REPAIR AND REHABILITATION OF FAULTY AIR CONDITIONER
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 the 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 has been given in this report; this will benefit those interested in the repairs of the faulty air conditioner in future.

CHAPTER ONE
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 content with the moisture, the relative humidity of the air and its cleanliness.
These air problems can cause a lot of discomforts especially in the places of work, which consequently reduces the working efficiency of an individual.
The problems of air led engineers and scientist to look into methods of bringing comfort to people, which gave birth to the invention of air conditioners. Air condition sucks in air in the room and purifies 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 possible by the use of an air conditioner.
1.2 HISTORY OF REFRIGERATING MACHINE
Air conditioning can about as a result of water-soaked mat that was 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 was 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, the 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 equipment.
1.3 SIGNIFICANCE OF STUDY
This study shows how important an air conditioning unit is at home. The study proffers 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 basis of this study.
