【摘要】：为了更加科学合理地动态调整双层皮幕墙(DSF)内置遮阳百叶的角度,满足自然采光和节能的双重需求,建立了受遮阳百叶倾角影响的室内综合得热量与平均采光系数的数学模型,通过对模拟结果的标准化处理和线性加权求和方法,建立了DSF内置遮阳百叶倾角评价模型.以长沙地区某建筑南向DSF为例,详细介绍了自然通风工况下,8:00至18:00时间段内,晴天及阴天典型日该双层皮幕墙百叶倾角评价模型的构建过程.通过模拟分析发现,长沙夏季晴天DSF遮阳百叶最佳倾角为82°,最佳倾角范围为73°~90°;长沙夏季阴天DSF系统遮阳百叶最佳倾角为0°,最佳倾角范围为0°~36°.
[Abstract]:In order to more scientifically and reasonably adjust the angle of sunshade shutter built in double-layer curtain wall DSFs, and to meet the dual demand of natural lighting and energy saving, a mathematical model of indoor comprehensive heat gain and average daylighting coefficient influenced by sunshade shutter inclination angle was established. Based on the standardization of the simulation results and the linear weighted summation method, the evaluation model of the inner-shaded louver inclination of DSF is established. Taking a building in Changsha area as an example, this paper introduces in detail the construction process of the evaluation model of the double layer curtain wall's hundred leaf inclination angle in the period of 8: 00 to 18:00 under natural ventilation condition, on sunny and cloudy typical days. Through simulation analysis, it is found that the optimum dip angle of DSF sunshade 100 leaf is 82 掳and the optimum inclination range is 73 掳~ 90 掳on sunny day in Changsha summer, and the optimum dip angle is 0 掳and 36 掳in DSF system on overcast day in Changsha summer.
