西门子上海中心双层幕墙的通风节能技术分析

Analysis of Ventilation and Energy Saving Technology of Double Vurtain Wall in Siemens Shanghai Center

西门子上海中心双层幕墙系统设计整体整洁、透明大方、节能效果明显,该幕墙分格尺寸达到了2800mm×4000mm,设计过程中以计算机模拟为基础,技术论证计算为指导,过幕墙整体的通风构造设计、幕墙构件自身的断热设计及幕墙中间腔体的遮阳帘设计,幕墙整体的传热系数达到了1.8W/m^2·K,该双层幕墙节能性、舒适性均达到了设计初始要求。

Design of double skin facade system of Siemens Center Shanghai overall clean, transparent and generous, energysaving effect significantly, the curtain wall divided into lattice size reached 2800mm ×4000mm. Design process by computer simulation based, technology demonstration calculation as a guide, the overall curtain wall ventilation structure design, curtain wall component itself off thermal design and curtain walls in the middle of the cavity of the sunshade curtain, curtain wall overall heat transfer coefficient reached 1.8W/（m2 k）.The double-layer curtain wall energy-saving, comfort to initial requirements.
