ilmanvaihtokierroksia
Ilmanvaihtokierroksia refers to the number of times the air in a building is completely replaced with fresh air within a specific time period, usually an hour. This metric is a key indicator of a ventilation system's effectiveness in maintaining indoor air quality. A higher number of ilmanvaihtokierroksia generally means more fresh air is being supplied, which helps to dilute indoor pollutants such as carbon dioxide, volatile organic compounds, and moisture.
The required rate of air changes per hour varies depending on the building's use and occupancy. For
Factors influencing ilmanvaihtokierroksia include the design of the ventilation system, such as the capacity of fans
