ᐅ Exhaust air and supply air above each other?

Created on: 7 Sep 2016 17:07

Hello,
we are just about to submit our building permit / planning permission application. I still have some concerns about the ventilation system.

My architect says that the exhaust air can be installed low and the supply air above it, with a 2m (6.5 ft) distance between them.
My worry is that the stale air, which is known to rise, might be drawn back in.

Are my concerns justified, or is this not an issue?

Alternatively, the exhaust air could run along the ceiling to the far end of the room. However, that would probably take up shelf space and is less compact.

Routing around the corner is not possible since the room is centrally located.

Thanks in advance for your opinions.

Best regards,
Christopher

I would do it the way you have planned, leaving a 3m (10 feet) distance between the two outlets. I wouldn’t feel comfortable having them directly one above the other, although I don’t have any technical expertise on this—I just wouldn’t have a good feeling about it.

I saw yesterday that one of the neighbors has the outlets positioned vertically above each other. I had never seen that before.

We install the main unit of the mechanical ventilation system in the attic.

At the very top of the gable, an opening is created and a component is installed there. This serves both for supply air and exhaust air.

The exhaust air is expelled directly outward, while the supply air is drawn through a duct angled downward. As mentioned, this is a single integrated component.

I feel the same way.

Supply and exhaust air vents can be positioned one above the other. However, there must be a minimum distance of 2 meters (6.6 feet) between them. Since there are also connection boxes where both are integrated into one unit, this does not cause any problems.
