The material-based design of the commonly used sox air duct, also known as cloth air duct, can prevent condensation. The anti-condensation principle of the sox air duct is mainly to use the permeability of the fiber of the pipe wall to form a cold air layer on the surface of the pipe wall, so that there is basically no temperature difference between the inside and outside of the pipe wall, thereby preventing condensation. (The greater the permeability of the material, the smaller the temperature difference between the surface and the interior of the material, and the less likely it is to condense.) At the same time, the hydrophobic treatment of the fiber material surface of the processing duct further improves the surface anti-condensation effect. At the same time, the sox air duct can also prevent condensation on the building structure and ceiling. The sox air duct only needs to be added with jet holes to form a "protective layer" of airflow on the building surface, and it can prevent condensation through several aspects:
1. The cloth air duct has flexible openings, which can send air toward the condensation prevention surface, promote surface evaporation through a certain wind speed, and prevent condensation water.
2. Form a lower temperature area near the ceiling height to prevent water vapor from floating.
3. When the humid air passes through the unit, the air humidity of the jet from the sox air duct to the surface of the anti-condensation structure has been greatly reduced, so the air moisture content near the surface area is low, and it is not easy to condense on the structure surface. With the advantages of anti-condensation, combined with its aesthetics in swimming pools, it has to be said that "sox air ducts are the first choice for anti-condensation in swimming pools".
The air sox fabric duct is discharged under static pressure, and the material is divided into permeable type and non-permeable type. The first is to penetrate the wind through the fiber of the whole pipe wall, and the second is to make holes in the surface of the wind pipe and to blow out the wind through the spray holes. It is usually a linear and uniform opening air supply. The combination of the two methods also provides anti-condensation effect while blowing out the wind. The permeable cloth sox air duct can permeate the wind through the fiber of the wall of the pipe, and can also open the hole on the surface of the air duct. Non-permeable sox air ducts need to open holes in the pipe wall for air supply.
