The role of ductwork in HVAC Systems
An effective, high-quality ductwork system is essential to all HVAC systems - especially those featuring high-pressure installations. But what is ductwork and how does it function? Let’s take a closer look at why decent ductwork is such a crucial factor in industrial HVAC systems.
Ductwork meaning
The Collins Dictionary ductwork definition is ‘an arrangement of ducts or pipes for carrying fluid or gas, usually in a building’. This is different to the meaning of ‘duct work’, which describes any maintenance to or work on actual ducts themselves.
What does ductwork do?
In domestic situations, HVAC ductwork is used to transport air around the home for heating and ventilation. In many cases they also serve to improve air quality. Commercial and industrial systems, however, are much larger, more powerful, and more robust. These systems may have multiple applications, such as centralised cleaning, dust extraction, and extraction of hazardous waste.
How does a ductwork system work?
HVAC installations work by using hundreds of ducts to circulate air from one area to another. Each section of ductwork has its own specific purpose, and the size and scope of each system is dependent on the requirements of each building or project.
Let’s explore the fundamental principles of an HVAC system and the role of ductwork using the example of a basic domestic HVAC installation designed to regulate temperature.
A key element is the AHU (Air Handling Unit) which draws in cold air from outside the home or building. This unit uses filters to purify the air, and heating or cooling coils to achieve the desired air temperature. Fans then blow the conditioned air into the ducts. Properly designed ductwork will reach far into every room of the building, where air is pushed through vents in the walls or ceilings at the desired rate of flow to maintain an even temperature throughout.
Ductwork is composed of connecting components including pipes, fans, valves, bends and other elements, many of which can be angled or flexed to gain access to awkward areas. In domestic installations these components are usually crafted from galvanised steel or aluminium.
In industrial environments on the other hand, ducting and ductwork are often made from welded stainless steel. These ductwork systems use the same principles as those in large-scale environments prone to extreme temperature buildup.
