ABSTRACT

In all types of air-conditioning work a through knowledge of the b basic principle is very important. The report is divided into four chapters which cover the practical application of air-conditioner in different field. The type of operation carryout in the repair include the following. Wash of the film, replace of the compressor with a new one, replacing of the metering device with new one, servicing of the condenser. The manufacturing process of work carry out is cutting of the pan, bending and folding, riveting.

INTRODUCTION

Repair and rehabilitation of air condition has come into existence since after the discovery of an air conditioner which broken down after a period of one. In the previous days, the selective humility of air was very low in most part of the world, this lead to uncomfortable atmospheric condition to individuals.

There was need for Engineers and scientist to make research and came to the solution of this problem. They produced an appliance to bring cooling to the temperature known as an air-conditioner. After a period of time, it developed a fault and was about to be dumped.

Before a new one can be purchased, there was need to repair and rehabilitate the faculty one to an acceptable standard for use again.

Therefore the repaid and rehabilitation of a faulty air-conditioner in approach taken to restore the functionability of the air-conditioner and make it able to air-condition the environment and brings human comfort.
