以某大型展厅为背景,分析了大空间气流组织的影响参数,通过对比分析推荐了适用于大空间气流组织的数学物理模型,并利用CFD计算流体力学软件对展厅进行了室内气流组织的初步设计及参数优化,得到了采用不同气流组织状态下人员活动区的温度分布情况,从而为暖通空调节能设计提供依据。 Taking a large exhibition hall as the background, the influence parameters of large space airflow organization are analyzed, and the mathematical physics model suitable for large space airflow organization is recommended through comparative analysis. The CFD CFD software is used to design the indoor airflow organization in the exhibition hall And the parameters are optimized, the temperature distribution of the active area of ​​the personnel under different airflow states is obtained, which provides the basis for energy-saving design of HVAC.
