In this study, 4E (energy, exergy, exergoeconomic, and exergoenvironmental) analysis of an underfloor heating system integrated with the geothermal heat pump a greenhouse usage area 90 m2 has been made. When results applied to its elements were examined, energy efficiency in winter months determined be 77.85% exergy 30.61%. According exergoeconomic analysis, levelized cost as 0.894 dollar/h, un...

Advanced exergoeconomic analysis is applied on process configurations for co-production of LNG and NGL. This analysis provides information on the origin of the irreversibility as well as the irreversibility value of the process. The exergy destruction, exergy destruction cost, and also investment cost, are divided into two available/unavailable and endogenous/exogenous parts. The results of adv...

C3MR, MFC, and DMR processes in an integrated LNG-NGL-NRU structure are investigated using the conventional and advanced exergy and exergoeconomic analyses. The results of advanced exergy analysis reveal that in most of the equipment, the highest amount of irreversibility is occurred because of endogenous exergy destruction. In C3MR process, compressor C5 with 9730 kW; in MFC process, compresso...

In this study exergy and exergoeconomic analyses of a refrigeration system with two evaporators and an internal heat exchanger were performed. The analysis of the whole system included various thermodynamics parameters such as sustainability index, exergetic improvement potential, ratio of the thermodynamic losses(energetic and exergetic losses) to the capital cost, relative irreversibility for...
