[TRNSYS-users] Type68 shading

[Stefan de Kool]

Dear all,

 

I have 2 horizontal windows, shaded by the same object, but from different
angles, so I use two Type68 shading masks (one with 6 and one with 7 azimuth
angles). I don't trust the results however because when I set one of the
obstructions to zeros (all betas = 0), the beam radiation is ok (equal to
solar radiation) but the diffuse radiation is less than the diffuse
radiation output from type16. As trnsys does not now the relative position
of the windows (as far as I can see), I do not see why this would happen.
Has anyone any suggestions? Below are the obstruction files I use (for
debugging I set one to all-zeros and the other to all 100, these are not the
actual values of the obstructions)
