基于平衡优化器算法的多联机系统优化控制研究
Research on Optimal Control of Variable Refrigerant Flow System Based on Equilibrium Optimizer Algorithm
摘要
Abstract
In this paper,variable refrigerant flow(VRF)system optimization control method based on the equilibrium optimizer(EO)algorithm is used to study the control strategy for energy saving and carbon reduction of the VRF,and the accuracy of multiple linear regression,multi-layer perceptron and the hybrid model of the both on the external unit power and cooling capacity of the VRF system are analyzed respectively.The external unit power of the optimal control based on the EO algorithm is compared with the original control strategy of the VRF system under steady-state conditions.The results show that,when modeling the power of the external unit,the combined working conditions of the external unit switch can effectively improve the accuracy of the modeling;the accuracy of the multiple linear regression and multi-layer perceptron hybrid model is the highest,and the values of goodness of fit are above 0.95.Optimizing calculations based on EO for steady-state working conditions have a good energy-saving effect,with a maximum energy-saving rate of 25.4%,a minimum energy-saving rate of 5.8%and an overall energy-saving rate of 17.5%.关键词
