摘要:
分析了复合墙体内空气与水两种流体域的流动传热状况,借助于Fluent软件,分别研究了自然通风
与机械通风状态下该模块墙体的热工性能.结果表明:与常规的建筑墙体相比,利用水的蒸发冷却对外墙内表
面进行降温的复合通风外墙结构具有很好的隔热效果.蒸发冷却式通风外墙只能采用水层位于通风空气层
内侧的结构形式.通过提高空气入口速度,可以达到更好的隔热效果.而通风机的安装位置和送风方向的选择
相对自由.水层厚度与空气层厚度对墙体稳态热工性能的影响很小
Abstract:
A new modular evaporative cooling ventilated wall was presented.The thermal performance of the wall was
studied under natural ventilation and mechanical ventilation condition.The results show that:the evaporative cooling ventilated
 wall with reasonable structure shows obvious advantage in heat-insulating performance.Only the wall structure of
air layer outside water layer is reasonable.And with the increase of air inlet velocity,it shows better heat-insulating performance.
The direction of inlet airflow shows only weak effect on thermal performance,so the location of the fan or the
tuyere is relatively free.The water layer thickness and the air layer thickness show little effect on steady thermal performance.
