Study on the Heat and Moisture Properties of the Indoor Environment for Communication Equipment Room in Deep-Lying Building Envelope

为使建立的机房热湿耦合传递数学模型能够描述多孔介质流的热湿迁移,建立了CFD和毛细多孔介质的直接耦合模型,此模型把描述毛细多孔介质热湿迁移的控制方程整合到CFD求解器中。对深埋地下通信机房的墙体、室内空气环境进行了试验及基于此模型CFD模拟研究,得到了吊顶、墙面、地面温度和相对湿度及散湿的变化规律,为深埋地下通信机房的设计提供了一定的依据。

In order to describe heat and moisture migration in porous media flow by establishing coupled heat and moisture transfer mathematical model for communication equipment room,The directly coupled models between CFD and capillary porous media model was introduced.This model integrates the control equations describing the heat and moisture migration of capillary porous media into CFD solver.Researching on coupled heat and moisture transfer in deep-lying communication equipment room wall,the indoor air environment and the ceiling,temperature,relative humidity and wet bulk variation are obtained,which provides certain basis for designing deep-lying communication equipment room.
