Hi
I am a new user of Grasshopper and Ironbug. I am currently carrying out building HVAC system simulations for typical cities in northern China. The system I aim to build features centralized hot water floor radiant heating in winter, and split-type air conditioners for space cooling in summer. I am trying to use Ironbug to customize this system, but I have run into problems during the setup process.
I have attached my GH file. Could you please help check what is wrong with the cooling coil water-side connection? Any hint would be greatly appreciated!.

From your description, you don’t need a chilled water loop in your system. It’s likely you didn’t build the radiant heating system correctly, and there are several discussions about the same error in the other posts. Please search for radiant floor, radiant ceiling, or radiant panel for the related discussions.
If you just want to run a quick simulation that represents a water heating system, I’d suggest you use a hot water baseboard system, which is much easier to set up.
Yes, I deleted the chilled water loop module. For the construction section, I added an Internal Source in the middle layer of the interior floor. The model now runs correctly without errors. Thank you very much.
