| 中文摘要 | 本文首先介绍了水平外百叶体系透过模型的计算原理及方法,通过此方法得到了水平外百叶的遮蔽系数,并与国内外几个软件计算的结果进行了比较验证。而后计算分析了水平外百叶的间距系数、偏转角度、表面材料反射率等参数对百叶遮蔽系数的影响情况,并给出了几个不同气候分区下典型城市的百叶遮蔽系数结果。最后以1栋大窗墙比办公建筑为例,比较了《公共建筑节能设计标准》(GB 50189-2005)推荐的百叶遮蔽系数计算方法和本文中提到的百叶遮蔽系数计算方法对建筑负荷的影响情况,指出了传统方法中的不足,给出了改进的方法。; In this paper,the calculation principles and methods of the permeation model for horizontal louvers were firstly introduced,the shading coefficient was obtained and the simulated results were validated by comparing with other results of several kinds of shading design softwares.And then the influence of some parameters,such as width,lean angle and reflectivity of material,on the shading coefficient was analyzed,also the results of shading coefficient of some typical cities in different climate areas were given out.At last,taking an office building with large window-wall ratio as an example,the impacts of two kinds of methods for calculating the shading coefficient on the building load were compared,one was recommended by Design Standard for Energy Efficiency of Public Buildings(GB 50189-2005),the other was proposed by this paper,the shortage of the former method was pointed out and the improvement advice was concluded. |
