Some people wonder why the freezer glass door does not frost, because the temperature inside the freezer is very high, and there is usually a temperature difference between the normal temperature outside the freezer and the temperature inside the freezer. According to knowledge, there should be frost in the refrigerator. But not only there is no glass door of the freezer, but the glass on the glass door is also very clean and not easily polluted by dust. This is because the freezer is equipped with special defrosting equipment.
The glass doors used are also specially treated to prevent frost.
So-called defrost devices have heating coils on the surface of the refrigerator that emit a certain amount of heat at regular intervals to dissolve the frost on the surface. Moreover, this kind of heat is strictly set, and its ability can only melt some frost, and it will not affect the internal storage of the product, that is, even in the heating stage, the product stored in the refrigerator can maintain a constant temperature.
In addition, temperature sensors are installed in the glass freezer. When people set the temperature of the refrigerator, once the system finds that the temperature is about to exceed the set temperature, it will start cooling, and the temperature will not exceed the set temperature, so as to achieve the purpose of constant temperature. In this way, items can be preserved better and items will not be affected by temperature.
