You feel hot when you are near refrigerator ?Check out why ?

 Refrigeration, came into effect to tackle  more pressing problem that is food spoilage.Of course, for generations people had kept their foods chilled using an insulated box containing a hunk of ice.The refrigerators  in all homes today combine this simple icebox with the same technology used in air conditioning. A refrigerant fluid is made to vaporize via change in pressure, absorbing heat from inside the fridge, and then condense to a liquid state releasing heat into kitchen,

Both the fridge and air conditioner use pressure differences to promote vapourization and condensation.
