Abstracts: Refrigeration is the process of removing heat from an enclosed space, or from a substance, and moving it to a place where it is unobjectionable.This work is traditionally done by mechanical work but can also be done by magnetism, laser or other means. The objective of this project is to study the magnetic refrigeration which uses solid material as a refrigerant. These materials demonstrate the unique property known as magneto caloric effect, which means that they increase and decrease in temperature when magnetized/demagnetized. This effect has been observed for many years and was used for cooling near zero temperature. The combination of solid state refrigerants, water based heat transfer fluid and high efficiency leads to environmentally desirable products with minimum contribution to global warming. Among the numerous application refrigeration technology is used for air conditioning application which provide the largest aggregate cooling power and uses electric energy
