Abstract
A computer model was developed to perform a thermodynamic analysis of the transcritical carbon dioxide cycle with two-stage compression and intercooling. In typical two-stage compression with intercooling applications, the intercooler serves the purpose of cooling the fluid to the lowest possible temperature before it enters the second-stage compressor. This paper presents the results of the system analysis of the transcritical carbon dioxide cycle with two-stage compression and intercooling (intercooler cycle) and identifies the pressure ratios that provide maximum system efficiency. The results show that the coefficient of performance (COP), curves of the intercooler cycle are different from the ‘typical bell curve behaviours’ that are observed when plotting the COP versus the intermediate pressure with assumptions of isentropic and real compression process.
