Optimal solution for duct treatment in narrow spaces

Choosing the right ductwork for spaces with limited ceiling height is always a difficult problem for ventilation system designers and installers. Optimizing performance and minimizing air pressure loss are key factors that need to be carefully considered.

In this article, Sao Viet Air Duct will help you learn how to select and handle air ducts to meet the needs of narrow spaces.

Choosing air ducts for narrow spaces:

• Metal ductwork: Although it is the top choice for high efficiency, metal ductwork is not suitable for spaces with limited area due to its bulky size and difficulty in construction.
• Flexible ductwork: The optimal solution for tight spaces thanks to its flexibility and ease of installation. Flexible ductwork can be bent into many different shapes, helping to optimize system layout in limited spaces.

What is flexible duct?

Thanks to its flexibility and easy bending, flexible ducts can be installed in any type of terrain, even in limited spaces. According to standards, the maximum length of flexible ducts should not exceed 4 meters, including the connecting pipe.

Thanks to the glass wool layer, insulated flexible air ducts are often used in high-end projects where insulation and noise protection from the outside environment are required.

Notes when using flexible ducts

Air pressure loss

Due to its special structure, flexible ducts often have higher air pressure loss than steel ducts. Therefore, careful calculation during the design process is extremely important to ensure the overall performance of the ventilation system.

Secure connection

The connection between flexible air ducts and other accessories such as corrugated iron air ducts, air vents, and dampers must be done carefully and tightly to avoid air leakage, affecting operating efficiency and creating conditions for mold growth.

Avoid crushing the tube

During construction and operation, care must be taken to avoid flattening the flexible duct. This may affect the air flow and pressure in the system, leading to reduced ventilation efficiency and increased noise.

Optimal length

The length of the flexible duct should be kept to a minimum to minimize pressure loss. It is recommended that the optimal length of the flexible duct should not exceed 5 meters.

Restricted reverse path

Using flexible ducts that loop back can cause turbulence, which can affect ventilation efficiency. Therefore, it is necessary to design a system with optimized duct paths to ensure smooth airflow.

Using flexible ducts in narrow spaces brings many benefits, but it is important to note some important factors to ensure efficiency and safety during operation. Adhering to the principles mentioned in this article will help you choose and use flexible ducts effectively, contributing to creating a comfortable and safe living and working environment.
