Using the ThermoCycle Modelica library

We will now have a look at the ThermoCycle Modelica library.
As a first thing we need to load the ThermoCycle Modelica library on Dymola 2015. To do so you can have a look at GettingStarted.

Once you have loaded the library, click on the ThermoCycle package in the package Browser window of Dymola. The following should be displayed:


The ThermoCycle library is hierarchically structured into different packages, listed below:

  • Components is the central part of the library. It is organized in three sub-package: FluidFlow, HeatFlow and Units. It contains all the models available in the library from the simple cell model for fluid flow to complete model of heat exchangers, expanders and control unit.
  • Examples contains models where the components of the library can be tested. It includes several ORC plant models and it also provides a step by step procedure to build an ORC power unit.
  • Functions are the empirical correlations used to characterized some of the models presents in the library.
  • Icons define the graphical interface for some of the models in the library
  • Interfaces defines the type of connectors used in the library. The flow connectors are available for compressible, incompressible and perfect fluid model.
  • Media contains a list of some of the fluid available in the library. The fluids in this package are labeled with the acronym TC. The ExternalMedia¬†library is anyway necessary to allow the coupling with CoolProp for computing the thermo-physical and transport properties of the fluids.
  • Obsolete is a storage of some old models that are replaced by new ones during the development of the library but that are still used in some examples.

The main packages are further divided into sub-packages and models. In ThermoCycle, each model has a relative documentation explaining the main features. To access the documentation layer of each model you can click on the INFO icon on the Dymola menu as shown in the picture below.
