Özet

A Brayton plant-based multigenerational system is proposed and investigated thermodynamically through energetic and exergetic approaches in this study. Liquid hydrogen, electrical energy, heating-cooling and fresh water are the useful outputs produced by the combined plant. For this purpose, the Brayton cycle, organic Rankine cycle, multi-effect distillation plant, single-effect absorption cooling plant, hydrogen generation and liquefaction unit are used in the multigeneration system design. The study targets are to design a novel multigeneration system design, develop the related software codes, analyze the system thermodynamically, and evaluate the effects of plant design indicators. Thermodynamic assessment results indicate that the energy efficiency of the multigeneration system ranges between 63.64% and 74.31%, the exergy efficiency value ranges from 55.67% to 67.35%. Parametric analyses performed in this study indicate that the most influential parameter is the fuel mass flow rate. Also, it should be stated that an increase in the dead state temperature, combustion chamber temperature, and fuel mass flow rate positively affects the plant effectiveness.
