济南某高校教室室内环境测试与问卷调查

在供暖季节对济南市某高校自然通风教室内的室内环境状况进行测试与调查,分别在上课阶段测量室内各参数并结合主观调查问卷,分析比较12月份与3月份由于温度变化所引起的开窗情况,室内CO2浓度变化以及通风换气对教室室内环境质量的影响规律,并探究其对学生热舒适及学习状况的影响。由测试结果分析得出,较冷天气下,很少有人会主动开窗通风,导致教室内通风量严重不足,CO2浓度超标,室内空气品质很差,基本上可以认为室内没有换气,通风量计算公式对于换气次数如此小的教室来说是不适用的,并且有38.9%的学生反应教室太闷时会打瞌睡。

Indoor Environment Measurement and Questionnaire Survey of a University Classroom in Jinan

The indoor environmental conditions in a natural ventilation classroom of a university in Jinan during the heating season was test and investigated,which measured indoor parameters and combined subjective questionnaires in the course of class.The window opening caused by temperature changes in December and March was analyze and compared.The effect of indoor CO2 concentration changes and ventilation on the indoor environmental quality of classrooms.Its impact on students’thermal comfort and learning conditions was explored.From the analysis of the test results,few people will actively open windows and ventilate in colder weather,this resulted in a serious shortage of ventilation in the classroom,excessive CO2 concentration,and poor indoor air quality,just as no ventilation in the room.The calculation formula for ventilation is not applicable to classrooms with such a small number of ventilations.38.9%of the students reacted to the classroom when they were too stuffy and would doze off.
