Prevention of surface condensation
Installations that have a surface temperature that is lower than the ambient air temperature risk forming condensation on their surfaces.
Surface condensation depends not only on the surface temperature of the installation, but also on the relative humidity of the surrounding air.
The higher the relative humidity, the higher the risk of surface condensation.
This calculation module uses the values specified by DS/EN ISO 12241:2008 Table 4 to determine whether it is likely that a ”cold” installation will develop condensation on the surface.
To be able to do this, it is necessary to know both the temperature and humidity of the air surrounding the installation.
By insulating an installation it is possible to reduce the risk of condensation on the surface. However, it is important to point out that the insulation must form an airtight shell around the installation to prevent condensation between the insulation layer and the pipe surface.
