Re: [TRNSYS-users] weather data - zenith angle

[David Bradley <bradley@tess-inc.com>]

Charles,
  The zenith angle is calculated by both components. My recommendation would be to use Type15, particularly if you are are working in Trnsys17.
Best,

Dear all,

 

I would like to know whether the “zenith angle” is read in a TM2 file, or calculated by the weather data processors (types 109 and 15).

When I read the output “zenith angle” of a weather data processor, I find different values when using type 109 or type 15.

 

Thanks for your help

 

Regards,

 

Charles LAUNAY
