Re: [EnergyPlus_Support] curve viewer



Dear James,

I'tried to fill in the 6 coefficients of the bi-quadratic curves of the "Default air-cooled chiller", but I couldn't see a curve.
Maybe I'm forgetting something ...?

I filled  C1..C6  in in the “Values in use for the chart display” table next to N1...N6.
I also filled in the Min and Max values for X and Y.

Do I have to fill in the Capacity ? (Doesn't change anything)

Best regards,

Geert

Dear Geert,

Visualization was a primary purpose of that spreadsheet, so I expect that you can display any standard curve!

I’ve attached an updated version of the sheet which is a bit cleaner in its organization. Without going into too much detail:

·         Find the “DISPLAY …. Curve” section of the spreadsheet which is appropriate for the specific curve type

·         Enter your specific coefficients in the  “Values in use for the chart display” table

·         Visualize

 

Let me know if there is something still not clear.

Jim,

I can be wrong, but is it possible to view the standard E+ chiller curves with your spreadsheet?
If not, is there a simple way to make them visible?


Best regards,

Geert Bellens

Geert,

There is a Curve Fit tool (I think it’s on the Help Desk site) for creating E+ chiller curves. 

I have a made a spreadsheet which helps visualization of various curves and combined the two tools into one spreadsheet.

The spreadsheet is intended for my own use, so you will need to do some exploration regarding how it works.  I hope it helps!

The different curves for chiller performance,often provided by energyplus or designbuilder, are they viewable with some kind of viewer ?
