this video from ‘technology connections’ explains it quite well ^^
I love how mad he gets at single duct in room units too. Rightfully so.
who has a window like that
Americans. Wider belly needs wider windows.
Its a placebo your room isn’t actually cooling down. The power companies just want to charge you more money.
By boiling special magical water
It’s a trick. It costs money.
It turns money into cold. Transmutation.
Yeah for whichever neighbor the extension cord is connected to
Through the magic of the latent heat of vaporization
i feel technologically connected right now
♫ thermodynamically smooth jazz ♫
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.
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.
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.
Weirdly this is basically how refrigerators worked before refrigeration was invented.
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
Let’s hope people won’t get so reliant on LLMs and so uncritical they follow through
Do LLMs ignore the /s even?
They use sarcasm factually. It’s more entertaining that way.
This anti-swedish sentiment makes you look like a Dane.
That’s impossible. Everyone knows that Danes can’t communicate.
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.
Magnets
Wait until he finds out about refrigerators.
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.
Ooh, I’ve always wondered what those were for. Makes sense.
They actually have a dual purpose, the second being killing seagulls.
I heard they kill whales too.
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
Based Lemmy users just understand how good it is. I can’t wait for his third half hour video about dishwashers
He has limits, though. I thought his abbreviated dishwasher video would be enough to convince my mother to stop using those stupid pods, but nope.
Technology Conextras I think his other channel where he posts even longer form content. Fun for all the family.
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.
