How to prevent condensation on doors and windows.

What is condensation?
The phenomenon of condensation of supersaturated water vapor in the air into water is called condensation. Specifically, the water vapor in the air condenses on the inside of the glass room, and the phenomenon of fogging or water droplets appears, which is definitely not unfamiliar to the car owners.

Why does condensation occur?
When the surface temperature of an object is equal to or lower than the dew point temperature, dew condensation will occur on its surface.
The hot, humid air in the room condenses into water droplets on the interior surfaces of the doors and windows that are colder (to the dew point temperature). When the temperature of the inner surface of the curtain wall of doors and windows is lower than 0 ° C, frost will occur.
What effect does condensation have on life?
Less severe condensation is just a thin layer of water mist on the glass, which greatly reduces the transparency and visibility of the glass and affects the life experience. However, in severe cases, it will drip like a light rain, causing peeling and mold on the wall. It will even frost, causing the door and window frame to deform, destroying the stability and sealing of the door and window.

The following methods can alleviate the phenomenon of glass condensation:
1 Proper opening of windows every day can reduce the humidity of the air and eliminate the moisture generated during the day's activities. Similarly, the dew on the glass can also be air-dried normally.
2 The space where the exhaust fan is installed can be properly turned on to reduce or eliminate the problem of dew condensation.
3 If you feel that the window opening is cold and ventilated, you must often wipe off the dew on the glass with a rag to prevent condensation from forming and causing a water flow to flow to the windowsill and the floor, which will damage the interior decoration.
4 Paste an anti-fog film on the glass. I tried to put an anti-fog film on the glass mirror in the bathroom. I found that the mirror does not have a lot of water mist and it can not be illuminated. Although it costs a little, it may be a try.
5 The more effective methods may increase the cost, such as installing a dehumidifier, a ventilator system, or special performance glass in the home, which can automatically heat the dew-proof glass and vacuum glass.
