It is called refrigerant, major refrigerant is hydro fluoro carbon (HFCs).
Heat exchange pipes in a refrigerator are responsible for transferring heat from the inside of the refrigerator to the outside environment, allowing the refrigerator to maintain a cool temperature inside. The pipes contain a refrigerant that absorbs heat as it evaporates inside the refrigerator and releases it as it condenses outside. This process helps in cooling the interior of the refrigerator.
Ammonia gas is compressed until it becomes very hot from the increased pressure. This heated gas flows through the coils behind the refrigerator, which allow excess heat to be released into the surrounding air.
The thin copper fins on the cooling pipes of a fridge help to dissipate heat more efficiently. The larger surface area created by the fins allows for better heat transfer from the refrigerant inside the pipes to the surrounding air, helping to cool down the fridge more effectively.
The energy to warm up the pipes behind the fridge typically comes from the compressor in the refrigerator, which circulates a refrigerant through the coils. As the refrigerant moves through the coils, it absorbs heat from inside the fridge, releasing it behind the fridge and warming up the pipes.
I'm not entirely sure, but I think the way a fridge works is that they have some special kind of liquid which needs to be really hot to evaporate, and they have special pipes that turn it into gas, so it draws all the heat away from the food, and that's why the back is hot.

Simply, because that is where the warmest air is, inside a refrigerator. Air rises as it's heated, as heated air is less dense than cold air.

It goes through the pipes
The color of glycol pipe lines can vary, but they are commonly painted blue or green to help distinguish them from other types of pipes. These colors can also indicate that the pipes contain a cooling agent like glycol.
When you plug in your fridge, the electricity energises the freon in the copper piping, which then spreads all over the fridge cooling it down. The biggest pipes are at the top, which pushes cold air to the bottom. Doing so, the warm air is in turn pushed up and when it gets to the top, it is cooled by the pipes. The process is then repeated over and over and over. This is how the food is cooled in a fridge xxx

refrigerator
AnswerPumping nitrogen through refrigerant piping during brazing is an excellent practice. The reason is that nitrogen helps to prevent the buildup of oxide scale on the inside of the pipes during the brazing process. Refrigerant is a natural cleaning agent, and as it is being pumped through the pipes it will pick up the scale and contaminate the refrigerant. It is possible that this will damage to the compressor.
