辐射空调房间内围护结构表面之间的角系数，以及人体表面与室内维护结构表面之间的角系数，是计算室内辐射热交换的基本参数。目前，有关人体、辐射板、门、窗等表面和其它围护结构表面间的角系数通常较难求解，这里避开了采用传统的直接积分法求解角系数，而是利用对表面边界曲线的角系数积分公式，推导出了相互垂直以及相互平行情况下两矩形表面间的角系数表达式，其过程较为简单；同时把人体形状适当地简化为1个六面体固体，得到了人体与维护结构表面之间的角系数。所得结论不受围护结构表面大小及相对位置的限制，可以有效地求解与人体、辐射板、门、窗等表面相关的角系数。

Angle factors between enclosure structural surfaces , or between human body and enclosure structural surfaces are the basic parameters to calculate radiant heat transfer in a radiant air‐conditioned room .At present ,the angle factors between the human body ,radiant panels ,windows and doors are usually quite difficult to solve .Therefore ,we derived the angle factor expressions of two rectangular surfaces in the positions both mutual perpendicular and mutual parallel by using curve integral formula of angle factor ,instead of using conventional surface integral formula .Meanwhile ,angle factors between human body and enclosure structural surfaces by simplifying a seated person as a rectangular solid were acquired .The results were shown to be efficient and practical ,and were free from the limitation of envehpe sizes and relative positions .
