Dense gas is pumped through small holes within a metal tube, by a motorized "compressor." When this gas makes contact with the metal on the inside, it has a cooling effect and the metal absorbs the heat from the air on the outside of the tube. Once the heat has been absorbed, this air is pumped in, or cycled through the fridge and freezer to keep things cold.

A fan blows away the heat into the room. Then the gas pressure is dropped in the refrig cold room and the temperature drops in the cold room, PV=RT. The heat in the cold room heats up the gas and the volume goes to the compressorr again, ec,etc,etc.
