Active magnetic refrigerants based on Gd-Si-Ge material and refrigeration apparatus and process

Patent Gschneidner, Jr., Karl A. (Ames, IA); Pecharsky, Vitalij K [Ames, IA]

Active magnetic regenerator and method using Gd.sub.5 (Si.sub.x Ge.sub.1-x).sub.4, where x is equal to or less than 0.5, as a magnetic refrigerant that exhibits a reversible ferromagnetic/antiferromagnetic or ferromagnetic-II/ferromagnetic-I first order phase transition and extraordinary magneto-thermal properties, such as a giant magnetocaloric effect, that renders the refrigerant more efficient and useful than existing magnetic refrigerants for commercialization of magnetic regenerators. The reversible first order phase transition is tunable from approximately 30 K to approximately 290 K (near room temperature) and above by compositional adjustments. The active magnetic regenerator and method can function for refrigerating, air conditioning, and liquefying low temperaturemore » « less

Magnetic refrigeration system with separated inlet and outlet flow

Patent Auringer, Jon Jay; Boeder, Andre Michael; Chell, Jeremy Jonathan; ...

An active magnetic regenerative (AMR) refrigerator apparatus can include at least one AMR bed with a first end and a second end and a first heat exchanger (HEX) with a first end and a second end. The AMR refrigerator can also include a first pipe that fluidly connects the first end of the first HEX to the first end of the AMR bed and a second pipe that fluidly connects the second end of the first HEX to the first end of the AMR bed. The first pipe can divide into two or more sub-passages at the AMR bed. Themore » « less

Magnetic refrigeration system with unequal blows

Patent Boeder, Andre Michael; Chell, Jeremy Jonathan; Jacobs, Steven Alan; ...

A magnetic refrigeration apparatus includes beds of magnetocaloric material with a hot side and a cold side. The apparatus also includes a magnet to apply a magnetic field to the beds, a heat transfer fluid, a pump to circulate the heat transfer fluid, a hot side heat exchanger, a cold side heat exchanger, and a controller to control the flow of heat transfer fluid from the cold side to the hot side of the beds when the magnetic field on the beds is high at an average flow rate of ΦH for a duration ΔtH. The controller also controls themore » « less
