  二次泵系统
     Control and Adjusting Regime Point of Secondary Pumping System
     二次泵系统的控制方式及调节工况点
短句来源
     Points out that, even if constant speed pumps are used ,the primary/secondary pumping system is energy saving, the increase in first cost is not large,the simple payback year is short, and that it's control is simple. So,in ice storage system, the primary/secondary pumping system, as compared with the primary system, is a better way.
