We just published the first release of DHNx!
With DHNx, we introduce a package for district heating network optimization and simulation models.
The aim of DHNx is to develop a library for the planning and modelling of district heating network systems. The package has two main features: the optimization (routing and sizing) of district heating network systems, and the hydraulic and thermal simulation of a district heating network with given pipe diameters.
Examples can be found here here.
We have just published the fourth release of the oemof.thermal repository.
With the fourth release of oemof-thermal we have validated the compression heat pump, the compression chiller and the stratified thermal storage using data provided by the Universidad Politécnica de Madrid and the energy supplier Naturstrom AG. The results are provided in the documentation.

We just published the third release of the oemof.thermal repository.
It’s time to proudly introduce a new component – the absorption chiller. Within the module we provide functions to calculate, among others, the characteristic equation, the coefficient of performance and the cooling capacity. See the documentation for more information.
All modules have been updated to oemof.solph v0.4
See the What’s new section for further details about the third release.
After oemof v0.3.2, we decided to make oemof’s structure more clear: Both, the framework (including e.g. TESPy) and the Package for energy system optimisation (using solph) were called the same – oemof. With the release of v0.4.0, there are now split packages for oemof.solph, oemof.network, and oemof.tools.
The third major version of TESPy – Mayer’s Merit – has been released together with a paper in the Journal of Open Source Software, available at the Open Journals website. The new version carries many new features, improved calculation stability for fluid mixtures and back end changes. Continue reading “TESPy v0.3.0 – Mayer’s Merit”

Please also register if you are already on this list, but you will have priority.
Looking forward to seeing you soon online!
Less than a week until the next user/dev meeting will begin. We set up a schedule for the meeting, which might be updated in the next days. We still have some free slots available to organize additional sessions.
For registering, please sign up here (scroll to the bottom). We still have some spots available. If you don’t have sufficient access rights, drop us a line here.
All registered people get access to the web conference. We’ll get in touch with you by mail. The meeting will be streamed including an option for Q&A via chat. The stream will be announced on the wiki page.
If you have any trouble or questions, please ask at contact@oemof.org
We just published the second release of the oemof.thermal repository.
A brand-new feature are the facade classes that simplify instantiating the components. Facades for these three components are now ready to be used: SolarThermalCollector, ParabolicTroughCollector and StratifiedThermalStorage.
The documentation has been revised and extended. The repository now has function tests, and the facades are tested with constraints test.
See the What’s new section for further details of the second release.
There will be a tutorial about the oemof.thermal repository at the upcoming virtual oemof developer and user meeting.
The oemof developer and user meeting, which was planned for May 13th-15th, will take place within the same time frame as a slimmed version in the virtual world.
The real life meeting in Bremen will be shifted to the second half of the year.
The agenda which is continuously developed can be found here: https://github.com/oemof/organisation/wiki/Meeting-May-2020-%28online%29
News concerning the registration process follow soon.
If you like to contribute a session, please contact us via: https://github.com/oemof/oemof/issues/59 Deadline for contributions is April 30th 2020.
The second major version (Clausius’ Circus) of TESPy has been released in January 2020 and version 0.2.1 – Fourier’s Fable just three weeks after. The release contains many back end improvements to facilitate future development as well as some new features. Continue reading “TESPy v0.2.x – Clausius’ Circus and Fourier’s Fable”
