I have a problem with the plant flows when I change the control type temperature in a HVAC Radiant System
I have a simple loop for HVAC radiant system. I use the next object
Object: ZoneHVAC:CoolingPanel:RadiantConvective:Water
Field: ControlType
Default: MeanAirTemperature
Everything is ok, without warnings but when I change the ControlType to “MeanRadiantTemperature” or “OperativeTemperature”. I get the following error:
** Severe ** Plant flows do not resolve -- splitter inlet flow does not match branch outlet flows
** ~~~ ** Environment=SUMMERWEEK, at Simulation time=04/02 01:30 - 01:40
** ~~~ ** PlantLoop name= CHILLED WATER LOOP
** ~~~ ** Plant Connector:Mixer name= CW DEMAND MIXER
** ~~~ ** Sum of Branch outlet mass flow rates= 0.000000 {kg/s}
** ~~~ ** Plant Connector:Splitter name= CW DEMAND SPLITTER
** ~~~ ** Splitter inlet mass flow rate= 3.248341E-002 {kg/s}
** ~~~ ** Difference in two mass flow rates= 3.248341E-002 {kg/s}
I’m sure the connections are ok. Does anyone have any idea what’s wrong?
Is this a sizing run failure? If so, check the design day schedules and sizing criteria.
