Fuzzy Control for Variable Cooling Water Flow System

Abstract:

The variable flow cooling water system can achieve energy saving benefits just like variable primary flow chilled water system for central air conditioning system. How to design the control system with appropriate control algorithms and control strategies is particularly important. We can clarify the basic control principle of variable cooling water flow technology based on the analysis on DOF (degree of freedom) of cooling water systems, it is important for control system design. The article pointed out explicitly that the realization of variable flow technology for cooling water system must construct two control loops, one for cooling water supply temperature the other for return temperature, further more discussed control strategies for two control loops. In the end the article illustrated the synchronous frequency conversion technology for multiple cooling water pumps system to avoid overload when part of pumps put in operation
