How do airflow and wind pressure change when the fan is placed at different altitudes?
Fans are affected by atmospheric pressure at different altitudes, and since atmospheric pressure decreases as altitude increases, the volume and pressure of air generated by the fans also change. Generally, as the altitude increases, both the airflow volume and pressure of the fan decrease, but the exact extent of these changes requires specific analysis and calculation based on actual conditions. .
For centrifugal fans, the volumetric flow rate remains constant while the pressure changes; for example, as altitude increases and air density decreases, the fan’s pressure also decreases. There is a linear relationship between pressure and density
