Thermodynamic Study of a Combined Power and Refrigeration System for Low-Grade Heat Energy Source

This study focuses on the thermal performance analysis of an organic Rankine cycle powered vapor compression refrigeration for a set working fluids each cycle, also known as dual fluid system. Both cycles are coupled using common shaft to maintain constant transmission ratio one. Eight have been studied and total sixty-four combinations analyzed combined The has performed achieve temperature −16 °C condenser temperatures 34 °C, 36 38 40 °C. For desired in required work input, mass flow rate, heat input were determined systematically. Based manifestation criteria, three (R123, R134a, R245fa) chosen two (Propane picked cycle. Further, combination R123 with propane was scrutinized their highest efficiency value 16.48% corresponding coefficient 2.85 at
