Hallo Max,

 

you can find quite recent (up to 2005) collector test data on the web site of ITW (University of Stuttgart), which is one of the largest test centers for solar thermal collectors in Germany:

http://www.itw.uni-stuttgart.de/ITWHomepage/TZS/Berichte.html

In the test protocols you have to look for "Anhang A" to find information about the transversal and longitudinal incidence angle modifiers.

 

Best regards,

Mathieu

Betreff: [TRNSYS-users] Type 71

Dear TRNSYS Users,

I have a little problem with Type 71, and the necessary external data file. I think I more or less understood how to creat the external data file, but I do not know where to get the data (hence the traversal and logitudinal modifier values) from. If i understood well these values are provided for diffrent types of collector respectivly. Since i am onlz simulating, i would like to now where to get the data necessary from??

Thanks

max
