movable refrigerator

In active magnetic regenerative refrigerators (AMRRs),the magnetic power consumption based on thermodynamic calculation can be erroneous due to the varying temperature gradient inside active magnetic regenerator (AMR) bed,unsymmetrical magnetic field distribution,length difference between AMR and magnet gas gap,and the phase between different AMRs.

在主动式磁回热制冷机中,由于温跨变化、磁场分布不对称、磁回热器和永磁体气隙长度不一致、磁回热器间相位的影响,采用热力学方法来计算磁功耗会产生较大的误差。
