Magnetocalorics – solid-state cooling
The thermodynamic efficiency of magnetic cooling systems is significantly higher than with conventional compression cycles of traditional compressors. Cooling by means of magnets consequently reduces energy costs by up to 35% compared with the cooling and air conditioning systems known today.
Magnetocaloric materials of the manganese iron family can be used for cooling purposes because they feature special properties:
- They heat up when exposed to a magnetic field.
- When the magnetic field is removed, they cool down again.
With magnetic cooling, you do not need a conventional compressor, so the operation of refrigerators and air conditioning systems produces hardly any vibration or noise. As vibrations are reduced substantially, there is less wear and tear on the equipment. This extends the useful life of the cooling systems.
Magnetic cooling does not require any synthetic refrigerants that contribute to global warming, nor any flammable, toxic or explosive substances such as ammonia, butane or propane.
In Ludwigshafen and Rheinbach Deutsche Nanoschicht enforces the market introduction of magnetocaloric materials for efficient cooling on behalf of BASF New Business. In the Analytics and Logistics Center first large material batches of magneticaloric materials are processed.
