[Equest-users] Scroll chiller curves in DOE-2 library

[Howe, Timothy]

Bill,

If you have the time, why don't you get the vendor rep send you over some data which you can make into curves?  See the attached docs if you have not already used/have them.

Steven Gates created the word doc and Jeremy McClanathan the excel spreadsheet.

I would not trust those curves unless someone on the eQUEST development team can validate them.

Tim.

Subject: [Equest-users] Scroll chiller curves in DOE-2 library

I am modeling a new air-cooled scroll chiller, but eQUEST doesn't have a "scroll" chiller type. I'm guessing the "screw" chiller type is the closest option. Out of curiosity, I searched the library and found the following performance curves:
ScrollChlrAirCoolEIR-fPLR
ScrollChlrAirCoolEIR-fCHW&OAT
ScrollChlrAirCoolCap-fCHW&OAT

Using these curves greatly reduced (by 33%) the cooling energy vs. the default ScrewAir-EIR and ScrewAir-Cap curves. Did I find the eQUEST version of a video game cheat code? (Any reason I shouldn't use these ScrollChlr curves?)

Thanks,
Bill
