25. Air renewal
In order to ensure sufficient ventilation in a room, production hall, warehouse or room, we should calculate the air volume to be extracted. According the activity type inside the room, the air renewal rate might be very variable.
The flow to ensure is calculated taking into account the volume of the room multiplied by the adequate renewal rate.
Q (flow in m³/h) = room volume (m³) x renewal rate / hour
Here is a table with some of the indicative values for recommended air renewal rate.
