Thanks for the answers jbriggs444 and russ_watters!
One more theoretical question for you guys: would it be possible to design an AC unit that doesn't need to discharge warm air? My gut says the answer is no because such a system would cause a reduction in entropy, but I want to know what you...
I looked up the way a commercial AC unit works just before posting, and I know this method would not even come close to the current efficiency standard. I am more interested in the principle. Maybe I should have simply asked, would an expanding chamber cool the air inside it?
A similar...
The unit consists of a single, long rectangular chamber. On the inside is a moving wall. On one side of the wall is a vacuum, and the other side is room-temperature air. The moving wall starts much closer to the side with the air and moves slowly in the vacuum direction. As this happens, air...
