air conditioners GENERATE HEAT that's how they WORK

ok so basically what's happening in an AC unit, or a refrigerator, is something called the vapor-compression refrigeration cycle. in this system, a refrigerant transfers heat from one component to the next.
Compressor – The compressor squeezes the refrigerant and turns it into a hot, high-pressured gas that gets pumped into the condenser.
Condenser – The condenser is a long coiled tube. As the refrigerant moves through it, heat is dissipated into the environment. As it cools, it turns back into a liquid before being passed into the expansion valve. In a central AC, the condenser is located outside the house, so the heat stays outside. In a portable unit, the heat from the condenser coils is vented outdoors through the exhaust hose...

Expansion Valve – The expansion valve further lowers the pressure on the refrigerant, returning it to a liquid.
Evaporator – The evaporator is another long coil. Inside this coil, subjected to less pressure, the refrigerant begins to turn into a gas. As it evaporates, it pulls heat from the air to use as energy to power the transformation from liquid to gas. As the gas absorbs the heat, the *cold air* that is produced by the process is blown into the room by a fan.

It is EXTREMELY important to note that this process uses energy to MOVE heat from one area to another, it does not delete heat, and furthermore, this process takes energy, energy which itself, produces more heat.

We have no way to avoid this law of thermodynamics, you cannot get rid of energy.

*deleting heat is magic reversal of entropy* and no such technology exists or ever could exist. it's a perpetual motion machine, a faster than light drive, it's a fantasy technology. All refrigerators use energy to move heat, they don't get rid of it.

...and by using energy, they are increasing the overall heat of the system, accelerating entropy.

@starwall Hey, question. How rapidly does this break down if the pipe is cut or the fan is jammed?

@Pyretta instantly. it should be noted that typical refrigerants are dangerous chemicals and exposure to the air is generally associated with all kinds of environmental problems.

@Pyretta if you're looking to take out a refrigeration unit please don't cause an environmental issue, go for the power systems instead. snip wires not tubes.

@starwall Hmm, so jamming the fan is a better option. Sorry, looking towards antifa sabotage angles: expanding foam and stink bombs, wirecutters and wrenches.

@starwall Imagine massive corporate buildings *suddenly* having no AC on heatwave days and thus nowhere to hide from the heat. That's the kind of angle i'm driving at.

@starwall but i'm also looking towards making it as hard to fix as possible. Expenses on top of having to send everyone home? Yes please.

@Pyretta that would cause them to just cancel work on those days while they get new AC units but that's pretty good too

@Pyretta as a form of ecoterror, sure, but make sure you're not exposing refrigerant chemicals to the air and like, threatening our thin and precious ozone layer.

@starwall Cool, good to know. Leave the refrigerants alone, cut wires and fuck with fans instead.

@Pyretta also be careful when snipping live wires obviously wearing like rubber gloves and all that

@starwall Rubber gloves and insulated wirecutters (rubber handles) is about what i'd use.

@Pyretta @starwall be careful if you're looking at the condenser (outside unit); those things are usually three phase, which is standardised around 400V in most of the world but can be up to 480 in the us. you'll need more that rubber gloves and a pair of snips, doubly so since they almost always use armoured cable

@starwall so what you're saying is air conditioning causes global warming

@panamapauper but like, releasing heat into the atmosphere is a fine way to get rid of heat overall, the problem for the climate is greenhouse gasses keeping more and more of it trapped here instead of zooming off into space as infrared radiation.

@starwall @panamapauper the air conditioning wouldn't cause global warming if it wasnt powered by coal and other such fuels. solar powered anything has no foot print

@lyliawisteria @starwall @panamapauper thats true. that would at least leave a mark but if all of these processes were solar/wind/nuclear powered as they should be there wouldnt be a contribution to global warming

@lyliawisteria @NuclearTess @starwall
modern uranium mining doesn't generate tailings and besides that, if we reprocessed all the nuclear waste we currently just stockpile it'd last us a century anyway. I don't know what you're on about with the "radioactive dust" bit, and 'lobby' is an incredibly generous word to use about the nuclear industry's PR or lack thereof

@LexYeen @starwall was supposed to start at 7:45 (YEAAAAAAAHHHHHHHH!)

@starwall couldn't you, at the very least in theory, make a passive AC by using the right liquid and long enough tubes giving it time to cool off? the coils in the house would heat up if too hot and the vapor could be moved out side to a shady spot where they slowly cooled and the liquid flows back to the evaporating coil?

@starwall actually anyway that i look at this you would need at the very least a fan.

@NuclearTess if the outdoors were always cooler than the indoors this would work, but that's not the case. However, some geothermal cooling systems basically are exactly your idea, except instead of a shady spot outside it's a cool hunk of earth under your yard

@starwall oh thats really cool! i was thinking you just add a solar fan idea and it would work fine but this is completely passive thats even cooler

@NuclearTess I mean yeah it still requires power to pump around your coolant, and power to run fans to distribute the air throughout a building, but it is more "passive" than a refrigerant loop.

@starwall Is there a form of entropy that is not detrimental to the environment, that warmth can be transformed into?

@starwall this is the best explanation of how refrigerators work I've ever seen, thanks!

@AOL essentially, it's a medium taking heat from the air in order to become a gas. we then force it back into a liquid, and we run that liquid through a tube where it's allowed to radiate some of its heat into the air, and then the process repeats over and over. the only real component of the system is the compressor.

@starwall There's a company selling a condenser for a whole house AC which dumps the heat into water, the idea being that for someone who owns a pool, this will significantly lower their electric bill...

@micrackbiron @starwall
To look at the website it looks like snake-oil but the science is real. Cooler hot side => cooler cold side w/ less power to make it happen.

@micrackbiron @cjd actually yeah water is an AWESOME heat sink compared to air. that's why water usually feels colder (or hotter) compared to air of the same temperature, it is much more thermally conductive AND it can contain more heat energy over all.

@starwall @micrackbiron
aaaand evaporative cooling is why room temperature water feels so much colder than room temperature oil (it's a better conductor of heat too, but evaporation is what makes it colder)
