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

nordanney11 Feb 2015 10:30Personally, I also find holes in the floor unpleasant – that's why we have air vents in the ceilings. However, we only have one window in the entire house that is not floor-to-ceiling – and in front of that, the ventilation openings don’t look very nice either. By the way, a lot of things tend to fall in there, especially with kids 😉 – think Lego Friends or similar.
Bowlstriker11 Feb 2015 10:38What do you mean nonsense? Supply air and exhaust air at the ceiling should obviously not be the case.
Why is the exhaust air in the same room? What kind of planning was that? Or maybe it’s an open-plan kitchen?

nordanney11 Feb 2015 12:02Naturally, supply and exhaust air in the ceiling!
I did not write "in the same room" (but in our case, this is indeed true due to the open kitchen as well as in the sleeping/dressing area).

Thank you for your replies.

A system from Viessmann Vitovent 300w is being installed. However, I believe the system is only purchased from Viessmann.
@Cascada
Regarding the air outlets in the floor, I think they do work. The advantage of this positioning and the windows (as initially planned in our case) is that no floor space is lost.
However, we decided against it because we see the risk that moisture could get into the duct from a knocked-over bottle or a similar accident.
Good luck

Alright then, that’s fine ;-)
The open kitchen is right next to it – true – that’s why there is an exhaust vent. I forgot to mention that.
Of course, supply and exhaust air shouldn’t both be located on the ceiling.
@Fantamoax
With floor-to-ceiling windows, there’s nothing placed in front anyway. Lego and similar toys can’t fall through the small gaps – but you’re right about the drinks, theoretically. Although it’s rather unlikely directly in front of the window ;-)

Doc.Schnaggls11 Feb 2015 14:29Of course, supply and exhaust air vents can each be positioned either in the ceiling or in the walls (just below the ceiling).
Just not in the same room or at least not directly next to each other.
For example, on the ground floor we have supply air in the living room and dining room, and exhaust air in the kitchen and guest bathroom.
On the upper floor, we have supply air in both children’s rooms and the bedroom, and exhaust air in the dressing room and bathroom.
Personally, I’m not a big fan of ventilation outlets in the floor – but that’s more of an aesthetic issue for me.

Dirk
