定流量一级泵/变流量二级泵系统设置条件解析

Constant flow prim ary pump/variable flow secondary pumpsystemsettingconditions

采用定流量一级泵/变流量二级泵系统的目的是降低整个空调水系统的能耗,与适应负荷特性或改变水温的目的是不同的。分析了定流量一级泵/变流量二级泵系统的设置条件,认为"各环路负荷特性相差悬殊"和"各环路的水温或温差要求不同"不宜作为设置变流量二级泵的推荐条件。设置条件应该是:系统作用半径较大、设计水流阻力较高或各并联环路之间的阻力相差悬殊。

The constantflowofprimary pump/variable flow secondary pump system purpose is to reduce energy consumption of the air conditioning water system, and to adapt to the load characteristic or change the purpose of water temperature is different. Analysis of the constant flow of primary pump/variable flow secondary pump system setting conditions, think ＂each loop load characteristic difference＂and ＂loop water temperature＂or temperature.
