How can I connect multiple «AirLoopHVAC:ZoneSplitters» in series in an AirflowNetwork?
Dear EnergyPlus-Community
I am currently working on an AirflowNetwork-Simulation for my master’s thesis. The target is to implement a mechanical ventilation system into am existing Multizone AirflowNetwork-Model. However, I am struggling while implementing the system the way it is built on site.
The original ventilation system contains a heat exchanger, followed by a supply fan and a heating coil. From here the air supply path will go onto a first «AirLoopHVAC:ZoneSplitter». From here multiple strings will lead to additional «AirLoopHVAC:ZoneSplitter»-Elements and from here the airflow will go into the various zones. Also, a return path which also goes through the heat exchanger and an exhaust fan is in place.
Unfortunately, I am not able to connect the ZoneSplitters to each other. Even though I checked multiple times. Also the AirLoopHVAC:SupplyPath is set up (as I think) correctly.
When connecting the ZoneSplitters directly to each other I will get the error message, that the Node used as Outlet/Inlet node for the Splitter is not defined as «AirflowNetwork:Distribution:Node»-element.
Hence when bringing a duct in between the two splitters and connecting this to the splitters I will get the error message that the Node or Component Name defined in in the «AirflowNetwork:Distribution:Node» is not found in the AirLoopHVAC, even though I have double checked that the «Component Name» in the AirflowNetowork Node is written correctly. Also, the error message states that the linkage is not valid for AirLoopNum assignment. For which I have no idea what this means.
So my principal question is: Is it possible to place two or more «AirLoopHVAC:ZoneSplitters» in series and if yes, how do I manage to put them in the right configuration? Am I missing an input field in another element I didn't mention?
Thank you for your much appreciated help!
