摘要
对热经济学分析方法进行了系统介绍,引入了成本差和经济系数作为系统热经济性的评价标准,并以冷凝水回收系统为例,对其进行了热经济性分析,得出了其各个子系统的成本差和经济系数,指明了系统中的用能薄弱环节及其主要原因,同时得出了在年运行时间不同的情况下,系统产品的总成本差随年运行时间变化的规律。
A thermo-economic analysis method is systematically being presented with Exergy-Cost-Difference (ECD) and exergo-economic factor as the criterion for evaluating the system's thermo-economic efficiency. A Sealed Condensate Water Recovery System (SCWR) is taken as an analysis example and the ECD and the exergo-economic factors of all its sub-systems calculated. Components, inefficient in energy utilization and relevant main causes, are pointed out as well. The functional relationship between the system's total operating cost and its annual operation time is obtained simultaneously.Figs 4, tables 2 and refs 7.
