Assessment and optimization of a new sextuple energy system incorporated with concentrated photovoltaic thermal - Geothermal using exergy, economic and environmental concepts

摘要: Abstract This research presents a thermodynamic, economic and environmental impact assessments of new renewable based sextuple system made up an organic Rankine cycle, magnetic refrigeration proton exchange membrane electrolyzer, date dryer unit concentrated photovoltaic thermal collectors delivering power electricity, cooling heating effects, hydrogen, oxygen dried productions. The impacts the substantial design parameters on annual exergy efficiencies, total product cost rates are evaluated. From parametric analysis, PEM electrolyzer current density affects rate less than other within 3.05% turbine inlet pressure yields reduction in by about 3.8%. Moreover, elitist non-dominated sorting genetic algorithm LINMAP decision maker employed to identify final optimum answer desired system. optimization outcomes, performance shows 18.3% for 24.9% improvement criteria. efficiency is improved 27.4% gets 2.12 times. Under conditions, isobutane mass flow reaches maximum value 35 kg/s net output increases 50.25% relation base point.
