1.4 IMPACT OF LIFE CYCLE
The refrigerator allows the modern family to keep fresh food much longer than before. This along with the modern super market, without a sizeable garden on which to grow vegetable and raise animals, a vastly more varied diet and improved health resulting from improved nutrition. Daily products meats, fish, poultry, and vegetable can be kept refrigerated in the same space within the kitchen (although stuffs for reason of hygiene). (Albert Einsten (2001))
The refrigerator lets people eat more salads fish and vegetable, without having to own a garden or an orchard. Exotic food stuff from far-off countries that have been imported by means of domestic refrigeration freezer allows households to buy food in bulk. It can be eaten at leisure and bulk purchase saves money (see economical of scale). Ice cream, a popular commodity of the 20th century, could previously be obtained by travelling distance to where the product was made fresh and had to be eaten on the spot. Now it is a common food item. Ice on demand not only adds to the enjoyment of cold drinks, but it is useful for first aid and for cold packs that can be kept frozen for picnics, or in case of emergency.
1.5 AIMS AND OBJECTIVES
The project can be used to demonstrate how the various part of a refrigeration system function in addition to what was taught during lecture. The project also works as an act to a step forward in educating the student about refrigeration, most especially those who are interest in the technology of refrigeration.
Also, storing and preservation of food can be achieved with the use of the project.

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 o ...

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 commerc ... 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 co ...

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 (e ... 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 typ ...
