Transcritical Rankine Cycle

The performances of the transcritical Rankine cycles using R41 and CO2 as working fluids for power generation with lower temperature renewable energy are analyzed respectively and presented in this paper. The results show that the R41 cycle displays better comprehensive performance than that of the CO2 cycle. Compared with the CO2 cycle under the same specified conditions, the average value of the maximum net power output increased by more than 52.6%, the optimum inlet pressure decreased by over 41.6% and the second law efficiency increased by 24.8%. Moreover, the system thermal efficiency of R41 cycle is slightly higher than that of the CO2 cycle.
