As a general rule, AC vents should point upward (but not enough to narrow the openings too much). This allows cold air to displace hot air before sinking. An exception is when the vents are located on the walls right below the ceiling. Here, vents must point parallel to the ceiling or slightly down.
The temperature difference between floor and ceiling can well exceed 10 degrees in an air conditioned room with 8′ ceiling heights, so it’s best to angle the vents upward in order to mix the room air to increase comfort level. Up or straight. Because hot air always will be on top due to its lower density than the cold air.
This means the air near the ceiling is the hottest, and the air near the ground is the coolest. If you point the vent upward, you will disturb the layer of hot air and cause it to mix with the cooler air to more evenly cool the room. Mixture is what you want.
In general, unless you need to vent odors or smoke outside, it’s best to keep the fresh air vent closed and recirculate the already-cooled air. To maximize cooling, don’t close the vents in unused rooms.
Which way are air vents supposed to face?

Should cold air return vents be up or down?

Why are AC vents pointed towards the windows?
They should point toward the rest of the room they are intended to help warm/cool. They can then be more precisely adjusted to provide the desired amount of airflow. Ceiling return vents should be oriented to minimize visibility.
Should vents be near windows?
HVAC air supply vents are under windows to counter cool air coming from the window. Cool air sinks because less active molecules are densely packed. The lighter, less dense, active molecules in warm air spread out and rise. As the warm and cold air mix, room temperatures become more comfortable.
Why are air vents above windows?
A trickle vent is a device usually fitted at the top of a window that allows fresh air to circulate naturally through a room, and allows polluted air out. They are controllable, to give the option of having them open or closed. When used correctly, trickle vents do not contribute excessively to heat loss.
