Results
Simulation results will be shown for the currently selected system diagram. Results may be called-up either from the Results menu or clicking the button (Display selection of results) located on the upper part of the window.
Further information on the meaning of the single values can be found in the User manual in the Simulation results chapter.
Attention: for the results to be displayed a system diagram must always be selected. The user will then be able to call-up the desired view from the Results menu. If since the last simulation data were edited or a dialogue box was opened and data were confirmed with OK the software will repeat the simulation process for the system diagram. If no data were edited or newly confirmed the results will be displayed directly.
If the system was incorrectly defined error messages will be displayed either during or after the simulation. The message Energy demand not met indicates that the calculated energy demand is not met in a considerable number of steps, i.e. the system cannot often rely on the amount of energy required to meet the calculated demand. A detailed analysis of component results will cue the user in on the possible source of error. In most cases components turn out to have incorrect settings.
Tip: review settings in the templates and compare them with your settings. For further details see the User manual in the chapter Controllers. The results may be displayed in different formats. Depending on the different user levels not all tables and graphs are available.
The following applies for all result display formats: Click the button (Print) to display a PDF file (see chapter Print). Click the button (Export results) to save results as a *txt file.
Tip: selecting the heading of the respective data sheet (the data sheet title will be framed in red) and pressing the Ctrl and C buttons results will be copied to the clipboard; from there they may be later entered in a different program such as Microsoft Excel.
Results Overview
The results overview enables the user to get a first idea whether or not the system was correctly defined. Only the most significant results are displayed; annual values are presented in a tabular format. The values appearing in the selected lines are displayed down below as a bar graph.
The result overview takes on a particular meaning if two systems appearing in a diagram are to be compared with one another. To this end set a system diagram as reference.
System Results
Here the monthly values referring to the entire system and the single current and fluid loops are displayed both in tabular format and as a bar graph. This display provides the user with an excellent overview of the most significant values.
Component Results
Here the monthly values referring to the single components are displayed both in tabular format and as a bar graph (always the values included in the lines selected within the table). This view proves very useful in analysing the functionality of the different components and searching possible sources of error.
Tabular Evaluation
This comprehensive table (available only in the Designer version) displays the hourly values of all components.
Tip: clicking on the button (Display selection window) a folder for the single components will be displayed. Double-click on the desired components. Finally select a value e confirm with OK. The table shows the corresponding columns.
Graphical Evaluation
This function enables a detailed and customised graphical evaluation of simulation results to be displayed. Proceed as follows:
- Select week or month.
- Click button „Add curve“.
- A window showing the folder tree for the single components is displayed. Double-click on the desired components. Finally select a value and confirm with OK.
- A curve showing the hourly values referring to the components selected for the indicated period is displayed.
- Further curves can be added for data comparison purposes.
- Selected curves may be deleted with button “Delete curve”.
Shift Curves and Optimize Scaling
Using the and buttons, curves can be shifted, and the scaling can be optimized, respectively. Tip: vertically improve scaling if curves run over the lower edge of the graph.
Week or Month
The shorter the selected period, the more precise will be the graphical representation of hourly values. The software is unable to display a detailed annual curve as the graph does not have enough pixels to display all values.
Tip: zoom in on the graph to gain even more insightful data. To do so hold the left mouse-button pressed and draw a square over a portion of the curve from the top left corner to the bottom right corner and release the mouse button.
Units and Axes
The graph has two vertical axes. This allows curves with up to two different units to be meaningfully compared with one another. The respective reference axis may be changed by clicking in the Axis column.
Colours and Lines
The user will be able to customise the graph choosing from a wide range of colours and lines. Colours ad lines can be edited with a simple click.
Save Graph
Clicking the button (Save graph) the selected graph can be saved as a *.png file.
Fluid Overview
The folder tree displayed by selecting this view shows which heat transfer fluid flows through which loop and the components the relevant loops consist of.
The fluid can be changed with the button (Change heat transfer fluid).
PDF Reports
Different PDF reports differing in level of detail are available depending on user level. These reports provide an ideal tool to present results to customers. Reports should be created only when the user is satisfied with simulation results and has already reviewed them in the other available output formats.
