Dear All,
Sorry for posting again. I found it very strange for the node connection of PARALLELPIU:REHEAT
Again, when I did SingleDuct:ParallelPIU:Reheat. Here is what I define.
I define Fan:ConstantVol as
SPACE1-1 PIU Secondary From Zone, !- Air Inlet Node Name
SPACE1-1 PIU Fan Outlet; !- Air Outlet Node Name
And I define:
ZoneHVAC:EquipmentConnections,
SPACE1-1, !- Zone Name
SPACE1-1Equipment, !- Zone Conditioning Equipment List Name
SPACE1-1 Supply Inlet, !- Zone Air Inlet Node or NodeList Name
SPACE1-1 PIU Secondary From Zone, !- Zone Air Exhaust Node or NodeList Name
SPACE1-1 Zone Air Node, !- Zone Air Node Name
SPACE1-1 Return Outlet; !- Zone Return Air Node Name
The warning shows:
** Warning ** Node Connection Error for object UNDEFINED, name=SPACE1-1 PIU FAN
** ~~~ ** UNDEFINED not on any Branch or Parent Object
** ~~~ ** Inlet Node : SPACE1-1 PIU FAN OUTLET
** ~~~ ** Outlet Node: UNDEFINED
If I open the .bnd file, I found that Fan:ConstantVolume is not defined.
Component Set,47,UNDEFINED,UNDEFINED,FAN:CONSTANTVOLUME,SPACE1-1 PIU FAN,SPACE1-1 PIU SECONDARY FROM ZONE,SPACE1-1 PIU FAN OUTLET,Air Nodes
also this makes AIRTERMINAL:SINGLEDUCT:PARALLELPIU:REHEAT as
Component Set,39,AIRTERMINAL:SINGLEDUCT:PARALLELPIU:REHEAT,SPACE4-1 VAV PIU REHEAT,UNDEFINED,SPACE4-1 PIU FAN,SPACE4-1 PIU FAN OUTLET,UNDEFINED,UNDEFINED
but I already put Fan into the AIRTERMINAL:SINGLEDUCT:PARALLELPIU:REHEAT
