Abstract

In this paper, a one-dimensional transient model is constructed by using COMSOL multiphysics to investigate the single-layer, double-layer and three-layer regenerator composed of three kinds of magnetocaloric materials (a, b, c) with different Curie temperatures. The effects of different filling ratios and high temperature end temperature on the performance of active magnetic regenerators are studied. The simulation results show that when the active magnetic regenerator is uniformly filled, the performance of the three-layer regenerator is better than that of the single-layer and double-layer regenerator. When the double-layer regenerator is filled with non-uniform proportion, the performance is the best when the filling ratio is 3:7. Compared with the double-layer regenerator filled with 5:5, the cooling capacity of the regenerator filled with 3:7 ratio is increased by 6.02% and the corresponding COP is increased by 3.5%. Meanwhile, the maximum cooling capacity is increased by 1.13% compared with the three-layer AMR ( i.e. example c). In order to investigate the influence of different hot end temperature on the performance of the three regenerators, the different filling methods at different hot end temperatures have a great influence on the performance of AMR.
