Refrigerator maintenance common sense
2022-02-16
Some people think that the more frost inside the freezer, the better the cooling effect of the freezer, and the better if it freezes. This view is not correct.
The amount of frost inside the freezer is related to the humidity in the box. For example, putting food with high water content in the box or opening the door too many times can cause excessive frost on the inner wall of the freezer and frost on the inner wall of the freezer. It is not that the more the better, the less the better, because the heat transfer coefficient of frost is low. If the thickness of the frost layer exceeds 10mm, the cooling effect will be significantly reduced. Therefore, as a refrigerator, the thickness of the frost layer on the inner wall will be found. When it exceeds 10mm, it should be defrosted.
Determine whether the cooling effect of a freezer is normal. Since it is mainly to check the temperature in the refrigerator box, if the temperature in the box meets the requirements of the instructions, the refrigerator is normal.
Because the manufacturing process of the refrigerator requires that there are no evaporating tubes in some parts, the parts here may not be frosted, and because the temperature in the refrigerator is gradually transferred to each position, the refrigerator will reach a balanced state after a period of operation. The temperature of the refrigerator is not much different, so the amount of local frosting or frosting cannot be used as a criterion for judging the refrigeration effect of the refrigerator. At the same time, it is also very important for the user to master the correct use of the refrigerator.

For example, do not put too much cold food in the box. There should be a gap between cold food and cold food to facilitate the circulation of air-conditioning. The refrigerator should be placed in a place with good ventilation and no direct sunlight. Only correct use can ensure the normal operation of the refrigerator.
