摘要：

This research presents the optimization and performance analysis for irreversible heat pumps operating with reversed Brayton cycle with constant-temperature heat reservoirs via finite-time thermodynamics (FIT) by considering exergetic efficiency as the optimization objective combining exergy model. Moreover, two different strategies in the process of multi-objective optimization are proposed, and the outcomes of each strategy are evaluated separately. The first strategy is proposed to maximize the coefficient of performance (COP), the ecological coefficient of performance (ECOP) and the exergetic efficiency. Furthermore, the second strategy is suggested to maximize the COP, ECOP and Ecological function. All the strategies in the present work are executed via the multi objective evolutionary algorithms based on NSGA parallel to method. Finally, to govern the final answer in each strategy, three efficient decision makers were executed. (C) 2015 Elsevier Ltd. All rights reserved.
