Self-Heat Recuperation Using Magnetocaloric Effect

Chemical Engineering Transactions, 2012
Recently, self-heat recuperation using a magnetic heat circulator for thermal processes that uses liquids as their process stream has been proposed. In the heat circulator, the heat exergy of the process stream is recuperated by magnetocaloric effect of ...

A Solid-to-Solid 2D Model of a Magnetocaloric Cooler with Thermal Diodes: A Sustainable Way for Refrigerating

Energies, 2023
Solid-state caloric cooling is a viable route toward a more sustainable way of refrigerating. The refrigerants are solid-state materials with a caloric effect detectable by measuring a temperature variation through an external-field intensity change. The

Study of magnetocaloric effect in half-metallic ferromagnet Co3Sn2S2

Results in Physics, 2018
We have investigated the magnetocaloric effect of a shandite-type half-metal ferromagnet Co3Sn2S2. The magnetic entropy change -ΔSM(T,H) can be well scaled by the scaling relations, indicating that the magnetic ordering transition is of second order. The

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...
