What is an Air Conditioner?
All air conditioners contain refrigerators, they are devices that absorb heat from evaporating liquids and allow the remaining cool air to be released. Hot air is expelled through an intricate system of filters and cool air is delivered to the room through a complex system of condensers, fans, and coils.
Air conditioning units contain components that must remain outside and components that are securely located within a particular space. The components that remain outside funnel hot air outside. In most commercial buildings, these components are found on the roof.
