The AC system is a closed system, and has no provision to drain the condensor. The system is under pressure and does actually have liquified freon in some portions of the system, while it is cooling the vehicle, it contains freon in differing states (liquid or gas).
I might be taking that fact a little too literally, I do do that sometimes. Unless it has a drain that I have never thought about.
I'll make some statements about AC systems, and these statements actually need some refinement, but it should give some information on the operation.
AC principle of operation is that if you pressurize a gas you can cause it to become a liquid, then if you depressurize that liquid (freon) it boils ( or changes back to its gasious state).
Then since it is a gas in a closed system, it seeks heat while in the evaporator to go along with that change of state, and if it is in a pressurized liquid state, it wants to be cooler, so it gives up its heat in the condensor.
The freon is as a liquid for the condensor in front of the radiator ( ie. suction side of the compressor ), so it can give up its heat that it collected while depressurized in the evaporator which is located in the heater housing/passenger compartment.
Believe it or not, propane is actually a better refrigerant then freon is, but for the obvious reasons of safety, it is not used.
In some commercial building there were vacume systems that actually use water as a refrigerant. With vacume systems there are problems with air being sucked into the system, so that is problematic as well.
All refrigeration and AC systems rely on that principal of operation. Then your engine cooling system works with just the opposite principle. You raise the boling point because you raise its pressure. Ideally your engine needs to run near the boiling point of water, and you don't want it to boil over, so you prevent boil over by raising the boiling temperature( by pressurizing the cooling system ).
The radiator has a drain plug next to it that, you ned a special tool to turn.
The condensor is between the bumper and the radiator.
