Refrigerators are an important household item that comes under the category of cooling appliances. The primary structure of the refrigerator consists of a thermally insulated compartment which provides a mechanism that lowers the temperature inside it and transfers the heat from the inside to the external environment. As it keeps the temperature low as per user requirement, it is used to preserve the food items that can be spoiled at ambient temperature. Refrigerators in available in many sizes on the market but they have some limitations for indoor usage only as they require electricity and are in large amounts. However, when people are more moving towards outdoor activities, they need to have a refrigerator to keep the necessary items which will prevent spoilage and wastage. So, this paperwork has designed a mini refrigerator that is powered by batteries and is portable which can be easily used outdoors as well. This paper deals with the working of small-size refrigerators. Thermoelectric Cooler Design is to be used as an aid in the design of thermoelectric cooler devices. This work is used to quickly model and compare alternative designs. An optimum coefficient of performance and heat pumping can be quickly determined. Other major features include the ability to change the material properties and dimensions of couples.
