地铁环控系统集中供冷监控策略研究

Monitoring Tactics of Central Cooling in Metro Enviroment Control System

根据广州地铁4号线集中冷站监控系统中应用的监控策略,探讨了集中供冷方式中从供冷侧到用户侧的控制策略,涉及冷水机组的群控策略、变频二次泵频率控制、变频二次泵的台数控制、末端二通阀的开度控制等,以实现供冷系统的节能降耗以及优化控制。

With an introduction of the monitoring system of the central cooling station in Guangzhou Metro Line 4,this paper discusses the control method of the central cooling station from aspects like the cold water supply,the control of refrigerating machines,the opening control of transducers and valves,to achieve the optimized control and energy saving goal.
