[Equest-users] Curve Fit

[Kevin Kyte]

OK, sounds great, so then INDEPENDENT-1 will be constant temp through all
data points or vary slightly with supply temp?  Something of such nature?

It looks like these curves are based on return and supply temperature.  I've
read in the DOE2.2 help file that the HIR-FT curve should be based on supply
temperature and boiler room ambient temperature.

Here are a couple that worked out for me.  Please check them for accuracy, I
have noticed some nice lovely savings with the curves.  We might as well
have an industry standard database where people can get schedules,
materials, part load curves, and many other inputs that are frequently used
in bldg-sim.  I think it may be nice to have a site to upload such knowledge
instead of every single person creating their own custom spreadsheets.  Food
for thought.

   TYPE             = BI-QUADRATIC-T

   INPUT-TYPE       = DATA

   INDEPENDENT-1    = ( 80, 80, 100, 100, 120, 120, 140, 140, 160 )

   INDEPENDENT-2    = ( 100, 120, 120, 140, 140, 160, 160, 180, 180 )

1.14,

has anyone figured this out?

 

Thanks,

Hello,

 

I somehow created this error message and don't know how to get rid of it,
can anyone help?

 

Curve Fit

    unknown/invalid component name

        &D was referenced on line 5228 but never defined

 

There is no error managing window, and this error appeared after I modified
the Heat Input ratio performance curve for a Boiler.

 

Thank you,
