[EnergyPlus_Support] A Question About FANCOIL:4PIPE

[Àî ×¼ <lizhun99@xxxxxxxxxxxx>]

Dear EnergyPlus Support Team:
   I am simulating a building using fancoil for air-conditioning and my 
IDF is just like the example file "FancoilAutosize".I want to know how 
the Fancoil:4pipe modulates the outside air flow rate. 
   How is the maximun outside air rate autosized?Is it just determined 
by ZONESIZING?Is the outside air flow aways set to the autosized 
maximun outside air flow rate? 
   I want to use outside air for free cooling when the outdoor 
temperature is lower than the zone air set point.Am I supposed to creat 
a CONTROLLER:OUTSIDE AIR for the fancoil out side air mixer?Wheather or 
not the FANCOIL;4PIPE  modulates the outside air flow in a complex way 
just like CONTROLLER:OUTSIDE AIR?
   Thanks for your help!
