What does the acronym CFM stand for in HVAC calculations?

The acronym CFM stands for Cubic Feet per Minute, which is a critical unit of measurement used in HVAC calculations. This value represents the volume of air that is moved or circulated each minute and is essential for determining the airflow within heating, ventilation, and air conditioning systems.

Understanding CFM is crucial for HVAC professionals as it helps in sizing ducts, selecting fans, and ensuring that systems operate efficiently to maintain the desired indoor air quality and comfort levels. In essence, measuring airflow in CFM allows HVAC technicians to design systems that are capable of delivering the necessary ventilation and climate control needed for various environments, ensuring optimal performance and energy efficiency.
