The device of a refrigerator and distinctive features of some models

The device of the refrigerator can be viewed from different angles, taking into account technical characteristics, various consumer requests and other positions. Now single- and double-chamber models are produced, with conventional and "crying" evaporators, equipment equipped with a unique No Frost system and so-called "zero" zones.

Modern designers of household units for cooling develop a technique that can seamlessly "fit" into the interior of any kitchen or, conversely, draw attention to itself with its bright color or unusual shape.

And yet the refrigerator device, whether it is a standard or an original model, includes almost identical components: the compressor is the engine and the heart of any system; Evaporator, which is a plate inside the refrigerator compartment or a shelf in the freezer compartment; Condenser - heating grille behind the unit. Cooling is due to the circulation of refrigerant - freon, which is pumped into the system and has a low boiling point. It is thanks to this property that the substance boiling in the evaporator is able to actively absorb heat, thereby cooling the space around itself. The standard device of the refrigerator also assumes the presence of a filter-drier, a pipe 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 popular. As a rule, the evaporator in such equipment was the camera body.

The device of the Atlant refrigerator, which has two separate chambers - refrigerating and freezing, has an important design feature - the presence in each of the compartments of its own evaporator.

Modern equipment, in which two compressors independent of each other, are installed, it is possible to set and regulate the temperature separately in both the refrigerating and freezing compartments. The system also assumes the presence of valves, alternately overlapping the flow of refrigerant directly to the evaporators of the equipment chambers. In addition, a refrigerator of this type includes special sensors and electronic control units.

Firms-manufacturers are trying to attract the attention of sophisticated consumers to their product in various ways. An important factor in choosing is the ease of use.

The system "No Frost", it's "Frost Free", and speaking in Russian - an automatic defrosting system, relieves the owner of the need for a defrosting procedure. In addition, such a device of the refrigerator "Stinol" and similar equipment of other known brands assumes a more even distribution of the volume of cold air throughout the chamber space.

Another advantage is the rapid recovery of temperature after loading into large quantities of products. Alas, there are drawbacks, too. Firstly, there is an insufficient level of humidity in the chambers themselves, which leads to faster drying of the products. In addition, the useful volume of the refrigerator 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 construction and convenience of using such a technique.
