基于效率的综合能源系统能效分析模型
Efficiency analysis model of integrated energy system based on the exergy efficiency
摘要
Abstract
Energy analyses that based on the first law of thermodynamicsand and exergy analyses based on the second one are two major methods to evaluate the thermal effiency. The important part of the energy side of energy internet-integrated energy system was taken as the research object,and the integrated energy system model was presented,which aimed on the energy internet project planning of Yizhuang area in Beijing.The model was devided to several parts that contained three different planning projects to calculate and evaluate the energy efficiency and exergy efficiency of the various energy systems. The results indicate that the overall energy efficiencies are seen to vary,for the three system considered,from 71 to 93 percent,and the exergy efficiencies from 34 to 40 percent,and the exergy analyses is an effective method to evaluate the thermal efficiency of the regional integrated energy system that comprises electricity, cold,heat,different forms of energy.关键词
