Diagram 2: Value of the static pressure drop for selected pipes
Table 3: Example of pressure drop calculation
Rectangular elbow horizontal 90°
Flexible tube° (DN125)
Air intake grid
Note:
As mentioned above, the total loss of static pressure, which can be calculated by adding
up the losses of individual elements built into the pipeline system, may not exceed 95 Pa. If
they do, the values of COP start dropping more dramatically.
DETERMINING THE FAN SETTING
When pressure drop is determined, select the mode in which the fan will operate. This
determines the speed of the fan. The mode is selected using Diagram no. 1, which shows
the aerodynamic characteristics of the fan depending on the air flow and pressure drop in
the pipeline*.
Note:
*Pressure drop in the pipeline – in diagram 1 this is marked as pressure difference.
