室内不同通风方式对流场的影响

Influence of Different Indoor Ventilation Modes on Flow Field

文章通过Fluent软件分析大型会议室内不同送风方式下的流场分布情况,对常见送回风方式下的速度场和温度场进行研究,模拟计算获取三种送风方式下的流场云图,对比分析各种送风方式对室内流场的影响。分析结果表明,在侧送侧回、上送下回和下送上回三种通风方式中,下送上回式送风在大型会议室工作区域的通风效果是最好的。模拟结果为有效选取简单可靠的通风方式提供了依据,为室内空调通风设计提供了简明的方案。

In this paper,Fluent software is used to analyze the flow field distribution in large conference rooms under different air supply modes,study the velocity field and temperature field under common air supply and return modes,simulate and calculate the flow field nephogram under three air supply modes,and compare and analyze the influence of various air supply modes on the indoor flow field.The analysis results show that among the three ventilation modes of side supply and side return,upper supply and lower return,and lower supply and upper return,the ventilation effect of lower supply and upper return air supply in the working area of large conference room is the best.The simulation results provide a basis for effectively selecting simple and reliable ventilation methods,and provide a concise scheme for indoor air conditioning ventilation design.
