am modeling a data center which consists of 5 attached buildings. There is one
central chiller plant and all AHUs, CRACs are cooling only (w/ chilled water
coils).<o:p></o:p></SPAN></P>

plant has 4 centrifugal and 3 direct fired absorption chillers. I completed the
model with DD wizard. But I can’t define the base case chiller run logic into
the model. Building operators run absorption chillers during the summer peak
periods and doesn’t let more than two electric chillers to come online. They
don’t run the absorption chillers outside the summer months. e-Quest is running
absorption chillers all the time.<o:p></o:p></SPAN></P>
