Magnetocaloric System

General Electric has developed a new cooling system based on the notion of the magnetocaloric effect. Instead of the traditional compressor, this method introduces magnets that create a magnetic field, which heats up particles in the heat exchanger. A refrigerant releases the generated head, so when the field is removed, the refrigerator cools down. Temperature can be reduced up to 80 ºF, while the systems improves efficiency by about 20% compared to a standard refrigerator and eliminates the need for chemicals that harm the environment.
