Magnetic refrigeration technology, as a new type of refrigeration, is gradually leading the green refrigeration revolution. It utilizes the magneto-thermal effect of magnetic materials to realize refrigeration through magnetic field changes, which has the advantages of high efficiency, environmental protection and low noise. Compared with traditional refrigeration technology, magnetic refrigeration technology can significantly reduce energy consumption and greenhouse gas emissions, applicable to air conditioners, refrigerators and other refrigeration equipment. With the progress of material science and refrigeration technology, magnetic refrigeration technology is expected to become one of the mainstream technologies in the refrigeration industry in the future.
