Subject: [TRNSYS-users] length and witdh from the collector area

Hello TRNSYS-users,

I’m making simulations with plastic collector. Many from the commercial models can be resized, so it’s almost free how to configurate the collector area. I would like to find an optimal distribution, dependent of course on Radiation, temperatures etc…, basically how long and width for a minimum output temperature of the fluid. Or just what is the best for a certain situation 10m*30m or 30m*10m ?.

I ´ve already done my calculations with Excel and know that longer means higher output temperature but lower energy gain… but with trnsys it’s difficult to face the problem ,

do I take a standard unit and probe around different series und parallel distributions L ?

Do type 553 and 559 in TESS TRn17 do that; difference width and length (I didn’t find it in the general pdf… and have just occasionally access to TRNSYS17)?

Any advice or experience?

So Thanks a lot!!!!!

Mit freundlichen Grüßen

Fernando Sancho Márquez

Marc

If you still want to use g95, an alternative is to define T0, Tfinal and
Timestep as parameters in our new component. The only drawback is that you
have to be careful to change those values whenever you change them in the
simulation studio.

Danny and David,

I actually successfully used the G95 compiler with TRNSYS 16 to create
new components. However, i was not able to properly used TRNSYS
variables (such as getSimulationTime()) in my TYPES. The only solution
i found was to stop using this compiler and buying Intel Fortran v11.

I hope you will find a way to fix that problem as it is nice to have
the choice of a free/light fortran compiler.

Best,
