Dear Kamel,

my pln-file is:  
...

# receiving       node  conncn sending          node  diversion  suppl1   suppl2
# component              type  component                ratio
  Col_1              1     3     pipe              1    0.500                 #  1
  Col_2              1     3     pipe              1    0.500                 #  2
  pump               1     3     Col_1             1    1.000                 #  3
  pump               1     3     Col_2             1    1.000                 #  4
  pipe               1     3     pump              1    1.000     60.0  0.0   #  5
  pump               1     3     pipe              1    1.000                 #  6

I have to change something, but I do not know what.

Thanks a lot.

Regards
Monika

Dear Monica,
 
The temperature of the collector is at the exit.
 
It sounds you're connecting the pipe to the two collectors with the proper diversity ratio, namely 0.5, to each of the collectors
 
The problem could be that the sum of the diversity ratios from each of the collectors to component donwstream of the collectors does not add up to 1

Dear all,
 
does anybody have worked with a solar collector? What does the resulttemperatur means for the component collector? Is it the temperature at the collector exit or is it the mean temperatur of the collector, or ...? 
 
I want to split the water flow from one WCH pipe to two flat plate solar collectors "segment". If I connect the pipe with both collectors and each collector gets a half of the water flow (diversion ration: 0.5) I get an error massage because the number of nodes is not correct. After the collectors I want to unite the flow in one pipe, but there is the same problem.
 
Dose anybody know how to split/unite the water flow? 

 Thank you very much.

Best regards

Monika
