Development, analysis and performance assessment of a combined solar and geothermal energy-based integrated system for multigeneration

摘要: Abstract In this paper, a novel solar and geothermal energy-based integrated multigeneration system is proposed for multigenerational product plan. The includes two ORC (organic Rankine cycle) power turbines, thermal energy storage systems, an absorption chiller, heat pump space heating drying system. present analyzed thermodynamically through exergy methodologies, the performances of systems subsystems are assessed incorporating analyses specifically four cases; single generation, cogeneration, tri-generation multigeneration. Both destruction losses in sub-embodiments hence overall determined. Several design parameters, including mass flow rate temperature fluid, turbine inlet pressure, ambient conditions, varied to evaluate their effects on performances. efficiencies system, while working mode, found be 51% 62%, respectively, whereas these generation mode order 22% 54%, respectively. This superior conventional single-source-based systems.
