Define "Water Chiller"

[Tecumseh]

You might not have to worry about condensation if you
are above the dew point. Read this thread.

Napoleon, in order for your waterchiller to work, you need to use two loops? 2 pumps, 2 rads etc...

Thats setup you have. Does it run?

Loop 1 -Pump, cpu, heater-core, chiller, Pump

Loop 2 -Pump, heater-core

also

Do TEC chillers consume more watts on average then units using refrigeration units like the prom. ?

These pics show part which connects 2 fluid circuits - so basically there's a need for 2 pumps. On cold CPU side, you don't mount any rads as water chillers is a part which cools it.

TEC chillers use a LOT of power, far more than phase-change units as Prommy. As avarage, you may assume that efficiency of TECS is 8-9x worse than phase change, so basically to get efficiency of 200Watt phase-change cooling, you'd need 1.6-18.kWatt Pelt array (lol).

How did you arrive at that figure?

A factor of three would be more accurate. My TEC chiller, which is pelted to 300 Watts can keep a workstation comfortably cool.

Phase change is more efficient, as you can use a factor of ~1/3 (hence 9 times better).

Here is a frige style chill I set up several years ago. I never finished the system but still have the frige. It would keep my 1333 axia@1650 with 2.2vcore around 15c with a 25c ambient temp.

Officially TECs have efficiency of around 5%, while phase change 40-45%. These are numbers just numbers
So basically good 35Watt phase change could do hte same, but there's something like minimal power due to pressure difference you have to achieve, so it's not so easy to have <100Watt phase change. That might be why we don't see so much advantagg of phase change over TECs. Other thing is that TECs are just easier to havethan phase change
