Control Algorithms and Control Strategies for Variable Primary Flow Chilled Water Systems
In recent years,variable primary flow control technology for chilled water systems has played an important role in energy saving.How to design the control system with appropriate control algorithms control strategies is particularly important? This article described the prerequisite for the realization of variable flow technology and discusses the three aspects emphatically.We can clarify the basic control principle of variable primary flow technology based on analysis on DOF (degree of freedom) of chilled water systems,it is important for control system design.The article illustrated the synchronous frequency conversion technology for multiple chilled water pumps system to avoid overload when part of pumps put in operation,finally discussed control algorithms control strategies for variable primary flow system.The article proposed that the fuzzy control algorithm is the good choice,then explained the control strategies for judging to addsubtract chiller or pump based on the maximum and minimum operating frequency of chilled water pumps with a actual project.
