Abstract—This paper presents the efficiencies such as exergy, thermal, solar power cycle efficiency, along with solar heat input and area of the solar collector for 4 selected working fluids. Thermodynamic modeling was carried out using a commercial scroll expander, two compact heat exchangers, a diaphragm pump and a solar collector. The commercial software Engineering Equation Solver (EES) was used for calculating the parameters of various working fluids. The analyzed working fluids have been recommended for solar ORC. Furthermore, the economic analysis of solar powered ORC system has been carried out with the solar collector cost and the overall ORC cost of each working fluid in the system. Finally the payback period has been calculated and was around 3.7 years.
Index Terms—Economic analysis, organic Rankine cycle, solar collector, thermal efficiency.
