摘要
介绍了冬季双层皮幕墙(double skin facades,DSF)的两种运行模式。用能量平衡法模拟了这两种模式幕墙的热性能,然后介绍了通过DSF的得热量的计算方法;并用冷辐射系数法将得热量转化为室内负荷。以长沙地区某DSF为算例对其在冬季工况下的累计负荷进行了模拟,提出了一种优化的DSF冬季运行模式;计算结果表明该模式比封闭的DSF节能10%。
Two operating modes of DSF（ double skin facades）, in winter adopt energy balance method in heat exchange network to calculate the thermal performance of DSF were introduced. Then the caculation method of heat gains through the facade and converting the heat gains to an indoor heat load by cold radiation coefficient method were introduced. The total load of DSF in Changsha in winter condition was simulated. Results show that this opti- mal model is more energy-saving than the closed mode by 10 percent.
