That limited scenario has changed over the last few years, as more people have become aware of portable cooling's many uses. Many buildings now require permanent or long-term spot cooling in certain areas of a facility, such as computer rooms, laboratories, assembly areas, entertainment venues, and areas that operate after hours.
In addition to permanent spot cooling, portable cooling can also be used for planned maintenance. For example, if a building owner or property management company decides to perform a major overhaul of a chiller plant, which usually requires a minimum of two to three days, portable cooling is a necessity for critical areas.
