摘　　要：研发了一种新型冷却塔,通过对冷却塔进塔水流富余能量的分析,设计了一种应用于低水头的微型水轮机,与冷却塔风机相匹配从而实现对冷却塔风机转速的控制,以此满足对出水温度的控制。应用编程软件STEP7-Micro/WIN进行相应的程序编制。应用组态王组建相应的监控界面实现监控界面数据变量与现场设备各个参数的相互连接,总体实现了冷却塔系统的节能运行及自动化控制。A new type of cooling tower has been developed. Through the analysis of flow surplus energy of cooling tower, a kind of micro-turbine which is used for low water head has been designed, matching with the cooling tower fan, in order to control the speed of the cooling tower fan and meet the needs for water temperature control. Then, sol/ware STEP7-Micro/WIN is used for making corresponding programs. King View is used for establishing appro- priate monitoring interface to realize the connection of the data variables of monitoring interface with individual pa- rameters of the field equipment. On the whole, it achieves energy-saving operation and automatic control of the cool- ing tower system.
