The refrigerator device can be viewed from different "angles", taking into account technical characteristics, various consumer requests and other positions. Now one- and two-chamber models are being produced, with conventional and "weeping" evaporators, equipment equipped with a unique No Frost system and the so-called "zero" zones.
Modern designers of household cooling units are developing appliances that can seamlessly "fit" into the interior of any kitchen or, conversely, attract attention with its bright color or unusual shape.
And yet the device of the refrigerator, whether it is a standard or original model, includes almost the same 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; the condenser is a heated grate at the back of the unit. Cooling is due torefrigerant circulation - 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 it. The standard device of the refrigerator also assumes the presence of a filter-drier, a pipe system, a thermal relay (control unit) and a housing - the cabinet itself.
In the recent past, single-chamber units were widely used, in which the freezer was located at the top of the cabinet. As a rule, the evaporator in such equipment was the chamber body.
The device of the Atlant refrigerator, which has two separate chambers - a refrigerator and a freezer, has an important design feature - the presence of its own evaporator in each of the compartments.
Modern equipment, in which two compressors are installed, independent of each other, allows you to set and regulate the temperature separately in both the refrigerator and freezer compartments. The system also assumes the presence of valves that alternately block the flow of refrigerant directly into the evaporators of the equipment chambers. In addition, this type of refrigerator device includes special sensors and electronic control units.
Manufacturers seek to attract the attention of sophisticated consumers to their product in various ways. Ease of use becomes an important factor when choosing.
The "No Frost" system, it“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 "Stinol" refrigerator and similar equipment of other well-known brands implies a more uniform distribution of the volume of cold air throughout the entire space of the chambers.
Another plus is the rapid temperature recovery after loading a large amount of food inside. Unfortunately, there are also disadvantages. Firstly, this 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 refrigeration space is “eaten up” by additional built-in equipment. The higher price is another downside. However, in this case, it is fully justified by the complex design and ease of use of such a technique.
