摘　　要：建立双级内可逆卡诺制冷机模型 ,应用有限时间热力学理论 ,导出制冷系数与制冷率间的基本优化关系 ,给出其生态学优化性能 ,得到一些新的性能参数 ,并作些有意义的讨论 ,所得结论可供制冷机的最佳工作状态选择和优化设计提供些新理论指导 .A mode of the two grade endoreversible Carnot refrigerator is established. Based on the finite time thermodynamics theory, the fundamental optimum relation between the coefficient of performance and the cooling rate is derived. The ecological optimal performance are obtained, and some meaningful conclusion are also discussed. The results obtained here may be used as a reference in the selection of the optimal working condition and optimal design of the refrigerator.
