Goodmornig. I'm trying to simulate an hydronic system with high temp radiators with Openstudio but I'm having some problems. I'll explain what I've done:

  • the building has a single thermal zone and several spaces;
  • I create an empty plant loop where I define a "gas boiler", a "HW Htg Coil", "Varibale speed pump" and a temperature manager. I connected the "HW Htg Coil" with the following air loop
  • I create an empty air loop where I define a "HW Htg Coil" and I connect the loop with the sigle thermal zone.
  • In the "zone equipment" I insert a high temp radiant

When I launch the simulation the system returns me a Fatal error "AirLoopHVAC="..." is not connected to any zone". In the sheet Thermal Zones the Air Loop Name report the name of the air loop I inserted.

I'm definitely forgetting a step but I can't find where.

Thanks to anyone who can help me

Per the error, the thermal zone isn't connected to the air loop. See the OpenStudio tutorial for how to connect thermal zones to air loops:
