Abstract: 针对集中空调冷水侧基本自动控制系统,设计了两个上位机控制器,分别仅对供回水压差和同时对压差与冷水供水温度进行实时优化;通过仿真实验分析了控制器对系统控制稳定性和系统能耗的影响。结果表明,综合考虑制冷机和二次泵系统的上位机控制器具有较好的可实施性,能在保证系统运行稳定的前提下减少冷水侧能耗。 
From the viewpoint of basic automatic control system, designs two chilled water supervisory controllers and applies them to digital simulators to real time control of the supply/return pressure difference and of both the difference and the supply chilled water temperature. Analyses the influences of the supervisory controller on control stability and energy consumption of the system by simulation experiment. The simulation results show that the controller making trade off between chillers and chilled water pumps is practicable in saving the total energy of chilled water system while still keeping the control stability.
