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
