　　(二)、解决措施

　　1、循环系统
        采用 REGIN节能控制系统，根据冷却水系统和冷冻水系统的供回水温度进行采样和控制，通过变频器对循环泵系统进行控制，调整各泵电机的工作状态(主要是转速)，保证各电机以最小功率输出，精确地进行温度控制，延长循环水系统的寿命，并大幅度地节约电能。另外，即使变频控制回路发生故障，REGIN节能控制系统的变频—工频切换功能也可将机组切换到工频工作，以确保设备正常工作的需要。

　　(三)、节电原理分析

　　1)、节电原理 由流体传输设备水泵的工作原理可知：
水泵的流量与其转速成正比;水泵的压力(扬程)与其转速的平方成正比，而水泵的轴功率等于流量与压力的乘积，故水泵的轴功率与其转速的三次方
