Ventilation and air conditioning

Controlled ventilation system according to DIN 1946-6

The calculation module for controlled ventilation system was newly designed for version 8. The calculation of the flow rates are in accordance with DIN 1946-6, for which the general requirements for the "nominal ventilation" is determined. We describe the module exemplifying the process.

Adjust and optimize air flow

After you have defined the properties of the usage unit in tab Lüftung you compute the balance of air flow.

In the upper part of the dialog you see all the parameters that determine the outdoor air flow rate according to DIN 1946-6. The table lists all rooms in the usage unit. You have the following options:

According to DIN 1946-6, the outside air flow for a usage unit is determined by comparing three values, based on the following criteria:

  • Number of persons, multiplied by the volume flow per person (1). (Setting in tab Lüftung)
  • Area of the usage unit, calculation according to table 5 (nominal ventilation) (2)
  • Sum of the room values, calculation according to 7 (nominal ventilation) (3)
