摘 要:
时采用主动式磁蓄冷器（AMR）的室温磁制冷机的工作进行了模拟计算，给出不同工作温区、不同磁场强度、不同换热流体时机器的制冷能力变化、COP及热力学完善度变化趋势的预测，并对在固定周期式和可变周期式下运行时的情况进行了对比，后者的制冷能力、COP及热力学完善度都优于前者。[著者文摘]

Abstract:
A numerical model of a room temperature active magnetic regenerative refrigerator is presented. Cooling capacity, coefficient of performance and thermal cycle efficiency were predicted and analyzed under different working temperature spans, intensities of magnetic field and heat transfer fluids. Performances were also compared between the operation in fixed cycle and the operation in variable cycle. The result indicates that the latter is more desirable than the former.[著者文摘]
