Thermodynamic Optimization of the Organic Rankine Cycle in a Concentrating Photovoltaic/Thermal Power Generation System

Abstract:

The selection criteria of working fluids for solar thermal organic Rankine cycle and the features of R245fa as a working fluid are analyzed. A thermodynamic analysis of photovoltaic / thermal organic Rankine cycle system and the influence of evaporation temperature of working fluid in the evaporator coupled with solar panels are conducted. The results show that the performance of the solar photovoltaic/thermal organic Rankine cycle can be improved by optimizing the evaporation temperature, and 130°C is an appropriate evaporation temperature.
