Air conditioning (often referred to as AC, A.C., or A/C) is the process of removing heat from a confined space, thus cooling the air, and removing humidity. This process is used to achieve a more comfortable interior environments, typically for humans or animals; however, air conditioners are also used to cool rooms filled with heat-producing electronic devices, such as computer servers or power amplifiers. Air conditioners often use a fan to distribute the conditioned air to an occupied space such as a building or a car to improve thermal comfort and indoor air quality.
