If an extra static pressure is required on the return air duct, the freecooling should add a return fan section.
This return fan section includes a discharge damper.
The operation dampers for this freecooling with return fan is as follow:
As much as the air intake damper opens, that much the by-pass damper closes and the discharge air damper
opens, for the air return suction (see drawing).
This means that at the same time is reached a free cooled of the room, the discharge or return air and the air of
the room gets removable.
