英文摘要:

      The optimal performances of a generalized irreversible Carnot refrigeration cycle with universal heat transfer law are studied. The research objective is exergoeconomic performance. The optimal relationships between the finite-time exergoeconomic performance bound and optimization objective are derived, and the effects of heat transfer laws, various losses and price ratio on the optimal finite-time exergoeconomic performance are analyzed. The obtained results are universal and can be a reference for the designs of practical refrigerators.
