Thermo-economic analysis and multi-objective optimization.
Exergy and Thermoeconomic Analyses for Thermal Systems. A general exergy balance equation (48) and the corresponding cost-balance equation (49) that are applicable to any component of thermal systems have been formulated. The exergy of material stream involved in the component of any thermal system was decomposed into thermal, mechanical and chemical exergy flows and an entropy-production flow.
The approach employed is based on the Thermoeconomic Functional Analysis (T.F.A.), which, through definition of the “functional productive diagram” and the establishment of the capital cost function of each component, allows the marginal costs and the unit product costs, i.e., the “internal economy,” of the functional exergy flows to be obtained in correspondence to the optimum point.

An analysis of the use of thermoeconomic diagnosis methods is required, as these methods may prove applicable. To accommodate the analysis, a numerical model of a transcritical booster refrigeration plant is considered in this paper.. Novi Sad. The authors were given the opportunity to expand and enhance their papers. The papers were further.
Important studies on thermoeconomic analysis and optimization of combined heat and power production are listed based on the methodology used and the type of system considered. Exergoeconomics is also called thermoeconomics, and thermoeconomic analysis methodologies combine economic and thermodynamic analysis by applying the cost concept to exergy which accounts for the quality of energy.
Exergy and exergoeconomic analyses have been used to set out weaknesses of the postcombustion CO2 capture unit of Besat power plant that uses an ammonia absorption refrigeration system for CO2 liquef.
The analysis shows that reducing the plant inlet temperature by 2oC could lead to power gain of 2.02MW and increase of plant efficiency from 21.76% to 21.90%. The economic analysis also indicates that the total saving resulting from the application of the evaporative cooling depends on the power gained which is.
