| Abstract: | The purpose of this paper is to present the results of a thermodynamic analysis of transcritical carbon dioxide cycles. The analysis shows that the exergetic efficiency of the transcritical carbon dioxide cycle varies nonmonotonically with the heat rejection pressure. A maximum exergetic efficiency occurs at an optimal heat rejection pressure. It is further revealed that the effect of the outlet temperature of the gas cooler, the evaperation temperature and the superheat to exergetic efficiency. |
