摘要
分析了一次泵变流量系统中用户侧和冷热源侧流量和温差变化不同步的原因,指出了变化不同步带来的问题,根据不同的水泵控制形式,给出了不同的旁通控制方法,并给出了各种旁通控制法的旁通流量计算公式。
Analyses the causes for out-of-step changes in flow rate and temperature difference of user side and cold/heat source side. Points out the problems caused by the out-of-step changes. Presents different bypass control methods and corresponding calculating formulas for bypass flow rate according to different pump control methods.
