Abstract EN
The chilled water system of central air conditioning is a typical hybrid system.
The dynamic adjustment of cooling capacity based on hybrid system can achieve accurate temperature control and real-time energy saving.
Mixed logical dynamical (MLD) systems have advantage for solving constrained optimization problems of this type of case by numerical methods.
This paper proposes a novel modified type of MLD system, which enhances the model applicability and improves the switching flexibility and control effect for the framework.
In order to meet the needs of cooling capacity and energy saving, the optimal control problem is transformed as MIQP problem by defined performance index.
As a numeral example of application, the model and control method is used in pumps group control for variable water volume in chilled water system of central air conditioning.
At last, the dynamic and energy-saving effects of the system are simulated, which shows the ideal control results.
