摘 要: 从集中空调冷却水侧基本自动控制系统的局部角度出发 ,设计了冷却塔风扇上位机控制器 ,对风扇风量和运行台数进行实时控制 ,并通过仿真试验分析了其对系统控制稳定性和系统能耗的影响 .结果表明该上位机控制器具有较好的控制稳定性 ,并且比常规的风扇转速及台数控制方式更节能 . In this paper,from the viewpoint of basic automatic control system,a cooling tower supervisory controller is designed and tested by applying it on the digital simulator to real time control the tower airflow and tower fan sequencing in central air-conditioning.The simulation results show that the controller is available in improving the control effect,and it can save energy than traditional tower fan sequencing control strategy.
