带走廊玻璃幕墙建筑的日射负荷计算分析

为带走廊玻璃幕墙建筑中的日光传递过程建立了物理模型,用级数求和的方法对内部房间的日射得热进行了分析,对房间墙体外表面扰量的等效温度和通过幕墙逃逸回外界的辐射量进行了计算.结合不同的建筑实例进行了分析,结果表明,透过幕墙的太阳辐射可能会在内部房间的墙壁外侧形成一个较大的扰量,不能简单地忽略;透过幕墙进入建筑内部的太阳辐射只有一部分会转化为走廊空间的空调负荷,计算时需对此加以分析,否则会时建筑物的节能不利.

Analysis on the Cooling Load Calculation of A Particular Kind of Glass Curtain Wall Buildings

The physical model of the solar radiation procedure in a particular kind of building was developed,in which there is a corridor between the glass curtain wall and the inner brick wall.The impact of the solar radiation on the corridor's and the inner room's heat gains was analyzed,and two calculating formulas based on the analysis of an infinite series were obtained.Several typical cases were listed,and the results show that the solar radiation may have notable effect on the inner room and only a part of rad...
