Re: [TRNSYS-users] Solar Radiation



Sascha,
  Type56 requires the total and beam radiation on each surface. It subtracts beam radiation from total internally to get the diffuse radiation.

Dear TRNSys Users,

 

i have a question about the solar radiation linked to the Type 56.

As input i have  e.g.

 

IT_S_0_90 … which i think is the „total radiation“ on the surface

and

IB_S_0_90… which i think is the „beam radiation“ on the surface

 

But as i know the „Total radiation“ is the sum of diffuse and beam radiation.

So when i link the total and the beam radiation to my surface i have the beam radiation twice because it`s already in the total radiation or am i wrong ? Maybe it will be calculated in the background ?!

There is no separate input to link the diffuse radiation to Type 56

 

Many thanks in advance

 

Sascha Heinze
