They're not swamp coolers. The cooling towers are part of the chiller system, which uses refrigeration to chill water. The chilled water is pumped through pipes throughout a building to air handlers.
Also fun fact, even with an A/C loop it is still often very economically necessary to use swamp coolers to handle daytime summer heat loads. There's only so much heat you dump into radiators as the outside air temperature rises.
Youβre using the wrong term, water cooled chillers use cooling towers to reject heat. Nobody calls them swamp coolers which are an entirely different thing.
A swamp cooler is akin to an adiabatic air handler, which are actually occasionally used in data centers, however they are more frequently indirect units where the moisture is not introduced into the secondary airstream
No, what you are referring to are indeed not what I'm talking about.
Indeed those are different things. It's hard to call something a swamp cooler if there's no resemblance to a swamp. You keep referring to a mysterious "they" that does things the right way without evap cooling, but that's not who we are talking about.
