[TRNSYS-users] Type 1245 Problem in the number of series and parallel flows

[David BRADLEY]

Zhao,

   The input file is related in this case because that is where the 
parameter value of 101 (the value that the component does not accept) is 
written. The source code is not set up to allow more than 100 collectors 
in series. In order to modify that limitation you would need to have 
access to a Fortran compiler and to recompile the Type with a higher limit.

   As a side note, a collector's efficiency is inversely related to its 
inlet temperature. The higher the inlet temperature the lower the 
efficiency. I think that with so many collectors in series, the 
efficiency of the collectors near the end is going to be very close to 
zero and therefore you won't get much of a temperature rise out of them 
anyway. I would highly recommend putting your collectors in parallel 
instead.

kind regards,

  David
