Ambient temperature at which condensation of moisture present in the air is called the dew point.This is not a constant and it depends on the air humidity and the actual ambient temperature.For each temperature there is a limit to the amount of moisture that can be kept in the form of steam.The higher the temperature, the more water can be present in the form of steam.Anything over a given amount is condensed.By reducing the temperature and humidity in a constant amount at some point in the air can no longer be maintained, this moisture is condensed and excess.This temperature is called the d
ew point.

When a medium with a temperature, humidity and dew point temperature of the material falls below the dew point on the surface of its material falls condensation, because a boundary zone cools the surrounding air.

Dewpoint construction

In winter, the temperature outside is significantly lower than in the room.The outer wall surface is cooled, and the interior is heated.Inside the walls of the transition temperature of the material takes a value between foreign and domestic.It is important that the point at which the forming temperature is equal to the value of the dew point of the air inside the room was well away from the inner surface and a uniform thickness of the layer of the wall material.If it is close to the inner surface or inner surface of the dewpoint cooler, then it will condense moisture, which promises a lot of problems.

Excess moisture in a layer of plaster on the surface and can cause damage to the interior trim and the formation of mold and mildew.It is because of the location of the dew point should not insulate the wall from inside the premises.The dew point is displaced closer to the inner surface, as a consequence, condensation and damp inside.

Dewpoint and climate

important components of a comfortable microclimate is air temperature and relative humidity 18-24oS 40-60%.When the relative humidity of 100% the actual temperature is just equal to the dew point.To raise the humidity, different evaporators, humidifiers.To reduce the moisture content can use the air conditioner, in which heat exchanger has a temperature lower than the dew point.As a result, the moisture condenses on the cooler and is removed from the premises.

Dewpoint and anticorrosion coatings

When applying anti-corrosion coating is important that the painted surface has been heated to a temperature above the dew point.Otherwise, the condensation will prevent the tight fit of anti-corrosion coating.
