The Potential Utilization of Solar Energy using Organic Rankine Cycle In Hungary

The organic Rankine cycle (ORC) is a promising proposal for creating clean energy in distant regions at a low cost by utilizing solar energy in low-medium temperature systems. The ORC system may be powered by the quantity of solar energy available in Hungary. A parabolic through collector (PTC) solar collector is utilized in this study to transform solar thermal energy into a heat stream that is used to boil the R245fa working fluid, which was chosen as a good ORC working fluid because to its low boiling point, low ODP, and low GWP value. Many recent research have looked at solar-ORC from both a theoretical and experimental standpoint in a variety of disciplines, including design systems. The basic design that eliminates the requirement for solar-ORC will be extended in this study, which will include an energy analysis, system efficiency, and turboexpander characteristics utilizing different pinch temperatures (10 °C and 5 °C). For computations in the PTC solar collector, the weather data from June is used as the starting data input. When comparing the energy from the turbine and the thermal efficiency of the ORC system with 5 °C to the ORC system with 10 °C, the result shows that the ORC system with 5 °C has a better outcome.
