Hi All,
I made a small correction to my question.
I am trying to model variable flow chiller system. Eventhough I made all branches ACTIVE except ByPass branches, it throws a fatal exception. Would greatly
appreciate your help.
** ~~~ ** This loop might be helped by a bypass.
** Severe ** plant flows do not resolve -- splitter inlet flow does not
match mixer outlet flow
** ~~~ ** Occurrence info=NEXTDAYSIM, 08/06 06:25 - 06:26
** ~~~ ** PlantLoop name= CHILLER1 CHILLED WATER LOOP
** ~~~ ** Plant Connector:Mixer name= CHILLER1 CHW SUPPLY MIXER
** ~~~ ** Mixer outlet mass flow rate= 131.191187 {kg/s}
** ~~~ ** Plant Connector:Splitter name= CHILLER1 CHW SUPPLY SPLITTER
** ~~~ ** Splitter inlet mass flow rate= 135.163143 {kg/s}
** ~~~ ** Check control type for branches between, components that
request flow should be ACTIVE control type
** Fatal ** Simulation terminated because of problems in plant flow
resolver
...Summary of Errors that led to program termination:
..... Reference severe error count=1
..... Last severe error=plant flows do not resolve -- splitter inlet flow
does not match mixer outlet flow
