TPEx currently accommodates this scenario and is the best option available. While TPEx does require that the product data (make/model number) be input by the manufacturer, once a product has been added, performance data can be added by any user. I would encourage you to reach out to LG, explain the situation, and ask them to add the product data for their water-cooled units. Once they've done that, you can input the performance data you have and the TPEx to BCL translators will automatically create the OpenStudio components for you.

No problem. You'll need to use the ZoneHVAC:TerminalUnit:VariableRefrigerantFlow object.

Yes, cassettes can be referred to as indoor units (they're a subset type of indoor unit). I don't believe that you can currently add more than one terminal (indoor) unit per zone, so you'd either have to divide up your thermal zones, or create a fictitious aggregate cassette that mimics the performance of the smaller units.

The recently added OpenStudio VRF drag-and-drop capability (see here) allows you to pull in actual VRF components from TPEx via BCL. LG is currently the only manufacturer to provide data sufficient for modeling, but they have contributed their entire VRF Multi V line, which includes 52 outdoor units and 79 indoor units (of which 21 are ceiling cassettes).

The intent is for future TPEx technology categories to align with Standard 205 annexes (assuming such annexes exist when the TPEx technology category is added). As Standard 205 annexes are published for existing TPEx technology categories, if differences in the technical data request exist, we would like to revise the TPEx data entry forms to bring them in-line with the Standard 205 documents.
