Minutes

Reduced order models

ROM building model from ISO 13790 (from Aalborg University). 5R1C model. ISO standard states it is meant for monthly simulation, not for hourly.

VDI 6007 uses 7R2C, with different capacity for internal walls.

Applicable to situations that have fewer data than what is needed for TEASER.

Has implemented model in Modelica; Model needs about 15 parameters.

Uses Blender for model authoring, with BAGEL add on (Blender-based Automatic Generation of Energy Loads), via Mustache template.

Maybe want to consider adding inputs for latent and sensible load, which was added later to current ROM model in IBPSA.

Alessandro can start implementation on IBPSA library.

Refrigerant media

Refrigerants is in review process.

For VCLib, is in progress. Uses performance maps with 1st order dynamics.

Ethylene glycol

/~https://github.com/ibpsa/modelica-ibpsa/issues/1410 Now on the master branch.

Steam media

No update for this meeting.

CONTAM-style models (Klaas)

PR /~https://github.com/ibpsa/modelica-ibpsa/pull/1437 is ready to merge and then review for later merge to master.

Massimo to make first review.

Update on geothermal models (Massimo)

No update to show yet on implementation of new method for borefields.

Dymola 2021x and MSL 4.0.0

Dymola 2021x works if MSL 3.2.3 is copied.

Visual enhancements of PartialTwoPort

Issue /~https://github.com/ibpsa/modelica-ibpsa/issues/1280.

See notes on ticket.

No work yet.

Progress on pull requests

No discussion.

New action items

Michael to schedule next calls.

Previous action items

Michael to go through issues and maybe mark as "won't fix" and close for now to keep it more manageable.

Klaas to make pull request for new air flow models.

Fluid Property models (RWTH) RWTH intern development of R134a, R410A, R32, R407C, R290 and R744 merge in December, Paper in March Are there further fluid models of interest? We can add some more due to master's thesis.
