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.
Nope. An AC just moves temperatures around. If it heats one area, it cools another.
Yes your right should have been more clear. If AC moves hot air from a house. This hot air goes out then imagine hundreds of AC doing that. Would that in turn heat up the area around it.
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.
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.
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.
Then heat pumps in winter will lower winter temperatures.
Who knew!
Unfortunately it does not work that way :(
Whoosh
Ah, I was afraid that might happen. Oh well.
I’ve thought about the same shit and that’s true lol
Covid lockdown was the best days with climate Hope everyone will understand what’s causing global warmingGlobal warming lockdown, let’s do it 🤣
Smart enough to understand heat pumps dumb enough to think it’s has that large of an effect.
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: https://www.euronews.com/green/2023/08/30/fact-check-is-air-conditioning-making-cities-hotter
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.
I don’t see why it shouldn’t be able to. You might need concentric shells depending on the power of the heat pump.
I don’t see either but I know you can’t. Otherwise we would have an infinite energy glitch
I don’t see how? Using heat pumps to concentrate heat doesn’t seem like a violation of any thermodynamic laws?
Heat pumps are 500% efficient. Put a steam engine at the end, efficient at 30%. You just got free energy
They don’t continue to be 500% efficient as you fill their downstream side with heat.
Huh guess so. But still 2.4 degrees ain’t a whole lot (well except on a global scale lol). Thankfully in this situation doesnt really cause additional global warming problems.
Cities are already about 5C hotter than the surrounding countryside. Adding this increase on top, means 7.5C.
4OC in the countryside is already bad, 47,5C in the city is deadly for a lot of people.
I think you underestimate, how deadly heat can be: https://en.m.wikipedia.org/wiki/Wet-bulb_temperature
Wouldn’t those 2.5C already be included in cities being 5c warmer…?
I don’t think that’s how anything works
If only there were these things that grew out of the ground that cooled you home with their shade… What were they called again?
Gazebo!
Lamp posts? Radio towers?
If only people who lived in houses understood that not everyone lives in a house.
That is an urban planning problem
+1 although trees can shade the ground around the building and cool the area that way too
they also convert some of the sunlight turning air into sugar instead of getting warmer
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.
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.
There is a lot of passive system to prevent heat to come in, in the first place.
- Brise soleil (sun-breaker) - these systems prevent direct sun to go through the window in summer, but let it in to heat up the habitation in winter.

- Trees ! - Trees have a cooling effect in summer and a keep the warmth in winter. They also improve air quality, physical and mental health. Increasing the areas covered by trees in city could bring down there temperature by several degrees.
- proper thermal insulation.
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…
proper thermal insulation
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.
I’ve added it at the end because it seemed obvious to me but yeah, insulation is the first thing to do. Especially under the roof.
Infinite environmental destruction glitch
FTFY
It’s fine, just remember to open your window when you run your AC
If everyone had ACs and did this we could revert global warming!
