Delete MeInstructions to Requesting EngineerThis spreadsheet is
generic. It covers both new and existing chillers and constant and
variable flow condenser water scenarios. You will need to customize
it for your particular application by deleting or hiding extraneous
rows and worksheets.New Chiller Bids:For example, for a new chiller
bid to be evaluated with DOE-2 you should delete fields like Yr
Installed. You should also delete the Variable CW Flow worksheets
since DOE-2 can only evaluate constant CW flow scenarios.PG&E
CAP Chillers:For existing chillers in the CAP program you should
delete fields such as "Delivery Lead Time", "Fouling Factor" and
the Constant CW Flow worksheets. CAP chillers are evaluated using a
simulation tool developed by Mark Hydeman which has the ability to
model variable condenser water flows.Be sure to delete this
