Construction and performance test of refrigerator working on vapor compression refrigeration cycle.

Abstract

Refrigerators are considered to be an important household item that falls under the category of cooling appliances. The basic structure of the refrigerator consists of a thermally insulated compartment which through a proper mechanism lowers down the temperature inside it and transfers the heat from inside to the external environment. As it keeps the temperature lower so it is used to keep and store the food items which can be spoiled at ambient temperature. Refrigerators in almost all the sizes are available at the market but they are restricted and limited for indoor usage only as they require electricity and are large. But presently, people are more inclined towards outdoor activities and they need to have a refrigerator to keep the essential items saved from spoilage and wastage. So, this project has designed a mini refrigerator that is powered through the batteries and is portable which can be easily used outdoors as well.
