摘要：

Thermodynamic model of the solar power organic Rankine cycle (ORC) has been proposed in the present study. Model is developed in MATLAB 2018a for Cyclohexane/R123 mixture-based ORC system driven by series of N-collectors. Four different collector models namely: Case-I, "N series connection of photovoltaic thermal conventional compound parabolic (NPVTCCPC) collector system"; "Case-II: N series connection of photovoltaic thermal (NPVT) collector system"; "Case-III: N series connection of conventional compound parabolic collector (NCCPC) system"; Case-IV N series connection of flat plate collector (NFPC) system" have been integrated with ORC system. Overall thermal performance has been evaluated for each case and compared individually. Case-III (NCCPC) emerged as the best combination in the view of highest collector exit temperature 110 degrees C, heat gain 255 kW, thermal efficiency 14.14%, exergetic efficiency 54.77%. Further, highest percentage of total exergy destruction was observed in evaporator (37-45%) followed by condenser (28-31%), expander (24-30%) and lowest in pump (1-2%). The present developed system could be a promising solution to power crises in remote and off-grid-connected areas.
