Details of Ventilation Results

Information about the Results tab in the ventilation output window at room level.

You are here:

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

Volume flow rates

List of all air volume flows involved in the air exchange of the room.

Ventilation heat loss

Calculated heat losses due to existing air volume flows.

Load percentages of the systems

Indicates by which part the ventilation heat loss is reduced by heat input from the air heater. The value of Ventilation losses to be covered by radiators/panel heating is automatically taken into account in the design heat load.
