What does CFM stand for in HVAC?

CFM stands for Cubic Feet per Minute, which is a critical measurement in HVAC systems used to quantify the volumetric flow rate of air. This unit indicates how much air is being moved or circulated through a space every minute, and is essential for designing and analyzing ventilation, heating, and cooling systems effectively. Understanding CFM is crucial for ensuring adequate airflow for comfort and efficiency in indoor environments. It helps determine factors such as the size of ducts required and the capacity of fans and air conditioners, thus enabling proper climate control within a building. Accurate CFM calculations contribute to improved energy efficiency and indoor air quality by ensuring that ventilation systems are neither over nor under-designed.
