Summary

Analysis of an endoreversible two-stage cascade cycle has been implemented and optimum intermediate temperature for maximum exergy and refrigeration effect have been obtained analytically. Further, the heat reservoir temperatures has been optimised independently. A comprehensive numerical model of a transcritical CO2-C3H8 cascade system was developed with intent to verify the theoretical results. It is seen that the simulation results agree well for the optimal low-temperature reservoir but deviate modestly from the theoretical optimum of the high-temperature reservoir (TH). It has also been observed that system performance improves as TH increases and unlike theoretical predictions, no optimal TH is present within feasible working temperatures.
