There's a heatwave happening in the Europe right now. 18 people have already died in France. I was looking into air conditioners for a friend of mine who lives in the UK, and I saw a shockingly low number of actual air conditioners on sale, and a shockingly high number of "Evaporative Coolers" on offer. They're also sometimes called "Swamp Coolers".
DO NOT BUY THESE DEVICES.
These types of coolers work by blowing air over cold water or ice, and while they can produce a slight, localized cooling effect, they also increase the humidity in the air. At 40C (104F), a 40% humidity will feel like 48C (119F). 50% humidity will feel like 55C (131F).
Evaporative/Swamp Coolers only work if it is really dry. Like desert dry. And even then it's only effective up into the 90s (my personal opinion). Any higher and it doesn't do much.
