Abstracts: Thermoelectric Refrigeration aims at providing cooling effect by using thermoelectric effects rather than the more prevalent conventional methods like those using the ‘vapour compression cycle’ or the ‘gas compression cycle’. In this project, we have tried to develop a small capacity thermoelectric cooler, which mainly consists of thermoelectric module, Heat sink for removal of heat , 12 volt DC brushless Fan. We have made or purchased all these things at economical cost and have done the assembly to make cooler. Wherever joining is required we have used soldering and Thermal paste. Our purpose is to find COP of this system at varied condition of power supply. We had used power regulation box to give required voltage to cooler. For the measurement of temperature we have made homemade thermocouple with Digital Multimeter(DMM). We had taken around 4 readings for different power supply and made the performance curve for the model. Thermoelectrics and thermoelectric cooling are being studied exhaustively for the past several years and various conclusions have been conceived regarding the efficient functioning of thermoelectric refrigerators.
