The Construction Of A Mobile Refrigerator Fridge

The Construction Of A Mobile Refrigerator Fridge

Abstract

This write up focuses attention on a detailed report and account on the process of construction and expression of plan for the factual and physical consummation of the construction of the design work identified fabrication and construction of a mobile cooling system. The report is thus divided into chapters and each chapter bandied considerably similar that an illiterate refrigerator handyperson who read and comprehends the report can fluently accomplish the construction of refrigerator under little guidance and supervision.

latterly, the principles of impacting the operation of a cooling system, choice of accoutrements , colorful styles used in the fabrication and recommendation for advancement were duely treated.

thus, as the cooling system composed of mechanical and electric all corridor, a lot of trouble were made to break and bandy the colorful stages and sequences of assembly. Stating a relatively number of safety rules which must be stuck rigorously to by and intended person or persons, who may embark on the design in future to achieve a positive result.

Eventually, this write up also encompasses the conservation of any cooling system irrespective of the size and make without limiting it to only mobile refrigerator, with due consideration that we’re in the ultramodern age of refrigeration due to the gradational destruction of the ozone subcaste, so that any person who seized the occasion of reading through the report can maintain similar outfit no matter the size and complexity with ease and save himself from being overheated by the sun.

Chapter One

Preface

A mobile refrigerator isn’t a different refrigerator than a refrigerator that’s movable ( ie it can be moved down one place to another with little operation of force).

Then, the mechanical refrigeration has to do with the product of a machine that controls a temperature lower than atmospheric temperature. This implies that it’s t he process of removing heat at a low temperature position and rejecting it at a fairly advanced temperature position.

By its nature, heat flows from a body at a advanced temperature to anot her at a lower temperature but in the rear case, it requires external energy to be fulfilled. T he carrier substance used to carry heat is called a refrigerant. thus refrigerator is the retrograde heat machine cycle.

Refrigeration is fulfilled by colorful styles, similar as the vapour contraction system, immersion system, and brume spurt refrigeration cycle. In this design only vapour contraction system of refrigeration shall be bandied as it was the system espoused to fulfilled the refrigeration.

Refrigeration contributes to the caregiving of living standard of people of all classes and land. Although refrigeration is primarily an of thermodynamics, but advances made refrigerant in recent times to grow into so numerous expression where we need technicians, craft persons, masterminds, scientists, and others from phases of engineering pool chops and knowledge in the design, manufacturer operation and operation of the refrigeration. Complete knowledge of thermodynamics and parcels of refrigerants must be known before the complete cycle analysis can be made.

The operation of the refrigeration principle is measureless. The most common used and bones that’s readily honored is the preservation of food and chilling of our drinks and water during the time we’re feeling hot and need our body to be stupefied.

Purpose Of Construction

The main objects of the this design is to achieve the following purpose viz

To construct and fabricate a movable domestic cooling outfit that would be easy to be moved to any accessible position.

To construct a cooling/ freezing system that’s effective with little or no complexity in conservation.

To construct cooling system that will be mobile, profitable and cost effective that indeed a common man can go.

To produce a machine that will make life easier and more comfortable to live, indeed in a hot terrain, and season.

To construct a movable cooling system outfit with a reduced weight.

Significance And Specification Of Design

The significance attached to this construct is the accomplishment of a fast freezing system without breaking of bottles at veritably low temperature and without adverse goods on the food apkins, the flavour, newness and natural nutrients of food accoutrements . The construction intention is grounded on reduced weight and cost, longer life span, fast freezing ways, conciseness, portability and so on, while constructing this design we put into consideration the Nigeria factor and possibility of expanding and marketability and its adverse goods on our terrain, that’s why we used refrigerant that has no effect on our ozone subcaste.

While taking the specification on the size we put into consideration the item that are to be cooled or saved. Also the press confines and compressor capacity were put into consideration as well.

The essential design parameters for the mobile refrigerator are as follows

Compressor

ii. Capillary tube

iii. Condenser

iv. Evaporator

Thermostat

vi. Refrigerant

vii. Rubber seal

viii. Drier

ix. Relay and load

Breakers

xi. Lagging accoutrements

xii. slicking oil painting

xiii. Mild sword essence distance

xiv. Aluminum distance

xv. stopcock

compass AND LIMITATION

Refrigeration can be divided into three main orders videlicet

Artificial refrigeration

ii. marketable refrigeration

iii. Domestic refrigeration

The design “ mobile Refrigerator ” as it’s name entails is for domestic operation and to some extent for marketable purpose due to its fast freezing nature and mobility.

Well the limitation of this mobile cooling system is principally on its specification in terms of size, capacity and area of need in terms of power source. Grounded on the specification, the outfit isn’t harmonious for artificial use, where large refrigerator unit are more ideal and readily available.

Statement Of Problems

The use of low temperature refrigeration to gain expansion fits has substituted shrunk fitting of essence corridor, in the nipping of aluminum rivets to control age hardening, the stimulation of straphere conditions in the laboratory for the testing of all types of air craft outfit, including the machine themselves requires refrigeration at- 670F, in the process diligence refrigeration is used to carry out similar operation a s the separation of chargers from results.

operation of refrigeration in the medical profession is adding daily, not only in the preservation of certain products, but also in the factual treatment of some physical affections. The use of cold “ anesthesia ” has shown great pledge in the field of surgery. The manufacture of penicillin requires refrigeration and junking of humidity under high vacuum. The same process is needed in the drying of blood tube, and the preservation of blood which requires refrigeration before the sot is fulfilled.

In the refrigerated food assiduity, developments are being so fleetly that it’s delicate to keep abreast of them. In case operation of domestic refrigerators have been supplemented by the entire new field of domestic low – temperature closets for the medication and storehouse of frozen foods, both inc cooked and pre cooked. Lower shops for the storehouse of frozen food are getting common thing both in our pastoral and civic areas. The movement of our foodstuff has been a matter of concern over times, but with the new development in the refrigeration of vessels, rail road, buses and exchanges. These are but a many of the wide operations of refrigeration. In serving some of the function and considering the area and situation of need similar as resort centers, fun and games, academy etc. Hence the need arises further than indeed previous to design of mobile cooling system of respectable standard that will meet certain essential demand similar as portability and cost effectiveness.
