<div dir="ltr"><div>Hello eQuest users,</div><div><br></div><div><div>I am currently modeling a LG VRF system in equest. I have used the LG performance curves for ARUB360B(D)TE4 which were exchanged on this list few days back. These curves include the heat recovery between the zones. I have also modeled the VRF system as per the LG MVIII_HR_Energy_Analysis guide. My results show 70% reduction in heating and 70% reduction in fan energy. This project has a DOAS with heat recovery as well. I have accounted for the heat recovery at the FCUs using the outside air heat recovery tab. This building is located in Oregon. Some of the anomalies I note - </div><div><br></div><div>- No space cooling savings </div><div>- Heat recovery reduces the space heating to some degree but there is a huge fan energy penalty</div><div><br></div><div>I have modeled VRF systems in the past mostly Daikin and they have worked well. Has anyone faced similar issues using the LG performance curves? </div><div><br></div><div>Thanks in advance<br></div><div><br></div><div>Best,<br clear="all"></div><div><font color="#000000" face="Times New Roman" size="3">
