[Equest-users] Chiller Staging

[Howe, Timothy]

Quick thought here.  Why not create a custom set of chiller curves which directly models your different stages and associated chiller efficiencies and model as one large chiller.

Subject: [Equest-users] Chiller Staging

Hello,

I have building with 6 chillers (2 different capacities) and I would like to model them with 14 stages of operation.  How can I independently control the increment (add chiller) and decrement (stop lag chiller) of an individual chiller stage. I was using equipment control, however, the saw tooth approach does not account for the overlap of plant stages. Thank you for your time.

Regards,
