Details on Component Detection in the Settings Ventilation
Information about the Component detection section of the Settings dialog in the Duct Network Calculation.
In this section, specify global settings for the detection of components, pipes and ducts that are to be considered during calculation.
You are here:
Layer
The layers are preset according the program specifications. The program recognizes different types of pipes, by the layer on which these pipes have been drawn.
Also detect 3D layers
Enabled: 3D pipes from the Design 3D Pipe&Power module are also included in the calculation.
Disabled: 3D pipes from the Design 3D Pipe&Power module are not included in the calculation.
Symbols..., Outside air..., Supply air..., Extract air, Exhaust air, Texts
Clicking one of the buttons in the layer selection opens the Select Layer dialog, where you can specify on which layers the respective elements are located.
Pipes in the Scheme
When setting up this section, keep in mind that a pipe network in the form of a pipe run scheme is only partially scalable at most. Edit the corresponding section directly in the calculation dialog to calculate the change in pipe lengths of a pipe section.
Enabled: The drawn pipe lengths and heights are determined during detection and multiplied by the entered factor. Since drawing is usually done at a scale of 1:1, the default factor is 1.
Disabled: The drawn pipe lengths and heights are determined during detection. If you have already edited pipe section data in the calculation dialog, the user-defined values are used.
Component selection:
Dropdown list with the options for component selection:
-
Detect all components: The entire pipe network with all components is detected and taken into account in the calculation.
-
Detect partial network: If you select the Detect partial network option, the dialog is minimized and you can select the desired partial network with the mouse in the current view. You can select or deselect the corresponding components individually with a selection frame or with the mouse pointer. Confirm the selection of the components with Enter. The number of detected components is displayed after selection.
If you start the calculation after selecting Detect partial network, the program asks you to reconfirm the selected components for the partial network. You have the possibility to change the selection of the components again or to start the calculation with the currently selected partial network by pressing the Enter key. An error-free calculation is only possible if the selected partial network is self-contained.
: Allows to reselect a subnet in the current view. This button is only activated if you have selected the option Detect partial network and have already made a component selection.
: Selects the selected partial network in the current view. This button is only active if you have selected the option Detect partial network and have already made a component selection.
Overwrite Edited Pipe Lengths
If you adjust the length of pipe sections in the calculation dialog where pipe component lengths were previously adjusted manually, these adjusted pipe lengths can be retained or overwritten. By default, when adjusting such pipe sections, a corresponding query appears which can be disabled and which activates or deactivates the option Overwrite Edited Pipe Lengths. If this query is deactivated, the Overwrite Edited Pipe Lengths checkbox allows you to change the current setting.
Enabled: Edited lengths of pipe components in a pipe section are overwritten when the length of the section is changed. The change in the pipe section length is divided proportionally between the lengths of the individual pipe components.
Disabled: Edited lengths of pipe components in a pipe section are not overwritten when the length of the section is changed. TThe change in pipe section length is divided proportionally between the lengths of the pipe components without edited lengths.
Search radius
The search radius specifies up to which value distances between components, if any, created during drawing, are tolerated when calculating the network. This function prevents inaccuracies in the drawing of component connections in the millimeter range from being detected as open ends and thus as errors during the calculation.
Room detection: Only detect rooms with mechanical ventilation
Enabled: Only mechanically ventilated rooms are included in the calculation of the air duct network.
Disabled: When calculating the air duct network, all rooms are included in the model. This can lead to a longer calculation time depending on the size of the model.
Modeled dimensions
You have the option of transferring the designed dimensions from the drawing to the calculation for the entire network or for the selected partial network, or to have the program determine the required dimensions.
Drop-down list: Specify whether you would like to transfer the constructed dimensions from the entire drawing, from a partial network (apply for selection) or not at all to the calculation. If you select the option apply for selection, the dialog is minimized and you can individually select or deselect the corresponding components for which the modeled dimensions are to be applied to the calculation using a selection frame or the mouse pointer. For the remaining components, the program determines the dimensions in the calculation. If you do not transfer any constructed dimensions into the calculation, the required dimensions for the components are completely determined by the program.
: Allows to reselect components in the current view. This button is only activated if you have selected the option apply for selection and have already made a component selection.
: Selects the selected partial network in the current view. This button is only active if you have selected the option apply for selection and have already made a component selection.
Applying modeled dimensions in calculation
When you start the calculation, the program asks whether the modeled dimensions should be included in the calculation. If you have selected the option apply for selection in the Settings, only the dimensions for this selection will be applied to the calculation when you confirm the application.
