To be fair, the physics that makes refrigeration work does feel like youâre manipulating primal forces like a wizard
While utilizing the physics of pressurized coolants that prefer to be gasses around your house.
Do not upset Maxwellâs demon when youâre down there sorting the cold atoms from the hot ones!
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 itâs a hot solid.
NightHawkInLight made a video showing how you can mix two different salts together and itâll create a packet that stays at 65 degrees for hours.
Thereâs 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 âmakeâ 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 didnât add a /s to your comment, some day it will end up as an answer spewed out by some LLM, as absolutely factual.
Thatâs impossible. Everyone knows that Danes canât communicate.
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 âoh, it actually works and is goodâ as an adult.
Of course, the child version was along the lines of âwhat if we take fridge, put the cold end out and hot end inâ, 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 theyâre building offshore.
this video from âtechnology connectionsâ explains it quite well ^^
Through the magic of the latent heat of vaporization
