In a place like a supermarket, if the freezer for storing items has a mist on the surface, all the items that were originally displayed to the customers in the cabinet will be unclear. The customer needs to open the freezer. Over time, the door of the cabinet is easily damaged, and the power consumption of the freezer is increased.
When this happens, we can first take a dry cloth and wipe all the foggy areas. This can basically solve the problem in a short time, because the fog generated on the glass door of the freezer of the supermarket is generally caused by the internal or external heating or uneven cooling. So try your best to keep the temperature inside and outside the same. Of course, this is not the best solution.
In order to avoid such a situation, you can buy an air-cooled freezer. This type of air-cooled freezer can avoid such problems because it can emit air in all directions to make the temperature uniform and avoid the generation of mist. Finally, there is a supermarket freezer that can be heated, that is, there is a layer of heating wire on the glass door to ensure the temperature of the glass door, so that it will not fog up, but such refrigerators generally need to be customized.
