高大空间膜结构屋顶展厅置换通风空调设计

摘要

Presents the design of a Shanghai Expo pavilion project, calculates the supply flow rate with the displacement ventilation CFD predictive equation deduced by Professor Chen Qingyan. Simulates and optimizes the temperature and air velocity distribution, and tests the temperature during the operating. Draws a conclusion that the project can be one case to predict supply flow rate in large space by using Chen's CFD predictive equation.%介绍了上海世博会某膜结构屋顶展厅的置换通风空调设计,采用陈清焰置换通风CFD模拟公式计算了送风量.对室内温度场、速度场进行了模拟及优化,并在运行期间进行了温度实测.结论是本项目可作为陈氏置换通风CFD模拟公式应用于大空间尺度的一个案例.
