摘要
测试并模拟西安地区一室内植物墙建筑室内热湿环境,应用Fluent软件对建筑物内墙壁有绿化空间的室内空气温度和气流速度模拟,并与没有植物墙的空间进行分析对比,得出室内植物墙可以降低室内环境温度0.7℃,有效增加室内空气湿度。分析发现植物墙的降温作用与植物的蒸腾作用、栽培基质中水分的蒸发有关。
The indoor thermal and humidity environment of a building with indoor green wall is tested and simulated in Xi’an. The indoor air temperature and wind velocity of the building with planting on the wall is simulated with Fluent software. And the result is compared and analyzed with the space that the building surface without vegetation. The indoor temperature with planting is lower 0.7 ℃ than the space without planting through the testing and simulation. The plant can increase indoor air humidity. The cooling effect of the plant wall is related to the transpiration of plant and the evaporation of the water in the substrate.
