英文摘要	一级相变材料lAfE_(11.6)SI_(1.4)是磁制冷应用中的重要磁热材料,其固有的磁滞和热滞对实际制冷循环性能有较大影响,然而现有文献对此尚未研究。本文基于考虑热滞影响的材料lAfE_(11.6)SI_(1.4)的等场热容实验数据,建立考虑热滞效应的回热ErICSSOn制冷循环,揭示热滞、非平衡回热和冷热源温度等对制冷循环主要热力学性能参量的影响,应用数值计算方法,比较了考虑热滞与否时制冷循环的净制冷量、性能系数等性能参量。研究结果能为磁制冷机循环的优化参数设计提供有益的参考。; The first order phase transition material LaFe_(11.6)Si_(1.4) is an important magnetocaloric material for magnetic refrigeration.The intrinsic magnetic and thermal hysteresis of the material have a large impact on the performance of actual refrigeration cycles.However,these influences have been rarely investigated in the literature.Based on the experimental data of the iso-field heat capacity of LaFe_(11.6)Si_(1.4) with thermal hysteresis,a regenerative Ericsson refrigeration cycle with thermal hysteresis is set up in this paper,and the effects of thermal hysteresis,non-perfect regeneration,and the temperatures of cold and heat reservoirs on the main thermodynamic parameters,including the cooling quantity,coefficient of performance(COP),and so on,of the refrigeration cycle are revealed.The net cooling quantity,COP,and other performance parameters of the refrigeration cycle with and without thermal hysteresis are compared by means of numerical value calculation.The results obtained here may provide some significant message for the optimal parameter design of magnetic refrigerator cycles.; 国家自然科学基金(No.51176160)
