Magnetic Refrigeration

Modern society largely depends on readily available refrigeration methods. Up till now, the conventional vapor compression refrigerators have been mainly used for refrigeration applications. Nonetheless, the conventional refrigerators – based on gas compression and expansion – are not very efficient because the refrigeration accounts for 25% of residential and 15% of commercial power consumption due to the use of high power consuming compressors. Moreover, Conventional Refrigerators utilize ozone depleting refrigerants like Freon which release CFCs, which have a detrimental effect on our environment. This motivated us to design and fabricate a model that produces a refrigeration effect utilizing a green technology, namely Magnetic refrigeration which is a novel concept that incorporates the principle of the magneto-caloric effect and can act as a substitute for the conventional refrigerating systems. The elimination of compressors considerably reduces the power consumption and makes refrigeration a noiseless process, while the elimination of Freon makes it an environmentally friendly refrigerating technique.
