Repository with aVaporCompressionLibrary inPython for steady state process design and simulation.It enables use of RefProp and CoolProp as well as different compressors, heat exchangers and flowsheet configurations for heat pumps and chillers.

To install, run

pip install vclibpy

To use RefProp, you have to buy the licence and obtain a valid .dll file.

In order to help development, install it as an egg:

git clone https://github.com/RWTH-EBC/vclibpypip install -e vclibpy

We recommend running our jupyter-notebook to be guided through ahelpful tutorial.
For this, we prepared several examples, which we encourage to check one by one.To use, you can either run the code locally or in abrowser using juypter-notebook:

If the web-hosting is not available, you can run the notebooks locally with the following code:

pip install jupytergit clone https://github.com/RWTH-EBC/vclibpyjupyter notebook vclibpy/docs/jupyter_notebooks

Or, clone this repo and look at the folderexamples.Those examples are the same as the jupyter notebooks.
