Abstract：
Analyses the effect of different pressure difference control methods on hydraulic stability of variable flow air conditioning water systems, including main pipe pressure difference control and end pressure difference control of direct return system, reversed return system and loop pipe network. The results indicate that end pressure difference control of reversed return system and loop pipe network makes the most desirable hydraulic stability.
Keywords:variable flow system, end pressure difference control, main pipe pressure difference control, hydraulic stability
