Composite material based on LaFe(Co, Si) for active magnetic regenerator operating near room temperature

The aim of this paper is to propose a composite material based on compounds of LaFeCoSi operated in temperature range 275-315K. The composite material was designed according to the optimum composite fractions, which were determined numerically. A force of approximately 100 kN was applied to the assemblies of the composite elements to obtain a homogeneous disk. A direct measurement of the adiabatic temperature change under magnetic field of 2T has been carried out by the test bench built at Heig-VD. The comparison results between the numerical prediction and experimental of the magnetocaloric effect has been presented and discussed to validate the proposed model.
