摘　　要：因教室人员密集,PM_(2.5)、CO_(2)经常超标,教室内学生的学习、健康受到一定程度的影响.建立了室内污染物优化控制模型,对教室采用新风净化系统和空气净化器系统加开窗通风两种方式控制室内PM_(2.5)和CO_(2).首先在供暖季室外空气质量为中度污染情况下,模拟出天津某高校空气净化器系统在不同开窗方式及净化器位置情况下的室内PM_(2.5)和CO_(2)变化情况,得出空气净化系统在教室开侧窗,空气净化器安装在外墙旁侧时系统对PM_(2.5)和CO_(2)控制效果最好.然后模拟了在不同室外污染等级的情况下,教室采用新风净化系统和空气净化器系统加开窗通风两种方式的室内PM_(2.5)和CO_(2)的分布状况,通过对比室内污染物分布状况来研究两种净化方式对室内空气质量的控制效果.Due to crowded classrooms,PM_(2.5) and CO_(2) often exceed the standard,which affects students′learning and health to a certain extent.In this paper,an optimization control model of indoor pollutants was established,and the indoor PM_(2.5) and CO_(2) concentrations were controlled by two ways:fresh air purification system and air purifier system plus window ventilation.In this paper,under the condition of moderate outdoor air pollution in the heating season,the indoor PM_(2.5) and CO_(2) concentration changes of air purifier system in a university in Tianjin were simulated under different window opening methods and purifier positions.It is concluded that the air purification system has the best control effect on PM_(2.5) and CO_(2) concentration when the air purifier is installed on the side of the outer wall and the side window is open in the classroom.Then,the indoor PM_(2.5) and CO_(2) concentration distribution of classrooms using fresh air purification system and air purifier system plus window ventilation were simulated under different outdoor pollution levels.The control effect of the two purification methods on indoor air quality was studied by comparing the distribution of indoor pollutants.
