A prerequisite for fresh air to enter through the fresh air valve is that air can leave the house. A rule of thumb is that there should be a fresh air vent in every bedroom and living room. In the kitchen, the air goes out through the kitchen fan and in the bathroom, the air goes out with the help of a bathroom fan. Air into the bedrooms. Air out in the kitchen and bathroom.
Another thing that is important for fresh air vents to work is that the air can flow freely between all the rooms.
A final tip is that the bathroom fan should run constantly, not just at elevated humidity levels.
Location fresh air valve / supply air valve
The number of fresh air valves is controlled by how many rooms there are in the house and the size of the rooms. The rule of thumb is a fresh air vent in every room except the kitchen and bathroom. If the room is larger than 25 square meters, two fresh air valves should be installed.
The fresh air valve location on the wall should be made a bit above a window. Slanted to the side.
