| 摘 要： | 辐射采暖方式由于具有舒适性、节能性等特点越来越广泛的被应用。为了能够确定辐射采暖房间内的热环境状况，必须对采暖房间各围护结构内表面间的辐射换热进行计算。反映两表面间相对位置的变量——角系数，是各表面间辐射换热计算的基础，其计算比较复杂。本文介绍了外围护结构有窗时角系数的计算方法，根据角系数的完整性、分解性及互换性原理推导出了其计算公式，给出了几种外窗尺寸下外围护结构对其余所有围护结构角系数值。

| Abstract: | Radiant heating is applied widely because of comfort and saving energy. In order to confirm the heat environment of room with radiant heating, the radiant heat among the inner surfaces of envelope must be calculated. Angel factor is a variable of relative place, which is the basis of calculation of radiant heat among the surfaces. The calculation is relatively complex. The calculation method of angel factor when there are windows in outer envelops is introduced, the formulas are deduced according to the principle of integrality, resolvability and reciprocation of angel factor, and angel factor of envelop to other envelops for several dimensions of outer windows is supplied in this paper. |
