摘　　要：采用计算流体动力学(CFD)数值模拟方法,探讨不同送风距离及送回口布置形式对候车厅高大空间的温度场、速度场、热舒适指标PMV等因素的影响。从模拟分析来看,确定喷口最大送风距离不仅仅与喷口形式、设置位置、安装角度及出口风速相关,太阳辐射等围护结构影响因素、回风形式、风速场大小也影响喷口最大送风距离;采用另一热舒适评价指标(SET*)简要分析了通过提高送风速度补偿室内温度的方法。文中观点及思路可供此类高大空间空调系统气流组织设计借鉴和参考。The CFD numerical simulation method is used to explore the influence of different air supply distances and the layout of the return ports on the temperature field,velocity field,thermal comfort index PMV of the large waiting hall.From the simulation analysis,in the design and selection of the nozzle,the maximum air supply distance should consider not only the nozzle form,setting position,installation angle and outlet wind speed,but also other factors such as the setting of the nozzle,the return air mode and the wind speed in the working area.At the meantime,thermal comfort e-valuation index(SET*)is briefly analyzed to compensate the indoor temperature by increasing the air supply velocity.The viewpoints and ideas in this paper can be used as a reference for HVAC System design in such large space.
