摘　　要：本文对循环水泵不同变频控制方式进行了分析,建立了计量供热系统二次网的运行调节模型,采用理论计算方法,以实际工程为例计算出二次网采用不同控制与运行调节方式组合下的循环水泵能耗,并进行了比较分析,得出采用远端定压差控制与分阶段定供水温度调节结合下的水泵能耗最低。This paper analyzes different control modes of the variable frequency pump and establishes different operation and regulation methods of the secondary network in heat metering system. According to the heat metering actual project in Beijing, it calculates the energy consumption of circulating water pumps of the secondary pipe network in different combinations of control ＇ and regulation, and carries on the comparative analysis. It is concluded that circulating water pumps will be the lowest energy consumption under the combination of the remote constant pressure control and constant water temperature regulation by stages.
