A new thermoeconomic methodology for energy systems
Kim, D.J. - In: Energy 35 (2010) 1, pp. 410-422
Thermoeconomics, or exergoeconomics, can be classified into the three fields: cost allocation, cost optimization, and cost analysis. In this study, a new thermoeconomic methodology for energy systems is proposed in the three fields. The proposed methodology is very simple and clear. That is, the...
