摘　　要：长期以来旋流风口在大空间的应用受到多种因素限制。本文采用计算流体动力学数值模拟方法,针对不同旋流角度对大空间人员活动区环境影响进行研究。结果表明,当旋流角度为45°时,人贸活动区最为舒适;不同的送风速度对整个人员活动区内速度分布影响较小,但对区域内温度场影响较大。通过智能控制系统监测温度变化,调整送风速度,达到室内的热舒适性要求。本文为旋流风口在大空间中的应用提供理论基础与技术支持。For a long time,the application of swirl diffuser in large space has been limited by many factors.In this paper,a computational fluid dynamics simulation method was used to study the effects of different swirl angles on the environment of large space building.The results show that when the swirl angle is 45°,the occupied region is comfortable.Different air supply velocities have a small effect on the velocity distribution in the occupied zone,but have a significant effect on the temperature field.The intelligent control system monitors the temperature change and adjusts the air supply velocity to meet the indoor thermal comfort requirements.This paper provides theoretical basis and technical support for the application of swirl diffuse in large space.
