In recent years, optimization of district heating systems has been occurring, thus reducing
maintenance costs and emissions. In addition, appropriate dimensioning of the system can
be done to reduce initial costs. Optimization is performed with software tools that enable
simulation of thermo-hydraulic conditions of the district heating network. They have a user
interface that gives the user a better idea and easier data management, but they have to be
paid for.
In the master's thesis, an analysis of the thermal and hydraulic conditions of the district
heating system is performed with an independently developed Python simulation tool. For
the analysis of thermal and hydraulic calculations, we used the Python library for simulation
of thermo-energy systems. After importing the network data and defining the boundary
conditions, the simulation tool enables the calculation of the district heating network and the
visualization of the network and results. The calculations have a high accuracy close to the
boundary conditions obtained by calibration, which decreases with deviations from the
obtained boundary conditions.
