Hey all I am a newbie to HVAC Engineering and i was working on a fan coil unit selection for a 2 pipe system and noticed that all major manufacturers talked about 3 and 4 coil rows coils , how do i know which i should choose. As both the 3 and 4 row provide the capacity needed. any help?

when you choose fan coil there is more to select than capacity.
Air distance throw,
Sound in db,
Air drying [air speed across the coil and No of fins per inch]
Unit size.

You have to be more specific when choosing a fan coil.
