A duct is a conduit or pipe used to transport fluids (such as water, air, gases, oil, etc.) from one place to another. Ducts can come in many different sizes and shapes, and are used in a wide variety of applications, from ventilation and air conditioning systems in buildings, to oil and gas pipelines that transport fossil fuels over long distances.

Pipelines are also used in industrial processes to transport materials and chemicals, and in civil engineering for water and sanitation management. The ducts can be made of materials such as steel, plastic, concrete, ceramic, among others.

What does a duct do in an air conditioning system?

In an air conditioning system, ducts are used to transport conditioned air from the central unit to different rooms or spaces in a building. The conditioned air is cooled or heated and then distributed through the ducts to the different supply points, such as diffusers or grilles, that are located in the walls, ceilings or floors of the rooms.

Proper duct design and installation are essential to ensure that the HVAC system operates efficiently and effectively. Ductwork must be well insulated to prevent energy loss and to maintain a constant temperature of the conditioned air as it moves through the system.

The ducts must also be correctly sized so that the air flow is sufficient for each room or space and to avoid excessive noise. In addition, ductwork must be regularly cleaned and maintained to ensure good indoor air quality and to prevent the accumulation of dust, dirt, and other contaminants.
