The material-based design of the commonly used fabric air duct, also known as textile ductwork, can prevent condensation. The anti-condensation principle of flexible ducting 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 piping surface, 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 textile ducting can also prevent condensation on the building structure and ceiling. The flexible 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 duct condensation through several aspects:
1. The fabric 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 fabric ducting 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, which means that Durkduct flexible air ducts are the ideal choice for anti-condensation in swimming pools”.
The fabric duct ceiling system 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 piping surface, and the second is to make holes in the surface of the ducting and to throw 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 an anti-condensation effect while blowing out the wind. The permeable textile air duct can permeate the wind through the fiber of the wall of the piping, and can also open the hole on the surface of the air duct. Non-permeable flexible air ducts need to open holes in the piping surface for air supply.

How to choose a profile for different fabric air duct has technical concerns. In general, the air duct can be divided into normal pressure state and negative pressure state. Under normal pressure, the common section shapes are circle, semicircle, 1 / 4 circle, bow, and sector, while under negative pressure, triangle and rectangle are commonly used.
Profile introduction under atmospheric pressure: 1. Circular, if there are not too many requirements for an appearance with space height allows, we suggest to choose this kind of air outlet profile. The air outlet area is larger, and the air output is more, so it is more time to change the indoor air.
2. Semicircle, if the height is not allowed or it can be used in the case of aesthetic requirements.
3. 1 / 4 round, small space, or affected by indoor environment, installation location, and other factors can be used in this way.
4. If the space is too small and the semicircle can’t be installed, you can only choose this smaller bow section.
5. Fan-shaped, irregular installation space, or if you want the duct to be artistic, you can choose this way.
Profile introduction under negative pressure: 1. Triangle, the specific method is to fix the fabric air duct on the top surface and stretch the air duct to the inverted triangle shape by stretching. 2. Rectangle with special support in the middle.
Of course, in the negative pressure state, even if the supporting or stretching effect is better, it will be affected by the negative wind, which will lead to the deformation of the air duct, so this section is generally not recommended. Generally, we will recommend the use of return air duct, which uses high-strength nano alloy materials and unique patented support technology to maintain the perfect rectangular appearance of the flexible air duct, To achieve negative pressure air supply, it can be used in combination with the tuyere and air valve to replace the traditional return air pipe in an all-round way, and it can be installed on-site by steel rope suspension.

What is fabric duct for hvac system? In generally, the hvac fabric duct system is a round or semi-round or other common fabric duct shapes, which is usually made of light-weight fabric duct materials. While in the past, the word “ductwork” often refers to the metal units that moves air throughout the whole facility. The two systems are quite different from each other. Obviously, the new HVAC fabric duct system has much more advantages, which is often made according to customers’ needs of exact duct sock applications.
Fabric Duct Benefits Compared with traditional metal system, the most obvious advantage of fabric ventilation is that the fabric duct material is light-weight. As a result, the ducting hvac system can be packaged in boxes, which are easy to deliver.
When installing the metal system, it often requires additional bracing and securing of all the seal joints. However, the fabric air duct installation is much easier.
Fabric Duct Design Another advantage of fabric ductwork is the design of fabric ducts. Different places require different fabric duct design. According to the requirements of the location of the unit, the height of the space, the aesthetics, and the air supply area in the building and HVAC design drawings, the air duct system is arranged. In principle, the main transmission pipe from the air-conditioning room and the ceiling internal air pipe is designed with the insulation I series insulated air pipes, and some main transmission pipes and branch pipes in the non-ceiling area are designed with N series cables without insulation air duct.
Using our iSox duct design software design software, layout design and drawing operations can be completed more quickly, greatly saving design time and improving design efficiency.
