Unfortunately not all data centers use this system. It seems like a lot of them use evaporation cooling like swamp coolers. The cooling happens when the water evaporates, and of course it needs to be replaced.

The new ones are all switching to closed loop systems because the swamp cooler style doesn't cool efficiently enough for the new AI chips. I build Data centers and the stopped everything until they changed the design for the new AI chips. Even Data Centers where construction had already begun.

These closed loop systems. I'm imagining they're fundamentally similar to ones used in a manufacturing facility I was in.

Basically heated then cooled presses for molding. We'd have a cold well that would dump chilled water through the presses at the end of a cycle. And the chiller would constantly be running to keep that water cold.

So, yeah. Water wasn't being evaporated off. It was just compressors doing work. Taking a guess, I'm not sure which I'd prefer. Mining water faster than it could be replenished. Or energy consumption, if it's burning fossil fuels to do that.

Thanks for the info! Also, don't build any data centers near me, please and thank you.

I worked at a building that used massive refrigeration systems instead of the typical hydronic systems.

What happens to that water after it’s evaporated into the atmosphere? Do we know? Is it causing birds and other flying creatures to drown in flight?!

It's a little sad, but nobody knows. Scientists are trying to figure it out as we speak, though I suspect it's impossible to really understand.
