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!.
