High altitude on the blower flow, pressure impact?
The air volume according to the design requirements of the wind pressure according to the design value and then by the density ratio of the standard value of the pressure value of the selected example of the design value of working conditions 80 degrees C air volume 10000m3 / h wind pressure 2000pa 80 degrees C ...
It is only to pay attention to the factory test because the manufacturer is close to the sea level density high operating conditions motor power will have overload hazard fan use in different gas temperature selection when considering the temperature on the density of the wind pressure on the motor power gas density With the temperature is inversely proportional to the working density = standard density ((273 +20) / (273 + working temperature)) fan selection
So the selection of the air to 10000m3 / h wind pressure 2000 * (1.2 / 0.68) = 3529pa selection according to this specification selected fan model speed installed at 3000m height when the wind pressure is 10000m3 / h 2000pa As for the motor power selection To calculate the power of the sample without the sample
The wind pressure according to the design value and then calculated by the density ratio of the pressure value of the standard selection example design value conditions 3000m altitude altitude air volume 10000m3 / h wind pressure 2000pa because the sample is standard
The use of wind turbines in high altitude areas to consider the choice of altitude on the impact of the density on the wind pressure to the following table to find the different altitude of the gas density m 1000 2000 3000 4000 5000 density kg / m3 0.98 0.93 0.88 0.78 0.7 fan Selection of air flow according to design requirements
