A continuous passageway for air transmission that includes various components is referred to as what?

The correct answer is a duct system, which is characterized by its role as a continuous passageway specifically designed for the transmission of air. Duct systems are integral in HVAC (Heating, Ventilation, and Air Conditioning) applications, where they facilitate the movement of conditioned air throughout a building. They typically include various components such as ducts, fittings, grilles, and diffusers, all of which work together to distribute air effectively and efficiently.

This term is distinct from alternatives such as vent systems, which are more focused on the exit points for air rather than the entire passageway, and airway or channel system, which may not necessarily pertain to HVAC terminology specifically. Understanding the anatomy and function of a duct system is crucial for anyone working in the mechanical field, as it helps in ensuring proper air flow, efficiency, and comfort in designed spaces.
