تحلیل ترمودینامیکی و اقتصادی یک سیستم تولید چندگانه نوین ترکیب‌شده با ذخیره انرژی هوای فشرده و سیستم سرمایش اجکتوری مبتنی بر گوگرد دی‌اکسید

A novel compressed air energy storage system integrated with combined cooling, heating and power is proposed and investigated in this study. The system under study uses sulfur dioxide as the working fluid under the ejector refrigeration system to produce coolant, which has not been used in previous studies, and the waste heat is recovered and stored in the compressed air storage device, which shows the innovative aspect of the present study. A complete and comprehensive thermodynamic and economic analysis is performed on the proposed system. The proposed system is examined from different perspectives and the system performance is quantified through output parameters. Using up-to-date cost functions, the studied system is examined from an economic perspective to clearly demonstrate the cost-effectiveness of the proposed system. In addition, a parametric analysis is performed to evaluate the system behavior by changing key parameters under different operating conditions. The results of the thermodynamic analysis indicate the optimal thermodynamic performance of the proposed system, such that an energy efficiency of 21% and an exergy efficiency of 55% are achieved for the studied system. In addition, an economic analysis yields a total system cost of 232$ per gigajoule.
