Air Conditioners: Coolest Idea Ever

All humans want to be comfy, but the first air conditioner wasn't built for us--it was for a printing press!

Not a really big fan of this channel...








Just a large Air conditioner

[RJTheHero]

I always assumed AC units used the same mechanics as a Refrigerator. The only difference is you put it by the window and preserve humans instead of food. :3

[galamonkey]

As a Floridian, I really dont care what side effects the air conditioning has on the environment. I hate to be blunt, but if the thing ran on the blood of kittens and babies, Id be sitting here in the cold air crying about what I had to do to stay cool.

[Master_Therion]

I would rather die than live without AC.
"They may take our lives, but they'll never take our FREON!"

[SquareSquidStudios]

What?! You're telling me that air conditioners aren't cages for ice pixies enslaved against there will?!
Then why have I been putting food in my air conditioner!~

[JohannaHowes]

Dear Willis Carrier. You are my hero. Love Australia

[erictu]

I used to be a fan.... Now I'm an air conditioner, thanks scishow!

Let us thank the Carrier for inventing the thing that made life in this region less bad.

It's summer up here in the northern hemisphere, which means rain, rain and more rain if you live in Britain

[Scubadog_]

Meanwhile I'm sitting in 33 degree weather with no A/C.

Groaning at the ceiling has become one of my main pastimes.

Anyone from the UK will know that if the temperature rises above 20 degrees C(~68 degrees F), we complain that it's too hot.

[GoldenAircraft]

Cause you're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down

[xd_guy]

here in saudi arabia it's 40°-55° in the summer and people are drinking tea/coffe outside

[ohsosmooth]

So this is where the name Carrier originates from! Just started in the industry in a wholesaler.

[iammrbeat]

Aren't all decisions economic as long as scarcity is involved?

A few minor corrections:

1) We don't use HFC's anymore either, we now use HCFCs. Although we're supposed to be phasing those out soon too. It's still anyone's guess as to what will come next.
2) Heat Pumps still use refrigerants. The only different between an AC unit and a Heat Pump is that the refrigerant flow is reversible, so it can heat or cool your rooms as needed.
3) Water cooled heat pumps still use chemical refrigerants, but instead of dumping the heat outside it dumps it in a water flow which then can be transferred somewhere else (e.g. geothermal heat pumps being dumped into the ground).
4) Heat Pumps that use alternative refrigerants are theoretically possible (e.g. CO2 ) but the pressures needed to make it work are so high that they're very rare. CO2 is being used in some cases today but only in specific applications. You won't see them in your home anytime soon.
5) Ammonia is still used in large industrial applications and ice rinks.

Hey person scrolling through the comments section! Have a nice day!

[DummyAccount]

But why do I have air conditioning around my anus?! :-(

[MrFguy]

in sandblasting equipment we have to wear a helmet that supplies fresh air so we won't breath in the dust. On the back of the helmet, were the air hose connects to, there is a coiled tube. What the tube does, is that it uses centrifical force to 'sling' out the heat from the air before it enters the helmet. and it work very well.

[johnclavis]

a rapid-fire delivery combined with inadequate diagrams made it pretty difficult to follow what they were describing. or maybe I'm just drunk...
