摘要：

This study looks at the performance of a system that combines an organic Rankine cycle (ORC) and an ejector refrigeration cycle (ERC) using energy, conventional, and advanced exergy techniques to find ways to make it better and to see how the different parts of the system work together. The fluids selected for investigation are R245fa and R236ea as working fluids because they are widely known for dealing with waste heat from internal combustion engines. When the temperature is 150 degrees C, the power generation system claims a maximum efficiency of 9.25% to 9.8%. With a turbine expansion ratio of 5.5, the COP is 0.145. The destruction of the turbine and ejector is quite high, at 50 kW and 79 kW, respectively.
