Many people believe that air conditioners suck air from outside the room which causes concern that the air might carry impunities and allergens like pollen; the truth is air conditioners do not pull air from outside, they suck hot air from the room into the unit.

The wall mounted air conditioning units comprise of two elements – an internal and an external unit. The air from the room is drawn into the wall mounted air conditioning unit. It travels over the condenser and is cooled, thanks to the refrigerant; a cooling agent used in many refrigeration products. The cool air is then forced back into the room, which pushes the hot air and moisture out through the external unit.

The area which the wall mounted air conditioner will cover depends on the size of the room. The bigger the room the bigger the size of the air conditioner required measured in British thermal units (BTU).

On top of this, the ‘eye’ amazingly directs air away from people in the room to avoid anyone feeling a cold draft.
