[Equest-users] Data center CHW reset negative savings

[Sharad Kumar]

Hi Paul,

As per my understanding the thing required for the CHW set-point reset has
not been done successfully on your side.



As from the equest help the Fixed Control may send the same temperature of
cooling water for all the time.

The thing required for CHW reset should be OA-reset in which the data will
be as follows. Following kind of schedule has to be made.



The following case shows as an example how the CHW could be rest as per the
OA temperature. The same schedule ha been linked at the Reset-Schedule
required.



This process has been able to bring about few savings in the model by me.

Good morning all! I was advised to include our model files in case someone
could take a quick look at them and tell us the error of our ways. I would
still be happy to reimburse anyone for time spent! The problem we
encountered was we saw negative chiller savings from resetting the CHW. I
expect we made a mistake, but since the fans also have VFDs, it's possible
we increase fan energy while saving a little on the chiller, but it still
doesn't look right. Any help appreciated. Thank you eQuest users for the
help already provided!
