INTRODUCTION 
REFRIGERATION
Refrigeration is a branch of science that deals with the process of removing heat from a substance or space in order to make it cooler.
Refrigerator is defined as a device that is used in cooling the internal temperature below the room temperature (that is between 250C to 300C).
Generally, however, for a space or substance to be cooler, it must loss that heat to another.  Also, for a space or substance to get hotter, it must absorb heat from another, which must be at higher temperature.  For both process to occur, heat must be absorbed or lost, thus heat is the characteristics agent of heating and cooling, consequently, for heat flow there is absorbs at a lower temperature region and rejected at a higher temperature region, that is the quantity being determined by the temperature gradient of the two regions.
The modes of heat transmission are conduction concretion and radiation of which conduct convection and radiation, of which conduction and convection are extensively involved, in domestic refrigeration. 
In refrigeration process, there is always a body employed as the heat absorber or indirect contact with the space or substance being cooled depending on the required final effect. Such cooling agents is known as refrigerant, which is known as the refrigerant, which is circulated around the evaporator that id high temperature region) and condensing region (that is higher temperature) in order to maintain a constant refrigeration process.
It does it work be evaporating (when it absorbs heat up to the boiling point temperature) and by condensing when it losses the absorbed heat to return to its original liquid state, in the system.
These heat when absorbed, may be classified as sensible heat or latent heat depending on the its physical effect on the refrigerants.
