Oooh. Physics AND biochemistry.
The cooling medium is the sweat on the surface of your skin. It is generated by passive osmosis of fluid following a concentration gradient created by a sodium ion pump driven by ATP proton donating molecules. This in turn derives energy from the breakdown of pyruvate molecules from the sugars in your food.
The cooling effect happens because of the enthalpy absorbing behaviour of the state change from a liquid to a gas as the fluid evaporates into a higher mollecular energy state. This effect is known as the latent heat of vapourisation. For water this is 2,260 kJ/kg (vapourising a litre of water will absorb that much energy). The dyson fan speeds up this effect by increasing the flow of lower humidity air passing over the skin:air interface.
The fan itself will not cool the room, it will actually heat it up by burning electricity. The room will feel cooler because your skin is a hugely effective air conditioning unit moving heat energy from your skin to the surrounding air (furtherheating the room). ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

Of course, we do it all wrong. We fling all the windows open and sit there cooking and complaining.
In a well insulated house during a heatwave you should keep the windows shut and the curtains drawn during the day then open them at night to let the hot air out.
Look at houses in the med, they shut them up tight and close the shutters during the day. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

I seem to remember reading that hanging a damp towel in front of the air helps with cooling air. Was always recommended as a way to keep the ferrets cool, so should work for peeps as well
Haven't needed to this year yet, but If it gets too hot try taking a cold, wet flannel to bed with you. I've fallen asleep with one on my face several times, lol. |

Get a fan with a water mister - they _really_ feel cool - I bought a little handheld rechargeable one, nicely effective:

Old Thread Alert!
