Air Distribution Systems

The HVAC air distribution system is responsible for transporting the conditioned air from the AHU or TFA Unit to the occupied spaces of a building and also bringing the used air back to the AHU for recirculation. This system typically consists of ductwork, grilles, registers, and diffusers that work together to deliver the Supply Air (SA) that promotes occupant comfort and health. Also, the room air is brought back to the AHU by the Return Air (RA) duct network.

The ductwork is the primary component of the air distribution system and is responsible for transporting conditioned air from the AHU or TFAU to the occupied spaces. The ductwork can be made of materials, including Galvanized Iron, Aluminum, and fibreglass, and is typically insulated to prevent heat loss or gain during air transport.

Air terminals like Grilles, registers, and diffusers are the components that distribute the air from the ductwork to the occupied spaces. Grilles or diffusers are typically located in the return air system and are responsible for pulling air back into the AHU. Lately, Opal HVAC Engineers has also undertaken several projects that used fabric ducts for supply air distribution.

At Opal HVAC Engineers, we ensure the proper design, installation, and maintenance of the air distribution system delivers balanced airflow to all occupied spaces, comfortable air velocity, and noise within the permissible limit.
