【英文篇名】 Field test method of air leakage through installed exterior windows in residential buildings 【作者中文名】 徐选才; 梁晶; 【作者英文名】 Xu Xuancai Liang Jing China Academy of Building Research; Beijing; China; 【作者单位】 中国建筑科学研究院; 北京市建筑设计研究院; 【文献出处】 暖通空调, Heating Ventilating 外窗; 气密性能; 现场检测; 惯常检测法; 不确定度; 【英文关键词】 residential building; exterior window; air-tightness performance; field test; commonly-used test method; uncertainty; 【摘要】 从不同操作者采用惯常检测法对同一个外窗窗口气密性能现场比对检测结果的分析入手,对惯常检测法进行了研究。结合我国居住建筑外窗特征和现有检测设备的情况,提出了综合不确定度20%的控制目标,明确规定了检测过程中室外风速和附加渗透风量的限值及各分项检测参数的不确定度控制指标。 【英文摘要】 The commonly-used test method is questioned through the comparison of two sets of data yielded respectively in the field tests of air leakage through the same installed exterior window by different testers.Combining with the features of exterior windows generally used in residential buildings and the condition of current measuring apparatus,puts forward the overall uncertainty of 20% as a control object, and specifies the limited values of outdoor wind velocity and additional air leakage and the uncertainty...
