[Equest-users] Chiller Sequencing and Chiller Curves

[Paul Diglio]

Jeremy:

When I click the link, at the bottom of the message it says :"You do not have 
the required permissions to view the files attached to this post."

Can you post the spreadsheet?

Thank you,

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!
