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

The best solution for positioning is:
The room must have proper airflow... either supply or exhaust air should be placed as far away from the door as possible... or if both supply and exhaust are in the same room, they should be positioned as far apart as possible and ideally not on the same wall or ceiling. Depending on the size of the room, this rule can of course be adapted...
Speaking of floor vents... even if there is some spillage, it is usually not a problem...
By the way, the number of vents is negligible as long as the system has been properly calculated...

hm.?
What is actually the best recommended solution?
Supply and exhaust air (each separately in the different rooms) at the ceiling or in the floor?
Regards and thanks in advance, scooter.Opinions probably differ here – there are various solutions ;-)
If the system is properly designed, it probably does not matter.
In our case, the exhaust vents are always located up high (ceiling or wall), and the supply air comes from the floor in front of the full-height windows.
Aesthetically, it doesn’t really make a difference. The exhaust grilles are white and round, while the supply air grilles are rectangular and made of visually very appealing stainless steel.
How can you achieve the best airflow—without drafts—if we put aside the appearance for a moment?
Should the supply air come through wall or ceiling vents in the upper supply rooms, and the exhaust air be drawn out through the gap under the door—using the kitchen exhaust on the ground floor and the bathroom exhaust on the upper floor through ceiling or wall exhaust vents?
Or, with the same exhaust system, should the supply air come through floor outlets?
