The basic knowledge of the ventilation fans
7/19/2012 7:35:18 PMA.The amount of wind.The air volume is referring to ventilation fans in
the discharge (or supply) of the amount of air per unit of time,in
accordance with standards: air flow also known as flow.The air volume
of the ventilation fans is the rated voltage and frequency to the
maximum speed gear operation, the method by air performance test, when
the static pressure is zero, The volume of air volume of the impeller
transmission per unit of time.Unit: m3 / h (cubic meters per hour) or
m³ / min (cubic meters per minute).
B.Power.To assess the ventilator energy power measurement ventilator motor input power. Ventilation fans motor input power is measured at the same time measure the amount of wind.Unit: W (watts)
C.Pressure.The pressure difference in air pressure caused by the ventilator's inlet and outlet at both ends. Ventilator pressure at rated voltage, rated frequency under normal operation, the test method according to air performance, air flow is zero when the pressure, unit: Pa (Pa).
