 If you make a water-cooled VRF and name the water nodes the same as in this file, you should be able to add:

I was going through example files which talks about air-cooled condenser type. in airconditioner:VRF when I tried to select condenser type from air to water, it gives me error saying it needs to be connected to some plant loop. I played around generating one water condensing loop with 2 cooling towers but I am not able to do so. Can someone guide me on this? I need help modeling the VRF with water cooled condenser.
