地铁车站通风空调控制系统改造相关技术研究

Research on related technology of subway station ventilation and air conditioning control system rehabilitation and upgrades

地铁车站环控的主要目标是使车站环境保持在设计文件规定的温度范围内,保证车站大系统的舒适性以及各空调小系统房间的正常温度。通风空调系统作为车站各机电系统中的能耗大户,常规的定频定流量系统不利于各个设备发挥出最佳能效,易造成资源浪费,同时缺乏对环境舒适度的调节手段。文章针对传统车站通风空调控制系统改造的方案进行研究,保证火灾联动安全可靠,优化系统配置,并给出调节策略改进方向,为改善车站环境,提高能源利用率做出进一步探索。

The main goal of environmental control of subway station is to achieve the temperature target specifi ed in the design documents,ensure the passenger comfort provided by the large-scale station system and the normal temperature in each air-conditioning small system room.Ventilation and air-conditioning system are the major energy consumption of each electromechanical system in the station,and the regular constant frequency and constant flow system is not conducive to the best energy effi ciency of each equipment,which is easy to cause waste of energy.At the same time,there is a lack of control and adjustment means for environmental comfort.This paper studies the upgrades and rehabilitation scheme of traditional station ventilation and air conditioning control system,ensures the safety and reliability of fire disaster detection network linkage,optimizes the system confi guration,and gives the improvement direction of control and regulating strategy,so as to further explore the improvement of station environment and energy utilization.
