In HVAC systems, what does the acronym CFM stand for?

CFM stands for Cubic Feet per Minute, which is a critical unit of measurement in HVAC systems. This acronym represents the volume of air being moved or delivered by a system within a specific time frame—one minute, in this case. CFM is essential for assessing the efficiency and performance of heating, ventilation, and air conditioning systems.

Understanding CFM helps HVAC professionals determine airflow requirements for spaces, ensuring adequate ventilation and comfort levels. It also plays a vital role in system design, enabling calculations related to duct sizing, equipment selection, and maintaining proper indoor air quality.

While the other options might seem plausible at first glance, they do not accurately reflect the relevant terminology used in the HVAC industry. By focusing on the precise definition of CFM, we can better comprehend its significance in air movement and system efficiency.
