Recent experimental results of first order LaFeSi-based magnetocaloric materials in an Active Magnetic Regeneration device.

Summary

Recently, a lot of progress has been made by the community to optimise the properties of LaFeSi-based alloys in order to enable their integration into prototypes for different magnetocaloric applications. In this paper we present a set of experimental results obtained with a specific layering of materials having different Curie temperatures integrated into a rotating R&D prototype. Furthermore, two types of endurance tests were performed on those materials using a separate experimental test bench. The obtained results are promising and present the basis for a possible replacement of Gd-based alloys with first order LaFeSi-based alloys to be used in our ready-to-be-deployed magnetic refrigeration systems. LaFeSi-based alloys have the potential to increase the cooling power and reduce the cost of our units due to reduced raw material costs. This is a critical factor, which will make the technology more accessible for large-scale production.
