Thermomagnetics of active magnetic regenerators

制冷是一项普及技术，可提高工业化经济体的生活水平;一个例子是通过保存食品和药品延长预期寿命。制冷循环也存在于工业过程中，如气体液化，空气分离，冷却器和空调。天然气和氢气等低温燃料也突出了对高效低温制冷机和制冷机的需求。提高效率和使用无害工作物质是替代制冷技术发展的两个主要驱动力。

Refrigeration is a pervasive technology enabling high standards of living in industrialized economies; an example being increased life expectancies through the preservation of food and medicines. Refrigeration cycles are also found in industrial processes such as gas liquefaction, air separation, chillers, and air-conditioners. Cryofuels such as natural gas and hydrogen also highlight the need for efficient cryogenic refrigerators and liquefiers. Higher efficiencies and the use of benign working substances are two of the primary drivers for the development of alternative refrigeration technologies.
