摘要
充足的新风量对于保证室内人员健康具有重要意义。中国高等学校学生公寓人员密度较高,主要依靠自然通风的方式获取新风,目前国内较为缺乏对这类建筑通风现状的研究。本文采用示踪气体法,以睡眠状态下的人体作为CO2的稳定释放源,对清华大学紫荆公寓夏季自然通风状况进行了测试,分析比较了公寓不同位置处房间通风状况的差异,研究了单侧通风条件下室内外温差与房间通风量之间的关系,进而对当前学生公寓通风情况的现状做出了评价并提出了改进建议。
Enough outdoor fresh air is important for people＇s health and indoor thermal comfort. At present, natural ventilation is the most common way to obtain outdoor fresh air in student dormitories in China. However, there is a lack of related studies. In this paper,in order to investigate the natural ventilation situation in student dormitories in Tsinghua University in summer, tracer gas method was used in a field testing. Students in sleep mode was considered as the stable emission resource of CO2. The discrepancy of ventilation state in the rooms which located in different positions was analyzed. Furthermore, the relationships between temperature difference of inside and outside and ventilation volume under single-side ventilation condition were discussed. Based on the analysis, the situation of natural ventilation in student dormitories was evaluated and the improved suggestions were provided.
