摘要: 应用有限时间热力学理论,对一类以理想气体为工质的二热源制冷机作统一的描述,导得制冷机的基本优化关系,并讨论了回热损失和回热时间对制冷率和制冷系数的影响.所得结果具有普遍意义,可为卡诺制冷机、斯特林制冷机、埃里克森制冷机等一类二热源机的研制和优化设计等提供新的理论指导.

Abstract: By using finite-time thermodynamic theory, unified description a characterization is made of a class of two-heat-source refrigerators using an ideal gas as working fluid is achieved. The fundamental optimal relation of the refrigerators is derived, and the effect of regenerative loss and regenerative time on the cooling rate and coefficient of performance is discussed. The results obtained here have general significance. They may provide some new theoretical guidance for the manufacture and the optimal design of a class of two-heat-source refrigerators, such as Carnot refrigerators, Stirling refrigerators, Ericsson refrigerators, and so on.

Key words: unified description, two-heat-source refrigerator, finite-time thermodynamics
