[Equest-users] Split units with multicompressor

[GK Pandian]

Sambhav,



I don’t think equest have multi compressor model option. My suggestion
would be, this energy savings in multi compressor should be accounted in
system rated EER/COP. Please check with unit manufacturer.

Also make sure that, you are assigning system EER after deducting the
supply fan power in order to model supply fan power separately.



Hope it helps!



Thanks

Gopi
