摘　　要：区域能源站基于多能互补,将多种不同形式的冷源经过智能耦合,以满足末端对冷负荷的需求。为使多能互补区域能源站供冷系统能经济、节能、绿色、环保、高效地运行,在设计中冷源装机容量要与运行模式相匹配。基于北京某区域能源站的实际案例,对其项目后期运行模式进行分析,设计其供冷系统各冷源的装机容量。研究表明,在供冷系统中耦合蓄冰槽后,可根据末端负荷变化情况,调整不同的运行模式以降低系统的运行成本,实现经济、高效运行。与传统的单一冷源供冷系统相比,多能互补的供冷系统通过多种能源的智能耦合提高供冷与末端负荷的匹配性,同时降低运行成本。Based on multi-energy complementation,a variety of different forms of cold sources are intelligently coupled in the regional energy station to meet the demand of terminal cooling load.In order to make the multienergy complementary regional energy station cooling system run economically,energy-saving,green,environmental protection and efficiently,the installed capacity of the cold source should match the operation mode in the design.Based on the practical case of a regional energy station in Beijing,the late operation mode of the project is analyzed,and the installed capacity of each cold source of the cooling system is designed.The research shows that after coupling the ice storage tank in the cooling system,different operation modes can be adjusted according to the change of terminal load in order to reduce the operating cost of the system and achieve economic and efficient operation.Compared with the traditional single source cooling system,the multi-energy complementary cooling system can improve the matching of cooling and terminal load through intelligent coupling of various energy sources,and reduce the operating cost.
