Since 90.1-2016, DX DOAS units have ISMRE requirements to be rated per AHRI 920. While this is a great way of better comparing newer units, it is a packaged performance metric that as far as I can see, has no direct translation to EnergyPlus inputs.

In order to correctly account for DOAS capacity, the way I see I either can:

  • Try to back-calculate performance curves based on the 4 points from the standard conditions. I do not think this would be possible/accurate.
  • Ask the manufacturer for DX coil performance points: So far our rep has no idea if this is even available.

I do not see any issues on github regarding this metric, so I am reaching out to anybody for clues to look for clues.

Were you able to figure this out? I'm facing the same question now (looking at eQuest modeling, but any strategy would be helpful).
