Modeling of heating substations

[efjerb]

Is there any support for heating/cooling substations, e.g. shunts with recirculation or a heat exchanger, to regulate supply temperature to subsystems and heating/cooling coils. See picture for example:

Full support would allow users to distinguish points on the primary and secondary side of the heat exchanger/shunt. Relevant points on either side are:

• (Primary/Secondary) Entering temperature
• (Primary/Secondary) Leaving temperature
• (Primary/Secondary) Flow
• Valve position (usually a valve placed on the primary return or a threeway valve)

Hi @efjerb ! Thanks for your question. The short answer is, I don't think we have all the concepts required to model this in the way that you are asking, but I think we do have most of them. We have all of the point classes, for example, but they don't differentiate between whether they are on the primary or secondary side of the system. We could definitely consider adding primary/secondary concepts to Brick (these might be isPartOf the heat exchanger), and then the points could be associated with those primary/secondary components.

You may also want to take a look at the 223P metadata ontology (https://open223.info) which does allow you to get much more precise about how these systems are put together. We are designing Brick and 223 to work together, so you might use 223 to model pipes/connections, and then use Brick to name the points.

I would encourage you to come to one of the Working Groups (https://brickschema.org/blog/working-groups/) to discuss this further, if you can make it! I'm also happy to continue the discussion here
