Re: [TRNSYS-users] Concentration ration for Type 50e

[David BRADLEY <d.bradley@tess-inc.com>]

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

Dear sir,

I am using Type 50e (PV-THERMAL COLLECTORS - CONCENTRATING COLLECTORS - CONSTANT LOSSES - NO CELL OPERATING VOLTAGE) for simulating a Concentrating photovoltaic cooling system. I have a doubt that, How I can give (choose) a concentration ratio (Suns) for concentrator. Please guide me for the same.

Thanks & Regards,
