Research on Optimization Control of Central Air Conditioning System Based on Multi-Objective Programming

摘要: 为了提高中央空调系统的工作效率，同时降低能源消耗，需要对中央空调系统进行节能优化控制研究。现有的中央空调系统控制策略很难实现实时控制，且优化控制效果较差。为此，提出了基于多目标规划的中央空调系统动态优化方法。该方法先研究了中央空调系统各变量的变化规律，并对数据进行降维；然后，使用多元回归分析方法得到变量的回归方程；在此基础上，以设备运行状态和转速为决策变量，以系统总耗电量和系统效率为目标函数，在设备转速、状态、系统稳定性和设备运转等约束条件下，建立了基于多目标规划的中央空调系统动态优化模型。优化结果显示，所提方法优化控制效果较好，有效地降低了系统总耗电量。

Abstract: In order to improve the efficiency of central air conditioning system and reduce energy consump-tion, it is necessary to study the energy-saving optimization control of the central air conditioning system. However, the current control strategy of central air conditioning system is difficult to realize real-time control, and has the problem of poor optimization control. Therefore, we propose an optimization control method for central air conditioning system based on multi-objective programming. Firstly, we study the changing rules of the variables in the central air conditioning system, and reduce the dimension of the data. Then, we used the multiple regression analysis to obtain the regression equation of the variable. On the basis of the above, we use the operating condition and speed of the equipment as the decision variables, and take the total energy con-sumption and the system efficiency as the objective function. Under the constraints of equipment speed, state, system stability and equipment operation, we establish the optimization control model of the central air conditioning system based on the multi-objective programming model. Finally, the optimization result shows that the optimized control effect of our proposed method is better, and it can effectively reduce the total power consumption.
