I’m talking about air conditioning. Why can’t we just use the ambient energy to move the excess energy out of the room somehow?
In: Engineering
In order to remove heat from a room, you have to have it absorbed by something, then that something release the heat outside of the room.
So what we do is use a gas that we compress (which takes a lot of energy) then run the air over the compressed gas while it’s being expanded, which absorbs the heat, then we pump the gas back outside of the room where it get’s re-compressed and sheds it’s head.
Ever take a can of canned air and hold it down for a while? the outside of the can gets icy. It’s kinda the same concept.
There is no way to use the heat to remove the heat. The heat in the room doesn’t contain enough energy to remove itself.
