Welcome to the official online documentation of heatpumps. Try it out right now!

Streamlit App

Key Features

  • Steady-state simulation of design and partload operation based on TESPy

  • Parametrization and result visualisation through a Streamlit dashboard

  • Industry standard, as well as topologies still in research and developement, supported

  • Sub- and transcritical processes

  • Wide variety of refrigerants due to the integration of CoolProp

Structure

This documentation is grouped into the chapters below. It first introduces the tool, followed by its methodology and a galary, before it is concluded by a chapter on what and how to contribute to heatpumps.

Getting Started

This section introduces you to heatpumps’ usage. It starts with an explanation of how the installation of the tool works. Right after, you are shown how to use the streamlit dashboard to simulate different heat pump topologies usind a variety of refrigerants. If you would like to dive deeper, e.g. if you need more granular control of the simulation(s) or to integrate it into a wider workflow, you may want to use the python model classes directly. These heat pump model classes are therefore introduced in the final section of this chapter.

Documentation

The Documentation chapter goes deeper where the Getting Started one stops. It contains a thorough explanation of the methodology used, as well as the full model API. Futhermore, a change log documents the developement process and the Bibliography holds all references mentioned within the whole online docs.

Galary

Example applications as well as scientific publications using heatpumps are collected in the Galary chapter.

Development

The Development chapter contains information on what and how you can contribute to the developement of heatpumps. This can be as easy as reporting a bug you stumbled upon while using heatpumps or requesting a feature you feel is missing currently.
