Ironbug airloop problem

Hi @MingboPeng, I’m pretty new in energy modelling, I’m trying to model a simple warehouse which use a air water heat pump to provide chilled/heated water to AHUs coils. When I try to export to OS, I came across the following error

Can you give me an hint on how to fix it? The gh definition is attached to the message.

Thank you

You are adding the same zone to both thermalzone and returnPlenum at same time. Please check all thermalzones and plenums to ensure they are correctly matched.

Hi @MingboPeng, I updated the definition as you told me, it seems to me that now thermal zones and return plenums are separated, but I still get the same error message. I attach the updated gh file so you can check if I did right what you told me.

@mich.dimart You are missing an “AirloopBranches” in UTA3. After added it to airloop, it can be exported without errors.

Hi @MingboPeng, thank you for your answer, now it works. I have a further question, how about to model an air source heat pump? how can I model it in Ironbug?

Thank you very much,
Michele

I have a further question, how about to model an air source heat pump? how can I model it in Ironbug?

Could you use Unitary system with DX coils?
Could you also please start a new post for this questions?
