Smart enough to understand heat pumps dumb enough to think it’s has that large of an effect.
The more air conditions in an area the hotter becomes around it. In turn increasing the demand for AC. Talk about infinite money glitch.

In cities it actually does have an effect, especially in crowded ones. Millions of people in a relatively small area blasting AC “exhaust” out of their windows heat up the crammed air and in turn the buildings, streets, etc. which increases the heat island effect of cities.
Granted, it’s not a huge effect, but it’s measurable. First source I could find: euronews.com/…/fact-check-is-air-conditioning-mak…

see I’ve been wondering if a heat pump system could heat an oven hot enough to bake bread. use environmental heat to manufacture Wonder Bread or something.
muntedcrocodile@lemm.ee 6 months ago
Huh guess so. But still 2.4 degrees ain’t a whole lot (well except on a global scale lol).

If only there were these things that grew out of the ground that cooled you home with their shade… What were they called again?
intensely_human@lemm.ee 6 months ago
If only people who lived in houses understood that not everyone lives in a house.
Scolding7300@lemmy.world 6 months ago
+1 although trees can shade the ground around the building and cool the area that way too
Croquette@sh.itjust.works 6 months ago
It is still highly beneficial in term of heat when there is a lot of shade in a city.
The tarmac gets really hot and release that heat for a long time.
buzz86us@lemmy.world 6 months ago
That is an urban planning problem

I remember a statistic claiming that at the peak of the Iraq war, the annually power consumption of US military ACs alone exceeded that of the African continent.
Knuschberkeks@feddit.de 6 months ago
turns out running AC to cool tents is super inefficient. Who could have known?
MNByChoice@midwest.social 6 months ago
Then heat pumps in winter will lower winter temperatures.
wabafee@lemmy.world 6 months ago
Who knew?
dcoe@lemmy.world 6 months ago
Nope. An AC just moves temperatures around. If it heats one area, it cools another.
pm_me_your_titties@lemmy.world 6 months ago
Except it is not 100% efficient. It will have losses, which will add extra heat to the surrounding area over what was removed from the target area. Thus contributing to the increase of entropy in the universe.
kakes@sh.itjust.works 6 months ago
The real trick is to reverse-cycle your AC, and pump the heat into your home. Because of math and algorithms, this one trick will decrease entropy and take us further away from the heat death.
wabafee@lemmy.world 6 months ago
🤣
hperrin@lemmy.world 6 months ago
ACs also generate heat as a waste product (they’re not 100% efficient), but I’m not sure that actually heats up the surrounding area to a noticeable degree.
Silentiea@lemmy.blahaj.zone 6 months ago
They’re more than 100% efficient (they move more watts of heat than they produce), but they’re less than ∞% efficient (they use Watts of energy still, so they still produce Watts of heat)
wabafee@lemmy.world 6 months ago
Yes your right should have been more clear. If AC moves hot air from a house. This goes out then imagine hundreds of AC doing that would that in turn heat up the area around it.
teegus@sh.itjust.works 6 months ago
As long as the temperature inside remains constant, as much cold leaks out as is transported inside. So the only residual heating outside would be from inefficiensies in the system, not the moving process itself.
Coreidan@lemmy.world 6 months ago
You need some lessons in thermal dynamics my man.
Thorry84@feddit.nl 6 months ago
To be extra clear: An AC transports the heat, not the hot air. It removes heat from the air and transfers that heat to the outside air.
There’s also heat pumps that work with water instead of air. So they remove heat from the air and push it into water. This water can be a closed loop, or be open where the water is lost. It can also work the other way around where the heat pump takes heat from outside and pumps it into water, heating up the water to then be used for heating a home or taking a shower. There are also water-water pumps that work on water on both ends.
Because heat pumps pump the actual thermal energy, the medium doesn’t really matter much.
Aurenkin@sh.itjust.works 6 months ago
It’s fine, just remember to open your window when you run your AC
Strobelt@lemmy.world 6 months ago
If everyone had ACs and did this we could revert global warming!

[deleted]Aurenkin@sh.itjust.works 6 months ago
You shouldn’t, it’s a terrible idea. I was just trying to make a joke implying opening the window will solve the problem by helping to cool the outside as well.
Alto@kbin.social 6 months ago
Already happens in a very round a bout tangential way. At least in America, most homes have far more heating capacity than they will ever actually use.
someguy3@lemmy.world 6 months ago
This doesn’t follow the meme or make any actual valid criticism. Furnace use doesn’t feed into itself. And furnaces kick on and off so sizing with a factor of safety doesn’t matter.
TrickDacy@lemmy.world 6 months ago
I don’t think that’s how anything works
bunkyprewster@startrek.website 6 months ago
It does and in two ways
-
running a refrigerator with an open door in a closed room makes the room warmer not cooler. The fridge just moves heat around but there is inefficiency too that comes out as excess hear
-
using energy to cool your personal space, increases global warming leading to a need for more air conditioning

I’ve thought about the same shit and that’s true lol

Global warming lockdown, let’s do it 🤣
tunetardis@lemmy.ca 6 months ago
That’s why we need passive daytime radiative cooling. In theory, it could completely eliminate the urban heat island, but it still seems to be mostly at the pilot project stage so far. I did read somewhere that you can DIY with some packaging tape (which somehow has the right properties?) over a reflective backing. Maybe I’ll experiment a bit this summer.
BastingChemina@slrpnk.net 6 months ago
There is a lot of passive system to prevent heat to come in, in the first place.
tunetardis@lemmy.ca 6 months ago
Yeah, I’m a big believer in shade trees! The one in our front yard has grown tall enough to provide blessed relief from a blazing afternoon sun. The only problem is the dude next door, who’s heavy into solar, is worried it’ll block his panels. And I’m a believer in solar too, so I don’t know what to say. Maybe we can come to some sort of compromise…
azertyfun@sh.itjust.works 6 months ago
what an understatement. it’s very unsexy but also incredibly effective. if your house is over 20 years old, you don’t need fancy-ass blinds, you need to get your house insulated ASAP. everything else must wait.
insulation is the number one most effective thing anyone can do to improve the energy use of their living space. only when your house is properly insulated can you think of shade management, greenery, passive ventilation, heat pumps, etc. in an insulated house, those either won’t work at all or will be wildly inefficient.
mojo_raisin@lemmy.world 6 months ago
You totally can.
I’m planning on making some panels to help cool my garden in an attempt to help plants survive extreme heat and sun by shooting some of that heat into space! The combination of partial shading with cooling mass vs heating mass should help a bit. People think it doesn’t work, but I’d imagine growing a garden on a asphalt blacktop vs white cement would make a few degrees difference. This technology does the same thing, it just pushes the boundaries further to cool below atmospheric temperature.
