Anon questions the magic box

To be fair, the physics that makes refrigeration work does feel like you're manipulating primal forces like a wizard
- You are literally pumping hot outside.
  
  While utilizing the physics of pressurized coolants that prefer to be gasses around your house.
  
  And you can reverse the process, pumping heat inside instead, even when it's freezing outside! Magic, I tell you.
- Do not upset Maxwell's demon when you're down there sorting the cold atoms from the hot ones!
  
  Did Maxwell contribute to thermodynamics?
- Material phase changes are like a cheat code for humanity. Reusable chemical handwarmers are also black magic. You just click a metal plate inside and all of a sudden it's a hot solid.
  NightHawkInLight made a video showing how you can mix two different salts together and it'll create a packet that stays at 65 degrees for hours.
  Video in question
- Who needs magical thinking when you have thermodynamics?

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.
  
  Let's hope people won't get so reliant on LLMs and so uncritical they follow through
  
  I see no downsides
  
  Do LLMs ignore the /s even?
- This anti-swedish sentiment makes you look like a Dane.
  
  That's impossible. Everyone knows that Danes can't communicate.
- Weirdly this is basically how refrigerators worked before refrigeration was invented.
  
  But instead of throwing out the refrigerator, you'd just add more cold to it.

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
  
  Heat pump was one of the inventions I thought of in my childhood and was like "oh, it actually works and is good" as an adult.
  Of course, the child version was along the lines of "what if we take fridge, put the cold end out and hot end in", but you see the point.
- Seriously, that would have to work better than those giant fans they're building offshore.
  
  Ooh, I've always wondered what those were for. Makes sense.

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 ♫

The air is hot because it's moving around a bunch.
The air gets fanned over some coils filled with coolant.
The coolant gets heated and starts moving around a bunch causing it to move through the coil through some insulation foam to the outside half.
Once it nears the end of the loop it has to go through the compressor.
The compressor squishes the moving coolant and now it can't move around as much, all the heat gets dissipated into the surrounding outside air.
The compressor lets the cooled coolant go back through to the inside.
Process Repeats with diminishing returns.

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.
  
  No yah dummy. Put the Room in the middle of the Earth and PUMP all the outside heat into the planet core!
  BAM! Instant Arctic Weather in the middle of summer !
  And BAM! Reverse it for the winter!
  BAM! Mild Temps all Year round!
  You can thank me later EnvironMentaLists!

Ok, but here's a real answer. Have you ever sprayed a can of hair spray or wd-40 and the can got cold? That's basically the same process.
- Install a 12-pack of wd40 in my window, got it!
  
  Turn it upside down, first.

Shove the hot out the window. *taps head
- Literally how it works, too.
  
  Technology Connections has a great video that goes in more detail. Basically an AC is a reverse heater

Oh boy have i got a video you you anon!
https://youtu.be/7J52mDjZzto
It has an entire section at the start explaining how these magic cold boxes work to help with understanding their next evolution heatpump
- ofc it's a technology connection video. Lemmy is the dude's biggest organized fan club
  
  Based Lemmy users just understand how good it is. I can't wait for his third half hour video about dishwashers

ICP frequenting 4chan?

Wait until he finds out about refrigerators.

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.
  
  That efficiency metric doesn't really reflect what's going on. Of course moving stuff around is easier than heating it.
  
  Some are as high as 510% efficient
  
  The vapor compression cycle isn't exactly natural, and the compressor still needs a bunch of energy to keep going once it's started.
  
  Yup. I'm hoping my AC and furnace die around the same time so I can just replace both with a heat pump. Not sure if it'll save much on heating prices since both nat gas and electricity are pretty cheap in my area, but it can hopefully make maintenance simpler.
  
  Ah... energy doesn't work that way. You can't have a perpetually endless cycle with 100% efficiency in real world.
- Why would they remove heat any differently, it’s the same concept cooling a fridge or freezer as a room. Am I too ignorant to understand why this is crazy because I want my mind blown.
  
  How about saying that a normal air con unit, with a few extra valves, can heat as well as cool - in other words, if you've got Aircon, you've got a full heat pump, just without a pipe to do the heating bit. The energy you're spending cooling your house could also be heating your water... For free.

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)

"all of the sudden"
Disregard
- All of some sudden?
  
  Some of the sudden.*
- In ye ole Enlysch, it was
  “All of ye sudden”
  For some raisin, “all of the sudden” just tastes better to me.
  Technically “all of a sudden” is more correct.

Maxwell’s demon lives in there.
- It's like a mini-Gandalf telling all those Balrog-shaped hot molecules "YOU SHALL NOT PASS!".
  
  The demon lets the fast ones out and the slow ones in.

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

- Well I love AC Momma! And she loves me too! And she makes my titties real perky!

LOL 😅...so you got a cup of coffee ☕, you wait, it gets cold 🥶....how is that even possible?!!!

By boiling special magical water

Magnets!

  Maybe not far off.

You have to pay the bill so that makes sense

who has a window like that
- Americans. Wider belly needs wider windows.

Magnets

Its a placebo your room isn't actually cooling down. The power companies just want to charge you more money.

Physics, dog

Didn't Einstein work on some of the compression technology that went into refrigeration? Pretty sure he had something to do with it.
- Nope, not compression tech. The Einstein refrigerator is an absorption refrigerator and these don't use compressors.
