Portable Air Conditioners
Portable air conditioners are air conditioners that can be easily moved throughout a single building or transported from one location to another. They may also be referred to as mobile air conditioners or spot coolers. Many businesses sell and rent portable air conditioners for a variety of applications.
Air conditioner capacity is measured in tons of refrigeration, meaning the refrigeration power of a ton of ice melting over twenty four hours. One ton is equal to twelve thousand BTUs. A portable air conditioner of one ton can cool around four hundred square feet of space. Portable air conditioners are available with refrigeration of up to five tons, to cool up to two thousand square feet. Portable air conditioners are frequently used at construction sites and for military uses such as command tents, emergency cooling and telecommunications. Portable evaporative coolers are also available. Although not as powerful as portable air conditioners, they do not dehumidify the air like refrigerative air conditioners and are therefore popular for spot cooling in hot, dry environments. Their size also allows them to be used in spaces ill-suited to permanent air conditioners, such as boats, trucks and other recreational vehicles. Their maneuverability is why they are always run by electricity, from outlets or batteries.
