ᐅ Balanced ventilation system in an open-plan kitchen and living area

Hello,
with a controlled ventilation system, fresh air should ideally enter the bedroom and living area. Exhaust air is typically removed through the kitchen and bathroom.
Does anyone have experience with whether the air distribution of a controlled ventilation system is sufficient in an open-plan kitchen adjoining the living area?
Are cooking odors effectively extracted, or is a sufficiently large recirculation range hood necessary?
Does anyone have tips to consider during the planning stage, as we are currently designing a new build?
Thank you very much for any input.

With sufficiently precise planning (air flow plan) and accurate commissioning of the system, this should generally not be a problem, provided the entire process is overseen by a building services engineer.
For an unchecked general contractor/prime contractor project, I would have serious concerns.

Best regards

I don't think a building services engineer can help much with kitchen odors—unless you have such a high air exchange rate that you're practically being sucked in. A recirculating range hood is mainly for controlling grease.

We planned, measured, and adjusted everything. Still, you can smell it in the living room when onions are fried in the kitchen.

When integrated into the exhaust air system, it is possible to select intensive ventilation temporarily and return to normal ventilation after the "disproportionate odor generation" ends. Then, you hardly notice anything at all!

Best regards

@Euro: Unfortunately, that was never really an option for us. We (unfortunately) never thought of doing it, and we have no idea whether the controlled residential ventilation system (Stiebel Eltron LWZ 403) simply can’t handle the grease, or if our home builder just wasn’t interested. He never asked us if we wanted it. The idea would have been good a year ago. Then we could have discussed it with the builder’s HVAC planner.

Is it possible to use a range hood with exhaust air when a central mechanical ventilation system with heat recovery is installed? Of course, only during the time of "disproportionate odor production."
