The name air conditioning most commonly refers to the cooling and dehumidification of indoor air for thermal relieve. In a broader sense, the term can refer to any form of cooling, heating, ventilation or disinfection that modifies the condition of air. An air conditioner (AC or A/C in North American English, aircon in British and Australian English) is an appliance, system, or mechanism designed to stabilise the air temperature and moisture within an area (used for cooling as well as heating depending on the air properties at a set time) , typically using a refrigeration cycle but sometimes using desertion, most commonly for comfort cooling in buildings and carrying vehicles.
The concept of air conditioning is known to have been applied in primordial Rome, where channel water was circulated through the walls of certain houses to cool them. Similar techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the sizzling season. Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by Willis Haviland Carrier.
