@DaLo Latest datacenter cooling requirements......

use outside air when there is a low enough temp as filtered OA in the 60F to 65F or below range. This is known as "Free Cooling". Since many servers can now operate well enough with 70F air temps, that's plenty of cooling.

The days of chilled water or DX cooling to 50F discharge air is over unless it's free cooling or small systems. Or you have to de-humidify it if it gets over 60% rH. They even have good luck with "Swamp Coolers" (Evaporative cooling) in dry climates like the Middle East too. (Unlikely to happen in Blighty though)
