Air conditioning means the cooling of indoor air for thermal comfort. It refers in a broader sense; any form of cooling, heating, ventilation, or disinfection that modifies the condition of air. Any appliance, system, or machine that is designed to stabilize the air temperature and humidity within an area (used for cooling as well as heating depending on the air properties at a given time), is referred to as an air conditioner. Typically this uses a refrigeration cycle but sometimes evaporation, which is commonly for comfort cooling in buildings and motor vehicles.
