ᐅ Place the fresh air supply of a mechanical ventilation system in the bedroom wall

Hello,

I have now received the first draft of the ventilation layout plan from the professional. He designed on-floor flat ducts (so far, I haven’t found any solid disadvantages compared to in-floor round ducts).

In the basement and ground floor, air supply and exhaust outlets are planned in the ceiling, which is not a problem.

In the attic, however, he does not want to do this because the ducts would have to run through the uninsulated/ unheated attic, which could cause condensation inside the duct system—this would not be good.

Therefore, the supply and exhaust outlets will be installed in the walls. Exhaust air at 2.20 m (7 ft 3 in) height, supply air at 0.5 m (1 ft 8 in) height.

These are planned, as shown in the attachment, nicely positioned in the corner, which I think would create an optimal airflow path.

However, beds are often placed in corners. Having a bed in front of the supply air outlet sounds rather impractical. Firstly, because the opening would be blocked by the bed, and secondly, because it would cause a draft while lying in bed.

Wardrobes will go along the long free walls. The two windows in the cross gable are floor-to-ceiling, the others are half-height windows. I understand that under the half-height windows a desk is often placed, allowing a good view outside. The latter is definitely a debatable point, but I don’t want to discuss it at length.

In my opinion, the exhaust air outlet at 2.20 m (7 ft 3 in) height can stay in the bed corner since I sleep low and wouldn’t notice it.

The issue mainly concerns the two children’s rooms. Here I was thinking that the supply air outlets could either be placed right next to each of the floor-to-ceiling windows or in the wall between the two children’s rooms.

What are your ideas and concerns about this?
Do you see the condensation (dew point) issue differently? I still believe that having supply and exhaust outlets in the ceiling would be the nicest solution.

Thank you very much.

As mentioned, the two windows in the dormer are floor-to-ceiling.

I don’t understand the problem.
Here in our model home development, they are always installed before the floor-to-ceiling windows.

The desks? What do they look like, and isn’t it such a waste of floor-to-ceiling windows meant to let in natural light? No, I wouldn’t want that.

The air vents!

Then I still don’t understand what you mean by "in front," do you mean in the ground or something else?

Yes, floor vents, because that is the simplest option, basically the counterpart to the vents on the ground floor. And since, as you have also noticed, nothing is placed in front of a floor-to-ceiling window, the airflow there is also not obstructed.
