no doubt.

I remember when you’d put a jacket on before you went in the halls… but now everyone wears shorts.

10-15 degrees is all you need to keep a “cold aisle” at 85degf, most places, on the worst day.

IIRC Amazon figured out that individual components could actually run hotter within an acceptable replacement window.

higher equipment replacement is more than offset by the fact they don’t have to do refrigerant based cooling which makes daily operation ridiculously cheap… no pumps or complicated mechanical devices to produce cooling… no people with special skills to maintain them, etc.

critical data centers use swamp coolers because they don’t have to treat the water or expose it to contamination from outside. they use straight domestic water… super cheap.

if the conductivity gets too high, they dump the basin and fill with fresh… rinse and repeat.

a chiller is not a swamp cooler.

picture a fan with a wet sponge in front of it… that is a swamp cooler.

oh man! I just poked [email protected] for a Austria!=Australia flub in another thread… my come uppins!

yes. I programmed and integrated swap coolers at Amazon data centers. when the cool air hits the hot aisles the humidity goes down.

is liquid cooking cooling really necessary? critical data centers I have worked in use swamp coolers. cheaper, more efficient, more reliable, uses same water as your house…

edit: d’oh! :)

this looks similar to beets.

have you tried that? top notch, IMO. actively developed, awesome documentation.
