Minutes

Continuation in July 2022

WP 1.1 not only serves as library development, but also as an exchange of developer information. Value of component deployment is large. Would be good to also have a list of components that are of interest.

Reduced order models

Next is implementing it in the library with a fluid volume to allow connecting a HVAC system.

Steam model

https://github.com/ibpsa/modelica-ibpsa/pull/1395

Is 2nd review from non-LBL needed? No, go ahead and merge.

Plug flow pipe

https://github.com/ibpsa/modelica-ibpsa/issues/1494

Mixing volume represents first order filter as plug flow is highly idealized. Filip sees no strong reason for keeping multi-port. Aim for consistent model interfaces.

Look into whether the mixing volume vol should be implemented in the core model on the inlet and outlet? Current model is also not symmetric which is not good.

Refrigerant media

No update.

Filter for movers and actuators

https://github.com/ibpsa/modelica-ibpsa/issues/1498

Remove order as a parameter, change parameter order to a constant (Filip sometimes sets it to 1).

CONTAM-style models (Klaas)

Filip works on review. Klaas working on correcting style and Filip to review.

Update on geothermal models (Massimo)

Will soon start on implementation in Modelica for new transfer functions.

Visual enhancements of PartialTwoPort

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

See notes on ticket.

No work yet.

Progress on pull requests

Ongoing.

New action items

None.

Previous action items

Klaas to make pull request for new air flow models. Ongoing.

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.
