A portable air conditioner can work in all places. It can, and, usually is, placed in those areas where permanent installation of air-cooling systems is not possible. Much like a window air conditioning unit, a portable air-conditioner uses electricity to function.
Portable air conditioners are best suited for industrial places since it is possible for the unit to be rolled, carried, or otherwise transported from one location to another. This saves money because it would be a great waste trying to cool the entire warehouse. The portable air conditioner is often put to outdoor commercial use, so it has been modified to suite such conditions.
Previously all types of air conditioners ran on coolants, which is similar to the one installed on windows. Portable air conditioners use a chemical called Freon and the power is got from the ordinary 120-volt electric source. The cooling process includes the functioning of chemicals and so the air conditioner must have an outlet through a duct or window.
Portable air conditioners come in many different sizes; although the ones normally used in industrial sites are usually quite large. However, the unit is usually mounted on a base that contains wheels, rollers, or casters, thus making it easy to maneuver from one place to another.
These conditioners cool warehouses which are occupied by people in certain areas. They can be used in small offices as well has areas where temperature sensitive equipments like computers or motors are kept.
Another type of portable air conditioners has come up.Known by the rather colorful name of "swamp coolers", these units use the process of evaporation to provide cool air rather than a form of coolant. They are almost always smaller and easier to move from place to place.
They have an inbuilt reservoir from where the cooling and humidification through evaporation takes place. This compact air conditioner can be carried almost anywhere.
It can be easily taken care of by refilling the reservoir on a regular basis. Further, they are very efficient and provide rapid circulation of cool air to the smaller areas for which they are intended. They also do not require venting.
