I need too investigate an exist ducted air con system that is not conforming (cooling capacity insufecient)
the duct system is served by means of a chilled water AHU.
Any tips on where to start my investigation?
see attached scada image. please note that it was taken not on a hot day therfor the temperatures don't seem to high.
my concerns is:
-high delta T (10C) over coil
what is the recomended / typical supply air temperature (range) if the required room temperature is 23C?
