BOMA-HVAC Practice Test

Question: 1 / 400

Which of the following terms describes air movement through a duct?

Draft

Airflow

The term "airflow" specifically pertains to the movement of air through ductwork in an HVAC system. It is a crucial aspect of HVAC design and operation, indicating both the volume of air moving through the ducts and the direction of that movement. Understanding airflow is essential for assessing how effectively the HVAC system can deliver conditioned air to different areas within a building, ensuring proper temperature control and air quality.

In contrast, terms like draft refer to unwanted or uncontrolled air movement, often causing discomfort. Static pressure is a measure of the pressure within the duct system and relates to the resistance air encounters as it flows, rather than the flow itself. Ventilation refers to the process of exchanging or replacing air in a space, which can involve airflow but does not directly describe the movement through ducts. Thus, "airflow" is the most precise term when discussing air movement within ducts.
