Chilled water circulation system control optimization method, system and equipment

Abstract

The invention discloses a chilled water circulation system control optimization method, system and equipment. The method comprises the following steps of recognizing an antigen; taking chilled water supply temperature as an antibody, and generating two initial antibody populations in random and fixed step length modes respectively; optimizing the two initial antibody populations by adopting a parallel artificial immune algorithm to obtain two next-generation antibody populations; conducting inter-population individual exchange on the two next-generation antibody populations by adopting an immigrant operator to obtain two new antibody populations; optimizing the two new antibody populations by adopting the parallel artificial immune algorithm; judging whether a termination condition is met or not, and outputting an optimal solution, namely the optimal chilled water supply temperature; and according to the optimal chilled water supply temperature, obtaining the number of started chilled water pumps and the speed ratio under the condition that the power consumption of a chilled water circulation system is minimum through calculation. According to the method, the system and the equipment, water chilling units and the chilled water pumps are comprehensively optimized, cooperative matching operation analysis of different devices is achieved, and the method, the system and the equipment have the advantages of being high in rate of convergence and stability.

Description

technical field [0001] The invention belongs to the technical field of air conditioning system control, and in particular relates to a control optimization method, system and equipment of a chilled water circulation system. Background technique [0002] In recent years, central air-conditioning systems have been widely used in modern large buildings to provide a comfortable indoor thermal environment; as the most important energy-consuming equipment, chilled water systems account for about 60% of the total energy consumption of central air-conditioning systems. Although many chilled water systems are designed and selected as energy-saving and efficient systems, the system equipment is designed according to the maximum air-conditioning load. When the system is under partial load, each equipment cannot be dynamically adjusted according to the hourly changes of environmental parameters and load demand. , causing the equipment to deviate from the optimal operating level, there i...
