About Room Types
Explains the concept of room types in the domestic ventilation concept.
Depending on the selected room type, a room is classified as a supply air room, extract air room or overflow air room according to DIN 1946-6 for the calculation of domestic ventilation. In the ventilation-related room data, you can subsequently adjust the room type according to DIN 1946-6. This is where rooms can also be defined as non-ventilated rooms. Unheated rooms have to be switched off if they are not to be included in the calculation, for example staircases, storage rooms or basements. Heated , but not ventilated rooms are set to not ventilated if they are to be included in the calculation but no ventilation components are to be output for the room.
Staircases, storage rooms and basements are initially automatically classified by the program as non-ventilated rooms. They are marked with an error indication in the building structure and an error message appears in the log.
By selecting the room type in the general room data, a room type according to DIN 1946-6 is already set here as a supply air, extract air or overflow air room. You can change the room type according to DIN 1946-6 without adjusting the room type in the general room data.
The following table contains an overview of all room types:
| Room type | Meaning |
|---|---|
| Supply air rooms | Supply air rooms are rooms into which thermally untreated outdoor air flows through outdoor air outlets or treated outdoor air (supply air) is supplied by means of ventilator-based ventilation. These are, for example, living room, bedroom, children's room, dining room, study and guest room. For ventilator-based measures of ventilation technology, a supply air factor is assigned for the scheduled distribution of the supply air volume flow rates, depending on the selected room type. This factor can be adjusted in the limits of the standard for each room. |
| Extract air rooms | Extract air rooms are rooms from which extract air is discharged directly through a ventilation shaft, an extract air outlet or a ventilator-based ventilation system. These are, for example, kitchens, bathrooms, toilets, showers, domestic utility rooms and saunas. |
| Supply and extract air rooms | Supply and extract rooms are rooms defined as living rooms with kitchenette. For supply air and extract air rooms, the volume flow rates are calculated separately for both extract air and supply air. |
| Overflow air rooms | Overflow air rooms are rooms that are located between a supply air room and an extract air room and connect these rooms with each other in terms of flow, for example corridors. |
| Unventilated rooms | Unventilated rooms are rooms that do not contain ventilation components, for example, storage rooms. Rooms that are not ventilated either have to be manually set to not ventilated or deactivated. Unventilated rooms are included in the calculation. |
| Deactivated rooms | Deactivated rooms are rooms that do not belong to the ventilated zone and are therefore not included in the calculation. These are, for example, staircases, unheated basements or attics. To deactivate a room and thus exclude it from the calculation, you have to select the room and deactivate the checkbox Ventilation room data. |
