[Equest-users] Multistack (DHRC) Dedicated Heat Recovery Chiller

[Aaron Derr]

Any idea why an .inp file would be empty?  I have a base project that I
started and did a “save as” to creaet a second copy to experiment with.
The .inp file for the original looks fine, but the file for the second
model is empty, even though the model runs and works just fine in eQUEST.

I have nothing to add to Byron’s very thorough response except that in
newer versions of eQUEST (I think versions 3.5 and above) you can select an
inp file as a parametric run.



Byron – great series of images. Would you mind sharing your inp file?

Aaron,



You will need to model it in the detailed mode, and use two models to
compare the savings rather than EEM or parametric runs.  You will need to
make sure the HW loop is set to operate at or below the Design-Cond-T
setting.  Normally there is a back up chiller that operates when there is
not a simultaneous heating and cooling load so you will need to create a
control scheme as well.  Some sample inputs are below

Can anyone guide me as to how to go about modeling a Multistack (DHRC)
Dedicated Heat Recovery Chiller in eQUEST as a proposed EEM?



Thank you,
