How to model VFR ODU with AHU in DesignBuilder

I want to model VRF outdoor unit connected to DX cooling coil placed in AHU.

How do I do that or what is the workaround?

Ideally, I would like have VRF ODU which can be connected to a DX cooling coil located within an AHU (with AHU also having a enthalpy recovery wheel). But, it looks like VFR ODU can only be connected with VRF IDU in DesignBuiulder.

Please advise for modelling such systems.

regards, Prashant

Hey, fellow DesignBuilder user here. I actually sent a support ticket to DesignBuilder a few years ago regarding this, and got the following reponse:

The project ended up not using this setup anyway, so I didn't have to look more into it, so unfortunately I can't provide more detail on whether either of their suggestions worked.
