The release notes for Openstudio 2.9.0, and linked discussions on github, indicate that water cooled VRF has been implemented in OS 2.9.0, and that modelling such can be done in the app.

I am looking through the app for a method to implement a water cooled VRF and I see no obvious way to do this.

• There is no condenser type option on the VRF System
• Dropping the VRF System (from my model, not the Library) onto a Condenser plant loop demand side will crash the app.
• Default is air-cooled, and this is what I see in the idf

Can someone please explain in simple clear terms how to set up a water cooled VRF in OS 2.9.1

Thanks
