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...

Finite time exergoeconomic performance of a combined cooling, heating and power generation (CCHP) plant composed of one endoreversible closed Brayton cycle and one endoreversible four-heat-reservoir absorption refrigeration cycle is investigated by using finite time thermodynamics. Heat conductance distribution among hot-, cold-, thermal consumer-, generator-, absorber-, condenserand evaporator...

Due to the lack of natural water resources and high consumption in industries, desalination systems are good options supply demands, especially regions with a crisis. If these wastes used thermal cycles, addition improving efficiency reducing energy consumption, production environmental pollutants can also be reduced. In this paper, multi-stage flash brine recirculation (MSF-BR) system Abadan r...

This paper aims to provide comprehensive 4E (energy, exergy, exergoeconomic, and exergoenvironmental) advanced exergy analyses of the Refrigeration Cycle (RC) Heat Recovery (HRRC) comparison performance with R744 (CO2) R744A (N2O) working fluids. Moreover, multi-objective optimization systems has been considered define optimal conditions best cycle from various perspectives. In HRRC, heat recov...

Penerapan konsep pemanfaatan limbah penggilingan padi sebagai sumber energi dapat mendukung peningkatan produktifitas terbarukan. Konsep eksergoekonomi dijadikan salah satu langkah untuk melihat peluang sekam penambah di sistem yang telah teritegerasi dengan gasifier. Specific Exergy Cost (SPECO) metodenya, dimana metode tersebut menggabungkan analisis eksergi dan ekonomi menerapkan biaya ke da...

The decision-making process behind the selection of a gas turbine engine (GT) is crucial and must be made in accordance with economic, environmental, technical requirements. This paper presents relevant exergoeconomic exergoenvironmental analyses for four GT engines different compressor configurations. configurations are identified according to type compressor: axial, axial-centrifugal, two-sta...

Due to the necessity of using highly efficient power generation systems to reduce fuel consumption and air pollution, the integration of different energy systems is promising modification to achieve higher efficiency. In this paper, the integration of an Internal Reforming Solid Oxide Fuel Cell (IRSOFC)-Gas Turbine (GT)-Organic Rankine Cycle (ORC) system has been proposed. In this regard, therm...
