[Equest-users] Title 24 2013 Baseline Chiller (Path A or B)

[Philip Kennedy]

Matthew it is highly recommended you obtain data for the actual proposed
chiller in order to receive the right answer. There is huge variability in
the unloading characteristics of different chiller technologies.

 

For example the chart below depicts two VFD chillers of equal capacity. The
solid line chiller is a single compressor VFD machine and the dotted line is
a three compressor magnetic bearing unit.

 

One curve DOES NOT fit all.

 

I suggest you reach out to the equipment vendors and have each of them
provide the necessary data runs. A help spreadsheet to aid the collection of
data can be found:

Greetings eQuest people,

 

I think I have a quick one for you that I could not find in the forums:

A chiller that has burned out is being replaced. The new baseline chiller is
the (CA Title 24 2013) 110.2-D chiller (path A or B). To calculate the
savings above T24 baseline, I first need to meet both the IPLV and kW/Ton
minimums for this baseline chiller. Does this theoretical minimum/baseline
chiller exist as a selection in eQuest somewhere? Is there a 'typical'
chiller (curve and efficiency) that can be downloaded/imported  and used for
this purpose that is industry accepted?

 

Any suggestions?


Thanks in advance,
