The refrigerator is an indispensable household appliance for storing and preparing food in the kitchen. There are different types of refrigerators, there are many functions of refrigerators and there are different internal accessories with which they can be equipped. In this article, we will find out the operation and construction details of a refrigerator.

The refrigerator is one of the most well-known and used kitchen appliances, an indispensable element in a modern household. This is why buying a refrigerator is so important.

Born out of the need to preserve food, the refrigerator has evolved so much over the years that it has become, in most cases, a high-tech product with increasingly practical functions, obviously combined with an elegant aesthetic and adaptable to every taste. There are cheap or more expensive refrigerators on the market, depending on your budget.

The refrigerator is used to store food in a cool place with temperatures of about 4 degrees Celsius. In some cases, "food for the refrigerator" can only be stored for a few days, in other cases, it can be stored for a few weeks, depending on the expiration date. In other cases, food can be stored for a long time at lower temperatures in a special compartment called a freezer. In the last two cases, the refrigerator becomes an indispensable cold storage room.

The refrigerator consists of three parts:

  • engine - which determines its operation;
  • the space where food is stored;
  • the doors that close the compartment.

In turn, the engine consists of a compressor, external grille with the condenser, thermostatic valve, evaporator, and internal grille.

The internal compartment consists of:

  • thermostat, which regulates the desired temperature;
  • compartment lighting;

shelves and containers for food, which can be of different sizes and shapes, depending on the special product for which they are intended.

The refrigerator works with a compression system, in which the refrigerant is compressed. Initially, the refrigerant is sent to the external network, which has the task of increasing the pressure to make it liquid.

The condenser of the external network cools the liquid and extracts its heat, then through the thermostatic valve, the liquid enters the evaporator, where it expands again due to the existing pressure difference and the liquid becomes gas again, which absorbs the heat of food inside the compartment.

Finally, the gas returns to the compressor, from where the described cycle begins again. This operation is repeated until the inside of the refrigerator reaches the desired and set temperature. At that moment a thermostat will stop the action of the compressor.

All new generation refrigerators are equipped with an antifreeze system. It is a cooling technology used in both refrigerators and freezers. In the No Frost system, the air is forced to circulate inside the refrigerator through a system of pipes.

In this way, the cold air circulates throughout the refrigerator, constantly and uniformly. This prevents frost from forming on the inside walls of the refrigerator.

In the long run, frost, in addition to hindering the operation of the coil, leads to the formation of large amounts of ice in the compartment, which prevents the normal cooling of food and takes up a lot of space, so much so that in the case of older refrigerators, periodic manual defrosting of the compartment is required.

The benefits of these No Frost refrigerators are not limited to defrosting. This technology allows you to have more space available for food, to get a fast cooling and, therefore, to reduce energy consumption.

The latest generation refrigerators offer multiple possibilities in terms of functions and practicality, thanks to the latest technologies. For example, many types of refrigerator-freezers have thermal sensors and digital displays.

Also, when an LCD screen is not available, the internal temperature control of both the refrigerator and the freezer can be performed electronically. In addition, the sensor, which is very sensitive to thermal variations, can automatically adjust the ideal temperature for food, depending on the temperature outside the refrigerator and, therefore, the season.

The design of refrigerators, especially the latest generation models, can satisfy any type of taste and can be adapted to any style of furniture. From stainless steel to the brightest colors, such as yellow, red, or blue, from the most original models to the classic white or cream, the refrigerator can look similar to the rest of the kitchen or can stand out. In addition, you can choose a built-in refrigerator for extra elegance in the kitchen.
