Dear TRNSYS Community,
I would like to output the efficiency coefficients of a glazed solar collector under flow rates other than the tested flow rate. So, I tried to create a type based on Type 1, and include the calculated coefficients aa, bb, cc, and F_prime as outputs. However it throws this error: undefined reference to 'fprime_function'. How can I resolve this?
Also, I would like to know how this function corrects the coefficients of quadratic efficiency coefficients. The correction method in Duffie and Beckman's book is for the first order efficiency curve.
Thanks,
Shayan Davani
