Abstract:

 In this paper, energy and exergy analyses of a solar assisted Organic Rankine Cycle using R245fa as working fluid is carried out for production of power. The proposed cycle is an integration of solar-sub system using heliostat and central receiver and Organic Rankine Cycle. Energy destruction rate in each component of the cycle is determined to identify the realistic performance of the cycle along with causes and locations of thermodynamic imperfection. Duratherm 600 oil is used as a heat transfer fluid in solar-sub system. After analysis it is observed that the highest exergy destruction takes place in central receiver 52.5%, heliostat field 25%, HRVG 5.5%, and condenser 2.55%. The energy efficiency is 9.95% and exergy efficiency is 10.66% are observed.
