Air conditioning (often referred to as A/C, or air con) is the process of removing heat and controlling the humidity of the air in a space. Air conditioning can be used in both domestic and commercial environments. This process is most commonly used to achieve a more comfortable interior environment, typically for humans and other animals; however, air conditioning is also used to cool and dehumidify rooms filled with heat-producing electronic devices, such as computer servers, power amplifiers, and to display and store some delicate products, such as artwork. The cooling is typically achieved through a refrigeration cycle, but sometimes a passive cooling system such as evaporation or free cooling is used. Air conditioning systems can also be made based on desiccants (chemicals that remove moisture from the air). Some AC systems reject or store heat in subterranean pipes. Air conditioners often use a fan to distribute the conditioned air to an enclosed space such as a building or a car to improve thermal comfort and indoor air quality. Electric refrigerant-based AC units range from small units that can cool a small bedroom, which can be carried by a single adult, to massive units installed on the roof of office towers that can cool an entire building. In construction, a complete system of heating, ventilation, and air conditioning is referred to as HVAC. As of 2018, 1.6 billion air conditioning units were installed, with the International Energy Agency expecting 5.6 billion units in use by 2050. Air conditioning accounts for ​1⁄5 of energy usage in buildings globally, and the expected growth of the usage of air conditioning due to climate change and technology uptake will drive significant energy demand growth. In response to, in 2018 the United Nations called for the technology to be made more sustainable to mitigate climate change. Passive cooling and passive ventilation are techniques for air-conditioning without using external power sources; they include windcatchers, evaporative cooling, selective shading, encouraging airflow, and using the heat capacity of the soil or masonry, as well as the use of better insulation to prevent heat from entering.
