Comment on The more air conditions in an area the hotter becomes around it. In turn increasing the demand for AC. Talk about infinite money glitch.

  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.

    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.

      Man's forgetting the second law of thermodynamics: The house entropy always wins.

      That’s legitimately how heat pumps work, except without decreasing entropy unfortunately

        Damn, I really thought we had it this time…

  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.

    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)

      100% efficient would mean they do their job without any waste heat. They create waste heat, therefore they are not 100% efficient.

      The only thing that is 100% efficient is an electric heater, because its job is to create heat, so it doesn’t create “waste heat”.

        A heat pump can heat a home by more than the energy in the electricity it uses. It’s more than 100% efficient at “converting electricity into heat in your home”. It does that by not actually covering electricity but by moving heat, and it is less than 100% efficient at converting electricity into motion, and introduces some waste heat

  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.

    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.

    You need some lessons in thermal dynamics my man.

    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.
