Hello all,
It has been a while since I've posted on this board, but as I am a little confused on this topic I figured i would come here as a source of help.
I am overseeing the installation of air conditioning units in a hotel and am trying to define them according to ASHRAE 90.1-2010. ASHRAE defines two terms - PTAC and Room air conditoners. Both can be mounted in a wall, and both can supply both cooling and heating. However, when it comes down to minimum efficiency requirements, the numbers a quite different from each other.
Is the only difference between a PTAC and a wall-mounted Room Air Conditioner the fact that a PTAC comes with a wall sleeve? As I read the definitions, that is the only distinction I see.
Thank you for any help!
