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
CFC’s. Some of the equipments which cause this effect are 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.
Here we are using Micro controller (AT89S52) allows dynamic and faster control.
Liquid crystal display (LCD) makes the system user-friendly. The sensed and set
temperature values are simultaneously displayed on the LCD panel.
In this project we are using solar panels for charging a Lead Acid Battery (12V,
1.2 Amp hrs), a pelteir thermoelectric device which when connected to battery generates
cooling effect on one side and heat is dissipated on other side through heat sink, a cooling
fan is used for dissipating the heat from the heat sink.
This project uses regulated 5V; 500mA power supply. A 7805 three terminal
voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to
rectify the ac out put of secondary of 230/12V step down transformer.

major problem before us is depletion of ozone layer which is caused by the release of
