Hi ALL, I have obtained the cooling load of my building (based on
QCOOL and QLATD) using idealized cooling in TRNBuild. I have also sized my
chiller to meet the peak load of my model. I am intending to use a single
chiller to meet my model’s cooling demand. My model consists of 8 zones and the peak load is based on
the summation of the cooling loads from these 8 zones. I have also created inputs (i.e. RH, Temp, M_dot) to allow
my model to accept the external cooling device, which is a water chiller
system. I am setting the ventilation of all 8 zones to these inputs (i.e. only
one ventilation type). My query is: By using a single chiller sized at peak load and setting
each zone to accept the chiller system, would I be oversizing my chiller? Since
I believe each zone’s load is only a fraction of the peak load and my
ventilation type only targets one zone instead of all zones together. Or, should I be using a chiller for each of my 8 zones (i.e.
altogether 8 chillers) and sized them to the respective peak loads of the
zones? PS: My model requires a central core in the middle of the
room, so in order to have the central core, I created 8 zones around it using
the Multizone building. I hope I am clear with my description. Any help is deeply appreciated. Nguan Teck NTU, Singapore Final Year Undergrad |
