v1.3.0 -- Pacy Portrayal

New Features

• Fast reload of precalculated state diagram isolines
• New refrigerant CO2 (R744)

Improvements

• Improved state diagrams
• Better and more robust handling of errors and missing data during state diagram creation
• Extended usage example

Fixes

• Total and specific investment cost calculation was missing the mutplication factor. Previous results where too low by a factor of 6.32
• Heat sink feed flow temperature was limited below the refrigerants critical temperature. This makes no sense for transcritical heat pumps and was therefore changed for those heat pump setups. Hence, this update is necessary for usage of transcritical heat pumps through the dashboard. The models themselves were not limited and are therefore not affected by this flaw.
• Fix some topology schemas that where missing labels

v1.2.0 -- Cool Cascading

New Features

Existing stock of heat pump models was widely extended by two-cycle cascade heat pump model versions. Thank you to @bilwint.

Tests

Basic framework for automated tests of models was created using pytest.

Stability Regained

This version is a patch for v1.1.0 and v1.1.1, as the update of the underlying TESPy version introduced some instabilities at high heat sink return flow temperatures.

Thank you to @bilwint for finding and resolving this issue.

Hotfix for v1.1.0

Hotfix for v1.1.0 TESPy Update. Heat pump model class HeatPumpFlash was left out in upgrading for TESPy v0.7.x and is fixed in this release.

TESPy Update

All heat pump models are updated to work with the latest TESPy version 0.7.5. Furthermore, an API is added to easily get the default parameter files of a specific heat pump model class.

Initial Release

Initial release of the heatpumps package. It contains a comprehensive library of heat pump model classes, as well as a powerful dashboard to visualize, simulate and analyze them.
