Subway systems are rapidly developing, and their energy consumption is considerably growing. The ventilation and air conditioning system in the subway station is the key energy-consuming system. It consumes a large amount of energy every day to provide a comfortable environment for passengers, and it has therefore received increasingly more attention from researchers worldwide. In this work, the variation law of the ventilation and air conditioning system of a subway station is analyzed from three aspects (energy consumption, load, and temperature) based on field test data, and the problems existing in the operation and management of the system are analyzed. For example, the results show that the total load of fresh air in the station was as high as 34–37%, and about 30 min was required to adjust the indoor temperature to a stable state. In addition, three general models and seven energy-saving strategies are put forward, and their energy saving potentials are estimated. After optimization, the ventilation and air conditioning system is found to reduce energy consumption by more than 30%. Not only are common problems that exist in the actual operation of the subway station ventilation and air conditioning system found in this research, but valuable measured data is also provided for the theoretical research of the thermal environment of the subway and the design of environmental control systems.

地铁系统正在迅速发展，其能源消耗也大大增加。地铁站的通风和空调系统是关键的能耗系统。它每天消耗大量能量以为乘客提供舒适的环境，因此受到了全球研究人员的越来越多的关注。在这项工作中，基于现场测试数据，从能耗，负荷和温度三个方面分析了地铁车站通风和空调系统的变化规律，以及系统运行和管理中存在的问题。被分析。例如，结果表明，该站的新鲜空气总负荷高达34–37％，需要约30分钟才能将室内温度调节到稳定状态。提出了三种通用模型和七种节能策略，并对其节能潜力进行了估算。经过优化后，发现通风和空调系统可将能耗降低30％以上。该研究不仅发现了地铁车站通风空调系统实际运行中存在的常见问题，而且还为地铁热环境的理论研究和环境控制系统的设计提供了有价值的实测数据。 。
