Abstract The main objective of this study is to design and build refrigerator based on thermoelectric modules. The refrigerator could be used to store perishable items and facilitate the transportation of medicine as well as biological materials. The design is based on peltier effect to create hot side and cold side. The cold side is used for refrigeration purpose and hot side is for rejection of heat to the atmosphere. Multistage TEC refrigerator gives larger temperature difference in source and sink than

By applying a low voltage current (DC) power to a thermoelectric module, heat will be moved through the module from one side to the other. One module face, therefore, will be cooled while the opposite face simultaneously is heated. Both thermoelectric refrigerators and mechanical refrigerators are governed by the same fundamental laws of thermodynamics and both refrigeration systems; although considerably different in form, function in accordance with the same principles. In a mechanical refrigeration unit, a compressor raises the pressure of a refrigerant and circulates the refrigerant through the

Nikam, Dr. Jitendra A. Hole (2014) according to their study, In recent years, with the increase awareness towards environmental degradation due to the production, use and disposal of (CFCs) and Hydro Chlorofluorocarbons (HCFCs) as heat carrier fluids in conventional refrigeration and air conditioning systems has become a subject of great concern and resulted in extensive research into development of novel refrigeration and space conditioning technologies. Thermoelectric cooling provides a promising alternative R&AC technology due to their distinct advantages. Use of Thermoelectric effect to increase the COP of existing cooling system has been also reviewed in this
