Eco Friendly CFC Less Refrigerating/Air Conditioning System

Abstract

Normally, We are using refrigerating system to store the foods, Medicines..etc to extend the lives of the products. But in the existing refrigerating system which causes cooling effect with the help of refrigerants like CFC’s,HCFC’s. They are the harmful components which causes environmental Degradation. In order to overcome this we are using peltier concepts for refrigeration and protecting the environment. In this project to introduce a portable refrigeration using peltier Element. In peltier element when given DC supply produces cooling effect on one closed surface and heating effect on another surface. The cooling effect on one surface is circulated using a fan. The heat from the hotter side is sink in the heat exchanger is removed using circulating coolant or using fan. A 230V AC supply is step down using a Transformer and Rectified using a Bridge rectifier and given as a Input to the Buck converter. The Buck Converter supplies variable DC supply to the Thermo Electric Generator. The main advantage of this system is eco friendly and simplified system with reliable control.
