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
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…?
No, since most cities are not fully air conditioned.
Infinite environmental destruction glitch
FTFY
If only there were these things that grew out of the ground that cooled you home with their shade… What were they called again?
If only people who lived in houses understood that not everyone lives in a house.
+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
That is an urban planning problem
Lamp posts? Radio towers?
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.
turns out running AC to cool tents is super inefficient. Who could have known?
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.
Nope. An AC just moves temperatures around. If it heats one area, it cools another.
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. And bringing us one step closer to the heat death.
🤣
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.
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.
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.
You need some lessons in thermal dynamics my man.
I don’t think that’s how anything works
