An air conditioner is a device that changes the temperature of air that goes through it. Most airconditioners are for cooling air down. They work either by evaporating water inside them to make the air cool the same way that sweating cools you off, or they work by transferring heat from inside to outside by a heat pump. Some airconditioners are called reverse cycle because they can be used to heat your house too.
