Abstract: This paper examines and presents the working of solar refrigerator based on thermo electric cooling and Peltier effect. Like other countries of GCC, the UAE realizes that it has to rely less on oil and gas and start to consider other sources of energy for power production. Solar energy has been one of the most important renewable resources of energy that has been lately used for generating electricity. But amount of electricity generated from these solar panel systems is not enough for efficiently controlling a device. The aim of my work here is to use this solar energy, not to generate electricity but to directly convert solar heat applied on one side of the surface of the thermo electric element into refrigeration effect on the other side, based on peltier effect and thermo electric cooling. The main principle of the solar refrigerator is to produce a positive and negative temperature effects on its either junctions by supplying an electrical voltage with extra heat available on the plate through solar heat to generate a cooling effect. Thermoelectric cooling systems have advantages over conventional cooling devices, such as compact in size, light in weight, high reliability, no mechanical moving parts and no working fluid.
