I have 6 downflow cracs that are being supplied with 45deg cw. I am seeing a varing delta T's across the coil averaging 12deg with one as high as 27deg. The total available name plate tonage is 140 Tons with an IT load of 150Kw. The cracs are all set with 67deg set point but the room has an ambient 76 deg. Based on available tonage and the electrical load I would have expected the room to be much closer to the set point.
I was wondering about the circuit setters on each crac because they are all wide open with one 10% closed, which is also the crac with the 27deg delta across the coil. Would slowing the cw flow across the coil allow me to get the space temp colder.
