Abstract

The following paper presents a thermodynamic analysis of a CSP (Concentrated Solar Power) plant that works with ORC; electric power is always approximately equal to 20 kWe. Through thermodynamic optimizations were compared, for various working fluids(R134a, R245fa, Acetone), the results in terms of ɳgel and absorbing mirrors

surface; for the same electrical power. For the systems that works with acetone, it also provided for the study of the selection of the most suitable machines to the thermodynamic cycle under consideration. We highlight the construction simplicity of the ORC systems and greater efficiency for lower ratio of the temperature difference.
