为打破室温磁制冷与磁热泵系统在室温附近的应用瓶颈,本文建立了复叠式主动磁回热器一维数值模型,从制热性能的角度探究其关键影响参数。仿真结果表明:换热流体流量越大,热端温度越快达到稳态,且无负荷温跨随流量先增大后减小,制热量随流量的增大而增大。此外,缩短加退磁和流动时间可显著提升制热量及无负荷温跨,在1-1-1-1 s运行时序下,最高分别可达55.2 W和29.9 K。当LaFeSiH居里温度间隔增大时,无负荷温跨先增大后减小,最大值在居里温度间隔为6 K时取得,为40.2 K。在4种填充长度比例中,制热性能最好的比例是2:2:2:2:7,其最大无负荷温跨为31.2 K,最大制热量可达64 W。本文的研究对拓宽室温磁制冷及磁热泵的应用范围有较重要的研究意义。
To address the limitations of magnetic refrigeration and magnetic heat pump systems near room temperature
this paper establishes a one-dimensional numerical model of a cascade active magnetic regenerator and examines its key influencing parameters on heating performance. Simulation results indicate that a higher flow rate of the heat transfer fluid accelerates the attainment of a steady-state temperature at the hot end. Furthermore
with the flow rate increases
the no-load temperature span initially increases and then decreases
while the heating capacity increases. Additionally
reducing the (de)magnetization time
as well as the flow time
can significantly enhance both heating capacity and no-load temperature span
achieving values of up to 55.2 W and 29.9 K
respectively
under a 1-1-1-1 s operating sequence. When the Curie temperature interval of LaFeSiH increases
the no-load temperature span first increases and then decreases
reaching a maximum of 40.2 K when the Curie temperature interval is 6 K. Among four filling length ratios
the optimal heating performance is achieved with a ratio of 2:2:2:2:7
resulting in a maximum no-load temperature span of 31.2 K and a maximum heating capacity of 64 W. This study is of significant research importance for expanding the application scope of magnetic refrigeration and magnetic heat pumps.
