Cooling and Heating of Refrigerator Jacket by Using Peltier Effect

Abstract

This project outlines the implementation of photo voltaic driven cooling and heating system. Refrigerator jacket works according to the atmospheric conditions. If the atmosphere is cooler than the required condition, then it gives the amount of warmness to the human body, without causing any side effects and vice versa. Refrigerator jacket entirely depends upon the principle of “Peltier effect”. Refrigerator jacket simply uses electrons rather than refrigerants as a heat carrier. This cooling or heating system does not contain any moving parts like compressor or solution pumps and also it does not require any condenser, expansion valve, or absorber. So, its design is simple and easy to construct. In this project, the working model of jacket utilises the required thermo electric modules. The performance of this model is experimentally evaluated with copper cabinet. The present article explains about how Peltier cooler is used in jacket and its advantages over conventional cooling system. Refrigerator jacket reduces the use of convectional refrigeration system, therefore effect of skin cancer, ozone depletion potential, and global warming potential reduces. This jacket is compact in size and it is eco-friendly in nature. Because of all these reasons Peltier effect is used in refrigerator jacket. Function of jacket interface is to provide thermal efficiency and comfort to user. Peltier cooling module is used to cool fluids stored in reservoir. Thermal resistance and cooling jacket size slightly decrease the Peltier cooling capacity on human.
