When buying a refrigerator, it is not so much the size and the external design that are important as the cooling system. Modern household devices can be equipped with a drop system, No Frost , Frost Free or Full no Frost. The two-chamber refrigerator "know frost" has a lot of advantages that you should get to know better.
How does the "know frost" system work?
From refrigerators with droplet thawing, this household device differs in the structure of the evaporator itself. Most often it is placed in a special recess or located on the back wall of the freezer compartment and has the shape of a serpentine with fins. In addition, the cooling system "know frost" is characterized by a special ventilation mode. Under the influence of the built-in fan, warm air gets to the evaporator through special channels, and already in the cooled state enters the freezer. Refrigerators with such a cooling system, as well as household appliances of the old sample, also form frost, but they struggle with it in a special way.
A special electric heater is designed to periodically thaw the evaporator system. Heating elements are switched on every 10-12 hours and provide defrosting of the existing layer of ice and removal of liquid from the freezer compartment. In the event that a fan is mounted on the evaporator, it will act as an air cooler.
