摘　　要：本文结合某建筑节能示范客站工程实际,利用Airpak气流模拟软件对候车室内环境进行CFD模拟仿真,研究室内呼吸道病毒污染物产生扩散及分布规律,以便进行有效控制,并对室内风速、空气龄、人员呼出气体迹线和热舒适性进行分析,最后通过现场风速实测验证模型准确性。结果表明,客站空调系统设置技术合理,在确保旅客热舒适的情况下,可降低候车人员交叉感染概率。相关模拟和实测分析方法可为其他大型高铁客站的空调系统设计、安装调试及运维提供有益借鉴。This paper combines the actual situation of a building energy⁃saving demonstration station project,uses the Airpak airflow simulation software to conduct CFD simulations on the indoor environment of the waiting room,and studies the generation,diffusion,and distribution of indoor respiratory virus pollutants for effective control.In addition,the indoor wind speed,air age,exhaled gas trajectory,and thermal comfort are analyzed,and the model accuracy is finally verified through on⁃site wind speed measurements.The results show that the setting of the station′s air conditioning system is reasonable,which can reduce the probability of cross⁃infection among waiting passengers while ensuring their thermal comfort.The relevant simulation and measurement analysis methods can provide useful references for the design,installation,debugging,and operation and maintenance of air conditioning systems in other large⁃scale high⁃speed railway stations.
