A Refrigerator without Compressor Powered by Solar Energy

Abstract

Thermoelectric refrigerator with an inner volume of 10 litre (approx.) has been designed and tested, whose cold system is composed of a Peltier and a fan (i.e. heat sink).Analysis of a its performance in different conditions has been carried out with this prototype.
Thermoelectric devices are capable of converting electrical energy into thermal heat pumping at a very high efficiency.The cooling system is made up of one thermoelectric device, composed of a Peltier module (40 watt) with its hot side in contact with a heat sink and aluminum plate in contact with the cold side.
