ᐅ Is a centralized exhaust-based controlled ventilation system common in the kitchen area?

Hello to the collective intelligence,

We are currently planning a central mechanical ventilation system with heat recovery. The open-plan area has an L-shape. The kitchen exhaust is recirculated air, and we do not have a chimney. In the open-plan area, supply air vents are planned in three corners.

Now my question: In the first planning version from the general contractor, there is no exhaust air vent for the mechanical ventilation system in the kitchen area or anywhere else in the open-plan space. I thought exhaust air vents were standard according to recognized technical guidelines in wet rooms and kitchens? Before I follow up on this, I would like to ask for your opinions.

Thank you,
Jürgen

Yes, the exhaust air belongs in the kitchen.

Thank you very much. I will have that incorporated then.

45 m³/h (27.5 cfm) is the required airflow rate for bathroom and kitchen ventilation.

Out of curiosity: which regulation is this referring to exactly?

My building technology also doesn’t include exhaust ventilation in the kitchen, but there is one in the adjacent WC...

Hello,

Is this covered in the DIN 1946-6 residential ventilation standard?
