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 Freon’s to do refrigeration which result in release of CFC sin 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 electric has a lot of scope in refrigeration, electric generators etc. This chapter recalls the general principles and main formulations useful in the study of thermoelectric coolers. Starting from the general heat diffusion equation, analytical expressions are introduced for the determination of cooling capacity and rate of heat rejection in steady-state conditions. When dealing with the whole refrigeration system, the limits of the steady-state analysis of the individual thermoelectric elements are pointed out, indicating the need for transient analysis supported by experimental evaluations. Then, the energy indicators are illustrated by considering the electrical power consumption, the thermal performance described by the dimension -less figure of merit, as well as the coefficient of performance. Furthermore, the main methods to enhance the thermoelectric cooler performance in refrigeration units are highlighted, with reference to high-performance materials, design aspects and temperature control systems. Finally, indications are reported on some applications of various thermometric refrigeration solutions, considering the technical aspects of the performance of these systems.
