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

Hello,

could you please review our plans regarding the supply and exhaust air locations?

I’m quite overwhelmed. Visually, the vents don’t look good at all, but they have to go somewhere. What is the most elegant way to solve this?

Do you think this layout is good?

At first glance, the supply air position in the living room (ground floor open plan, left side) stands out. The sofa will be placed directly underneath it...

Also, on the upper floor, there are three supply air vents on the floor. I find that rather unattractive and I’m concerned it might be inconvenient for cleaning.

Is it possible to simply change these floor vents on the upper floor to ceiling vents, or would that involve significant additional costs?

I would appreciate your feedback.

Thank you in advance!

Can anyone here confirm whether there is any draft coming from ceiling air supply vents? I’ve read many times online that the air is supposed to be cold and that drafts occur.

What do you do in this case? Do you just have to accept it, or are there solutions?

I’m asking about our dining area/dining table. Occasionally, someone will sit at the ends of the table, otherwise the six regular seats shown. 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 exhaust vent directly above the desk. Nothing noticeable at all!

With the floor vents, I have to get my face really close to tell if any air is coming out.

Ok, easy to read. I honestly wouldn’t know any other place for it in the dining room either. It’s always somehow near the dining table/dining area. I read somewhere that you should leave about 1 meter (3.3 feet) of space from sofas, desks, and beds.

That’s nonsense, unless you connect an air cooler instead of the heat recovery unit to your mechanical ventilation with heat recovery system, as some residents of sauna apartments do in midsummer – but I assume you won’t do that. The (I don’t know exactly, I’ve never measured it) two-degree difference between the air already warmed by your body and the supply air won’t feel like an "ice wind"; it’s wind speed zero point zero eighty-five or something like that. Without a fan right at the outlet vent, the air won’t gust because of the small temperature difference either. A mechanical ventilation with heat recovery is designed to provide controlled ventilation, not a sea breeze; it simply achieves the same air exchange you would get by opening a window for ventilation. The "M" in mechanical ventilation with heat recovery stands for "mechanical" (controlled), not for "massive."

Ok, that sounds very reassuring. The topic of controlled ventilation is completely new to me. Can a designer make mistakes regarding the placement? We moved an air supply vent away from the sofa. Could that negatively affect the effectiveness of the controlled ventilation system?

You won’t have any significant impact. It doesn’t really matter whether a valve is 1 meter (3 feet) to the left or 1 meter (3 feet) to the right. Incorrect planning can occur with the diameters of the pipes.
