Air conditioners work in a very similar manner as refrigerators do. However, unlike a refrigerator that cools only a small insulated and contained area, an air condition cools larger open spaces such as small bed rooms, a business building or even an entire house.
Air conditioners use special chemicals that rapidly convert from gas to liquid and back again to transfer heat from inside your home or business to the outside.
Air Conditioners consist of three main parts:
- The Evaporator
- The Compressor
- The Condenser
The evaporator is located on the portion of the air conditioning unit that is inside your home or office. The evaporator consists of a serpentine tubing coil that is usually made from copper. The coil is surrounded by a aluminum fins. The evaporator takes in hot air from the outside and cools it. The fins assist in this effort as well as assist in pushing the hot air back out the evaporator. When the refrigerant enters the evaporator it is a liquid where it is evaporator into a gas. The process of evaporation needs heat to occur. Thus, during the evaporation process the heat in the liquid is transferred thereby cooling your home
The condenser is very similar in design to the evaporator but can be found on the portion of the airconditioning unit that resides outside your home or office. The condensor reverts the hot gas back to a liquid and starts the process over again
The compressor is a pump that circulates a heat transfer fluid ( or refrigerant) thru the copper coils of the evaporator and the condensor. It is located on the portion of the unit that resides outside your home or business. The compressor is the engine of the unit.
