It is possible that the hot water coil is leaking, and the cold air running mixing with hot damp air will cause the humid smell issue.

Why does your car car smell like antiseptic in a hospital when your ac is on?

This normally indicates a refrigerant leak. STOP USING YOUR AC IMMEDIATELY AFTER THE ACKNOWLEDGEMENT OF THIS SMELL!! The fumes from the fluid in your AC system are highly toxic. The leak needs to be sorted out before the AC can be used again.

When you shut up ac of your car water is getting drain this is ok or not?

If your ac is working well and is on in humid weather it will dehumidify the air and can drain quite a bit of water which you can see especially well when stopping the car it will drain underneath the car usually near the firewall in the desert when dry it might not drain at all but the more humid the more water, it can seem to just be pouring out!

Any smell from the car vents is unrelated to the AC system unless it is an antiseptic smell. Generally, the smells are environmental from your engine compartment, where the fresh air is taken from.
