| Abstract: | Performance analysis and optimization of universal endoreversible steady-flow refrigeration cycle has been performed using finite time thermodynamics. The analytical formulae about cooling load, COP, exergy loss rate, exergy output rate and ecological function of the endoreversible universal steady-flow refrigeration cycle consisting of one heating branch, one cooling branch and two adiabatic branches with heat resistance loss are derived. The influence of cycle processes on the performance of the cycle is analyzed by detail numerical examples. The results obtained herein includes the performance characteristic of endoreversible Carnot, Diesel, Otto, Atkinson and Brayton refrigeration cycles. |
