Research on Optimized Energy Saving Control System of VAV Air Conditioning System

VAV air conditioning system has complex structure, huge scale, many variables, strong coupling and various uncertainties. The traditional automatic control methods adopt the method that the controlled parameters of the system are fixed, which can satisfy the stable operation of the system, but it will bring a great waste of energy. In this paper, the optimization objectives and constraints to minimize energy consumption are proposed, and the optimization model of central air conditioning system is established. The optimization objective of VAV is minimum energy consumption.It can meet the comfort and stability, reduce the energy consumption of the system and achieve the best energy-saving effect.
