ABSTRACT
The
need for an authentic and reliable report relating to the repairs and
rehabilitation of a faulty air conditioner is inevitable. The fact that many people use the air
conditioner to cool the temperature in their respective home and offices make
its maintenance a top priority to every individual in order to avoid huge
expenditure in the repairs of the system.
This report
gives insight into the relevance of an air conditioner, the history, the
working principle and the general maintenance one is expected to carry out for
effective performance of the air conditioner.
It also includes the report on the faults discovered with the repair
work carried out in the project.
Subsequently,
advanced information pertaining to the repairs involving a faulty air conditioner
have been given in this report; this will beneficial to those interested in the
repairs of the faulty air conditioner in future.

1.1 INTRODUCTION
All most
all the countries in the tropical are faced with one problem of air or the
other. Ranging from not being contented
with the moisture, the relative humidity of the air and its cleanliness.
These air
problems can cause a lot of discomfort especially in the places of work, which
consequently reduces the working efficiency of an individual.
Thee
problems of air led the engineers and scientist to look into methods of
bringing comfort to people, which gave birth to the invention of air
condition. Air condition suck in air in
the room and purify it, and then heat and cool and supply them back to the room
by the process of heating, cooling, humidifying, dehumidifying, filtering,
cleaning, distribution through the help of a blower in the air condition.
It has been
in operation for a long time but most users prefer new modern air conditioner
due to the modern technology introduced in it.
Today pure air purification can be made possibly by the use of air
conditioner.
1.2 HISTORY
OF REFRIGERATING MACHINE
Air
conditioning can about as a result of water soaked mat that were hung across
window and doors to produce cooling system by evaporation during hot dry
weather.
WILLIAM THOMPSOM, who later became LORD KELVIN, contributed immensely to
the development of refrigeration, some of his other works included the absolute
temperature scale, the law of conservation of energy etc. However, it w as WILLIS CARRIER who conducted the research which when published in
1911, gave the foundation on which to days air conditioner was built.
In the
early stage of its invention, air conditioner was a hazard because of the
explosive or poisonous nature of the refrigerants in use then. It was in 1928 that suitable refrigerants
were discovered and used for more effective air conditioning. This led to a high increase in demand and
expansion in air conditioning equipments.
1.3 SIGNIFICANCE OF STUDY
This
study show how important an air conditioning unit is at home. The study proffer a concise guide to relevant
steps of maintenance, what to do in order to discover a fault in the air
conditioner and how to remedy the situation.
1.4 LIMITATION OF STUDY
We
are expected to explore all avenues and ways to find the sample and proper
procedure in repairing the air condition given to us as our study, without any
exception or delineated areas left out.
Basic maintenance of all types should be the bases of this study.
