摘要
本文介绍了热通道玻璃幕墙的简单数学模型。模型的物理概念和Trombe墙相似。该幕墙由外侧单层和内层中空玻璃组成热通道。列出稳态状态下热通道的热平衡方程,通过线性矩阵求解了两个玻璃和通道内空气的平均温度,并使用热阻网络表达在太阳辐射条件下,热通道的传热过程。计算机模拟表明,夏热地区热通道幕墙内层中空玻璃的外表面温度较传统幕墙的表面温度有明显降低,由太阳透射引起的房间得热也有较大减少。
A simple mathematical model of glazing curtain wall with thermal channel （double skin facades） is proposed. The physical model is similar to Trombe wall. A thermal channel is formed with a hollow glass of glazing curtain wall. Steady state heat transfer equations were set up to determine the boundary temperature between two glasses cover and air average temperature in channel. Using a thermal rcsistance network the channel transferring process is expressed. Results from computer modeling indicated that in summer the exterior temperatures of hollow glass curtain wall and gaining load are lower than traditional ones by way of solar radiation.
