Abstract
Fan airflow is the key parameter for air volume
tracking control in variable air volume systems. One
of the airflow measurement methods is to determine
airflow using the fan speed, fan head, and fan curve.
Both fan speed and fan head can be measured
accurately. Therefore, the accuracy of the fan airflow
depends on the accuracy of the fan curve. An
experimental method has been developed to
determine the in-situ fan curve with only one airflow
measurement. This paper presents the theoretical
background, experimental procedures, and
verification results.
