Question about Emerson Quiet Kool 12NW46K Air Conditioner
No - opening the vent will allow unconditioned outside air into the space and add to the humidity load.
Think of it like your car's A/C - when you put the controls to "Max A/C" the system recycles just the air inside the car and doesn't use any outside air. When the control is set to normal A/C, some outside (fresh) air is brought in.
The same thing is true for a window A/C unit. Keeping the vent closed will help the unit de-humidify and cool the air more quickly.
