The purpose of this research is to investigate thermoeconomic optimization and exergy analysis of transcritical CO2 refrigeration cycle with an ejector. After modeling thermodynamic equations of elements and considering optimization parameters of emerging temperature of gas of cooler (Tgc) , emerging pressure of cooler's gas (Pgc) , and eva...

Although the gas turbine combined cycle (GTCC) system has better environmental performance, it still emits pollution gases such as CO2 and NOx. It is reasonable necessary to add cost power production of GTCC system. Based on structure theory thermoeconomics, through pricing pollutants (considering costs NOx emission), thermoeconomic (ETC) model developed in this study, which achieves absolute i...
