magnetic refrigeration full report

Magnetic refrigeration is an alternate method of producing refrigeration. This finds great importance now a day because of the world wide ban of environmental damaging substance like chloroflurocarbon, which is used in conventional vapor compression refrigeration. Magnetic refrigeration is based on phenomenon called magneto caloric effect. A quick review of the different stages of development made in magnetic refrigeration is done in this paper. And a proto type of magnetic refrigerator that works at room temperature is discussed .the magnetic material is cyclically magnetized and demagnetized by permanent magnets in an adiabatic process. Even water can be used as a heat exchanger and no use harmful gases. The maintenance required for magnetic refrigerator is very small compared to vapor compression refrigeration the different methods of finding magnetocaloriceffect are discussed. Different types of magnetic refrigerants that are commonly used and some of their important features are discussed.
