Hi!

For the central controlled residential ventilation, I have found the following important points to consider so far:
- Extractor fan only with recirculation
- Doors with gap at the bottom
- Wood stove with room air-independent supply air

A few points that are still unclear to me:
- Clothes dryer in the utility room. There are some with recirculation and some with exhaust air to the outside.
Which one do I have to choose?
Do I also have to ventilate this room? (Supply or exhaust?)

- Bypass
what is the difference compared to a controlled residential ventilation without bypass?

- Shock ventilation function:
Shock ventilation can be done via switch or automatically.
What exactly happens there?

- and finally:
what are the additional costs for bypass and shock ventilation function in the purchase price?

Maybe someone can explain this to me.

best regards

Yep. A controlled residential ventilation system can only work if the building envelope is airtight. If you pump out 100m³/h with an exhaust hood, you will create a negative pressure in the house. This means either turning off the controlled residential ventilation when the hood is running and tilting the window or using recirculation. Turning off the controlled residential ventilation can possibly be done with a window sensor and a sensor on the hood.

But with controlled residential ventilation, you only need the hood as a grease filter anyway. Odors and humidity are then removed by the controlled residential ventilation itself.
