双层玻璃幕墙作为一种新型的建筑围护结构形式,近年来被广泛应用到各类建筑中,遮阳百叶位置和热通道宽度是影响双层玻璃幕墙热工性能的重要因素。本文以武汉地区某双层玻璃幕墙为例,利用ANSYS模拟软件中的Fluent模块对不同百叶位置和热通道宽度下的速度场和温度场进行模拟,模拟结果表明不同百叶位置和热通道宽度下的速度场和温度场有明显差异。本文还对夏季晴天工况下热通道内的温度进行测试,测试数据与模拟结果较为吻合,从而验证了模拟结果的可靠性。
As a new type of building envelope structure, double-glazed curtain wall has been widely used in various buildings in recent years. The location of shades and the width of hot aisles are important factors affecting the thermal performance of double-glazed curtain wall. In this paper, a double-glazed curtain wall in Wuhan was taken as an example. The velocity field and temperature field under different louver locations and hot aisle widths were simulated using the Fluent module in the ANSYS simulation software. The simulation results show that different louver locations and hot aisle widths There are obvious differences between speed field and temperature field. In this paper, the temperature of the hot aisle in sunny summer conditions is tested, and the test data are in good agreement with the simulation results, which verifies the reliability of the simulation results.
