12th International Symposium on District Heating and Cooling

The <strong>12th</strong> <strong>International</strong> <strong>Symposium</strong> on District Heating and Cooling,September 5 th to September 7 th , 2010, Tallinn, Estoniab) Directly input (or import) of the heat source (redpentagon on the top left in the Fig. 7, through violetcircle marked) and the sinks (customer – yellowflags in the Fig. 7, as house service connectionstations in the house lines arranged) with the givenattribute for the heat demand.c) The input of possible routes (thick green lines inFig. 7) by using the mouse and the assignment ofthe attributes (table in the right section of Fig. 7),for quite available pipes with attribute(branch pipe from the source inDN 150 – input value:ground,channel).for the laying procedure () andfor street andfor cellar corridor and availableStep 2: Providing the non-geographical dataThe files with the non-geographical data (generalentries to the network as for example mediatemperatures as well as economic data) are entered onforms.Step 3: Generating the network topographyAfter the import of the files invested by the GIS thenetwork topography of the possible routes is created bythe program. Gaps between the inputted routes (step1c) are complemented by the program to a graph withentire and varied development.Step 4: Verification of the generated networktopographyWith this step the files generated by the program canbe imported in the GIS: The generated edges (thin bluelines in Fig. 8) and vertices (blue dots in fig. 8)complete the entered network topography and can bechecked.Step 5: Determination of the optimal developmentThe route optimization is carried out by the program.Step 6: Evaluationa) Output of a result report and export of theoptimization results to the GIS.Fig. 8 step 4324
