<p>Hi all,<o:p></o:p></p>
<p>I’m currently modeling an LG VRF system in eQUEST and need the <strong><span style="font-family:"Aptos",sans-serif">BDLLIB.DAT</span></strong> file referenced in the VRF guide below:<o:p></o:p></p>
<p><a href="https://legacy.lghvac.com/resource-service?filename=VRF-EM-eQUEST-ModelingGuide_US.pdf&utm_source=chatgpt.com" target="_blank">https://legacy.lghvac.com/resource-service?filename=VRF-EM-eQUEST-ModelingGuide_US.pdf</a><o:p></o:p></p>
<p>Could you please provide the <strong><span style="font-family:"Aptos",sans-serif">LG BDLLIB.DAT</span></strong> file used to obtain the performance curves for the LG ARUM and ARUN series VRF systems?<o:p></o:p></p>
<p>Thank you in advance for your help.<o:p></o:p></p>
<p>Best regards,<br>
Syed Hussaini, P.E., C.E.M.<br>
