[Equest-users] DOE 2 Manuals

[Nick Caton]

Thanks Dan!

Scrolling further down that page than I have before, following the links to each volume, I've found my answer:

"These documents are the basis of the eQUEST on-line help system but contain a more complete and up-to-date description of the details of the DOE-2.2 version within the current release of eQUEST."

Better keep these PDF's handy as well!

Highly recommended for anyone using eQuest - the manuals behind the DOE-2 engine:  http://doe2.com/DOE2/

I am constantly referring to these every time I get stuck and need to know how something in eQuest works.

Cheers,
Dan

I suppose you could set those to be constant. Another way would be to just take the Cooling Load from the SS-D report and divide that by your constant COP.  But my question would be, why do you want to do that ?
