| 摘 要： | 把含湿多孔介质置于建筑墙体结构中,在室外环境的作用下,多孔介质外表面和内部的水分蒸发吸热,为房间提供部分冷量。文章表述将含湿多孔介质置于建筑北墙中,在建立多孔介质热湿平衡的基础上,采用描述非饱和多孔介质热质迁移的数学模型,分析了室外环境参数及多孔床层结构对床层内温度分布、蒸发量场及水蒸气迁移的影响,为多孔介质应用于建筑结构的推广和应用提供理论指导。

| Abstract: | In this paper, the wet porous media has been used in building wall and the cooling is supplied due to the evaporation of the porous media. Base on the thermal balance, the mathematical model on heat and mass transfer in the unsaturated porous media and the effective refrigeration and non-effective refrigeration of the porous evaporative cooling plate are developed for analyzing the effect of the environment condition and the porous layer structure on the temperature field, evaporation rate field and water v... |
