Or does the sea water cooler some sort of air system?

Might as well be air system, there was a video made by discovery if I remember correctly on systems cooling whole already mentioned Australian Opera House.

Im guessing the sea water is quite cool, the probably save enoug to keep replacing parts. I still wonder how they keep corrosion down. Cool none the less.

Does Salt water have a higher heat capacity than fresh water?

My guess would be titanium or a thermoplastic (PVC or CPVC) on all the sea water parts, depending on the pressure and flow rate. The temperature is low enough that plastics will be fine.

Galvanizing isn't great in flow conditions, all it takes is a little flake or pit to form and you get crevice corrosion of the base metal.

Glass or ceramics are possible but an absolute nightmare to design and install - you have to use a lot of expansion joints and pay close attention to piping expansion and stress. They also generally end up more expensive than titanium.


Edit: We have been cooling power plants and other industrial sites with sea water for years. Ever wonder why they build a lot of power plants on the coast or the banks of large rivers?

Well, given that the average air temperature in Sweden is 6.6C (44F) and the warmest is 22C (72F) in July and -5C (23F) in January, liquid cooling only makes sense.

Now when you consider that currently the water temperature at Faro in the Baltic is 43F, and that the water temp ranges from 2C (34F) to a high of 23C (72F), and for the majority of the year the water temp is below 15C (59F), using a "water to water" heat transference system makes good sense.

i dont think it's even that intricate. I would bet salt/sea water doesnt even come close to the actual hardware. it's used to cool a heat exchanger that's connected to the servers.

Well yes, it even says so in the article:

But you have to get the sea water to the exchanger, and build the exchanger out of something.

Given that plastics are not too great at heat transfer that leaves a titanium heat exchanger, probably shell and tube type rather than plate and frame - slightly harder to clean but a lot more resistant to blockages.

The sea water tubing to and from the heat exchanger could be plastic or titanium, again it depends on the pressure and flow rate.

You got it.

It's not like running the ocean through your waterblock.

Edit: I think Vega (a hero to us all) does something similar with using groundwater to cool his stuff.

Indeed. They were able to cool several interconnected data centers all year round so even their warmest water temps are cold enough to get the job done. I wonder how warm the water is when it's exiting the last data center and whether or not it can be used for anything else (heating roads or homes?).

The water enters the first facility at 42.8 degrees Fahrenheit (6 degrees Celsius) and exits at 53.6 F (12 C). It's pumped to a second site, which it leaves at 64.4 F (18 C), and a third, which it leaves at 75.2 F (24 C). It's then sent to a heat pump and used to heat local homes and offices.
