Portable Refrigeration Control System

Abstract

This paper describes tests of a Refrigeration system that developed based on Peltier systems. We have long used fridges for cooling food items. Fridges use a cooling system that are bulky and costly and thus we cannot create small fridges for limited cooling needs. Well hereby we make use of Thermoelectric cooler (peltier) based cooling to create a mini fridge that can cool cans as well as small food packets and items. The system makes use of 4peltier modules with a thermal insulation frame and electronic circuitry to develop the system. Peltiers allow for instant cooling using electricity at lower costs. Thermoelectric coolers operate according to the Peltier effect. The effect creates a temperature difference by transferring heat between two electrical junctions. A voltage is applied across joined conductors to create an electric current. When the current flows through the junctions of the two conductors, heat is removed at one junction and cooling occurs. Heat is deposited at the other junction.So here we propose a mini can cooler fridge that can cool cold drink cans easily. Our system uses peltier, along with heat sink, power supply and insulation with outer frame to achieve this system. We develop a customized casing to ensure we get peltier cooling on the inside while the heatsink and fan can throw the generated heat outside. We use insulation to achieve as much thermal insulation as possible
