Refrigerators have one main goal, to keep whatever is placed inside cold. And all refrigerators keep items cold by using one ingenious method. Basically, to create the cold atmosphere of a refrigerator the refrigerator absorbs heat and discards it. For this method to work, the fridge relies on a set of coils. The aluminum coil inside of the refrigerator is known as the evaporator and the copper coil, underneath the metal casing and along the sides of the refrigerator, is known as the condenser. Both of these sets of coils hold the same purpose, to transfer the heat out of the refrigerator. This allows the cold air to constantly stay put on the inside of the refrigerator.

As the condenser absorbs the hot air the cold air needs to be preserved. Every crack of the refrigerator contains insulation to constantly contain the cold air and expel the heat. The insulation also defends from the heat that is produced by the fridge itself. The evaporator coil can be found in-between the freezer and the refrigerator. This coil is filled with refrigerant, which is a mixture of hydrofluorocarbons. These hydrofluorocarbons have the ability to easily absorb and release heat. Basically the idea of a refrigerator hinges on how quickly these hydrofluorocarbons absorb and release heat. The evaporator is also strategically placed. As I have stated earlier the evaporator is placed in-between the fridge and the freezer. This is usually quite high up inside of the fridge. This is because the heat rises and is absorbed by the evaporator which allows cold air to be released. The condenser coil that is wrapped around the sides of the refrigerator expels the heat and disperses it into the air around the refrigerator.
