Hello everyone,
Yesterday, we discussed the ventilation plan for the mechanical ventilation system on the construction site. The ducts are planned to be installed in the floor structure on the first floor and then drilled downward. On the first floor, the supply air should ideally be delivered through floor outlets in front of the windows to save usable space. However, we decided to install the outlets about 30cm (12 inches) higher on the wall. Although this means an additional 90-degree bend in the ductwork—which I understand should generally be avoided—the advantage is that no dirt or liquids can enter the opening.
Now to the main question.
In the living room, two air outlets were initially planned. Since we wanted to move one of them (above the coffee table), the suggestion came up to use only one outlet instead. The size will be properly calculated by the HVAC installer.
Are there any advantages or disadvantages to this? I read that the noise level might be higher with a single outlet. However, the general contractor said a larger duct would be installed accordingly.
For now, I am convinced by this explanation. The general contractor noticed that I felt the decision was made a bit too quickly and offered to install two outlets if desired. We are planning to start with one large outlet, and I have until the end of next week to decide.
My wife sees the advantage that a single outlet is less noticeable, and only one hole needs to be drilled through the ceiling.
The living room is approximately 34m2 (366 square feet).
Best regards,
Fanta

Well, I can definitely imagine that air exchange is better ensured if the supply air enters the room high up and is extracted diagonally through the door gap at the bottom of the room. In contrast, if the supply air comes from a floor outlet and is also only extracted again at floor level through the door gap, it might not be able to replace the air in the entire room! Or are there other considerations? Any different advantages or disadvantages?
