Introduction
Insulated flexible ducts are essential components of modern heating, ventilation, and air conditioning (HVAC) systems, as well as other industrial and residential applications. These ducts provide a means to distribute air efficiently while minimizing heat loss, noise, and other inefficiencies. This article outlines the applications, solutions offered by Subo Company, and a numerical analysis of insulated flexible ducts.
Applications of Insulated Flexible Ducts
HVAC Systems
In HVAC systems, insulated flexible ducts play a pivotal role in maintaining energy efficiency and indoor air quality. They are designed to handle different temperature ranges typically between -20°C to 80°C, ensuring that conditioned air is maintained at desired temperatures while minimizing energy loss.
Industrial Applications
Industries use insulated flexible ducts to facilitate controlled air distribution in processes that require temperature regulation. The ducts' diameters can vary from 102 mm to 610 mm to accommodate different flow requirements, ensuring optimal performance in complex industrial settings.
Residential Use
In residential settings, these ducts contribute to energy conservation by preventing heat transfer between the ductwork and unconditioned spaces. Their flexibility allows for easy installation in confined spaces, optimizing the distribution of heated or cooled air within homes.
Subo Company Solutions
Subo Company offers a range of insulated flexible ducts tailored to various industry needs. Their products include:

Numerical Analysis and Parameters
Thermal Conductivity
The thermal conductivity (k-value) of insulated flexible ducts typically ranges from 0.024 to 0.033 W/mK, ensuring minimal energy transfer between the duct and its environment.
Air Flow Velocity
Insulated flexible ducts are designed to accommodate air flow velocities up to 15 m/s, ensuring efficient air distribution without significant pressure loss.
Sound Attenuation
With a sound attenuation capability of up to 30 dB, insulated flexible ducts significantly reduce noise generated by air moving through HVAC systems.
