摘要： An air cooling-type refrigeration device includes a device body, an air cooling system attached to the device body, and a drawer which may be pulled out relative to the device body, the drawer being capable of receiving cold air provided by the air cooling system, so as to cool an object stored in the drawer. The air cooling-type refrigeration device further comprises a magnetic field generating apparatus and a detection apparatus. When the magnetic field generating apparatus is powered on, a magnetic field acting on the object stored in the drawer is generated. The detection apparatus is used to detect whether the drawer is pulled out. The magnetic field generating apparatus and the detection apparatus are configured such that the magnetic field generating apparatus is powered off when the detection apparatus detects that the drawer is pulled out.

摘要： The invention relates to a magnetocaloric generator includes a set of porous active elements based of MCM materials, and a magnetic arrangement. The magnetic arrangement includes two superposed magnetic rotors, namely an external magnetic rotor and an internal magnetic rotor delimiting an air gap between them, and includes one same number of magnetic poles. The set of active elements includes a stator disposed in said air gap. The active elements extending axially in said stator enable a two-directional axial circulation of a heat-transfer fluid between a hot end and a cold end of said generator. The external magnetic rotor is advantageously coupled, on the one hand, to an electrical machine by a mechanical coupling, and on the other hand, to said internal magnetic rotor by a magnetic coupling, such that said rotors move in one same direction of rotation and are magnetically synchronous.

摘要： A magnetic field application device applying a magnetic field to a magnetocaloric material includes: a magnetic field generating component; a first yoke connected to both poles of the magnetic field generating component; and a second yoke movably disposed between a first position and a second position. A first closed magnetic circuit formed by the magnetic field generating component and the first yoke passes through a magnetic field application region in which the magnetocaloric material is accommodated. A second closed magnetic circuit formed by the magnetic field generating component, the first yoke, and the second yoke bypasses the magnetic field application region. Magnetic resistance of the second closed magnetic circuit when the second yoke is located at the second position is smaller than the magnetic resistance of the second closed magnetic circuit when the second yoke is located at the first position.

摘要： Heat regenerators and related methods enable heat transfer in an embedded structure of a heat regenerator. The heat regenerators enable a reduction of the pressure drop due to fluid flow through the heat regenerator and consequently an increase of power density. A heat regenerator includes a housing having a primary hot heat exchanger and a primary cold heat exchanger between elements for the oscillation of a primary fluid. The secondary fluid unidirectionally flows from the heat sink into the primary cold heat exchanger. The secondary fluid exits from the primary cold heat exchanger and unidirectionally flows towards the heat source. The secondary fluid S enters the primary hot heat exchanger and exits as the unidirectional flow of the secondary fluid S of the primary hot heat exchanger towards the heat sink. Between both primary heat exchangers, the porous regenerative material is positioned as part of the regenerator.

摘要： A refrigeration system includes a refrigeration circuit and a coolant circuit separate from the refrigeration circuit. The refrigerant circuit includes a gas cooler/condenser, a receiver, and an evaporator. The coolant circuit includes a heat exchanger configured to transfer heat from a refrigerant circulating within the refrigeration circuit into a coolant circulating within the coolant circuit, a heat sink configured to remove heat from the coolant circulating within the coolant circuit, and a magnetocaloric conditioning unit configured to transfer heat from the coolant within a first fluid conduit of the coolant circuit into the coolant within a second fluid conduit of the coolant circuit. The first fluid conduit connects an outlet of the heat exchanger to an inlet of the heat sink, whereas the second fluid conduit connects an outlet of the heat sink to an inlet of the heat exchanger.

摘要： A support layer is disposed between a first layer of first electrocaloric capacitors and the second layer of second electrocaloric capacitors. The support layer has thermally conductive vias. A voltage source is configured to apply a first voltage thereby applying a first electric field to the first electrocaloric capacitors and a second voltage thereby applying a second electric field to the second electrocaloric capacitors. The first and second electric fields are complementary such that when the first and second electric fields are applied, heat is transferred through the thermally conductive vias from the first electrocaloric capacitors to the second electrocaloric capacitors or from the second electrocaloric capacitors to the first electrocaloric capacitors.

摘要： This invention relates to magnetocaloric materials comprising alloys useful for magnetic refrigeration applications. In some embodiments, the disclosed alloys may be Cerium, Neodymium, and/or Gadolinium based compositions that are fairly inexpensive, and in some cases exhibit only 2nd order magnetic phase transitions near their curie temperature, thus there are limited thermal and structural hysteresis losses. This makes these compositions attractive candidates for use in magnetic refrigeration applications. Surprisingly, the performance of the disclosed materials is similar or better to many of the known expensive rare-earth based magnetocaloric materials.
