Starting from the OS template 'Packaged Rooftop VAV with Reheat', I tried to change the terminal for VAV NoReheat. I have no errors, but the is no heating in my zone.
To illustrate:
This case works fine (some Unmethours but no problem with the simulation):
But this case doesn't work:
I don't think there is any problem with the object 'AirTerminal:SingleDuct:VAV:NoReheat', as it works fine with other cases such as:
What I have tested: different setpoint manager, supply air temperature, variable or constant fan/terminal, hardsized some parameters... In all cases the result is the same : no heating !
For all my tests, the common point when the problem occurs is the presence of a 'Coil:Heating:Water' and a 'AirTerminal:SingleDuct:VAV:NoReheat'. So I think the problem is between the water and air loop. The E+ Output:DebuggingData also shows some strange behaviour. For example the node between the air terminal and the thermal zone in the air loop shows : 'Fluid Type: Water'. It seems it lacks heat exchanger (water to air) but I can't simply add a Fluid-toFluid HX in my air loop...
Someone has an idea to fix it ?
