Controlled residential ventilation: positioning of supply and exhaust air in my designs

Can anyone actually confirm here that there is no draft from ceiling supply vents? I've read so often on the internet that the air is cold and that it drafts. What do you do in this case? Do you have to live with it or are there options?

I'm talking about our dining area/dining table. Occasionally, someone will sit at the head sides of the table. Otherwise, the 6 marked seats are used regularly. Will it be uncomfortable at the table?

And is there a draft in the kitchen when standing at the sink?

Absolutely no draft to be felt! Here at my home office workspace, I have the outlet valve directly above the desk. Nothing to be felt! At the floor outlets, I have to get my face very close to feel if air is coming out.

Ok, good to read. I wouldn’t know any other position in the dining room either. It’s somehow always near the dining table/dining area. I had read somewhere that you leave 1m of space to sofas, desks, beds.

I have read on the internet so often that the air is supposed to be cold and drafty.

That is nonsense, unless you connect an air cooler to your controlled residential ventilation instead of heat recovery, as some residents of sauna apartments use in mid-summer—but you won’t do that. The (I don’t know, I’ve never measured it) two-degree difference between air already warmed by your body and the supply air you won’t feel as an “ice wind,” that’s wind force zero point zero eight fifteen. Without a fan just before the outlet vent, the air won’t storm either due to the slight temperature difference. A controlled residential ventilation system does not aim in principle for a sea breeze, but only the same air exchange that you would achieve analogously by opening a window. The “K” in controlled residential ventilation stands for “controlled,” not for “colossal.”

Ok that sounds very reassuring. The topic [Kontrollierte-Wohnraumlüftung] is simply completely new territory for me. Can a planner make a mistake regarding positions? We have moved an air supply vent away from the sofa. Could that be detrimental to the effectiveness of the [Kontrollierte-Wohnraumlüftung]?

You do not have particularly large impacts. It is not really decisive whether a valve is 1m to the left or 1m to the right. Misplanning can occur with the diameters of the pipes.
