Parallel-connection refrigerator load optimal distribution method, storage medium and equipment

Abstract

The invention discloses a parallel refrigerator load optimal distribution method, a storage medium and equipment. The method comprises the following steps of creating an optimization model according to refrigerators and a power performance curve; utilizing an improved firework algorithm to initialize a partial load rate sequence of the parallel refrigerator, and taking the sequence as an initial group firework; calculating the fitness of each firework, and the number of explosion sparks and the spark radius generated by explosion of each firework according to the fitness to generate the explosion sparks; calculating variation sparks which can be generated by each firework according to the Levy variation operator; taking the initial fireworks, the explosion sparks and the variation sparks as new populations to perform roulette iterative selection, wherein an evolution direction evolves towards the direction of the minimum energy consumption, stopping iteration until the condition of theminimum energy consumption or the maximum number of iterations is met, and taking a partial load rate sequence of the iteration as a partial load rate of each refrigerator; the optimization operationproblem of the parallel-connection refrigerator is solved, and energy saving is achieved on the premise that the requirement is met.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and in particular relates to a method for optimizing load distribution of parallel refrigerators based on an improved firework algorithm, a storage medium and equipment. Background technique [0002] With the continuous improvement of the building level, buildings with specific functions gradually appeared. In order to meet the comfort of the people in the building, the central air-conditioning system has been continuously improved until now it has reached a very mature level. The energy consumption of the central air-conditioning system has always accounted for a large proportion of the building energy consumption, so it is of great significance to conduct energy-saving optimization research on the central air-conditioning system. At present, in the design process of the central air-conditioning system, advanced control strategies still cannot be applied to actual con...

AI Technical Summary

Problems solved by technology

At present, in the design process of the central air-conditioning system, advanced control strategies still cannot be applied to actual control, and more rely on traditional human control to solve problems, which will cause empirical problems. Only experience Rich management personnel can better meet the requirements of control

The energy consumption of the chiller in the central air conditioning system is relatively large, but the parallel chiller system is generally operated under a partial load rate, and the entire system cannot reach an efficient operating state
