摘要
应用CFD技术对华东地区某双层幕墙冬季时的传热特性进行了分析,采用层流模型对热通道的温度场和速度场进行了模拟,最终得出双层幕墙的综合传热系数K和冬季保温增热效果,计算结果表明该双层幕墙系统在冬季运行时具有良好的节能效果。
CFD techniques were used to analyzed the thermal performance for a winter double skin facade in East China. Laminar model was chosen to simulate the temperature field and flow field of the thermal cavity. Integrated thermal coefficient K and the value of heat preservation and increase were finally calculated. The numerical results showed that the facade system could reach excellent energy-saving performance in winter.
