Built-in refrigerators with No Frost function

No Frost system

— this refers to refrigerators that have No Frost technology only in one of their compartments, typically in the freezer compartment.

No Frost function in refrigerators prevents frost formation on compartment walls by removing excess moisture from the air. This is done by driving air with a fan through a special compartment, where the moisture condenses, flows into a tray, and then evaporates due to the heat from the compressor. This eliminates the need to defrost the refrigerator regularly to clear the ice.

No Frost is convenient because it prevents frost formation on the compartment walls and eliminates the need for regular defrosting. However, it can cause unpackaged food to dry out faster due to faster moisture evaporation. This is less of an issue for freezers, but protection from moisture is still important.
