Condensation control
04 October 2015
On air conditioning systems the line temperature is lower than the ambient temperature and so condensation is liable to form. Eventually, this condensation results in damage and maintenance costs resulting from wet ceilings, spoilt goods or disruption to production. Moreover, the insulation effect of a material deteriorates greatly when damp.
In order to prevent condensation, the surface temperature of the insulation must be as high as, or higher than the dew point temperature under defined ambient conditions. There is a relatively straightforward way of calculating the insulation thickness using Armacel's ArmWin Thermal Insulation Thickness Program.
The quality of both the material and the installation has a dramatic effect on performance. In order to help with this the company now offers Armaflex product ranges for download from the NBS National BIM library. BIM objects listed in the library include tube and sheet range products suitable for the leading Revit Building Design software and in IFC format.
