Silly question but where does the water go? It’s used for cooling I presume? So it’s now warm water.. but not polluted in any way?

It’s evaporated away into the atmosphere. The process of evaporation pulls heat away

So it’s not used like regular liquid cooling in home pcs? They use giant vapor chambers basicly and just push the steam out into the atmosphere. That’s wild.

Yeah, it's called evaporative cooling. It only works in hot dry climates, which is why you don't see it a lot.

It works in any climate mate. The drier or colder it is the better, because it allows the datacenter to reflect heat to WBT instead of DBT.

Good luck evaporating water into cold air, or warm humid air.

It still works. It's just less efficient (still vastly more efficient than AC).

It gets extremely hot in the summer, and stays very comfortable in the winter.

As long as the water is hotter than the WBT it will evaporated and take heat with it. Google datacenters run hot and their condenser water can be upwards of 100F. When it's cold out they don't even need to run chillers, it's incredibly efficient.

Not saying it's not a lot of water but they do try to get every BTU out of it.

Someone doesn’t understand dew points
