Hi All,
I have a question regarding EnergyPlus HVAC system modeling:
How to model a 2 pipe FCU/UV in EnergyPlus because it seems to require that
I specify a cooling coil name which I don't have (I don't have a cooling
plant)?
Thanks!

Hi Qinpeng,
Cooling coil availability schedule can be used to make it unavailable.
From E+ IO Reference
Fan coil units can be 4-pipe or 2-pipe. For 4-pipe units there are 2
supply pipes and 2 return
pipes. For 2-pipe units there is a single supply pipe and a single
return pipe and the supply is
switched between hot and chilled water depending on the season. We model
4-pipe units, but
the 4-pipe model can be used to model 2-pipe units by using the coil
availability schedules to
make sure that either hot or chilled water is exclusively available.
Thanks,
Chandan
For a heating-only unit, you can use the unit heater or unit ventilator
instead of the fan coil.
