摘要
以贵阳地区为例,采用Fluent软件对贵州省居住建筑外掠墙体通风冷却措施进行数值模拟,通过计算得出不同送风温度和送风速度下满足有效通风所需要的时间,从而分析外掠墙体通风措施的有效性及其节能效果。结果表明:相同冷却效果下,与使用空调所产生的能耗相比,贵阳地区采取该措施的节能率高达67.9%。
The Fluent software is applied to simulate the wall ventilation of residential buildings in Guizhou Province. According to the simulation results, the time of effective ventilation is obtained, and the energy efficiency of ventilation measures is analyzed. The results show that, compared with the energy con-sumption by air conditioning system, the energy saving rate of wall ventilation is up to 67.9% under the same cooling demands.
