Measuring Airflow and Static pressure of cooling fans

2016-05-25  Hits:82

An AMCA Standard 210 double chamber is used to accurately measure volume and static pressure.

The Maximum static pressure and maximum air volume of cooling fans measurements must be taken separately.

Maximum static pressure measurement :when the nozzle is closed ,the pressure in chamber a will reach a maximum . The pressure difference ps represent the maximum static pressure achievable by the fan.

Maximum air volume measurement : the nozzle is closed,the pressure in chamber a to ps-=0. The maximum air volume can then be calculated using pn,D and the air volume equation above Q represents the maximum achievable airflow with the fan in free air.
