Schematic of the magnetic refrigerator prototype.
The cooling-down curves for using nitrogen and helium as heat transfer gases at 0.6 MPa and 0.6 Hz.
Temperature span at various charging helium pressures. Inset is the no-load cooling temperature and hot heat exchanger temperature at various charging helium pressures.
Cooling power at various charging helium pressures.
Cooling temperature and temperature span at various phasing. Inset is the schematic relationship between the regenerator position (applied field strength) and gas displacer position (heat transfer flow rate).
