教室作为人员密集型建筑,室内环境的好坏不但影响学生的学习能力,也影响到教师的授课效率。本文通过对某高校冬季自然通风教室室内空气环境、光环境的现场实测,结合现场问卷调查,利用Matlab及Excel等数学工具对数据进行处理,得出室内光照度、PMV值、CO2浓度对学习效率的影响规律。结果表明,CO2浓度较室内光照度、PMV等参数对于学生学习效率的影响更大。针对这种情况,提出了改善措施,如在教室里设置CO2浓度传感器和信号灯、教学楼设置之初考虑当地主导风向以助于自然通风等。

As a personnel-intensive building, the indoor environment of classrooms affects not only the students' learning ability, but also the teachers' teaching efficiency. Through the in-field measurements and questionnaires of naturally ventilated classrooms of one university in winter and processing data with the mathematical tools such as Matlab and Excel, the influence of indoor lighting, PMV and carbon dioxide concentration on learning efficiency were eoncluded. The result shows that the carbon dioxide is a more important influent factor. And then, some improving solutions, such as setting CO2 concentration sensors and signal, lamps in the classroom, considering the dominant wind direction when designing the teaching buildings for helping natural ventilation etc, were put forward.
