[TRNSYS-users] Angle Optimization in SDHW in TRNSYS - with Genopt

[Ramesh Rakesh]

Hello all,
I am trying to optimise the angle of collector for a Solar domestic hot water system (SDHW - example case) with the objective being to the Auxillary heat should be minimised. My idea is to assign the collector slope angle as a variable ("angle") and optimise it by varying it from 0 to 90 degrees in steps. The file writes the output into Daily.txt, Totals.txt and .pl2 files when you run it. In the current method that I have done, when I use genopt for the totals.txt file, the optimal angle for the whole year (8760 hours) is obtained. How do I approach it so that I can get the optimal angle at every time step (like hours 1 to 2 - angle is 35deg, hours 2 to 3 - angle is 38deg and so on)? Or if there is some method without Genopt, it would be nice to hear about it as well.

I use TRNSYS 17 and Genopt 3.0 and have attached the .tpf, .dck (both the input and the template file), .ini, Genopt commands related files as well. I would be grateful if you could help me out with this. Thank you.

Best Regards,
Rakesh
