摘要： 以长沙一外呼吸玻璃幕墙为例，建立了热工网络模型和数学模型。采用Window6.2 和EnergyPlus2.2软件模拟计算了不同幕墙的综合传热系数和设计日冷热负荷。分析了玻璃类型和通风腔宽度对幕墙建筑负荷的影响，并进行了能耗和经济可行性分析。 关键词： 外呼吸玻璃幕墙 综合传热系数 冷热负荷 玻璃类型 通风腔宽度 Thermal characteristics and energy consumption analysis of external respiration double-skin facades By Wang Hanqing★, Chen Yu, Kou Guangxiao and Wang Zhiyong Abstract Taking an external respiration double-skin facade building in Changsha as an example, establishes a thermal network model and a mathematical model. Simulates and calculates integrated heat transfer coefficients and design cooling and heating loads for different facade buildings by Window6.2 and EnergyPlus2.2 softwares. Analyses the influences of glass type and airspace width, and energy consumption and economic feasibility.
