摘要
玻璃幕墙及大面积玻璃窗在现代建筑中有许多应用。为了减少夏季的太阳辐射得热或冬季的失热,这些结构可以设计为双层的并在双层的空腔中进行通风,这种结构称为双层皮通风围护结构。回顾了该结构的热特性模型,该热特性模型从建模方法上基本可以分为CFD模型、集总参数模型、热与气流网络模型、控制体积模型、区域模型等,分析了这些模型的特点及应用。后4种模型可以与常规建筑能耗模拟软件集成,进行房间或整个建筑的能耗分析,并对该结构的优化控制进行分析。
Curtains and windows with large glass are utilized widely in contemporary buildings. These curtains or windows are designed as double-skin with aiuTow passing through, to reduce solar radiation in summer and heat loss in winter. The structures are called doubleskin ventilated building envelope due to it acting as envelope. The development of thermal models for these structures which may be categorized as CFD model, lumped model, thermal and airflow network model, control volume model, zonal model etc, based on modeling approach. Their characteristics and applications are expounded in details. The later four models can be integrated with conventional building energy soft-ware for energy performance analysis or control analysis of the room or the whole building which utilized this double-skin ventilated building envelope.
