Fabrication of Domestic Deep Freezer

ABSTRACT

Refrigeration 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 adopts the basic principle of refrigeration to construct a portable deep freezer The historical development of refrigeration system was discussed along with types of refrigeration system, its impact in our life, how it works and so on. Materials for each component were carefully selected. troubleshooting was included in this report to guide the user on repair and maintenance procedures the total the length of the deep freezer is 99 0mm while the base of the bottom is 750mm, the cabinet cover is 1200mm and his side is 750mm. the special feature are aluminum, thermostat, evaporator pipe, drier cooling fan, polystyrene and TL danfos compressor while the cooling temperature is 125°f
