Air conditioning can also be provided by a process called free cooling which uses pumps to circulate a coolant (typically water or a glycol mix) from a cold source, which in turn acts as a heat sink for the energy that is removed from the cooled space.
Some portable air conditioners have one hot air exhaust hose, and some have two air hoses: one for air intake and one for hot air exhaust. A single-hose portable air conditioner will take air from the room it's in, cool it, and return most of that air back into the room. Medium-Sized Spaces: Portable air conditioners in this category are best suited for cooling medium to large areas such as living rooms, sun rooms, or larger bedrooms. 2  If your room is between 350 and 700 square feet, view our available models with 11,000 to 14,000 BTUs of cooling power.
