| 摘 要： | 为准确了解建筑节能窗的传热特性,采用数值模拟方法对典型节能窗的玻璃系统和窗框系统传热维数进行分析。结果表明:玻璃系统为一维传热过程,水平窗框系统为二维传热过程,竖直窗框系统则为三维传热过程。在竖直窗框系统中三维传热模拟结果与二维传热模拟结果相差6%以上。

| Abstract: | In order to accurately analyze heat transfer characteristics of building energy-saving window,analysis of dimensions of glass systems and frame systems is carried out typical energy-saving windows using numerical methods.Result shows that heat transfer process is one-dimension in glass systems,two-dimension in horizontal frame systems and three-dimension in vertical frame systems. In numerical simulation of vertical frame system heat transfer process,results of three-dimensional way and two-dimensional way differ by more than 6%. |
