Modern models of refrigerators are equipped with the "Know Frost" system. In translation this name means "no frost". The system allows landlades not to think about the need for a monthly defrosting unit.
The principle of the refrigerator "No Frost"
The refrigerator equipped with the Noë Frost system operates according to the following principle. Its characteristic feature is the presence of a built-in fan-cooler. The purpose of the fan is to ensure a constant circulation in the refrigerator of cold air. Between the two compartments - refrigerating and freezing, there is a special compartment, which contains the evaporator.
The air enters the evaporator on one side, where it is cooled, after which the air exits on the other side, leaving the frost on the evaporator. During the non-working time of the compressor the frost thaws. Above the compressor, on the back of the appliance, is a tray, into which water flows.
For the "No Frost" system, it is peculiar that it is equipped with both freezers and refrigerated cabinets.
The best refrigerators with the Noë Frost system are represented by such brands as Atlant, Bosh, LG, Vestfrost, Sumsung, BEKO, Siemens, Mitsubishi.
Pros and cons of the Noë Frost system
The undoubted advantages of such units include the following:
- rapid cooling of products, as well as the minimum difference between temperatures throughout the entire volume of the refrigerating chamber. This is achieved by the constant forced air circulation;
- faster freezing of products compared to other refrigerators;
- rapid recovery of temperature after frequent opening and closing of the door.
But with all this, the Noë Frost system has its drawbacks:
- smaller capacity compared to conventional refrigerators due to the fact that the "No Frost" unit occupies the entire internal volume of the unit;
- because of the fan operation, more electricity is consumed;
- When the refrigerator is working, a greater noise level is formed;
- probability of airing products. Therefore, they must be packed;
- in comparison with conventional refrigerators have a higher cost.
