Design, Fabrication and Analysis of Thermo Electric Refrigerator

Abstract

Refrigeration is the process of removal of heat from a body at lower temperature and sending it to surroundings. The present day refrigeration devices use refrigerant gases like Freons to do refrigeration which result in release of CFCs in to atmosphere which thereby result in depletion of ozone layer. But by using Thermo electric refrigeration this impact can be reduced. This project deals with design, fabrication and analysis of Thermo electric refrigerator. This refrigerator contains thermoelectric modules, Switched mode power supply equipment, Heat sinks, exhaust fans and temperature controlling switches. This project also includes the analysis of this refrigerator. Thermo electrics has a lot of scope in refrigeration, electric generators etc.
