools and its influencing factors,this study used I/O values and linear regression analysis to analyze the gridded data of average PM2.5 concentration in classrooms from 2018 to 2019.In order to explore the influence of natural ventilation and fresh air system on indoor PM2.5 concentration,the experiment was carried out in a middle school classroom in Zhengzhou,Henan Province.
