How to normalize experimental data to a performance curve?

edit

@rraustad Are the rated conditions values in the energyplus documentation? At the very least, the code must contain the reference conditions because the curves are being evaluated at the rated conditions and output is checked to be 1.0 plus minus 10%.

19.44 C (67 F) indoor wet-bulb and 35 C (95 F) outdoor dry-bulb temperatures are typically used and called out in AHRI standards. I'm sure these are in the docs.

@rraustad You are correct! The cooling coils tend to have the test conditions values in the explanation of the curve field, but another good place to look is the related fields like COP which can have the test conditions values instead like in some of the heating coils documentation in the Input Output Reference.

I just used the AEDG VRF with DOAS measure. It generated one outdoor unit and 21 indoor units. So far, so good. Furthermore, the cooling CapFT curve looks more or less plausible, but the heating CapFT and the cooling and heating EIRFT curves not so much. I believe I have a good idea what these are to look like as I spent weeks scrubbing Daikin data. I noticed in particular that none of the AEDG VRF with DOAS EIRFT curves pass through 1, as they should at the rating conditions. I believe this causes unrealistically low energy consumption numbers. Any thoughts, anybody?

The VRF data I had when the VRF example file (VariableRefrigerantFlow_5Zone) curves were created did not use the rating point (if the AEDG/DOAS curves are the same as those I created). So a warning is issued with the VRF example file. But the curves themselves along with the rated capacity and COP should provide the correct result. If those fields are autosized, then I believe there is an issue, although moderate (because the selected rating was close to the AHRI condition). I have been meaning to correct this but because I believe the results are fairly accurate I have been procrastinating.
