Hello Nick,
I have the LG-Multi V Library included in a Bdllib.dat file. I found:
INPUT-TYPE COEFFICIENTS .. SYSTEM 770
$LIBRARY-ENTRY ARUN216BT3-CoolEIR-fEWB&OAT CURVE-FIT MultiV3(HP) SYSTEM 771
TYPE=BI-QUADRATIC-T COEF=(-1.12632880, 0.05474609, -0.00041054, SYSTEM 772
-0.01382520, 0.00014402, 0.00004546) SYSTEM 773
But not:
"ARUN216BT3-CoolEIOR-fEWB&OAT"
Are you sure the CoolEIOR is supposed to have the O included? I have attached the file in case it may be the one you are looking for. (Darn, ended a sentence with a preposition).

Subject: [Equest-users] Seeking some old LG VRF
Hi everyone!
I am working on an older eQuest model which utilized a set of VRF curves sourced from LG, which are of an older vintage than the sets I kept on record. To refresh memories, LG's recommended approach for estimating VRF system performance in eQuest historically (at least prior to recent advances with doe 2.3) involved using a modified library database (*.DAT) file, which per their procedure would be substituted over your base eQuest installation library file.
According to the BDL file written when trying to open the eQuest project, a number of library curves are missing, with the first one named as follows:
"ARUN216BT3-CoolEIOR-fEWB&OAT"
>From googling, it looks as though this is specifically a model of the Multi V III series. My oldest copies kept for the LG VRF libraries are for water source and air source Multi V VI series, unfortunately.
Does anyone have a copy of these specific curves, and/or that DAT file from LG in their records to share with me?
Thanks!
~Nick
