I consistently thought that air conditioning was a modern invention, however i just assumed that people simply went without any sort of cooled air up until about 100 years ago, and however, I recently found out that unusual aged peoples had their own forms of air conditioning, however take for example the aged Egyptians, they hung wet reeds in their windows to cool the air via evaporation. This is much love the swamp coolers that all of us use today; Before the Egyptians, people used to live in caves plus take fortune of geothermal cooling, then caves stay the same temperature year around. The two of us need temperature control to do that now. The Greeks used overheated or cool water to heat or cool their palaces. The two of us still use this technique in some homes that are heated or cooled with pipes that run under the floors The Chinese invented hand-powered fans. In the Middle East, they thought up air cooling techniques that used the natural air flow to cool their locales, and, the high ceilings of the Victorian Era were that way to keep the heat out of the buildings. The modern was entirely invented as a way to reduce humidity however it is safe to say that our new Heating, Ventilation, plus A/C systems utilize all of those things that our distant relatives knew plus used. It is self-explanatory to fall into the fallacy that only our generation has the brains to invent new things plus that only now can people live in comfort. This is wrong, people have been inventing ways to stay cool plus comfortable since as long as there were people on this earth.
