Post Rad Chiller Concept

The attached CP1-12730 curves can be used to tell pretty much what this TEC will do - there are similar curves for most commercial TEC units.

Unfortunately I am using ten TEC1-12709 elements. I can easily find graphs for TEC1-12708 and 12710 but not for mine. This caused me to look in more depth at the equations that are used to make the graphs. I prefer this to using graphs because its gives me more control and more accurate numbers.

You seem to know a fair deal about thermodynamics and peltiers so it still concerns me that you don't think you can get a peltier to move more heat that it consumes. I have seen it happen with my own test setup.

The only thing that I can think of, is that either you are used to using peltiers from a different perspective or that I've messed up somewhere. With all your examples you always seem to be using the peltiers at quite high towards their maximum voltage.

I and others have found that about 1/3 of the maximum voltage and below is where they really become useful. Have you ever used peltiers in this kind of range? If so, how did you feel they performed?
