ᐅ Controlled residential ventilation: alternative positioning of supply air vents

Hi everyone,
I have a question regarding the placement of the supply air vents in the ventilation system. In the ground floor and basement, the ventilation ducts are installed in the ceiling. On the upper floor, however, there is no suspended ceiling above the bedrooms due to the pitched roof, resulting in high rooms. The idea was to run the ventilation ducts in an installation plane parallel to the roof to maintain these high ceilings.
What wasn’t taken into account is the ring beam! Now we cannot (or only with difficulty) run the ducts directly beneath the roof into the bedrooms. Lowering the ceiling by half a meter or even fully (parallel to the floor) is not an option for me, as it would ruin the nice high rooms…
Would it be possible to position the supply air vents next to the door or the bed (see plan marked in red)? Although this position is not ideal, since the whole room should be evenly ventilated, the vents blow air into the room. I therefore don’t think the fresh air would be immediately drawn out through the door. Positioning the vent directly over the bed is also not perfect, but since the vent doesn’t blow straight down but rather into the room, it might still work.
To give a clearer idea, below in blue is the originally planned vent position. In red is the new position without the installation plane (two versions: to the right or left of the door).
Thank you for your responses.

So we have the same setup as you want (open rooms, mechanical ventilation outlets not on the floor but in the walls) ... We manage very well with it ... However, someone created a plan for us (either a planner from Zehnder or Erlus, I don’t remember) and in all rooms, the supply air is hidden in one of the interior walls ... based on your picture, I would place it in the interior wall next to the table shown ...

Placing it directly next to the door will cause the fresh air to be immediately drawn out through the door (unless your window is open), so the rest of the room won’t benefit from the incoming air.
