外呼吸双层通风玻璃幕墙热工性能模拟分析

Simulation and analysis of thermal performance of external respiration double skin facade

对某建筑外呼吸双层通风玻璃幕墙内的速度场和温度场进行了模拟分析。讨论了遮阳设施、空气层宽度等因素对综合传热系数的影响。分析比较了外呼吸双层玻璃幕墙建筑和四种单层玻璃幕墙建筑的供暖空调能耗。结果表明,外呼吸双层通风玻璃幕墙是一种节能的生态建筑围护结构形式。

Simulates and analyses the velocity and temperature fields inside the external respiration double skin facade of a building. Discusses the influences of the shading and airspace width on the integrated heat transfer coefficient. Compares the heating and cooling energy consumption of buildings applying external respiration double skin facade with that of buildings applying four single glazing curtain walls. The results show that the external respiration double skin facade has a superior energy efficiency potential and is one of the ecological building envelops.
