会议室空调气流组织形式的数值模拟研究

Numerical Simulation of Different Air Distribution of Air-conditioned Conference Rooms

办公区里的会议室为重要工作场所,其环境质量的优劣直接影响工作的效率。以计算流体力学和传热学为基础,利用CFD软件对室内混合通风与置换通风两种气流组织进行数值模拟。结果表明:在温度场、速度场、温度效率及人体热舒适性等方面,置换通风均优于混合通风方式。

Office conference rooms are important work places,the environment quality of which will directly affect the efficiency.Based on the computational fluid dynamics and numerical heat transfer theory,numerical simulation was taken for two different ventilation methods with the software CFD.The results showed that： displacement ventilation method temperature field,velocity field,temperature efficiency and human thermal comfort are better than mixing ventilation method.
