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.
so, magic.
Any sufficiently advanced technology is indistinguishable from magic.
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!
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
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
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.
So did engineers since decades. Just the fact that you get efficiency ratings of more than one in terms of primary energy input to heat energy provided should always have been a massive selling argument. If planned well you can get yearly averages of 400-500% energy output vs energy input.
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.
That efficiency metric doesn't really reflect what's going on. Of course moving stuff around is easier than heating it.
Shove the hot out the window. *taps head
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.
Wizard_Fucking_Magic
it adds heat to the system to make more cold. duh. global warming solved. stupid enviromentards.
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.
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
ofc it's a technology connection video. Lemmy is the dude's biggest organized fan club
Wait until he finds out about refrigerators.
ICP frequenting 4chan?
Maxwell’s demon lives in there.
It's like a mini-Gandalf telling all those Balrog-shaped hot molecules "YOU SHALL NOT PASS!".
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.
LOL 😅...so you got a cup of coffee ☕, you wait, it gets cold 🥶....how is that even possible?!!!
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.
