I was looking at the CentralChillerHeaterSystem_Simultaneous_Cooling_Heating.idf and CentralChillerHeaterSystem_Cooling_Heating.idf, however the CentralHeatPump only seemed to go to mode 1,2,3... not mode 4 or 5. Further, the inlet temperatures were quite high for the GHX, and the GHX energy transfer was only negative when I ran the simulations for a full year.
Does anyone have a file with CentralHeatPump working correctly, including going to modes 1,2,3,4,5, and also with normal ground loop (GHX) temperatures?
