Dear Trnsys users (or most probably
developpers)
Using weather data reader 109 for Tmy2 file, I am
getting confused in the way to connect it to the Mask Type 67 and the Building
Type 56.
For a given orientation in Type 56, I
need:
- The total radiation
- The beam radiation
(and other data which are not of
concern)
If this orientation is shaded, I have to get these
data from the type 67
I find, in the output list of type 67:
- The shaded total radiation
- The shaded beam radiation
Connecting the type 109 to type 67, I
find:
Outputs from 109:
- total radiation
- beam radiation
- sky diffuse radiation
- ground reflected diffuse radiation
Inputs to 67
- beam radiation
- diffuse radiation
Should I:
First solution: add the sky and diffuse radiation
from 109 and connect it to the diffuse radiation input of type 67, then connect
the shaded total radiation from 67 to the total radiation input of type 56
?
Second solution: connect the sky diffuse radiation
from 109 to the diffuse radiation input of 67 and add the ground diffuse
radiation from 109 and the shaded total radiation from 67 and connect the result
to the total radiation input of type 56 ?
Simply speaking: the beam radiation is not a
problem. What is unclear is if type 67 is dealing with the sky+ground diffuse
radiation or only with the sky diffuse radiation.
Thank you for your help
