Has anyone attempted to simulate a VRF system with a full airside economizer and do you have any direction you may give? Ideally the goal is to have an oversized DOAS allowing for full economizer operation when the OA temperature is below the temperature lockout. If the OA temperature is above the lockout then the DOAS just provides room neutral air and the VRF handles any subsequent latent and sensible load at the fan coil.
I've yet to attempt this myself, but thought I would reach out and see if anyone has modeled this system and control before, and see if they had any information to share.
