Many friends in the north have encountered the problem of frosting doors and windows, today, let's learn how to solve the problem of frosting of doors and windows!
First, what is the frosting of doors and windows
Frost is the condensation of dew or fog on the inner surface of doors and windows When the surface temperature of solids (glass, window sash, window frame) is lower than the dew point temperature of the surrounding moist air, the water vapor in the air becomes liquid water, condenses on the cold solid surface, resulting in frost phenomenon When the frost is severe or cannot evaporate quickly, the water droplets will form and flow along the edge of the glass The doors and windows of the yang side have less frost, and the kitchen and bathroom on the shady side have more frost.
Second, how to deal with the frost of doors and windows
1, proper window ventilation every day, can reduce the air humidity, discharge the moisture generated by the day's activities of the glass knot dew can also be dried normally.
2, can be properly opened with the space of the exhaust fan, reduce or eliminate condensation.
3, if you feel that the window is very cold, you should often wipe off the dew on the glass with a rag to prevent condensate from forming a water flow, flowing to the window sill and the ground, damaging the interior decoration.
4, the glass is pasted with an anti-fog film, although the cost has increased a little, you can also try.
5, more obvious methods may increase costs, such as installing dehumidifiers, ventilation systems or special performance of glass at home, can automatically heat dew-proof glass, vacuum glass and so on.
Even energy-saving windows with the least condensation potential depend on indoor relative humidity When the relative humidity is greater than 40%, the outdoor temperature is -20 °C or less, and the better performing high-performance glass will frost.
According to the survey, the main reason for the frosting of doors and windows is that the indoor humidity is too large, the water demand per square meter during the construction of the house is 40 kg, if the house is not completely dry before, after check-in, the bathroom and the shower room, then a large amount of water evaporation takes a long time to cook food, plant a large number of flowers and grass and other activities to aggravate the indoor humidity; at a certain temperature, the indoor humidity exceeds the saturated water content in the air, and the moisture in the air will condense and settle on the objects at a lower temperature, resulting in condensation Even if the doors and windows are insulation sufficient, Frost may occur if the humidity in the room is too high.

6, it is recommended to make warm edge gaskets Because the cost of warm edge gaskets is higher than that of aluminum gaskets, most domestic projects will choose low-cost aluminum gaskets when selecting materials, and the use of warm edge gaskets will reduce the occurrence of frost.
