Central air conditioning is commonly referred to as central air or air-con in an air conditioning system that uses ducts to distribute cooled and/or dehumidified air to more than one room, or uses pipes to distribute chilled water to heat exchangers in more than one room, and which is not plugged into a standard electrical outlet.
Central air conditioning performs like a regular air conditioner but has several added benefits:
When the air handling unit turns on, room air is drawn in from various parts of the building through return-air ducts. This air is pulled through a filter where airborne particles such as dust and lint are removed. The filtered air is routed to air supply ductwork which carries it back to rooms. Whenever the air conditioner is running, this cycle repeats continually.
As the condenser unit (with its fan and the compressor) is located outside the home, it offers a lower level of indoor noise than a free-standing air conditioning unit.
A central air conditioning system uses high velocity air forced through small ducts (also called mini-ducts) typically round, flexible hoses about 2 inches in diameter.
Using the principle of aspiration, the higher velocity air mixes more effectively with the room air, eliminating temperature discrepancies and drafts.
Another added benefit of this type of ducting is the prevention of foreign particle buildup within the ducts, due to a combination of the higher velocity air, as well as the lack of hard corners.
