<![CDATA[Refrigeration system P-H Diagram]]>Hi All,

What's the best way to start/create a PH diagram in REXYGEN?

I'm going to try and create a working model for HIL testing

Cheers,

Thanks for the details. Currently, there is no direct support for such data representation.

For small-scale, I can imagine using the CNDR function block. You can also check the STEAM function block, but it appears the data you require is missing there.

There is also the possibility to use, e.g., Python or a C library if available.

Let me know your thoughts on this.

Regards,
Tomas

I'd like to be able to store and use this data so I can run a refrigeration model in REX. Once I've got a handle on it I'll share the model here for those that are interested.

Cheers
Mike

Thanks for your post. Please can you add more details about your intention? Are you looking for a solution to store or use such a dataset in your control algorithm? Or is the goal to visualise similar diagrams on the HMI screen?

Kind regards,
Tomas
