In the view of experts such as ASHRAE, 'air conditioning'
includes adjustment of the humidity as well as the temperature.
You'll see that most common 'air conditioners' do not meet this
standard.
An air conditioner is a device that is used to cool and dehumidify the air in a confined space, usually a room or a building. It works by drawing in warm air, removing the heat from it, and then blowing out cooler air back into the space.
