REPAIR OF A DAMAGED AIR CONDITIONER

REPAIR OF A DAMAGED AIR CONDITIONER

ABSTRACT
This project is basically on the repair of a damaged air conditioner. It is intended to provide a break through in the restoration of any damaged air conditioner and thereby curtail the huge expenses incurred in the replacement of the entire unit.
This report covers an introduction into what an air conditioner is all about, it’s historical background and working principle. A view on the installation techniques and the maintenance application are also contained in this report. The actual repairs undertaken were analysed and the economic cost of the repairs were equally specified.
After the repairs and changing of some damaged components, the system was tested and found to be functional again thereby satisfying the objective of the project.
CHAPTER ONE
1.0 INTRODUCTION
1.1 AIR CONDITIONER

An air conditioner system is an assembly of various components which operate in a controlled manner to produce a specified condition of the air within a space or building.
To produce complete air conditioning, a system must heat, humidify, cool, dehumidify ventilate, filter and circulate air within the conditioned space all for the comfort of the user.
Air conditioner has a wide range of capacities for rooms of various sizes. It has been common to rate units in tons but a better method is by BTU (British Thermal Unit). A small capacity air conditioner may be 5500 BTU and a larger one 15,000 BTU. It can also be rated by horse power, which describes the power needed to drive electric component and not cooling capacity. The capacity required is determined by size of space to be cooled, the building installation, direction of window to sun or shade, heat source in the room (from a gadget0 and the normal occupancy.
The electric voltage required is normally between 115 – 230 volts.
