The glass doors of your walk-in cooler may be making you sweat

  • Those who have visited a convenience store or supermarket may have noticed sweat dripping from the glass doors of walk-in refrigerators as they approached the store or supermarket's front glass door. However, it can occur at any time of the year, and is more common in hot and humid weather (55% or greater relative humidity). Use of properly insulated panels and the maintenance of proper humidity controls are excellent places to begin when it comes to preventing sweat from accumulating on your glass door. Despite the fact that these are the most common reasons for perspiration on your doors, they are not the only reasons.



    What is it that causes the glass to begin to sweat? What exactly is it that is causing it to perspire? So, what exactly is going on in this situation?

    Whenever the surface temperature of an object falls below that of its dew point temperature, condensation will occur on that object's surface. A surface that is above the dew point condenses water vapor on it more quickly than it evaporates because of the difference in temperature between the two states. The dew point temperature is measured in degrees Celsius and is the temperature at which dew forms on the surface of the water. The temperature at which dew point forms rises in direct proportion to the amount of relative humidity present in the atmosphere, as shown in the graph below.


    Generally speaking, condensation occurs most frequently when there is a disparity between the surface temperature outside the cooler or freezer and the temperature within the cooler or freezer. As long as the air is moving, it contributes to the rapid evaporation of water, which prevents condensation from forming on the surface of the water.

    It is because of the poor insulation provided by glass that condensation appears on glass doors on a frequent basis. The presence of condensation in this particular situation is more than a matter of appearances, as will be discussed later. Convenience store refrigerator doors are constantly being opened and closed, which makes them particularly susceptible to condensation problems in the long run. Consequently, they require the use of more humidification controls as a result of their presence.

    Can you tell me what I can do to make sure this doesn't happen again in the future?

    It follows that any obstruction to the free flow of air should be avoided at all costs in order to prevent condensation from forming in the first instance.

    Keep your belongings away from the interior walls of the storage unit to ensure their long-term preservation. A 2-inch gap should be left between the two pieces of furniture in order to allow for air circulation between them. It protects your product because it ensures that your unit is always in peak operating condition, which keeps it from malfunctioning.

    The use of sheetrock or tile on the face of your walk-in closet is also discouraged because this will prevent the air gap from being formed. Rather than using paint grip metal finish on the exterior of the structure, it is preferable to use paint grip metal finish on the interior of the structure. The opportunity to coordinate your appearance with the store's design is provided by this arrangement. As an alternative, a protective wrap can be applied to the metal in order to keep it safe. This allows air to circulate freely in areas where sheetrock and tile would otherwise be obstructed by the materials when they are used in these locations.

    For all of these reasons, if you're looking to purchase a cooler insulated glass hollow glass for your home, you should put your faith in QUISURE to deliver high-quality products. If you collaborate with an experienced team that ensures that the appropriate products are selected and that your project is designed with the environment in mind, the success of your project is virtually guaranteed.
