Abstract：
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.
