VRF Systems in HAP

Does anyone have any experience modeling a typical VRF system using HAP. I have attempted to model it through the wizard as a hydronic FCU then from there I was going to adjust the chiller part load performance to closer match my actual system. Any advice would be appreciated! Thanks.

Sorry, VRF's haven't caught on here yet. I cannot help, but it sounds like you could do this so long as it doesn't bring in unwanted pump motors. And pay attention to your controls kW so it doesn't get out of hand too. GL.

Just to update the situation a bit:

HAP now includes the ability to model VRF systems, I'm not completely happy with the way they implement performance curves, (I think they underestimated part-load performance), but at least the capability is there and they are trying to respond to customer demands.
