某国际机场航站楼空调气流组织的数值模拟与分析

Simulation and Analysis on Airflow in an Air-conditioned International Airport Terminal

以某国际机场二期扩建工程航站楼内部空调气流组织方案优化设计为目标,利用CFD仿真软件在夏季典型气象参数下,对采用不同空调气流组织设计方案时室内的温度场、速度场分布情况进行了模拟,分析了不同送风参数以及送、回风口数量等对气流组织效果的影响规律,提出了航站楼采用置换通风与辐射供冷/供暖复合空调方案时合理的送风参数和地板辐射供冷参数建议值,给出了优化的置换送风口和幕墙附近与二层通廊埋地盘管的数量和布设间距等。

The temperature and velocity field are simulated with simulation software CFD in different design schemes of airflow distribution,in order to optimize the design of the airflow distribution inside an international terminal at the second phase of construction.The influ ence of air supply data,the number of air distributor and return air inlet on the airflow distribution is analyzed.The recommended data for air supply and floor cooling system are proposed when the displacement ventilation and radiant cooling/heating are combined.Besides,the number and interval of optimized displacement air supply inlet and underground coil,located near the curtain and corridor on the second floor,respectively,are recommended.
