Non Permeable system
Non Permeable System
A non-permeable duct is made from DFC-0 material, which has zero permeability. All supplied air is therefore delivered into the room only through openings in the outlet. These openings can take various forms, such as DFC perforation or plastic nozzles.
Since a non-permeable material is used here, there may be situations where the air inside the outlet becomes much cooler than on its surface, resulting in condensation forming on the outlet’s surface.
These systems are designed to maximize the air velocity through the distribution elements. Cooling with these systems is therefore efficient, albeit at the expense of environmental comfort.
During cooling, it is also necessary to ensure that the temperature of the supplied air is above the dew point to prevent condensation.
