[EnergyPlus_Support] Generating input for SOLAR COLLECTOR PARAMETERS:FLAT PLATE
Hella all,
I am interested in simulating the performance of solar panels
distributed by a German manufacturer (Vitosol).
I do have catalog data from the distributer. The catalog stipulates
that..
___________________________________________________________________
"The thermal loss coefficient and optical efficiency combine to form
the collector efficiency curve which can be calculated on the basis
of the following formula:
n = n0 - k1 . (dt/Eg) - k2 . (dt^2/Eg)."
_____________________________________________________________________
However, E+'s idf requires:
(a) Test Fluid
(b) Test Volumetric Flow Rate {m3/s}
(c) Test Correlation Type
(d) Coefficient 1 of Efficiency Equation (Y-Intercept)
{dimensionless}
(e) Coefficient 2 of Efficiency Equation (1st Order) {W/m2-K}
(f) Coefficient 3 of Efficiency Equation (2nd Order) {W/m2-K2}
(g) Coefficient 2 of Incident Angle Modifier (1st Order)
(h) Coefficient 3 of Incident Angle Modifier (2nd Order)
As a result, I am unsure of the values I should instantiate in my
input file. I would appear to have direct input for (d) only as the
solar circuits have a mixture of glycol in order to provide frost
protection.
Does anyone have advice from previous experiences?
Kind regards
-Elmer
