Magnetocaloric cooling


Technology Description

Solid state cooling alternative to vapour compression technologies. Applying an external field (magnetic fields) under adiabatic conditions leads to temperature increase of the caloric material which correspond to a change of magnetisation. On the contrary, when decreasing adiabatically the external fields, the temperature of the material decreases to lower values compared to the initial one. It exploits the properties of ferromagnetic materials to absorb or release heat from its surroundings.

Relevance for Net Zero

Estimated efficiency 25% higher compared to best available cooling technologies. Magnetocaloric is the most mature solid state technology, however, there are still limitations in permanent magnet applications.
