Why is there humidity in the room when air conditioner is cooling? Room feels damp.
from the air in the vent to the air in the room
The air in an average sized room weighs about 100 pounds
Temperature of a room will goes up.Consider a room as a closed system. The only energy entering or leaving the room is from the AC unit. The AC unit cools some of the air inside the room by pumping refrigerant/coolant and heating up other air of the room (typically that exhaust air would be sent outside). Heat exhausted from the AC pumps increases the temperature of the room.
It depends on the BTU of the air coditioner, the cubic footage of space in the room to be cooled, and the temperature and humidity in the room. Under best conditions, an standard air conditioner can only cool a room to the mid 60's. Any colder than this causes the evaporator to ice over, clogging the air flow into the room, which causes the temperature to rise, even though the air conditioner is still running.
air fresheners can give a fresh scent to the entire room because vapor can diffuse into air.
Air does indeed take up room. Air molecules have a mass that takes up whatever room it is confined to.

the gas in the room freshener mixes with the air in the room and as air moves , the smell from the room freshener spreads through out the room
The mass of air in a room depends on how big the room is, the air pressure at the given moment, how pure the air (is it next to a coal-burning power plant?), what planet the room is on, etc.
A basic split air conditioner recirculates cool air in to the room.
The reason people use air conditioning is to cool a room by cooling the circulating air in that room
from the air in the vent to the air in the room
By bringing warm air outside the room
It is not possible to find your air around my book in your room.
N=60*fresh air/volume(room)
AHU - means "air handling unit" a big air cooling machine which supplies cooled air to the room via air ducts and supply air grilles and air diffusers
