The basic choice can be made from one of the following:
- Evaporative coolers (swamp coolers)
- Portable Exhaust tube Air Conditioning
- Portable Split type Air Conditioning units (refrigerant)
- Portable Split type Air Conditioning units (water cooled)
What should I consider before choosing a portable air conditioner?
The most important factor to consider is the amount of cooling duty that is required for the area to be properly cooled. The amount of cooling duty required (measured in BTU or kW) will be impacted by several issues. i.e. size of area, number of people populating the area, numbers of items that generate heat e.g. PC, photocopiers, fax machines etc. Also the number of windows and the direction of the sun, i.e. buildings with south facing windows will require more cooling duty. Calculating the correct level of Air Conditioning duty required is important as the correct decision can save hire costs and deliver the perfect cooling solution.

For a very quick guide the following can be used:
|7,500 BTU (2.2kW)||150 square feet|
|9,000 BTU (2.6kW)||250 square feet|
|10,000 BTU (2.9kW)||300 square feet|
|12,000 BTU (3.5kW)||400 square feet|
|13,000 BTU (3.8kW)||450 square feet|
|14,000 BTU (4.1kW)||500 square feet|
Different factors can reduce the effectiveness of portable air conditioners. Here are a few solutions that might increase or decrease BTU’s if you suspect the effectiveness of your portable air conditioner is going to be altered by an outside factor:
- Reduce your required capacity by 10% if your room is heavily shaded.
- Increase your capacity by 10% if your room is very sunny.
- Add 600 BTU to your capacity for each additional person (beyond two people) that regularly occupies the same room.
- Add 4,000 BTU if the room is a hotter than normal environment i.e. similar to a kitchen.
Portable Air Conditioners
The type of Portable Air Conditioner you choose may depend greatly on where you intend to exhaust it. Exhaust tube Air Conditioners remove the heat produced by the refrigeration circuit via exhaust tubes. Ideally the exhaust tube is Directed out of an adjacent window, however in some circumstances the heat can be removed via a suitable ceiling void or into other unused space. Each model and size of Exhaust Tube Air Conditioner is capable of different performance. For example with the following models available from All Seasons Hire the exhaust tube can be extended to a maximum of 1.8 meters from the air conditioning unit:
Portable air conditioner model – CoolAir 14 = 2.5 meters
The Coolair 14 is a very popular portable Air conditioner. Small and compact, this model unit has a smart modern look and is very easy to install and use, despite its size it produces a very powerful 4.1kW (14000 BTU) of portable air-conditioning, it also has a fully automatic thermostat and comes complete with a remote control.
Portable air conditioner model – CoolAir 15 = 2.5 meters
The Coolair 15 is a very popular portable Air conditioner; it is slightly more powerful than its sister the Coolair 14 producing a credible 4.4 kW (15000BTU) of cooling. Small and compact, this model unit has a smart modern look and is very easy to install and use. It has a fully automatic thermostat and comes complete with a remote control. In more sophisticated models with high powered fans the exhaust tube can be extended longer for example.

Evaporative coolers (also called swamp, desert, or air coolers) are devices that cool air through the simple evaporation of water. They differ from refrigeration or absorption air conditioning, which use the vapor-compression or absorption refrigeration cycles. In the United States, small-scale evaporative coolers are called swamp coolers by some users due to the humid air conditions produced. The name sump cooler is also used. Air washers and wet cooling towers utilize the same principles as evaporative coolers, but are optimized for purposes other than air cooling.
Evaporative cooling is especially well suited for climates where the air is hot and humidity is low. For example, in the United States, the western/mountain states are good locations, with swamp coolers very prevalent in cities like Denver, Salt Lake City, Albuquerque, El Paso and Phoenix, where sufficient water is available.
Evaporative air conditioning is also popular and well suited to the southern (temperate) part of Australia. In dry climates, the installation and operating cost of an evaporative cooler can be much lower than refrigerate air conditioning, often by 80% or so. But evaporative cooling and vapor-compression air conditioning are sometimes used in combination to yield optimal performance. Some evaporative coolers may also serve as humidifiers in the heating season.
In moderate humidity locations there are many cost-effective uses for evaporative cooling, in addition to their widespread use in dry climates. For example, industrial plants, commercial kitchens, laundries, dry cleaners, greenhouses, spot cooling (loading docks, warehouses, factories, construction sites, athletic events, workshops, garages, and kennels) and confinement farming (poultry ranches, hog, and dairy) all often employ evaporative cooling. In highly humid climates, evaporative cooling may have little thermal comfort benefit beyond the increased ventilation and air movement it provides.
