technical field
[0001] The invention belongs to the field of energy-saving control of refrigeration systems, and in particular relates to an optimal control method for combined operation of chillers based on model prediction. Background technique
[0002] The chiller is the core component of the central air-conditioning system, and its operating energy consumption accounts for more than 40% of the total energy consumption of the central air-conditioning. For a system in which multiple chillers are jointly operated in a large building, the energy efficiency of the chiller is different under different load rates. A reasonable chiller group control method is adopted to keep the chiller running as efficiently as possible and maximize the operating efficiency of the refrigeration system. It is an important technical way to realize energy saving of centralized air conditioning system.
[0003] The traditional chiller group control adopts the feedback control method, generally by ...
