Thermoelectric module has the ability to reduce the temperature of a refrigerator box made of acrylic and further insulated by Styrofoam. This reduction of temperature is made possible by the Peltier effect from the thermoelectric module. As normal refrigerator would require a compressor motor and coolant which make the refrigerator bulky and environmentally unfriendly, thus, the aim of this project is to construct a thermoelectric refrigerator is portable and environmentally friendly with just thermoelectric module, heat sink and fans. In this project, a temperature of 13.7˚C inside the refrigerator box is achieved by running two thermoelectric modules with a 8.5V supply and a total current supply of 6.99A. This would amount to a total power of 59.415W for the two modules. The heat load that is being absorbed out would be 25.966W. Thus, it gives a coefficient of performance of 0.4370.
