The device of the refrigerator can be viewed from different "angles", given the technical characteristics, various consumer needs and other positions. Now one- and two-chamber models are being produced, with conventional and “crying” evaporators, equipment equipped with the unique No Frost system and the so-called “zero” zones.
Modern designers of household units for cooling are developing a technique that can seamlessly “fit” into the interior of any kitchen or, conversely, attract attention with its bright color or unusual shape.
Nevertheless, the device of the refrigerator, whether it is a standard or an original model, includes almost the same components: a compressor - the engine and the "heart" of any system; an evaporator, which is a plate inside the refrigerator or a shelf in the freezer compartment; condenser - a heating grid at the back of the unit. Cooling occurs due to the circulation of the refrigerant - freon, which is pumped into the system and has a low boiling point. Due to this property, the substance boiling in the evaporator is able to actively absorb heat, thereby cooling the space around it. The standard device of the refrigerator also assumes the presence of a filter dryer, a tube system, a thermal relay (control unit) and a cabinet - the cabinet itself.
In the recent past, single-chamber units in which the freezer was located in the upper part of the cabinet were very common. As a rule, the evaporator in such equipment was the camera body.
The device of the Atlant refrigerator, which has two separate chambers - a refrigerator and a freezer, has an important design feature - the presence in each of the compartments of its own evaporator.
Modern equipment, in which two compressors are installed, independent of each other, allows you to set and adjust the temperature separately in both the refrigerator and freezer compartments. The system also assumes the presence of valves, which in turn block the flow of refrigerant directly to the evaporators of the equipment chambers. In addition, the device of this type of refrigerator includes special sensors and electronic control units.
Manufacturing companies seek to attract the attention of sophisticated consumers to their product in various ways. An important factor when choosing becomes usability.
The “No Frost” system, also known as “Frost Free”, and in Russian, an automatic defrosting system, relieves the owner of the need for a defrosting procedure. Moreover, such a device of the Stinol refrigerator and similar equipment of other well-known brands suggests a more even distribution of the volume of cold air throughout the chamber.
Another plus is the quick recovery of temperature after loading inside a large number of products. Disadvantages, alas, also exist. Firstly, this is an insufficient level of humidity in the chambers themselves, which leads to faster drying of the products. In addition, the usable amount of refrigeration space is “eaten up” by additional built-in equipment. A higher price is another minus. However, in this case, it is fully justified by the complex design and ease of use of such a technique.
