Re: [TRNSYS-users] solar radiation units of weather data type109

Dear Laia!
 
In the climatefile W/m² are/have to be used but the output of Type109 in the simulation studio is kJ/m²h (factor 3.6).
 
With kind regards,
    Matthias Kersken

Betreff: [TRNSYS-users] solar radiation units of weather data type109

hi everybody,

I am getting confused about the units of solar radiation (direct beam, etcc) when using type109: In mathematical reference , 5-432, it says in W/m2, but in studio type109 in out description says kJ/hm2.

what are the correct one?

thanks in advance
Laia
