What Does a VAV Box k-factor Mean for Efficient Building Operation?
In heating, ventilation and air conditioning (HVAC) systems, airflow reported at the variable air volume (VAV) box is actually a measure of total pressure. It gets converted into an airflow by a multiplier that is generated during testing, adjusting and balancing (TAB). This multiplier is commonly called “k-factor”, but can also be called flow multiplier, […]
