摘　　要：基于玻色气体的热力学性质和回热式布雷顿制冷循环的不可逆模型,导出循环的一些重要性能参数,如循环的制冷量、回热量、输入功和性能系数的一般表达式。通过数值计算获得了循环的一些重要的性能特性曲线,分析了循环的不可逆性和回热特性对玻色布雷顿制冷机性能的影响。Based on the thermodynamic properties of an ideal Bose gas and the model of an irreversible regenerative Brayton refrigeration cycle, the expressions for some important performance parameters of the cycle, such as the refrigeration load, regenerative heat load, work input and coefficient of performance were derived. By using numerical calculation, several important performance characteristic curves were generated. The influence of the quantum degeneracy,irreversibility and regeneration on the performance of a Bose Brayton refrigeration cycle was analyzed.
