No-frost or defrost?

Nofrost is derived from the English word NOFROST and means no frost. In nofrost or nofrost refrigerators, no frost is visible inside the refrigerator. But this does not mean that there is no frost. In this model of nofrost refrigerators, the cooling radiators or evaporator coils are covered with a cover so that they are not visible. In this way, cool air is directed into the cabin by a fan and is designed so that the frost resulting from moisture, by the command of the electrical board or timer when the element is turned on, the frost melts and is directed through a path to a chamber on the compressor and there it evaporates by the heat of the compressor (refrigerator motor), which also helps to cool the compressor, and you do not see any frost in this system. This system is called nofrost.
