Details on Calculation Presettings in the Settings for Potable Water
Information about the section Calculation presettings in the Settings dialog in the potable water trade.
In this section you can determine global settings for calculation. The settings are saved with the project. Exceptions are noted accordingly.
You are here:
Calculation presettings
| Element | Description |
|---|---|
| Detect material with every calculation | Enabled: Material for creating the parts list is detected with every calculation. Disabled: Material for creating the parts list is not detected with every calculation. For large project where changes in material are not to be expected, this can shorten calculation time. If this check box is deactivated and you use the command Print to create printouts, the question whether to detect material will be posed. These settings are not saved in your project but in an external configuration file and will be applicable to all potable water projects. |
| Printout pipe material per pipe type | Enabled: Pipe material for cold water, hot water and circulation are printed separately in parts lists. These settings are not saved in your project but in an external configuration file and will be applicable to all potable water projects. |
| Highlight most unfavorable flow path | Enabled: The most unfavorable pipe run will be highlighted after calculation. |
| Collect room book data | Enabled: If you have assigned rooms to the consumers by using the command Define ambience, you can print a room log after calculation under Output. |
| Dwelling station: apply design flow rate | Enabled: To calculate pressure loss for manufacturer specific dwelling stations, the flow rate from the dimensioning of the heat exchanger is used. Flow rate for this dwelling station is still method-specific. Disabled: To calculate pressure loss for manufacturer specific dwelling stations, the flow rate based on the method for pressure loss calculation will be used. |
| Calculate ejection time Testing temperature Testing period | Enabled: During calculation, ejection times for hot water consumers are determined. Select User-defined to specify your own values for the test temperature and the test time. When calculating the ejection time according to VDI 6003, you have to select a comfort level in the calculation parameters. For component types not covered by VDI 6003, you can specify the desired test temperature and test time manually. After calculation, you may print the printout Ejection time via Output, Form/Inspection sheets. For the SP 30.13330.2016 and SP 30.13330.2020 calculation methods, no calculation of the ejection time is performed and the range is not displayed. |
| Units | Opens a context menu where you can set the units for all values. The values in all dialogs about technical data of components, in the calculation dialog, in results and printouts will be shown in the specified unit. |
