Thermoeconomic analysis of a novel ejector cooling based multi generation system combined with compressed air energy storage

This study proposes and investigates a novel compressed air energy storage (CAES) system integrated with combined cooling, heating, and power (CCHP). The system utilizes sulfur dioxide as the working fluid in its cogeneration unit, generating coolant via an ejector cooling and heating subsystem. A comprehensive thermodynamic and thermo-economic analysis is presented, evaluating the system's performance through key output parameters. The system was evaluated through a case study to assess its performance in a specific context. A sensitivity analysis was also conducted to understand the system's behavior under different conditions. Thermodynamic analysis demonstrated an energy efficiency of 21% and an exergy efficiency of 55%. Economic analysis determined the total cost of the system to be $232/GJ. This work has the potential to contribute a new methodology for improving the thermodynamic performance of multi-generation systems.
