They might say no, if you ask an older relative if they have heard about an evaporative cooler. But odds are they would understand the theory behind the technology. People could sleep outside on the screened-in porch to try and remain cool through the night, before air conditioning or other cooler kinds existed. They would often hold damp blankets over the displays in an attempt to cool the air. Because the heat passed through the page, it had been cooled. For other ways to look at this, consider looking at: water ionizers. And then your cool air could slowly circulate, relieving some of the heat for that sleepers.
Exactly the same concept exists today in the shape of evaporative coolers. These products are wonderful cooling systems for folks who live in warm, dry climates.

They are also identified by the name swamp coolers, but which can be misleading because they really won't work on all in swampy, humid conditions. The name probably originated from the way that evaporative coolers really add moisture to-the air. However in fact, evaporative coolers require dry, hot air to work because in order for the air to be cooled, it's to manage to get (escape) some of the water. Clicky is a cogent resource for further about how to see about it. When the air has already been saturated, it wont get any more water and it wont be cooled.
Heres how evaporative refrigerators work; the equipment is composed of a fan that draws the hot dry air within the cooler, where it's passed through moist parts. The parts are kept damp with a pump that circulates water through the equipment. As the dry air accumulates some of the water, its temperature drops, often by around 30 degrees Fahrenheit, depending on the environment. The cooler air is then taken into the room. An added bonus of an evaporative cooler is that the parts that cool the air also filter it. As the air passes through the pads, soil, dust, substances and othe
