集成度对热经济学成本的影响研究

Effect of the Integrated Level on Thermoeconomics Cost

热经济学分析的通用方法是将能量系统划分成若干个子系统,然后按各个子系统列出现金平衡方程和补充方程,进而得出各股流的成本。分析了系统集成度对热经济学成本的影响,并分析了集成度引起成本变化的原因,进而对集成度的合理选取提出了建议,并通过实例计算验证了结果的正确性,为热经济学方法的应用提供了参考。

Energy system is divided into several subsystems in the thermoeconomics analysis,in which adds cash balance equation and the supplementary equation to every subsystem, to work out exergy cost of each exergy flow. A specific example is given to analysis the effect of system integrated level on thermoeconomics cost and the reason of varying cost. Based on the computation results, some suggestion is given to choosing integrated level more properly and show the convenience in the c analysis
