摘　　要：用有限时间热力学方法分析了一类普适定常流内可逆制冷机循环,导出了存在传热损失时,由一个吸热过程、一个放热过程和两个绝热过程组成的一类普适的定常流内可逆制冷机循环的制冷率、制冷系数、损失率、输出率和生态学性能,并由数值计算分析了循环过程对循环性能的影响特点。所得结果包含了内可逆Carnot、Diesel、Otto、Atkinson和Brayton制冷循环的特性。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.
