Abstract
A heat pump includes a magnet assembly which creates a magnetic field, and a regenerator housing which includes a body defining a plurality of chambers, each of the plurality of chambers extending along a transverse direction orthogonal to the vertical direction. The heat pump further includes a plurality of stages, each of the plurality of stages including a magnetocaloric material disposed within one of the plurality of chambers and extending along the transverse direction between a first end and a second end.
Claims20
A heat pump, comprising:
- a magnet assembly, the magnet assembly comprising a first magnet and a second magnet, the first magnet and the second magnet spaced apart along a vertical direction such that a gap is defined between the first magnet and the second magnet and a magnetic field is created in the gap;
- a regenerator housing, the regenerator housing comprising a body defining a plurality of chambers, each of the plurality of chambers extending along a transverse direction orthogonal to the vertical direction;
- a plurality of stages, each of the plurality of stages comprising a magnetocaloric material disposed within one of the plurality of chambers and extending along the transverse direction between a first end and a second end;
- and
- a support frame, the support frame comprising an upper frame member and a lower frame member spaced apart along the vertical direction from the upper frame member, the support frame further comprising an adjustable intermediate member disposed between the upper frame member and the lower frame member, wherein the first magnet is connected to the upper frame member and the second magnet is connected to the lower frame member, and wherein adjustment of the adjustable intermediate member adjusts a length of the gap.
