Thread-topic: Type 539 solar collector useful energy gain

I have a question about type 539 solar collector.

When I compare the output useful energy gain with my own calculation it doesen’t match.

Why is that and shouldn’t the useful energy gain be the same as my calculation?

I have used the following q=massflow*Cp*(Tout-Tin) to calculate the useful energy.

Best regards

Richard Thygesen
