Details on Room Data

Information on the Room data section in the Rooms dialog of the Duct Network Calculation.

You are here:

Project tabVentilation disciplineAnalyse tabRooms

Room data Linear Revit

All room-specific data, if available, is read from the properties of the spaces. This includes, for example, the dimensions, the room temperatures, the cooling and heating capacity as well as the room name and room number.

If you change room data here, this data will be saved in the spaces after confirming the dialog. If you delete a changed value again, the program resets the value to the original value from the space.

Room mechanically ventilated

Enabled: This room is taken into account when determining the minimum volume flow rates and the sound level calculation and is mechanically ventilated via air outlets.

Disabled: This room is not mechanically ventilated and is not taken into account when determining the minimum volume flow rates and the sound level calculation. The room is marked accordingly in the tree structure.

Dimensions

Length, Width, average Height

Displays the values for the length, the width and the average height of the room read out of the spaces.

Area, volume

Shows the values for the area and volume of the room calculated from the values of the space.

Temperature and air humidity

Room heating, room cooling

Displays the temperatures read from the space for heating and cooling.

Room air humidity

Shows the humidity read from the space.

Supply air heating, Supply air cooling

Specifies the temperature of the supply air to heat or cool the room with the ventilation system to the temperature specified in the Room temperatures section.

Room load

Heating load, Cooling load

Shows the determined heating or cooling load of the room. The values are read from the properties of the space and can be adjusted manually.

Sound level calculation Room

Spatial form

The spatial form is determined based on the spatial geometries of the room data. The spatial form can be changed manually. The following graphic shows the criteria used to determine the spatial form.

Room type

Select a room type to perform a sound level calculation. After selecting the room type, the other fields are filled with values according to the selection.

Opens the dialog Permitted sound levels in dB(A), in which you can obtain a list of room types, including permissible sound pressure levels and reverberation periods, and create your own room types.

average reverberation period

The average reverberation period is taken from the dialog Permitted sound levels in dB(A) after the room type has been selected.

Absorber area

The absorber area of the room is calculated from the room volume and the average reverberation period.

Sound level decrease after center range.

Defines the value in dB in flat and long rooms by which the sound level decreases after the transition from the center range to the diffuse range. A pure diffuse range is assumed for cubical rooms.

Permitted sound pressure level

Specifies the sound pressure level to be maintained in the room.

Sound pressure level measuring point

Specifies the sound pressure level resulting from all air outlets existing in the room. This value should be lower than the permitted sound pressure level.
