There are 4 principle types of portable Air Conditioners, these are:

1. Evaporative coolers
2. Exhaust tube units
3. Split type units (refrigerant)
4. Split type units (water)

Evaporative Coolers

In cases where it is impossible to use either an exhaust tube or a split air-conditioning unit, (normally areas with no outside access, or ceiling void) an evaporative cooler can be used to provide cool air. Evaporative coolers are very efficient and come in a variety of sizes capable of cooling small and large environments.

Exhaust tube units

With exhaust tube models both the evaporator and condenser are built into the portable unit, the unit is therefore self-contained. Whilst air-conditioning units produce cool air for the desired room it also produces hot exhaust air that needs to be removed. The hot air is removed via the exhaust tube and needs to be dispersed away from the area being cooled. The best solution is to place the exhaust tube outside a window or door, however if this is not possible the vent can be place into a ceiling void.

Split type unit

Split or PAC units have both indoor units and outdoor units connected via flexible hoses. The indoor unit produces cool air, and the outdoor unit disperses the hot air. The hoses for these split or PAC units are small, flexible and can be disconnected from the units allowing for easy installation through a small gap in either a door, window or vent.

Once you have established the type of portable air-conditioning unit for your environment you then need to calculate the amount of cooling duty you need, i.e. how many BTU or kW. The heat load for each room can vary considerably. This depends on the number of lights, the number of people, glass area facing the sun, and the presence of computers and other equipment. It is therefore essential to determine the capacity correctly.
