Description
ABSTRACT
This write up is a detail of the process and formulation of plan for the physical realization of the construction of a mobile 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.
INTRODUCTION
The role played by refrigeration to the raising of people’s standards of living cannot be over emphasized. Besides the encroachment made in refrigeration in the recent years as a result of group where engineers, Scientists, Technicians, Craftsmen etc. combine their creative abilities, skills and knowledge.
Again, science provides the foundations on which other new discovery like substances and material are built. These are applicable to refrigeration field by those the manufacture, design, maintain and install refrigeration equipment. Through subsequent planned research, development and practical applications of refrigerator theories and principles. The research become useful in the sense that today, a cooling and freezing equipment of any size can be obtained.
Refrigeration principle has no limitations in application. The most conversant use and one that is common and widely known as the perversion of foods, meanwhile virtually, all products at homes, farm, business, industry, laboratories etc are in some ways affected by refrigeration. In fact, commodities like refrigerator are neither less important nor regardless in the modern society.
