        While that is true in the sense that the lack of humidity allows for the evaporation to cool the air, a swampy running at peak efficiency cools the ambient air at best ~20°. If it’s 115, that’s still 95°. And that’s only if they are working perfectly, and they never are.

      They’re also called evaporator coolers. I am not sure if the word swamp refers to it performing a function that might be found around a swamp or how they operate.

      Maybe the pool of water at the bottom is referred to as a swamp.

      I linked the video but it’s been a while since I watched it. I am not sure if he explains the nomenclature.

        It’s because they smell like a swamp if you forget to clean them often enough. /S

          Why the \s? What makes you so sure that isn’t the real reason?

          If that isn’t the reason, then my guess would be that they’re called that because they increase the humidity of the room, making it feel like a swamp.

        A collection point for liquid drainage is called a “sump”.

        Examples: A basement may have a low point in the foundation with a drainage pump installed to prevent flooding: a sump pump. Boats have a sump to collect onboarded water called a bilge. They’ve a bilge pump to remove the water.

        Maybe “sump cooler” became “swamp cooler”?
