Air cooled portable air conditioner units use ambient air and convert it to cool air with internal
condensers. These units require the use of air ducts to extract hot air from the unit and expel it
from the room, so an air cooled air conditioner requires a means of ventilation.
Typically, air cooled portable air conditioner units are ventilated through a window. It is also
common to extract hot air via a ‘floated’ ceiling where the hot air can be dispersed and not re-enter
the room. Other ways of ventilation include through doorways, into garages or into any room
which does not require cooling.
Large commercial grade air cooled portable air conditioners are often installed outdoors and utilize
duct work to bring cold air to and from, a desired location. These units are commonly installed as a
temporary measure to bypass a failed system, however can be used in virtually any application
where large quantities of conditioned air is required.
