Portable Air Conditioning

Posted on | June 28, 2014 | Comments Off

Before You Hire or Buy Portable Air Conditioning, it will help if you understand how to find the perfect match for your needs.

There are 4 principle types of Portable Air Conditioners available, each environment requiring Portable Air Conditioning is different and therefore careful consideration needs to be made prior to choosing the best Air Conditioning Solution.

The basic choice can be made from one of the following:

  1. Evaporative coolers (swamp coolers)
  2. Portable Exhaust tube Air Conditioning
  3. Portable Split type Air Conditioning units (refrigerant)
  4. Portable Split type Air Conditioning units (water cooled)

What should I consider before choosing a portable air conditioner?

The most important factor to consider 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 the correct decision can save hire costs and deliver the perfect cooling solution.

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:

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.

Evaporative coolers

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.
