Design And Construction Of A Refrigerator

ABSTRACT
This write up is a detail of the process and formulation of plan for the physical realization of the construction of a refrigerator. It is divided into chapter, which discussed extensively the practical refrigeration cycle with full attention given to design factors, working principle and choice of material.
The method used in construction, assembly and arriving at knowing the safety requirements were not left out.
