eQuest & Mitsubishi VRF systems

It is my understanding that Mitsubishi and Daikan funded development of
DOE2 VRF routines that run under EnergyPro and VisualDOE using DOE2.1E,
and there may be some problematic challenges
hindering simple implementation in eQuest.
Will see if I can elicit comment on this topic from eQuest's dynamic,
talented and decidedly underappreciated developers, who tirelessly toil
day and night on our behalf. Perhaps we can show our appreciation for
them by all lobbying our local Mitsubishi / Daikan reps to secure
funding for a port-to-eQuest effort. After all, updating to eQuest it
seems would be in the manufacture's best interests, with usage of
variable refrigerant flow systems gaining traction in the marketplace.

As a short-term workaround, am following up on a rumor that there may be
a way for an eQuest parametric run to be manually edited to reference
these routines, provided they can be obtained. Will also see what I can
do about actually obtaining them. This isn't a purely altruistic
gesture, I too am working on a VRF system.

More information forthcoming, hopefully...

Thanks for your response. I will check with the VisualDOE folks to
find out if there that is a viable option at this point.

Has anyone tested this system in TRACE? It is a system selection.

My understanding is that both Mitsubishi and Daikin worked with Martin Dodd (from EnergySoft) on the VRF/VFRZ routines.

As such, for California users of EnergyPro (EnergySoft's program) can download the VRF/VFRZ routines. There are libraries for Mitsubishi and Daikin.

We've done some preliminary runs with them in our office with them.
