RE: [EnergyPlus_Support] Compact HVAC simulation warnings

["Minu Agarwal" <Minu.Agarwal@xxxxxxxxxxxxxxx>]

Hi Everyone,

I am trying to set up an HVAC system with four zones all served by one
AHU. Each zone has VAV with reheat. The return streams from the zones
are collected together using a mixing box.

I keep getting the following node connection errors. After much brain
racking I am not able to indentify the source error. Can some one point
me in possible directions? The most puxxling is err 3 which says
controlled zone not among zones. Why does it now recognise the zone
here?

 

1) ** Severe  ** Node Connection Error, Node="MAIN_LOBBY IN NODE",
ZoneInlet node did not find an outlet node.

   **   ~~~   ** Reference Object=CONTROLLED ZONE EQUIP CONFIGURATION,
Name=CELLER_LEVEL_C01_MAIN_LOBBY

 

2)    ** Severe  ** Node Connection Error, Node="ZONE EQ IN NODE", Inlet
node did not find an appropriate matching "outlet" node.

   **   ~~~   ** If this is an outside air inlet node, it must be listed
in an OUTSIDE AIR NODE or OUTSIDE AIR INLET NODE LIST object.

   **   ~~~   ** Reference Object=ZONE SUPPLY AIR PATH, Name=ZONE SUPPLY
AIR PATH 1

3)       ** Severe  ** Controlled Zone Equip Configuration: Requested
Controlled Zone not among Zones, requested
zone=CELLER_LEVEL_C01_MAIN_LOBBY

 

Any heal would be greatly appreciated

 

Minu
