Modelling of complex thermal energy supply systems based on the Modelica-Library FluidFlow
(2009)Abstract
The new Modelica library FluidFlow is being developed for the thermo-hydraulic simulation of complex energy supply systems. This library includes standard hydraulic model classes and specialized components for HVAC-systems and solar thermal systems. Most of these Modelica classes are modelled with equations of the 1Dtransient energy transport. The validation of the library takes place both by measuring values from test stations and by comparing with detailed CFD models. A first complex use case of the library represents the simulations-based design of a complex thermal energy supply system of a residential area, as a part of a newly built city in Iran.
