Definition

Noun: A passage or channel, typically made of metal or other rigid material, designed to convey air from one location to another as part of a ventilation, heating, or air conditioning system.

Usage

An "air duct" is a specific component of an HVAC (Heating, Ventilation, and Air Conditioning) system. It is used to transport air, which can be fresh, heated, cooled, or exhaust air, throughout a building, vehicle, or enclosed space like a mine. The term is most commonly used in technical, construction, and engineering contexts.

Examples

• The maintenance crew cleaned the dust from the building's air ducts to improve indoor air quality.
• Cold air was blowing weakly from the vent because the air duct was partially blocked.
• In the spacecraft design, each air duct is critical for maintaining a breathable atmosphere.

Advanced Usage

• "to duct air": While "air duct" is a noun, the related verb phrase "to duct air" means to channel or convey air through a duct system.
  • The new system is designed to duct air more efficiently from the rooftop unit to all floors.
