RE: [EnergyPlus_Support] Fatal Error: HotWaterSystem





I believe that when the simulation starts, and created the IDF expanded, there is a conflict between these branchs.

I do not know how to solve this. Only used the HVAC templates. Maybe you can not use this due to the conflict.

Has anyone seen this problem?

Thank you Jim.

Ivan,

I think that I would first focus on the highlighted portion below

Sorry, i forget this.

 

The fatal error is:

 

** Severe  ** GetFirstBranchInletNodeName: BranchList="BOILER_PUMP HW DEMAND SIDE BRANCHES", Branch="BOILER_PUMP HW DEMAND INLET BRANCH" not a valid Branch Name

   ** Severe  ** GetPlant/CondenserLoopData: PlantLoop="BOILER_PUMP HOT WATER LOOP", Invalid condition.

   **   ~~~   ** The inlet node of the first branch in the Demand Side Branch List Name=BOILER_PUMP HW DEMAND SIDE BRANCHES

   **   ~~~   ** is not the same as the Demand Side Inlet Node Name=BOILER_PUMP HW DEMAND INLET

   ** Severe  ** GetFirstBranchInletNodeName: BranchList="BOILER_PUMP HW DEMAND SIDE BRANCHES", Branch="BOILER_PUMP HW DEMAND INLET BRANCH" not a valid Branch Name

   **   ~~~   ** Branch List Inlet Node Name=Invalid Node Name

   **   ~~~   ** Branches in a BRANCH LIST must be listed in flow order: inlet branch, then parallel branches, then outlet branch.

   **  Fatal  ** GetPlant/CondenserLoopData: Errors found in processing input. Preceding conditions cause termination.

   ...Summary of Errors that led to program termination:

   ..... Reference severe error count=5

   ..... Last severe error=GetFirstBranchInletNodeName: BranchList="BOILER_PUMP HW DEMAND SIDE BRANCHES", Branch="BOILER_PUMP HW DEMAND INLET BRANCH" not a valid Branch Name

   ************* Warning:  Node connection errors not checked - most system input has not been read (see previous warning).

   ************* Fatal error -- final processing.  Program exited before simulations began.  See previous error messages.

 

 

I don't know why. Thanks for your helpness.

You don't say what the fatal error is.

when i use HVAC Template: ChilledWaterLoop and HVAC Template: HotWaterLoop appears one fatal error.

I need to simulate a chilled water system and a heating system to gas, but when I insert the heating system it gives me this fatal error.
