What would make a better water chiller given the same qMax ability of the tec's... more of the lower rated tec's to create a large surface area... or a lesser number of higher rated tec's creating a smaller surface area?

Not sure if that is very clear... the combined qMax of the two different tec combinations would be the same. One of the combinations would have a larger surface area than the other. Both combinations would use the same amount of current.

Or to put it another way... If you have a fixed amount of current to work with would it make any difference if you use the current to make a water chiller with a large surface area or a smaller surface area?

Sorry... I am not asking this very well.

Bottom line... I would like to know the best combination of tecs to make a water chiller that will be powered by 70-90 amps.

Thanks in advance
