Warning in HVAC system

1 post / 0 new

Hello Everyone,

I have modeled DOAS unit with chilled water circuit. I have used DOAS
modelling suggested by Energy-Models only change I have made in system type
: Energy Model suggest PVVT system but here chilled water provide cooling
to OA so I have model as VAV system. This DOAS unit is attached with
various VAV units to supply OA through specifying DOAS unit as OA system.

The warning is :
TFAU defined as an OA-FROM-SYSTEM
has OA flow requirement of 11971. CFM
But its calculated/specified SUPPLY-FLOW is only 10. CFM
Its SUPPLY-CFM has been reset to meet requirement, however it
is
strongly recommended you re-run with this SUPPLY-FLOW
specified.

Please help me out.

Thank you.

Regards,

Mayank
