Energy, exergy, and economic (3E) analyses and multi-objective optimization of a cascade absorption refrigeration system for low-grade waste heat recovery

In the present study, an innovative cascade absorption refrigeration (CAR) system for recovering low-grade waste heat is proposed. Based on the simulation results, the energy, exergy and economic (3E) analyses of the cascade refrigeration system have been conducted. The analysis results show that there is a contradiction between economic performance and thermodynamic performance. Then, the optimization scheme aiming at total exergy destruction...
