Design and Experimentation of Thermoelectric Refrigerator for Cold Storage Application

In recent years, with the increase awareness towards environmental degradation due to the production, use and discharge of Chloro Fluoro Carbons (CFCs) and Hydro Chlorofluorocarbons (HCFCs) as heat carrier fluids in conventional refrigeration systems has become a subject of great concern and resulted in extensive research into development of refrigeration technologies. Thermoelectric operated cooler provides a best alternative in refrigeration technology due to their distinct advantages. While using thermoelectric effect in system the Coefficient of Performance (COP) of the system also increases. In this paper we proposed method to increases COP of thermoelectric refrigerator and also conducting research for development of renewable energy based TER system. The TER system have been designed and developed an experimental thermoelectric refrigeration system having refrigeration space 5 lit is cooling by eight module and heat sink fan assembly for thermoelectric module to increases heat dissipation rate.The calculated COP of thermoelectric refrigeration cabinet was 0.16 with an average indoor temperature of 300C
