[Bldg-sim] Modelling LG VRF Systems in eQUEST

[Bill Bishop]

Hi Syed,

See attached BDLLIB.dat file I compiled 6 years ago. I believe I started with the file that comes with the eQUEST DOE-2.2 installation and customized it to add all the curves I had from LG. The LG data starts on line 27146 through the end of the file at line 30324 and includes curves I compiled from three or four sources for LG equipment lines MultiV3, MultiV4 and MultiV5.

Regards,
~Bill

External Email: Treat links and attachments with caution.

Hi all,

I'm currently modeling an LG VRF system in eQUEST and need the BDLLIB.DAT file referenced in the VRF guide below:

https://legacy.lghvac.com/resource-service?filename=VRF-EM-eQUEST-ModelingGuide_US.pdf<https://legacy.lghvac.com/resource-service?filename=VRF-EM-eQUEST-ModelingGuide_US.pdf&utm_source=chatgpt.com>

Could you please provide the LG BDLLIB.DAT file used to obtain the performance curves for the LG ARUM and ARUN series VRF systems?

Thank you in advance for your help.

Best regards,
Syed Hussaini, P.E., C.E.M.
Senior Energy Engineer
