To be fair, the physics that makes refrigeration work does feel like you're manipulating primal forces like a wizard
Do not upset Maxwell's demon when you're down there sorting the cold atoms from the hot ones!
Did Maxwell contribute to thermodynamics?
It's hard to believe that there was a point in my life where I could have read that article and understood it for the most part.
Now it might as well be hieroglyphics. Like I can see that symbol is an eye, and that one is a bird, but don't ask me what that shit means.
I'm with you. My undergraduate degree was in Physics 35 years ago and all I have left is vague impressions of very general concepts. I'm quite certain that I would be unable to do even the simplest derivative or integration at this point.
There's a tank of cold inside. Its the primary export of northern European countries and sustains nearly their entire economies since the only other thing they can "make" is fucking rotten fish. Its important to recycle your AC every 3 years before it runs out of cold by throwing it into the ocean where it can return to be made into glaciers.
Well, because you didn't add a /s to your comment, some day it will end up as an answer spewed out by some LLM, as absolutely factual.
I see no downsides
This anti-swedish sentiment makes you look like a Dane.
Weirdly this is basically how refrigerators worked before refrigeration was invented.
Turn it around to cool the outside. Global warning solved.
Actually a more efficient electric heater. This is known as an heat pump, aka reverse AC
Seriously, that would have to work better than those giant fans they're building offshore.
this video from 'technology connections' explains it quite well ^^
I love how mad he gets at single duct in room units too. Rightfully so.
Through the magic of the latent heat of vaporization
i feel technologically connected right now
♫ thermodynamically smooth jazz ♫
Heat pumps really are amazing tech. What if I tell you that this is also how your fridge works. Crazy, right?
They are also one of the few things that are more than 100% energy efficient.
300% to be exact. Because it uses some natural phenomena that just needs a little jump start and then can be maintained with little energy for massive air movement.
The vapor compression cycle isn't exactly natural, and the compressor still needs a bunch of energy to keep going once it's started.
Ah... energy doesn't work that way. You can't have a perpetually endless cycle with 100% efficiency in real world.
It's called a CoP, Coefficient of Performance. It essentially is a factor of how much electricity you put in and how much cooling power comes out.
Cooling towers can have a CoP of 12 and beyond, whereas compression cooling usually lingers at around 3 to 3.5. so at a CoP of 3 for instance, you could put in 1 kW of electricity and get 3 kW of cooling power.
Well it's not creating energy out of thin air. But it is moving it. So you get more energy moved than the amount of energy put in.
so technically, it's not generating electricity, it's moving heat from point A to point B, and believe it or not, 20f air still has a lot more heat energy in it than 0k air. So yeah, it's more than 100% efficient. Comparing it to electric resistive heating, which is producing the heat directly from electricity, rather than moving it around.
An electric resistive heater is 100% efficient, the efficiency of gas furnaces is measured similarly, though they hit about 90% eff, due to basic mechanics. Geothermal systems would also have greater than 100% efficiency as well, due to the fact that they just move fluid around, which is then cooled by the earth, (or warmed by it) though external heating wouldn't be.
it adds heat to the system to make more cold. duh. global warming solved. stupid enviromentards.
So, if we all turned up the heat also during summer, the climate would cool down! Genius! Just don't go inside.
Shove the hot out the window. *taps head
Oh boy have i got a video you you anon!
It has an entire section at the start explaining how these magic cold boxes work to help with understanding their next evolution heatpump
ICP frequenting 4chan?
Wait until he finds out about refrigerators.
LOL 😅...so you got a cup of coffee ☕, you wait, it gets cold 🥶....how is that even possible?!!!
phase change refrigerant loops baby!
Technically it's a uni directional heat pump. But we're just abusing the basic laws of thermodynamics. Fluids when compressed, heat up, and when expanded, cool down. Compress it, it heats up, cool it down, and then expand it, and suddenly, boom sub ambient cooling has been achieved. (the phase change happens in between to maximize effectiveness/efficiency)
Hot air goes out, cool air goes in. You can't explain that.
It's a trick. It costs money.
It turns money into cold. Transmutation.
Yeah for whichever neighbor the extension cord is connected to
Magnets
By boiling special magical water
You have to pay the bill so that makes sense
Its a placebo your room isn't actually cooling down. The power companies just want to charge you more money.
This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.
