摘要
对北京某大厦的外呼吸式双层玻璃幕墙采用CFD模拟的方法,建立了矩形三维模型及设立边界条件,对热通道内的温度场和速度场进行模拟分析。通过改变热通道宽度、进出风口风速、进出风口高度等因素,分析其对双层玻璃幕墙系统热工性能的影响。得出最佳的通风方式和设计尺寸,对玻璃幕墙的结构形式和通风方式进行优化,以减少玻璃幕墙的建筑能耗。
Taking a building in Beijing as a model for analysis,this paper make numerical analysis about the velocity and temperature field of its double skin facade system by the method of CFD,build a rectangular three-dimensional model and establish the boundary conditions. Additionally,research on the thermal effect of double skin facade system is carried out by means of switching profiles like the width of heat passage,height and wind velocity of inlet and outlet. The purpose is to optimize the structure and ventilation method of skin facade system in optimum scale in order to facilitate energy conservation in buildings.
