Minutes

Condensing coil model

Discussion of https://github.com/ibpsa/modelica-ibpsa/issues/1109#issuecomment-507283640

Donghun presents slides about Fuzzy Modeling approach applied to cooling coil model.

Donghun to look into https://github.com/ibpsa/modelica-ibpsa/pull/1113 and discuss with Filip offline.

Regression testing

Need to design how/where to store results on a server. Antoine to make specification and share it with Michael Manns.

Actuator model revision

Latest revision at https://github.com/ibpsa/modelica-ibpsa/pull/1189.

Antoine will enter an overview of parameter changes to be clear what changes, and afterwards make the change.

Antoine to run the large models in the Buildings.Examples package to verify that model is robust.

Antoine to benchmark C1 implementation of pressure-independent damper. For MPC, may need to replace this model with a C2 model (that does not output the actuator position).

New media R290

No update since July. Christian Vering to address https://github.com/ibpsa/modelica-ibpsa/pull/1180#issuecomment-512983189.

Geothermal model

No update.

Student of Massimo will start in September.
