Seeking some old LG VRF

6 posts / 0 new
Last post

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"

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

Hi Nick,

I have a copy of the Multi V IV series, it's not the V-III but it still is older than what you have.
I'd be interested in getting your V-VI series though if you can share it.

Hope it helps you out.

Thank you Patrick!

Unfortunately, I mistakenly typed VI when I meant IV? so these are the vintage of libraries I kept on record as well.

If I had anything newer I would happily share though, to be sure ;-)!

Hahaha typo mistakes sometimes really shift what we want to say!

At least I?m a little relieved, I thought I spaced out on V-V AND V-VI when I looked at my files?
I thought for a moment that I missed a few things? Happy to see I haven?t ?

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).
