[TRNSYS-users] Concentration ration for Type 50e

[David BRADLEY]

Sanjeev,
   There isn't really a "correct" answer to your question. It depends 
largely on the technology that you are trying to simulate. I would 
recommend that you refer to the Type50 documentation for the 
mathematical definition of the concentration ratio in Type50 and then 
choose an approximate value for your situation. You can of course test 
the simulation's sensitivity to the concentration ratio by running with 
a value that is somewhat below your initial estimate and one that is 
somewhat above your initial estimate. If you find that the results 
depend highly on the concentration ratio then you can spend additional 
time to choose a more accurate value.
kind regards,
  David
