HVAC Geothermal Heat Pump with Floor Radiant ASHRAE 90.1

[AntonelloDiNunzio]

Hi @MingboPeng,

I had a test.

1. I have set a simple box with all adiabatic surfaces, space type “Office::OpenOffice”.
2. I have added a probe to check supply exit node.
   
   
3. I have added a switcher to change supply type: Geothermal Heat Pump or District Heating cooling.
   
   

GSHP Results:

1. Series of warning because inner air temperature is extreme.
   
   
2. Probe results:
   
   

District Heating/Cooling results:

1. Series of warning because inner air temperature is extreme.
   
   
2. Probe results:
   
   

Other tests:

1. Plenum zone test:
   
   
2. Packaged VAV with reheat
   
   

At this point, I am pretty sure there are some errors in how I have modeled plant loops and setpoint.
Could you take a look at this new file and give me a feedback about results above?
