Re: [EnergyPlus_Support] A Question about FAN COIL UNIT:4PIPE and COIL:water:cooling

["Michael J. Witte" <mjwitte@xxxxxxxx>]

I am not an expert on the coil model, but the model is explained in the 
Engineering Reference (p. 446, pdf p. 492).  This may be impacted by the 
particular sizing inputs used for the coil and the plant loop.
