Summary

It was found that, compared with the conventional transcritical CO2 cycle and ejector-expansion transcritical CO2 cycle, the simulation results show that the coefficient of performance and second law efficiency of the new cycle were increased by about 55.5 and 26%, respectively, under the operating conditions that evaporator temperature is 10°C; gas cooler outlet temperature is 40°C and gas cooler pressure is optimum pressure.
