Ductwork Overview
- Ductwork forms the air distribution system in buildings, channeling air from the HVAC system to the conditioned space and back.
- It is integrated into the building's walls, and proper sizing and layout are crucial for efficient air distribution.
- The layout and space to be conditioned determine the required ductwork size.
Industry Standards
- The ACCA Manual D sets the industry standard for sizing ductwork, ensuring proper air distribution for the specific structure.
- A correctly sized HVAC system will not function properly without appropriately sized ductwork.
Considerations for Different Systems
- Not all heating systems require ductwork, such as boiler systems, PTACs, and mini splits.
- These systems may still enhance indoor air quality and adhere to building codes for airflow.
Importance of Proper Airflow
- Proper airflow is essential for oxygen replenishment and removing harmful particles from indoor air.
- Correct sizing and placement of ductwork components (fans, grills, registers, diffusers) ensure adequate airflow within the conditioned space.
