| Abstract: | A finite-time thermoeconomic performance analysis was carried out for a two-stage endorever-(sible) combined refrigeration cycle model.The thermoeconomic objective function for this system was derived.The optimal performance parameters and design parameters for minimized objective function were obtained.The relation between the temperatures of working fluid,working years and the thermoeconomic objective function was investigated. |
