Magnetic Cooling

Mechanical Engineering

The effort of this project is to perform and examine the Magnetic Refrigeration which uses solid materials as the 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 absolute zero. Recently materials are being developed which have sufficient temperature and entropy change to make them useful for a wide range temperature applications. Magnetic refrigeration is an emerging technology that exploits the magneto caloric effect found in solid state refrigerants. The combination of solid-state refrigerants, water based heat transfer fluids and efficiency leads to environmentally desirable products with minimal contribution to global warming. Among the numerous application of refrigeration technology air conditioning applications provide the largest aggregate cooling power and use of the greatest quantity of electric energy.
