某城市轨道交通运营指挥大楼调度大厅空调系统设计浅析

HVAC system design for dispatching hall in a city rail transit operation command building

对某城市轨道交通运营指挥大楼的空调系统设计进行了介绍。针对调度大厅,利用CFD模拟对比分析了2种送风方式人员活动区热舒适性,通过分析得出了工位送新风和顶部旋流风口送风相结合的方式能较好满足大厅室内热舒适要求。此外,根据现场实测对CFD模拟结果进行了验证。

This paper presents the air conditioning system design of a city rail transit operation command building.Aiming at the dispatching hall,CFD simulation is used to compare and analyse the thermal comfort of the personnel activity area in two air supply modes.Through the analysis,it is concluded that the mode combining the outdoor air supply at the station and the swirling air supply at the top can better meet the requirements of indoor thermal comfort in the hall.In addition,the CFD simulation results are verified by field measurement.
