Hi all,
I'm trying to model a chilled ceiling with a VAV air supply for ventilation and additional load pick-up when needed. Has anybody tried to do this before? I'm running into problems because the IU and FCU systems all have CV fans (therefore fan energy is overestimated and the model shows negative savings over the baseline). I also looked at the PIU system (because you can select a variable speed fan), but I don't think this is appropriate because it appears that the cooling coil is in the AHU. Anybody have any tips or run into this before?
