[TRNSYS-users] Type 109 vs type 15
Dear Trnsys-users,
For an analysis of Belgium weather data, I constructed weather files
using the Trnsys type 109 and 15 and the meteonorm file for Uccle,
Belgium. Making a summation of the resulting radiation on vertical
planes facing N, E, S and W, I notices big differences. The table below
indicates this :
T-drybulb I_tot_hor-1
I_tot_hor-2
I_tot_N
I_tot_E
I_tot_S
I_tot_W
Datareader 15-6 9,73 3416548 3416548 2302065 3075940 3625084 3081463
Datareader 109 9,73 3416548 3416296 1192961 2087489 2720244 2076203
Datareader 15-2 9,73 3416548 3416548 2302065 3075940 3625084 3081463
Difference 15vs109 -5,91E-05 0,088266 251,4136 1109105 988451
904839,9 1005260
0,00% 0,00% 0,01% 48,18% 32,13% 24,96% 32,62%
The two horizontal radiation values are : 1)directly provided by the
weather file and 2)processed using a plane with slope 0°
Am I doing something obvious wrong? Because the results are cearly too
different to be acceptable.
The dck files is included.
Many thanks,
Maarten Sourbron
