The three types of Portable Air Conditioners
Single Systems

Recognisable by the duct or exhaust hose which is used to expel the hot, humid air from the room being cooled to the outside. Single systems are ideal spot coolers. The condenser, compressor and evaporator are housed in a single unit.

The warm humid air is sucked into the air conditioner chilled, dehumidified and filtered and sent back into the room. The warm air by product is exhausted to the open air via the flexible hose. The moisture that is also a by product is exhausted in vapour form with the warm air or alternatively collected in a tank within the air conditioner.

Split Systems

Recognisable by the fact that there are two separate units linked together via an umbilical chord containing refrigeration pipes, cable and drain. The condenser (outdoor unit) and the evaporator (indoor unit). The condenser is placed outside and uses a fan to dispel the heat generated by the air conditioning process.

Evaporative coolers

When water changes from liquid form to vapour form, an endothermic reaction takes place. An endothermic reaction is when heat is drawn from its surroundings. Evaporative coolers work on a principle called “the sea breeze effect” or why you feel colder when you are wet. This is the principle on which evaporative cooling is based.

The unit is filled with water and panels manufactured of “easy-saturating” material soak up the water. A fan within the unit draws the air from the room across these panels and the temperature of the air is cooled and sent back into the room.

As such evaporative coolers are free standing i.e. no ducting is required.
