Configure Ventilation at Room Level

Shows step-by-step how to set the ventilation system at the room level.

Before you begin

You would like to configure the ventilation at room level.

Navigate to:

Module overview ➤ Heat load ➤ Room level ➤ Heat load ➤ Ventilation

Procedure

Set the minimum hygienic ventilation heat loss:
- If you would like to use an air exchange rate deviating from the selected standard, enter it next to Air exchange rate.
- If you would like to use an area related air exchange rate, enter it next to Spec. volume flow.
In the first case, the area related volume flow is calculated using the information from the general room data. In the second case the air exchange rate is calculated automatically.
If the air handling system in this room should differ from the globally set one, select an air handling system.
Enter the Air exchange rate or the air flow rates of the ventilation system.
Enter the volume flow Vb and its temperature in the area Supply air volume flow by overflow or infiltration.
Set Further volume flow rates.

Results

The Ventilation for this room is configured.
