摘要
针对水-水源热泵系统普遍存在的运行效率不高的问题,本文提出基于稳态模型的在线优化控制方法,并以分级控制理论为基础,以系统总耗能量作为目标函数,建立了稳态水-水源热泵系统优化模型,重点对水泵能耗模型部分进行改进。最后,采用建立的模型对具体实例进行了优化求解,并对优化结果作了节能效果分析,得出结论:采用本文所提出的优化方法,可提高整个水-水源热泵系统运行效率。
To solve the problem of low-efficient operation of water-to-water heat pump system, an online optimizing control method based on steady state is proposed in this paper. Based on the hierarchical control theory, with total energy consumption of the system as the objective function, the optimizing control model of water-to-water heat pump system is established, and it stresses on improvement of energy consumption model of pumps. The model is adopted to solve an optimizing example and finally the energy saving effect of the optimizing control method is analyzed. The conclusion is obtained that the efficiency of the whole water-to-water heat pump system can be improved when this method is adopted.
