[TRNSYS-users] Type 539 IAM

[Fred Betz]

All,

It's been a little while since I have modeled a solar thermal array.

Parameters 10 and 11 of Type 539 Flat Plate collector correspond to the opposite values on the SRCC sheets.

For example the IAM on the Vitosol 100 panel is -0.100(S) and -0.215(S) for the IAM equation (S)=1/cos(theta)-1

Therefore the IAM inputs for parameters 10 and 11 are: 0.1 and 0.215.

Please confirm.

Fred
