ABSRACT - [ Total Page(s): 1 ]ABSTRACTRefrigeration is term used to denote the maintenance of a body at a temperature lower than that of its surroundings. The applications of refrigeration are many and varied. In addition to the common applications of refrigerationin the manufacture of ice, in the preservation of foods, in air-conditioning filed, and in the creation of skating rinks, the refrigeration effect is also used in the presentation of blood plasma, in the low-temperature treatment of metals and in the liquefaction of gasses. Each application requires a different temperature for the refrigerated space. This project

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1 HISTORY OF REFRIGERATIONBefore the invention of mechanical and thermal refrigeration system, ice houses were used to provide cool storage for most of the year placed near fresh water lakes or packed with snow and ice during the winter, they were once very common (Pauken mike 1999). Natural means are still used to cool, also mountain sides run-off from melting snow is a convenient way to cool drinks, and during the winter, one can keep milk fresh much longer just by keeping it out doors.In the 11¬¬¬¬th century, the Persian physicist and chemist 1bn S ...

CHAPTER TWO - [ Total Page(s): 2 ]CHAPTER TWOLITERATURE REVIEW2.1 ABSORPTION SYSTEM OF REFRIGERATION The absorption system is difficult from the compression system. It used heat energy directly instead of mechanical system. It uses heat energy directly instead of mechanical to make change in the deduction necessary to complete as refrigeration cycle. The system may use element as source of heat (Paunken Mike, (1999) ). The system has fewer moving parts and operates relatively quietly. Such systems are used in commercial installations as well domestic installation. In recent years they are used in recreated vehicles ... Continue Reading
CHAPTER THREE - [ Total Page(s): 3 ] CHAPTER THREEANALYSIS OF REFRIGERATION SYSTEM AND CHOICE OF PROJECT AS BEST.3.0 THE CYCLE OPERATION OF VAPOR COMPRESSION. The cycle operation of vapor compression is as follow:- The liquid refrigerant (e.g R12) enter the evaporator- As liquid refrigerant and absorbs heat in the evaporator, the vapor is drawn through the suction line to the compressor.- From the compression, the refrigerant is compressed at supper heated temperature and high pressure to the condenser- All the condenser the refrigerant is considered at high pressure and heat is disputed ...

CHAPTER FOUR - [ Total Page(s): 3 ]CHAPTER FOUR4.2 ASSEMBLY AND INSTALLATION The first stage of the assembly is the laggings materials and its facing the aluminum sheet.4.2.1 LAGGING MATERIAL AND FACING ALUMINUM SHEET The polystyrene is cut to thickness of 25mm. this is used to cover the internal of the cabinet. Then, the laying of evaporators through the polystyrene, one end of the evaporator is welded to the compressor to serve as inlet. The chemical sheet is used to face the polystyrene with the use of gum (evostic) and rivet pin. ... Continue Reading
CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVERECOMMENDATION AND CONCLUSION5.1 RECOMMENDATION- The use of electric voltage regulator (stablizer0 recommended when using the freezer. - It is also recommended that the freezer should be used for domestic purposes.- Preventive maintenance should be carried out as at when due.- The project is unable to modification.- The project is a very good size, it improves students knowledge of thermodynamic engineering therefore it is recommended that this type of project should be continuous.5.2 CONCLUSIONRefrigerator is one of the applications of the ...
