CONSTRUCTION OF A MOBILE REFRIGERATOR FRIDGE

By

CHIKA NNAEMEKA EBENEZER AND OTHER GROUP MEMBERS

Presented To

Department of Mechanical Engineering

This write up focuses attention on a detailed report and account on the process of construction and formulation of plan for the actual and physical realization of the construction of the project work captioned fabrication and construction of a mobile cooling system.  The report is therefore divided into chapters and each chapter discussed extensively such that an illiterate refrigerator mechanic who read and comprehends the report can easily carryout the construction of refrigerator under little guidance and supervision.
Subsequently, the principles of influencing the operation of a cooling system, choice of materials, various methods used in the fabrication and recommendation for advancement were duely treated.
Therefore, as the cooling system composed of mechanical and electric all parts, a lot of effort were made to break and discuss the various stages and sequences of assembly.  Stating a quite number of safety rules which must be adhered strictly to by and intended person or persons, who may embark on the project in future to achieve a positive result.

Finally, this write up also encompasses the maintenance of any cooling system irrespective of the size and make without limiting it to only mobile refrigerator, with due consideration that we are in the modern age of refrigeration due to the gradual destruction of the ozone layer, so that any person who seized the opportunity of reading through the report can maintain such equipment no matter the size and complexity with ease and save himself from being overheated by the sun.
