Almost, What you are describing is the "dry" vapor/gas just to the high
energy side of a saturated vapor.
It is the point at which the temperature/pressure allows both a liquid
and gas to exist simultaneously (Think fog). The gas has absorbed enough
additional energy to change state but not temperature. This is a lot of
energy it is changing states that makes the AC work.
