[TRNSYS-users] Heat exchanger UA value

[Martin Berov]

Dear TRNSYS users,

I'm trying to analyse the influence of the heat exchanger  area on the
solar fraction and collector efficiency.

I'm using storage tank Type 60c  with internal HX. Although I change the
area and the length(keeping the outside diameter constant) I always get
same results for the monthly solar fraction and efficiency - like there is
no influence.

What could be the reason for this?

Best regards
Martin
