Protection against condense
The prevention of condensation on
cold surfaces is another application of the adsorption
dehumidifier. Free water on the surface of materials
will often result in a quick depreciation: Paper/carton
will crease, iron will corrode within a short time,
etc.
Such a formation of condensation will
take place when humid air meets a cold surface: The
air around the cold surface will cool down and the water
will be condensed. It is a question of the dew point
of the atmosphere (or the dew point temperature) being
higher than the temperature of the cold surface.
In practice, condensation is found
in e.g. waterworks, where the cold pipes are "sweating"
during the summertime, the dew point of the air being
high and the pipes being cold – or in breweries
where the water content of the air is condensing on
the surface of the tanks. In Ice rinks you will find
the same problem, in as much as the ice will cool down
the rest of the building, which is why during the summertime
you have a risk of the air condensing on walls etc.,
resulting in damage from humidity.
In all the above mentioned cased the
solution is to lower the dew point of the air to at value
inferior to the temperature of the coldest surface.
In this way you avoid a condensation of the air. The
only possibility of lowering the dew point is by means
of dehumidification, there are no other alternatives.
As it is often a question of cold rooms and lower dew point,
the adsorption dehumidifier will usually be the correct
choice.
At the same time the installation
of adsorption dehumidifiers is an economically good
solution. As an example waterworks buildings are often
proof, which is why small-sized dehumidifiers with a
low energy consumption may be installed.
HBC adsorption dehumidifiers are used
as condensation protection for i.a.:
• Containers
• Bridges
• Windmill towers
• Waterworks
• Breweries
