武汉高校公共教室夏季热环境的实测研究

在对武汉某高校公共教学楼内多个公共教室进行室内热环境调查和实测的基础上,选择一间实验教室进行对比测试,测试结果证明该实验方法可靠。通过对公共教室和实验教室实测数据的分析和比较,指出无法进行夜间通风和不适宜的开窗方式是公共教室热环境不佳的主要原因。最后根据武汉地区气象资料,结合高校教学时段提出加强通风散热,缩小室内外温差以提高公共教室自然通风效率不仅能够改善公共教室室内热环境,也是减少空调能耗的关键。

Field Study on Summer Thermal Environment of University Public Classroom in Wuhan

A field study is carried out on several public classrooms in university campus in Wuhan and one experimental classroom is chosen as a control. The experimental method is demonstrated as reliable. Based on analysis and comparison of data, we propose that without night ventilation and inappropriate window design are the main reasons of poor indoor thermal environment. Combined with the meteorological data in Wuhan and teaching time in university, we present that the key to reduce energy of air conditioning and improve indoor thermal environment is to raise ventilation efficiency by narrowing temperature difference, enhancing ventilation and distributing heat.
