Question: 1 / 400

What does the term "duct sizing" refer to in HVAC?

The measurement of duct insulation

The calculation of duct dimensions for air distribution

Duct sizing refers specifically to the calculation of duct dimensions necessary for efficient air distribution within an HVAC system. This process ensures that the system can deliver the appropriate volume of air to each area while maintaining proper pressure and minimizing energy losses. Correctly sized ducts help in achieving optimal airflow, enhancing comfort levels, and improving energy efficiency by preventing overwork of the HVAC equipment.

While duct insulation, installation, and material selection are important aspects of HVAC system design and functionality, they do not define duct sizing. Instead, duct sizing is solely focused on determining the right measurements and configurations needed to move air effectively through the ducts. Proper duct sizing contributes significantly to the overall performance and efficiency of the HVAC system.
