Experimental Investigation on Periodical Temperature Field in Active Magnetic Regenerator of Rotary Magnetic Refrigerator

  • 摘要: 采用测量主动式回热器温度场的方法,探讨了周期性瞬态内热源作用下的多孔介质与单相流体的换热规律.实验结果表明:旋转式磁制冷机主动式回热器内温度场波动频率与磁制冷机转动频率相等.当制冷机转速增大时,温度场的波动频率相应增加,工质轮整体的温度降低,加磁区与去磁区温度场的波动频率相等,两磁区的波动相位移近似为180°去磁区温度场振幅是加磁区温度场波动振幅的2倍左右.但是当流量增大到2.639×10-4m3/s时,温度趋于饱和,设计时应选择低于临界换热介质的流量.
