We have looked into certain aspects of air conditioning, now it is time to look at the equipment that can be usedWhen you think of air conditioning you will probably think of fixed systems that create clean cool air in rooms, these are often a big system circulating air through grates in the walls or up through the floorThis is not the only type that is available though, Portable Air Conditioning Equipment is another type, these units vary greatly in price and power.

You could pick up one of these for as little as £299; at this price it is likely to have a power output of 3Kw and the ability to cool a room with an area of up to 250ft squared (23.2m squared)That is based on a typical ceiling height of 8ft (2.4m)Airconco is a well recognised manufacturer of these types of systemsThey offer more powerful units with outputs of 3.5Kw and 4.1Kw (3.5Kw will cool a room with an area of up to 300ft squared and the 4.1Kw unit will cool an area of up to 350ft squared)

Another manufacturer of these units are Airrex: their units are even more powerful and designed for industrial purposes; they have higher cooling outputs ranging from 17,000 btu â€" 25,000 btuThe smallest system has the ability to cool an area of up to 425ft squared and the largest is capable of cooling areas as big as 625ft squaredAnother benefit of these are the three flexible / directional cold air outlets, they are extendable and can be pointed towards any area of the room you require, should you need to isolate air to a certain place these are perfect.
