住宅室内细颗粒物质量浓度及预测研究

选取哈尔滨某住宅,监测室内(以客厅为主要研究对象)细颗粒物质量浓度与人员活动情况,分析外窗渗透、外窗渗透+厨房炊事条件下客厅细颗粒物质量浓度的变化.建立室内细颗粒物质量浓度预测模型,结合实测数据对预测效果进行验证.实测结果表明:总体上客厅细颗粒物质量浓度均低于室外,且客厅细颗粒物质量浓度与室外细颗粒物质量浓度的变化趋势...

Study on Mass Concentration and Prediction of Indoor Fine Particulate Matter in Residential Buildings

A residence in Harbin was selected to monitor the mass concentration of indoor(taking the living room as the main research object) fine particulate matter and personnel activities, and analyze the changes in mass concentration of fine particulate matter in the living room under the conditions of external window penetration and external window penetration + kitchen cooking. The prediction model for mass concentration of indoor fine particulate matter was established, and the prediction effect was verified combined with the measured data. The measured results show that in general, the concentration of fine particles in the living room is lower than that outdoors, and the change trend of the concentration of fine particles in the living room is consistent with that outdoors. However, there is a certain lag in the change of the mass concentration of fine particulate matter in the living room, and the lag time is about 2 h. High-intensity cooking activities(especially stir-frying) are the main influencing factors leading to the increase in the mass concentration of fine particulate matter in the living room. Only under the condition of external window penetration, compared with the measured results, the relative error range of the predicted results is from-8.68% to 6.35%,and the predicted results are relatively ideal. Under the condition of external window penetration + kitchen cooking, compared with the measured results, the relative error range of the predicted results is from-13.99% to 25.60%,and the predicted results are not very ideal. In order to make the predicted results closer to the reality, the time step should be shortened.
