Optimal performance of an irreversible, heat engine-driven, combined vapor compression and absorption refrigerator

By employing finite-time thermodynamic approach, the optimum performance of an Airreversible heat engine-driven combined vapor compression and absorption Arefrigerator system is investigated. To get closer to real machines, the effects of thermal Aresistances and internal irreversibilities on the performance of the combined Acycle is considered. The analysis show that the combined cycle has a Asignificant increase in system performance over the heat engine-driven vapor-Acompression refrigerators. (c) 1999 Elsevier Science Ltd.
