ᐅ Arrangement of the supply and exhaust air vents

Hello,

We are currently planning the ventilation system for our new build (ventilated usable area: 215.3 m² (2,318 sq ft), living area 160 m² (1,722 sq ft)). We have received a quote for a Zehnder Q 350. The offer includes 13 supply and exhaust air vents.

In my opinion, 11 supply and exhaust air vents would also be sufficient. I also find the arrangement interesting! On the ground floor, the utility room, laundry room, and kitchen are all adjacent, but only exhaust air vents were planned there.

The attached drawings show the locations of the vents.

What do you think about this proposed arrangement?

Are the supply and exhaust air vents positioned correctly and are there enough of them?

That is correct, since the air from these rooms needs to be extracted. The allocation of supply and exhaust air to the rooms is appropriate.

How many cubic meters per hour (m³/h) are intended to flow through the supply air vent in the living area? I see potential for a second vent here. Otherwise, everything looks consistent (without knowledge of the volume flow rates).

Thank you for the quick response, I forgot to mention a supply air valve in the dining area!

Would it be sufficient to have exhaust air valves only in the utility room and kitchen? And upstairs, in the children's room, both supply and exhaust air valves are planned—is that correct?

The quantity is sufficient; however, I would not reduce it, and I would position the supply air near the windows.
