摘　　要：用CFD方法研究遮阳位置对双层幕墙传热性能的影响.模拟结果表明,遮阳位置对内层中空玻璃的外表面温度有很大影响,由于遮阳位置不同,可导致内层中空玻璃的外表面温度最大相差2.7～3.5℃.遮阳位置距离外层玻璃内侧50～125 mm时,内层中空玻璃的外表面温度相对较低.另外,遮阳位置对空腔内部的温度分布影响也很大.Using the method of CFD simulation, the essay analyzes the influence of sunshade position to the heat transfer performance of double skin curtain wall. The simulation results show that the position of the sunshade has great influence to the temperature of the exterior surface of the inner hollow glass curtain wall. With different sunshade positions, the temperature of the exterior surface of the inner hollow glass curtain wall may vary from 2.7 to 3.5℃. When the sunshade is located at the position between 50 and 125 mm away from the interior surface of the outer glass wall, the temperature of the exterior surface of the inner hollow glass curtain wall is relatively low. In addition, the position of the sunshade also has a great influence to the temperature distribution of the cavity interior.
