I’m not 100% on how an A/C works, but I do know a basic concept of how adding energy will actually cool something. Every molecule will become a liquid at some temperature (EVERYTHING). For some molecules that temperature is VERY low, for example they use liquid methane to “burn” off warts as it has a very low liquid temp. So theoretically if you could condense a molecule into it’s liquid form, it would be very cold. So in essence I would think that if you could condense a molecule (in this case freon) into a liquid, and then run it thru a series of tubes in front of a fan, the air from the fan would become cold. However the energy needed to condense those molecules, would be rather significant. Hence you would have to put energy in, in order to get cold air. You should also keep in mind that it’s not only cold air coming out of your A/C. The side that faces outside actually pumps out quite a bit of hot air.
