A split air conditioner consists of an outdoor unit and an indoor unit. The outdoor unit is installed on or near the exterior wall of the room that you wish to cool. This unit houses the compressor, condenser coil and the expansion coil or capillary tubing. The sleek-looking indoor unit contains the cooling coil, a long blower and an air filter.
Installation of a split air conditioner is much simpler because it does not require ductwork. Rather, the indoor and outdoor units are connected with a set of electrical wires and tubing. This is good for your wallet and the environment. The ductwork required for many traditional A/C units generally increases energy expenditures, as many centralized A/C units lose a lot of energy due to heat exchange in the air duct system. Without a network of ducts, there is very little opportunity for heat or energy loss in a split air conditioner system.
This kind of air conditioner system has many advantages over traditional A/Cs. One obvious benefit is the quiet performance of a split air conditioner system. The parts of an air conditioner that make the most noise are the compressor and the fan that cools the condenser. In a split system (unlike a window unit), the compressor and fan for the condenser are located outside the room being cooled and therefore the major sources of noise are removed.
