Fabrication of Compressorless Solar Energy Refrigerator

[computer science topics]

Abstract

:

Refrigerator is the machine used to produce and maintain temp below that of the ambient temperature. The compressor less solar energy refrigerator works on the peltier effect by using photovoltaic cells. The photovoltaic module in the array converts sunlight into the electricity which helps in the charging of the battery. The rechargeable batteries are used to store electric energy for use during unavailability of the sunlight in the night or during poor weather. Peltier effect creates a heat difference from an electric voltage. It occurs when a current is passed through two dissimilar metals that are connected to each other by two junctions (peltier junction).The current derives a transfer of heat from one junction to the other, one junction cools off while the other heats up. The cooling junction can be used as refrigerator which will absorb the heat from the desired space.
