Isolated drywall chamber for controlled residential ventilation in the attic

You simply lead outside air and exhaust air in and out over the roof.

That means she should lead the exhaust air (also from the kitchen) up there, and on the other hand also use it to support the frost protection of the little room?

Exhaust air is what comes from the controlled residential ventilation after the heat exchanger.

The elephant memory is really unbelievably good! Respect! We finally insulated the entire attic... Supply air and exhaust air in the little room I mean like ventilating a room. So that the temperature is kept reasonably high.

Exhaust air is what comes out of the controlled residential ventilation system after the heat exchanger.

The original poster asked, using this term, but also specifically regarding the exhaust air from the cooker hood, from which I then developed my follow-up question: whether routing it up there would still bring enough waste heat to help the small room.

Yes, the controlled residential ventilation system is planned with heat recovery.

And no, don’t misunderstand. The exhaust hood from the kitchen on the ground floor is supposed to go directly out through the kitchen exterior wall by the shortest route. Of course, it should not go up into the attic. My question is only: if I cook downstairs and blow the kitchen air out of the house through the exhaust hood, whether the distance from the ground floor to the attic is enough if I bring the outside air into the attic above the exhaust vent hood. Whether the kitchen odors practically mix enough with the outside air so that I don’t suck the kitchen smells back in through the controlled residential ventilation system.

In the attic, it would be better to go through the gable wall side than through the roof itself, right? Through the attic exterior wall should be considerably cheaper than through the roof itself. The controlled residential ventilation system requires an outside air connection and also an exhaust air connection to the outside. And both simply through the wall of the gable side of the attic.

The terminology regarding controlled residential ventilation should be clarified.

Exhaust air is what is blown out of the house. Extract air is what comes from the rooms into the controlled residential ventilation.

The extract air of a cooker hood actually has nothing to do with this as it forms a separate system. As far as I can read from the explanations, an automatic shutdown of the controlled residential ventilation should therefore be provided when the cooker hood is running.

when I draw the outside air in above the exhaust air hood in the attic.

That is technically not possible. You cannot draw anything in through the outlet.

That makes more sense:

when I draw the fresh air in above the outside air hood in the attic.

But wouldn’t it be better to go through the gable wall side in the attic rather than through the roof itself?

Basically makes no difference. The main thing is that you have a distance of 2m or you use the Vallox hoods which are designed in such a way that exhaust and outside air can be placed next to each other in the wall without mixing.
