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
nawa@lemmy.world 9 months ago

ChickenLadyLovesLife@lemmy.world 9 months ago
Do LLMs ignore the /s even?

Weirdly this is basically how refrigerators worked before refrigeration was invented.
sugar_in_your_tea@sh.itjust.works 9 months ago
But instead of throwing out the refrigerator, you’d just add more cold to it.
Chivera@lemmy.world 9 months ago
Turn it around to cool the outside. Global warning solved.
Daefsdeda@sh.itjust.works 9 months ago
Actually a more efficient electric heater. This is known as an heat pump, aka reverse AC
Allero@lemmy.today 9 months ago
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.
ChickenLadyLovesLife@lemmy.world 9 months ago
Seriously, that would have to work better than those giant fans they’re building offshore.

Heat pumps really are amazing tech.
Honytawk@lemmy.zip 9 months ago
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.
Aux@lemmy.world 9 months ago
That efficiency metric doesn’t really reflect what’s going on. Of course moving stuff around is easier than heating it.
absentbird@lemm.ee 9 months ago
Some are as high as 500% efficient.
rbesfe@lemmy.ca 9 months ago
The vapor compression cycle isn’t exactly natural, and the compressor still needs a bunch of energy to keep going once it’s started.
And009@reddthat.com 9 months ago
Ah… energy doesn’t work that way. You can’t have a perpetually endless cycle with 100% efficiency in real world.
sugar_in_your_tea@sh.itjust.works 9 months ago
Yup. I’m hoping my AC and furnace die around the same time so I can just replace both with a heat pump.
Waraugh@lemmy.dbzer0.com 9 months ago
Why would they remove heat any differently, it’s the same concept cooking a fridge or freezer as a room. Am I too ignorant to understand why this is crazy because I want my mind blown.
LazerFX@sh.itjust.works 9 months ago
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.
FiniteBanjo@lemmy.today 9 months ago
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.

Technology Connections has a great video that goes in more detail. Basically an AC is a reverse heater
hyhachi@sh.itjust.works 9 months ago
it adds heat to the system to make more cold. duh. global warming solved. stupid enviromentards.
RecluseRamble@lemmy.dbzer0.com 9 months ago
So, if we all turned up the heat also during summer, the climate would cool down! Genius! Just don’t go inside.
maniii@lemmy.world 9 months ago
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!
Glowstick@lemmy.world 9 months ago
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.
RootBeerGuy@discuss.tchncs.de 9 months ago
Install a 12-pack of wd40 in my window, got it!

KillingTimeItself@lemmy.dbzer0.com 9 months ago
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)

Didn’t Einstein work on some of the compression technology that went into refrigeration? Pretty sure he had something to do with it.
user134450@feddit.org 9 months ago
Nope, not compression tech. The Einstein refrigerator is an absorption refrigerator and these don’t use compressors.

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.
