摘要
用FIDAP软件模拟了一典型大空间建筑空调采用置换通风的室内空气流动的速度场和温度扬.分析了回风口高度对室内空气流动的速度场和温度场的影响.空气流动物理模型是以不可压缩、雷诺平均的纳维尔-斯托克斯方程为基础的.紊流模型使用K-ε两方程模型.结果表明置换通风在大空间建筑空调中有好的应用价值,回风口高度对室内气流动的速度场和温度场的影响不大.
Velocity field and bemperature field of replacement ventilation of air-conditioning in a typical large space building are studied by using FIDAP. The influence for velocity field and temperature field with the difference of height of return air is analysed.The airflow model is based on the incompressible, Reynolds-averaged Navier-Stokes equations.The turbulence model is the K-ε two equations model. The results indicate that the replacement ventilation can be used for air-conditioning in a large space building and the influence for velocity field and temperature field with the difference of height of return air is little.
