Refrigerators work on the principle that when a fluid is under reduced pressure, it's temperature drops; if the fluid is a gas, this is indicated by the gas law PV=RT, where P=pressure, V=volume, T = temp, R=gas constant. If the volume is constant, and the pressure drops, T drops. In a refrigerator, the fluid is first compressed; this raises its temperature. The fluid is sent through cooling apparatus (radiator) which removes the heat into the surrounding atmosphere, dropping the temperature back to near room temp. In the refrigerator box, the pressure is released from the fluid, and its temp drops below room temp, drawing heat from the box interior. Refrigeration merely transfers heat from inside the box to outside.

It is "Freon" gas which socks the heat from the refrigrators...
The circulation of this gas is the basic principle applied working for the refrigrator...
From the inside it takes off the heat..and this heat is exhausted out in the outer envoirnment...and the gas is compressed again to the cycle to continue...

By absorbing heat at lower temperature at high pressure in liquid form to vapor by Joul-Thomson expansion effect, loosing heat to atmosphere after compression (increase in temperature.

REFRIGERATORS WHEN WE ON POWER THEN IT PRODUCES COOLING EFFECT INSIDE AND THEN REMOVES HEAT IN THE FORM OF CHLORO FLUORO CARBONS.SO COLD ENVIRONMENT INSIDE DOESNOT GO OUTSIDE AND WILL BE TRAPPED KEEP OUR FOODS FRESH FOR SO MANY DAYS.
