FrieTec Software GmbH

The EcNetz program system calculates the flow and temperature conditions in pressure piping networks of any type for compressible and incompressible media. The results can be analyzed, printed in list form and graphically displayed in the form of calculation networks and diagrams.

general functions

PC with Pentium processor and 16 MB main memory extension (recommended 32 MB). Windows 95/98 or Windows NT 4.0 operating system – Microsoft compatible mouse

Up to 100,000 elements (strands, customer systems and pumps / pressure reducers)

Any network topology

Regulated or unregulated pressure increases (DEA) or pressure reductions (DMA) in meshed or unmeshed power supplies.

Regulated DEA or DMA can be controlled via network pressures at certain nodes and / or flow rates in the control valve; Unregulated DEA or DMA can be defined with their characteristics.

The roughness can be specified as a material-specific value with the DN table, as a general value or as a string-specific value. The length addition factor can be specified as a general value or as a string-specific value.

Inner diameter u. Roughness for strands can be taken from the DN tables defined by the user. Over twenty prepared DN tables are supplied according to different standards!

For pipelines with special hydraulic behavior (eg Flexwell pipes) Q-H characteristics can be defined. The DN table for Flexwell pipes is included!

Resistance coefficients can be specified for each string individually or element-related via resistance value tables. For T-pieces and reducers, the flow-dependent drag coefficients can be determined automatically.

Any number of customers per network node.

Breakdown of customers into different customer groups, which are taken into account with different multipliers or also with hydrographs (refined simultaneity model).

Consumption data can be specified as annual values, monthly values ​​or any other equivalence values.

Multiple subnets can be managed and counted together in a single record or in separate records.
Mask-controlled menu navigation u. Data entry with plausibility checks.
Recording the network topology with digitization modules based on AutoCAD, MicroStation.
