DESIGN AND ANALYSIS THERMOELECTRIC REFRIGERATOR

Abstract

In Today’s world global warming is being increasing year by year. There are many reasons
like pollution, deforestation, water contamination, etc...In coming years the major problem before us is
depletion of ozone layer which is caused by the release of CFC’s. Some of the equipment which causes
this effect is refrigerators, AC’s. In this project we are mainly focusing on a solution to control this
problem we have focused on refrigerators which releases CFC’s. Here we are designing a mini solar
based refrigerator which is cheaper as well as eco-friendly. In this project we are using solar panels for
charging a Lead Acid Battery (12V, 1.2 Amp hrs), a peltier thermoelectric device when connected to
battery generates cool effect and hot effects depending on the mode required by the user. Since we are
using this for fridge we need only cool mode. A peltier thermoelectric device is connected to the battery
to generate cooling effect. We need to display the voltage for that we are using ADC which is given to the
controller. For this ADC we are giving a clock pulses through 555 timers to perform its operation. The
aim of the project is to design and analyze a compressor less refrigerator system. A parametric model of
the refrigerator is designed using 3D modeling software Catia and analyzes using Ansys Software. Catia
is the standard in 3D product design, featuring industry-leading productivity tools that promote best
practices in design.
