摘　　要：给出了一种铁电埃里克森制冷机模型 ,利用铁电晶体的热力学性质 ,应用有限时间热力学理论 ,探讨热阻及非理想回热对一类铁电埃里克森制冷机的影响 。A model of ferroeletric Ericsson refrigerator has been worked out.By using the finite time thermodynamics and the thermodynamic properties of a ferroelectic,the effect of thermal resistances and nonperfect regeneration on a class of ferroeletric Ericsson refrigerators is studied.The results obtained here may provide some new theoretical guidance for the development and optimal design of ferroelectric Ericsson refrigrators.
