英文摘要	Conference Name:2012 2nd International Conference on Materials Engineering for Advanced Technologies, ICMEAT 2012. Conference Address: Xiamen, China. Time:December 27, 2012 - December 28, 2012.; Based on the experimental data of entropy change varying with temperature, the regenerative Brayton refrigeration cycle using Gd0.94er0.06 as the working substance is set up for magnetic field changes with 0-1T and 0-2T. By using thermodynamic analysis method, some parameters such as the non-perfect regeneration, net cooling quantity, coefficient of performance (COP), and so on, are analyzed and calculated. The effects of temperature of the heat reservoir, regeneration and external magnetic field are also discussed. The results obtained in the present paper show that the refrigeration cycle operating in TC=T0, TH= T0+7K and 0-2T magnetic field change has not only maximum cooling quantity but also maximum COP in all the established magnetic refrigeration cycles, and can provide some new guide for the optimal design of real room-temperature magnetic refrigerators. ?
