Worse: it greatly increases humidity, which will make the stifling atmosphere, unless ventilation. A real air conditioner condensed water and recovered there, it's just the opposite.
An AIR uses a compressor and a refrigerant gas as a fridge. The exhaust air from an air conditioner is cold and the temperature of a room can drop several degrees.
It is therefore misleading to speak of air conditioner, it is not one. This is just a fan who plays.
This is MISLEADING see this article appear when you type 'air conditioner' as research.
