| Abstract: | The exergoeconomic performance of a class of universal steady-flow endoreversible heat pump cycle model consisting of one heating branch,two cooling branches and two adiabatic branches is analyzed using the theory of finite time thermodynamics.The analytical formulae about the profit rate and COP versus temperature ratio of the cycle model are derived.The profit rate versus COP characteristics are obtained by numerical examples.The results obtained herein include the performance characteristics of endorever... |
