Heat Pump and Organic Rankine Cycles
====================================

Heat Pump
----------

For heat pumps of this simple structure (so far).

As one of the outputs, one gets such plots:

Organic Rankine Cycle
---------------------

Organic Rankine cycles with this structure are modelled:

Typical results (here for a mixture) look like this:

Cycle Structure
---------------
    
The structure of cycles are read from excel files 
, to create the structure plot, as shown above. **graphviz** must be installed on the computer 
to use this script. An exemplary excel-file is found in the **data**-folder.
Here is the first page of it.
