5.5 A Note on the Design of Magnetocaloric Refrigeration
or Heat-Pump Devices Based on Magnetocaloric Fluids
The great advantage of magnetocaloric energy conversion based on magnetocaloric
fl
uids is in the following facts:
No moving parts;
Simpli
ed construction of magnetic
eld sources;
No need for dynamic seals or valves;
Potential application also in small or micro-sized devices.
The disadvantages of such systems relate to the rheology of magnetocaloric
fl
uids and the related pumping power consumption and the overall magnetocaloric
effect, which is reduced by the thermal mass of the base or the carrier
fl
uid.
