Abstract

In the last few decades the wastage of food items is due to insufficient cold storage facilities in India. This is largely due to the high electricity costs of vapor compression refrigeration cycles. This has prompted to use the alternate refrigeration cycles. This paper is devoted to using magneto-caloric effect of ferromagnetic materials for maintaining the temperature about 280K so as to keep the perishable items preserved for some period of time. The main objective of this type of refrigeration is use of solid refrigerant called magneto caloric material. This type of material can increase or decrease the temperature when they are magnetized or demagnetized. Magnetic refrigeration systems are like traditional cooling units, but they don’t use as much electricity which make it highly efficient to be use for cold storage system. The effect of solid state refrigerants, water based heat transfer fluids increases the efficiency with minimum contribution to global warming & ozone depletion making it highly sustainable which is the need of the hour.
