摘要	In present paper, thermodynamic analysis and techno-economic assessment of an organic Rankine cycle (ORC) coupled with solar parabolic trough collector (PTC) are investigated. The thermodynamic and economicmodels, based on the principles of thermodynamics and heat transfer, aswell as dynamic economic analysis, are developed for the components of the combined system. By performing a parametric study, the effects of outlet temperature (T-PTC,T-out) and temperature difference between inlet and outlet of PTC (Delta T) and pinch point temperature difference of heat exchangers on the thermo-economic performance are evaluated. Moreover, under reasonable thermodynamic boundary conditions, the optimal operational parameters are obtained via a Pareto frontier solution. It is indicated that the improving TPTC, out is beneficial to the thermo-economic performance. Among the fluid candidates, toluene yields the best energy, exergetic and economic performance. There exists an optimal Delta T at which the thermal and exergy efficiency achieve the maximum. The optimal Delta T is 19-26 degrees C for the screened working fluids. The pinch point temperature difference of evaporator has different impact on the system performance compared with that of condenser. The evaporator pinch point temperature difference has slight influence on the economic performance when it is larger than 10 degrees C. While there is optimized condenser pinch point temperature difference (7-8 degrees C), the economic performance is the optimal. The PTC and heat exchanger are the main source of total investment cost, account for more than 75%. The Pareto frontier solutions can provide a design guide for the decision maker.
