Project Abstract

Abstract
Repair of an air conditioner is essential to ensure optimal performance and longevity of the unit. This research project aims to investigate common issues that arise in air conditioners and explore effective repair techniques. The study will focus on identifying the root causes of malfunctions such as refrigerant leaks, compressor problems, and electrical issues. Various repair methods will be examined, including cleaning, parts replacement, and system recharging. Additionally, the research will explore preventive maintenance strategies to minimize the need for repairs and extend the lifespan of the air conditioner. This includes regular cleaning of filters, coils, and fins, as well as checking for leaks and ensuring proper airflow. The project will also investigate the role of professional maintenance services in preventing major breakdowns and optimizing energy efficiency. Furthermore, the study will evaluate the cost-effectiveness of different repair approaches, considering factors such as the age of the unit, the extent of damage, and the availability of replacement parts. By comparing the benefits and drawbacks of repair versus replacement, the research aims to provide practical recommendations for consumers facing air conditioner issues. The project will involve a combination of literature review, case studies, and hands-on experiments to assess the effectiveness of various repair techniques. Data collection will include monitoring the performance of repaired air conditioners over time to evaluate the long-term impact of the repair process. The research findings will be analyzed to determine the most reliable and cost-efficient repair methods for different types of air conditioner problems. Overall, this research project seeks to contribute valuable insights into the repair of air conditioners, offering guidance to homeowners, technicians, and manufacturers on how to address common issues effectively. By improving the understanding of air conditioner repair techniques and maintenance practices, the study aims to promote energy efficiency, reduce operating costs, and enhance the overall comfort and convenience of indoor environments.

Project Overview

1.1              AIR CONDITIONER

Indoor climate, once adjusted to human need only by opening of heating in winter and by opening windows or using fans. In summer, is now capable of being varied to meet almost any comfort of industrial demand, anywhere on earth with precise automatic control.

With the introduction of air conditioner, the indoor air can be controlled through the blowing and sucking surrounding. Thus because of its comfort to man, need for air conditioning, Engineers, contractors, manufacturers and Technicians rising on a daily basis.

Now, consider for a moment the consequences which would result up all air conditioning systems were to stop. Not only would the temperature and humidity condition become into levable, but industrial production would be adversely affected and activities involving computers, electronics, air craft, precision manufacturing, nuclear power, optics and synthetics, in fact most areas of modern progress would come to a hault.

Today in business, industry, schools, hospitals, hotels, theatres and homes, air conditioner is no longer luxury but an essential part of modern living.

1.2       DEVELOPMENT OF AN AIR CONDITIONING INDUSTRY

            The development of air conditioning industry is an interesting story, illustrating well necessity for close working relationship among scientific, engineering, productions and its beginning with mechanical refrigeration. In the late 1900s. but it was not until 1917, when Nillis, H carrier began to meet the challenges of designing suitable experiment. During the 1930s, the production of air-conditioning began and by firm scientific, engineering and production basis out with a limited market for its products.

1.2              THE AIM AND THE OBJECTIVE OF THIS PROJECT

The aim of choosing this project, is to put in order the damaged air conditioner in proper shape and better condition for effective usage.

To give wide knowledge of an air conditioner, types of operation and uses to the project group (student participating in the project).

Also to show the need to repair than to rep0lace to or to purchase a new system.

It also serves as a reference to other students that are to do a similar project.

1.3              PRINCIPLE OF AIR CONDITIONER AREVERSED CARNOT CYCLE PRINCIPLE (REFRIGERATION CYCLE).

The air conditioner is related to the refrigeration, hence, both use the same principle of the reversed carnot cycle.

It is called the reversed carnot cycle because it operates in the opposite direction. In the carnot cycle, heat is received by the working fluid at a high temperature and rejected at a low temperature. Both processes are isothermal and also two isentropic processes. In this case, a net amount of positive work is done by the working fluid. this is the working of heat engines or heat pump or carnot cycle, positive work is done.

            But cycles can be formed in which the reversed happens. In this case heat is added or received at a low temperature and rejected at a high temperature. By so doing, a net amount of negative work is done on the fluid. this for any refrigeration cycle, the process is made to remove heat from a space or substance to reduce its temperature and transferring that to another space or substance.
