AC dumps hot air _up_, not down.
- acdha 3y agoYes, we all learn that heat rises in grade school but it’s not an instantaneous or perfect process teleporting heat from the unit into the upper atmosphere. Most AC units are not on the roof of a tall building with nothing around - they’re in a window, car, on the ground, etc. and if you’ve ever walked in a city you can feel the difference it makes when you walk near or even under one. Even if more heat rises, a very noticeable amount diffuses into the surrounding environment and that encourages more people to turn theirs up, generating even more waste heat.
- KptMarchewa 3y ago>they’re in a window, car, on the ground, etc Car, sure. I live in a city in a country where window or ground units don't exist though. Most apartments are already way over ground, shops and other services mount the external units on the roofs. This is not an innate property of AC but a method US implements it.
