ABSTRACT
This work gives an account of all activities carried
out to restore a faulty and abandoned deep freezer to normal functioning. This report therefore contains the different
stages embarked in the execution of the project. These include the literature back ground,
checking’s conducted, cleaning, repair operations and replacement of some
pants.
The project was subsequently assembly
and tested and was found to perform satisfactory and was presented in the last
chapter.

INTRODUCTION
Refrigeration is the process of
removing heat from a space or region and maintaining this at low temperature.
The practical application of this
process is to produce and maintain a temperature below that of the
ambient. For deep freezer, the
temperature is reduces down to the freezing temperature of the refrigerated
substance, thereby freezing the substance in the freezing component.
In the refrigeration process,
there is always a substance employed at the cooling agent, such cooling agent
is known as the refrigerate and it circulates round the condensing and
evaporating region thereby bringing about cooling.
Since people specially those that run
hotels finds it difficult to chill and freeze their drinks and keep their
cooked foods other items in their normal state and the irregularities in this
functioning of some existing deep freezers, we decided to embark on this work.
And with the primary objective
that the project will enhance our knowledge and will expose the group members
on the practical application of their theoretical expositions. And will give us a wilder knowledge on how a
deep freezer works the uses of it. This
will also serve as a means of repairing and putting the damaged parts in proper
shape and better condition for effective use in the homes and shapes and
offices etc.
However, this will benefit the
domestic users in the sense that this
will help them in chilling and preserving of their food and drinks. Hoteliers and restaurants also will find it
useful in preserving their cooked food to the next day.
This
project is limited to repair process or work.
