Minutes

Expert meeting

10+5 min presentation about 1.1

Break-out sessions (4 sessions, about 50 min each, one being about data-driven models)

Possible sessions:

  • updates from the different libraries (5 to 10 min each)
  • borehole models and measurements (Christian, Massimo, Michael)
  • Control Description Language
  • Building modelings (Spawn of EnergyPlus, IDEAS/Floorspace.js)
  • airflow model implementations in IDEAS, and what to add to IBPSA.

Control Description Language

See http://obc.lbl.gov/specification/cdl.html

ASHRAE Standard 231P authorized in June 2020.

For now, don't move to IBPSA library, but consider changing IBPSA.Controls so they are compatible with the CDL implementations.

Refrigerant media

No update, currently in review at NIST.

CONTAM-style models (Klaas)

Filip to work on integration in IDEAS library, as part of zone model.

Update on geothermal models (Massimo)

No update.

Visual enhancements of PartialTwoPort, e.g., refactor tank

Consider refactoring tanks to have ports at the top and bottom, see notes at https://github.com/ibpsa/modelica-ibpsa/issues/1280

Todo: Refactor tank to have inlet and outlet at top and bottom. At top and bottom, make optional a vectorized fluid port. Default is a single port.

Scope for fluid systems

See https://github.com/ibpsa/modelica-ibpsa/issues/1385

Change to CVode as default solver (Michael)

Michael made a PR.

Progress on pull requests

All should work on the pull requests or open tickets.

New action items

None.

Previous action items

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.
