In this paper, the authors applied the thermoeconomic optimization technique to a LiBr absorption refrigeration system, where various components of the system such as condenser, evaporator, generator, and absorber heat exchangers were optimized.Abstract:
Optimization of thermal systems is generally based on thermodynamic analysis. Thermoeconomic optimization technique combines thermodynamic analysis with economic constraints to obtain an optimum configuration of a thermal system. In this study, the thermoeconomic optimization technique is applied to a LiBr absorption refrigeration system. Various components of the system such as condenser, evaporator, generator, and absorber heat exchangers are optimized. Additionally, optimum heat exchanger areas with corresponding optimum operating temperatures are determined. A cost function is specified for the optimum conditions. Finally, an example for the optimum design of a 20 kW LiBr system is given.read more

The Exergy Method of Thermal Plant Analysis
TL;DR: The Exergy Method as mentioned in this paper is a method of thermodynamic analysis in which the basis of evaluation of the thermodynamic losses follows from the Second Law rather than the First Law of Thermodynamics and has gained in the last few years many new followers, both among practising engineers and academics.
