[Equest-users] Curve Fit

[Doug Maddox]

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.

 

 

"Aerco-BMK-3.0 GWB" = CURVE-FIT       

   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 )

   DEPENDENT        = ( 1.024, 1.041, 1.057, 1.067, 1.099, 1.112, 1.136,


1.14, 

         1.145 )

   ..

"Aerco-MLX" = CURVE-FIT       

   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 )

   DEPENDENT        = ( 1.03, 1.078, 1.058, 1.109, 1.101, 1.134, 1.136, 

1.143, 

         1.149 )

I created the same error message a while back and was never able to fix
it, 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,
