摘　　要：一次泵变流量系统是一种更先进、更节能的空调系统设计方案,介绍了一次泵变流量系统的工作原理,针对冷水机组蒸发器侧流量变化反应滞后的问题,提出了对冷水机组实施变流量,并设计了反馈-前馈控制器,提高了冷水机组每分钟允许的流量变化率,使得一次泵变流量系统更加完善。文中还简单介绍了一次泵变流量系统的节能原理-冷水泵变频及旁通阀控制。Once pump variable flow system was a more advanced of more energy saving of air conditioning system design programme, describes has once pump variable flow system of work principle, for cold water unit evaporator side flow changes reaction lag of problem, made has on cold water unit implementation variable flow, and design has feedback-feed forward controller, improve has cold water unit each minutes allows of flow changes rate, makes once pump variable flow system more perfect. Article also give some information on the energy saving of variable primary flow system principlechilled water pumps frequency converter and by-pass valve control.
