The portable air conditioner can be used in a company where computers are moved from location to location, yet are not at the main company offices. It might be out in the field, in a trailer, on a boat or in a building that does not have sufficient power to handle a central unit.
There are many senior citizen community homes and apartment buildings that cannot support central or individual ac units. These places are ideal for a portable air conditioner. The unit itself is compact enough to use in the smallest of spaces. They are powered either by batteries or with an adapter that takes no more power than a small fan. The unit is self-contained and can cool a small room enough by dropping the temperature 30 degrees in a few minutes.
Some units require that you add about 4 pounds of ice to it. It can also be used for misting, by adding water to the unit which will condition the area. The portable air conditioner can be used in small rooms containing computer servers, which happen to be away from the main company.
