A refrigerator is a device that is found in every modern home. To keep the refrigerator working, you need to follow simple rules. One of the most important rules is not to put anything hot in the refrigerator.
The most ordinary refrigerator has a typical operation scheme. All devices of this type use the same principle and the logic of their operation has not changed for many years. Whether it's a home refrigerator or a workshop refrigerator.
From an early age, children are taught not to put hot things in the refrigerator. To understand why this cannot be done, you need to understand the device of a modern refrigerator. The mechanism of operation is simple and interesting.
The device of a modern refrigerator
Any classic refrigerator is a sealed chamber with a door. The walls are equipped with good thermal insulation. The use of thermal insulation is very high and, accordingly, the chamber must be sealed. The door is fitted with an elastic band. The rubber in the refrigerator door is special. It has the ability to be magnetized to the metal body and maintain a tight connection between the door and body. The magnetization is provided by the presence of magnetic dust in the rubber compound. The use of such rubber bands allows you to make the door lightweight and not to make special latches.
A fully closed door ensures that the chamber is tight and thermally insulated. In addition to the body and the door, the refrigerator consists of a compressor and a coil. A coil is a tube that contains a special substance.
The design uses not one coil, but several at once. One is located on the back wall outside the refrigerator, and the other is located inside the refrigerator compartment. The inner coil is hidden in the walls of the chamber behind a beautiful plastic lining.
… This to some extent clarifies the logic of the refrigerator.
How the refrigerator works
The trick that is used in the operation of the refrigerator lies precisely in the temperature difference between the internal and external coils. This difference is achieved due to the different state of aggregation of the liquid. Here you need to focus on what. This liquid is called refrigerant or freon.
Remembering the laws of physics from the school curriculum, you can pay attention to the patterns in the boiling process. During the boiling process, energy is absorbed. This means that an ordinary vessel in which there is a boiling liquid will be cooled, since energy is required to boil the liquid.
It is important to understand that this process cannot be compared with boiling a kettle, the walls of which are hot. In this case, the kettle itself heats the water. In the case described above, the liquid boils spontaneously. This is due to the difference in pressure. The lower the pressure in the space where the liquid is, the lower its boiling point. Surely you know that
Now think about home refrigerators. It is located inside the walls of the refrigerator. When freon boils, the coil cools down to about -18 degrees, which provides cold inside the refrigerating chamber. This cold can be used to keep the temperature inside the chamber low.
In parallel with this process, the steam from freon is compressed by the refrigerator compressor, turning back into liquid. Then it enters the coil located outside the refrigerator, where it cools down. The coil is equipped with a radiator for efficient cooling. During the operation of the refrigerator.
Now the main question remains related to the reason for the transformation of freon into steam and its boiling inside the walls of the refrigerator. Here, too, everything is very simple. After all, this is what determines the use of special refrigerants. After all, not every liquid is capable of boiling with small decreases in pressure. The mechanism of work is logical and understandable.
Why you can't put hot stuff in the refrigerator
Understanding the logic of the refrigerator, you can answer the question why you shouldn't put hot things in the refrigerator.
The condition for the operability of the refrigerator is the process of boiling freon inside the walls. The wall cools down, and temperature sensors inform the compressor that the freon circulation process can be temporarily stopped and the refrigerant can be stopped boiling. This is of particular value when discussing the energy saving of the device.
Accordingly,. The refrigerator will start and run without stopping until the hot one cools down. It. In addition, the process of functioning of the refrigerator is questionable. After all. When a hot object enters the refrigerator chamber, the state of freon changes.
All the factors described can lead to the failure of the refrigerator. The compressor will overload, and if the workmanship is poor, it will break. This kind of indifference can easily ruin even a new modern refrigerator.
There is also one who has put a hot product in the refrigerator. If you put hot food inside the refrigerator, then the glass shelves can crack from a sharp temperature drop, and the walls of the refrigerator will be intensively covered with frost, which will turn into a whole ice cap. Such an ice cap will reduce work efficiency.
