[Equest-users] Chiller Sequencing and Chiller Curves

[Jeremy McClanathan]

There is a custom chiller curve document written by Steve Gates that I found to be much easier to follow than the EDR guide.  You can download the document and an example spreadsheet from the following site:

The only tutorial I've seen that includes custom chiller curves is this one:

For the first question -
You can use equipment control to set the efficient chiller sequence as 1 and the other as 2, and prorate load as no.

HI All,

Two questions regarding chillers:


1.      Is it possible to establish a schedule to where one main chiller (a new efficient one) operates all the time and a second chiller (old energy hog one) only comes on line to cover peak conditions?

2.      Is there a good tutorial out there for inputting custom chiller part load data and  or curves?

Many thanks!
