How Does Air Conditioning Work?
How Does Air Conditioning Work?Author: Amy NuttAn air conditioner is a device which cools the indoor air by removing heat and sending it outside. The result is indoor space that has less heat making it cooler for everyone, including pets. Air conditioners can cool a room, a house, or a whole business. Air conditioners contain chemical fluid called a refrigerant which can change from a gas to a liquid and back to a gas again. A refrigerant called Freon is normally used in air conditioners. This chemical is used to transfer heat from the air inside of a home to the outside air. Air conditioners have three important parts that include a compressor, a condenser, and an evaporator. The compressor and condenser are normally located on the outside part of the air conditioner while the evaporator is located on the inside. Motorized fans help to circulate the conditioned air, while thin metal fins allow heat to disperse rapidly.
The chemical fluid comes to the compressor as a cool low-pressure gas. The compressor jams the fluid so that molecules are pressed close together which causes the temperature and energy to increase. When the fluid leaves the compressor, it is a hot high pressure gas. This gas then flows into the condenser. The gas is cooled in the condenser. When it leaves the condenser, it is much cooler and is now in form of a liquid.
The liquid goes into the evaporator.
