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送、回风口同侧布置、异侧布置的室内空气流动的速度场和温度场。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:回风口与送风口同侧布置、异侧布置对置换通风的气流组织影响不大,置换通风在大空间建筑空调中有应用价值。
Velocity field and temperature field of replacement ventilation of air-conditioning in a typical large space building are studied using FIDAP software. The influences of different location of the air return grille is analyzed. The airflow model is based on the incompressible Reynolds-averaged Navier-Stokes equations. The turbulence model adopts the K-ε two equations model. The results indicate the influence is little and the replacement ventilation can be used for air-conditioning in large space buildings.
