thats a sweet program u got there! how does it determin the temperature? just by the calculateion u gave it?

Its kryotherms simulation software, and its a very good when compared to real life. In reality the Rh and Rc values should be 0.2 for watercooling the tecs and 0.35 for air cooling, but the insulation is more like 100 if you use armaflex or alike.

Damn i get all confused by that program! :S

How did you get ths module running only on 7volts to pump 200watts (rated max pumped heat is 176, obvously) and still cool cold side well below ambient????
As far as I can tell this module is only able to pump 176watts at it's rated 24volts and hot side is going to be at ambient temp.
If heat source is stronger than this Tob is going to be higher than ambient....

I don't get it....

Theres 8 tecs in the system :p

But Jabo your still forgetting with a COP of > 1 your pumping more heat that your input power.

Cheers mate :)
Bloody expensive to use 8 modules...
Wouldn't it better to use like 2-3 226watt 15v ones runing at 5v?

COP ... hmmm. is it real? Can you really pump more themal energy than your electrical energy input is?

Imagine your module acting as Thermocouple scenario, right?

How would such COP value relate to this scenario?

A fan pumps way more heat than the input power. So why cant a tec ;)

8x172watt tecs dont cost as much as you think if you know where to buy them from ;) Even @ kryotherms retail price theyre only ~£138, can get them for ~$12 each if you know where to look though.

Them 220watt modules are pathetic compared to the entire kryothem range dT's are rubbish, COP's are rubbish.
