CHAPTER ONE
1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
Refrigeration is a process of cooling or removing heat to lower the temperature of a space, or items to be stored in the space, to a temperature below the temperature of the surrounding area. This is accomplished by using a mechanical refrigeration process in which a refrigerant is used to alternately absorb heat from the space or object to be cooled and reject the heat to atmosphere or ship.
A cold room is a chamber that is built expressly to prevent heat from passing from outside to the produce inside. It is not possible to construct a chamber that will not allow some heat to pass through the walls, floor and ceiling, and this heat which is constantly leaking through into the chamber has to be removed, just as that of the produce itself is, and transported to the sea or the atmosphere. The quantity of heat that leaks through depends upon the difference of temperature between the inside and outside of the cold room, upon the construction of the walls, floor and roof, and upon the extent of the surfaces exposed to the action of the heat.
Cold room for ship work, and for a good many other places, are built up as follows: The space to be occupied by the cold chamber is surrounded by a double wall, which should extend to the decks, both above and below, both walls being formed of wood. Where it can be arranged; and where it is strong enough to stand the strains that are brought against the walls, they are built of matched boarding, securely nailed to uprights, the two sets of uprights being braced together and lined on the insides (the sides facing each other), and covered with waterproof paper. There are several papers made, consisting of tough manilla or other substances, saturated with substances impervious to water and to the rays of the sun, and these are used to line the space in which the insulating material is to be placed. Between the two walls, it will be understood, there is a space, broken up to a certain extent by the supports of the walls themselves, and into this space the insulating substance is poured and tightly packed.
Cold room in ships is very important for the transported goods as well as for the crew. The onboard air conditioning provides the crew with a comfortable climate for carrying out their daily tasks. Simultaneously, the machinery and cargo onboard ships need to be provided with fresh and cool air as well.
1.2 PROBLEM STATEMENT
Challenges in onboard ship are inevitable as long as ship is man-made. Marine Engineers face many problems onboard a ship. The cold room can also get into some trouble from time to time. Some of these problems are common but require immediate attention. This work was carried out to discuss how cold room challenge of an onboard ship can be overcome.
1.3 AIM AND OBJECTIVES OF THE STUDY
The main aim of this work is on overcoming the challenges of cold room maintenance onboard a ship. The objectives are:
- To analyze the possible challenges of onboard ship cold room
- To discuss how cold room of an onboard ship challenges can be overcome
- To study the operation of the room of an onboard ship.
1.4 SCOPE OF THE STUDY
The scope of this study covers stating different problems that hinders old room maintenance, troubleshooting and stating their maintenance techniques.
1.6 SIGNIFICANCE OF THE STUDY
This study will serve as a means of exposing marine engineers to different faults or challenges of cold room of an onboard ship.
It will also serve as a means of exposing the student involve on the operation and importance of a cold room of an onboard ship.
