Invalid name with zone ASHP for DHW in a zone group

asked Dec 23

updated Dec 23

Hi everyone,

I am trying to model a zone ASHP DHW for zones that are also served by PTHP units in a multifamily building in Design Builder. The ASHPs from the zone group are connected to the supply side of the DHW loop. However, I am running into severe errors:

"Invalid component error" e.g. "Invalid Component Name input=LEVEL7X10:LEVEL7X10S1W WATER HEATER HEAT PUMP
**   ~~~   ** Component type=WATERHEATER:HEATPUMP:PUMPEDCONDENSER".

Has anyone ever faced this challenge? What could be the cause of these errors?

Although using DesignBuilder, that's an EnergyPlus-generated error. Can you double-check the spelling of the component and the other objects that reference it, specifically in the generated IDF file? See here and here for similar issues. Consider sharing the generated IDF.
