【英文篇名】 Test and analysis of heat loss through open windows in heated residential rooms 【作者中文名】 李京美; 付林; 狄洪发; 【作者英文名】 Li Jingmei; Fu Lin and Di Hongfa Tsinghua University; Beijing; China; 【作者单位】 清华大学; 【文献出处】 暖通空调, Heating Ventilating 换气次数; 综合传热系数; 【英文关键词】 heat loss through open window; air change rate; integrated heat transfer coefficient; 【摘要】 分析了开窗对室内温度的影响,利用示踪气体法测试了冬季工况下开窗房间的通风换气次数。根据对7个住宅小区供热系统的测试结果,利用建筑围护结构综合传热系数计算得出了各个小区的开窗热损失。认为供热系统适量供热、室内温度保持在合理水平对减少开窗热损失至关重要。 【英文摘要】 Analyses the effect of windows opening on indoor temperature. Tests air change rate in rooms with windows opening using the tracer gas method. According to the test results of heating systems in seven residential quarters, calculates the heat loss through open windows using the integrated heat transfer coefficient of buildings. Thinks that adequate heat supply and proper indoor temperature is important to lowering heat loss through open windows.
