by the simple fact that expanding air cools down.
in the cooling system, a compressor compresses a fluid, which increases its heat and sends it to the rear of the fridge. These tubes allow the fluid to lose the heat that it gained during compression and return it to room temp. it then enters the fridge and expands into larger tubing the in the main area; expansion of substances results in a drop in temperature. the now-cooled fluid passes over a fan that blows this cold air into the main areas.

One of the simple is the old swamp cooler. The water is pumped over the pads and air is forced through the pads . What makes cool is water that is changed to vapor will absorber 60 calories for each cubic centimeter.The other air conditioners work the same but it is a closed system.

Freon is compressed causing it to be a super cold temperature and the air is circulated through coils that are cooled by the freon creating cold air.

As simple as possible - a gas is compressed to a liquid. This creates heat which is expelled to the outside. Then the liquid travels to the coil where it absorbvs heat as it expands back to a gas. The gas then goes back to the compressor and it all starts over. It is just a cycle. Compressing any gas to a liquid creates heat and anytime a liquid becomes a gas it absorbs heat.

Compress the freon into a liquid, then is passes through a coil to cool the air, so the freon ends up heating up, turning back into a gas, then it goes through the compressor again... repeat.

The air is pumped around a retired politicians heart.

They run freon gas through pipes (which is like -300 F or close to that) and then run the air by those pipes and through a compressor which helps dehumidify then it comes out.

reverse carnots cycle.it takes heat from a colder body and relases it out side.so the colder body becomes more cold.the out side of a refrigerator will be hot.this can only be done mechanicaly.check for carnot cycle and its application for more details

There are 2 ways depending if its electric power or gas power.
