ENERGY SAVINGS IN DOMESTIC REFRIGERATOR USING TWO THERMOELECTRIC MODULES& WATER COOLING OF CONDENSER

The study deals with hybrid refrigerator that combi nes thermoelectric (TER) and vapor compression refrigeration (VCR) and also entail exp erimental details of combined VCR & TER system. Objective is to configure hybrid refrig erator by introducing two Peltier modules (TER) in domestic refrigerator and to analyze compr essor cycles of conventional refrigerator with TER to increase energy efficiency of vapor com pression cycle. For this comparison of standalone VCR and Hybrid VCR+TER system is carried out. A Peltier module of size 4cm � 4cm � .4cm is introduced in the refrigerator cabinet & t he effect on energy efficiency in terms of trip time of compressor is recorded. The e ffect of Air cooled & Water cooled condenser with TER in different structures is also investigated. It is observed that by introducing thermoelectric effect,energy consumpti on of VCR is reduced by almost 10.92% annually,which accounts for 80 units per year. Thu s ultimately improving COP of the hybrid system with better control on temperature over the total run time.
