Air-conditioning applications

2Air-conditioning engineers broadly divide air-conditioning applications into what they call comfort and process applications.

Comfort applications aim to provide a building indoor environment that remains relatively constant despite changes in external weather conditions or in internal heat loads.

Air conditioning makes deep plan buildings feasible, for otherwise they would have to be built narrower or with light wells so that inner spaces received sufficient outdoor air via natural ventilation. Air conditioning also allows buildings to be taller, since wind speed increases significantly with altitude making natural ventilation impractical for very tall buildings[citation needed]. Comfort applications are quite different for various building types and may be categorized as

  • Low-Rise Residential buildings, including single family houses, duplexes, and small apartment buildings
  • High-Rise Residential buildings, such as tall dormitories and apartment blocks
  • Commercial buildings, which are built for commerce, including offices, malls, shopping centers, restaurants, etc.
  • Institutional buildings, which includes government buildings, hospitals, schools, etc.
  • Industrial spaces where thermal comfort of workers is desired.
  • Sports Stadiums – recently, stadiums have been built with air conditioning, such as the University of Phoenix Stadium[11] and in Qatar for the 2022 FIFA World Cup.[12]

In addition to buildings, air conditioning can be used for many types of transportation – motor-cars, buses and other land vehicles, trains, ships, aircraft, and spacecraft.

Process applications aim to provide a suitable environment for a process being carried out, regardless of internal heat and humidity loads and external weather conditions. It is the needs of the process that determine conditions, not human preference. Process applications include these:

In both comfort and process applications, the objective may be to not only control temperature, but also humidity, air quality, and air movement from space to space.
