Trouble using VRF components from the BCL in OpenStudio app v1.9

edit

Hi Denis,

Thank you sir for your very helpful information!

I can confirm that both the DAIKINREYQ 72 and the Fake VRF Outdoor Unit work with the default VRF indoor unit. I also tried the outdoor LG units with the default VRF indoor unit, but, as you mentioned, I encountered "FATAL" errors when trying to run a simulation. Thanks again for your help!

Good to know. Have you tried the Mitsubishi units (added as a default library)? These work.

Yes sir, The Mitsubishi units worked perfectly when added as a default library. I genuinely appreciate your detailed guidance and assistance with this matter.

Super! Great work @Ski90Moo. If you found the answer satisfactory, it is customary to accept it by clicking on the checkmark. Helps others in the future.

Thank you. Yes, you can get the LG objects to work, but you will need to do some editing to the curves (OS:Table:Lookup). Some of the LG lookup tables are missing a field. For example, the !- Heating Capacity Ratio Modifier Function of Low Temperature Curve Name only has Output Values up to 119. The independent variables have 8 and 15 values, so the total dependent variables (output values) should be 8*15=120. They count up in groups of 15 at which point it starts with a low number and starts counting up again, so you should be able to spot where it is missing.
