The editor will take you to understand the reasons for the fog in the refrigerated display cabinet

With the improvement of people's living standards, refrigerated display cabinets are more and more widely used, but there is always a lot of water mist on the glass door of the fruit air curtain cabinet in summer, which affects the display effect of the refrigerated display cabinet. Is it normal to have water mist? The refrigerated display cabinet adopts insulating glass in the commercial field, which is composed of two or more glass plates with effective support, evenly separated by distance strips, and glued and sealed around. The heat transfer characteristics of the insulating glass determine the anti-condensation effect of the fruit fresher.


1. With the arrival of summer, the rainfall climate increases, causing the humidity in the air to exceed the normal planning of the supermarket air curtain cabinet, which is the main reason for the water mist problem on the glass door;
2. When the supermarket freezer starts to work, when the temperature inside the box is lower than the temperature outside the box, heat will be transferred, and the heat will be transferred from the outside of the box to the inside of the box through the insulating glass, resulting in a temperature difference, which will cause water mist. When the outdoor temperature is too high, the temperature inside the cabinet can be properly adjusted to reduce the generation of water mist;
3. The support partition is also one of the causes of water mist. Condensation is easy around the glass door, especially the lower edge, because the thermal conductivity of the supporting partitions reduces the thermal resistance around the glass.


When you see many drops of water on the door frame of the refrigerator in the supermarket, don't be serious. this is normal phenomenon. You can properly use the rag to clean up the water droplets.
