We have a 20hp glycol chiller that is 2 10hp units working in tandem (when necessary).
We have been running the sytem with both units set to chill to 25*. One unit will be set to turn on if glycol temp reaches 26 and the other is set to kick in when it reaches 27.
Do you think I should make the differential between the 2 larger than a single degree? Am I at risk of short cycles on the unit currently set as the secondary?
The system has been working fine as is, but it was time for me to switch which is the primary and secondary units to balance wear and it got me to thinking about this...
Thanks,
Brian
