ABSTRACT
To contribute to the development of Engineering and Technology innovations. The research work carried out in this project will help greatly in that direction. We emphasized mainly on modern methods by which a refrigerator can be operated and maintained we also included the method used in design and fabrication, assembly and arriving at knowing the safety requirement.
During the process of production of this refrigerator, cost estimate is taken into consideration with durability of materials, portability of the product was also considered.
